Ultimately, the paper will be on the effect of enhanced physical activity or change in diet on the risk of developing X chronic disease . chronic diseases : 1) coronary artery disease , 2) stroke , 3) hypertension , 4) dyslipidemia ), ) diabetes (type ), 6) obesity, 7) osteoporosis , or 8) Cancers. You’ve already decided on an area You will need about 11 references . You’ve already done one. 1. Definitions (possibly several references). You don’t need a formatted AB for this. What you need is an overarching body’s (e.g., American Heart Association, Centers for Disease Control) statement with agreed upon definitions for what you are reporting. For instance, you need a definition for hypertension, and any other associated terms if that is your area. 2. Magnitude of the problem (several probably ). You don’t need a formatted AB for this, either. However, again you need references that spell out the size of the populations affected and costs of the disease you are reporting on. Include data on prevalence, incidence, economic cost to the US/world directly and indirectly , etc. 3. You will need a formatted AB (as per the Early AB) for these: A. Meta- Analysis (1 ref) Shows that the research in this area is reliable and consistent B. X-sectional study (1): Good for prevalence and showing correlation with comparison of PA non-PA or good vs. poor diet on outcome . C. (Retrospective) case-control (1): Good for prevalence differences ultimately developing odds ratios (OR) D. (Prospective) cohort (2): Good for incidence differences and developing relative risk (RR) E. RCTs (2 refs; experiments that manipulate a variable): Good for causation and showing differences between those who are involved in the factor (e.g., good diet ) and those who are not. This is good for helping to describe mechanism (biological plausibility). Animal studies are allowed here. F. Negative study (1): Sometimes data/research refutes positions. A good researcher acknowledges and reports this. You will earn points to the extent you cover all the above adequately. Remember to be brief and to the point, i.e., concise. A good job done here will help you write a decent paper.
