Child sexual abuse: a study among 892 female students of a medical school / 中华儿科杂志

ABSTRACT

<p><b>OBJECTIVE</b>This study was designed to ascertain the prevalence of child sexual abuse (CSA) among female students of a medical school and to explore the impact of CSA on the mental health and health related risk behaviors of the victims being sexually abused and to provide useful reference for CSA prevention.</p><p><b>METHODS</b>A cross-sectional survey was carried out among 892 female students from a medical school by anonymous self-administered questionnaire during Oct. 2002. The questionnaire used for this study mainly included (1) general demographic information; (2) sexual experiences; (3) 12 forms of CSA. In this study, cases of CSA were defined as those who answered positively to one or more of the 12 questions relating to childhood sexual experiences (including non-physical contact CSA and physical contact CSA) occurring before age 16 with a person when a child did not want to. (4) Center for Epidemiologic Studies (CES)-Depression Scale; (5) Self Esteem Scale; (6) Risk Behaviors; (7) Health status' self-evaluation. Survey procedures were designed to protect students' privacy by allowing anonymous and voluntary participation. Students were seated separately, completed the self-administered questionnaire in their classrooms during a regular class period. Respondents were encouraged to participate in this survey, but given the sensitive nature of the subject, they could skip portion of the questionnaire if they were not comfortable with the questions. The completed questionnaires were sealed in envelopes by students themselves (the envelope was distributed with questionnaire at the same time), and then collected together. Data were analysed by using the Statistical Package for the Social Sciences software. Frequency, percentage, Chi-square test and t-test of statistics were used to analyze the CSA prevalence and explore the influence of CSA on mental health of students.</p><p><b>RESULTS</b>Among 892 female students, 25.6% reported having experienced CSA (any one of 12 forms non-physical contact and physical contact CSA) before the age of 16 years. The median age at first episode was 12 years. Comparing the rates of CSA of female students in different parents' education level, between one-child in a family and more than one-child in a family, among rural area, county and city, there were no significant differences. Compared to the students who had not experienced CSA, the students who had experienced CSA reported higher levels of depression (CES-D score 18.78 vs. 16.68, t = 2.81, P = 0.005), lower levels of health status self-evaluation (score 3.53 vs. 3.78, t = 2.94, P = 0.003); higher proportion of subjects who reported drinking alcohol and having ever smoked during the past 30 days (drinking 32.7% vs. 22.9%, chi(2) = 8.51, P = 0.004; smoking 8.8% vs. 4.4%, chi(2) = 6.17, P = 0.013); a higher percentage engaged in sexual intercourse (19.3% vs. 5.9%, chi(2) = 33.48, P = 0.000); ever seriously considered attempting suicide (23.7% vs. 15.4%, chi(2) = 8.09, P = 0.004), making a plan about how would attempt suicide (17.9% vs. 9.7%, chi(2) = 10.62, P = 0.001), being threatened or injured by someone with a weapon such as a knife, or club on school property (3.5% vs. 1.1%, chi(2) = 6.17, P = 0.013), being involved in physical fight (16.7% vs. 5.6%, chi(2) = 27.05, P = 0.000) during the 12 months preceding the survey.</p><p><b>CONCLUSIONS</b>The results further showed that the CSA of girls in our country is not uncommon, as reported before in our country and in the other countries and is associated with poor mental health and risky behaviors. The findings highlight the urgent need for the further research into CSA epidemiological characteristics, health services for the victims abused sexually, sexual abuse prevention programs in schools and the general community in China.</p>
