Filter by:Canadian statistics indicate that the incidence of obesity is increasing and that the occurrence of diabetes in obese individuals is 5-fold greater than those with a healthy weight, making weight control in this population particularly relevant. Preliminary clinical data has shown that the whole grain, Salba, may improve type 2 diabetes control, reduce after-meal blood glucose, cardiovascular disease (CVD) risk factors and suppress appetite. Its use may therefore have potential implications in long-term weight management, while improving diabetes. The objective of this research (weight loss) is to evaluate whether adding Salba to an energy reduced diet for six months will result in greater weight loss compared to control in overweight and obese individuals with type 2 diabetes. The study recruited 77 overweight or obese individuals with type 2 diabetes. They were instructed to follow a calorie restricted diet and their regular diabetes therapy together with regular exercise. Participants were randomly assigned to receive 30 g Salba/1000 kcal of daily energy requirements, or an oat bran control supplement matched for energy. The effect of the supplements on weight-loss (including waist circumference, % body fat) and glucose control (A1c, fasting glucose levels) will be assessed. In addition, related outcomes such as low-grade body inflammation, hunger-regulating hormones (ghrelin, adiponectin), safety measures (urea, creatinine, ALT and prothrombin time) and satiety scores were evaluated. Modest weight loss has been associated with improved glucose control in individuals with type 2 diabetes. Addition of Salba to an energy reduced diet may facilitate greater weight loss and improve glycemic control and CVD risk factors compared to such a diet alone. Salba may also promote maintenance of weight loss and therefore help prevent weight gain by providing feelings of fullness that reduce appetite. In light of the high incidence of obesity in individuals with diabetes, Salba grain may be a useful addition to the diet.
Obesity can cause many health problems, including high blood pressure, diabetes, heart disease, and stroke. Although some people may lose weight through diet and exercise, many regain weight over time. There is a need to study new ways of helping people maintain their weight. The purpose of this research is to study the effect of a weight maintenance program provided through home television sets connected to the Internet.
Barley, like oats, is a rich source of the soluble fibre β-glucan, which has been shown to significantly lower LDL-cholesterol (LDL-C). However, barley foods have been less widely studied.
Generally, people with low levels of high-density lipoprotein (HDL) in blood are more likely to get heart disease than those who have normal or high levels. Dietary fat, whether the harmful type (saturated) or beneficial type (unsaturated) raises HDL levels. Dietary carbohydrate lowers HDL. The investigators are doing this research study to find out why the amount of HDL in a person's blood is affected by dietary unsaturated fat and carbohydrate. The investigators will trace the ability of the HDL in a person's blood to take up cholesterol, get bigger, and then leave the blood by passing into the liver. The investigators want to know if dietary unsaturated fat improves the ability of HDL to do this compared to dietary carbohydrate.
To assess the feasibility and acceptability of genuine pharmacy follow up of people wishing to lose weight.
The objective of this study is to determine the independent and combined effects of weight status and the level of dietary restraint on the relationship between package unit size and food intake.
Young children who are overweight or at risk for overweight are at increased risk for becoming obese as young adults and developing type 2 diabetes and cardiovascular disease. To date, there have been no interdisciplinary interventions that targeted predominantly ethnic minority low-income children and parents and taught them to work together to improve nutrition and exercise. Using a two-group, repeated measures experimental design, this proposed study will test a 12-week intensive intervention on nutrition, exercise and coping skills (Phase I) and 9 months of continued monthly contact (Phase II) to help overweight 2nd, 3rd, and 4th grade children and their parents improve self-efficacy, health behaviors, weight status, and adiposity. The study will take this intervention to the community in which children and parents live, working with four schools in Alamance-Burlington County, NC, and four schools in Wilson County in the early evening. A total of 356 Black, Hispanic, and White children with a BMI >85th percentile and 356 parents with a BMI >25 kg/m2 will be inducted over 3 ½ years and randomized by school to either the experimental or control group. Data will be collected at Time 1 (Baseline), Time 2 (Post Phase I-Intensive Intervention), Time 3 (Post Phase II-Continued Contact), and Time 4 (6-Month Follow-Up). Data collected will include scores on the Health Promoting Lifestyle Profile II in the parents; eating self-efficacy in the children (CATCH) and parents (Eating Self-Efficacy Scale) and exercise self-efficacy in the children (CATCH) and parents (Exercise Self-Efficacy); health behaviors in the children and parents (3 Day 24-Hour Food Recall and 4 Day Accelerometry Measurement); weight status in the children (BMI percentile) and parents (BMI); and adiposity in the children and parents (waist circumference and triceps and subscapular skinfolds). Data analysis will use general linear mixed models to test the hypotheses. Decreasing overweight in children and parents is urgently needed, and helping children and parents to work together to improve their nutrition and exercise patterns by making small lifestyle pattern changes may decrease future health care costs and decrease morbidity and mortality. The knowledge to be gained from this study may provide a foundation for extending this intervention to other Black, Hispanic, and White children and parents in other communities to assist them to manage their weight.
Obesity is a major public health problem among older adults, with 31% of non-institutionalized older persons (60 years+) in the US obese and projections indicating that this will rise to 40% by 2010. A second public health challenge on the horizon for the aging US population is the increasing number of individuals experiencing cognitive decline, dementia or Alzheimer 's disease. Recent clinical trials have demonstrated efficacy in reducing risks associated with both of these significant and increasingly pervasive health problems, which are more common among rural, low income and ethnic minority populations. The Diabetes Prevention Program (DPP) Lifestyle Intervention produced sustained weight losses in a large, diverse population of high-risk individuals and dramatically reduced rates of type 2 diabetes onset, particularly among older adults. SeniorWISE produced improvements in memory in community dwelling older persons. Transferring these exciting technologies to community settings where they can benefit older adults is a pressing public health need. Therefore, the current project seeks to transfer these two evidence-based interventions to older adults in a rural state using senior centers as the venue for dissemination and lay health educators to deliver the interventions. Senior centers are a particularly attractive context for translation of evidence-based health promotion technologies in predominantly rural states like Arkansas because they have a well-established infrastructure in communities and share a common goal of promoting healthy aging and reducing health care costs. The 3-year randomized, controlled trial will evaluate translation of the interventions by randomizing senior centers (N=16) across Arkansas to implement either (1) the DPP Lifestyle Weight Loss Program or (2) the SeniorWISE Cognitive Training Program. Older (age > 60) adults (N=288) nested within senior centers will receive the programs delivered in a group format by a trained lay health educator. Primary outcomes are changes in body weight and cognitive functioning at 12 months. The multi-level evaluation plan will characterize reach, effectiveness, adoption, implementation and maintenance of the interventions, with a cost effectiveness component.
The study purpose is to evaluate the effectiveness of a culturally appropriate, faith-placed lay health advisor intervention aimed at increasing fruit and vegetable intake and physical activity among intergenerational Appalachian individuals and families.
The purpose of this research project is to assess the efficacy of a weight loss intervention for chronic disease prevention that focuses on daily self-weighing as the primary self-monitoring strategy compared to a delayed-intervention control group. While daily self-weighing has been shown to be effective for weight loss in observational research, there is limited experimental evidence testing this association and most is derived from intensive interventions that may overshadow the effects of self-weighing. To mitigate this, the investigators will examine whether daily self-weighing is effective for weight loss under self-directed conditions using a randomized-controlled design. The investigators will conduct a 6-month randomized trial in 88 overweight and obese adults to compare a daily self-weighing intervention to a delayed-intervention control group. Changes in weight, diet and physical activity, and psychosocial measures will be examined. Main Study Hypothesis: Participants in the group randomized to receive the daily self-weighing intervention will have greater percent weight loss at 6 months compared to those in the delayed control group. Secondary Hypothesis: Participants in the group receiving the daily self-weighing intervention will report greater engagement in diet and physical activity behaviors that produce caloric deficits, greater self-efficacy and motivation, and no differences in body satisfaction, disordered eating, or depressive symptoms compared to those in the control group.
