Objective: To explore the relationship of maternal adverse childhood experiences(ACEs) with mother child relationship, so as to provide reference for parent child relationship and child health promotion. Methods: In June 2021, children aged 3-6 years old of 36 kindergartens in three areas in Anhui Province were selected by stratified cluster sampling method, follow up data were collected in December 2021, and a total of 6 111 children were included in the study. Maternal ACEs and mother child relationship were respectively assessed using the Adverse Childhood Experiences International Questionnaire(ACEs-IQ)and the Child Parent Relationship Scale (CPRS). A multiple linear regression model was established to analyze the association of maternal ACEs and mother child relationship in preschool children. Results: History of maternal childhood sexual abuse, physical neglect and peer bullying were negatively associated with mother child intimacy ( r =-0.03, -0.03, -0.03, P <0.05). Maternal emotional abuse, physical abuse, sexual abuse, emotional neglect, physical neglect, peer bullying, community violence, and total family dysfunction were positively associated with mother child dependence and mother child conflict ( r =0.09, 0.08, 0.05, 0.14, 0.06, 0.11, 0.08, 0.04; 0.18, 0.17, 0.07, 0.20, 0.11, 0.16, 0.12, 0.10, P <0.01). There was no statistically significant between all types of maternal ACEs and mother child intimacy in boys( P >0.05). Mothers with a history of physical abuse, sexual abuse and peer bullying had a statistically significant relationship between mother child intimacy in girls( β =-0.17, -0.62, -0.19, P <0.05). All types of maternal ACEs were positive predictors of mother child conflict between boys and girls( β =0.37-1.96, P <0.05). There was statistical significance between maternal childhood sexual abuse and mother child dependence of boys( β =0.53, P <0.05), but no statistical significance between maternal childhood sexual abuse and mother child dependence of girls( P >0.05). All other types of maternal ACEs were positive predictors of mother child dependence( β =0.09-0.41, P <0.05). Conclusion Maternal ACEs are associated with poor mother child relationship among preschool children, and maternal ACEs should be actively followed, which is of great significance for improving the parent child relationship and promoting child healthy development.

Objective: To explore the relationship and gender difference between family rearing styles with emotional and behavior problems in preschool children aged 3-6 years, so as to provide reference for early prevention and intervention of children s emotional and behavior problems. Methods: Using the method of stratified cluster sampling, 9 647 children aged 3-6 years old from 36 kindergartens in Wuhu, Lu an and Fuyang of Anhui Province were selected in June 2021. Primary caregivers were investigated with self designed questionnaire, Strengths and Difficulties Questionnaire (parents version) and Parental Rearing Style Scale. Results: The detection rate of elevated SDQ total difficulty score was 6.5%, with boys (7.1%) higher than that of girls (5.8%). The detection rate of abnormal emotional behavior were significantly higher in children with high scores on doting, laissez faire, autocracy and inconsistency of family rearing style, compared with those in the low score group ( χ 2=210.32, 203.87, 102.70, 212.69, P <0.01 ), and the detection rate increased with the increase of score. However, the detection rate of abnormal emotional behavior in the high score group of democracy was significantly lower than that in the low score group ( χ 2=156.24, P <0.01), and the detection rate decreased with the increase of score. Logistic regression analysis showed that high level doting ( OR =4.31), laissez faire ( OR = 4.16), autocracy ( OR =3.36) and inconsistency ( OR =4.76) of family rearing style were associated with high risk of children s emotional behavior problems, while high level of democracy ( OR =0.34) in family rearing style was associated with low risk of emotional behavior problems. The comparison between boys and girls showed that the risk of emotional and behavioral problems in the indulgent rearing style of boys was significantly higher than that of girls ( OR =1.90, 2.13) ( P <0.05). Conclusion Family rearing styles are associated with emotional and behavioral problems among preschool children. Boys are sensitive to the negative impact of doting rearing style. Good rearing styles is beneficial to the prevention and control of children s emotional and behavioral problems.
