Impact of physical activity interventions on anthropometric outcomes: systematic review and meta-analysis.

ABSTRACT: Considerable research has tested physical activity (PA) interventions to prevent and treat overweight and obesity. This comprehensive meta-analysis synthesized the anthropometric effects of supervised exercise interventions and motivational interventions to increase PA. Eligible intervention studies included healthy participants with reported anthropometric outcomes [e.g., body mass index (BMI)]. Extensive searching located 54,642 potentially eligible studies. We included data from 535 supervised exercise and 283 motivational interventions in our syntheses, which used random-effects analyses. Exploratory moderator analyses used meta-analytic analogues of ANOVA and regression. We synthesized data from 20,494 participants in supervised exercise and 94,711 undergoing motivational interventions. The overall mean effect sizes (ES, d) for treatment versus control groups in supervised exercise interventions were 0.20 (treatment vs. control within-group comparison) and 0.22 (between-group comparison). The ES of 0.22 represents a post-intervention BMI of 26.7 kg/m(2) for treatment participants relative to 27.7 kg/m(2) for controls. The corresponding mean ES for motivational interventions was significantly smaller (d = 0.09 for between group, d = 0.10 for treatment vs. control within-group). Control group within-group comparisons revealed slightly worsening anthropometric outcomes during study participation (d = -0.03 to -0.04). Moderator analyses identified potential variables for future research. These findings document significant improvements in anthropometric effects from both supervised exercise and motivational interventions.

Project description:OBJECTIVES:Compared with sighted individuals, people with visual impairment have a higher prevalence of chronic conditions and lower levels of physical activity. This review aims to systematically review physical activity interventions for those with a visual impairment and to assess their effectiveness. DESIGN:A systematic review of articles reporting physical activity interventions in visually impaired individuals was conducted. Medline, EMBASE, The Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, SPORTDiscus and the Physiotherapy Evidence Database were searched in August 2018. Meta-analyses were conducted on randomised controlled trials with the same outcome measure. SETTING:Most interventions were conducted in a group setting, with some including an at-home, self-directed component. PARTICIPANTS:Following identification of a recent systematic review of physical activity interventions in children, our review focused on adults aged 18 years and older with a visual impairment. PRIMARY AND SECONDARY OUTCOME MEASURES:Outcomes included measures of balance, mobility, mental well-being (eg, quality of life), number of falls, muscle strength, flexibility and gait. RESULTS:Eighteen papers from 17 studies met inclusion criteria. Physical activity components include falls prevention and/or balance-based activities, walking, tai chi, Alexander Technique, Yoga, dance, aerobics and core stability training. Significant results in favour of the intervention were reported most commonly in measures of functional capacity (9/17 studies) and in falls/balance-related outcomes (7/13 studies). The studies identified were generally small and diverse in study design, and risk of bias was high across several categories for most studies. Meta-analyses indicated non-significant effects of the included interventions on the Timed Up and Go, Chair Sit Test and Berg Balance Scale. CONCLUSIONS:Physical activity interventions in individuals with visual impairment incorporating activities such as tai chi, Yoga and dance can have positive results, particularly in physical measures such as mobility and balance. However, when performing a meta-analysis of randomised controlled trials, the evidence for effectiveness is less clear. More studies with larger sample sizes, stronger designs and longer follow-up periods are needed. PROSPERO REGISTRATION NUMBER:CRD42018103638.
