Introduction To determine the association of fruit and vegetable consumption with overall sleep duration among pregnant women. Methods Data from the 2011 and 2012 Behavioral Risk Factors Surveillance System (BRFSS) were used. All women (n = 2951) of childbearing age (18-44 years) who were pregnant and responded to all fruit and vegetable consumption and sleep duration questions were included. Covariates included age, race, education level, exercise, and marital status. Data were analyzed using linear and ordinal logistic regression. Results Total daily fruit and vegetable consumption was not associated with sleep duration among pregnant women, controlling for confounders [β = -0.03, (-0.07, 0.00)]. Orange and green vegetable consumption were both inversely associated with sleep duration [β = -0.19, (-0.38, -0.01) and β = -0.20, (-0.33, -0.08) respectively]. Ordinal logistic regression found that the odds of meeting or exceeding sleep time recommendations increased slightly with each unit increase in total fruit and vegetable consumption [OR = 1.05 (1.003, 1.092)] and for every unit increase in fruit consumption [OR = 1.12 (1.038, 1.208)]. Women who exercised within the past 30 days reported approximately 20 min of additional sleep compared to those who did not [β = 0.32 (0.16, 0.49)]. Age, employment status, and marital status were also independently associated with sleep duration. Discussion Sleep duration in pregnant women was associated with exercise and other demographic factors, but only mildly associated with fruit and vegetable consumption. Future research should investigate the effects of additional factors including sleep quality, gestational age, family status and other medications as potential confounders.
确定孕妇水果和蔬菜摄入量与总体睡眠时间之间的关联。方法：使用2011年和2012年行为危险因素监测系统（BRFSS）的数据。纳入所有年龄在18 - 44岁之间、怀孕且回答了所有水果和蔬菜摄入量及睡眠时间问题的育龄妇女（n = 2951）。协变量包括年龄、种族、教育水平、运动情况和婚姻状况。采用线性和有序逻辑回归分析数据。结果：在控制混杂因素后，孕妇每日水果和蔬菜的总摄入量与睡眠时间无关联[β = -0.03，（-0.07，0.00）]。橙色蔬菜和绿色蔬菜的摄入量均与睡眠时间呈负相关[分别为β = -0.19，（-0.38，-0.01）和β = -0.20，（-0.33，-0.08）]。有序逻辑回归发现，水果和蔬菜总摄入量每增加一个单位，达到或超过睡眠时间建议的几率略有增加[OR = 1.05（1.003，1.092）]，水果摄入量每增加一个单位，该几率也增加[OR = 1.12（1.038，1.208）]。与未运动的女性相比，过去30天内运动的女性报告睡眠时间多出约20分钟[β = 0.32（0.16，0.49）]。年龄、就业状况和婚姻状况也与睡眠时间独立相关。讨论：孕妇的睡眠时间与运动及其他人口统计学因素有关，但与水果和蔬菜摄入量仅有轻微关联。未来研究应调查包括睡眠质量、孕周、家庭状况和其他药物等其他因素作为潜在混杂因素的影响。
