Objective To investigate underlying factors,exacerbating factors,clinical manifestations,and videotaping feasibility in Chinese childhood masturbation (CM) children and study behavioral implications of CM in children over 6 years of age. Methods 89 CM cases were collected by phone calls and a specially designed form for parents;Achenhach Child Behavior Checklist(CBCL)was used to assess behavioral implications of CM in 21 female cases over 6 years of age.SPSS 17.0 software was applied to analyze the results.Results 1)70.79% of CM were seen in children lying on the bed before falling asleep,and there were varying degrees similar to adult orgasm,67.21% of children over 3 years of age described the experience as being pleasant.2)The underlying factors/ exacerbating factors of CM were various,65.71% was lack of affective care from parents,such as less parents' time with child,lack of body touch/warmly affective contact from parents.46.07% of CM were induced by perineal irritation.3) 73.03% of parents did not agree with videotaping CM events of their children.4)the behavioral problems disclosed by CBCL in CM female cases over 6 years of age (24.38±14.32) were not significant different from control (20.76±15.3). Conclusion CM is similar to adult masturbation,and to some degree with adult orgasm.Lack of affective care from parents was probably the most outstanding among the underlying factors/exacerbating factors of CM.The implication of videotape for the diagnosis of CM is limited in China,as majority of parents do not accept.Behavioral problems in CM female children over 6 years of age are not prominent.
