Family (parental) history and prevalence of hypertension. Results of a nationwide screening program.

In a nationwide screening program, blood pressure measurements, family (parental) histories of hypertension, and self-evaluations of weight class were obtained for more than a half million people. Positive family history was associated with hypertension prevalence double that found in persons with negative history and was independent of weight. When overweight was also present, however, hypertension prevalence was three to four times as high. Hypertension was more likely to have been previously diagnosed in screenees if family history was positive. However, such screenees did not have a higher proportion receiving effective treatment than those with negative family history. When an index case of hypertension is found, other family members should be examined. For persons with positive family history, nutritional-hygienic recommendations to avoid overweight may be important in reducing the risk of becoming hypertensive.

Weight and blood pressure. Findings in hypertension screening of 1 million Americans.

In the nationwide Community Hypertension Evaluation Clinic screening of more than 1 million people, the group classifying itself as overweight had prevalence rates of hypertension 50% to 300% higher than other screenees. Frequency of hypertension in overweight persons aged 20 to 39 years was double that of normal weight and triple that of underweight persons. Among those aged 40 to 64 years, the overweight group had a 50% higher hypertension prevalence rate than the normal-weight group and 100% higher than the underweight group. With each higher degree of blood pressure elevation, relative frequency of hypertension with overweight was larger. Thus this study confirms, in the largest group surveyed to date, similar findings in previous cross-sectional surveys. It is also consistent with data from longitudinal and intervention studies on the importance of overweight in relation to hypertension.

Hypertension screening of 1 million Americans. Community Hypertension Evaluation Clinic (CHEC) program, 1973 through 1975.

During 1973 through 1975, more than 1 million persons were screened in the nationwide Community Hypertension Evaluation Clinic (CHEC) program at 1,171 sites. While those screened were not from defined populations, findings paralleled those of recent surveys of US population samples. First, CHEC confirmed the scope of the problem of elevated blood pressure in the United States. Of those screened, 247 of 1,000 had a diastolic reading of 90 mm Hg or higher; 116 of 1,000 had a reading of 95 mm Hg or greater. Prevalence of elevated blood pressure rose with age up to age 50 years, was higher in blacks than in whites, and was higher in men than in women. Second, CHEC data confirmed the challenge of undetected, untreated, and uncontrolled hypertension. Previously undetected hypertension was present in 27.7% of hypertensive people, detected but untreated in 10.7%, and treated but uncontrolled in 16.7%--totaling 55.1%.
