Culture and International Health


            Culture is an ambiguous term. It can be, and is, operationalized differently depending on the agenda of the researcher, the topic of research, or the outcome that one is looking for. It can be observed in different levels, whether it be the culture of a country (macro), a state/territory/province (mid-range), or of a village (micro), and often times is evaluated based on the different cultural values that the researcher, knowingly or unknowingly, bring from his/her own point of view. When I say culture, I am referring to the meaning-making processes, point-of-views, and framework of a group that guides the actions and problem-solving processes of the individuals within that group (Kao et al., 2004; Swindler; 1986). Common characteristics that are threaded throughout culture are:
 1) learned from birth through the processes of language acquisition and socialization, 2) shared by all members of the same cultural group, 3) an adaptation to specific environmental and technical conditions, and therefore 4) a dynamic, ever-changing process (Kagawa-Singer 2012:357; Leininger, 1995).
                  The above characteristics illustrate the reciprocal nature of culture.  #3 in particular, “an adaptation to specific environmental and technical conditions”, brings to the forefront that culture is, in part, a result of the conditions that a community experiences as a way to not only make sense of life, but to survive.  #4 goes further to explain that culture is dynamic, not static, and will continue to change as life changes.
When I look at this definition, it makes me realize a more careful consideration of culture in developing and implementing health interventions should be a priority. It is important to ask ourselves, as researchers, not just what problem we are trying to address, but also what is creating the problem, and how culture interacts with the problem. We must take into account the size of the group we are trying to generalize about. If we are trying to create and implement a national scale intervention, we must recognize that there will be within level differences of culture that makes the applicability of that intervention vary depending on the cultural clashes within a country.  Further, recognize that culture clashes that seem to be between what we deem the “civilized” majority and the “uncivilized” minority may speak about the inequalities embedded within the social structure of that country. There are different levels of culture that need to be taken into consideration:
-Macro: national culture (values, behavior, environment)
            -Middle-Range: States/territories/Provinces
-Micro: Villages (taking into special consideration the marginalized and poorer populations that are usually silenced, and victims of social inequality)
            Without knowing who you are trying to target with your intervention, and what possible cultural differences lies between and within these different levels of organization, the effectiveness of the intervention can be entirely compromised. For example, in Dutta-Bergman’s article on the Santali (2004), trying to promote national family planning to a village whose culture revolves around large families not because they are primitive, but because the culture of their village promotes many children to bring in money and labor into their family’s income due to their marginalized status, the intervention is not going to be successful. This also points to structural violence’s role in causing harm to certain populations. Culture has become a scapegoat of failed public health interventions, but there needs to be a deeper look at how culture has arisen in populations.

Health as a human right in modern society

After the universal declaration of human rights (UDHR) in 1948, health right issues have been expanded continuously. Discussion on health as a right has reflected changes of the global society’s environment and culture. Modern society has several issues which have to be addressed in terms of health as a right. 
Rapid advances of the medical knowledge and treatment cause information inequality between doctors and patients. Though some argues that patients’ accessibility to the medical information has increased, specialization in medical treatment enables expertise to control people in the way that they want. Since patients’ health-related information is sensitive personal information as well as difficult for patients to interpret and assess themselves, collection, store, use and exchange of the information is critical issues. Medical information monopoly-related issues can be addressed as a civil right in the sense that they are related to the rights to know. Privatization of the medical treatment should also be addressed in terms of public health. Though it emphasizes high quality medical service, it generates several issues which conflict with rights to health since limited populations are capable of the access.
In addition, globalization generates transnational issues such as an increase of migration workers and refugees. Previous political efforts to ensure their right were addressed in the boundary of the nation-state, but as national boundary has been blurred, the issues such as a citizenship of the immigrants become politically sensitive and start to be considered from the universal view. In this sense, their health issues also should be approached as a human right (Toole & Waldman, 1993).
Furthermore, we should also consider laborer health. Basically, health issues of that group of people has not been broadly discussed and approached only in terms of hazard environment in the workplaces. However, as labor market becomes flexible according to the restructuring of the employment and the advent of new societal/economic system, variety of social issues has come up which promote health problems. For example, stresses from the contingent employment, layoff and employment instability cause depression, and even in extreme cases they lead serious problem such as suicide. Therefore, the labor health could be a crucial topic to be addressed in modern society.
Lastly, world’s environmental problems are also the main issues which have to be addressed from the health as a human right’s perspective since they are directly related to the health of mankind. Changes in the ecosystem including global warming increase health risk for all individuals. To ensure and realize the optimal health of the people all around the world, not only the public interventions are required such as health and medical treatment system, but also various conditions which compose of human life should be improved. Natural environment is one of the most important conditions, so it should be discussed in the boundary of health as a human right. As examined so far, societal, economic and environmental changes across the world pose several issues which can be considered in the health right perspective. Based on these general ideas, each of these issues is needed to be investigated further.

Obesity....not just for America.

Obesity is a rather large, no pun intended, problem in the United States.  When I hear the mention of obesity I immediately think of the US.  However, this is quickly becoming a problem for many other countries  across the world.  The CIA reported the top 10 countries  in the world with the highest obesity rates and five of the countries are in Oceania, four are in the Middle East and then the United States. Worldwide obesity rates have doubled since 1980.  In 2008, 35% of the adults aged 20 and over were overweight and 11% were obese. (WHO)  That was back in 2008, since then obesity rates have been rising faster and faster with each new year.  As you can see this is a problem.

The expansion in the world's waistline caught the eye of the WHO and in May of 2004 they adopted a Global Strategy on Diet, Physical Activity and Health.  "This new strategy provided recommendations for Member States, WHO, international partners, private sector, civil society and nongovernmental organizations on the promotion of healthy diets and regular physical activity for the prevention of  noncommunicable diseases. " (WHO diet).  First lady, Michelle "Guns" Obama is the creator and leader of the Let's Move program here in the US.  Her program fights to get kids moving, how to be active on a daily basis and to educate kids on eating healthy and making better choices when it comes to nutrition and health habits. (Let's Move) This effort has been wildly successful.  The efforts of the program have decreased childhood obesity by 13% in Mississippi as well as a decrease in Philadelphia, New York City and California.  (Let's Move)
The US has made it a focus to slim down our population and clean up our plates to a healthier version.  Other countries are catching on slowly. But when will this become a more urgent focus? I realize that obesity may not be a problem for all countries or has not been a problem for as long as it has been here in the US. BUT obesity is almost entirely  PREVENTABLE! There needs to be a bigger movement towards bringing global obesity rates down and then maintain those rates.  Obesity leads to a number of diseases that are once again PREVENTABLE.

Being a personal trainer for many years now, I have a passion for helping other people reach a new healthier version of themselves.  Why not a new healthier version of the overweight countries? I know that weight loss is hard work, but it can be done.  Weight loss is a joint effort and requires many resources, especially on a global scale, however the benefits of a healthy population are exponential.  With health care being such a pain these days, why not make the extra effort to work towards staying out of the hospital and doctor's office.  Healthy individuals means less money having to be pumped into poor health care infrastructures, means more people back at work and working more productively, which means a stimulus in the economy, which means a way of overcoming debt and unemployment.  


In closing, here comes the personal trainer, go out a make a healthy decision every day.  Even if it is just a small one. Every step counts and together our efforts can make the world a better place. 




Immunizing Nomadic People in Ethiopia



Due to the recent discussion about immunizations in class, I found this article from the World Health Organization very applicable. We have discussed the campaigns and case studies devoted to vaccinating children across the globe. The Expanded Programme on Immunization focuses on remote areas and populations with high mortality rates among children under 5. I recall one of the barriers to reaching herd immunity is the population of nomadic people. Since they are moving from one place to another, it becomes difficult to vaccinate their children.

Enter Ethiopia. Only 17% of its 91 million people live in urban areas. This data is evidence of the special effort needed to reach the remote populations, specifically nomadic populations in Afar. The region is also known as the Afar Depression, for its low sea-point level. The people of Afar must move around to find other sources of food and water for their livestock. Afar is also well-known for its low childhood immunization rates. DTP immunization rates for 1 year olds is far below the WHO Regional Average, at about 45% in 2010, compared with the 65% average. If DTP immunization rates are low, you can speculate that immunization rates for MMR and other diseases is also low. 

After a deadly outbreak of measles took place, officials decided to take action. The Enhanced Routine Immunization Activity previously accomplished success in immunizing nomadic families in Somali. Officials decided to replicate the same program to raise immunization rates in Afar. The program consisted of (1) partnering with local leaders, government and non-governmental organizations and international organizations like UNICEF (2) win local support (3) train health workers to administer vaccines (4) register children for immunization (5) home visits (6) coordinate adequate supplies.

The program took a total of 3 months, with immunizations traveling to the child instead of the child traveling to the immunization. Unfortunately, WHO did not provide any data or numbers showing the increased rates of immunization. Data may come at a later point in time. However, healthcare workers from the Afar health posts were interviewed and felt the campaign was an improvement from past efforts. Mobilizing local capacity was one of the most critical aspects of the campaign.

ERIA first began in Somalia. Officials believe the campaign was so successful in Somalia because of the support from community elders. Once the elder(s) in the tribe gives the approval and support for the vaccine, mothers and fathers are encouraged to vaccinate all of their children. However, it is not easy work for the healthcare workers that are delivering the immunizations. Most often, it takes hours of traveling to reach a village and there can be miles between houses. House-to-house immunization was the only way to ensure immunizations were received in this area.

It has been interesting to learn about the different methods to immunize large populations. As a public health program planner, you must take into consideration the way people live in each area. Somalia and Afar’s success may not translate to urban areas of China. National Immunization Days may not translate to areas like Afar, where families are moving from place to place. Proper planning and consideration is needed in this critical health issue.

"Be the change that you wish to see in the world."

The inspiration for this blog posting came from Dr. Einterz's lecture last night in class. "Be the change you wish to see in the world" has been dear to me since my Junior year of high school when I received a silver bracelet with this saying engraved into it. Dr. Einterz was inspirational, refreshing, and in my opinion, what we need more of in this world, especially working in the health and public health field. We have discussed many aspects of health, global health, and public health so far this semester. We have learned about approaches and interventions that have succeeded, and those that have failed. Don't get me wrong, I believe that the majority of people that invest their life into this field do so to make the world a better place, but I do believe that sometimes a very important "something" is missing. This something, is "care". In my opinion, it was totally, and completely evident that Dr. Einterz didn't feel that need to be superior, or a "know it all" when he began his work with AMPATH, but that he cared. I can understand how it would be easy to go into a country where things are falling apart before your eyes and to take control, take the lead, and do things the "Western" way, without much regard to the culture of those who you are working with. I sat amazed as he talked about the impact that AMPATH has had, as he admitted to being "ignorant and stupid", and as he referred to "we" as the partnership between IU health and those who are the head of the program in sub-Saharan Africa. His presentation got me thinking about another saying that I hold dear to my heart, "Never think that a few caring people can't change the world. For, indeed, thats all who ever have."- Margaret Mead. I believe that care is what makes AMPATH as successful as it has been, and as it will continue to be. I am thankful for those people who have the better interest of others in mind, and for those that can admit to not knowing everything and take the back seat and learn from others, even if they may not be as "educated" as we are. It really is true that we can change the world, but, it all starts with us, the individual.

Infant and Maternal Mortality Rate Industrialized Nations

The United States has a very low maternal mortality rate in comparison with the rest of the world however it has one of the highest rates when just comparing it to other industrialized countries. It is also higher than most countries for infant mortality rate. According to the central intelligence agency the United States has an infant mortality rate of 5.9 per 1,000 live births and maternal mortality rate of 21 per 100,000 births. Comparing this to countries such as japan (IMR = 2.17 per 1,000 and MMR = 5 per 100,00) or Germany ( IMR=3.48 per 1,000 and MMR 3.48 per 100,000) (1) raises the question as to why the United States’ rates are higher. As we’ve learned in class there are many factors that can contribute to death rates such as culture and traditions and these differences can also be seen in birthing practices. There has always been discussion on the best ways to give to birth whether it’s with a mid-wife, at home, water birth, c-section, or a traditional birth in a hospital, if women should get an epidural ect. There are many benefits and risks for all methods, such as laying down in a hospital allows doctors and other health professionals to clearly see the birth allowing them to identify any complications but this is also thought to be more uncomfortable for the mother and increase pain during delivery. Other methods such as using a stool or birthing ball are thought to be more comfortable and make birth easier because of the help of gravity. The mothers and babies comfort is very important but how much, if any, does one method over another increase or decrease the chances of maternal or infant death. The World Health Organization has statistics that show that c sections were used for 17.4% of all births, where .4% was thought to unnecessary c-sections. C-sections in the United States was 30.3% with 10.8% thought to be unnecessary and in Germany 27.8% of all births and 1.4% unnecessary.  One study also found that only 6% women needed a c section who received care in mid wife led centers compared to 24% (2) who gave birth in a traditional hospital. Another source also states that in Germany it is much more prevalent to use a midwife than it is in the United States and in Japan painkillers during birth are used less than in the United States.(3) There are always unpredictable issues and complications that can arise during birth that a OBGYN would be able to use their expertise, knowledge and skills to save the mother and/or baby’s life. I am not implying that one birthing method is better than another, as I mentioned before I think its most important that the mother, father and baby feel comfortable, confident and remain safe throughout the entire birthing process. Before I had a women’s health course I never would have considered using a midwife, birthing ball or anything other than the traditional method in the United States but I do find it interesting and unfortunate that the Unites States is one of the worse industrialized countries in terms of maternal and infant mortality rates, whether birthing methods contribute to that or not.

Climate Change


       
 
        Almost all of us are aware of climate change and its consequences. We also know that human activities are increasing emission of greenhouse gases and that can cause long-term climate change. In the past three decades global temperature has become warmer by 0.6°C and has caused more flooding in some parts of the world and drought in other parts. Climate change is likely to have major effect on crop, loss of biodiversity, and the supplies of freshwater, and as a result increasing number of people at risk for hunger. The impacts of climate change would be incidence of infectious disease such as cholera, malaria, meningitis and also malnutrition which is the cause of more than three million deaths each year.
        Climate change affects all around the world but more likely hits poor population in developing countries especially dry regions such as the eastern Mediterranean and North Africa.  We know that the lack of water sanitation is an environmental health issues in most African counties and that exacerbates the impacts of climate change on human health in such regions.  In 1997 heavy rain caused cholera epidemic in countries located in east Africa such as the United Republic of Tanzania, Kenya, Guinea-Bissau, Chad and Somalia. Cholera epidemic also were reported in Peru, Nicaragua and Honduras.
       While floods contaminate public water supplies with bacteria and parasites, drought increase concentration of pathogens in water supplies and causes skin infections. Drought also causes meningitis epidemic. Every five to ten years bacterial meningococcal causes meningitis epidemic in the African meningitis belt and it happens in the middle of dry season and end by start of rain season. In 1996 climate change, increased in temperature, and decreased in rain fall which influenced the spread of the meningitis in the northern Nigeria, Kenya, Uganda, Rwanda, Zambia and the United Republic of Tanzania and infected thousands of people. Severe drought also influences the incidence of plague outbreak which infects humans through the bite of rodent fleas.                                          
         The impact of climate change on human health, ecosystems, cultural, social and economic development is significant. In order to reduce the impacts of climate change there must be policies, laws and regulations, and also the government enforcement on industries to modernize their equipment in order to reduce CO2 emission level to meet with the latest standards, they should introduce a program that rewards industries who meet or bit CO2 emission at the level of standard (such as tax credit, equipment upgrade, etc.)  Public Health system should expand their efforts in more advertisement and educational programs about climate change through social media and schools. Climate change needs to be discussed more frequently and we should share our ideas and technologies globally. By appropriate interventions such as providing services for safe drinking water global health could mitigate the impact of climate change and protect public health. Climate change can be slowed down by collaboration of every individual, community, organizations and the government to make wiser decisions.

How do we guarantee the safety of public health workers abroad?

Last week, the case study in Bangladesh highlighted the training of young married women educating their peers about family planning methods.  One of my questions was how did the health workers behind the intervention ensured the security of these women and or themselves as they traveled from house-to-house in a male-dominated society, especially where the practice of purdah, or seclusion of women from public observation by wearing concealing clothing from head to toe or the use of high walls, curtains, and screens erected within the home (1) occurs.  One of the possible security measures I remember being mentioned was husbands or male relatives accompanying the female health workers to and fro.

Polio eradication has been the goal of the Global Polio Eradication Initiative, a multi-organization effort which includes the World Health Organization (WHO), Rotary International, the US Centers for Disease Control and Prevention (CDC), and the United Nations Children’s Fund (UNICEF) since 1994 (2, 5).  The polio eradication strategy includes routine immunizations, supplementary immunizations, surveillance, and targeted “mop-up” campaigns.  Today, polio is endemic in Afghanistan, Nigeria and Pakistan (2).  Every step of their strategy requires trained staff.  Earlier today, I saw a headline of a bomb attack on a Pakistani polio vaccination center, killing two health workers and one policeman (3, 4).  These attacks on international health workers have been going on for years where many believe that polio immunization is “a conspiracy by the Americans to sexually sterilise children and thereby control the population of Muslims” (5).

I tried to find more information about how this intervention was put in place, especially how foreign health workers are approaching the Pakistani, in this case.  We keep talking about voluntary participation as part of an ethical intervention, but I am curious to see what the Pakistani themselves (or any other population of interest) are saying about us and how they feel about the immunization programs for instance.  In the case of Pakistan, there seems to be an incredible level of resistance from the military and even religious leaders, so I feel as though lack of communication is to blame.  Due to all of this violence, 240,000 children missed their immunization.

Jaci previously wrote about the effect of the war in Syria where people fled their homes to save themselves from war while unsanitary conditions and water await them at refugee camps (7).  Syrians fled to stay alive, but the untold half of the story involves health workers (foreign or natives).  I have had a couple friends work for NGOs in Africa, and most recently, one of them had to be evacuated from the Central African Republic (CAR) due to a rebel coup.   All of the violence we see in the world today, especially in countries in need, prevent indigenous populations from getting help and health workers from helping, as Mercy Corps Country Director Jean-Philippe Marcoux  noted “Before the coup, the humanitarian situation in CAR was already dire. Now it’s even worse” (8).  He adds “Well, it was never really “safe” to go back in. But we knew that there were a lot of people affected and that we needed to get back respond to this emergency in whatever capacity we could.  We focused on restarting things in Bangui so we’d be operational from our country headquarters and be prepared to take advantage of even the small chances when we could get out into the field” (8).  These people are just awesome, risking their own lives to save others!







A Grain of "Golden Rice"



Genetically modified organisms (GMOs) are receiving increasing attention in the global arena.  A GMO refers to an organism that has been genetically engineered in a laboratory in order to promote, decrease or modify particular traits. Recombinant technologies may also be used to alter an organism’s DNA with genes from an unrelated species. Much of this technology has been applied to increasing crop yields and in combating micronutrient malnutrition. In 2002 Ross Welch from the USDA wrote a report in the Journal of Nutrition calling for more research in plant breeding as “doing this would dramatically contribute to improving the health, livelihood and felicity of numerous resource-poor, micronutrient-deficient people in many developing countries and would contribute greatly to sustaining national development efforts in these countries” (Welch, 2002).
An example of this type of work is the product “Golden Rice.” A rice product has been produced that is genetically engineered with plant genes so that the grains contain beta-carotene (source of vitamin A). Non-modified rice grains have the capability to produce beta-carotene, but during development, the expression of this gene is turned “off.” The addition of plant genes essentially modifies the rice to turn this gene “on.” Again, the impetus behind this crop (according to the Golden Rice Humanitarian Board which oversees the project) was conceptualized as a way to improve the nutrition of children in developing countries who suffer from deficiencies in vitamin A leading to blindness, reduced immune response, impaired hematopoesis (red blood cell production) and skeletal growth and premature death.
However, despite the fact that the technology of GMOs in general as been touted by researchers as a way to “feed the world” and as an important piece of improving global health, it faces heavy criticism in many circles. Some say efforts are not health and humanitarian focused, but profit-driven as relatively few companies and institutes control the research. In briefly researching the Golden Rice project in particular, I found a laundry list of organizations involved in funding the effort. These include the Rockefeller Institute, Gates Foundation, USAID, Philippines Dept. of Agriculture, Swiss Federal Funding, the European Commission and the Syngenta Foundation. Research has primarily taken place at the International Rice Research Institute (IRRI) in the Philippines. 
Countering this is an article from the NPR which cited the fact that the one of the individuals currently in charge of the Golden Rice project at the IRRI was also the inventor of Monsanto’s patented “round-up ready” gene we discussed in class last week. A lot of controversy surrounds Monsanto’s monopoly of the gene pool in regards to soybeans and corn and some of these voices fear a similar result as this technology becomes globalized.  Information found on the Golden Rice Humanitarian Board site does however state that free access to the technology is available to resource-poor farmers through sub-licensing and they will have ownership of their seeds (i.e. able to save seeds). Other worries include loss of biodiversity in crops, future soil infertility and dependency on a centralized food system.
These arguments don’t even begin to scratch the surface of the debate surrounding GMOs including wars over types of labeling and transparency. Could the delivery of nutritious crops in this way eventually harm developing countries if they become dependent on a particular food supply? Are the intentions of researchers on projects like Golden Rice truly humanitarian or do they become become profit-driven because of the way our regulatory/delivery system works? I didn’t even address issues of whether GMOs themselves have intrinsic adverse health effects, which is also highly controversial. I thought it was interesting that aside from the product itself, there’s a huge debate over the balance of power.

Mercury and Ruin

Mercury and Ruin
In many developing countries, a steady income is worth more than its weight in gold in providing for a family and putting food on the table. In Prestea, Ghana, however, the steady income is gold. Over 150 small gold mines can be found in the little town of ~35,000. The miners use liquid mercury to separate the gold from the other elements found in the soil in their backyards. The use of mercury is so extensive that red smog covers the town and paints the local livestock with a light-red hue. Pictures like this can be seen in the 50+ developing countries in Asia, Africa, and South America where approximately 15 million people use mercury to extract gold out of the earth. The neurological and developmental effects of mercury poisoning are concerning especially when considering the ~3 million women and children who work in environments where liquid mercury exposure is not only routine, it is part  of their livelihood. Mercury exposure in children and developing fetuses is especially concerning as it can impair neurological development resulting in losses in cognitive thinking, memory, attention, language skills, and find motor and visual special skills. Certainly not something we would want our children to be exposed to
Artisanal and small-scale gold mining (ASGM) is the largest consumer of Mercury in the world. Not surprisingly, it also is the largest contributor of mercury air and water pollution combined with only coal combustion contributing more than ASGM in air pollution. Clearly, this is an important issue that the United Nations Environment Programme is holding the Minimata Convention on Mercury from the 9th to the 11th of Oct. 2013 to address. The aim of this convention is to adopt a global policy that will protect people and the environment from harmful mercury exposures. This topic must be addressed cautiously as ASGM is a powerful way to bring wealth into an impoverished country. Gold can be sold for 70% or more of international prices making it an excellent commodity for international trade and economic growth. Already, ASGM accounts for 15% of the global gold supply and 90% of the gold mining workforce. Reducing mercury levels may be good for the environment and individual exposures to mercury, but what about the 90% of gold miners that would be out of work with no means to provide for their families? Sure they may not die from mercury poisoning, but I would bet that some of them would rather die from that than starvation.
Mercury pollution is a growing national environmental concern. ASGM, unlike industrial gold mining processes, does not typically practice sound waste management. In some cases, the waste is discharged into rivers adding to the growing concern of mercury in aquatic life. Fish species worldwide contain anywhere from 0.05 to 1.4 mg/kg with fish higher in the food chain accumulating the most mercury. This is concerning as the pervasiveness of the problem is doubly complicated as the consumption of mercury-containing fish and aquatic life is considered to cause the most harm to humans. Other forms of mercury can be inhaled as a vapor and cause effects such as tremors, kidney effects, respiratory failure, and death to name a few. The exposure method of inhalation is quite common in areas where ASGM activity is present. The processed used to extract gold with mercury involves evaporating the mercury from a mercury/gold mixture known as an amalgam. Nearly all vapors of this sort produce mercury levels that exceed the WHO limit of 1,000 ng/m3 for public exposure. These exposures could in many instances be chronic in the sense that mercury is an element and cannot be broken down except for nuclear decay.
This economic, health, and environmental issue is not one that can be easily remedied. Many do not know of mercury’s harmful effects and lack the resources or knowledge to use safer techniques. The prospect of a steady gold income is certainly a boon for the many poor who live in developing countries around the world. But at what cost to their health and the environment? How effective would a program be that empowered ASGM workers with safer, more efficient, and more productive techniques? Would it not increase the wealth of the area, encourage local doctors and nurses to stay in the area (thus curbing the brain drain), better facilitate international trade, provide money for food and clean water, provide a safer work environment, and curb mercury pollution? Perhaps we will find out after the Minimata Convention on Mercury that convenes later on this week. Let us hope this works. I really like my sushi.

Why One-Child Policy in China works?


The case study about Bangladesh’s family planning program reminded me of a similar program in China. I was impressed by the different outcomes between the family planning program of Pakistani government in the early 1960s and China’s One-Child Policy. Both of them used coercive method to ensure the execution (Levine, 2007; Wang, 2011). As a result, however, Pakistani government collapsed since the program conflicted with the local needs, while tight One-Child Policy has been sustained for about thirty years since 1979 (Levine, 2007; Coale, 2011). One issue that attracts my attention is that why such a policy, which contributes to many negative consequences, has retained for a long period in China. There are global efforts in birth control since high fertility could increase obstetric risk and the number of maternal deaths (Ronsmans, & Graham, 2006). Thus, I think looking at the role of politics and other values in China’s birth control program can offer some lessons in global health intervention in family planning.

The “One-Child” policy restricts urban couples can only have one child, unless one of the couples is ethnic minority or couples are both only children themselves (Li, 1998). The Chinese government proposed this policy to relieve the pressure of social, economic, and environmental problems (Rocha da Silva, 2006). From early 1980s to 2011, as authorities claimed, the policy had prevented 400 million births in China (Han, 2011). How credible is it? I think it appears an over-generous assumption that magnifies the benefit of birth control program. Although some independent scholars dispute the measure, it is undeniable that the policy reshapes millions of lives (Alcorn, 2013). Nevertheless, undesired consequences also occur as the policy is being conducted, such as violent abuses, forced abortion, and sex-selective abortion (Wang, 2011). The policy is challenged for violating a human right of individuals’ reproductive freedom (Wang, 2012). However, the reality is that One-Child Policy has been retained for so long. Why the heavy-handed policy can be endured by one billion of Chinese population? Except for the tough approach which formulates that breaching the role carries a heavy financial penalty (Wang, 2012), I think there are several key elements for Chinese family planning policy.

First of all, the value system of the nation on the basis of Confucian emphasizes that people should put the prosperity of the country beyond individuals interests (Li, 1998). People are taught to take their social responsibility. I recall one slogan that is prevalently used in mass media to encourage people adhere to the policy: "For a prosperous, powerful nation and a happy family, please practice family planning." It has been a consensus, since reform of new China, that families and individuals would not live a happy life without the country’s prosperity (Alcorn, 2013). This ideology of dominant Party of China was deeply embedded in people’s mind (Wang, 2012).

Furthermore, an important contributor to the policy is that the support for safe, efficient, and free or low cost contraception is available at different level in national network (Li, 1998). More than 98% of contraceptive devices and medicine are provided broadly without charge. In addition, regular health service for couples receives increasing attention, and education programs are offered as well. Enlightened by our discussion in the class, I was thinking what role the cultural beliefs about “big family” play in the family planning program? Similar with many other counties, the Chinese believe more children bring happiness to the family. To deal with this traditional norm, the education programs claim that through birth control the family expends fewer time and money on children, and thus people have more money to invest and give the child a better future (Han, 2011). After criticism and slight loose in the recent years, it is claimed that the government will have a relax enforcement of the policy as the leadership has been shifted to new leaders since 2012 (Alcorn, 2013). I think it may be a hint which indicates the strong relationship between politics and birth control program. The government now looks at the benefits of population growth that may promote economic growth.

Environmental Inequity


As we discussed water sanitation and hygiene in class this week, it was significant to know that 2.5 billion people still don’t have access to safe water, every day around 2000 children under age 5 die globally and almost 1800 of the deaths are related to water sanitation and hygiene. Even though, unsafe water, hygiene, and excreta disposal are three environmental challenges of Global Health in developing countries but Public Health systems also in developed countries face such challenges as well and most of the times they fail to improve the health of low social groups. There are many factors beyond the control of Public Health systems such as policies, laws, “inequities in regulatory enforcement,” (Frumkin) disparity in socioeconomic status, funds, and the most important one in my view is people in the communities.  When we talked about water scarcity and sanitation, the comments were made in class about people fight over water because of water scarcity or water sanitation, made me think that if people knew their rights of having sanitary water they wouldn’t fight over it among themselves. Most of the time environmental health problems persist and remain unresolved despite all the efforts that the Health organizations have made; one reason is because people may not know it is their rights to have healthy environment. The other reason is that the government and public may not be informed clearly about existence of issues associated with environmental health problems, so the role of Public Health in this situation is to inform both public and the government about those issues and delineate the ways that they can overcome the problems. If health issues are identified by public then they get motivated to collaborate with public health officials to help resolve those problems. The goal of public collaboration is to engage people in a dialog regarding the current surrounding issues and help them to provide strategic plans that they know work the best for them and their culture. The result of such collaboration is associated with achievement in environmental equity and healthy environment in shorter time. The next step is addressing the environmental health issues to the government and those who provide funds to support such programs by demonstrating the collected data and evidence, and also encourage people to participate in order to have their voices heard. Public health organizations also should address “economic and social factors such as housing, transportation, job creation, green space, and recreation-factors,” (Frumkin) which contribute to health and well-being. In addition, the cost effectiveness of such programs seem superior to other interventions of public health programs in this matter. Last but not least all of these efforts are impossible without having motivated leadership, people commitment to change, and well establish strategic plans.

Cilantro for Safer Water?



As we have been discussing the importance of safe drinking water in class this week, I stumbled across an article in the Journal and Courier that addresses this issue and a potential solution (for some drinking water problems) that is coming right from our community. There is currently ongoing research at Ivy Tech (here in Lafayette, IN) that is examining the ability of cilantro to purify drinking water. According to the research cilantro is a “biosorbent’ substance that can absorb lead and other toxic heavy metals from water. The research team went to Mexico and experimented with various local plants and flowers to see if any had purifying effects and cilantro did! Other plants related to cilantro, such as parsley and cilantro, also seem to have some purifying capabilities.
Usually the only ways to remove these potentially harmful metals from the water is through extensive and expensive filtration systems, such as activated carbon filters, cation exchange softeners, distillers, and reverse osmosis ranging anywhere is price from about $40-$1200. These are often not an option for those communities who struggle with poor drinking water due to heavy metals. However, if cilantro (which is quite abundant in areas such as Latin America, the Mediterranean, the Middle East and Asia where people struggle with heavy metals in their water) could be used to purify water by simply placing cilantro into tea bags or reusable water filters that would be a much simpler and more feasible solution for many people than an expensive water filtration system. Another benefit is that cilantro is a renewable, fairly inexpensive resource that people could grow in their own backyard or even inside their households.
If the research truly proves that cilantro can effectively and safely remove heavy metals to a level where they are no longer toxic to humans, just imagine the health implications this could have for many people worldwide. For example, if the amount of lead and arsenic found in some drinking water could be lowered; fewer people would suffer from the life-long disabling effects of these metals.
I definitely believe that research, such as this project, are critical to solving some of the world’s health issues. This research team went to where the problem existed and searched for affordable, simple solutions within that area. It just so happens that what they found in Mexico can also be applied elsewhere in the world. One downfall, however, is that cilantro only treats heavy metals in the water. This solution does not address other causes of contamination, such as bacteria, viruses and parasites, which are major sources of disease and illness around the world. However, perhaps a combination of solutions such as cilantro treatment, cloth filtering and boiling of water could resolve many of these health issues. Although these solutions seem simple, and they are compared to some other solutions, they would still require a good amount of education and resources to get people to understand and be able to effectively use some of these methods.
