Ten-year evaluation of hypertension, overweight, cholesterol, and smoking control: the CHAD program in Jerusalem. Community Syndrome of Hypertension, Atherosclerosis and Diabetes.


Control of hypertension, overweight, hypercholesterolemia, and smoking is a major objective of the CHAD program, a multifactorial cardiovascular risk factor program built into a family practice, which has operated in a neighborhood of western Jerusalem since 1971. By 1975-1976, there was a significantly larger decrease in risk factors in this population than in a neighboring population receiving ordinary medical care. Follow-up based on clinical records of a cohort of 441 people exposed to the program until 1981 revealed that the mean blood pressures decreased and the prevalence of hypertension continued to decrease between 1976 and 1981, from 12.5 to 9.1%. Prevalence of cigarette smoking among people ages 30 years or more also decreased in this period, mainly due to a decrease in heavy smoking, at a time when national surveys provided no evidence of a smoking decrease in this age group. Effects on overweight and cholesterol were not demonstrated during this period. This 10-year evaluation demonstrates the effects of intervention by primary care practitioners in the framework of a community-oriented program.
