Association between maternal parenting stress and the trajectory of emotional and behavioral problems in preschool chil-dren
Objective To investige the association between maternal parenting stress and the trajectory of emotional and behav-ioral problems(EBPs)in preschool children,so as to provide a basis for promoting mental health of preschool children.Methods Using a stratified cluster random sampling and convenience sampling methods,a baseline survey was conducted in June 2021 among middle-class children at 36 kindergartens and their mothers,in three cities(Fuyang,Wuhu and Lu'an)in Anhui Province.The first follow-up survey was conducted in December 2021,then the follow-up survey was every 6 months for a total of three times,thus yielding 2 160 valid questionnaires.Latent class growth analysis(LCGA)was used to analyze the trajectory of preschool children's EBPs,and the association between maternal parenting stress and the development trajectory of preschool children's EBPs was ana-lyzed with multiple Logistic regression models.Results The developmental trajectories of EBPs among preschool children were classified into three groups:low-risk group(79.6%),increasing risk group(2.3%)and moderate-risk group(18.1%).After con-trolling for relevant confounding factors,such as gender,children's daily video time,mothers'education,mothers'emotional symp-toms(depression,stress,anxiety),family structure,with the low-risk group serving as the reference,maternal parenting stress was associated with elevated risk in both the moderate-risk and increasing risk groups of EBPs in preschool children[OR(95%CI)=1.06(1.05-1.06),1.03(1.02-1.05),P<0.05].Conclusions There is a group heterogeneity in EBPs among preschool children.Increased maternal parenting stress is a risk factor for the EBPs among preschool children.Providing targeted measures to alleviate maternal parenting stress is an important way to promote the healthy development of preschool children.
