8 weeks complete, 7.5 to go. This semester is focused on grasping a basic knowledge of the underlying sciences of public health. I'm not as much of a science person, so it's been a little 'over the top' for me. However, science and professors are great at proving things, including why their classes are relevant. And I agree with the importance of finding solid evidence before making a real recommendation to real people about their health.
Let's start with epidemiology, which is essentially a structured way to identify determinants or risk factors of health and disease. Realization #1: To "study" something here doesn't mean to look at it for awhile until it's temporarily memorized or generally understood. It means to conduct an actual study, with money, that includes analyses, methods and results with hopes of finding an association between an exposure and an outcome. I'm learning all about exactly how an investigator does these, even though I'm not sure I will ever do one myself (doubtful by the end of class!). I AM learning how to critique and interpret them, though, in order to make generalizable statements through program or policy. Aha.
Next, and very much related, is biostatistics (I feel like I'm writing a paper, this is horrible). Biostaticians do all of the analyses on population data that epidemiologists collect. I'm back to calculating p-values, 95% confidence intervals, and chi-square tests with fancy computer programs to compare risk proportions in multiple groups, just so I can talk the language of the study people.
On a totally different spectrum, health policy and management: how the health care system is and isn't flawed. Mostly IS. The overall feel I get in this class is that hospitals, health care, doctors, long-term care, prescription drugs, mental health, and everything else is in big trouble in this country and there's nothing that's going to fix it. Unless I do something about it. Great! I'm already trying to help the poor prevent diseases, and now I need to fix their treatments when they get sick? I mean, 3 hours on a Tuesday night, who would enjoy this class? God bless good doctors and nurses out there! I'm glad I know a few that can give a realistic balance:)
A little more up my alley is environmental heath, sadly and probably my first and last such class here. While I can tell you about greenhouse gases, toxicants, landfill management, biological vectors, and 'nucular' power, I am also disturbingly aware of the hazards of such things and feel I may have been poisoned with lead as a young child (not intentionally, mom and dad!). jk...mostly...
Newly added to my agenda (as of yesterday) is an international health writing course. This one looks like it's going to be really fun and useful. I'll get to refine my writing skills specifically by focusing on concise language (like all you need to know in 250 words or less!), learn how to solidly interpret evidence-based public health studies, and dive in detail into two HIV studies from Tanzania and Uganda. Keep your eyes out for a much more concise Finals Report in December, after I have taken this class!!
Finally, my favorite (and my concentration, so this is a good thing) is studying public health from the perspective of the social and behavioral sciences. We study (in the normal sense) a lot of theories and models on human behavior from tons of social disciplines, and then learn how they are all flawed even though they are widely accepted (do I sense a theme here?). Well that's the general consensus. Most theories (including modern economics) explain that people always behave in a rational manner and in their own best interest when they have the information they need to do so. If this were the case though, then more people, if not all, would choose not to smoke or eat fatty foods or do drugs, for example, since everyone knows these things are bad for us. Clearly, there are other environmental factors at play, which are rarely considered in public health interventions. In fact, you and I both behave in a predictably irrational manner almost all of the time. In a sense, I am learning how to 'influence' people's behaviors toward certain health goals (this works in other areas of life!) by finding out what's important to them. I also get candy and prizes regularly in this class and get to watch movie clips:)
Ok I'm done and thinking maybe I should forget the real homework tonight - I feel ready to graduate! Thanks for your listening ear (eye?). Feel free to offer your muses and offenses and what-nots! I'd be happy to share more (if that's possible)! Don't forget to vote!!
