Epidemiologic data analysis forms the backbone of evidence-based community health practice in Kenya. Understanding how to identify and interpret data from various epidemiological research designs enables health professionals to develop targeted interventions for disease prevention and control. This chapter equips community health practitioners with the skills to discern appropriate study designs and apply analytical results effectively across diverse health conditions prevalent in Kenyan communities. The focus on infectious diseases, non-communicable diseases, environmental exposures, nutritional disorders, and mental health aligns with Kenya’s public health priorities.
Epidemiological research study designs provide structured methods to investigate the distribution and determinants of health-related states or events in populations. Correctly identifying the design used is essential for interpreting findings accurately and applying them to policy or practice. In Kenya’s community health context, study designs must be selected considering resource constraints, disease burden, and population characteristics.

It explored different study designs including experimental, observational, analytical, and descriptive types, explaining their usefulness in public health investigations. The application of analytical study designs was examined in the context of epidemiology research guidelines, emphasizing their role in establishing causal relationships. Observational study designs were also discussed, illustrating how they contribute to monitoring and understanding disease distribution. The chapter covered the identification of samples and methods for collecting exposure status and health outcomes to ensure accurate data analysis. It further addressed the determination of disease causes and their effects on human populations, considering infectious diseases, non-communicable diseases, environmental and occupational diseases, nutritional and metabolic disorders, as well as mental health disorders. Overall, the content provided a comprehensive framework for interpreting epidemiologic data to inform community health interventions.
