It defines community diagnosis as a quantitative and qualitative description of citizen health and influencing factors, including perceptions. The general framework involves 7 steps: 1) defining the community; 2) gathering health information; 3) measuring health conditions; 4) planning/organizing services; 5) integrating with the health system; 6) intersectoral coordination; and 7) community involvement. The goal is to estimate problem magnitude, analyze trends, and stimulate action to improve community health.
