本文的目的是对中国预防或控制儿童和青少年体重过度增加的干预研究进行系统评价。以1990 - 2006年发表的干预性研究为关键词，检索中国全文数据库和万方数据库以及Medline和Meditext数据库。数据提取方面的研究质量，方法和干预措施的有效性。质量评估是使用以前建立的评估工具进行的。纳入了22项研究，其中17项在超重和/或肥胖儿童和/或青少年中进行。干预策略因研究而异，但大多数都集中在改善超重儿童和青少年的知识水平，身体活动水平和/或饮食。大多数研究报告了一个或多个研究结果的干预措施的有益效果，但所有研究都有严重或中度的方法学缺陷。本系统性综述确定的试验均未证明任何单一干预措施对预防中国大陆儿童和青少年超重和肥胖的有效性。未来的干预试验应解决本综述中发现的方法学缺陷。
The aim of this paper was to conduct a systematic review of intervention studies in China aimed at the prevention or control of excess weight gain among children and adolescents. Two Chinese databases (The China Full Text Database and Wanfang Database) and two English databases (Medline and Meditext) were searched with keywords for intervention studies published between 1990 and 2006. Data were extracted on aspects of study quality, methodology and effectiveness of interventions. Quality assessment was conducted using a previously established assessment tool. Twenty-two studies were included, of which 17 were conducted among overweight and/or obese children and/or adolescents. Interventions strategies varied across studies but the majority focused on improving the level of knowledge, physical activity levels and/or diet of overweight children and adolescents. Most studies reported a beneficial effect of the intervention with one or more of the study outcomes, but all of the studies had serious, or moderate, methodological weaknesses. None of the trials identified by this systematic review demonstrated convincing evidence of the efficacy of any single intervention for the prevention of overweight and obesity in children and adolescents from Mainland China. Future intervention trials should address the methodological weaknesses identified in this review.
