Racial patterns of heart rate in an employed adult population.

This study explored racial patterns of heart rate in a large population of employed Chicagoans: 39,665 adults screened in Chicago firms between late 1967 and early 1973. Of these, 30,876 were white or black adults age 18--64 with complete data, and not on drug therapy for hypertension. Mean heart rates of young black men and women were significantly lower than mean heart rates of young white men and women. This difference was not present for the age groups 35 and older. The difference was present in both smokers and non-smokers; in normotensives and in persons with elevated blood pressure; and could not be explained by differences in relative body weight. The difference persisted after simultaneous adjustment for differences in the mean values of systolic blood pressure, relative weight, serum cholesterol, post-loaded plasma glucose, and number of cigarettes smoked per day.

Uric acid: a risk factor for coronary heart disease?

The association between serum uric acid and the prevalence of ECG abnormalities was analyzed for 24.997 employed men and women, white and black, age 18--64 years, from the Chicago Heart Association (CHA) Detection Project in Industry. In addition, the relationships between uric acid and 5-year mortality from all causes, from cardiovascular diseases (CVD), and from coronary heart disease (CHD) were analyzed for 7804 white men and women age 45--64 years from this study and 967 white men age 44--63 years from the Chicago People's Gas Company Study. For men, the association between uric acid and the prevalence of ECG abnormalities and with mortality appear to be secondary to associations between uric acid and other risk factors. For women, however, the associations could not be explained by other risk factors.

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.

Dietary and serum lipids in the multifactorial etiology of atherosclerosis.

The incidence of severe atherosclerosis is ascribable to a multiplicity of risk factors, cardinal among which is the serum cholesterol concentration. The dietary fat content, the serum cholesterol level, and the incidence of atherosclerosis are clearly correlated in different countries and in population cohorts. Within a population, the serum cholesterol level is a major independent risk factor for premature atherosclerotic disease.

A hypertension control program based on the workplace. Report on the Chicago Center.

In several large Chicago companies and institutions, workplace screening of 7,151 persons yielded 833 suspect hypertensives. Of these, 91% attended a follow-up verification visit, where for 513 persons high diastolic pressure was confirmed. One-half of these persons were referred to their physicians for treatment and one-half were randomly assigned to be treated directly by HDFP, in a step-wise pharmacologic regimen to normalize diastolic pressure. Of the 257 persons assigned to program treatment, 94% accepted such treatment, and over 90% of these still living in the community were active participants at one year. Average diastolic pressure of these active participants was 83.1 mm Hg at one year, compared to 102.6 at first screen and 98.8 at the second confirmatory screening. A strenuous effort has been made to reduce or eliminate obstacles to treatment, including lack of understanding of the need for long-term therapy, cost barriers and barriers of inconvenience of treatment. The medical team conducting the program combined physicians with nonphysician therapist-health counselors, plus "outreach" staff, to maximize program adherence. Preliminary experiences in the Chicago Center of the Hypertension Detection and Follow-Up Program (HDFP) give encouraging evidence that the workplace is a useful base for successful hypertension control efforts.

George Lyman Duff Memorial Lecture. Lifestyles, major risk factors, proof and public policy.

In this report major risk factors in coronary heart disease (CHD) are reviewed, with particular emphasis on the role of nutrition. International and national epidemiologic data indicate that reducing or eliminating certain risk factors (e.g., a diet high in cholesterol and saturated fats) may reduce the risk of premature CHD. Most trends indicate that many Americans are more concerned about diet for health reasons. Preventive measures for CHD are also discussed.
