The primary goal of this project is to examine the short and long-term effects of an intervention focusing on three interrelated dimensions of health: improving sleep, increasing physical activity, and improving skills in emotion regulation. This intervention targets high-risk youth at a key neuromaturational period—early adolescence—when many individuals are experiencing new challenges to regulatory systems involved in sleep, activity, and emotion regulation. This maturational period is also a crucial time in the normal development of habits, skills, and proclivities in each of these domains. Thus, early adolescence presents unique opportunities for intervention targeting these three interrelated regulatory systems. Participants will include 200 9-13 year-old children who are siblings of children enrolled in one of three ongoing studies of vulnerability and resilience, whose families were initially identified on the basis of sociodemographic, child, and/or family risk or are recruited thru local Family Centers. Children will be selected as having difficulties in at least one of these domains (sleep, sedentary behavior, or emotion regulation) and then randomly assigned to either a control or intervention group. All families will receive baseline, one- and two-year follow-up assessments of child sleep, physical activity, and emotion regulation. Families in the intervention group will have the opportunity to receive feedback and intervention services on these three child domains and other parenting and family issues (e.g., parent involvement, parent self-care, school problems) following the initial assessment and the one-year follow up. The intervention will involve the parent and target youth receiving feedback about the child's current status in these areas and family functioning. If desired, the family will also participate in follow-up meetings with the parent and/or target youth to improve the youth's sleep, physical activity, and/or emotion regulation skills, as well as aspects of the family environment. The investigators hypothesize that the intervention will be associated with improvements in sleep, physical activity, and emotion regulation among those in the intervention group, as well as improvements in measures of social, behavioral, and affective function. Finally, the investigators will explore the possibility that increases in parental involvement mediate some of the changes found in child sleep, physical activity, and emotion regulation.
The main objective of this study is to test an intervention to increase the physical activity of medical residents, an employee population with little time for exercise. Specifically, the aims of this study are: 1. To determine if providing medical residents with an activity device that measures steps, distance, and calories burned and tracks this information over time on a website increases residents' physical activity levels as measured by number of steps per day compared to a control group using a blinded activity device (no feedback). 2. To determine if an unblinded team competition using the activity device directly following the randomized phase increases residents' activity level compared to baseline. 3. To determine if activity level is associated with change in weight during the residency year. 4. To determine if the average hours of sleep per week is associated with changes in weight and with activity level.
The goal of this pilot randomized controlled trial is to evaluate whether financial incentives and peer networks delivered through a novel computer platform utilizing a digital pedometer-internet interface can effectively encourage sustained increases in walking among older adults.
The primary purpose of this study is to assess the efficacy of the mobile phone-based physical activity intervention on increasing physical activity compared to the control group.
Researchers from Oregon Health & Science University have developed a science-based, team-centered, scripted peer-taught program for fire fighters improving diet and exercise behavior while reducing injury rates and costs. Those investigators are partnering with local law enforcement agencies in Oregon and SW Washington to adapt, apply and assess this work-based program among a new high risk group to improve the health and safety of law enforcement officers (LEOs). Fire fighters' work structure is a natural fit for a team-centered format, and teammates' social support appeared to partially mediate the intervention's positive outcomes. Although conducive to team formation, LEOs' work lacks the established team structure of fire fighters. This proposal will apply the team-centered intervention to LEOs and in the process, learn more about teams as vehicles of health behavior change, and their relationship with outcomes and other potential mediating variables in a multilevel ecological analytic framework.
The purpose of this study is to evaluate the effectiveness of a recreational physical activity intervention (RPAI) for reducing the prevalence of overweight/obesity and other cardiovascular risk factors
Recent studies have suggested that prolonged daily sitting time may in itself have a negative effect on health, even in people who engage in daily physical activity. The aim of the present study is to explore whether individually tailored lifestyle counselling aimed at reducing TV-viewing and other sedentary activities during leisure time and at work, can reduce sitting time and waist circumference, weight and blood pressure; and improve serum lipid levels. From a population-based health survey, 150 adult men and women with more than 3.5 hours of daily leisure time sitting time are recruited and randomly assigned to 1) an intervention group or 2) a control group. The intervention group will participate in 4 individually tailored lifestyle intervention sessions focussing on reduction of daily sitting time. The control group will receive no intervention.
The specific aims of the proposed study are: - 1. To determine if web-based Motivational Interviewing (MI) is effective, compared to an informational web-based comparison group, in enhancing physical activity (PA) participation; and - 2. To assess the mechanisms by which web-based MI enhances PA through changes in targeted cognitive mediators. The specific hypotheses of the study include that: - Hypothesis 1: Web-based MI will increase PA; - Hypothesis 2: Web-based MI will lead to stage progression in the direction of increased readiness to participate in PA; - Hypothesis 3: Web-based MI will influence theoretically identified cognitive variables; - Hypothesis 4: Cognitive variables will mediate increases in PA participation.
The objective of this project is to validate the proposed smartphone-based activity monitor and to test its use for Motivational Interviewing based counseling for physical activity in Chronic Obstructive Pulmonary Disease (COPD).
