Abstract

Background and Objectives

Childhood obesity is a global public health issue with strong familial and intergenerational transmission. However, existing syntheses often overlook the active role of parents and fail to assess outcomes beyond the child. This systematic review and meta-analysis specifically investigate the effects of family-based interventions, which position parents as active co-agents of change, on health outcomes for both children with obesity and their parents.

Methods

A systematic review and meta-analysis were conducted. Six databases were searched for randomized controlled trials (RCTs) targeting children with obesity and at least one family member. Primary outcomes were children's BMI z-score and parental BMI; secondary outcomes included other adiposity measures and dietary behaviors. Outcomes for both children and parents were synthesized. Subgroup analyses were conducted based on intervention characteristics. Risk of bias was assessed using RoB 2, and evidence certainty was evaluated using GRADE.

Results

Twenty RCTs with 1740 participants were included in the meta-analysis. The interventions demonstrated a significant reduction in children's BMI z-score. Additional benefits were observed for long-term BMI z-score and percentage of total body fat. The most effective interventions commonly integrate health education, behavioral strategies, and motivational support. Subgroup analyses indicated that interventions positioning parents as active co-participants, rather than mere supporters, yielded larger effects. However, no significant effects were found on parental BMI.

Conclusion

This study demonstrates that family-based interventions can confer significant benefits for children with obesity. Their success hinges on strategically framing parents as active co-agents and integrating motivational strategies.

以家庭为基础的儿童肥胖干预对父母和后代结局的影响：系统回顾和荟萃分析。

背景和目的：儿童肥胖是一个全球性的公共卫生问题，具有很强的家族性和代际遗传性。然而，现有的综合往往忽视了父母的积极作用，未能评估孩子以外的结果。本系统综述和荟萃分析专门调查了以家庭为基础的干预措施的影响，这些干预措施将父母定位为积极的变革共同推动者，对肥胖儿童及其父母的健康结果产生影响。方法：进行系统综述和荟萃分析。在6个数据库中检索了针对肥胖儿童及其至少一名家庭成员的随机对照试验（rct）。主要结局为儿童BMI z-score和父母BMI；次要结果包括其他肥胖测量和饮食行为。对儿童和家长的结果进行综合分析。根据干预特征进行亚组分析。使用RoB 2评估偏倚风险，使用GRADE评估证据确定性。结果：meta分析纳入20项随机对照试验，共1740名受试者。干预显示儿童BMI z-score显著降低。额外的好处观察到长期BMI z-score和总体脂百分比。最有效的干预措施通常包括健康教育、行为策略和动机支持。亚组分析表明，将父母定位为积极的共同参与者，而不仅仅是支持者的干预措施产生了更大的效果。然而，没有发现对父母的BMI有显著影响。结论：本研究表明，以家庭为基础的干预可以给肥胖儿童带来显著的好处。他们的成功取决于从战略上把父母塑造成积极的合作代理人，并整合激励策略。

期刊介绍： Obesity Reviews is a monthly journal publishing reviews on all disciplines related to obesity and its comorbidities. This includes basic and behavioral sciences, clinical treatment and outcomes, epidemiology, prevention and public health. The journal should, therefore, appeal to all professionals with an interest in obesity and its comorbidities. Review types may include systematic narrative reviews, quantitative meta-analyses and narrative reviews but all must offer new insights, critical or novel perspectives that will enhance the state of knowledge in the field. The editorial policy is to publish high quality peer-reviewed manuscripts that provide needed new insight into all aspects of obesity and its related comorbidities while minimizing the period between submission and publication.
