Abstract

BACKGROUND

No studies have assessed the association between sleep duration and obesity in Chinese ethnic minorities. Whether the relationship between sleep duration and obesity is different between Chinese Han people and Chinese ethnic minorities remains unclear. The study aimed to explore the relationship between sleep duration and obesity among Chinese Han people and Chinese ethnic minorities.

METHODS

We applied data from the Guizhou Population Health Cohort Study (GPHCS), which 9,280 participants were recruited in the baseline survey from 2010 to 2012, and 8,163 completed the follow-up survey from 2016 to 2020. A total of 5,096 participants (3,188 Han Chinese and 1,908 ethnic minorities) were included in the ultimate analysis. Information on sleep duration (total 24-hour sleep time), body mass index (BMI), and waist circumference (WC) was collected at the baseline and follow-up survey, respectively. Cross-lagged panel analyses were conducted to explore the temporal relationship between sleep duration and obesity for Han people and ethnic minorities.

RESULTS

For Han people, the results from cross-lagged panel analyses indicated that baseline sleep duration was significantly associated with follow-up BMI (β = -0.041, 95% CI: -0.072 ~ -0.009) and follow-up WC (β = -0.070, 95%CI: -0.103 ~ -0.038), but baseline BMI (β = -0.016, 95% CI: -0.050 ~ 0.018) and baseline WC (β = -0.019, 95% CI: -0.053 ~ 0.016) were not associated with follow-up sleep duration. In addition, the relationship between baseline sleep duration and follow-up BMI was gender-specific and significant only in the Han people female (β = -0.047, 95% CI: -0.090 ~ -0.003) but not in the Han people male (β = -0.029, 95% CI: -0.075 ~ 0.016). For ethnic minorities, the results indicated that there was no relationship between sleep duration and obesity at all, either from sleep duration to obesity (β = 0.028, 95%CI: -0.012 ~ 0.068; β = 0.020, 95%CI: -0.022 ~ 0.062), or from obesity to sleep duration (β = -0.022, 95%CI: -0.067 ~ 0.022; β = -0.042, 95%CI: -0.087 ~ 0.003).

CONCLUSION

The relationship pattern between sleep duration and obesity across Han people and ethnic minorities is different. Future sleep-aimed overweight and obesity intervention should be conducted according to population characteristics.

摘要

背景

尚未有研究评估中国少数民族人群的睡眠时长与肥胖之间的关联。汉族人与中国少数民族人群之间睡眠时长与肥胖的关系是否存在差异尚不清楚。本研究旨在探索汉族人和中国少数民族人群的睡眠时长与肥胖之间的关系。

方法

我们应用了来自贵州人群健康队列研究（GPHCS）的数据。该研究于 2010 年至 2012 年进行了基线调查，共招募了 9280 名参与者，2016 年至 2020 年进行了随访调查，共 8163 名参与者完成了随访。最终分析纳入了 5096 名参与者（3188 名汉族人和 1908 名少数民族人）。在基线和随访调查中分别收集了睡眠时长（总 24 小时睡眠时间）、体重指数（BMI）和腰围（WC）信息。对汉族人和少数民族人群进行了交叉滞后面板分析，以探讨睡眠时长与肥胖之间的时间关系。

结果

对于汉族人，交叉滞后面板分析的结果表明，基线睡眠时长与随访 BMI（β=-0.041，95%CI：-0.072~~-0.009）和随访 WC（β=-0.070，95%CI：-0.103~~-0.038）显著相关，但基线 BMI（β=-0.016，95%CI：-0.050~~0.018）和基线 WC（β=-0.019，95%CI：-0.053~~0.016）与随访睡眠时长无关。此外，基线睡眠时长与随访 BMI 之间的关系存在性别特异性，仅在汉族女性中显著（β=-0.047，95%CI：-0.090~~-0.003），而在汉族男性中不显著（β=-0.029，95%CI：-0.075~~0.016）。对于少数民族人群，结果表明，睡眠时长与肥胖之间没有任何关系，无论是从睡眠时长到肥胖（β=0.028，95%CI：-0.012~~0.068；β=0.020，95%CI：-0.022~~0.062），还是从肥胖到睡眠时长（β=-0.022，95%CI：-0.067~~0.022；β=-0.042，95%CI：-0.087~~0.003）。
