Filter by:The investigators long-term goal is to increase the number of Summer Day Camps (SDC) that meet the National Afterschool Association Healthy Eating and Physical Activity (HEPA) Standards. The objective is to evaluate the effectiveness of a multi-component intervention designed to increase children's PA levels and improve the quality of lunches and snacks children consume in SDCs. The HEPA intervention is designed to target children, parents, staff, program leaders, and the SDC environment and uses a train-the-trainer model with SDC leaders to train their staff to deliver and integrate the intervention into routine practice. In the proposed study, the investigators will evaluate these HEPA strategies, using a 4-year randomized controlled trial with 20 SDCs. An important feature of the study will be the evaluation of maintenance of the intervention after the removal of research support (e.g., training, boosters) during the final year, as well as costs associated with implementation. The investigators hypothesize that intervention SDCs will achieve significantly greater increases in HEPA, compared to control SDCs. The investigators expect the study to support the cost-effectiveness and maintenance of our strategies for promoting HEPA that will facilitate SDCs meeting newly-established HEPA standards for this setting.
The investigators long-term goal is to advance the adoption and successful implementation of policies that promote PA and nutrition in after school programs (ASP) nationwide. The investigators objective here is two fold. First, the investigators will test the effectiveness of two promising strategies designed to 1) increase the amount of PA children accumulate while attending an ASP and 2) promote changes in the nutritional quality of the snacks served. This represents a fundamental step in establishing practice-based guidelines (best practices) for the uptake and achievement of public health policy goals (CA and Harvard). Second, the investigators will examine the barriers and facilitators to implementing these strategies. The expected outcome of this study is evidence supporting best practices for ASPs to employ to meet policy goals.
The investigators hypothesized that the addition of 6 minutes of exercise during the school day would increase physical fitness in elementary school students as demonstrated by longer distances run in 2 minutes and a decrease in heart rate at the end of the exercise.
This is a randomized controlled pilot trial of a peer-based, social media intervention to prevent obesity in infants.
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 overall objective is to explore the mechanisms by which macronutrients regulate food intake and weight gain in Prader Willi Syndrome (PWS). Previous studies from the investigators' labs suggest that the increased appetite of PWS may be triggered or maintained by an increase in the levels of ghrelin, an appetite-stimulating hormone produced primarily by the stomach. This study will compare the effects of low carbohydrate diet versus low fat diet on levels of ghrelin, appetite suppressing hormones and markers of insulin sensitivity in patients with PWS. The investigators hypothesize that the low carbohydrate diet will suppress plasma active ghrelin and increase appetite-suppressing hormones to a greater degree and for longer duration than the low fat diet and will thereby reduce hyperphagia and increase satiety. The investigators also hypothesize that the low carb diet will improve hormonal and metabolic markers (fatty acids, amino acids and organic acids) of insulin sensitivity and inflammatory cytokine profiles of children with PWS.
This is a single-group feasibility pilot trial of a peer-based, social media intervention to prevent obesity in infants.
The Colorado Longitudinal Eating And Physical activity (LEAP) Study utilizes a social ecological approach to explore individual, family and environmental factors and their relationship to child weight status over a 3 year timeframe. Our primary research questions are as follows: 1. Are behavior changes (increased willingness to try new foods and gross motor skills) from a preschool nutrition and activity program, The Food Friends®, sustained through early elementary school? 2. Do The Food Friends® programs have an impact on reducing the percentage of children considered overweight and/or obese over a 3 year timeframe? 3. Do food preference and gross motor performance directly affect child weight status or are they mediators to dietary intake and physical activity?
The purpose of this study is to develop and evaluate the effects of a school breakfast policy initiative (SBPI) on the incidence of overweight and obesity as well as breakfast patterns (both inside and outside of school) among 4th-6th grade children. The study integrates research, education and extension to promote healthy breakfast consumption among low-income children in urban schools and will leverage ongoing SNAP-Ed and the School Breakfast Program efforts.
Children born to obese women are at risk of increased adiposity and later adverse metabolic outcomes. We have conducted a follow-up study on an existing clinical trial, called the LiP study (Lifestyle in Pregnancy), registration number NCT00530439,in which 360 obese pregnant women were randomized to either lifestyle intervention or routine obstetric care. This present study follows the children until 3 years of age. We have the hypothesis, that the intervention during pregnancy results in a lower degree of adiposity and metabolic risk factors in the offspring. Clinical examination is taking place at age 2.5-3 years including anthropometric measurements, Dual energy x-ray (DXA) scans and blood samples measuring metabolic markers.In addition, we have included an extra control group of children born to normal weight women, who were not part of a lifestyle intervention program during pregnancy. We have the hypothesis that the children of the normal weight women have a better metabolic profile than the children born to the obese women.
