Which of the following study was conducted to determine that community health education contributes to reduced risk of cardiovascular disease?
The Stanford-Three-Community Study - To determine whether community health education can reduce the risk of cardiovascular disease, a field experiment was undeaken in 1972 in three nohern California towns with populations varying between 12,000 and 15,000. In two of these towns intensive mass education campaigns were conducted against cardiovascular risk factors over a period of 2 years. The third community served as a control. People from each community were interviewed and examined before the campaign began and one and two years afterwards to assess knowledge and behaviour related to cardiovascular diseases (e.g., diet and smoking) and also to measure physiological indicators of risk (e.g., blood pressure, serum cholesterol,, relative weight). In the control community, the risk of cardiovascular disease increased over the two years, but in the intervention communities there was a substantial and sustained decrease in risk. The net difference in estimated total risk between control and intervention samples was 23-28 percent. Ref- Park&;s textbook of preventive and social medicine 24th edition.
