Active clinical trials for "Weight Loss"

Approximately 8 million American women suffer from osteoporosis, and one out of every two women over the age of 50 will have an osteoporotic-related fracture in their lifetime (42). While epidemiological studies suggest that pregnancy and lactation are not associated with risk of fractures later in life, these studies did not control for site-specific decrements in bone mineral density (BMD). In addition, 55% of American women between the ages of 20 to 39 are overweight (14). Excess weight retention after pregnancy increases a woman's risk for developing a chronic disease later in life (44). There is a paucity of research on exercise and dietary interventions in postpartum lactating women aimed at promotion of bone health and weight loss. The goal of this study is to promote long-term lifestyle changes through a home based strength training, aerobic, and nutrition intervention targeting overweight lactating women. The objective is to attenuate lactation-induced bone loss and promote weight loss. We hypothesize that the intervention group will lose a greater amount of fat mass while preserving lean mass and bone mineral mass and increase levels of anabolic hormones through diet and exercise compared to the minimal care group. Additionally, the acquisition of such knowledge is unique since no other studies have measured growth hormone and insulin-like growth factor-1 in lactating women with respect to bone and exercise. This intervention will encourage breastfeeding, weight loss and an increase in bone density resulting in healthy infants and mothers. The proposed research is the first to examine the effects of a resistance exercise and weight loss intervention on attenuation of lactation-induced bone loss in overweight women. To our knowledge, this is the first study to use MyPyramid for Menu Planner for Moms for dietary counseling using the total diet approach. The expected outcomes are the intervention group will lose weight while preserving lean body mass, bone mineral mass and increase cardiovascular fitness and strength compared to the minimal care group. Additionally, the exercise group will improve the overall quality of their diet using internet based technology. An increase in activity and promotion of weight loss through a modest reduction in calories may lead to overall improvement of the mother's bone and health status later in life.

High levels of mannose-binding lectin (MBL), an activator of a part of the immune system called the complement system, have been associated with increased mortality and risk of early signs of kidney damage in patients with type 2 diabetes. The effect of weight loss and changes in insulin resistance on MBL levels have been poorly elucidated. This study includes 36 nondiabetic obese subjects, who will receive a very low- calorie diet (VLCD) of 800 kcal/day for 8 weeks. Fasting blood samples will be obtained at baseline and after 8 weeks of VLCD and concentrations of MBL, glucose and insulin will be measured. Insulin resistance is assessed using the HOMA-IR method.

This 12-month randomized controlled trial, sponsored by NIH/NCI, aims to reduce BMI in obese adolescents (ages 11 -13) by intervening on physical activity and nutrition behaviors within primary care settings. PACE-PC is a theory-based stepped care program that enables pediatricians and primary care providers to intervene with obese adolescents to improve their anthropometric, metabolic, physiological, behavioral, and quality of life outcomes over a one-year period. The program integrates clinician counseling, health educator counseling, and phone and mail contact. It supports tailoring to the needs of obese adolescents and family members and promotes improved diet and physical activity behaviors, weight loss, and ultimately weight loss maintenance. Participants will be randomly assigned to the Enhanced Usual Care or the PACE-PC stepped care condition. The Enhanced Standard Care condition includes an initial visit and counseling by a physician, 3 visits with a health educator, and materials on how to improve weight related behaviors. The PACE-PC Stepped Care condition includes 3 steps (each lasting 4 months), with the first step being the most intensive: Step 1 includes: a physician visit, monthly health educator visits, biweekly phone counseling, and weekly dissemination of nutrition and physical activity information Step 2 includes: a health educator visits every other month, biweekly phone counseling, and weekly dissemination of nutrition and physical activity information Step 3 includes: monthly phone counseling and weekly dissemination of nutrition and physical activity information Participants randomized to the PACE-PC condition will be enrolled in Step 1 (the most intensive) for the first 4 months. Depending upon response at the end of Step 1, for the next 4 months adolescents will be triaged to Step 2 (less intensive) or will repeat Step 1. At 8 months, again based upon treatment response, triage will occur to either Step 3 (least intensive) or repetition of the previous step.

The objective of the present study was to investigate the acute and sub-chronic effect of a supplement containing green tea extract, capsaisin, caffeine, tyrosine and calcium or placebo taken t.i.d on thermogenesis, body fat loss, and fecal fat excretion. Furthermore, if a 8-week supplementation could prevent weight-regain after initial 4-week weight loss.

The purpose of this study is to determine whether robotic assistance can help facilitate adherence, engagement, and weight loss in participants enrolled in a behavioral weight loss program. All participants will be enrolled in the same Web-based weight loss program and take part in "robotic assistance sessions" either early or late in the five-week study. These robotic assistance sessions involve speaking one on one with a robot about diet-related progress.

The study is a nationwide, register-based cohort survey study. The objective of this study is to investigate whether weight change is associated with the incidence of persistent postoperative pain following total hip arthroplasty and knee arthroplasty across non-obese and obese and patients.

Clinical trial participation has historically been heavily biased toward specific demographics. Several people will be invited to enroll in this study so that it may collect a variety of data about gastric bypass clinical trial experiences and identify barriers to participation as well as the causes of participants' failure or withdrawal. The information collected from this study can be used to improve patient experience and outcomes for future patients and an opportunity to contribute to the advancement of medical knowledge and treatments for gastric bypass.

This study seeks to assess how different incentive strategies may reduce the initial attrition gap when implementing weight management in a primary care clinic predominantly serving African American patients. This will be done through an innovative research-practice partnership involving primary care, research expertise, and a small business. Participants will be randomly assigned to one of four financial incentive conditions respectively tied to: weight loss, weigh-ins, weigh-ins and weight-loss, and incentive choice. Participants will be followed for 3 and 6 months to assess program reach, sustaining the reach after initial weigh-in, and weight loss outcomes based on records on participant enrollment and subsequent weigh-ins automatically collected through a kiosk at the clinic.

Excess skin on the abdomen is a common problem for many individuals after massive weight loss. The surgical procedure of abdominoplasty is intended to remove excess skin and improve the shape of the torso in abdomen, in order to address issues such as skin fold eczema, difficulties finding clothing, and psychosocial issues. The investigators will conduct a randomized, controlled trial where individuals with excess skin on the abdomen will be randomized to either standard abdominoplasty or abdominoplasty in combination with liposuction. The investigators will examine the rate of complications, and the functional and aesthetical outcomes of the two methods.

This project is studying whether patients who use MyFitnessPal as an aid to weight loss have more success than patients who are only given traditional medical guidance from the patient's physician.
