HLTH 101 Fall, 2011 TOPIC 3. CAUSES OF CHANGES IN HUMAN HEALTH STATUS In the previous topic, we established that health status among human populations can change over time, thus establishing the first of our “first principles” of health research and practice. What about our second “first principle”? Can we determine the causes of these changes? In this topic, we will survey what are believed to be the main contributors to these changes in human health status over time. Note that I’ve used the term “contributor” instead of the term “cause”. Think about this for a while and see if you can figure out why I chose to use this term. As we work through these contributors, keep in mind that we are, without necessarily realizing it, developing the concept of “determinants of health”. In the next topic, we’ll see that population health researchers often organize their understanding of changes in health around a list of a half-dozen or so determinants of health (sometimes also called the “broad” determinants of health). Personally, I don’t like the term “determinants” and would prefer to use the word “contributor”. However, determinants is the accepted word and so we’ll use it in this course. Finally, keep in mind the third “first principle” of health research and practice: that we can knowledge of the causes of changes in health to improve health status, if not of individuals, then of populations. As we work through this lecture, think about how we could use our newfound knowledge to improve human health. RECOMMENDED READINGS: i. Armelagos, et al. (see previous topic) ii. Omran, et al. (see previous topic) LECTURE NOTES: Recall 1 st principle # 2: WE CAN LEARN THE CAUSES OF CHANGES IN HEALTH over the past 150 y, there have been greatly reduced infectious disease rates in developed countries why? at least 4 possible reasons: 1. socioeconomic development

HLTH 101 Fall, 2011 beginning in the late 1700, but accelerating during the 1800's, there was increased social activism leading to improved working conditions, better labour laws, more universal education, etc. these changes lead to a reduction in some aspects of socioeconomic inequality, and we know that such inequality affects health status even today, the gains made during the last two decades in reducing mortality due to heart disease is only now filtering down to the lowest social classes problem: how does socioeconomic status (SES) affect health? perhaps through increased nutrition and creation of public health
