AIDS-related knowledge among college freshmen and its influence on sexual attitudes and behaviors in Jiangsu Province

Objective To investigate the status of knowledge about acquired immune deficiency syndrome (AIDS) among college freshmen in Jiangsu Province, and to analyze the influences of AIDS-related knowledge on their sexual attitudes and behaviors. Methods A total of 8 633 freshmen from 20 colleges and universities in Jiangsu Province were enrolled by multi-stage stratified sampling. The questionnaire for young students about the eight items of AIDS basic knowledge were used to investigate the AIDS-related knowledge, sexual attitudes and behaviors. Multivariate Logistic regression model was used to analyze the influencing factors of the AIDS-related knowledge and to adjust the influences of AIDS-related knowledge on sexual attitudes and behaviors. Results The overall qualified rate of AIDS-related knowledge among college freshmen in Jiangsu Province was 87.6% and the qualified rate of 8 items were between 59.8% and 98.3%. The types of schools, nationality, mother’s education level and whether only child or not were identified as independent factors for qualified rate of AIDS-related knowledge ( P <0.05) . The awareness of AIDS-related knowledge had significant impacts on the sexual attitudes and behaviors of college freshmen. Students with insufficient knowledge were more likely to approve premarital sexual behaviors ( OR =1. 31，95% CI = 1.11- 1.63), willing to use condoms consistently ( OR = 1.67, 95% CI = 1.43-1.92) and to accept the HIV tests ( OR = 4.54, 95% CI = 3.13-6.52). Students with unqualified knowledge were more likely to have sexual behavior ( OR = 1. 89, 95%CI = 1.42-2.49), while those with sexual experiences and insufficient AIDS knowledge were more likely to use condoms consistently ( OR = 2.13, 95% CI = 1.22-3.78). Conclusion The education on AIDS-related knowledge for teenagers was helpful to construct correct sexual concepts and develop healthy sexual behaviors. However, the AIDS-related knowledge of college freshmen in Jiangsu Province is not sufficient and needed to improve. 【摘要】 目的 了解江苏籍大一新生艾滋病知识知晓情况及其对性态度和性行为的影响，为针对性开展青少年学生预防 艾滋病教育提供科学依据。 方法 多阶段分层随机抽取江苏省20所髙校的8 633名江苏籍大一新生，通过艾滋病知识 “国八条”问卷在线调査艾滋病知识知晓情况和性态度、性行为状况。采用多因素Logistic回归模型分析知识知晓情况的 影响因素，校正知识对性态度和性行为的影响。 结果 江苏籍大一新生艾滋病知识总体知晓率为87.6%，8个条目的知晓 率为59.8%~98.3%。学校类型、民族、母亲文化程度和是否独生子女是影响大一新生艾滋病知识知晓情况的独立因素（ P 值均<0.05)。艾滋病知识知晓情况对学生的性态度及性行为具有影响，知识知晓者比不知晓者更倾向于赞成婚前性行为 ( OR =1.31，95% CI = 1.11 ~ 1.63)，更愿意坚持使用安全套（ OR = 1.67,95% CI = 1.43 ~ 1.92)和接受艾滋病毒抗体检测（ OR = 4.54,95%CI =3.13~6.52);知识不知晓者已发生性行为比例更髙（ OR =1.89,95% CI = 1.42~2.49);发生过性行为的新生中 知识知晓者坚持使用安全套的比例更髙（ OR = 2.13,95% CI = 1.22~ 3.78)。 结论 江苏籍大一新生艾滋病知识知晓的比例 尚未达到国家规定的青年学生达90%的标准。艾滋病知识教育有助于青少年形成正确的性观念，养成健康的性行为。
