Active clinical trials for "Overweight"

In the present study it is hypothesized that a reduction of the inflammatory status may prevent the occurrence of disorders and diseases related to overweight. In this study the effects of nutritional compounds will be studied in overweight men with a low grade inflammatory status. We will investigate the effects of 3 different food treatments as compared to a placebo on markers of inflammation and on parameters of glucose and fat metabolism. The three different food treatments are a food mix and two yogurts each containing different probiotic strains. The food mix is composed of a mix of nutritional components, each reported to affect inflammation parameters and (or) anti-oxidant status but different in their -hypothesized-mode of action.

This randomized control study (sponsored by the NIH, NIDDK) is aimed at reducing BMI in overweight adolescents at risk for the development of type 2 diabetes. The study will examine whether an integrated primary care, web and cell-phone-based intervention can produce initial and sustained improvements in anthropometric, behavioral, metabolic, and physiological outcomes in overweight adolescents. The primary goal is to reduce BMI (Body Mass Index)in overweight adolescents.

Physical activity is thought to be a key element in preventing the obesity epidemic and the associated cardiovascular and metabolic diseases. However population-based studies directed at promoting physical activity in youth have shown limited success in obesity prevention. The aim of this study is to assess whether an intervention integrating socioecological changes, which has the potential to induce sustained changes in physical activity, prevents overweight and cardiovascular risk in adolescents.

A randomized study is proposed to determine effects of 8 weeks of an interactive multimedia educational program compared to waiting list control group on improving health and weight status in Chinese-American children, ages 8 and 10, over a 6 months period. A total of 60 Chinese-American children and their families will be randomized to either the intervention group or waiting list control group. The intervention is based on Social Cognitive Theory and principles of Chinese culture and practices. The intervention program includes a one-hour small-group session for eight weeks for children and two 2-hour small-group sessions for parents. Baseline data will be collected before assigning the children to the intervention or control group. Follow-up data will be collected immediately after the intervention and 3 months and 6-months post intervention. A repeated measures (longitudinal) design employing a linear mixed models approach will be used for analysis.

Pregnant and lactating women receive n-3 fatty acids starting from week 15 of gestation until 4 months post-partum (pp) in comparison to a control group, who only gets information about adequately healthy nutrition during pregnancy and lactation. The amount of fat in newborns is measured through skinfold thickness, ultrasound, and magnetic resonance imaging (MRI). It is hypothesised that a reduction in arachidonic acid intake and an increase of n-3 LC PUFAs (long chain polyunsaturated fatty acids) via supplements containing docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) could lead to less expansive fat tissue development in the first year of life.

The Diabetes Prevention Program (DPP) demonstrated that an intensive lifestyle intervention resulting in modest weight loss and increased physical activity can delay or prevent the development of type 2 diabetes in those at increased risk for the disease. The lifestyle program used, however, was not designed for delivery on a public health scale. Successful community translation of the DPP's findings will require close collaboration with an established community organization committed to improving community health and experienced in implementing sustainable health and wellness programs. With exceptional reach into diverse U.S. communities, the Young Mens Christian Association (YMCA) may be an ideal community partner. We have been collaborating with the YMCA organization for over a year to design a robust recruitment and implementation model that is sensitive to the unique needs and resources of a community organization. We now propose to evaluate if a group-based adaptation of the DPP lifestyle intervention can be successfully implemented by YMCA staff, in YMCA facilities. We have designed this study to develop preliminary data about the reach, effectiveness, and consistent implementation of the DPP lifestyle intervention in this context. This pilot study has two primary aims: 1) to demonstrate the extent to which YMCA staff trained by DPP study personnel can administer a group-based adaptation of the DPP lifestyle intervention in a fashion consistent with DPP intervention protocols, and 2) to evaluate if the intervention program delivered by the YMCA results in changes in body mass, physical activity, and dietary intake that are consistent with a level found to be associated with diabetes risk reduction during the DPP trial. We will also collect valuable data about the feasibility and reach of a selective, community-based marketing and screening approach for recruiting program participants. In combination, these data will enable us to design and conduct a larger, future 3-year trial focusing on the effectiveness and sustainability of community DPP translation in multiple YMCA settings.

The Diabetes Prevention Program (DPP) demonstrated that an intensive lifestyle intervention resulting in modest weight loss and increased physical activity can delay or prevent the development of type 2 diabetes in those at increase risk for the disease. The lifestyle program used, however, was not designed for delivery on a public health scale. Successful DPP translation will require a sustainable partnership between a health care system and an established community organization committed to community health and experienced in implementing sustainable health and wellness programs. We have been collaborating with local health system and community administrators for over a year to design a 'real-world' clinic-based screening model to identify and refer high-risk patients for a group-based adaptation of the DPP lifestyle intervention in community facilities. We have designed this study to develop preliminary data about the feasibility and yield of clinic-based screening and referral, as well as the effectiveness of the adapted lifestyle intervention. This pilot study seeks to: 1) evaluate the feasibility of a strategy to implement American Diabetes Association (ADA) recommendations for clinic-based diabetes-risk testing and to refer high-risk patients for a community-based lifestyle intervention; 2) compare two strategies to enhance community-based program participation by referred patients; 3) demonstrate the capability of community facilities to schedule and enroll referred clinic patients at high-risk for diabetes and to deliver a modified, group-based DPP lifestyle intervention consistently; and 4) compare levels of weight loss and physical activity achieved by referred clinic patients with pre-diabetes who participate in a free-of-charge, group-based DPP lifestyle intervention at community facilities compared to a free-of-charge, traditional, one-on-one DPP lifestyle intervention at a DPP research site. Addressing these issues now will enable us to evaluate this partnered DPP translation model with a larger, more robust future study that will involve referral by multiple primary care clinics, program delivery at more community sites, and a 3-year follow-up period.

The purpose of the present study is to determine whether weight gain may be prevented by a small group seminar-based two-year educational intervention on healthy lifestyle in freshmen at the Faculté de médecine de l'Université de Sherbrooke.

The purpose of this study is to test the effectiveness of a weight loss and weight loss maintenance intervention among low income women, conducted in a community health center setting.

Epidemiological studies have indicated that the consumption of citrus fruit is inversely associated with the risk of cardiovascular disease. However, clinical data regarding the effects of blood orange juice upon endothelial function is scarce. This randomised, crossover study investigates whether blood orange juice compared to a control drink improves blood vessel function and other cardiovascular health indicators (such as blood pressure and blood lipids). All the subjects will be asked to consume blood orange juice and a control drink in a randomised order, each over a 2-week period, divided by a 1-week wash out period.
