Assessing risk factors for pregnancy in an adolescent school population.
A cross-sectional observational study was carried out on 7,068 adolescents whose ages ranged from 11 to 20 years who were attending 14 public schools in Bogotá and the surrounding municipalities. A self-questionnaire was administered focusing on socio-demographic, family and sentimental factors and the adolescents' knowledge, attitudes and practices regarding sexuality.
The average age was 15.3 years. 80 % had received family-planning in-formation; 32 % recognised the menstrual cycle. The prevalence of sexual activity was 40 % and 20 % were leading a sexually-active life. The prevalence of pregnancy was 4 % and the declared abortion rate was 1%. The risk factors involved not having received information about family-planning compared to understanding family-planning but with some doubts (OR 0.1: 0.03 to 0.4 95 % CI), previous abortion (OR 7.8: 2.3 to 25.8 95 % CI), not having planned against pregnancy during the first sexual relationship (OR 3.9: 2.2-7 95 % CI). Self-esteem, relationship with parents and perception of the future were not identified as being risk factors.
Teenage pregnancy seemed to be an accidental situation due to lack of knowledge rather than occurring because some teenagers were having trouble.
评估青少年学生群体中怀孕的风险因素。
对7068名年龄在11至20岁之间、就读于波哥大及周边市镇14所公立学校的青少年进行了一项横断面观察研究。采用了一份自填问卷，重点关注社会人口学、家庭和情感因素，以及青少年对性的知识、态度和行为。
平均年龄为15.3岁。80%的人接受过计划生育信息；32%的人认识月经周期。性活动的发生率为40%，20%的人过着性活跃的生活。怀孕的发生率为4%，宣称的流产率为1%。风险因素包括与理解计划生育但有一些疑问相比未接受计划生育信息（比值比0.1：0.03至0.4，95%置信区间）、既往流产（比值比7.8：2.3至25.8，95%置信区间）、首次发生性关系时未采取避孕措施（比值比3.9：2.2至7，95%置信区间）。自尊、与父母的关系以及对未来的看法未被确定为风险因素。
青少年怀孕似乎是由于知识缺乏导致的意外情况，而非因为一些青少年存在问题。
