Filter by:The primary aim of this feasibility study is to determine if a theory-based lifestyle intervention consisting of telephone counseling is associated with improvements in physical activity and dietary intake.
The aim of this study was to assess the relevance of NRI or athletes' NRI (ANRI) utilization to detect nutrition-related risks of failure in competition in the particular population of rowers. In the morning, 60 to 90 minutes before the first race of a national level multi-races competition (three races for each subjects), body weight were measured and blood samples were collected with subjects at rest and in post-absorptive condition (last meal at least 2.5 hours before blood collection). Body weight was also recorded in the same conditions six weeks before the competition to calculate weight state (actual weight /usual weight ´ 100) and subjects were asked to identify the date of diet beginning. Body weight was measured using a floor scale (Mettler-Toledo floor scale, France), body mass index (BMI) was calculated from the ratio of weight (in kg) by height squared (in meters) and training volume (total duration of training in a week) was determined after discussion with athletes and coaches.
Poorly controlled hypertension (HTN) remains one of the most significant public health problems in the United States, in terms of morbidity, mortality, and economic burden. Despite compelling evidence supporting the beneficial effects of therapeutic lifestyle changes (TLC) on blood pressure (BP) reduction, their effectiveness remains untested in primary care practices, especially among minority patients who share a greater burden of HTN-related outcomes including chronic kidney disease, stroke and heart failure. This randomized controlled trial offers a unique opportunity to address this gap in the literature. Among 200 hypertensive African-Americans who receive care in community- based primary care practices, we will test the effectiveness of a culturally-tailored comprehensive therapeutic lifestyle intervention, delivered through group-based counseling and motivational interviewing (MINT-TLC) vs. Usual Care (UC). MINT-TLC is designed to help patients make appropriate TLC and develop skills to maintain these changes long-term. Patients in the MINT-TLC group will attend weekly group classes focused on TLC for 12 weeks (intensive phase); followed by individual motivational interviewing (MINT) sessions for 3 months (maintenance phase). Trained research personnel will deliver MINT-TLC with appropriate treatment fidelity procedures. Patients in the UC condition will receive a single individual counseling session on TLC and print versions of the intervention materials. The primary outcome is within-patient change in both systolic and diastolic blood pressure from baseline to 6 months. Secondary outcomes are levels of targeted therapeutic lifestyle behaviors; and proportion of patients with adequate blood pressure control at 6 months
This study will test a website for teens designed to help them improve both diet and physical activity. The website will have several components: educational messages, role model stories, goal setting, self-monitoring forms, problem solving, a monitored discussion forum, and diet and physical activity (PA) assessment questionnaires.
Building on existing intervention strategies of the Tu Salud Si Cuenta media campaign, this proposed worksite pilot study will be testing a new feature by designing worksite promotion intervention strategies. The purpose of this study is to test the feasibility of a worksite-based physical activity and healthful food choice. The intervention will be among two worksites in the Lower Rio Grande Valley who employ primarily Mexican-American personnel.
Over the past 30 years obesity has reached epidemic proportions in the United States (Ogden et al, 2006). While this epidemic affects all socioeconomic levels, certain racial/ethnic groups such as Hispanics, are disproportionately affected by obesity and diabetes. The age of onset of excess obesity in Hispanic females, formerly young adulthood, is now younger. Childhood obesity poses intermediate and long-term health risks, including: type 2 diabetes, hyperlipidemia, elevated blood pressure, and metabolic syndrome. Although biological factors may influence a child's risk for becoming overweight, the home environment has been shown to be a predisposing and reinforcing contextual factor for unhealthy eating and exercise behaviors. Since parents are the primary transmitters of Hispanic cultural practices and significantly influence their children's diet and physical activity behaviors from preschool through high school, family-based weight-gain prevention interventions are likely to be effective. The goal of this implementation study is to contribute to the reduction of racial/ethnic disparities in obesity and risk of type 2 diabetes by tailoring a recently successful childhood obesity prevention program originally developed for African American girls to implement and evaluate with preadolescent Hispanic girls.
Compared to solid foods, the nutritional energy of drinks may bypass the appetite regulation leading to obesity development. Although drinks sweetened with aspartame are available the anticipated positive effect of these drinks on obesity development has not been convincing. However, the mechanisms linking drinks intake to obesity are yet to be clarified. The investigators aim is to investigate the short-term effects of soft drinks (sugar-sweetened and artificially sweetened (aspartame)), milk and water on the concentration of circulating appetite-regulating hormones, the subjective sensations of hunger and satiety (measured by visual analogue scales) and energy intake. The study is a crossover, intervention trial with 24 overweight, healthy volunteers. The subjects will be tested on four separate days for four hours. Each test day a preload drink (sugar-sweetened soft drink, aspartame-sweetened soft drink, semi-skimmed milk or water) is served. The investigators expect to clarify the mechanisms linking drinking habits to obesity development and provide scientifically based nutritional guidelines.
The association between psoriasis and obesity has been questioned by physicians for many years. Studies have shown that the risk of having psoriasis is increased in people with a high body mass index, which is a measurement of obesity. There have been case reports of remission of psoriasis after gastric bypass surgery. Furthermore, other studies have shown that certain inflammatory diseases (such as rheumatoid arthritis) can be improved by dietary changes. The purpose of this study is to assess whether a low carbohydrate or low fat diet can be helpful in the treatment of psoriasis.
This research project brings together the American Academy of Family Physicians (AAFP) National Research Network (AAFP-NRN) and the AAFP's public health initiative, Americans In Motion (AIM). This project will develop and evaluate a practice improvement program to improve family physicians' delivery of effective patient-centered behavior change interventions for "fitness" (physical activity, nutrition and emotional well-being). The investigators seek to develop a unique program that positions fitness in a central role as "the treatment of choice" when dealing with issues of prevention and treatment of chronic conditions. In addition, this newly developed program is intended to help shift the paradigm of family physicians' use of common advice-giving methods to more effective patient-centered lifestyle counseling. Ultimately, this program will seek to improve care for all patients through fitness-related physician interventions. Outcomes: This study design will allow the investigators to evaluate whether (and how) dissemination of educational materials impacts patient intervention by first engaging clinicians and staff in their personal use of these materials. This project will also evaluate the effects of the behavioral change tools, as well as, the added impact of new physiologic feedback measures (HOMA-IR and NMR Lipoprotein profiles) on physical activity and diet in study participants. Conclusion: Primary care offices can become more effective settings to help patients improve physical activity, diet and emotional well-being. Demonstrating the value and impact of creating "healthy offices" that endorse and support clinicians, office staff and patients in the use of effective educational materials fits well with the new model of care as part of the AAFP's "Future of Family Medicine" initiatives, which emphasize the importance of lifestyle decisions and supporting successful changes in behaviors within primary care. This project will help define how to accomplish this.
If eating a "Paleolithic" diet helps improve these diseases, this would be the first step in both improving people's health as they get older as well as contributing to future national dietary guidelines for Americans.
