Filter by:Recently, researchers have been interested in the use of game play, mechanics and psychology for health-related engagement and behavior change. While initial studies have shown some increases in health knowledge and/or behavior through gaming, there remains concern that the vehicle for change is associated with a perceived sedentary behavior (6). More recently, commercially available gaming devices are able to directly promote physical activity through a new set of "kinetic controllers" added to the gaming experience. UHG plans to evaluate the most recent of these kinetic controller technologies in the context of a second iteration of JOIN (described above) to be implemented among a pilot group of overweight and/or obese children whose BMI percentile is above the 85th. This study will evaluate the effect of a commercial controller-free Exercise Gaming and Entertainment Experience (EGEE) on physical activity levels in the context of a weight management program in approximately 70 children ages 6 to12. The study will compare the differences in physical activity levels over 16 weeks in two groups of children.
The primary aim of the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) is to determine the relationship between lifestyle characteristics and obesity in a large multi-national study of 10 year-old children, and to investigate the influence of behavioral settings and physical, social and policy environments on the observed relationships within each country.
Background: Many unhealthy dietary and physical activity habits that foster the development of obesity are established by the age of five. Presently, approximately 70 percent of children in the United States are currently enrolled in early childcare facilities, making this an ideal setting to implement and evaluate childhood obesity prevention efforts. We describe here the methods for conducting an obesity prevention intervention randomized trial in the child care setting. Methods/Design: A randomized, controlled obesity prevention trial in 28 low-income, ethnically diverse child care centers located throughout Miami-Dade County, FL is currently being conducted over two years (2010-present) to test the efficacy of an intervention that poises teachers and parents as lifestyle change agents. The Healthy Caregivers-Healthy Children (HC2) program includes a curriculum focusing specifically on healthy food choices, increased exercise, and role modeling. The program targets food policy changes throughout the school, and via the child, caregiver, and teacher. Major outcome measures include child body mass index percentile and z score, fruit and vegetable and other nutritious food intake, and amount of physical activity. Discussion: Although few attempts have been made to prevent obesity during the first years of life, this period may represent the best opportunity for obesity prevention. Findings from this investigation should inform both the fields of childhood obesity prevention and early childhood research about the effects of an obesity prevention program housed in the childcare setting. (H1) A child care center-based obesity prevention intervention program that includes a teacher and parent nutritional gatekeeper and role modeling program will be more effective in maintaining BMI in 3-5 year olds compared to a control group. (H2) Role modeling (teacher and parent) will be identified as a significant mediator in preventing obesity among intervention children versus controls. (H3) A child care center-based multi-level obesity prevention intervention program will improve child nutrition (increased consumption of fruits and vegetables, decreased consumption of sweetened beverages) and increase physical activity level compared to a control group.
The purpose of this study is to test the effects of a cooking oil blend of dietary fats rich in medium chain triglycerides on energy expenditure and food intake in overweight and obese children.
The purpose is to determine the effect of sugars in solution on food intake and subjective appetite in 9- to 14-year-old normal weight boys. The investigators hypothesize that food intake after all sugars-containing solutions will be decreased in comparison to the control solution, with similar reductions in FI between high-fructose corn syrup -55 (HFCS-55) and sucrose. Food intake will be measured 60 minutes after consumption of 50g of HFCS-55, sucrose or glucose, or a control treatment. Subjective appetite will be measured at 15, 30, 45, 60 and 90 minutes.
The prevalence of childhood obesity has been increasing over the past couple of decades. Similar to adults, overweight and obesity in young children and adolescents is associated with an increased number of cardiovascular risk factors including dyslipidemia, hypertension, insulin resistance and Type 2 diabetes. Epidemiological and clinical studies suggest that foods and ingredients rich in select flavonoids, such as cocoa, red grape products, tea, citrus fruits, and strawberries are protective against the development of cardiovascular disease. Strawberries are rich in flavonoids, particularly anthocyanins, flavanols, flavonols, ellagic acid and its glucose ester, ellagitanin. A number of in vitro studies have observed that these isolated compounds, as well as strawberry extracts have the potential to affect outcomes of cardiovascular health, including vascular reactivity, cellular signaling and oxidant defense6,7. We hypothesize that strawberry intake will lead to improvements in select measures of cardiovascular function in overweight and obese adolescent males.
In this 3-phase study, following an initial small-scale (phase 1) feasibility trial, the aim of phase 2 of the project is to investigate whether a community-based, 12-month intervention for overweight and obese preschool children 2-6 years of age and their families will be effective in reducing the participants' degree of overweight (BMI z-score) and in improving quality of life. In the final phase (phase 3), participating children will be randomized to either receiving a multidisciplinary lifestyle intervention during the first 6 months (treatment arm), or 6 months later (control or wait list arm), in order to generate more robust effectiveness data. Participants will receive an additional free 6-month YMCA membership while participating in the study.
The investigators propose a randomized trial comparing higher levels of dairy intake compared to lower levels of dairy intake. Participants will be 20 boys and girls, age 10-13, overweight (>85%) who are currently consuming 1 or fewer servings of dairy per day. Each participant will be randomized to either higher or lower levels of dairy intake. A baseline calorimeter stay will determine 24-hour energy needs. Participants will then receive the diet they have been randomized to receive for 6 days and will then have a second calorimeter stay. During this 2nd stay, each participant will continue to receive the diet they were randomized to receive and will achieve a 300 kcal energy deficit through physical activity. The investigators hypothesize that children who receive a 300 kcal energy deficit from the energy expenditure of exercise and receive 3 to 4 servings of dairy products will show greater increases in fat oxidation compared to children who receive a 300 kcal energy expenditure of exercise and receive 1 or fewer servings of dairy products.
The purpose of this study is to evaluate the effectiveness of the Healthy Lifestyles Passport Program (HLPP) in preventing infant and childhood obesity. It is hypothesized that the participants in the intervention arm will exhibit less excessive weight-for-length gain from 4- to 6-months of age. In 2-years and 5-years, it is predicted that the participants in the intervention arm will yield lower Body Mass Index (BMI) z-scores than the participants in the control arm, who receive usual care.
The goal of the Minnesota center is to integrate primary care, home, and community-based intervention strategies to promote sustained patterns of change in food intake, physical activity, and body weight among low income, ethnically diverse children. A culturally matched family connector will create linkages among the settings to support parents in making home environment and parenting behavior changes conducive to healthy growth and development in their children. Specific Aim 1 To evaluate the effects of a three-year multi-setting parent-targeted randomized controlled intervention on the primary outcome, child BMI, compared to a standard primary care-only intervention among 500 low income ethnic minority two to four year old children who are at or above the 50th percentile of BMI for age and gender. Hypothesis 1: Children in the multi-setting parent-targeted intervention will have a lower BMI at 24 and 36 months, compared with children in the standard primary care only control group. Specific Aim 2 To evaluate the effects of a three-year multi-setting parent-targeted intervention on secondary outcomes, including change in child energy intake and physical activity energy expenditure, compared to a standard primary care-only intervention. Hypothesis 2: Children in the multi-setting parent-targeted intervention will have lower energy intake and higher energy expenditure over the three-year period, compared with children in the standard primary care-only control group. Specific Aim 3 To evaluate the effects of the multi-setting parent-targeted intervention on hypothesized mediators of change in dietary intake, physical activity, and BMI. Hypothesis 3: It is hypothesized that changes in parenting behaviors and the home food and physical activity environment will mediate changes in child energy intake and expenditure, and body mass index (BMI).
