Easy accessibility and availability of emergency contraception raises contradictory opinions. Education about emergency contraception is resisted because of a fear that it might lead to irresponsible sexual behaviour and repeated use of emergency contraception instead of regular contraception.1
In Finland, sales of emergency contraception (the Yuzpe method) increased 10-fold from 1987 to the mid-1990s. In 1994 a national survey among 18-44 year old women showed that knowledge and use of the method was concentrated in the youngest respondents.2 Reports from other countries confirm that young women and even teenagers are well aware of the method.3,4 However, only a few reports have been published on use of emergency contraception among adolescents. We studied knowledge of emergency contraception and frequency of use among teenagers.
Participants, methods, and results
The school health promotion study was introduced to provide data on adolescent health behaviours in Finland. Regional and local school authorities were told about the study, and 96 out of 452 municipalities joined it in 1996. Pupils anonymously completed a structured questionnaire during one lesson under the supervision of their teacher and enclosed the questionnaire in an envelope directed to the research group.
The total number of respondents was 52 700, and the response rate was 88-91% for comprehensive schools and 82% for upper secondary schools. We report here data on girls in comprehensive schools born in 1981 (mean age 14.8 years, range 14.3-15.2) and 1980 (15.8 years, range 15.3-16.2) and girls in upper secondary schools born in 1978 (17.8 years, 17.3-18.2); the total number of girls was 21 940.
The question on emergency contraception asked: “Have you ever used emergency contraception?” Alternative responses were: (1) No; (2) Yes. How many times altogether? Number of times? or (3) I do not know what emergency contraception is. The questionnaire also asked whether the respondent had ever had sexual intercourse.
Only 3% of the 14-15 year olds and 1.5% of the 17 year olds did not know what emergency contraception was (table). The proportion of girls who had used emergency contraception increased with age from 2.1% to 15.1%. About two thirds of all girls who had used emergency contraception had used it only once (table). The proportion of multiple users did not suggest any systematic increase with age.
In comprehensive schools, 13.3% of 14 year olds and 28.8% of 15 year olds had had sexual intercourse at least once, while among 17 year olds the prevalence was 51.5%.
Comment
In Finland, emergency contraception is delivered as a part of primary health care in local health centres and family planning clinics.5 Adolescents get information on contraception in sex education lessons at schools. School health care advises on problems of sexuality, including need of emergency contraception.
The adolescent girls were widely aware of emergency contraception, which is consistent with results for younger women in other countries.3,4 We only asked about knowledge of the existence of the method: the results may not indicate that adolescents were well informed of details of its use. British studies have shown that although adolescents know about emergency contraception, they are unclear how to obtain the pills and how to use them.3 4
Emergency contraception has not become a contraceptive choice replacing conventional methods among adolescents. Only a small proportion of teenagers had used emergency contraception repeatedly. Our results suggest that easy access to contraceptive services (including emergency contraception) and intensive sex education have not increased adolescent sexual activity. The proportion of sexually experienced teenagers in our study was not higher than in Finnish studies in the late 1980s or early 1990s when emergency contraception was not widely used.
