The rates of pediatric obesity in the U.S. are highest among Hispanics. There is no existing meta-analysis of the effects of obesity interventions among Hispanic youth. This systematic review and meta-analysis assesses the effects of obesity prevention and treatment interventions on Hispanic youth's weight status and lifestyle behaviors.
PubMed, PsycINFO, and Scopus were searched between January 1, 2000 and October 30, 2020. Interventions with ≥50% Hispanic youth aged 0-18 years were included. Using a weighted inverse-variance procedure, fixed-effects and random-effects models were run for an overall effect size on the basis of the Q test statistic. Hedges' g was calculated for outcomes of interest between baseline and postintervention separately for studies with multiple versus single conditions. Continuous and categorical moderators were also examined.
A total of 1,103 articles were screened, of which 117 were included in the narrative synthesis and 105 in the meta-analysis (n=49,276 youth). The overall effects for RCT/quasi-experimental studies on BMI status (g= -0.15, SE=0.03, 95% CI= -0.20, -0.10), waist circumference (g= -0.15, SE=0.10, 95% CI= -0.35, -0.05), physical activity (g=0.12, SE=0.05, 95% CI=0.03, 0.22), fruit and vegetable intake (g=0.08, SE=0.02, 95% CI=0.03, 0.12), and sugar-sweetened beverage intake (g= -0.07, SE= 0.03, 95% CI= -0.13, -0.01) were small. Intervention effects varied by participant developmental stage, SES, study setting, and lifestyle behavior target.
Beyond developing more impactful interventions to address obesity among Hispanic youth, findings highlight the need for targeted policies and more easily disseminable interventions that can spread small effects across a population for maximal public health impact.
美国的儿童肥胖率在西班牙裔中最高。目前还没有对西班牙裔青年肥胖干预效果的荟萃分析。本系统评价和荟萃分析评估了肥胖预防和治疗干预对西班牙裔青年体重状况和生活方式行为的影响。
在 2000 年 1 月 1 日至 2020 年 10 月 30 日期间，检索了 PubMed、PsycINFO 和 Scopus。纳入了至少有 50%西班牙裔青少年（0-18 岁）的干预措施。根据 Q 检验统计量，使用加权倒数方差程序，对整体效应大小进行固定效应和随机效应模型分析。对于具有多个与单一条件的研究，分别计算了基线和干预后之间感兴趣的结局的 Hedges'g。还检查了连续和分类的调节因素。
共筛选出 1103 篇文章，其中 117 篇进行了叙述性综合分析，105 篇进行了荟萃分析（n=49276 名青少年）。随机对照试验/准实验研究的总体效果为 BMI 状态（g=-0.15，SE=0.03，95%CI=-0.20，-0.10）、腰围（g=-0.15，SE=0.10，95%CI=-0.35，-0.05）、身体活动（g=0.12，SE=0.05，95%CI=0.03，0.22）、水果和蔬菜摄入量（g=0.08，SE=0.02，95%CI=0.03，0.12）和含糖饮料摄入量（g=-0.07，SE=0.03，95%CI=-0.13，-0.01）较小。干预效果因参与者发育阶段、社会经济地位、研究环境和生活方式行为目标而异。
除了制定更有影响力的干预措施来解决西班牙裔青少年的肥胖问题外，研究结果还强调需要制定有针对性的政策和更易于传播的干预措施，以便在人群中传播微小的效果，从而产生最大的公共卫生影响。
