This study aims to adapt a mobile health device (Amulet) for use in older adults. It is the second in a series of four research studies whose overarching goal is to conduct a program of pilot research aimed at developing and evaluating a technology-assisted wellness intervention for older adults with obesity who may or may not live in a rural area.
The purpose of this study is to determine if, in presence of a reduced calorie diet, a breakfast containing high quality protein source (eggs) would be more effective in reducing hunger and increasing feeling of fullness compared to a breakfast containing a lower quality of protein, but equal energy density. A previous pilot study with the same endpoints yielded borderline significant results; this study has been powered based on that pilot to interrogate our hypotheses.
Research suggests there is a connection between mood and weight. People who feel stressed or depressed are more likely to be overweight than people who don't have these feelings. Some individuals turn to food to cope, which can lead to gaining too much weight over time. Adolescence is an important time to understand these connections. Patterns of handling stress learned during adolescence set the stage for stress management in adulthood. This study is a randomized controlled pilot study with 60 adolescents who are at-risk for future, chronic obesity. We will test if taking part in a 6-week group program to lower stress and improve mood will be helpful to teens at-risk.
Given the importance of healthy lifestyle practices to cardiovascular disease (CVD) prevention and the utility of church-based interventions in African-American adults, the investigators developed a theory-informed, strategically-planned, health and wellness intervention with Rochester, Minnesota (MN) and Twin Cities area (Minneapolis, St. Paul, MN) churches with predominately African-American congregations. The objective of the study was to partner with churches to implement a multi-component, health education program through the use of core educational sessions delivered through a digital-application accessible on demand via interactive access on computer tablets and the Internet. The overarching goal was to increase the awareness and critical importance of healthy lifestyles for CVD prevention and provide support for behavior change.
The investigators will study sedentary behavior (SED) across pregnancy in young women. We hypothesize that SED will increase across pregnancy and that higher SED will be related to worse cardiovascular health, specifically elevated blood pressure (BP) and excessive gestational weight gain (GWG). Pregnancy is a biologically relevant period during which CVD risk factors may develop or worsen, contributing to future CVD. Pregnant women also spend most of their day sedentary, which is defined as too much sitting as distinct from too little exercise. SED has emerged as a risk factor, independent from moderate-to-vigorous physical activity (e.g., exercise), for elevated BP, obesity, diabetes, CVD, and mortality in general populations, but there are no recommendations for SED during pregnancy and few studies evaluate SED across pregnancy. These few studies are limited by small sample size, lack of repeated measures across trimesters, suboptimal SED assessment methodology, and a failure to link with clinical outcomes (e.g., BP, GWG). The investigators will address these gaps in a prospective study that will measure SED in 130 pregnant women across three trimesters using state-of-the-art objective activity monitors capable of measuring min-by-min activity by both intensity and posture. We will also measure BP and GWG during each trimester and, further, will link to and abstract all prenatal clinic weights and BPs, glucose screening results, gestational diabetes, preeclampsia, and adverse birth outcomes. Lastly, with the long-term goal of identifying women at high risk of SED during pregnancy and designing effective interventions, the investigators will efficiently evaluate correlates and determinants of SED which have never been studied during pregnancy.
This study evaluates effect of the Maternal Obesity and/or the By-pass on the Growth and the Nutritional Balance of the Child.The data stemming from mothers presenting obesity or an overweight during their pregnancy and the data stemming from mothers having had a by-pass will be compared with the data stemming from mothers with a normal BMI (Body Mass Index), considered as a reference group. It's the same for the data stemming from newborn children. The newborn children stemming from groups of obese mothers or in overweight will be compared with the data stemming from mothers belonging to the reference group.
There is a growing health burden in Sweden and Europe arising from the interrelated sequelae of metabolic disorders comprising impaired glucose tolerance (IGT), obesity and T2DM. Obesity and inactivity are the main drivers of IGT and T2DM and are responsible for up to 8% of health costs and 13% of deaths in Europe, with the risk of co-morbidities rising in parallel with increasing body weight. IGT and T2DM are the paradigm of inactivity-related disorders: the majority of people who have IGT or T2DM are overweight and inactive, with up to 80% being obese. A recent meta-analysis of 42 studies concluded that sedentary time was independently associated with a greater risk of T2D, all-cause mortality, cardiovascular disease incidence and mortality, and cancer incidence and mortality (breast, colon, colorectal, endometrial and epithelial ovarian cancers) (Ann Intern Med. 2015;162:123-32). A recent systematic review of trials published up to April 2014 identified 16 separate studies and concluded that there is considerable evidence of the positive effects of breaking up prolonged sitting time with light-intensity ambulatory physical activity and standing on postprandial metabolic parameters, including glucose, insulin and triglyceride levels (Med Sci Sports Exerc. 2015:47:2053-61). However, to date, all of the published experimental trials describing the beneficial effects of breaking up sitting time on metabolic risk markers have been restricted to acute exposure periods (1-5 days). We will perform a RCT intervention study, which examines the efficacy (clinically relevant responses) and practical implementation of low-impact training in sedentary obese individuals during the day.
The objective of this study is to determine how the protein source and the physical form of food consumed at breakfast impact food intake. Research will be conducted by assessing feelings of hunger, food preference and blood glucose in healthy adults following the ingestion protein-based (animal versus plant) drinks similar calorie and protein content.
The present study aimed to determine the effects of negative-calorie diet supplemented with exercise, on weight loss and lipid profile, and to compare its efficiency with low-calorie diet with exercise among elderly adult men with abnormal weight gain.
Negative-calorie diet is among the popular dieting guides for weight loss; however, there is still little knowledge about this method. The present study aimed to determine the effects of negative-calorie diet on weight loss and lipid profile, and to compare its efficiency with low-calorie diet in men.
