Adolescents exhibit numerous risky sexual behaviors leading to initiation of sexual intercourse not mindful of the many consequences.
To determine the prevalence and pattern of sexual risky behavior and its association with sexual initiation.
This was a school-based descriptive cross-sectional study among 377 in-school adolescents, who were selected using multistage sampling methods. Research instruments were semistructured self-administered questionnaires.
The mean age of respondents was 15.7 (+1.8) years. Most of the respondents claimed to have heard about sex education at one time or another. About 53 (14.1%) had their first sexual experience before or at the age of 15 years. The mean age of the first sexual experience for males was 14 years 3 months and 15 years 3 months for females. Fourteen (3.7%) had no fixed sexual partner; most of the sexually active respondents did not use a condom during their last intercourse. Only 7.7% of the respondents reported to have had a sexually transmitted infection. Most of the 207 female respondents (85.5%) had never been pregnant while 88.9% of those who had been pregnant had an abortion. Females were about 1.5 times more likely to have had first sexual intercourse before the age of 15 years, though the observed likelihood was not statistically significant [odd ratio (OR) = 0.7, 95%; confidence interval (CI) = 0.3-1.5; p = 0.642]. Likewise, males were 1.7 times more likely to have used condoms at the last sexual intercourse, and the observed likelihood was not statistically significant (OR = 1.7; 95% CI = 0.8-3.4; p = 0.079).
In this study, adolescents were sexually active with negative consequences on their reproductive health. Stakeholders involved in the care of adolescents should take the consequences into consideration.
青少年表现出许多危险的性行为，导致在未考虑诸多后果的情况下开始性行为。
确定性危险行为的患病率和模式及其与首次性行为的关联。
这是一项基于学校的描述性横断面研究，对377名在校青少年进行了多阶段抽样选取。研究工具为半结构化自填式问卷。
受访者的平均年龄为15.7（±1.8）岁。大多数受访者声称曾听说过性教育。约53人（14.1%）在15岁之前或15岁时首次发生性行为。男性首次性行为的平均年龄为14岁3个月，女性为15岁3个月。14人（3.7%）没有固定性伴侣；大多数有性行为的受访者在最近一次性交时未使用避孕套。只有7.7%的受访者报告曾感染性传播疾病。207名女性受访者中，大多数（85.5%）从未怀孕，而怀孕者中有88.9%进行了堕胎。女性在15岁之前首次发生性行为的可能性约为男性的1.5倍，尽管观察到的可能性无统计学意义[比值比（OR）=0.7，95%；置信区间（CI）=0.3 - 1.5；p = 0.642]。同样，男性在最近一次性交时使用避孕套的可能性为女性的1.7倍，观察到的可能性无统计学意义（OR = 1.7；95% CI = 0.8 - 3.4；p = 0.079）。
在本研究中，青少年性行为活跃，对其生殖健康产生了负面影响。参与青少年护理的利益相关者应考虑到这些后果。
