Epidemiology Research Assignment: Public Health Analysis

This epidemiology research assignment addresses several key concepts in public health. The assignment begins by calculating prevalence and distinguishing between point and period prevalence using a case study of congestive heart failure. It then explores incidence rates and compares them across different regions, analyzing statements about the number of cases and risk factors. The assignment continues by calculating cumulative incidence in an army base scenario, considering personnel turnover. Further, it delves into person-time incidence rates and analyzes HIV/AIDS prevalence in different population groups, including comparisons of crude and age-specific prevalence, and discusses the appropriateness of comparing crude prevalence between groups. The assignment concludes with an analysis of study designs, identifying them in given scenarios and explaining the key features that support those choices, including an experimental design focused on coronary artery disease and a quasi-experimental design investigating meat consumption and colon cancer. Finally, it analyzes a research abstract, identifying the research questions, exposure, outcome, and study design related to gait speed and mortality in older adults.
