What I learned from International Health

At the beginning of the semester, I knew hardly anything about global/international health.  I still think this is much to be learned, but taking International Health and World Food Problems has helped a lot.  I believe the class as a whole agrees that positive deviance is very important.  At least it appeared that way from the last class.  I personally think globalization was one of the most important concepts we talked about.  Globalization needs to be understood or at least thought about.  It has always been around, but we do not think about it.  Globalization has led to many changes around the world both good and bad.  Even if it involves the same people or object, it can have different effects.  Look at what we learned about women and globalization.  It is starting to become more acceptable for women to seek out paid work.  I do not know where this started, but the United States has obviously been supportive of paid women’s work.  The glass ceiling aside, women are allowed to work in developed countries.  Having more women in the work force has uncovered problems that we were not aware of before.  The stress of having to work a paid job, raise a family, and do all other day-to-day tasks is daunting.  Women are strong enough to handle, but societal norms are not making it easy on them.  Finding good childcare and financing it are extremely difficult for many.  Hopefully, we will come up with better solutions in future years.  We have are all capable of being this solution.  I talked about globalization because I found it to be so important.  There were other concepts we learned about that are also significant.  Wherever I end up career wise, I believe I can use the concepts taught from these courses to improve how I address the issues I face. 

Reflection

       As the semester is coming to an end, I reflect on what I have learned in all of my classes and how they all relate to one another. While they all had their specific focus areas, one thing that stuck out to me is the depth that public health interventions must entail in order to be successful. No public health issue can be moved in a positive direction by using a narrow approach. Individual, interpersonal, structural, physiological, and societal factors all have their own impact on one's health. Also noted, that as much as public health professionals believe that an intervention they have created will be successful, they cannot initiate it without proper funding and resources, which is a big obstacle in this field. In addition, policy changes are most often out of our control and policy can be very beneficial or detrimental to a targeted health behavior. Specifically, in regards to global health, I have learned that there is a lot to be done around the world. There are so many alarming health disparities that I was not completely aware of prior to this class. Like all interventions, we must understand what our target population wants and needs what they will respond to. Also, we must make changes that will make it able for these communities to sustain better health once the intervention is over. We cannot put a quick, simple fix on a long, complex problem. While there are many obstacles and challenges in public health, and while some tasks may seem way too out of reach to tackle, we can all make a difference if we put our mind, time, and effort into it. I believe public health is a very rewarding field, and the impacts we have the ability to make on people's lives is worth all of the hard work we will put in as public health professionals.

Preventing Prevention: What's stopping us from using contraceptives?

Contraception is a public health issue with worldwide prevalence, complicated by difficulties with access, proper use, stigma, cost, and more.  Unfortunately, many misconceptions exist that limit use of birth control, whether through public policy or individual choice.  Public policy that restricts birth control access is very difficult to fight, being that it is grounded in social norms and cultural beliefs of the majority or of the governing party.  For example, I have been researching women’s health care access in Italy, where emergency contraception is still prescription-only; this barrier is even more problematic when you consider the time-sensitive nature of emergency contraception.   One study found that some Italian doctors will refuse to write prescriptions because they misunderstand the medical mechanism, considering it to be like an abortion rather than a true prevention of fertilization; this forces women to try clinic after clinic until they can finally get a script for what should be an easily accessed method of pregnancy prevention (Bo, Casagranda, Charrier, & Michela Gianino, 2012).

In addition to public policy challenges, personally- or societally-held misconceptions can limit birth control use in practice, even if it is not limited by policy.  A recent article from Science Daily (“Fear of gaining weight may influence contraception choices,” n.d.) discussed the very real fear that many women have of gaining weight due to oral contraceptives, and how this deters them from using this method.  The study they referred to (Bhuva, Kraschnewski, Lehman, & Chuang, 2016) found that women who were overweight or obese were more likely to use either highly effective forms of birth control (IUD or implant), or minimally effective forms (condom, withdrawal) to none at all, but had lower rates of pill use.  Pill usage has been linked in the public discourse to weight gain, but literature review has shown no true correlation (Gallo, Lopez, Grimes, Schulz, & Helmerhorst, 2006).  I have many friends who have stopped or never started oral contraceptives because a fear of weight gain, but in reality any initial weight gain is usually due to a shift in water weight and normalizes after a few cycles of the pill.  The fact that this study showed that overweight or obese women tended to avoid the pill is concerning, because some of them ended up using less effective to no method of contraception.  Just last week I was reading about factors that influence pregnancy outcome: pregnancy intention leads to better outcomes for mother and baby, but more than half of all pregnancies in the U.S. are unintended (Frayne et al., 2016).  This means we must fight any and all misconceptions about birth control that are preventing women from using it, in addition to access and policy barriers, here and throughout the world.  Proper education about contraception, free of misconception, myth, or stigma, is vital.

Social Media & Health Promotion

Social Media & Health Promotion

In an age of globalization and the rapid growth of technology, developing countries are increasing their use of social media and have gained access to technologies including cell phones and internet. As a result, many health interventions have utilized social media as a communication tool in order to change health behaviors due to its ability to increase information access as well the ability for such programs to be customizable to a population (Levac & O’Sullivan, 2016).

However, as a relatively new medium, I have questioned the unintended consequences of such an outlet on a variety of factors. For instance, what impact does this have on social skills and potential it has on limiting physical activity among a given population. Also, with the reliance of such interventions on the internet and technologies, are they effective and reliable in global health initiatives? How may we as health professionals experience the benefit of social media as an effective tool and at the same time, have little negative impacts on the population we are targeting. Also, researchers such as Levac and Sullivan (2016) question the long-term effectiveness of such strategies as the nature of technologies is one that is in constant change and fluctuation. Social media sites also are sensitive to the nature of information and the ability for unreliable information to be published and referred to in at-risk communities. This lack of control increased the need to educate the public on ways to effectively utilize such social media tools for it to be effective.

As I read this article, I was interested in your thoughts as public health professionals from various fields and how you think social media may or may not have unintended consequences in utilizing it as a strategy in global health initiatives? Should we continue to use this as a reliable communication tool?

'Tis the Season for Test Anxiety

            As we are heading into finals, my personal thoughts are constantly being about final projects, exams, and presentations.  I do not know about you all, but even though we are in graduate school, I experience peak anxiety during this time.  While for some classes we might not have written final exams, we continue to have finals that determine large parts of our overall grades.  Test anxiety is a curious thing.  Why do some people feel it so harshly while others are hardly affected?  What is the science behind this?  Test anxiety is correlated negatively with academic examination performance (Aysan et al., 2001).  Salehi and Marefat categorized anxiety as trait and state anxiety.  Trait anxiety is a tendency towards anxiety on a relatively stable scale.  This type anxiety is basically a personality trait.  These are people that tend to also have some level of anxiety.  State anxiety is situation-based anxiety.  State anxiety is also considered part of trait anxiety, but will arise during situations that cause individuals stress.  The researchers have found that test taking while experiencing a language barrier is even worse (2014).  Aysan et al. discussed different methods for dealing with test anxiety.  Their sample population was Turkish MA postgraduate students.  They recommended practicing yoga and meditation to deal with everyday anxiety.  The researchers’ main focus was to look into performing pranayama or a type of Hindu yoga.  Pranayama is regulation of breathing that has been shown to control and reduce anxiety during test taking (2001).  I chose this topic to write about not to get everyone down with thoughts of finals, but to give at least an understanding of test anxiety.  Hopefully, this blog makes you realize that everyone has the potential for test anxiety.  Good luck on all of your finals whether they are exams, presentations, projects, etc.  You can do it!

Public Health as Global Health

Education informs the public about health and unhealthy behavior choices and it is up to the public to decide whether they are going to change their behavior based upon evidence.  One would think that when someone is informed of negative health effects and the benefits of pursuing one course of action over the other that they would always make the correct choice but that is not how we operate as human.  Also, we do not always have the tools necessary to make the correct decision.  Also even with the correct tools we may not have the means or mode to make those corrective changes.  It takes more than just education, even regulation is not a cure all because some of the same problems that I just spoke of will still exist.  When we look at the cause of death and disease that are plaguing the population we would be incline to say that people choose their own health, but I beg the differ.

The top three cause of death are smoking, poor diet and physical inactivity followed by alcohol consumption.  Behind each of these cause of death is an underlying problem that we may be able to see or fix with changes in health behavior.  Some of the causes of why people drinks, smoke, overeat, etc., are systematic and physiological. Without looking at the root of these issues can we treat the problem or are we only putting on a band aid?  I would say in order for people to change their behavior and move towards better health we must look at the underlying causes and address those as well. People living in food deserts and in poverty are not overweight because they may just love to eat, but because they are not eating the appropriate things or because their body has stored fat due to many days of lack of food. When these people do eat they are not thinking about nutrition, but survival.  The idea of survival overrides the knowledge of health. Also what we eat does make a difference.

In today’s society we are encourage to eat better, eat healthier, however the foods that are affordable are not healthier food.  Organic food, cost about twice that of regular food.  Buying junk food could cost a dollar, whereas fruit and vegetables could range from $1/lb to $4/lb according to the season. So yes, education does work, but survival is necessary.  With education should also come measures to reduce consumer cost at the grocery stores! Many of the fruit and vegetables when not bought would be thrown away, but this does not make national new nor does it come into account when making statements regarding the health of a nation.  There are many factors that go into why people are unhealthy, and some of those are income inequality, access and means.

In conclusion, No, I do not believe that people choose their own health.  Many factors go into this equation along with what is in the environment, additives in the food etc.

Global Effects of the Tobacco Industry

As I was driving home one evening, I noticed a construction worker carrying one of my favorite things: coffee; and, one of my least favorite things: a cigarette.  I have always been curious about the global numbers of smoking and the effect of the tobacco industry in developing countries, so I decided to do a little more research for my blog post this week.

            In a study by Jha & Peto (2014), researchers look to an interesting ratio to measure the success of tobacco control.  In developed worlds (USA, Europe, etc.) among men and women 45-64 years old, there are about as many current smokers as there are former smokers.  In contrast, in developing countries, among in this same age category, there are much fewer former smokers than current smokers.  This shows that while smoking in the developed worlds has plateaued or even decreased, it has increased in developing worlds (Table 1).

            Why the decrease in developed countries and not developing countries?  Some point fingers at the effects of advertising – according to WHO (2013), one third of cigarette use that starts in youths occurs as a result of tobacco promotion and advertisement.  Attracting new users is the main reason tobacco companies spend tens of billions of dollars on advertising, promotion, and sponsorship (WHO, 2013).  The effects of advertisement bans are especially visible in Australia, where already existing bans have been strengthened by the introduction of “plain packaging” in 2011 (Jha & Peto, 2014).  Out of curiosity, I investigated these effects a little further and found Figure 1 on the Australian Government’s website (2016).

Others may point a finger at tobacco pricing – doubling the price of cigarettes in developed countries and tripling the price in developing countries has the potential to reduce smoking worldwide by a third.  In the US and UK, cigarette consumption has taken nearly 30 years to reduce by half.  In contrast, with the use of large tax increases, France and South Africa reduced tobacco consumption by half in just 15 years (Jha & Peto, 2014).

 How do we reduce tobacco use while respecting the rights of a TNC?  What are some unforeseen consequences of some of these interventions (ban on advertisement, increased taxation, etc.)?  What other global effects do you see?  Think about positive deviance that we learned about this past week, what are the areas with low numbers doing right?

Pediatric Dental Caries and Food Insecurity

Dental caries is a major public health problem. It is considered to be the most prevalent chronic disease worldwide. Pediatric dental caries not only causes pain and eating difficulties, it also affects speech, esthetics, sleep, growth pattern, social communications, self-esteem, academic performance, and quality of life.  In some conditions, untreated oral infections maybe so severe to the extent of causing systemic manifestations and consequently threatening children lives.

Low socio-economic status (SES) has been identified as a strong determinant of dental caries among children. As low SES is strongly linked to food insecurity, it is worthy to ask whether food insecurity can be a potential risk factor for this global threat.

Families that suffer from the food insecurity tend to prioritize quantity rather than quality in making their food-purchasing decisions. For example, they may go for sugar sweetened beverages that are less expensive and more accessible, however, in the same time, has a damaging effect on their children teeth.  Food insecure households may also live in food desserts which limit their food choices to processed food and snakes especially in the era of globalization where transnational corporations (TNCs) find such places as easy markets for a guaranteed high profit. Such types of food subject children to highly refined carbohydrates which are strong predictors of dental caries. Additionally, children living in food insecure houses, especially in the developing world, may take the responsibility of managing their food resources and options. In most cases, such management usually take the form of increasing the frequency of small non-healthy snakes that increase the periods of exposing their teeth to cariogenic food resulting in ideal conditions for oral bacteria to produce cariogenic acids that further potentiate caries risk.

Nowadays, most interventions tackling the global threat of dental caries focus mainly on preventive oral health behaviors such as teeth brushing, flossing, fluoride application, dental sealants, …etc. Although, such issues are extremely important, they can be potentiated by taking into consideration the social determinants of the threat and by addressing food insecurity especially within vulnerable populations who struggle under harsh structural and financial conditions.
