[The relationship between maternal emotional symptoms during pregnancy and emotional and behavioral problems in preschool children: a birth cohort study].

OBJECTIVE: To investigate the related influencing factors of preschool children's emotional and behavioral problems in early life and explore the associations between the symptoms of depression or anxiety during pregnancy and emotional and behavioral problems in preschool children.
METHODS: Based on the Ma'anshan Birth Cohort Study of the China-Anhui Birth Cohort Study (C-ABCS), women were recruited at their first clinical visit between October 2008 and October 2010 in four municipal medical and health institutions of Ma'anshan City, a total of 5 084 pregnant women and 4 669 singletons live births were included in the birth cohort. Women completed measures of depressive (Self-Rating Anxiety scale) and anxious (Center for Epidemiologic Studies Depression) symptoms in pregnancy. By the age of 3-6 follow-up, 3 653 children were followed with completed information between April 2014 and April 2015, strengths and difficulties questionnaires were used to assessed offspring emotional and behavioral problems. Logistics regression was used to investigate the relationship between the symptoms of depression or anxiety during pregnancy and emotional and behavioral problems in preschool children.
RESULTS: The detected rates of emotional symptoms, conduct problems, hyperactivity and peer problems in preschool children were 6.3% (229/3 653), 7.5% (274/3 653), 7.6% (278/3 653) and 2.8% (103/3 653), while 7.6% (277/3 653) for total difficulties, 10.9%(398/3 653) for prosocial behavior and 27.4%(981/3 557) for impact respectively. Prevalence of anxiety and depression in the first trimester was 2.7%(100/3 653) and 4.7%(171/3 653) respectively, and in the second trimester was 2.0%(66/3 375) and 3.6%(122/3 375) respectively. After we controlled the confoundings of gestation age, place of residence, family income, maternal education, paternal education, premature birth and folic acid supplement before pregnancy, multinomial logistic regression analysis showed that the risk of children's emotional symptoms in maternal anxiety in both first-trimester and second-trimester group was higher than the group of no depression and anxiety symptoms, and OR(95%CI) was 5.90(2.00-17.48). Compared with whose mother no depression in both first-trimester and second-trimester, the risk of children's emotional symptoms in maternal depression in both first-trimester and second-trimester group was higher, and OR(95% CI) was 3.07 (1.30-7.28). And the risk of children's total difficulties of maternal anxiety in second-trimester was 2.27 (95%CI: 1.10-4.71) times of no anxiety in second-trimester. While the risk of children's total difficulties of maternal depression in second-trimester was 2.20 (95%CI: 1.24-3.93) times of no depression in second-trimester. Maternal emotional symptoms were not significant associations with conduct problems, hyperactivity, peer problems and prosocial behaviors (P> 0.05).
CONCLUSION: There was a negative impact of maternal anxiety and depression symptoms during pregnancy on emotional and behavioral problems in preschool children. These findings highlight the need for additional clinical and research attention to both maternal depression and anxiety in pregnancy, which may be helpful to reduce the incidence of children's emotional and behavioral problems and act as an important measure in prevention.
