Filter by: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 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).
Obesity has been linked to the development of multiple cancers, and to poorer prognoses and higher mortality rates for certain pediatric and adult cancers. Preventing obesity is therefore a major strategy to prevent new cases of cancer and to decrease cancer related morbidity and mortality. In the US, childhood obesity is on the rise. Since childhood obesity strongly tracks into adulthood this epidemic among children greatly increases the risk of obesity and presumably cancer in adulthood. As a result, preventing childhood obesity has been selected as a major public health goal to reduce the risk and sequelae of obesity and cancer in the US. Moreover, television (TV) viewing has been identified as a major risk factor for childhood obesity and US children spent more time watching TV than any other activity except sleep. TV viewing contributes to excess weight gain by decreasing physical activity and increasing caloric intake. The American Academy of Pediatrics (AAP) has issued national guidelines for parents to limit their children's total entertainment media time to no more than 1 to 2 hours of quality programming per day for children greater than 2 years of age. Low-income and minority children were at greater risk for exceeding this recommendation. Few published interventions have been successful in decreasing TV viewing in children and only one was successful among preschool children. This intervention, "Fit 5 Kids" (i.e. fit by age 5 years), was a preschool curriculum designed to decrease TV viewing via age-appropriate lessons taught to the children by research staff. The curriculum also included a take-home component consisting of a newsletter with ideas for parent (for this grant, defined as the adult most responsible for the child's care, usually the mother) and child activities that complemented the school lesson plans. Although most behavioral interventions for preschoolers target parents rather than children, this curriculum was one of the few successful interventions targeted directly at children. However, Fit 5 Kids was not designed for or evaluated among Hispanic preschool children, the subpopulation of preschool children most severely affected by obesity. Moreover, no published intervention has successfully reduced both TV viewing and excess weight gain in any preschool population. In order to fill this gap, the investigators propose to evaluate a culturally adapted Fit 5 Kids TV reduction curriculum among Hispanic preschool children enrolled in the Head Start Program. Fit 5 Kids is the TV reduction component of the Brocodile the Crocodile health promotion program. The overall goal of Fit 5 Kids is to teach the preschoolers to decrease their TV watching and encourage alternative activities such as family meals and active playtime. The primary goal of this research plan will be to conduct a pilot group randomized controlled trial evaluating the effectiveness of the adapted curriculum to reduce TV viewing and excess weight gain in low income, Hispanic preschool children To achieve the project goals, the investigators Specific Aim includes: 1. To successfully recruit forty-eight 3-5 year old Hispanic children from 4 Head Start centers each year for 3 years and conduct a group randomized controlled study of the adapted Fit 5 Kids curriculum to evaluate its effectiveness in reducing TV viewing and excess weight gain in Hispanic preschool children. The Primary Hypothesis to be tested includes: H1. The culturally adapted Fit 5 Kids curriculum will reduce TV viewing and excess weight gain among Hispanic preschool children.
Although a number of studies have examined the effects of Tai Chi in older adult populations, few have methodically assessed its effects on vitality, fatigue and physical activity. Some studies have shown that fatigue relates to negative mood and poor health-related quality of life in older persons. Tai Chi is an ancient Chinese form of calisthenics that utilizes the body's internal energy (chi), mind, and breathing; which may be a useful exercise for older adults in increasing their activity level. A twenty-four of Yang style of Tai Chi is a simple form of Tai Chi that is particularly well-suited for older adults. This proposed study to investigate the effects of a Tai Chi intervention on decreasing fatigue level, and increasing level of activity in healthy older adults. The investigators research group has focused on the Tai Chi as a strategy to reduce stress and improve sleep, and their preliminary evidence suggest it strongly affects energy level and vitality. The investigators are focused on taking this intervention into the community testing its efficacy. The investigators preliminary data shows that Tai Chi is of benefit to older adults; however, this study will test whether their research findings are generalizable to community settings. Tai Chi-naïve participants from Culver City Senior Center will receive a 10-week Tai Chi. The investigators will compare this group to a wait-list control group. All subjects will receive a packet of questionnaires of pre- and post-intervention vitality, fatigue and health-related quality of life. Subjects will also be given an activity monitor to wear for 2 days before they start the Tai Chi class and for 2 days after they complete the class, to determine if there is a change in general physical activity level.
Purpose: Examine the effectiveness of cancer center-based physical activity counseling on physical activity rates and quality of life in breast cancer survivors. Hypothesis: Participants in the intervention group will indicate greater step counts and quality of life at the end of the intervention compared to the control group
The objective of the study is to evaluate the efficacy of an intervention on food habits and physical activity in school-age children.
The purpose of this study is to assess whether a 6-month multilevel physical activity intervention can significantly increase physical activity levels in sedentary adults, 65 and older, living in Continuing Care Retirement Communities (CCRCs). Sedentary residents (N=320)in 16 CCRCs will receive the multilevel MIPARC intervention or a control health education program for 6 months. A group randomized control design will be employed with site as the unit of randomization. The intervention is delivered through group sessions, phone calls, printed materials, tailored signage and mapping and targeted peer led advocacy efforts.
The investigators propose a randomized controlled trial based on the Social Networks for Activity (SNAP) Model to evaluate: (1) the effectiveness of an internet-based fitness walking program delivered to patients with risk factors for cardiovascular disease and stroke; and (2) the contribution of social support networks to enhancing the effectiveness of the internet-based fitness walking program. The investigators will recruit 308 patients who are sedentary and have risk factors for cardiovascular disease and randomly assign them to one of the following groups: 1. Internet-based fitness walking program (WalkLink); 2. Internet-based fitness walking program plus additional social network intervention (WalkLink+); and 3. Minimal treatment control. The primary specific aims of this study are to: 1. Evaluate the effects of WalkLink and WalkLink+ relative to a minimal treatment control group on change in: physical activity, aerobic fitness, blood pressure, body composition, and body mass index (BMI), from baseline to posttest, and at 6-month follow-up. 2. Compare the differential effectiveness of WalkLink+ to WalkLink on change in: physical activity, aerobic fitness, blood pressure, body composition and BMI from baseline to posttest, and at 6-month follow-up. 3. Evaluate the mediator and moderator effects of selected individual-level self-management skills (goal setting, planning, self-monitoring), social support variables (number of activity partners, social cues for walking, social praise/reinforcement), and physical-ecological variables (neighborhood walkability, physical cues for walking) on WalkLink and WalkLink+ treatment outcomes.
