Association of maternal prenatal depression and anxiety with toddler sleep: the China-Anhui Birth Cohort study.

Maternal prenatal depression is associated with child sleep. We investigated whether maternal depression comorbid with anxiety worsens toddler's sleep problems in a prospective cohort study. A total of 1583 mother-infant pairs from the China-Anhui Birth Cohort study were examined. The participants completed the Center for Epidemiologic Studies Depression Scale (CES-D) and Self-Rating Anxiety Scale (SAS) at 30–34 weeks of gestation, and the Edinburgh Postnatal Depression Scale (EPDS) at 3-month postpartum. Toddler's sleep was assessed by the Brief Infant Sleep Questionnaire (BISQ) at 30 months old. Logistic regression models were used to investigate the associations between prenatal depression and anxiety and toddler's sleep, while adjusting for maternal gestational age, education, family income, alcohol use, premature birth, fetal growth restriction, mode of delivery, postnatal depression, and 3-month breastfeeding. In total, 9.0% of participants reported prenatal depression comorbid with anxiety symptoms, and the prevalence of depression, anxiety was 6.7% and 7.3%, respectively. Compared with mothers without depression and anxiety, maternal depression combined with anxiety were significantly associated with shorter total sleep duration (11.16 ± 1.06 h), longer settling time (29.25 ± 23.57 min), and higher risk of toddlers' sleep problems assessed by BISQ (OR = 2.09, 95% CI: 1.22–3.57) or parental report (OR = 1.84, 95% CI: 1.22–2.77). However, there was no significant association between maternal postnatal depression and toddler sleep behaviors. Maternal prenatal depression comorbid with anxiety significantly associated with poorer toddler's sleep. Strategies to regulate prenatal mood status should be considered during prenatal health care to improve children's sleep development. [ABSTRACT FROM AUTHOR]
