ABSTRACT

Objective To explore the relationship of family environment in childhood and adolescence and mental health in adulthood.Methods A total of 791 subjects aged ≥25 years were selected through the Chinese National Twin Registry (CNTR).The short-form of Family Environment Scale-Chinese Version (FES-CV) was used to evaluate the family environment during childhood and adolescence in three dimensions:relationship,system maintenance and personal growth.The mental health status in adulthood was assessed with the Chinese version of 6-item Kessler Psychological Distress Scale (K6).The generalized linear mixed model was used to examine their relationship.Results About 4.6％ of the subjects reported general or worse mental health status.Compared with the subjects with good mental status,statistical difference was observed only in parenting way among twins (living together or not).After adjusting the potential confounders,such as age,sex,zygosity,education and lifestyle (smoking,drinking and physical activity),good family relationship and system maintenance had a positive effect on mental health,with the OR (95％CI) of 0.66 (0.5 1-0.87) and 0.70 (0.50-0.98) respectively.Furthermore,parenting way did not modify the effect of family environment on mental health status in adulthood (interaction:P＞0.05).In each scale,scores of cohesion and organization were positively correlated with mental health,while the score of conflict was negatively correlated with the mental health.Conclusion Good family relationship and system maintenance in childhood and adolescence had a positive impact on mental health in adulthood.
