Filter by:Live Well, Viva Bien (LWVB) is an NCI-funded, cluster randomized controlled trial (RCT) that was conducted in 15 subsidized housing complexes to evaluate the efficacy of a multicomponent intervention comprised of a year-round, discount, mobile fresh F&V market -'Fresh To You' (FTY)- that was paired with a nutrition education component including included educational newsletters, campaigns, taste-testings and videos in both English and Spanish. The primary aim of the LWVB grant was to study the efficacy of FTY combined with a motivational/educational intervention to see if it increased F&V consumption compared to a Comparison intervention (attention placebo).
The overall purpose of the study is to evaluate nutrition education interventions to promote pulse incorporated complementary food to the wider rural community through the government system to improve maternal knowledge, attitude and practice (KAP) and nutritional status of young children (6 to 24 months). The hypothesis is that nutrition education improves mothers knowledge, attitude and practice of pulse incorporated complementary food and improves dietary intake of iron and zinc and nutritional status of young children.
Although increasing age is associated with declining health and function, there are wide variations between individuals in the ageing process. Some of these differences are explained by differences in lifestyle, but little is known about the determinants of lifestyle in older age. The proposed project will describe influences on health behaviour and lifestyle in older adults. Investigators will undertake a prospective study of community-dwelling older people who use any of the Medicine for Older People Services in Southampton, allowing us to gain obtain important insights into the relationship between health behaviour, lifestyle and health outcomes in older people. Our principal aim is to identify key points on the ageing pathway when interventions may be best targeted to promote health. The findings of this project will underpin the design for a complex intervention to be conducted in the future to improve the health outcomes of older people.
The proposed observational trial will collect substantial data concerning dietary intake documented by ALS patients complemented by the analysis of fatty acid distribution in erythrocyte lipids. Both data sets are related to disease status and progress.
The aim of the present study was to investigate the potential factors that determine preschool obesity in Al Ain, United Arab Emirates, and assess the effectiveness of a simple healthy lifestyle tool: Eat Right Emirates (ERE) adapted from the Ten Steps for Healthy Toddlers, produced in the UK by the Infant and Toddler Forum.
Most of the nation's serious chronic health challenges and causes of death, including diabetes, heart disease, cancer, and obesity, are directly linked to sub-optimal diet. Both poor diets and associated disease are disproportionately common in the Appalachian counties of eastern Kentucky, a region with stark health inequities, including elevated rates of obesity, overweight, and premature mortality. The purpose of this pilot study is to evaluate a multi-component intervention developed through community-based participatory research methods for improving access to healthy foods and enhancing dietary intake in eastern Kentucky. The intervention components evaluated in this study consist of a social marketing campaign delivered to middle and high schools to promote healthy snacking and water consumption, and a series of group cooking classes for adults.
This study is a prospective study of patients referred for coronary angiography at Bellevue Hospital Center and NYU Langone Medical Center. Subjects enrolled in this study will complete two one-page questionnaires, including information about diet, lifestyle, perceptions of health and perceived barriers to healthy lifestyles. Patients will be contacted at one and six months following their procedure to complete follow-up questionnaires to assess changes in diet and perceptions of their health after knowing the results of their coronary angiogram. The primary outcome measure will be change in dietary patterns/perception of lifestyle between baseline and one- month and six-month follow-up. Secondary measures will include association between dietary patterns/perception of lifestyle and degree of CAD and socioeconomic status.
This study aims to make a proper scientific assessment on the dietary intake and physical activity levels of a representative sample of the urban population of 8 Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Perú and Venezuela). The study was based on complex, multistage sample design, stratified by conglomerates, being all regions of each country represented, and random selection of main cities within each region according to probability proportional to size method. Sample will be stratified by gender, age (15 to 65 years old), and socioeconomic level. Socioeconomic levels will be balanced and divided in three strata (high, medium and low) based on national indexes used in each country. All the study sites are university-based and will adhere to a common study protocol for training, implementation of fieldwork, data collection and management, and quality control procedures to be performed simultaneously. All participants will be required to provide a written informed consent. A pilot study at small scale will be performed in each country in order to test procedures and tools involved in ELANS. Anthropometric variables, including body weight, height, waist, hip and neck circumferences will be measured according to a standardized protocol. Nutritional intake evaluation will be performed using two 24-hour dietary recalls, with 'multiple pass' procedure and a food frequency questionnaire. Nutritional data will be entered in Nutrition Data System for Research (NDS-R, Minnesota University) after a harmonization process between local foods and NDSR database. Physical activity and energy expenditure will be assessed by IPAQ-long version questionnaire and 7-day accelerometry.
Introduction Chronic disease is prevalent and costly in the U.S. (Tu & Cohen, 2009). Poor eating habit is one factor that account for risk of chronic disease (Arsand, Varmedal, & Hartvigsen, 2007). Smartphone technology has been promising to improve preventive health outcomes. However, its great potential has not been widely applied to people's eating behaviors and its impact is unknown. Professional and peer supports can improve health status (Elkjaer et al., 2010; Lorig et al., 1999; Perri, Sears, & Clark, 1993). However, the former is usually delivered didactically or passively with limited use of smartphones. There is also little evidence of the effect of peer support delivered by smartphones in the domain of healthy eating. This research aims to study what smartphone technology can do to upgrade professional and peer supports, and to evaluate the impact of these mobile-app enabled supports on people's behavior of healthy eating and user engagement. Hypotheses According to Social Cognitive Theory, we hypothesize the following: 1. Mobile-enabled self-monitoring approach improves users' healthy eating behaviors through improved self-efficacy 2. Professional support improves users' healthy eating behaviors through improved self-efficacy 3. Peer support improves users' healthy eating behaviors through improved self-efficacy 4. The amount of support is positively correlated with the change in behaviors and their determinants Experiment Design The hypotheses will be examined bya 4-month randomized field experiment. 375 subjects will be recruited and assigned to one of the five arms to receive the corresponding tool for diet management at no cost. Arm 1: a mobile App with both professional and peer support Arm 2: a mobile App with peer support only Arm 3: a mobile App with professional support only Arm 4: a mobile App without any support Arm 5: a non-mobile web App In addition to the App usage data, five surveys are conducted at baseline and the end of each month. Respondents will be compensated by $8 and a chance to win $200 for each completed survey. Interventions 1. All subjects receive the following interventions: an education package includes the importance of healthy eating, concept of MyPlate, personalized daily food plans; reminders throughout the study; goal setting capabilities; 2. Self-monitoring provided by an Android App: a heuristic approach inspired by MyPlate to record their food consumption which allows users to record their meals by images and doesn't require estimations in cups and ounces; daily reports and trend reports 3. Self-monitoring provided by the web App: a traditional approach to record their food consumption which requires estimations in cups and ounces, and no images are allowed; no daily reports and trend reports are provided 4. Professional support provided by a registered dietitian via the Android App: the supports include the following: 1. Reply to users' messages regarding healthy eating 2. Provide meal-specific comments on subjects' meal consumptions: one meal per week 3. Provide feedback on the subjects' consumption patterns: once per week 5. Peer support provided by other subjects via the Android App: the App provides platforms for subjects who have the same interest to communicate to each other. The actions the subjects can do in the platforms include: 1. Post images or texts related to healthy eating 2. Share meals with their ratings 3. Like/dislike others' posts 4. Comment on others' posts e Create groups which allow subjects who have the same interest to join Measurements 1. Dependent Variables 1. Eating behavior: a score of healthiness of a meal will be assigned by a dietitian. The scores obtained by the same subject along the experiment compose the subject's eating behavior 2. Engaging behavior: this is measured by the number of meals recorded by the subject in a week. The numbers for the same subject along the experiment compose the subject's engaging behavior 2. Independent Variables 1. Level of peer support: this will be measured by a score representing the number of posts, likes, and comments received and given by a subject in a week 2. Level of professional support: this will be measured by a score representing the number of messages or comments exchanged with the dietitian in a week 3. Mediator Variables: self-efficacy, outcome expectation, and impediments will be measured by survey instruments Data 1. User Survey: characteristics and perceptions 2. Mobile App: time, location, and contents of goal setting, meal entries, communications with professionals and peers 3. Web App: contents of goal setting and meal entries Analysis Confirmatory factor analysis and statistical modeling such as structural equation modeling and mixed models will be conducted to test our hypotheses.
The primary aim of this pragmatic randomized-controlled trial was to determine the effectiveness of a scalable 6-month intervention aimed at decreasing SSB consumption (SIPsmartER) when compared to a matched contact physical activity promotion control group (MoveMore).
