To evaluate whether the use of noncontraceptive estrogen influenced the incidence of first myocardial infarction in women.
To assess the association of immunogenetic factors with onset of coronary heart disease and the interrelationship of these factors with standard coronary heart disease risk factors.
To further define the linkage of the Apo A-I gene polymorphism to genetic high density lipoprotein (HDL) deficiency and premature coronary artery disease. Also, to utilize this gene marker to define the prevalence of genetic HDL deficiency in patients with premature coronary disease and to determine the relative risk of premature coronary disease associated with the Apo A-I gene polymorphism.
To test the hypothesis that increased risk of coronary heart disease, stroke, peripheral vascular disease, and cancer is related to diets high in saturated fat, animal protein, and hydrogenated vegetable oil, and low in polyunsaturated fat, fiber, vitamins A, C, and E, calcium, selenium, and chromium.
To correlate dietary factors and changes in pressor substances, including aldosterone and norepinephrine, with blood pressure during growth and sexual development from childhood through adolescence.
To determine the distribution of left ventricular hypertrophy and retinal vascular abnormalities in children and adolescents with essential hypertension; to evaluate potential risk factors and the time sequence for the development of these end-organ complications in this population.
To document the patterns of influence or socialization from parents to children in regard to the transmission of cardiovascular disease risk related behaviors such as diet and physical activity.
In the first study, to identify children at high and low risk for cardiovascular disease and study their nutritional and physical activity behaviors as they relate to cardiovascular disease. In the second study, to make yearly assessments over a four year period of diet and physical activity among children and their parents. The initial effort redefined and retested methods to collect data on dietary intake and activity levels of young children.
To study weight maintenance behaviors, weight trends, and behavioral differences between healthy, normal weight and mildly obese adults.
