According to World Health Organization (WHO), adolescents are persons aged 10-19 years. They comprise nearly half of the world's population of about 7 billion and 85% of them live in developing countries.
The aim of this study is to assess the sexual behaviours, practices and contraceptive use among secondary school adolescents in Elele, Rivers State, Nigeria.
A cross-sectional descriptive study of 300 in-school adolescents in a rural community in Rivers State, South-South Nigeria, selected using multi-stage random sampling technique.
There was a high awareness of contraception among respondents, 235 (78.3%), with condom, 207 (88.1%), having the highest awareness. About forty-five percent of respondents, (134), in this survey have had their first sexual debut and 84.3% of this number was sexually active in the last six months preceding this survey. The mean, median and the modal age of first sexual debut were; 12.0 + 2.8, 12.6, and 12.4 years respectively with the youngest age of initiation of sexual activity being 5 years. About two-thirds of those sexually active have multiple sexual partners. Contraceptive use was statistically higher among the sexually active respondents, (74.3%), than the sample study population, (30.3%), (Χ2 = 65.08, p = 0.000). Condom use at their last sexual debut, (58.2%), was significantly higher than use in their first sexual debut (31.3%), (Χ2 = 16.17, p = 0.000). The most commonly used contraceptive method was condom, (81.7%). CoNCLUSION: High risk sexual behaviour and increased sexual activity was prevalent in this age group. Efforts to promote sexuality education and contraceptive awareness should be intensified.
根据世界卫生组织（WHO）的定义，青少年是指年龄在10至19岁之间的人群。他们占世界约70亿人口的近一半，其中85%生活在发展中国家。
本研究旨在评估尼日利亚河流州埃莱莱地区中学青少年的性行为、性习惯及避孕措施使用情况。
采用多阶段随机抽样技术，对尼日利亚南南地区河流州一个农村社区的300名在校青少年进行横断面描述性研究。
受访者对避孕措施的知晓率较高，有235人（78.3%）知晓，其中对避孕套的知晓率最高，为207人（88.1%）。本次调查中约45%的受访者（134人）首次发生性行为，其中84.3%在本次调查前的六个月内有性行为。首次性行为的平均年龄、中位数年龄和众数年龄分别为12.0 + 2.8岁、12.6岁和12.4岁，最早开始性行为的年龄为5岁。约三分之二有性行为的人有多个性伴侣。有性行为的受访者中避孕措施的使用率在统计学上高于样本研究人群（74.3%比30.3%）（Χ2 = 65.08，p = 0.000）。他们最近一次性行为时避孕套的使用率（58.2%）显著高于首次性行为时的使用率（31.3%）（Χ2 = 16.17，p = 0.000）。最常用的避孕方法是避孕套（81.7%）。
该年龄组中高风险性行为和性活动增加的情况普遍存在。应加强促进性教育和避孕意识的努力。
