Emergency contraception among teenagers in Switzerland: a cross-sectional survey on the sexuality of 16- to 20-year-olds.
OBJECTIVE
To describe and analyze emergency contraception (EC) awareness and use among sexually active Swiss teenagers.


METHODS
Anonymous computerized questionnaires were distributed to a national representative sample of 4283 in-school adolescents (aged 16 to 20 years) in high schools and professional centers. Young people who were sexually active (51.5% of the sample: 1058 girls and 1073 boys) responded to questions on EC awareness and use and on sexual perception, attitude, and behaviors. Univariate analyses and multiple regression analyses were used to describe EC awareness and use and their correlates.


RESULTS
Most of the sexually active girls (89.3%) and boys (75.2%) knew of the existence of EC. Of girls, 20% reported having used EC, and the majority of them used it only once (64.1%) or twice (18.5%). EC awareness was positively associated with the father's level of education (girls: odd ratio 5.18) and the scholastic curriculum of the respondent. Gender differences in the correlates of EC awareness demonstrate that girls who had a confidant or a group of friends or boys of Swiss nationality and those who have had the opportunity to discuss the issue of contraception declare greater awareness of EC. EC use was higher among girls who lived in urban areas (odds ratio 1.91) and occasionally had unprotected intercourse. We did not find any significant difference in the profile of multiple vs. one-time users.


CONCLUSIONS
EC awareness and use should be improved through better information and accessibility, especially among teenagers who place themselves in at-risk situations.
