The relationship between sleep duration and obesity has been the focus of numerous investigations. This systematic review and meta-analysis of prospective cohort studies aimed to assess the relationship between sleep duration, abdominal obesity, and body composition.
PubMed, Scopus, and Web of Science were searched until February 2024. Cohort studies that assessed the relationship between sleep duration at night and central obesity measures or body composition indices in adults were included. The quality of studies was assessed using the Newcastle-Ottawa scale. Random-effects meta-analysis was conducted on studies that reported risk ratio (RR) and 95% confidence intervals (CIs).
Eighteen studies were eligible to be included. Eleven out of the 18 studies were not included in the analysis as 10 studies did not report RR, and in one study, the definition of short and normal sleep duration was different from others. The results of the meta-analysis indicated that short sleep duration was significantly associated with abdominal obesity (RR = 1.08; 95% CI: 1.04-1.12; = 49.1%, n = 7), but long sleep duration was not (RR = 1.02; 95% CI: 0.83-1.24; = 98.2%, n = 6).
Short sleep duration was associated with a slightly higher risk of central obesity, while long sleep duration was not.
睡眠时间与肥胖之间的关系一直是众多研究的焦点。本项对前瞻性队列研究的系统评价和荟萃分析旨在评估睡眠时间、腹型肥胖和身体成分之间的关系。
检索了截至2024年2月的PubMed、Scopus和Web of Science数据库。纳入评估成年人夜间睡眠时间与中心性肥胖指标或身体成分指数之间关系的队列研究。使用纽卡斯尔-渥太华量表评估研究质量。对报告风险比（RR）和95%置信区间（CI）的研究进行随机效应荟萃分析。
18项研究符合纳入标准。18项研究中有11项未纳入分析，其中10项未报告RR，1项研究中短睡眠时长和正常睡眠时长的定义与其他研究不同。荟萃分析结果表明，短睡眠时间与腹型肥胖显著相关（RR = 1.08；95% CI：1.04 - 1.12；I² = 49.1%，n = 7），而长睡眠时间则不然（RR = 1.02；95% CI：0.83 - 1.24；I² = 98.2%，n = 6）。
短睡眠时间与中心性肥胖风险略高相关，而长睡眠时间则不然。
