Abstract

Objectives

To examine the association of sleep duration and timing with BMI among adults. Also, to identify obesogenic and unhealthy behaviors (e.g.diet/sleep quality, physical activity, screen time, smoking) associated with short sleep duration and late bedtime.

Participants

Participants (n=755) were part of exploratory, population-based research, with data collection in a virtual environment.

Methods

For purposes of characterizing the population we considered short sleepers<7h/night, and the population bedtime median was used to stratify participants into early and late sleepers (before and after 23:08). Student's t-test and chi-square test were performed to assess differences in characteristics between groups. Linear regression analyses were conducted to determine the association of sleep duration, bedtime, and wake-up time with BMI. Quantile regression was estimated for the 25th, 50th, and 75th quantiles to identify the distributional correlations between BMI and sleep variables. Restricted cubic splines were also used to study the shape of the association between sleep-BMI. Analyses were adjusted for potential confounding variables.

Results

BMI decreased by 0.40Kg/m2 for each additional hour of sleep duration [95%CI=-0.68,-0.12,p=0.005] and increased by 0.37 kg/m2 for each additional hour of bedtime [95%CI=0.12,0.61,p=0.003]. The association between bedtime and BMI remained even after adjustment for sleep duration. These effects were higher and stronger with higher BMI values (p75th). Wake-up time did not show statistically significant associations.

Conclusions

Because we found that beyond sleep duration, bedtime was significantly associated with BMI, our data reflect the pertinence of assessing sleep timing patterns in disentangling sleep-obesity association. Insights into the characteristics, obesogenic and unhealthy behaviors related to short and late sleep may support specific strategies to prevent and treat excess body adiposity and other negative health outcomes.

睡眠时间之外:巴西成年人的睡眠时间与身体质量指数有关
目的研究成年人睡眠时间和时间与BMI的关系。此外,识别与睡眠时间短和就寝时间晚有关的肥胖和不健康行为(如饮食/睡眠质量、体育活动、屏幕时间、吸烟)。参与者参与者(n=755)是探索性的、基于人群的研究的一部分,在虚拟环境中收集数据。方法为了表征人群的特征,我们认为短睡眠者<;7小时/晚,使用人群就寝时间中位数将参与者分为早睡者和晚睡者(23:08之前和之后)。采用学生t检验和卡方检验来评估各组之间特征的差异。进行线性回归分析,以确定睡眠时间、就寝时间和起床时间与BMI的关系。对第25、第50和第75分位数进行了分位数回归估计,以确定BMI和睡眠变量之间的分布相关性。限制性三次样条曲线也被用于研究睡眠BMI之间的关联形状。针对潜在的混杂变量对分析进行了调整。结果BMI每增加一小时下降0.40Kg/m2[95%CI=-0.68,-0.12,p=0.005],每增加一个小时增加0.37kg/m2[95%CI=0.12,0.61,p=0.003]。BMI值越高,这些影响越大(p75th)。起床时间没有显示出统计学上显著的相关性。结论由于我们发现,在睡眠时间之外,就寝时间与BMI显著相关,我们的数据反映了评估睡眠时间模式在解开睡眠-肥胖关系中的相关性。深入了解与睡眠时间短和晚有关的特征、肥胖和不健康行为,可能会支持预防和治疗过度肥胖和其他负面健康结果的特定策略。
