Influence of growing experience on non-heterosexual orientation among male college students in Nanjing

目的 分析成长经历对在校男大学生自我认同为非异性性取向的影响.方法 于2015年10—11月,在南京市两所防艾试点高校内进行整群随机抽样,抽取了14个学院/系中96个班级内的所有男性学生,共2535名.采用结构性问卷对其进行调查,问卷内容包括基本情况、成长经历及金赛量表（该表用来判定调查对象自我性取向认同）3个部分.本研究共发放问卷2500份,收回有效问卷2332份,有效率为93.3%.采用χ2检验比较不同特征调查对象自我认同为非异性恋的差异;采用多因素logistic回归模型分析影响调查对象自我认同为非异性恋的因素.结果 2332名调查对象中,自我认同为非异性恋的比例为6.2%（144名）;其中大一、大二、大三和大四学生自我认同为非异性恋的比例分别为5.2%（63/1216）、6.9%（65/941）、11.7%（13/111）和4.7%（3/64）（χ2=9.06,P=0.029）.与小时父母关系非常好者相比,小时父母关系不好和一般的调查对象自我认同为非异性恋的OR（95%CI）值分别为3.3（1.7-6.5）和1.7（1.0-2.9）;与未遭遇过性侵犯经历者相比,有过该经历的调查对象自我认同为非异性恋的OR（95%CI）值为5.9（3.2-10.9）.结论 南京市在校大学生自我认同为非异性恋的比例较高,小时父母关系不好及遭遇过性侵犯的学生性取向发展需要加以关注.

Objective To analyze the influence of growing experience on non-heterosexual orientation among male college students. Methods From October to November in 2015, a total of 2535 male students from 96 classes in 14 colleges/departments were recruited from two colleges that participated in the experimental work of AIDS prevention by cluster random sampling method. A structured questionnaire was administered in this study, including general demographic information, growing experience and Kinsey scale （to evaluate sexual orientation）. Out of 2500 questionnaires distributed in this study, 2332 effective copies were withdrew, with the effective rate at 93.3%. Chi square test was used to analyze the differences of non-heterosexual orientation among the individuals with different social demographic characteristics. Multivariate logistic regression model was used to analyze the influencing factors of non-heterosexual orientation. Results Among the 2332 individuals, the proportion of self-reported non-heterosexual was 6.2%（144）.The proportions of male students who identify as non-heterosexual from freshman to junior year were 5.2% （63/1216）,6.9% （65/941）,11.7% （13/111） and 4.7% （3/64）, respectively （χ2=9.06,P=0.029）. Compared with the individuals of very good relationship with parents, those with bad relationship （OR=3.3, 95%CI： 1.7-6.5） and general relationship （OR=1.7, 95%CI： 1.0-2.9） with parents had a higher risk of non-heterosexual orientation, respectively. Those encountered sexual assault had a higher risk of non-heterosexual orientation than those without encountered sexual assault （OR=5.9, 95%CI： 3.2-10.9）. Conclusions This study reported a high proportion of self-reported non-heterosexual among college male students in Nanjing, and highlighted the importance of targeting students with poor parental relationships and who subjected to sexually abused.
