睡眠时间短与多种不良儿童结局有关。我们在一个出生前队列的1226名参与者中检查了建筑环境与婴儿睡眠时间的关系。从住宅区出发，我们使用地理信息系统来确定都市性、人口密度以及与主要道路的距离。主要结果是母亲报告了她的婴儿在1岁时的平均每日睡眠时间。我们以五分位数为单位对都市性和人口密度进行排名，将到主要道路的距离分为8类，并使用线性回归方法对社会人口学特征、孕期吸烟、胎龄、胎儿发育和1岁时看电视进行了调整。在这个样本中，1岁时的平均(SD)睡眠时间为12.8(1.6)小时/天。在多变量调整分析中，居住在城市化程度最高五分之一的儿童每天睡眠−19.2分钟(95%可信区间：−37.0，−1.50)比生活在最低五分之一的儿童少。经多因素调整后，人口密度和距离主干道的距离与婴儿睡眠时间无关。我们的发现表明，生活在更多的城市环境中可能与婴儿睡眠减少有关。
Short sleep duration is associated with multiple adverse child outcomes. We examined associations of the built environment with infant sleep duration among 1226 participants in a pre-birth cohort. From residential addresses, we used a geographic information system to determine urbanicity, population density, and closeness to major roadways. The main outcome was mother’s report of her infant’s average daily sleep duration at 1 year of age. We ranked urbanicity and population density as quintiles, categorized distance to major roads into 8 categories, and used linear regression adjusted for socio-demographic characteristics, smoking during pregnancy, gestational age, fetal growth, and television viewing at 1 year. In this sample, mean (SD) sleep duration at age 1 year was 12.8 (1.6) hours/day. In multivariable adjusted analyses, children living in the highest quintile of urbanicity slept −19.2 minutes/day (95% CI: −37.0, −1.50) less than those living in the lowest quintile. Neither population density nor closeness to major roadways was associated with infant sleep duration after multivariable adjustment. Our findings suggest that living in more urban environments may be associated with reduced infant sleep.
