Summary Background Infant adiposity better predicts childhood obesity/metabolic risk than weight, but technical challenges fuel controversy over the accuracy of adiposity estimates. Objective We prospectively measured adiposity (%fat) in term newborns (NB) at 2 weeks (n = 41) and 1 year (n = 30). Methods %fat was measured by dual X-ray absorptiometry (DXA), PEAPOD and skin-folds (SF). DXAs were analyzed using Hologic Apex software 3.2(DXAv1) and a new version 5.5.2(DXAv2). Results NB %fat by DXA...

Context: Type 2 diabetes (T2D) is reduced in postmenopausal women randomized to estrogen-based hormone therapy (HT) compared with placebo. Insulin sensitivity is a key determinant of T2D risk and overall cardiometabolic health, and studies indicate that estradiol (E2) directly impacts insulin action. Objective: We hypothesized that the timing of E2 administration after menopause is an important determinant of its effect on insulin action. Design: We performed a randomized, crossover, placebo-con...

Summary What is already known about this subject Type 2 diabetes is increasing in youth, but little is known about the underlying pathophysiology. Elevated fasting free fatty acids and failure of insulin to suppress lipolysis are well described in adults. Small studies suggest that obese youth with and without type 2 diabetes have impaired suppression of lipolysis, but there are little data on associated factors. What this study adds Assessment of insulin suppression of lipolysis in a larger coh...

The aim of this study was to determine whether estrogen and/or raloxifene help to conserve bone mineral density (BMD) during moderate weight loss. Postmenopausal women (n = 68) participated in a 6-month weight loss program that consisted primarily of supervised exercise training. Another 26 women were studied over 6 months of weight stability. All participants were randomized to three treatment arms: placebo, raloxifene (60 mg/d), or hormone therapy (HT; conjugated estrogens, 0.625 mg/d; trimont...

There is a lack of knowledge regarding the effects of estrogens on physical performance. This is related, in part, to the challenge of isolating the effects of estrogens from those of progestins, because levels of both hormones fluctuate across the menstrual cycle, both decline during the menopausal transition, and the administration oh hormones to hypogonadal women typically involves a combination of estrogens and progestins. Some research findings suggest that fluctuations in estrogen levels a...

To test the hypothesis that estrogens alter insulin action, we evaluated the effects of intravenous conjugated estrogens (CE) on insulin-stimulated steady-state glucose infusion rate (SSGIR) and suppression of plasma glycerol in postmenopausal women (mean ± SD; 56 ± 4 yr; n = 12) not using hormone replacement. SSGIR and glycerol were measured during a two-stage (8 and 40 mU · m-2 · min-1) hyperinsulinemic euglycemic clamp on 2 days, with or without a 2.5-mg intravenous CE bolus. Serum estradiol ...

The aim of this study was to determine whether trunk fat mass, measured by dual-energy X-ray absorptiometry (DEXA), is predictive of insulin resistance and dyslipidemia, independently of arm and leg fat mass, in postmenopausal women. Total and regional body composition was measured by DEXA in 166 healthy, postmenopausal women (66 ± 4 yr). Four primary markers of insulin resistance and dyslipidemia were assessed: 1) area under the curve for the insulin (INSAUC) response to an oral glucose toleran...
