Issuing from the epidemiological situation of the angiocardiopathies the importance of the factors of risk for the coronary heart disease are emphasized with special consideration of the disturbances of lipometabolism. Essential constituent in the reduction of the factors of risk, particularly obesity, hyperlipoproteinaemia and hypertension, is the change of the habits of nutrition. An increased supply of manifold unsaturated fatty acids, an adequate to the disturbances of lipometabolism type-specific restriction of the cholesterol and carbohydrate intake and a reduction of the saline supply are to be recommended. The importance of measures in the field of health education which should begin already at school age is emphasized.

Obesity, a common disorder causing excess mortality due to the development of cardiovascular disease, hypertension, respiratory illness, and diabetes, is difficult to control by simple dieting techniques. Low calorie foods, which can facilitate newer weight reduction approaches such as behavior modification, often lack adequate palatability due to the absence of carbohydrate or fat. Various low calorie bulking agents that can replace the traditionally used carbohydrates and fats are discussed in terms of caloric value, utility, and regulatory status. Methods of measuring caloric utilization of bulking agents in test animals and humans are evaluated. For fat, no really satisfactory replacement is currently available, although several promising are under development. Dietary fiber sources such as microcrystalline cellulose are receiving considerable attention as flour replacements. While the polyols have many desirable attributes, as sucrose replacements, their caloric utilization values generally prevent a significant caloric reduction when they are used in foods. Several experimental sucrose replacements are described.

The pathogenesis and basic mechanisms of hypertension are not understood. Hypertension is now considered to reflect abnormality in one or more of the biologic systems that regulate flow and resistance. Its complications result from high intra-arterial pressure, and drug treatment substantially lessens these complications. The death rate from hypertension has dropped strikingly. Although current knowledge is not sufficient to develop predictably successful prevention programs, there is growing interest in applying available information. Epidemiologic studies have identified obesity as a major risk factor for hypertension; they have also been interpreted as showing that high dietary sodium intake causes hypertension in industrialized societies. Evidence on the role of obesity seems firm and can provide the basis for prevention programs. The role of sodium intake requires further study.

Essential hypertension is a quantitative abnormality, the pathological effects and risks increasing with the blood pressure level. In Western countries blood pressure rises with age in most individuals, so essential hypertension is more frequent in middle and older age groups. It is likely that an individual's blood pressure level is determined by many interacting factors. These include heredity, which probably acts multifactorially, and many environment influences, including psychological stress and obesity. Specific factors may be of varying importance in different individuals and in different populations. Several physiological mechanisms control the blood pressure level and may be altered in essential hypertension. In early hypertension sympathetic nervous activity is sometimes increased, although in long-standing hypertension this is less marked. Cardiac output may be increased in borderline hypertension but is normal in established hypertension, when total peripheral resistance is increased. Total exchangeable sodium is normal, while the renal pressure-natriuresis balance is altered, so that for a given pressure the hypertension kidney excretes less sodium. In some patients, plasma renin is low, probably as a result of renal adaption to prolonged hypertension. The pathogenic sequence in essential hypertension is uncertain. Increased autonomic activity may cause vasoconstriction in renal and other arterioles and increase cardiac output, leading to a rise in blood pressure. Elevated pressure itself produces structural changes in the resistance vessels, including those of the kidney, which eventually maintain the hypertension even when the initiating stimulus is removed. The way in which heredity and environment influence pathogenic mechanism is also uncertain. Heredity might, for example, influence the autonomic response to stress or the liability to irreversible changes in the resistance vessels or in the kidney. Environmental factors may also increase autonomic activity, enhance vascular reactivity or alter renal function.

Current patterns of health care and its financing need to be improved by the incorporation of cost-effective and health-effective preventive measures. As a stimulus for further development, we propose a Lifetime Health-Monitoring Program that uses clinical and epidemiologic criteria to identify specific health goals and professional services appropriate for 10 different age groups. During infancy, for example, we recommend seven immunizations, tests to detect anemia, hemorrhagic diseases, phenylketonuria and developmental deficiencies, and routine prophylaxis of gonorrheal ophthalmia. In the age group 40 to 59, tests for hypertension, cervical, mammary, and gastrointestinal cancer, and control of obesity and smoking are in order. The cost of such preventive measures. which should not be prohibitive, must be covered by health-insurance programs, whether based on fee-for-service or capitation. The program suggested, by incorporating prevention into day-to-day care, should strengthen the patient-physician relation.

21 young female and 15 young male patients with cerebrovascular insults were examined for risk factors. 14 of the 15 male patients showed clear cut risk factors: obesity, diabetes, hyperlipidemia, arterial hypertension, smoking, thromboses, vitium cordis. 20 of the 21 female patients took oral contraceptives. 60% of the female patients with angiographically confirmed stenoses and occlusion did not show any other risk factor. These results support the hypothesis that oral contraceptives are in themselves a risk factor.

Data from the 1975-1976 National Ambulatory Medical Care Survey conducted by the National Center for Health Statistics were examined retrospectively to determine the extent to which blood pressure was measured during visits to office-based physicians in the conterminous United States. Blood pressure was more often measured for females (especially black) than for males although males (especially black) in certain age groups had a higher prevalence of hypertension and comprised the higher proportion of undiagnosed hypertensives. Blood pressure measurement increased with age, but was rarely measured for those under 15 years of age. Blood pressure was measured about 79 per cent of the time when hypertension was present but only 30 per cent of the time when hypertension was absent. When diseases shown to be frequently concomitant with hypertension were diagnosed in the absence of hypertension, blood pressure checks ranged from 24 per cent of visits diagnosed neuroses to 66 per cent diagnosed obesity. Blood pressure was measured during about 12 per cent of visits for diseases of the nervous system and sense organs as well as diseases of the skin and subcutaneous tissue; 24 per cent of visits for infective and parasitic diseases, diseases of the respiratory system, and mental disorders. Blood pressure was measured most often when diagnoses were in the categories of diseases of the circulatory system and endocrine, nutritional, and metabolic diseases. Opportunities for blood pressure measurement during routine visits did not appear to be fully utilized, nor did some specialists take frequent blood pressure measurements. (Am. J. Public Health 69:19-24, 1979.)

The incidence of ovarian cancer in Rochester, Minnesota over the 40-year period 1935 through 1974 was determined; and risk factors for epithelial ovarian cancer occurring in Rochester from 1945 to 1974 were examined in 116 patients and 464 controls. Among the characteristics studied, only nulliparity was found to be a significant risk factor--relative risk 1.8. Other suspected risk factors--including hypertension, obesity, age at menopause, prior therapeutic pelvic radiation, and prior exposure to exogenous estrogen--were found not to differ significantly between patients and controls. The ovarian cancer patients were found to have a significantly lower frequency of prior hysterectomy and of unilateral oophorectomy than the control group. Thus out data show that hysterectomy, even when one or both ovaries are preserved, is associated with a lower risk of subsequent ovarian cancer.

During a three-month period, March-May 1978, 23 black females were accepted as patients in the obesity program at the model office of the Department of Community Health and Family Practice, College of Medicine, Howard University.An aggregate of 55 visits made by these patients was recorded for the same period.The mean age of the patients was 38.3 years (SD:13.67), and half of the patients were below 40. Nearly 70 percent had a history of obesity in either one or both parents. More than one half had had high blood pressure and 70 percent of the patients had attempted dieting previously. Common snacks taken by the patients were carbohydrate-rich foods.Based on previous medical and dietary history and behavior patterns related to food intake, the patients were prescribed low-calorie or modified high-protein diets. Each patient at the clinic had a program devised individually for her. A team consisting of a physician, nutritionist, and health educator looked for patterns of behavior causing patients to overeat.The mean initial weight of all patients was 218 lb at registration and the weight after seven weeks of follow-up was 213.8 lb.

Computer-assisted static/dynamic renal imaging with [197Hg] chlormerodrin and [99mTc]pertechnetate was evaluated prospectively as a screening test for renovascular hypertension. Results are reported for 51 patients: 33 with benign essential hypertension and 18 with renovascular hypertension, and for 21 normal controls. All patients underwent renal arteriography. Patients with significant obesity, renal insufficiency, or renoparenchymal disease were excluded from this study. Independent visual analyses of renal gamma images and time-activity transit curves identified 17 of the 18 patients with renovascular hypertension; one study was equivocal. There were five equivocal and three false-positive results in the essential hypertension and normal controls groups. The sensitivity of the method was 94% and the specificity 85%. Since the prevalence of the renovascular subset of hypertension is approximately 5%, the predictive value is only 25%. Inclusion of computer-generated data did not improve this result. Accordingly, this method is not recommended as a primary screening test for renovascular hypertension.
