This study examined the masturbatory experiences and other sexual activities of young Korean males in military service. The actual status of masturbation and its relationship to sexual activity questionnaire. A total of 1,212 young males among military personnel in Korea were interviewed with sexuality questionnaires on masturbation, sexual intercourse and personal characteristics. We divided these subjects into four groups according to the age of initiation of masturbation and analyzed the relationship between masturbation and other sexual activities. The mean age of subjects was 22.03 +/- 1.22 (19-27) years. The percentage of men who reported ever having masturbated was 98.1% (1189/1212) and the average age of initiation of masturbation was 14.26 +/- 1.66 years. So we divided 1,212 males into four groups on the basis of the average age below and above one standard deviation. Overall, 67.7% (821/1212) had experienced sexual intercourse, and significantly, the earlier the initiation age of masturbation, the higher the coitus rate in each group (p < 0.05). About 21.5% of the men who were not virgins had experienced their first sexual intercourse with prostitutes. The mean age of first coitus, the incidence of sexually transmitted disease (STD) and the frequency of masturbation were closely linked to the initiation age of masturbation, respectively (p < 0.05). A masturbatory guilt feeling was seen in about 10.9% (132/1212) and there was no significant difference according to the types of religious worship (p = 0.227). On the basis of this study, sexual activities generally increased accordingly as the beginning of masturbation was earlier. Coital incidence in this study was 67.7% for young males in Korean military service, and 21.5% of them had their first sexual intercourse with prostitutes. Prostitution still plays an important role in the sexual lives of males in Korea. The incidence of STD was over 10% and homosexual manifestation was seen in 1.07% of subjects. Thus a proper and sound sex education at school during childhood is needed in Korea. A large scale survey of sexual behavior in various populations is essential for the improvement of correct sexual concepts.

PURPOSE: For the current article an examination was done as to whether engaging in sexual intercourse before or during adolescence has a negative impact on the suicidal behaviors of suicide ideation, suicide attempt, and suicide lethality and whether the impact varies according to the context of sexual intercourse and/or gender METHODS: Adolescents who experienced casual sex and romantic sex were compared to adolescents who retained their virginity. Data was from samples drawn from the three waves (2010~2012) of the Korea Youth Risk Behavior Web-Based Survey. Logistic models were used to adjust for a wide array of confounding variables. RESULTS: Any type of sexual intercourse increases risk of all suicidal behaviors. Sexual intercourse in a romantic relationship exhibits enhanced risk of suicidal behaviors compared to casual sex. Adjusting for experience of sexual violence, however, decreases risk of romantic sex substantially, turning some estimates statistically insignificant. In addition, risks for suicide lethality are greater for girls than boys. CONCLUSION: Romantic sex put adolescents at higher risk for suicidal behaviors than casual sex owing to prevalent sexual violence in the relationships. Girls suffer more substantively adverse outcomes than boys. These results suggest that adolescents will benefit from comprehensive education on sexuality and sexual behaviors regarding how to form and maintain a romantic relationship that is characterized by personal integrity and mutual respect. It is also important to help victims of sexual violence recover from traumatic events by providing emotional support and effective counseling.

PURPOSE: The purpose of this study was to survey the health behaviors related to reproductive health, reproductive health history, and sexual behaviors of college students in local areas. METHOD: With a survey design, 792 college students from C and D areas were recruited to assess health behaviors such as smoking and alcohol drinking, as well as history of reproductive health and sexual behaviors. The data were collected by a self-administered questionnaire from November to December, 2007. RESULT: Mean age of the students was 20.8(SD=1.96) and gender distribution was 29.2% for male and 70.8% for female. Unhealthy behaviors were alcohol drinking, smoking, excessive weight loss, and irregular exercise; unsafe sex practices were experience of sexual intercourse with multiple sex partners and history of sexually transmitted disease (STD). Male students had more alcohol drinking (p=.04), smoking(p<.001), excessive weight loss(p=.01), experience of sexual intercourse with multiple sex partners(p<.001), history of STD(p=.025) compared to females. On the other hands, female students participated in regular exercise less than males(p<.001). CONCLUSION: College students seem to perform unhealthy behaviors related to reproductive health and less effective way of safe sex practices. Therefore, a planned education program for reproductive health promotion operated by college level is needed to assess and improve the level of reproductive health in college students.

The purpose of this study was to identify the need for sex education in middle school students. Research subjects were 194 students who attended at 1 seminary in B city. The period of data collection was from July to August, 2001. Research instrument was composed of 61 structured items : 17 items related to demographics and sex, 44 items related to the need of sex education. Data were collected through the self-report method by the researcher and one trained assistant. The instrument developed by the researchers was employed to measure the need of sex education and it's Cronbach's alpha = 0.9349 in this research. Data were analyzed by frequency, percentage factor analysis and t-test using SPSS WIN Program. The findings of this study are summarized as follows: 1. The highest score among characteristics of sex was 'less interest about sex(42.6%)', 39.0% of subjects got information about sex from friends or elders. 52.3% of subjects consulted friends or elders about sex problems. The number of sex education lessons was 1-2 times in school during last semester(61.0%). Education by the school nurse was 35.9% to students. 43.1% of subjects announced moderate satisfaction on sex education. 2. The mean score of the need for sex education was 2.88+/-0.47(lowest value 1, highest 4). The most wanted sex education factor was 'chastity and sexual responsibility(3.33+/-0.67)' and followed by 'family and marriage(3.26+/-0.62)' and 'considerations of sex(3.07+/-0.69)'. Meanwhile, the lowest wanted sex education factor is 'physiological characteristics of male (2.47+/-0. 72)', followed by 'sexual behavior (2.49+/-0.75)'. The most wanted sex education item was 'the meaning of family(3.54+/-0.75)' and followed by 'the cautions to prevention from sexual abuse (3.49+/-0.78)' and sexual activity and responsibility(3.43+/-0.77)'. Meanwhile, the lowest wanted sex education item is 'masturbation(2.16+/-0.97)', followed by 'circumcision(2.32+/-0.97)'. 3. There is no significant difference between boys and girls in mean score about the need for sex education(t=- .715, p= .476). Sex education factor that girl-students wanted was 'physiological caracteristics of female'. Sex education factor that boy-students wanted was 'family and marriage'. Sex education items that girl-students wanted were 'cautions during menstruation', 'the relation of ovulation and pregnancy', 'caution to prevention from sexual abuse' and 'sexual behavior and responsibility'. Sex education items that boy-students wanted were 'the meaning of family', 'the importance of marriage', 'male's sex organs', 'a wet dream', 'the method to resolve sexual curiosity', 'sexual intercourse' and 'the connection with the other sex'. In conclusion, the mean score of the need for sex education is medium. The route to attain knowledge about sex and sexual problem is through consulting friends and elders. Therefore, it is necessary to give sex education that is suitable to the subject's needs and methods. Also, it is necessary to give differently strong point about sex education between female and male students.

PURPOSE: This study was done to identify contraceptive practices in adolescent girls in South Korea and predictors of contraceptive practices. METHODS: The study sample included 743 girls who had experienced sexual activity. Using statistics from the 12th (2016) Korea Youth Risk Behavior Web-based Survey, hierarchical logistic regression analysis was conducted. RESULTS: The contraceptive practice rate for adolescent girls was 34%. Contraceptive practice was associated with ‘age at first intercourse’ and ‘sexual intercourse after drinking’. For adolescent girls who had early sexual initiation and drank alcohol before sexual intercourse there was a tendency to reduce the practice of contraception. CONCLUSION: It is necessary to provide practical sex education to improve the practice of contraception in these adolescents. In addition, adolescent girls should be encourage to delay their first intercourse. The results of this study can also be used to develop education interventions regarding healthy sexuality behaviour including the practice of contraception.

OBJECTIVETo explore the pattern of transmission of human immunodeficiency virus through risky sexual behaviors (RSB) in floating workers coming from the countryside to the cities.

METHODSData were collected anonymously through a structured questionnaire survey in 1595 men from Hangzhou and Guangzhou cities, using a multi-stage sampling method. Data from both preliminary analyses and multivariate regression analysis would show the cumulative adoption of RSB over time and the identification of factors associated with the adoption in this population from the two areas.

RESULTS57.9% - 88.1% of the study samples with the pre-stage RSB (receiving shampoo, massage or leisure-seeking activities from "sexual workers") and 79.9% of those with commercial RSB were initiated during the period when they were working away from their home-towns. The highest adoption rate (15.2% - 26.8%) was happened in the third month after moving to the urban areas for pre-stage RSB, while the highest rate (14.4%) was noticed in the sixth month for the commercial ones. The transition interval between the two behaviors was around 3 months. The cumulative rate was peaked from 57.3% to 70.4% for pre-stage RSB and 48.9% for commercial RSB. The cumulative adoption curves showed that the robust increment was more pronounced in the pre-stage than in the commercial RSB. Most of the early adopters were married and holding higher hedonistic beliefs for the commercial RSB. Communication of sex information and behavioral adoption of RSB was associated with the perceived stress and hedonistic beliefs.

CONCLUSIONRSB epidemics seemed to be social and group phenomena, suggesting that related social strategies should be developed in order to control the RSB in this population.

OBJECTIVEUsing quantitative genetic analysis of twin study design to explore the impact of genetic and environmental factors on the prosocial behaviors of children.

METHODSOne hundred and forty-seven twin pairs from Chengdu area aged 6-16 were studied using parental information of Strengths and Difficulties Questionnaire (SDQ). SPSS13.0 and Mx software were used to analyze data, including nonparametric test, Pearson correlation, genetic analyses, etc.

RESULTS(1) Female children score higher than males on their prosocial behavior (Ps< 0.05), except less than 11 age group; (2) Shared environmental factors were the most important for children's prosocial behaviors(C=0.48,95%CI:0.09-0.73),then the genetic factors (A=0.27,95%CI:0-0.66) and the unshared environmental factors(E=0.25,95%CI:0.18-0.35); (3)Female and those who scored higher on their fact/ideal family adaptability and cohesion scored higher in their prosocial behaviors (r:0.17-0.29). On the contrary, those who had extreme conditions during pregnancy/ perinatal period or whose caretaker had discordant opinions on parenting scored lower (r: -0.16 to 0.28).

CONCLUSIONChildren's prosocial behaviors were influenced by genetic and environmental factors including family function and parenting environment, and genetic impact differs in different age and sex.
