HEALTHY intervention: fitness, physical activity, and metabolic syndrome results.

ABSTRACT: This study aimed to assess the effect of the HEALTHY intervention on the metabolic syndrome (Met-S), fitness, and physical activity levels of US middle-school students.Cluster randomized controlled trial conducted in 42 (21 intervention) US middle schools. Participants were recruited at the start of sixth grade (2006) when baseline assessments were made, with post-assessments made 2.5 yr later at the end of eighth grade (2009). The HEALTHY intervention had four components: 1) improved school food environment, 2) physical activity and eating educational sessions, 3) social marketing, and 4) revised physical education curriculum. Met-S risk factors, 20-m shuttle run (fitness), and self-reported moderate to vigorous physical activity (MVPA) were assessed at each time point. Ethnicity and gender were self-reported. Obesity status (normal weight, overweight, or obese) was also assessed.At baseline, 5% of the participants were classified with Met-S, with two-thirds of the males and one-third of the females recording below average baseline fitness levels. Control group participants reported 96 min of MVPA at baseline with 103 min reported by the intervention group. There were no statistically significant (P < 0.05) differences in Met-S, fitness, or MVPA levels at the end of the study after adjustment for baseline values and confounders. There were no differences in any ethnic, obesity, or ethnic × obesity subgroups for either gender.The HEALTHY intervention had no effect on the Met-S, fitness, or physical activity levels. Approaches that focus on how to change physical activity, fitness, and Met-S using nonschool or perhaps in addition to school based components need to be developed.

Project description:Background:Metabolic syndrome (MetS) is a health disorder characterized by metabolic abnormalities that predict an increased risk to develop cardiovascular disease (CVD) and type 2 diabetes (T2DM). It can be resolved, and its complications reduced, by lifestyle interventions offered in primary care. The objectives of this study were to evaluate the impact of the exercise program of the CHANGE feasibility study on physical fitness and physical activity habits, and assess associations between changes in MetS components and cardiorespiratory fitness (CRF). Methods:In this analysis of 192 of the 293 adults with MetS in the overall study, the impact on physical fitness [aerobic capacity, muscular fitness and flexibility], and non-supervised physical activities was investigated over 12?months. In the CHANGE program, aerobic capacity, muscular fitness and flexibility were assessed at baseline, after 3?months of weekly supervised exercise, and following 9 additional months during which participants had one monthly session of supervised exercise. Additionally, CRF response was also examined in relation to changes in MetS components [fasting glucose, high-density lipoprotein (HDL) cholesterol, triglycerides, blood pressure, waist circumference (WC)]. Results:Fitness variables were significantly increased at 12?months with most of the improvements reached by 3?months (estimated VO2 max: 6 and 12%; partial curl-ups: 55 and 80%; push-ups: 50 and 100%; flexibility: 22 and 10% in men and women, respectively, p?<? 0.001). As expected, the duration and intensity of supervised aerobic physical activity increased during the first 3?months of supervision in both men and women, and remained unchanged for the duration of the program. The duration of non-supervised physical activities did not change during the program in men whereas an increase in manual work of moderate intensity was recorded in women between 3 and 12?months. In women, mean changes in WC were significantly greater among high VO2 max responders than low responders, between 0 and 12?months, as well as between 3 and 12?months (-?3.42?cm and?-?4.32?cm, respectively, p?<? 0.05). No associations were seen with MetS components in men. Higher intensity activities were maintained by both sexes at one year. Conclusion:Patients with MetS participating in the CHANGE lifestyle program improved physical fitness and physical activity habits by three months and maintained these gains over one year. Women who achieved a greater VO2 max increase had greater reductions in WC compared to low VO2max responders.

Project description:BackgroundMetabolic syndrome (MetS) has been diagnosed in adolescents and among the associated factors are low levels of physical activity, sedentary behavior over long periods and low cardiorespiratory fitness. However, specifically in adolescents, studies present conflicting results. The aim of the present study was to conduct a systematic review and meta-analysis of observational studies, in order to map the association between physical activity, sedentary behavior, cardiorespiratory fitness and MetS in adolescents.MethodsA search was performed in the databases PubMed, SPORTDiscus, LILACS and the Cochrane Library. For the meta-analysis, the odds ratio (OR) was calculated together with the respective confidence intervals (95% CI), in which the measures of effect were analyzed by dichotomous data (exposure variables) with MetS used as events.ResultsEighteen studies were included in the meta-analysis. Primary analysis demonstrated that low levels of physical activity (OR = 1.35 [1.03 to 1.79]; p = 0.03) and low cardiorespiratory fitness (OR = 4.05 [2.09 to 7.87]; p < 0.01) were significantly associated with the development of MetS, while for sedentary behavior, represented by screen time > 2 hours/day, a significant association was not identified (OR = 1.20 [0.91 to 1.59]; p = 0.20). Subgroup analyses demonstrated that the association between low physical activity and MetS was dependent on the use of the accelerometry technique (OR = 2.93 [1.56 to 5.47]; p < 0.01). Screen time > 2 hours/day was significantly associated with MetS only on weekends (OR = 2.05 [1.13 to 3.73]; p = 0.02). With respect to cardiorespiratory fitness, a significant association with MetS was found independent of the maximal oxygen uptake (VO2max) measurement method.ConclusionsLow levels of physical activity, low indices of cardiorespiratory fitness and sedentary behavior, represented by screen time > 2 hours/day on weekends, were significantly associated with the development of MetS in adolescence.
