社会经济地位（SEP）与肥胖之间的关系（通过体重指数（BMI）（一种身高体重指标）测量）已在儿童中进行了广泛审查，结果显示，弱势SEP与高收入国家（HIC）较高的BMI之间存在一致的关联。中等收入国家（MICs）的BMI较低。脂肪质量（FM）是肥胖的更准确测量指标，而无脂肪质量（FFM）并不被BMI所捕获，但已被证明从童年到成年都会跟踪，并且对晚年的心血管健康和功能结果很重要。体成分与SEP的关系尚不清楚，本文系统综述了儿童期SEP与体成分的关系。根据PRISMA指南进行系统评价。该方案已在PROSPERO（CRD 42019119937）进行了预注册。原始的研究在英语中，检查SEP和儿童身体成分之间的关联，包括在内。对三个数据库进行了电子检索。两名独立的审查员进行了筛选、数据提取和质量评估。由于结果的异质性，进行了叙述性综合。根据SEP、性别、身体成分测量和国家收入水平调查了异质性结果。共收录了50篇论文，其中大部分来自高收入国家。没有来自低收入国家的论文。在儿童期的不利因素与更大的FM和更低的FFM在HIC，但与更低的FM和更低的FFM在MICS.When措施的FFM指数的高度被使用，没有证据表明与SEP.In HIC，更多的研究报告之间的关联不利SEP和更高的FM女孩相比，男孩。在高收入国家中，FM的不平等现象很明显，在中等收入国家中则相反，其趋势与BMI的不平等现象相似。身高的不平等对于理解实况调查中的不平等可能很重要。
The relation between socioeconomic position (SEP) and obesity measured by body mass index (BMI), a measure of weight for height, has been extensively reviewed in children, showing consistent associations between disadvantaged SEP and higher BMI in high-income countries (HICs) and lower BMI in middle-income countries (MICs). Fat mass (FM), a more accurate measure of adiposity, and fat-free mass (FFM) are not captured by BMI, but have been shown to track from childhood to adulthood, and be important for cardiovascular health and functional outcomes in later life. It is not clear whether body composition is associated with SEP. We systematically reviewed the association between SEP and body composition in childhood. A systematic review was carried out following PRISMA guidelines. The protocol was pre-registered with PROSPERO (CRD42019119937). Original studies in the English language, which examined the association between SEP and body composition in childhood, were included. An electronic search of three databases was conducted. Two independent reviewers carried out screening, data extraction and quality assessment. Due to heterogeneity in results, a narrative synthesis was conducted. Heterogeneity in findings according to SEP, sex, body composition measure and country income level was investigated. 50 papers were included, the majority from HICs. No papers were from low-income countries. Disadvantage in childhood was associated with greater FM and lower FFM in HICs, but with lower FM and lower FFM in MICs. When measures of FFM indexed to height were used there was no evidence of associations with SEP. In HICs, more studies reported associations between disadvantaged SEP and higher FM among girls comparative to boys. Inequalities in FM are evident in HICs and, in the opposite direction, in MICs and follow similar trends to inequalities for BMI. Inequalities in height are likely important in understanding inequalities in FFM.
