Filter by:This randomized controlled trial is designed to test the feasibility and efficacy of a novel 10-week mindfulness-based intervention (MBI) on weight maintenance as well as behavioral and psychosocial outcomes in patients who have undergone bariatric surgery. Primary hypothesis: Bariatric patients who have stopped losing weight (< 5 lbs weight loss in past month) 1-5 years post-surgery will be willing to participate in this 10-week intervention. The investigators expect a high adherence rate (>70%) and no issues with meeting recruitment goals. Secondary hypotheses: Patients assigned to the MBI will show greater improvement in a) weight control (defined by differences in body weight between baseline and follow-up); b) eating behaviors (binge eating, emotional eating); and c) psychosocial measures (quality of life, depression, perceived stress, eating self-efficacy, coping ability) than a standard lifestyle intervention (1 hr lifestyle counseling). Patients assigned to the MBI intervention will show greater improvement in biomarkers of stress and inflammation [salivary cortisol, high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha)] as compared with a standard lifestyle intervention. Food-related attentional bias as measured by the food-related Stroop task will be differentially affected among patients assigned to the MBI as compared with the intensive lifestyle intervention and standard lifestyle intervention.
The primary purpose of this study is to assess the responses of pregnant women and their social network to six videos about health in pregnancy. Our goal is to assess a) acceptability and b) understanding of core messages about healthy eating, exercise and weight gain during pregnancy. We will also assess c) non-clinical sources of health information during pregnancy.
Marrow adipocytes have been identified as a component of the bone marrow micro-environment. Evidence exists suggesting that marrow fat plays an important physiologic role in both bone mineral and energy metabolism in humans. The investigators will study the effects of acute weight gain and acute nutritional deprivation on energy homeostasis and bone mineral metabolism by examining marrow adiposity, peripheral fat depots and bone microarchitecture. The study will include two ten day inpatient study visits. Participants will eat a high calorie diet for 10 days, followed by a 13-18 day stabilization period at home, and then return for a ten day fast.
The purpose of this research study is to evaluate the effect of a Facebook-delivered weight-gain prevention program versus a Facebook-delivered program with general women's health information.
South Asians have a much higher risk of diabetes compared to Europeans and investigators don't know why this is. Investigators think that South Asians' capacity to store fat safely under the skin is lower than Europeans, so they start to store fat around internal organs and in liver and muscle, and at lower body weights than Europeans. These increased levels of internal fat storage are thought to increase risk of diabetes. The purpose of the study therefore is to investigate whether there are differences with weight gain and weight loss in fat storage, fat cell function and metabolic risk factors, in South Asians compared with Europeans. Investigators will compare South Asian and European men at the start of the study, after they have gained about 7% body weight, and again after they have lost 7-15% body weight (from peak weight) to see how gaining and losing weight affects fat storage within the body and the function of fat cells. Investigators will also assess the effect of weight gain and weight loss on metabolism, fitness and risk factors for diabetes and heart disease.
This will be an open label clinical trial with all subjects receiving both lorcaserin and varenicline with a primary aim of reducing post cessation weight gain.
This research study is aimed at the prevention of excessive weight gain in female military dependents at high risk for adult obesity. The purpose of this study is to determine whether reducing Loss of Control (LOC) eating and associated indicators through use of interpersonal psychotherapy (IPT) will be feasible and acceptable to female adolescent dependents who report such behaviors. Moreover, patterns in the data will be examined to assess whether IPT influences body weight gain trajectories and prevent worsening disordered eating and metabolic functioning among female military dependents at heightened risk for unhealthy weight gain.
Examining the effect of daily self-weighing on the ability of student to prevent from gaining weight during their four years at Cornell.
Schizophrenia and bipolar disorders are major public health problems. The second generation anti-psychotic drugs have efficacy for both positive and negative symptoms and a favorable risk profile as far as movement disorders. However, these drugs are associated with clinically significant weight gain and metabolic effects. The underlying mechanisms of these side effects are unclear, however in our preliminary studies with schizophrenic patients on atypical anti-psychotic drugs, we found that weight gain and vitamin D deficiency was present in about 50% of this population. Given the considerable heterogeneity among the patients on atypical anti-psychotics and potential for weight gain in vitamin D-deficient states, we propose that patients with schizophrenia who gain weight on atypical antipsychotic medications are vitamin D-deficient. This hypothesis will be tested in patients with schizophrenia receiving second-generation anti-psychotic drugs for a minimum duration of 4 months. Specific Aim: We predict that the patients with schizophrenia, who gain weight with antipsychotic treatment, are vitamin D-deficient compared to the patients who do not gain weight. We will examine circulating levels of serum 25(OH)D, mRNA transcripts and protein expression of vitamin D receptor (VDR) and the enzymes, CYP24A and CYP27B, in the white blood cells of the subjects and correlate with BMI and the blood levels of leptin and adiponectin.
Excessive weight gain during pregnancy, particularly in overweight and obese women, predisposes to adverse perinatal outcomes and has long term effects on maternal and neonatal health. With an inverse relationship between socioeconomic status and obesity, significant health disparities exist between obese and normal weight women. The Institute of Medicine (IOM) recently revised its gestational weight gain recommendations, targeted to pregravid body mass index (BMI), to minimize pregnancy complications. However, these recommendations are based on cross sectional observational studies and neither the ideal method to achieve weight gain goals nor whether perinatal outcome is optimized with active management of weight gain is known. The investigators propose to investigate a behavioral incentive-based intervention to improve compliance with IOM weight gain recommendations during pregnancy in low-income overweight and obese women. The investigators will evaluate if 1) gestational weight gain can be reliably targeted to the IOM recommendations and 2) active weight gain management during pregnancy improves perinatal outcomes. Two study groups will be compared in a prospective randomized trial; 1) those receiving standard obstetrical care and 2) those receiving behavioral weight management counseling plus financial incentives for achieving weight gain goals. The main outcome measure will be the percentage of women gaining within the IOM recommendations based on prepregnancy BMI. Secondary outcomes evaluated will include fetal growth and body composition changes, birth weight and the rate of cesarean delivery. The investigators hypothesize that 1) the behavioral intervention with incentives will result in greater compliance to IOM guidelines for gestational weight gain than standard care and 2) targeting weight gain to the IOM guidelines will lead to a reduction in the rates of fetal macrosomia and cesarean delivery. Finally, cost effectiveness of treatment conditions will be examined. This intervention, if efficacious and cost-effective, has the potential to improve compliance with gestational weight gain guidelines, optimize perinatal outcomes, and reduce health disparities.
