• Case control study: compare exposure pattern, odds ratio
• Types of cohort studies:
  • Non-concurrent (retrospective)
  • Prospective (future-oriented, start now and move forward)
• Cross-sectional study: prevalence assessed at a single point in time

Topic 3: Health Indicators

• Best indicator for community health status: Infant Mortality Rate (IMR)
• Colombo Plan: providing cobalt therapy units for health sector
• Potential Years of Life Lost (PYLL): due to premature death, used in DALYs calculation
