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.
Oral administration of betaglucosylceramide was shown effective in reducing inflammation in animal models and was found safe in humans.
The purpose of this study is to evaluate quality of life, degree of disability, treatment patterns and economic impact of hand and knee Osteoarthritis and Rheumatoid Arthritis in Mexico.
Auditory motor-coupling has been shown to induce neural-entrainment that can synchronize walking-pace with sonic tempo. The extent to which acoustical-motor entrainment can induce longer-term changes to physical activity behaviours remains unclear. Cardiac rehabilitation is essential and is associated with irrefutable mortality benefits for patients following an acute cardiac event. Randomized clinical trials have demonstrated a 25-50% improvement in survival as compared to controls; however, as many as 50% of patients will dropout of such programs prior to completion, which undermines these morbidity and mortality benefits (37; 54). Research exploring ways to improve compliance to such programs has suggested that the incorporation of music and other such holistic, patient-centered interventions into a rehabilitation/exercise program is associated with improved motivation, endurance and satisfaction amongst cardiac rehabilitation participants. The MAINTAIN study has been designed to conduct a feasibility evaluation on the effects of a preference-based music intervention on adherence to the cardiac rehabilitation program at Toronto Rehabilitation Institute. The primary objective of the trial is to evaluate the feasibility of the implementation of such a protocol within the context of the program. This is a two-arm, block 2:1 randomized trial. 35 patients participating in cardiac rehabilitation at Toronto Rehabilitation: Cardiac Rehabilitation and Secondary Prevention Program will be recruited and participants will be randomized into: 1) control (standard, usual care); and, 2) music intervention. The randomization process employed will be a blocked 2:1 strategy, whereby subjects are randomized to the music treatment arms 2:1. All those patients randomized into arm 2 will be equally randomized into either (2) preference-based music intervention, (3) preference-based music enhanced with RAS. The primary outcome measure will be weekly physical activity over a 3 month duration as measured using tri-axial accelerometers. We will also analyze the impact of a preference-based music intervention based on audio playlist utilization, self-reported sitting times ,exercise-times, on-site attendance to the cardiac rehabilitation program (attendance), peak oxygen uptake (VO2) (stress-test), and self-efficacy levels (self-efficacy questionnaires). These measures will be collected and analyzed throughout the course of the intervention (3 months).
This study is a randomized controlled pilot of a work site weight control intervention. The purpose of the pilot is to obtain preliminary data for future NIH submissions. Four work sites were identified through a multistage recruiting process. Work sites were randomized to either the intervention group, which will receive the intervention immediately following randomization or the control group which will receive a shortened intervention over a 1-month period, 6 months after the active intervention sites have completed their program. The intervention will consist of a variety of activities conducted over a 6 month period, that are overseen by a work site-Tufts oversight group, including the following optional elements: For overweight and obese individuals, regular support groups for weight loss and prevention of weight regain. For all work site employees irrespective of weight, handouts and posted informational resources on healthy eating, monthly lunchtime seminars, and food sampling to facilitate healthy eating patterns for prevention of weight gain. Basic online assessments on health and nutrition will be carried out at baseline (week 0) and 24 weeks in all work site employees willing to provide information. More detailed online and in-person assessments will be performed throughout the 24-week study period in the weight loss support group participants (intervention sites) and individuals intending to enroll in the support group (control sites).
