Associations Of Resting Heart Rate With Concentrations Of Lipoprotein Subfractions In Sedentary Men, Paul T. Williams, William L. Haskell, Karen M. Vranizan, Steven N. Blair, Ronald M. Krauss, Robert Superko, John J. Albers, Barbara Frey-Hewitt, Peter D. Wood Mar 1985

Associations Of Resting Heart Rate With Concentrations Of Lipoprotein Subfractions In Sedentary Men, Paul T. Williams, William L. Haskell, Karen M. Vranizan, Steven N. Blair, Ronald M. Krauss, Robert Superko, John J. Albers, Barbara Frey-Hewitt, Peter D. Wood

In major prospective studies it has been reported that high heart rate at rest predicts the development of coronary heart disease (CHD) or cardiovascular disease (CVD) in men, but the mechanisms producing these relationships are unknown. Since lipoprotein levels contribute strongly to the risk of CHD and CVD, we examined the relationship of resting heart rate to plasma concentrations of high-density (HDL), low-density (LDL), and very low-density (VLDL) lipoproteins, apolipoprotein (apo) A-I and A-II, and serum concentrations of lipoprotein subfractions in 81 men to determine if atherogenic lipoproteins could potentially induce the reported association of heart rate with development of …

Effects Of Water Quality And Water Quantity On Nutritional Status: Findings From A South Indian Community, James R. Hébert Jan 1985

Effects Of Water Quality And Water Quantity On Nutritional Status: Findings From A South Indian Community, James R. Hébert

Faculty Publications

Quantitative assessments of the relative effects on health of various aspects of water supply are virtually absent from the literature. Despite the lack of information, resources are being allocated throughout the developing world, for projects related to water and sanitation. The present study was designed specifically to overcome many of the methodological problems that other researchers have faced. Data were collected concerning the nutritional status of 627 children in three urban communities in South India. Information was also collected on water quality, water quantity, household sanitation, socioeconomic conditions, and housing. A statistical technique is presented that allows for controlling potential …

Comparison Of Haitian Children In A Nutrition Intervention Programme With Children In The Haitian National Nutrition Survey, G. G. Berggren, James R. Hébert, C. M. Waternaux Jan 1985

Comparison Of Haitian Children In A Nutrition Intervention Programme With Children In The Haitian National Nutrition Survey, G. G. Berggren, James R. Hébert, C. M. Waternaux

Faculty Publications

Weight-for-height and height-for-age data were compared for preschool-age Haitian children enrolled in a community health and nutrition intervention programme and children measured in the Haiti national nutrition survey of 1978. Cross-sections of the longitudinal data of the intervention programme corresponding to the season when the national survey was conducted (May to September) were chosen for the three years of available programme data (1969, 1970, 1971). Significantly less stunting was found in children in the 1970 and 1971 intervention group than in the children covered by the national survey. Tests of trend also showed that the height (or length) status of …

Association Between Coronary Heart Disease Risk Factors And Physical Fitness In Healthy Adult Women, Larry W. Gibbons, Steven N. Blair, Kenneth H. Cooper, Mike Smith May 1983

Association Between Coronary Heart Disease Risk Factors And Physical Fitness In Healthy Adult Women, Larry W. Gibbons, Steven N. Blair, Kenneth H. Cooper, Mike Smith

Faculty Publications

We examined associations between physical fitness and risk factors for coronary heart disease in healthy women ages 18-65 years. Physical fitness was objectively determined by the duration of a maximal treadmill exercise test. Six physical fitness categories (very poor to superior), specific within 10-year age increments, were established. Mean risk factor levels varied across categories, but so did potential confounders such as age and weight. Multiple linear regression modeling was used to control for the effects of age, weight and year of exam on coronary risk factors. After adjustment, physical fitness was independently associated with triglycerides (p < 0.001), high-density lipoprotein cholesterol (HDL-C) (p less …

Does Weight Loss Cause The Exercise-Induced Increase In Plasma High Density Lipoproteins?, Paul T. Williams, Peter D. Wood, Ronald M. Krauss, William L. Haskell, Karen M. Vranizan, Steven N. Blair, Richard Terry, John W. Farquhar May 1983

Does Weight Loss Cause The Exercise-Induced Increase In Plasma High Density Lipoproteins?, Paul T. Williams, Peter D. Wood, Ronald M. Krauss, William L. Haskell, Karen M. Vranizan, Steven N. Blair, Richard Terry, John W. Farquhar

Faculty Publications

Studies showing an increase in plasma concentration of high density lipoprotein cholesterol (HDL-C) with moderate exercise have usually rejected the role of body weight change in the HDL-C raising process, ostensibly because the amount of weight lost has been negligible. To investigate HDL-C changes more thoroughly, we followed initially sedentary middle-aged men randomly assigned to either a moderate running (N=36) or a sedentary control (N=28) group for one year. Among runners, one-year changes in plasma HDL-C concentrations correlated strongly with their body weight changes (r = -0.53, P < 0.001). Curve-fitting procedures and regression analysis suggested that processes associated with weight change produce much of the plasma HDL-C changes induced by moderate exercise and that changes in HDL-C concentration predominantly reflect changes in the reputedly anti-atherogenic HDL2 sub-component. Further, the interaction between weight change and plasma HDL-C concentration was significantly different (P

Hormonal Regulation Of Lipolysis And Phosphorylase Activity In Human Fat Cells, Jay Moskowitz, John N. Fain May 1969

Hormonal Regulation Of Lipolysis And Phosphorylase Activity In Human Fat Cells, Jay Moskowitz, John N. Fain

Faculty Publications

A B S TR A C T Prostaglandin E1 (PGE1) at a concentration of 1 ng/ml antagonized theophylline, and norepinephrine induced release of glycerol and free fatty acids (FFA) in human fat cell preparations. Insulin at higher doses also inhibited theophylline-stimulated lipolysis. The N6-2-O'dibutyryl derivative of cyclic adenosine monophosphate (DCAMP) stimulated lipolysis. Prostaglandin E1 did not significantly inhibit the lipid mobilizing effects of DCAMP. Changes in glycogen phosphorylase activity after treatment with theophylline, norepinephrine, DCAMP, and PGE1 paralleled those of lipolysis. These results suggest that in man as in experimental animals lipolysis …
