Research on neighborhood socioeconomic conditions and sleep and circadian health shows inconsistent findings. Small sample sizes and few sleep measures may have limited prior studies. In a large cohort, we examined the association between neighborhood deprivation and sleep and circadian health.
The Cancer Prevention Study-3 is a prospective cohort of US adults enrolled in 2006-2013. The Neighborhood Deprivation Index (NDI) was derived using principal components analysis of census tract--level American Community Survey data and was linked to participants' geocoded address at baseline. Participants (N = 180,379) self-reported their sleep duration, sleep midpoint, social jetlag, sleep quality, and chronotype on the 2015 or 2018 follow-up survey. Linear or logistic regression was used to estimate associations between NDI in quintiles and each outcome.
Compared with the least deprived neighborhoods, living in the most deprived neighborhoods was associated with a higher odds of short (<7 hours) and long (>9 hours) sleep duration (short: odds ratio [OR] = 1.23, 95% confidence interval [CI] 1.17-1.30; long: OR = 1.08, 95% CI 1.04-1.13). Neighborhood deprivation was also associated with a 4.84-minute later sleep midpoint (beta = 4.84, 95% CI 2.77-6.91), high (>120 minutes) social jetlag (OR = 1.38, 95% CI 1.30-1.48), poor sleep quality (OR = 1.04, 95% CI 1.00-1.09), and having an evening chronotype (OR = 1.07, 95% CI 1.03-1.11).
In this large study, neighborhood deprivation was associated with poor sleep and circadian health, particularly short and long sleep duration and high social jetlag. The neighborhood environment may be a useful target to improve sleep and circadian health and influence downstream health outcomes.
关于邻里社会经济状况与睡眠及昼夜节律健康的研究结果并不一致。样本量小和睡眠测量指标少可能限制了先前的研究。在一个大型队列中，我们研究了邻里贫困与睡眠及昼夜节律健康之间的关联。
癌症预防研究-3是一项针对2006年至2013年招募的美国成年人的前瞻性队列研究。邻里剥夺指数（NDI）是通过对普查区层面的美国社区调查数据进行主成分分析得出的，并与参与者基线时的地理编码地址相关联。在2015年或2018年的随访调查中，参与者（N = 180,379）自我报告了他们的睡眠时间、睡眠中点、社会时差、睡眠质量和昼夜节律类型。使用线性或逻辑回归来估计五分位数的NDI与每个结果之间的关联。
与最不贫困的邻里相比，生活在最贫困的邻里中，睡眠时间短（<7小时）和长（>9小时）的几率更高（短：比值比[OR] = 1.23，95%置信区间[CI] 1.17 - 1.30；长：OR = 1.08，95% CI 1.04 - 1.13）。邻里贫困还与睡眠中点延迟4.84分钟（β = 4.84，95% CI 2.77 - 6.91）、高（>120分钟）社会时差（OR = 1.38，95% CI 1.30 - 1.48）、睡眠质量差（OR = 1.04，95% CI 1.00 - 1.09）以及具有晚型昼夜节律（OR = 1.07，95% CI 1.03 - 1.11）相关。
在这项大型研究中，邻里贫困与睡眠及昼夜节律健康不佳相关，尤其是睡眠时间短和长以及高社会时差。邻里环境可能是改善睡眠及昼夜节律健康并影响下游健康结果的一个有用目标。
