Childhood maltreatment, parenting style and anxiety in Chinese youths: A case-control study.

Although evidence in supporting the associations between childhood maltreatment (CM), parenting style and anxiety in children and adolescents exists, few high-quality analytical epidemiological studies which focusing on clinically diagnosed anxiety disorders (AD) had been published. The aim of this study was to further corroborate the associations between CM, parenting style, and AD in a large representative sample of Chinese children and adolescents. Study subjects were derived from the Mental Health Survey for Children and Adolescents in Yunnan (MHSCAY), a population-based cross-sectional program. Individually matched case-control study design was adopted. Univariate and multivariate conditional binary logistic regression models were used to estimate the associations between CM, parenting style and AD. Dose-response trends were estimated using the Cochran-Armitage Chi-square test. A series of stratified analyses were conducted to explore effect modification on exposure-outcome association by some important features. Totally we screened out 202 cases and 404 matched controls, with an age mean of 14.43 years. Conditional logistic regression models revealed that EA and a higher level of parental over-protection were significantly associated with increased risk of AD, with adjusted ORs of 3.39 (95 % CI: 2.07–5.56) and 1.93 (95 % CI: 1.28–2.90). Stratified analysis identified noticeable effect modification by sex, age, and whether the only child in the family. Major findings of this study suggested that children and adolescents who had experienced EA or raised up by over-protective parents are at increased risk of AD. Targeted intervention measures should be developed and implemented for these high-risk youths. [ABSTRACT FROM AUTHOR]
