To identify the factors related to sleep duration in 3-month-old infants. From 2021 to 2023, we conducted a cross-sectional study in the city of Araraquara, Brazil, involving 140 mothers and their respective 3-month-old infants. Maternal socioeconomic, demographic, obstetric, and nutritional characteristics, as well as nutritional and morbidity characteristics of the respective infants, were evaluated. Sleep duration was determined by the Brief Infant Sleep Questionnaire (BISQ). Multivariate linear regression analysis was used to assess the associations of maternal, newborn, and infant factors with sleep duration at three months. The nighttime sleep duration of the infants was of 9 hours. There were negative associations between nighttime sleep duration and prone sleep position ( = 0.011), falling asleep between 8:30 pm and 11:00 pm ( = 0.032), falling asleep after 11:00 pm ( < 0.001), respiratory infection ( = 0.011), dermatitis ( = 0.002), and the presence of children under 9 years of age in the household ( = 0.013). In the present study, factors such as infant morbidity, the presence of other children in the household, and sleeping habits were associated with a decrease in sleep duration in 3-month-old infants. Therefore, we emphasize the importance of early diagnosis of morbidity in the first months of life and of promoting healthy habits such as regulating the time to go to sleep, providing an adequate sleep environment, and other practices that help improve the quality and duration of sleep.
确定3个月大婴儿睡眠时长的相关因素。2021年至2023年，我们在巴西阿拉拉夸拉市开展了一项横断面研究，涉及140名母亲及其各自3个月大的婴儿。评估了母亲的社会经济、人口统计学、产科和营养特征，以及各自婴儿的营养和发病特征。睡眠时长由简易婴儿睡眠问卷（BISQ）确定。采用多元线性回归分析评估母亲、新生儿和婴儿因素与3个月时睡眠时长的关联。婴儿的夜间睡眠时长为9小时。夜间睡眠时长与俯卧睡眠姿势（ = 0.011）、晚上8:30至11:00入睡（ = 0.032）、晚上11:00后入睡（ < 0.001）、呼吸道感染（ = 0.011）、皮炎（ = 0.002）以及家中有9岁以下儿童（ = 0.013）之间存在负相关。在本研究中，婴儿发病情况、家中有其他儿童以及睡眠习惯等因素与3个月大婴儿的睡眠时长减少有关。因此，我们强调在生命的头几个月对发病情况进行早期诊断以及促进健康习惯的重要性，如规范入睡时间、提供适宜的睡眠环境以及其他有助于改善睡眠质量和时长的做法。
