We examined the individual association between body mass index (BMI) and sleep quality among the very elderly. The present study analyzed data from survey that was conducted on all residents aged 90 years or more in a district, there were 2,311,709 inhabitants in 2005. Subjects were divided into four groups according to quartile of BMI (<16.6, 16.6-18.9, 18.9-21.1, >21.1 kg/m(2)) and according to classification criteria of underweight, normal weight, overweight, and obesity in BMI (<18.5, 18.5-23.0, 23.0-27.5, >27.5 kg/m(2)), respectively. Sleep quality was measured using The Pittsburgh Sleep Quality Index (PSQI). Sleep quality included quality classification and scores, sleep duration, sleep latency, and sleep efficiency. The subjects included in the statistical analysis were 216 men and 444 women. According to quartile of BMI or classification criteria of underweight, normal weight, overweight, and obesity in BMI, none of the differences in sleep quality scores, sleep latency, sleep duration, sleep efficiency percentage, and prevalence of poor sleep quality was significant among different BMI groups. The difference in BMI between subjects with good and poor sleep quality was non-significant. Unadjusted and adjusted multiple logistic regression showed that none of the BMI groups had a function of decreasing the risk for poor quality. Among longevity Chinese, there is no association between BMI and sleep quality.
我们研究了高龄老人体重指数（BMI）与睡眠质量之间的个体关联。本研究分析了对某地区所有90岁及以上居民进行的调查数据，2005年该地区有2311709名居民。根据BMI四分位数（<16.6、16.6 - 18.9、18.9 - 21.1、>21.1 kg/m²）以及BMI中体重过轻、正常体重、超重和肥胖的分类标准（<18.5、18.5 - 23.0、23.0 - 27.5、>27.5 kg/m²），将受试者分别分为四组。使用匹兹堡睡眠质量指数（PSQI）测量睡眠质量。睡眠质量包括质量分类和评分、睡眠时间、入睡潜伏期和睡眠效率。纳入统计分析的受试者有216名男性和444名女性。根据BMI四分位数或BMI中体重过轻、正常体重、超重和肥胖的分类标准，不同BMI组之间在睡眠质量评分、入睡潜伏期、睡眠时间、睡眠效率百分比和睡眠质量差的患病率方面均无显著差异。睡眠质量好与差的受试者之间BMI差异不显著。未调整和调整后的多元逻辑回归显示，BMI各组均无降低质量差风险的作用。在长寿的中国人中，BMI与睡眠质量之间无关联。
