Investigations have found maternal adverse childhood experiences (ACEs) cause an intergenerational danger to their children's health. However, no study has investigated the effects of maternal ACEs on behavioral problems of preschool children in China and gender differences on these effects. This paper aims to investigate the role of maternal ACEs on behavioral problems of preschool children in China and explore gender differences as related to these behavioral problems. Stratified cluster sampling method was used to select 7318 preschool children from 12 districts in Hefei city, China. A questionnaire survey was conducted to collect information on maternal exposure to ACEs and Conners' Parent Rating Scales. Logistic regression was used to analyze the relationship between maternal ACEs and children's behavioral problems. The prevalence of behavioral problems in preschool children was 16.0%, while it was higher among girls (18.4%) than boys (13.92%) (χ2 = 27.979, p < 0.001). The rate of behavioral problems in children in the group of mothers with ACEs was higher than those without ACEs (all p < 0.05). Maternal ACEs were associated with increased risk of the behavior problems in preschool children (adjusted OR 2.91, 95% CI 2.45–3.45), and no gender difference (in girls 3.01, 2.38–3.81, in boys 2.79, 2.17–3.58, respectively) was found. Maternal ACEs were associated with increased risk of each type of the behavioral problems of preschool children, except that maternal emotional neglect was not associated with psycho-physical problems, impulse-activities, and anxiety. The only gender differences found were higher conduct problems related to maternal emotional abuse and ACEs and higher anxiety related to maternal physical abuse and community violence in girls compared with boys. Mothers exposured to ACEs are more likely to have children with behavioral health problems in preschool period. Further research is needed to explore the mechanisms by which maternal ACEs influence children's behavioral problems. [ABSTRACT FROM AUTHOR]

Aim: Left-behind children (LBC) now account for more than 1 in 5 Chinese children, and they often suffer from behavioural problems when their parents leave their rural homes to seek work in urban areas. The primary aim of this meta-analysis was to compare the incidence rates and factor scores of behavioural problems in LBC, who now account for more than one-fifth of Chinese children, and non-LBC.Methods: This systematic review and meta-analysis explored the children's characteristic behavioural problems using the Achenbach Child Behaviour Check List. A subgroup analysis was conducted to compare the different behavioural problems of LBC with different characteristics. The meta-analysis assessed 1405 papers and analysed 13 papers from 2007 to 2015, covering 10 264 LBC and 8909 non-LBC from 2 to 19 years of age.Results: The incidence rates of behavioural problems were higher in LBC than non-LBC. The highest risks were noted in boys aged between 6 and 11 years of age, who were more likely to be withdrawn and be affected by somatic complaints, schizophreniform disorder, compulsive behaviour and depression.Conclusion: Interventions and policies are urgently needed to tackle behavioural issues among LBC, especially high-risk males aged 6-11 years.

BJOG 2011;118:42-48. To prospectively examine the association between mode of delivery and childhood psychopathology. Retrospective cohort study. Eighteen counties and three cities in China. A total of 4190 preschool children whose mothers were registered in a perinatal surveillance programme were assessed with the Child Behaviour Checklist (CBCL), an instrument to assess child emotional (internalising) and behavioural (externalising) problems. Differences in CBCL problem scores were analysed both quantitatively and categorically among children born by caesarean delivery on maternal request (CDMR), assisted vaginal delivery (AVD), and spontaneous vaginal delivery (SVD). The CBCL total, externalising, and internalising scores. There were significant differences in the mean scores of total (20.9, 23.0, and 25.0), externalising (7.6, 8.4, and 9.1), and internalising (4.7, 5.2, and 5.6) problems among children born by CDMR, SVD, and AVD, after adjusting for potential confounding factors ( P = 0.007, 0.014, and 0.031). Children born by AVD were more likely than those born by SVD to have total (OR 1.43; 95% CI 1.10-1.86), externalising (OR 1.46; 95% CI 1.11-1.92), and internalising (OR 1.41; 95% CI 1.08-1.84) scores in the highest quartile, whereas children born by CDMR were less likely to have externalising scores in the highest quartile (OR 0.64; 95% CI 0.42-0.97). Furthermore, there were significant increasing linear trends on all problem scores, and in the odds of being in the highest quartile, from children born by CDMR to those born by SVD and AVD. The likelihood of childhood psychopathological problems may be the lowest in children born by CDMR, followed by those born by SVD, whereas the highest probability was observed in those born by AVD.

Background: Sleep plays a critical role in normal development and the effects of culture upon sleep are especially important in young children. The purpose of the present paper was to determine the sleep times and the prevalence of sleep problems and co-sleeping in children from Shanghai. Methods: A cross-sectional design incorporating parental self-report was used to investigate the sleep-related habits of 1129 children, 1–23 months of age, randomly selected from the five districts of Shanghai, China. Results: The total sleep time (TST) of Chinese young children was less than that reported in Western populations, and the prevalence of sleep problems (65.97%) was higher than that for Western children. The sleep problems of children were significantly related to perinatal factors and certain behavior problems. The rate of bed sharing did not differ between boys and girls but significantly increased with age from 44.07% in 1-month-olds to 71.51% in 23-month-olds. Conclusions: Sleep problems that cross cultures result from a variety of behavioral and health problems. Nevertheless, it is speculated that reduced TST in Chinese children may be related to factors unique to China, such as co-sleeping and child-rearing practices. [ABSTRACT FROM AUTHOR]

• The gender disparities in DCM vary among different maltreatment subtypes. • DCM's negative effect was more severe for girls than for boys. • Gender heterogeneity is less evident than gender homogeneity in the risk factors. Currently, gender disparities in domestic child maltreatment (DCM) have become an important and highly controversial issue worldwide. This study aims to provide panoramic evidence from China on this issue. Data were derived from a survey of 4,308 children (M age = 12.13, 48.7% were boys) conducted in seven provinces in rural China from June to December 2019. This study used multistage cluster sampling to select respondents, and modified versions of the JVQ Scale and the DSM-5 Scale (11–17 years old) were adopted. This study reached three significant conclusions. First, the gender disparities in DCM vary among different maltreatment subtypes. Compared with girls, boys are more likely to experience physical abuse. A higher prevalence of neglect is observed among girls than among boys. Second, although DCM significantly increased the likelihood of posttraumatic depression for all children, its negative effect was more severe for girls than for boys. Third, gender heterogeneity is less evident than gender homogeneity in the risk factors for DCM. In rural China, children's problematic behaviours, family structure, parents' experiences of childhood violence and family relationships are common predictors of maltreatment for all children. This paper highlights gender differences in the risk of DCM among children in rural China, reveals the Confucian culture behind DCM and gender, and provides Chinese evidence for building an international dialogue.
