Journal ArticleDOI
Low-fat dietary pattern and weight change over 7 years: the Women's Health Initiative Dietary Modification Trial.
Barbara V. Howard,JoAnn E. Manson,Marcia L. Stefanick,Shirley A.A. Beresford,Gail C. Frank,Bobette Jones,Rebecca J. Rodabough,Linda Snetselaar,Cynthia A. Thomson,Lesley F. Tinker,Mara Z. Vitolins,Ross L. Prentice +11 more
TL;DR: A low-fat eating pattern does not result in weight gain in postmenopausal women and a similar but lesser trend was observed with increases in vegetable and fruit servings, and a nonsignificant trend toward weight loss occurred with increasing intake of fiber.
Journal ArticleDOI
Racial differences in the relation between blood pressure and insulin resistance.
Mohammed F. Saad,Stephen Lillioja,B. L. Nyomba,Castillo C,R T Ferraro,De Gregorio M,Eric Ravussin,W. C. Knowler,Peter H. Bennett,Barbara V. Howard +9 more
TL;DR: The relations between insulinemia, insulin resistance, and blood pressure differ among racial groups and may be mediated by mechanisms active in whites, but not in Pima Indians or blacks.
Journal ArticleDOI
Insulin resistance, the metabolic syndrome, and risk of incident cardiovascular disease in nondiabetic american indians: the Strong Heart Study.
Helaine E. Resnick,Kristina L. Jones,Giacomo Ruotolo,Arvind K. Jain,Jeffrey A. Henderson,Weiquan Lu,Barbara V. Howard +6 more
TL;DR: Among nondiabetic AI in the Strong Heart Study, HOMA-IR and MS both predict diabetes, but neither predicts CVD independently of other established CVD risk factors.
Journal ArticleDOI
Assessment of QT interval and QT dispersion for prediction of all-cause and cardiovascular mortality in American Indians: The Strong Heart Study.
Peter M. Okin,Richard B. Devereux,Barbara V. Howard,Richard R. Fabsitz,Elisa T. Lee,Thomas K. Welty +5 more
TL;DR: These findings support the value of computerized measurements of QTc and QTD in noninvasive risk stratification and suggest that these surface ECG variables may reflect different underlying abnormalities of ventricular repolarization.
Journal ArticleDOI
Antioxidant Vitamin Supplements and Cardiovascular Disease
Penny M. Kris-Etherton,Alice H. Lichtenstein,Barbara V. Howard,Daniel Steinberg,Joseph L. Witztum +4 more
TL;DR: Findings have been supported by in vitro studies that have established a role of oxidative processes in the development of the atherosclerotic plaque and a low energy density to promote weight control and a high nutrient density to meet all nutrient needs.
