How are Non-Infectious Diseases Studied in Epidemiology?
Epidemiologists use various methods to study non-infectious diseases:
1. Descriptive Studies: These studies describe the distribution of diseases in populations according to age, gender, ethnicity, and geographical location. 2. Analytical Studies: These include cohort studies, case-control studies, and cross-sectional studies to identify and quantify risk factors. 3. Experimental Studies: Randomized controlled trials (RCTs) are used to test the effectiveness of interventions aimed at preventing or treating NCDs.
