Association between prenatal polychlorinated biphenyl exposure and obesity development at ages 5 and 7y: a prospective cohort study of 656 children from the Faroe Islands

submitted by: jltp@mac.com
Abstract Background: Chemicals with endocrine-disrupting abilities may act as obesogens and interfere with the body's natural weight-control mechanisms, especially if exposure occurs during prenatal life. Objective: We examined the association between prenatal exposure to polychlorinated biphenyls (PCBs) and p,p?-dichlorodiphenyldichloroethylene (DDE) and subsequent obesity at 5 and 7 y of age. Design: From 1997 to 2000, 656 pregnant Faroese women were recruited. PCB and DDE were...

Evidence-Based Strategies in Weight Loss Mobile Apps

submitted by: spagoto
Background: Physicians have limited time for weight-loss counseling, and there is a lack of resources to which they can refer patients for assistance with weight loss. Weight-loss mobile applications (apps) have the potential to be a helpful tool, but the extent to which they include the behavioral strategies included in evidence-based interventions is unknown. Purpose: The primary aims of the study were to determine the degree to which commercial weightloss mobile apps include the...

Association between water consumption and body weight outcomes: a systematic review

submitted by: Rebecca
BACKGROUND Drinking water is often applied as a dietary means for weight loss and overweight/obesity prevention, but no evidence-based recommendation exists for this indication. OBJECTIVE We summarized the existing evidence on the association between water consumption and body weight outcomes in adults of any body weight status. DESIGN In a systematic review, we retrieved studies from 4 electronic databases (MEDLINE, EMBASE, CINAHL, and COCHRANE), cross-references by PubMed functions...

Weight-loss diets in people with type 2 diabetes and renal disease: a randomized controlled trial of the effect of different dietary protein amounts

submitted by: Peter Clifton
ABSTRACT Background: Higher-protein weight-loss diets (defined as >25% of energy as protein) are not recommended for individuals with type 2 diabetes because of their potential adverse effect on renal function. Objective: We aimed to examine the effect of such diets on renal function over 12 mo in people with type 2 diabetes and early renal disease. Design: Overweight and obese people with type 2 diabetes were screened to identify those with an albumin:creatinine ratio from 3 to...

Factors predicting overweight in US kindergarteners

submitted by: glflor
BACKGROUND: Childhood overweight is a substantial public-health problem, but little is known about predictors of early childhood overweight. OBJECTIVE: We aimed to identify factors-alone and in combination-that predict kindergarten overweight. DESIGN: We analyzed nationally representative data from the Early Childhood Longitudinal Study-Birth Cohort, a longitudinal cohort study of 6800 children followed from birth through kindergarten. Multivariable logistic regression and recursive...

Weight loss, weight maintenance, and adaptive thermogenesis

submitted by: stefancamps
Background: Diet-induced weight loss is accompanied by adaptive thermogenesis, ie, a disproportional or greater than expected reduction of resting metabolic rate (RMR). Objective: The aim of this study was to investigate whether adaptive thermogenesis is sustained during weight maintenance after weight loss. Design: Subjects were 22 men and 69 women [mean 6 SD age: 40 6 9 y; body mass index (BMI; in kg/m2): 31.9 6 3.0]. They followed a very-low-energy diet for 8 wk, followed by a...

Beneficial effects of a higher-protein breakfast on the appetitive, hormonal, and neural signals controlling energy intake regulation in overweight/obese, “breakfast-skipping,” late-adolescent girls

submitted by: hurstn
Background: Breakfast skipping is a common dietary habit practiced among adolescents and is strongly associated with obesity. Objective: The objective was to examine whether a high-protein (HP) compared with a normal-protein (NP) breakfast leads to daily improvements in appetite, satiety, food motivation and reward, and evening snacking in overweight or obese breakfast-skipping girls. Design: A randomized crossover design was incorporated in which 20 girls [mean 6 SEM age: 19 6 1 y;...

Correcting vitamin D insufficiency improves insulin sensitivity in obese adolescents: A randomized controlled trial

submitted by: petersonca
Background: Obese adolescents are at a greater risk for vitamin D deficiency because the vitamin is thought to be sequestered by excess adipose tissue. Poor vitamin D status has been associated with a higher prevalence of the metabolic syndrome and/or type 2 diabetes in both adults and adolescents. Objective: To determine in obese adolescents the efficacy and safety of 4000 IU/day of vitamin D3; and if subsequent increased circulating concentrations of 25 hydroxyvitamin D [(25(OH)D] are...

Vitamin D supplementation and calcium absorption during caloric restriction: a randomized double blind trial

submitted by: shapses
Background: Weight loss (WL) is associated with a decrease in calcium absorption and may be one mechanism that induces bone loss with weight reduction. Objective: Because vitamin D supplementation has been shown to increase true fractional calcium absorption (TFCA), the goal of this study was to examine the effect of vitamin D during WL or weight maintenance (WM). Design: A randomized, placebo-controlled, double-blind 6-wk study was conducted in 82 postmenopausal women [BMI (in kg/...

Being Overweight or Obese Is Associated with Lower Prevalence of Anemia among Colombian Women of Reproductive Age

submitted by: kasiek
Overweight and micronutrient deficiencies have manifested in the same individuals. This study investigated the association among iron deficiency (ID), anemia, and weight status among nonpregnant Colombian females aged 13-49 y (n = 3267). Data from the 2005 National Survey of the Nutrition Situation were used. The prevalence of ID (plasma ferritin <12.0 ?g/L; individuals with CRP >0.012 g/L excluded) and anemia (altitude-adjusted hemoglobin <120 g/L) was estimated separately. The...
