Factors Associated with the Timing of First Sexual Intercourse Among College Students in Busan, Korea

Abstract

= Abstract =Purpose: The purpose of this study was to predict when college students in Korea have their first sexual intercourse and to explore the factors associated with the timing of first sexual intercourse. Materials and Methods:Data are collected by using self-report survey toward total 797 of male and female college students who are currently attending the college in Busan, Korea. Students were divided by four groups according to their age of timing of first sexual intercourse, ＜16 years, between 16 to under 19, over 19 years and non-experienced. To examine the difference of four groups, Chi-square test and ANOVA (analysis of variance) were used. For estimation of the timing of first sexual intercourse we used Kaplan-Meier estimation and for differences of each group we used log-rank test. To identify the factors associated with the timing of first sexual intercourse we used Cox proportional hazards model. Conclusions:This study predicts the timing of first sexual intercourse among college students in Korea. Early sexual debut is an important indicator for continued risk behavior regarding reproductive health.

Assessment of Time of Sexual Initiation and Its Associated Factors among Students in Northwest Ethiopia

“…Males tended to have 2.5 times (AHR= 2.518 , 95% CI: 1.710-3.707) more sexual experience than females in college students in Busan, Korea [43] this disagreement with current study can be attributed by age dissimilarity of study population i.e. 17-36 years [43] vs 15-24 years in current study.…”

“…In this study females were 1.9 times more likely initiating sex at younger age than males and the finding was in line with studies [33,36,52] and contradicts with studies [43,53].…”

“…However, it was slightly higher than studies conducted in Kolladiba, North West Ethiopia (15 years) [36], Gojjam, North West Ethiopia (13.5 years) [50], East Gojjam zone, northwest Ethiopia (13.6 years) [33], Central Scotland (14 years) [51], Brazil (14.9 years) [44], and Peru (14.3 years) [49], and the finding was Lower than a studies in North East Ethiopia (17 years) [36], Butagira, Ethiopia (17years) [45], Gamo Gofa, South West Ethiopia (17.07 years) [41], rural Zimbabwe (18·5 years) [16], and Busan, Korea (21 years for males) [43]. Reasons for differences of figures in prior studies among each other and with current study might be variations in using numerical summary measures i.e.…”

“…College students in Busan, Korea who were alcohol drinkers and smokers were 1.8 times (AHR=1.787, 95% CI: 1.222-2.615) and 1.9 times (AHR=1.958, 95% CI: 1.535-2.498) respectively more likely debut sex at younger age compared their counter parts [43].Youths drinking alcohol in North East Ethiopia were begin sex about 2.2 times (AOR=2.16 , 95% CI: 1.12-4.18) than non-drinkers [36].…”

“…And the finding was higher than combined demographic health survey data between 2000-2010 in subSaharan Africa (25%) [29], in-school adolescents in Eastern Ethiopia (24.8%) [39], high school students in Northern Ethiopia (26.3%) [38] and it was lower when compared with a study in Brazilian adolescents (61.6%) [44], teenagers in United States (about 43% of females and 42% males had beginning sex) [30], youths in North East Ethiopia (51.3%) [36], out-of-school adolescents in Northwest Ethiopia (45%) [33] and Gondar high school students in North West Ethiopia (50%) [25].The possible discrepancy would be differences in age of study participants included in different studies (example 10-19 [33], 15-19 [29], 16-19 [44], 15-24 [36], 17-36 [43]), time gap between the studies, differences in age of marriage in different areas or inclusion/exclusion of married participants which is the main reason for sexual initiation [24,33,45], variations in mass advertisement on sexual abstinence to prevent HIV/AIDS, technological advancements for viewing pornography videos which was risk for early sexual onset [35,36,43,46,47].…”
