Abstract
Effective obesity interventions in adolescent populations have been identified as an immediate priority action to stem the increasing prevalence of adult obesity. The purpose of this meta-analysis was to make a quantitative analysis of the impact of school-based interventions on body mass index during adolescence. Studies were retrieved from PubMed, Scopus, Science Direct and Web of Science databases. Results were pooled using a random-effects model with 95% confidence interval considered statistically significant. Of the 18 798 possible relevant articles identified, 12 articles were included in this meta-analysis. The global result showed a low magnitude effect, though it was statistically significant (N = 14 428), global e.s. = −0.055, P =0.004 (95% CI = −0.092, −0.017). Heterogeneity was low among the studies (I2 = 9.017%). The funnel plot showed no evidence of publication bias. The rank-correlation test of Begg (P =0.45641) and Egger’s regression (P =0.19459) confirmed the absence of bias. This meta-analysis reported a significant effect favoring the interventions; however, future research are needed since the reported the evidence was of low magnitude, with the studies following a substantial range of approaches and mostly had a modest methodological quality.

学校干预计划对青少年体重指数的影响:荟萃分析的系统评价。

摘要
在青少年人群中进行有效的肥胖干预已被确定为阻止成人肥胖流行率上升的当务之急。这项荟萃分析的目的是对青春期学校干预对体重指数的影响进行定量分析。从PubMed,Scopus,Science Direct和Web of Science数据库检索研究。使用随机效应模型合并结果,其中95%的置信区间被认为具有统计学意义。在确定的18798篇相关文章中,有12篇纳入了荟萃分析。总体结果显示出较低的幅度影响,尽管具有统计学意义(N  = 14428),全局es = -0.055,P  =0.004(95%CI = -0.092,-0.017)。在研究中,异质性较低(I 2 = 9.017%)。漏斗图未显示出版物偏倚的证据。Begg的秩相关检验(P  = 0.45641)和Egger回归(P  = 0.19459)证实没有偏倚。这项荟萃分析表明,干预措施具有显着效果。但是,由于报道的证据量很少,因此需要进行进一步的研究,这些研究采用了多种方法,而且大多数方法学质量均不高。
