Filter by:The purpose of this study is to preliminarily validate a parent-focused obesity intervention program for parents of low-income, African American preschoolers who are currently overweight (> 85th BMI %tile). Half of the participants will receive an intervention that is eight sessions in length and carried out in the participant's home. The sessions will target the nutrition and physical activity knowledge of parents and their motivation for changing parenting related to family eating habits and activity level. The remaining participants will receive an attention comparison control condition (ACCC), which includes one home visit, 7 newsletters and 4 monthly support phone calls. It is hypothesized that children of parents receiving the intervention will have decreases in BMI %tile, consume more fruits/vegetables and fewer sugary beverages, and engage in more activity as compared to ACCC.
The investigators aimed to study the effect of supplementation with species of Lactobacillus on anthropometric measurements, body composition, appetite and serum lipid profile in overweight and obese adults
The polyglucosamine, specification L112 is a medical device and in this clinical trial used for weight reduction of overweight and obese participants. The rationale for this study is to show that overweight can be reduced by taking 2 times daily 2 tablets with the main meals with the highest fat content.
To study the effects of Flaxseed supplement on weight, lipid profile and inflammatory factors in subjects with over weight and obesity, 50 patients will be randomly allocated to receive placebo or 30 grams milled Flaxseed for 12 weeks; both groups will be advised to adherence the investigators' diet and exercise program too. At the first and the end of the intervention, weight, waist and hip circumference, lipid profile and some inflammatory markers will be assessed and compared between groups.
Nonalcoholic fatty liver disease is a serious health condition in overweight children which can lead to heart disease. This project will examine the links between liver health and cardiovascular risk factors in overweight and obese children, and will test the effect of a long-term after-school exercise program. Provision of comprehensive evidence for the benefits of exercise on children's health may reduce barriers to vigorous physical activity programs during a childhood obesity epidemic.
Too much body-fat has been linked to a low-grade inflammation throughout the body. This inflammation is thought to then cause different diseases, like heart disease and diabetes. A lower amount of inflammation is usually seen in people that follow a high fiber diet. A reason for this is the microbes that live in our gut. Fiber is a main food source for these microbes. This allows fiber to actually change the type of microbes that live in our gut. Also, when fiber gets fermented by these microbes, health-promoting waste products get released. We aim to determine how exactly our gut microbes contribute to the health properties of fiber. We hypothesize that fiber's health properties depend on how the gut microbes respond to the fiber. To test this, we plan to add three different fibers to the diets of healthy overweight and obese individuals for six weeks. We then will determine how the different fibers affect an individuals' health by looking at how established markers of health change from adding the fiber. Following this, we will see how an individual's gut microbes respond to the added fiber. The response will be decided by looking at changes to the microbe community, as well as their ability to ferment the fibers. By connecting health outcomes to the gut microbes' response, we can test if the gut microbes' response to the fiber determines the fiber's ability to effect health. If we can understand how our gut microbes respond to different fibers and the importance of that response. Then we could personalize diets to have a greater impact on improving health.
Oxytocin is a peptide hormone produced in the brain that regulates food intake. However, the mechanisms for this effect in humans is not yet clear. In this study, the investigators will therefore examine the effect of a single dose of intranasal oxytocin (compared to placebo) on levels of appetite-regulating hormones and functional magnetic resonance imaging activation of areas of the brain involved in food motivation.
This research focuses on overweight, sedentary children whose health, cognition, and academic performance are therefore at risk, and who may be particularly responsive to exercise interventions. This study will determine whether regular exercise per se (i.e. compared to attention control, or placebo, condition) benefits children's cognition and achievement, and will provide insight into neural mechanisms. A substudy will examine exercise-induced changes in brain structure. Provision of comprehensive evidence for the benefits of exercise on children's health may reduce barriers to vigorous physical activity programs during a childhood obesity epidemic by persuading policymakers, schools and communities that time spent in physical activity enhances, rather than detracts from, learning.
This study aims to make a proper scientific assessment on the dietary intake and physical activity levels of a representative sample of the urban population of 8 Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Perú and Venezuela). The study was based on complex, multistage sample design, stratified by conglomerates, being all regions of each country represented, and random selection of main cities within each region according to probability proportional to size method. Sample will be stratified by gender, age (15 to 65 years old), and socioeconomic level. Socioeconomic levels will be balanced and divided in three strata (high, medium and low) based on national indexes used in each country. All the study sites are university-based and will adhere to a common study protocol for training, implementation of fieldwork, data collection and management, and quality control procedures to be performed simultaneously. All participants will be required to provide a written informed consent. A pilot study at small scale will be performed in each country in order to test procedures and tools involved in ELANS. Anthropometric variables, including body weight, height, waist, hip and neck circumferences will be measured according to a standardized protocol. Nutritional intake evaluation will be performed using two 24-hour dietary recalls, with 'multiple pass' procedure and a food frequency questionnaire. Nutritional data will be entered in Nutrition Data System for Research (NDS-R, Minnesota University) after a harmonization process between local foods and NDSR database. Physical activity and energy expenditure will be assessed by IPAQ-long version questionnaire and 7-day accelerometry.
The purpose of this study is to determine the feasibility and acceptability and efficacy of a two month technology-based weight loss program for overweight and obese college students.
