To investigate the associations of the sleep-eating interval with eating times and food consumption throughout the day in pregnant women. A longitudinal study with 100 pregnant women treated at the public health network in the city of Uberlândia, state of Minas Gerais (MG), Brazil, during the entire gestational period. The time intervals between waking up and the first eating episode and between the last eating episode and going to sleep (independent variables) were investigated. Outcome measures were meal and sleep times, as well as food consumption throughout the day. Food consumption closer to sleep at night is associated with higher total daily caloric intake in the first (β = -0.337, = 0.016) and second trimesters (Ts) of pregnancy (β = -0.240, = 0.023), and with longer sleep duration on weekdays ( < 0.05 for all three trimesters). We did not find associations between the wake-up to first eating episode interval and total calories ( > 0.05 for all three trimesters), but the longer this interval, the greater the percentage of calories at dinner (1T: β = 0.266, = 0.003; 2T: β = 0.269, = 0.045) and at the last meal (1T: β = 0.324, = 0.001; 2T: β = 0.231, = 0.033). Taking longer to eat the first meal after waking up is associated with higher caloric intake later in the day, while taking longer to sleep after eating the last meal is associated with higher total daily caloric intake and shorter sleep duration, especially in the beginning and middle of pregnancy.
研究孕妇睡眠-进食间隔与全天进食时间及食物摄入量之间的关联。
对巴西米纳斯吉拉斯州乌贝兰迪亚市公共卫生网络治疗的100名孕妇进行了一项纵向研究，研究贯穿整个孕期。研究了醒来至首次进食之间以及最后一次进食至入睡之间的时间间隔（自变量）。观察指标为进餐和睡眠时间以及全天的食物摄入量。
夜间进食时间越接近睡眠时间，与妊娠第一孕期（β = -0.337，P = 0.016）和第二孕期（β = -0.240，P = 0.023）的每日总热量摄入越高相关，且与工作日更长的睡眠时间相关（三个孕期均P < 0.05）。我们未发现醒来至首次进食间隔与总热量之间存在关联（三个孕期均P > 0.05），但该间隔越长，晚餐热量百分比越高（第一孕期：β = 0.266，P = 0.003；第二孕期：β = 0.269，P = 0.045）以及最后一餐热量百分比越高（第一孕期：β = 0.324，P = 0.001；第二孕期：β = 0.231，P = 0.033）。
醒来后吃第一餐花费时间越长，与当天晚些时候热量摄入越高相关，而吃完最后一餐至入睡花费时间越长，与每日总热量摄入越高及睡眠时间越短相关，尤其是在妊娠初期和中期。
