摘要:
目的 本研究旨在探索海南省中老年人群BMI与睡眠时长和睡眠质量的关系,为超重肥胖防控提供参考依据。 方法 对2018年海南省18个市县的体检队列人群中5 169名调查对象进行体格检查和问卷调查。调查对象为本地居住时间≥5年,年龄35~75岁,无严重肢体残疾或精神疾病的常住人口。对BMI的影响因素进行描述性分析和单因素分析,应用有序Logistic回归分析模型分析BMI与睡眠时长和睡眠质量的关系。 结果 不同BMI调查对象在性别、教育程度、家庭年收入、年龄、吸烟、饮茶、午睡、睡眠质量、睡眠时长方面差异均有统计学意义(均有P < 0.05)。有序Logistic回归分析模型进一步分析结果显示,长枕组、睡眠质量较差和很差均为BMI水平增加的危险因素(均有P < 0.05);长枕组“BMI高”的OR值为规范枕组的1.336倍(95% CI:1.094~1.632);睡眠质量较差者与很差者“BMI高”的OR值分别为睡眠质量很好者的1.294倍(95% CI:1.082~1.548)和1.948倍(95% CI:1.131~3.357)。 结论 海南省中老年人睡眠时间延长、睡眠质量差都会增加超重肥胖的风险。 Abstract:Objective To explore the correlation of BMI and sleep duration or sleep quality in middle-aged and elderly population in Hainan, and to provide reference for prevention and control of overweight and obesity. Methods Physical examination and questionnaire survey were conducted on 5 169 physical examination cohort population in 18 Cities and Counties of Hainan Province in 2018. All participants were permanent residents who had been living in Hainan for more than 5 years, aged 35-75 years, and without severe physical disability or mental illness. The influencing factors of BMI were analyzed by descriptive and univariate analysis. The correlations of BMI and sleep duration or sleep quality were analyzed by ordered Logistic regression model. Results There were significant differences in gender, education, income level, age, smoking, tea drinking, noon-nap, sleep quality and sleep duration among different BMI groups (all P < 0.05).The further ordered Logistic regression analysis results showed that longer sleep duration, poor and very poor sleep quality were risk factors of higher BMI level (all P < 0.05). The risk of higher BMI in longer sleep duration was 1.336 times higher than normal sleep duration(95% CI: 1.094-1.632), and the risks of poor and very poor sleep quality groups were respectively 1.294 times higher(95% CI: 1.082-1.548)and 1.948 times higher (95% CI: 1.131-3.357)than good sleep quality group. Conclusion Longer sleep hours and poor sleep quality can increase the risk of overweight and obesity in middle-aged and elderly population in Hainan. -
