Filter by:Background. The prevalence of metabolic syndrome (MetS) has been increasing, and its risk is positively correlated with age. Due to ageing society in Taiwan, how to treat metabolic syndrome and decrease the complications is an important health issue. Relatively few studies have been focusing on the effects of exercise training in patients with MetS with long-term follow-up. Recently, high-intensity interval training or aerobic interval training (AIT) consisting of high intensity separated by active recovery has been proposed to be more effective than isocaloric continuous moderate-intensity exercise (CME) in raising exercise capacity (VO2max) in some specific patient population. Purpose. The purposes are to (1) compare the effects of 16-week CME and AIT on reducing the numbers of metabolic risk factors in patients with MetS and the prevalence. Hypothesis: 16-week AIT reduces more metabolic risk factors than CME in patients with MetS. Methods. This study will be a multiple-center trial. One hundred and twenty patients, aged ≥45 years, with a diagnosis of MetS for each center will be recruited. Subjects will be randomly assigned to either control, CME, or AIT group after baseline assessments. Participants in control group will receive usual care and the others in two exercise groups will undergo 16-week exercise training. All subjects will receive 16-week, 6-month and 1-year follow-ups including blood test, body composition (body mass index, waist circumference), pulse wave velocity, and maximal exercise testing. Statistical analysis will be conducted using SPSS 11.5, p < 0.05 indicating statistical significance. Data will be presented in mean±standard deviation or number (percentile) with intention-to-treat analysis. Chi-square test or one-way Analysis of Variance (ANOVA) will be used to compare whether there are between-group differences at baseline. Two-way repeated measures ANOVA and post-hoc test will be performed to examine time and group effect if there is interaction effect, otherwise Bonferroni will be used. The subgroup analysis between MetS and n-MetS after training will be performed using the same statistical methods.
South Asian (SA) women living in Ontario have a higher risk of developing type 2 diabetes and coronary heart disease (CHD) compared to the general population. Various explanations for these differences have been established, one of which is based on low levels of physical activity in people of SA origin, particularly in Muslim women. This pilot trial will test the feasibility, acceptability and effectiveness of a Mosque-based exercise and educational intervention designed for SA Muslim women. 1. What is the feasibility of a mosque-based intervention to promote physical activity that is culturally and gender sensitive to South Asian Muslim women? 2. What is the acceptability of a mosque-based intervention to promote physical activity that is culturally and gender sensitive to South Asian Muslim women? 3. What is the effectiveness of a mosque-based intervention to promote physical activity that is culturally and gender sensitive to South Asian Muslim women?
A minimum of 450 healthy individuals (62-70 years old) will be recruited. Each individual will be randomized into one of three groups stratified according to gender (M/F), BMI (≤28/>28), and 30 sec chair stand (≤11/>11). The three groups are Heavy resistance training (n=150), moderate intensity training (n=150), and control (n=150, no training). Assessments will be performed at baseline, after 12 months of intervention. Furthermore, follow up will be performed after 2,4,7, and 10 years. The primary outcome is change in leg extensor power after the intervention and during follow up. The primary hypothesis is that by applying the intention-to-treat analysis, the moderate intensity training group will increase leg extensor power just as much as the heavy resistance training group. The two training groups will increase muscle power more than the control group.
The purpose of the study is: 1) To evaluate the efficacy and feasibility of an SMS reminder intervention for promoting an health-related exercise programme (myPAtHS) among older Malaysian adults, in a randomized controlled trial (RCT). Hypothesis: Frequency and duration of the exercise programme execution will be higher for the SMS reminder condition compared to the programme only condition. The effect may be reduced from post- to follow-up measurement (24 weeks after baseline and 12 weeks after post-measurement) but all outcomes will remain significantly higher at 24 weeks.
The purpose of the GRECO study were to: a) to provide national data on overweight and obesity prevalence in a representative sample of primary schoolchildren aged 10-12 years old, b) to identify those socio-economic, demographic factors, as well as dietary and physical activity habits and familial characteristics that are associated with childhood and preadolescent overweight and obesity, c) to identify lifestyle and dietary patterns that are associated with elevated blood pressure levels and dietary sodium intake.
More than 530,000 individuals work as US Correctional Officers (COs) responsible for overseeing the approximately 1.6 million offenders who are incarcerated at any given time in the United States. Prison work is regarded as one of the most difficult occupations with CO's having one of the highest nonfatal injury rates of all U.S. occupations. The few studies done on CO's show high levels of stress, cardiovascular disease, high job burnout, increased sick leave rates and absenteeism, and decreased quality of life leading to premature illness/injury and high employer healthcare costs. Many of these conditions could be prevented by specific training activities and healthier lifestyles. The investigators wish to test a worksite-based, health promotion curriculum in COs with the overall hypothesis that the program will improve health and decrease injuries. The program proposed would be the first occupational intervention to improve the safety, and emotional and physical health of those who are charged with the complex task of prison work protecting the investigators communities. If successful, this proposal would result in an exportable, practical occupational safety and health program applicable for use by local, state, and federal correctional facilities.
The prevalence of overweight and obesity are increasing worldwide. In the U.S., approximately 85,000 new cancer cases per year are related to obesity. Understanding lifestyle behaviors, their causes, and relations to cancer are critical. Where people spend their time during the day may be related to their risk of getting cancer. This project will assess behaviors in different locations across the day and relate exposure to different environments to biological outcomes.
The purpose of this study is to develop and evaluate adaptive goal setting and feedback interventions (Adaptive Interventions) to promote physical activity behaviors and compare it to static physical activity interventions (Static Interventions) using two levels of goal setting (Adaptive Goals vs. Static Goals) and two levels of reinforcement procedures (Praise/Rewards and No Praise/Rewards) in a 2 x 2 factorial randomized controlled trial. All four groups will receive the intervention via a semi-automated text message system developed by the investigators study team. The primary aim of this study will be to: 1. Evaluate whether the adaptive interventions result in greater change in physical activity (pedometer-measured steps/day) compared to the static Intervention groups. HYPOTHESES: Participants in the adaptive interventions will increase their steps/day more than participants in the Static Intervention groups. The Adaptive Goals and Reinforcement Group will outperform the other 3 groups. The secondary aims of this study will be to: 2. Evaluate the effectiveness of the adaptive and static goal interventions in improving anthropometric, cardiovascular fitness, and cardiometabolic risk factors. HYPOTHESES: Participants in the adaptive interventions will show greater improvements in fitness, lean and fat body mass, and serum biomarkers than participants in the Static Intervention groups. The Adaptive Goals and Reinforcement Group will outperform the other 3 groups. 3. to assess participants' satisfaction with the overall program.
The purpose of this study it to determine if a promotora-led intervention that takes a comprehensive, multi-level, community-based approach to promoting physical activity (PA) is effective among a particularly underserved segment of Latinas. We hypothesize that Latinas in the promotora-led PA Intervention will significantly increase minutes per week of moderate-to-vigorous physical activity (MVPA) compared to Latinas in the attention-control group.
Sedentary older adults are more likely to develop physical function impairments than active older adults. Physical function measured by slow usual gait speed predicts the risk of future falls, disability, institutionalization and mortality. Behavioral physical activity interventions have improved physical activity and physical function, but have not generally been implemented where they may have the most impact -- primary care settings. In part, this is due to the limited time and training for clinical staff to screen for physical function impairment and to treat with physical activity counseling. The proposed scientific goal is to overcome these barriers by adapting an evidence-based screening tool and telephone-based physical activity intervention into primary care settings. Aim1: Among older adults who screen positive for physical function impairment, to determine the estimated intervention effect size of a 12-week behavioral intervention on physical activity and physical function. Hypothesis 1a: Physical activity levels will increase more in the intervention vs. usual care group. Hypothesis 1b: Physical function will increase more in the intervention vs. usual care group. Aim 2: Among Aim 1 participants and clinical staff who deliver the functional screening and Aim 1 intervention, to evaluate standard implementation science process metrics of reach, acceptability, and implementation
