Abstract Background Recent studies suggested an inverse association between exposures to perfluoroalkyl substances (PFASs) and bone mineral density (BMD). Whether exposures to PFASs are also associated with changes in BMD has not been examined. Methods Five major PFASs (perfluorooctanesulfonic acid, PFOS; perfluorooctanoic acid, PFOA; perfluorohexanesulfonic acid, PFHxS; perfluorononanoic acid, PFNA; perfluorodecanoic acid, PFDA) and BMD (g/cm2) at six bone sites (spine, total hip, femoral neck,...

Purpose of Review This paper reviews the genetic and non-genetic factors that provided predictions of, or were associated with, weight loss and other metabolic changes in the POUNDS Lost clinical trial of weight loss. This trial randomized 811 individuals who were overweight or obese to one of four diets that contained either 15% or 25% protein and 20% or 40% fat in a 2 × 2 factorial design. A standard behavioral weight loss program was available for all participants who were followed for 2 year...

OBJECTIVE Regression from prediabetes to normal glucose regulation (NGR) was associated with reduced incidence of diabetes by 56% over 10 years in participants in the Diabetes Prevention Program Outcomes Study (DPPOS). In an observational analysis, we examined whether regression to NGR also reduced risk for microvascular disease (MVD). RESEARCH DESIGN AND METHODS Generalized estimating equations were used to examine the prevalence of aggregate MVD at DPPOS year 11 in people who regressed to NGR ...

OBJECTIVE Type 2 diabetes is related to obesity and altered bone health, and both are affected by gut microbiota. We examined associations of weight loss diet–induced changes in a gut microbiota–related metabolite trimethylamine N-oxide (TMAO), and its precursors (choline and L-carnitine), with changes in bone mineral density (BMD) considering diabetes-related factors. RESEARCH DESIGN AND METHODS In the 2-year Preventing Overweight Using Novel Dietary Strategies trial (POUNDS Lost), 264 overweig...

Background: Recent evidence has related high levels of plasma branch-chained amino acids (BCAAs) with liver and visceral fat. We examined the associations of plasma BCAAs with liver fat and abdominal fat distribution and assessed the potential modification of weight-loss diet interventions on these relations. Methods: The current study included 184 participants with available data on plasma BCAAs, hepatic fat and abdominal fat distribution over 2 years, who were randomly assigned to 1 of 4 diets...

Purpose A common variant of the melatonin receptor 1B (MTNR1B) gene has been related to increased signaling of melatonin, a hormone previously associated with body fatness mainly through effects on energy metabolism. We examined whether the MTNR1B variant affects changes of body fatness and composition in response to a dietary weight loss intervention.
