A study of the sources of and the changes in the knowledge about contraception, pregnancy, and sexuality during a 21-year-period.
A questionnaire was handed out on the same day in all ninth grade classes in the Municipality of Viborg without prior notice to teachers or pupils. The results were compared with similar studies performed in 1986, 1993, and 2000.
In all 394 of 398 questionnaires were answered. The answers revealed that forty-three percent knew at which time in the cycle pregnancy can occur; boys with sexual debut scored lowest. The time limits for legal abortion were known by 64%, the girls had a higher level of knowledge on this item than the boys. The abortion limits for 16-year-old girls were known by 58%, but here the boys, who had made sexual debut, scored highest and the girls with no prior sexual experience scored lowest. The sources of knowledge changed over the years; screen-based media (TV, internet) now cover more than 30% of both gender's sources, and magazines/pornography comprise more than 50% of girls' and 30% of boys' sources of knowledge. The school's and friends' share in sexual education remained constant, while books and parents as knowledge sources show a downward trend.
School and friends still play a substantial role in the sexual education of ninth grade pupils, but screen-based media and magazines are now the third-most important source of information and their importance have increased considerably over the past seven years. Knowledge of time limits for abortion, early pregnancy signs and cycle has not changed except for slight gender differences.
一项关于21年间避孕、怀孕及性知识的来源与变化的研究。
在未事先通知教师或学生的情况下，于同一天向维堡市所有九年级班级发放问卷。将结果与1986年、1993年和2000年进行的类似研究进行比较。
共发放398份问卷，回收394份。答案显示，43%的人知道在月经周期的哪个时间段可能怀孕；首次性行为的男孩得分最低。64%的人知道合法堕胎的时间限制，在这一项上女孩的知识水平高于男孩。58%的人知道16岁女孩的堕胎限制，但在此项上，有过首次性行为的男孩得分最高，而没有性经验的女孩得分最低。多年来知识来源发生了变化；基于屏幕的媒体（电视、互联网）现在占男女双方知识来源的30%以上，杂志/色情内容占女孩知识来源的50%以上，占男孩知识来源的30%以上。学校和朋友在性教育中的占比保持不变，而书籍和父母作为知识来源呈下降趋势。
学校和朋友在九年级学生的性教育中仍发挥着重要作用，但基于屏幕的媒体和杂志现在是第三重要的信息来源，且在过去七年中其重要性大幅增加。除了轻微的性别差异外，关于堕胎时间限制、早孕迹象和月经周期的知识没有变化。
