The purpose of the present investigation was to evaluate changes in contraceptional habits or sexual activity among adolescents as a consequence of the AIDS-campaigns. In 1986 and 1993 all pupils in their ninth school year in the municipality of Viborg answered an identical questionnaire concerning the mentioned subjects. Both in 1986 and 1993 one third had had sexual intercourse, and one seventh had had their sexual debut before the age of 15. There were significantly more condom users at the first coitus in 1993 and fewer pill users. The proportion of unprotected intercourse did not differ. More pupils had had experience using condoms in 1993, but, as in 1986, nearly half of the girls had used coitus interruptus or safe periods. The proportion of girls who had had intercourse within a week of answering the questionnaire increased from 26% to 42%, indicating a more sexually active population of girls. It is concluded that the increased sexual activity, the fewer pill users and the persisting large proportion of un- or low-protected intercourse may result in more unintended pregnancies. The coincident use of pill and condom should be encouraged.
本调查的目的是评估艾滋病宣传活动对青少年避孕习惯或性行为的影响。1986年和1993年，维堡市所有九年级学生都回答了一份关于上述主题的相同问卷。1986年和1993年，均有三分之一的学生有过性行为，七分之一的学生在15岁之前首次发生性行为。1993年首次性交时使用避孕套的人明显增多，而使用避孕药的人减少。无保护性行为的比例没有差异。1993年有更多学生有使用避孕套的经历，但与1986年一样，近一半的女孩采用过体外射精或安全期避孕法。在回答问卷一周内有过性行为的女孩比例从26%增至42%，这表明女孩的性活动更为频繁。研究得出结论，性活动增加、使用避孕药的人减少以及未采取保护措施或保护措施不力的性行为比例居高不下，可能会导致更多意外怀孕。应鼓励同时使用避孕药和避孕套。
