Study of the determinants of sexual awareness and behaviors, and risk factors for delinquent sexual behaviors among adolescents in Japan

本研究的目的是描述青少年性意识和性行为的实际状况，以及这种意识和行为的决定因素，并调查性犯罪和意外怀孕的危险因素。在本研究中，我们收集并分析了定量和定性数据。首先，在大学生中进行了一项关于青春期性行为的匿名自述问卷调查。被调查学生共4225人，女31.5%，女68.5%，平均年龄20.3岁。约60%的受访者报告有过性行为，其中男性（17.7岁）首次发生性行为的年龄明显早于女性（18.2岁）。大约4.1%的受访者报告说他们目前有多个性伴侣，这些人被认为是性高危人群。尽管女性报告使用避孕药具的频率高于男性，但在4.7%的怀孕妇女中，有92.3%的人选择人工流产。我们也调查了人格因素和家庭教养作为性行为的决定因素之间的关系。以性行为为因变量，性情与性格量表（TCI）和亲代结合量表（PBI）为自变量，进行一系列回归分析。结果表明，TCI项目对性行为的影响强于PBI项目。换句话说，这项研究得出了一个新的结论，即性行为与气质的关系比与PBI的关系更大。我们还通过互联网调查了性意识。在回应的青少年中，选取415名女性（48.7%,51.3%）进行分析。调查结果显示，有过性行为的占32.7%。男性第一次发生性行为的平均年龄为14.3岁，女性为14.7岁。6%的人属于性行为高危人群，因为他们报告有不良性行为的经历。研究表明，大众传媒和同龄人之间的人际关系对儿童性行为的影响大于其所处的环境。此外，在研究的第二部分，我们对从性行业工作者或有过不良性行为的女性访谈中获得的定性数据进行了分析。结果表明，个人因素作为这些妇女的性行为和性意识的决定因素发挥了非常重要的作用，她们与异性成员的关系的影响以及负责抚养她们的人对她们的关心程度也以一种复杂而相互关联的方式参与其中。少

The purpose of this study was to describe the actual status of sexual awareness and sexual behavior in adolescence, along with the determinants of that awareness and behavior, and to investigate the risk factors for sexual delinquency and unwanted pregnancy.We gathered and analyzed both quantitative and qualitative data in this study. First, an anonymous self-report questionnaire survey regarding sex during adolescence was conducted among university students. A total of 4,225 students were surveyed female 31.5%, female 68.5%, mean age 20.3 years). About 60% of the respondents reported having experienced sexual intercoursei of these, the age when sexual intercourse first took place was significantly earlier in males (17.7 years) than females (18.2 years). Approximately 4.1% of the respondents reported that they presently had multiple sexual partners, and these were considered to comprise the sexual high-risk group. Although females reported using contraceptives more frequently than male … More s, 92.3% of the 4.7% of the women who had experienced pregnancy chose to have artificial abortions. We also investigated the relation between personality factors and family upbringing as determinants of sexual behaviors. A series of regression analyses were performed in which sexual behaviors were used as the dependent variables and Temperament and Character Inventory (TCI) and Parental Bonding Instrument (PBI) were the independent variables. The results indicated that TCI items had a stronger influence on sexual behaviors than PBI. In other words this study reached a new conclusion that sexual behaviors were more correlated with temperament than with PBI.We also investigated sexual awareness via the Internet. Of the teenagers who responded, 415 female 48.7%, female 51.3%) were selected and subjected to analysis. The results indicated that 32.7% of them had experienced sexual interoourse. The average age when sexual intercourse first took place was 14.3 years for males, and 14.7 years for females. Six percent of the total belonged to the sexual high-risk group because they roported experiences of delinquent sexual behavior. It was suggested that mass media and personal relations among the peer group had a groater influence on sexual behavior than the environment the child was raised in.Furthermore, in the second part of the study we carried out an analysis of qualitative data obtained from interviews with women who were sex-industry workers or who had experienced delinquent sexual behaviors. The results indicated that individual factors played very strong roles as determinants of sexual behavior and awareness among these women, and that the influence of their relationships with members of the opposite sex as well as the degree of concern shown by those responsible for their upbringing were also involved in a complex and interrelated manner.
