Active clinical trials for "Overweight"

Dietary manipulation is proving to be an effective lifestyle strategy to combat the obesity epidemic. Increased dietary protein is one effective strategy. For example, increased whey protein ingestion with and without exercise training is associated with enhanced weight loss, body composition and subjective hunger in overweight and obese individuals. Our findings suggest that the effects of whey protein ingestion occur independent of a calorie-restricted diet and to a greater extent in individuals following a combined exercise program of resistance exercise, sprint intervals, stretching/yoga/pilates, and aerobic exercise training compared to standard resistance training.

The purpose of this study is to investigate if a brief, motivational interviewing intervention (NOURISH+MI) can improve retention and treatment adherence for parents enrolled in an intervention for their child's overweight (NOURISH+). The investigators hypothesize that children whose parents participate in NOURISH+MI will demonstrate lower attrition and greater adherence with NOURISH+, ultimately leading to greater treatment effects, compared with children whose parents are randomized to NOURISH+ or a control group.

APD356-A001-402 is a multicenter, double-blind, randomized, parallel-group pilot study of 12-week duration in overweight and obese adults. Approximately 225 subjects will be randomized to one of three treatment arms in a ratio 1:1:1 and will receive the combinations of lorcaserin 10 mg twice daily (BID) plus immediate-release phentermine-HCl 15 mg BID or 15 mg once daily (QD), or lorcaserin alone.

Increasing physical activity in older adults has important implications for treating obesity related metabolic conditions, however the interaction of aging- and obesity-related declines in physical function may make adding structured exercise particularly challenging for this group. Given these challenges, an alternative prescription to traditional structured exercise, may be short bouts of intermittent walking scattered throughout the day - this may be an effective strategy to increase physical activity, reduce sedentary behavior, and improve glycemic control in overweight/obese older adults. The purpose of this project is to determine how interrupting sedentary time with short bouts of moderate intensity walking affects important metabolic outcomes in older, overweight adults. It would also be of interest to compare the effects of short, frequent interruptions in sedentary behavior to a traditional exercise prescription (continuous 30 min walking bout) on metabolic outcomes (e.g., glycemic control, insulin sensitivity, and 24 h fat oxidation). Thus, the overall aims of the proposed research are to 1) Determine the effect of performing short bouts of moderate-intensity intermittent walking (IW) on glucose and insulin metabolism compared to uninterrupted sitting (US) in older overweight and obese adults. 2) To compare the effects of interrupting sedentary time (IW) vs. a traditional exercise prescription (continuous 30 m walk (CW)) on metabolism. The investigators hypothesize that interrupting sedentary time with intermittent walking will improve glucose and insulin metabolism compared to uninterrupted sitting and it will be as effective at improving metabolism as a single continuous 30 min walk.

This project will address the important area of childhood obesity and the risk of cardiovascular disease associated with obesity. This is a serious health concern since children who are overweight or obese are prone to other medical conditions including high blood pressure, abnormal lipid profiles,and type 2 diabetes. Although exercise and nutrition programs are recommended, evidence for the efficacy of these programs in improving cardiovascular health is lacking. Specific Aims: a) improve cardiovascular risk factors, b) increase physical fitness levels, c) improve lean body mass, d) enhance QOL of the child e) influence adherence rates to exercise and a healthy lifestyle change both during and beyond the conclusion of the program. Hypothesis 1a: Compared to baseline and matched controls, children randomized to a 10 week multidisciplinary fitness and nutrition program will show significant improved levels of cardiovascular risk factors. Specific Aim 2: To determine if a multidisciplinary fitness and nutrition program, when compared with a matched, WLC group will show a change in whole body assessment including a decrease in fat mass, an increase in percent lean body mass, and a decrease in percent body fat, as measured utilizing dual-energy X-ray absorptiometry Hypothesis 2a: Compared to baseline and matched controls, children randomized to a 10 week multidisciplinary fitness and nutrition program will show improved whole body assessments including. Specific Aim 3:To determine if a multidisciplinary fitness and nutrition program, when compared with a WLC group will show improved levels of fitness. Hypothesis 3a: Compared to baseline and matched controls, children randomized to a 10 week multidisciplinary fitness and nutrition program will show significant improvements in fitness including.

The investigators objective is to carry out a placebo-controlled, dose-response, randomized clinical trial to assess the effects of polyphenols or derived metabolites on cardiovascular disease risk in overweight adult subjects upon the consumption of pomegranate extract. The investigators hypothesis is that chronic consumption of a ellagitannin-rich source such as pomegranate extract could decrease serum oxidized-LDL as well as other inflammatory markers. The correlation between the effect exerted and the subjects' microbiota (capacity to produce the ellagitannin-derived metabolites urolithins) will indicate a possible role of urolithins on the effects.

The number of youth with Type 2 diabetes (T2D) is rising in the population, which is a concerning public health trend. There has been little research testing ways to prevent the development of this disease in children who are at increased risk to develop T2D. This study tests a family treatment program that treats 4-8 year old children who are at risk for T2D because they are overweight and have a family history of the disease. Sixty at risk children and their parents were assigned to one of 2 treatment conditions. Half of the families (randomly determined) received an intensive family treatment program that trains parents in how to increase healthier foods choices and physical activity for themselves and their children using "behavior modification" strategies. Children receiving this treatment were allowed to taste new fruits and vegetables used a pedometer to record how far they walked every day, and were given a "tool box" of toys and interactive games which promoted physical activity. The other half of the families only received instruction about healthier choices, but received no behavioral modification strategies or physical activity promotion tools. Improvements in children's body weight, blood measures, and behavior patterns were measured after treatment ended (6 months) and then again after 12 months. The results may lead to a better understanding of how family members can positively influence young children's behaviors to help prevent T2D. The objective of proposed study was to test a family-based intervention designed to reduce excess body weight, improve metabolic and cardiovascular profile, and improve diet and physical activity levels in 4 - 8 year old youth who are "at risk" for T2D. This intervention was tested in a 2-arm randomized controlled clinical trial. Primary Hypotheses: Compared to children receiving NPA, children receiving LMDP will show greater reductions in excess body weight, greater improvements in metabolic and cardiovascular measures, improved diet, increased physical activity, and reduced television viewing. Greater reductions in child excess body weight will be associated with greater improvements in metabolic and cardiovascular measures. Secondary Hypotheses: Compared to parents receiving the NPA intervention, parents receiving the LMDP intervention will show greater reductions in BMI. Greater improvements in parent BMI will be associated with greater improvements in child body composition, metabolic and cardiovascular measures, and behavioral outcomes. Compared to families receiving the NPA intervention, families receiving the LMDP intervention will show an increase in the number of fruits and vegetables and lower energy density foods stored at home.

The purpose of this study is to evaluate the most effectiveness between a personalized nutritional program with a counseling monthly phone call Versus personalized nutritional program with self help Informative Booklet in a group of obesity or overweight patients without counseling phone call.

This is a randomized controlled trial with enhanced usual care treatment control. The aim is to determine the effects of journaling and use of resource website on weight loss. There will be two groups of 55 participants each. The intervention condition will be asked to record daily weight, physical activity steps taken and pre-portioned food items and to complete two daily journaling activities. Participants will also receive weekly tracing data, a weekly blog from the principal investigator and have access to a weight control website. The control group will not have access to the tracking, journaling or website for three months. Investigators hypothesize that a website paired with tracking and journaling will be more effective in helping participants lose weight.

Childhood overweight continues to increase at an alarming rate and the need exists to find effective, accessible intervention strategies to prevent and treat children who are at risk for being overweight or are already overweight. The primary care setting provides an attractive option for families wishing to receive treatment, yet little is known about the feasibility, acceptance or efficacy of this intervention setting. The purpose of this study was to test two different primary care treatments that were intended to increase fruit and vegetable intake, increase physical activity, and reduce sedentary activity in children ages 4-8, who are overweight or at risk for becoming overweight. Both treatments involved the child and a parent/caregiver and both were conducted over a four month period. The parent/child dyads were selected from the pool of families who receive their primary care within the Geisinger Medical Center geographic area and who have been identified by their pediatrician as being overweight or at risk for becoming overweight (BMI >85th percentile for age). One group received weekly mailings which focused on healthy eating, promotion of fruit and vegetable intake and physical activity, and methods to reduce TV viewing time. The second group received a group-based intervention at one of the Geisinger Pediatric Clinic sites using specific behavioral strategies for increasing fruit and vegetable intake, reducing TV viewing and encouraging physical activity. Changes in overweight percentage, child BMI, lipid profile, glucose/insulin levels, and anthropometric measurements were analyzed, as well as treatment satisfaction and acceptance. The investigators hypothesized that children who receive Family Behavior Modification (FBM) in the primary care setting will show greater reductions in Body Mass Index (BMI), BMI z-score, percent overweight and waist circumference, and that children receiving FBM will show greater improvements in dietary intake, increased physical activity, reduced sedentary activity, and improvements in cardiovascular outcomes.
