Abstract

Background: Determine the effects of a multifactorial lifestyle intervention on physical activity (PA), BMI and health-related quality of life (QoL) in obese and overweight adolescents.

Methods: Nine schools in India were clustered randomly in a 12-month study with students allocated to a multifactorial intervention (MFI), or exercise only (EX) or control (CON) group. Participants were adolescents aged 11-16 years (n=671). In the MFI group, adolescents and their parents received lifestyle education using a validated booklet combined with a PA intervention for school students. The EX group received school-based PA only; the CON group continued regular activities. Primary outcomes were PA levels measured with the PAQ-A, and BMI; the secondary outcome was health-related QoL. A linear regression statistical model was used to analyse time, group effects and interactions, with Bonferroni correction for within-group differences at baseline (T0) and at 12-weeks (T1) (post-intervention), 6-month (T2) and 12-month (T3) follow-ups.

Results: Significant time and group effects observed for all groups with PA scores (p<0.001), with MFI group having largest increase in PA; with BMI (p<0.001) and MFI showing the least gain in BMI; and HRQOL (p<0.001), with MFI group showing greatest improvement in scores. There were significant increases in PA at T1 and T3 time-points with the EX group, and at T3 time-point only for MFI and CON, with MFI group showing largest increase in HRQOL scores. BMI increased significantly for all groups at T2 (MFI p=0.001, EX p<0.001) and T3 (p<0.001), while HRQOL increased significantly for both MFI and EX at both follow-ups (p<0.001).

Conclusions: School-based lifestyle MFI was more effective for improving PA, lifestyle behaviours and HRQOL than exercise alone for adolescents, although BMI was not reduced. MFI with PA could be an effective school-based approach for behaviour modification but BMI has limitations for measuring body composition changes.

务实的生活方式改变干预对印度乌杜皮肥胖和超重青少年体育活动水平和体重指数的影响：分组随机试验。

背景：确定多因素生活方式干预对肥胖和超重青少年的体育活动、体重指数和健康相关生活质量（QoL）的影响：确定多因素生活方式干预对肥胖和超重青少年身体活动（PA）、体重指数（BMI）和与健康相关的生活质量（QoL）的影响：在为期 12 个月的研究中，印度的九所学校被随机分组，学生被分配到多因素干预组（MFI）、仅锻炼组（EX）或对照组（CON）。参与者为 11-16 岁的青少年（671 人）。在多因素干预组中，青少年及其家长接受了生活方式教育，该教育采用了经过验证的小册子，并结合了针对在校学生的体育锻炼干预措施。EX组仅接受校内体育锻炼；CON组继续进行常规活动。主要结果是通过 PAQ-A 测量的 PA 水平和体重指数；次要结果是与健康相关的 QoL。采用线性回归统计模型分析时间、组别效应和交互作用，并对基线（T0）、12 周（T1）（干预后）、6 个月（T2）和 12 个月（T3）随访的组内差异进行 Bonferroni 校正：结果：所有组别在 PA 评分方面都观察到了显著的时间效应和组别效应（p 结论：校本生活方式 MFI 更有效：对青少年而言，校本生活方式 MFI 比单纯运动更能有效改善 PA、生活方式行为和 HRQOL，尽管体重指数（BMI）并未降低。MFI与PA可能是一种有效的校本行为矫正方法，但BMI在衡量身体成分变化方面存在局限性：CTRI/2019/04/018834 (30/04/2019).
