BACKGROUND There is an increasing interest among nutritional researchers to perform lifestyle and nutritional intervention studies in a home setting instead of testing subjects in a clinical unit. The term used in other disciplines is 'ecological validity' stressing a realistic situation. This becomes more and more feasible because devices and self-tests that enable such studies are more common...

Introduction: Reducing the labour by an unskilful person is an important strategy in promotion of mother's health and reducing the maternal mortality as the fifth millennium development goals. Methods: This retrospective and descriptive study was accomplishd in 2010.The samples were 189 Iranian mothers with labour by unskilful person in urban and rural area affiliated to Mashhad University of M...

Food away from home, especially fast food, is often cited as contributing to rising obesity. This negative publicity can affect the demand for restaurant meals. In this study econometric models explaining visits to table service and fast food restaurants are estimated. The explanatory variables include not only standard demographic and economic measures but also measures of nutrition knowledge,...

We present a fully automated system for real-time markerless 3D human motion capture. Our approach, based on fast algorithms, uses simple techniques and requires low-cost devices. Using input from multiple calibrated webcams, an extended Shape-From-Silhouette algorithm reconstructs the person in real-time. Fast 3D shape and 3D skin parts analysis provide a robust and real-time system for human ...

We present an automated system for real-time marker-free motion capture from two calibrated webcams. For fast 3D shape and skin reconstructions, we extend Shape-From-Silhouette algorithms. The motion capture system is based on simple and fast heuristics to increase the efficiency. Multi-modal scheme using both shape and skin-parts analysis, temporal coherence, and human anthropometric constrain...

Background: Obesity rates are higher among rural versus urban adolescents. To examine possible mechanisms for the rural-urban adolescent obesity disparity, we examined the direct and indirect effects of food purchasing patterns, and the home, school, and consumer food environments on dietary intake among rural adolescents. Methods: A baseline survey was conducted among adolescents in eight rura...

High population rates of obesity and nutrition-related chronic diseases warrant an examination of the role of food and nutrition education in health promotion. Using a mixedmethods approach, this study explored student enrolment trends in, and perceptions of, Home Economics Food and Nutrition education in a Canadian province. Enrolment in Home Economics Food and Nutrition courses for grades 7–1...

In cooperation with a group of general practitioners (GP), we investigated the possible risk and benefit of prehospital initiation of thrombolytic therapy in acute myocardial infarction (AMI) with anisoylated plasminogen streptokinase activator complex (APSAC) at the patient's home. During a 14-month period, 58 patients with suspected AMI were evaluated by their GP using a protocol with strict ...

We design and build a system called EpiFi, which allows epidemiologists to easily design and deploy experiments in homes. The focus of EpiFi is reducing the barrier to entry for deploying and using an in-home sensor network. We present a novel architecture for in-home sensor networks con gured using a single con guration le and provide: a fast and reliable method for device discovery when insta...
