AIMS
The effect of race/ethnicity on the risk of obesity associated with short or long sleep durations is largely unknown. This study assessed whether the sleep-obesity link differentially affects black and whites.
METHODS
Analysis was based on data obtained from 29,818 adult American respondents from the 2005 National Health Interview Survey, a cross-sectional household interview survey.
RESULTS
Multivariate-adjusted odds ratios for obesity associated with short sleep (≤6 h) among blacks and whites were 1.98 (95% CI: 1.69-2.30) and 1.20 (95% CI: 1.10-1.31), respectively, and with long sleep (≥9 h) for blacks and whites were 1.48 (95% CI: 1.14-1.93) and 0.77 (95% CI: 0.67-0.89), respectively (all p < 0.001).
CONCLUSION
Race/ethnicity may have significantly influenced the likelihood of reporting obesity associated with short and long sleep durations. Relative to white respondents, an excess of 78% of black respondents showed increased obesity odds associated with short sleep. Black long sleepers also showed increased odds for obesity, but white long sleepers may be at a reduced obesity risk.
目的
种族/族裔对与短睡眠或长睡眠时长相关的肥胖风险的影响在很大程度上尚不清楚。本研究评估了睡眠与肥胖之间的关联是否对黑人和白人有不同影响。
方法
分析基于从2005年全国健康访谈调查中获得的29,818名美国成年受访者的数据，这是一项横断面家庭访谈调查。
结果
黑人和白人中与短睡眠（≤6小时）相关的肥胖的多变量调整比值比分别为1.98（95%置信区间：1.69 - 2.30）和1.20（95%置信区间：1.10 - 1.31），与长睡眠（≥9小时）相关的肥胖的多变量调整比值比分别为1.48（95%置信区间：1.14 - 1.93）和0.77（95%置信区间：0.67 - 0.89）（所有p < 0.001）。
结论
种族/族裔可能显著影响了报告与短睡眠和长睡眠时长相关的肥胖的可能性。相对于白人受访者，超过78%的黑人受访者因短睡眠而肥胖几率增加。黑人长睡眠者的肥胖几率也增加，但白人长睡眠者的肥胖风险可能降低。
