To review the evidence on the relationship between daytime napping and obesity.
There is concern that napping may be harmful to metabolic health. Prospective studies have shown long time daytime napping (> 1 h) is associated with increased diabetes risk which may be partly associated with obesity. Evidence from numerous cross-sectional studies and meta-analyses of cross-sectional studies have shown that long time napping (> 1 h) but not short time napping is associated with increased risk of obesity, and this is seen worldwide. Inference regarding the nature of association from cross-sectional studies is limited; it is suggested the association is bidirectional. Prospective studies on the association between daytime napping and obesity are few and results unclear. Large longitudinal studies integrating daytime napping duration and night-time sleep behaviour and detailed information on lifestyle influences is needed to help elucidate further the associations of long time napping with obesity.
回顾关于日间小睡与肥胖之间关系的证据。
有人担心小睡可能对代谢健康有害。前瞻性研究表明，长时间日间小睡（>1小时）与糖尿病风险增加相关，这可能部分与肥胖有关。众多横断面研究及横断面研究的荟萃分析证据表明，长时间小睡（>1小时）而非短时间小睡与肥胖风险增加相关，且在全球范围内均有此现象。横断面研究对关联性质的推断有限；有人认为这种关联是双向的。关于日间小睡与肥胖之间关联的前瞻性研究较少，结果也不明确。需要进行大型纵向研究，综合日间小睡时长、夜间睡眠行为以及生活方式影响的详细信息，以进一步阐明长时间小睡与肥胖之间的关联。
