The European Journal of Contraception and Reproductive Health Care, February 2010;15:31–34 The use of the vaginal ring and transdermal patch among adolescent girls in Finland Kobra Falah-Hassani*, Elise Kosunen{, Rahman Shiri* and Arja Rimpela* ¨ *Tampere School of Public Health, and {Medical School, University of Tampere, Tampere, FinlandEur J Contracept Reprod Health Care Downloaded from by HINARI on 07/31/10 ........................................................................................................................................................................................................... ABSTRACT Objective Little is known about the use of the vaginal ring and transdermal patch in representative adolescent populations although these contraceptives are supposed to be a good option for that age group. The aim of this study was to determine the use of the vaginal ring and that of the transdermal patch and to compare these with the use of oral contraceptives (OCs) and emergency contraception in adolescent girls residing in Finland. Methods As part of the Adolescent Health and Lifestyle Survey a questionnaire was mailed to a representative sample of girls aged 14, 16 or 18 years residing in Finland. Of these 3029 (72%) responded. For personal use only. Results The use of the vaginal ring (0.9%) and that of the transdermal patch (0.1%) were uncommon whereas OCs were commonly resorted to (20%). Only 0.6% of girls aged 16 and 2.5% of those aged 18 used the vaginal ring or the transdermal patch. Fifteen percent of girls had ever used emergency contraception. Conclusion The vaginal ring and the transdermal patch are rarely used by adolescents. Our findings suggest that these novel contraceptive methods have not been adopted by family planning services.

  • 3. Use of the vaginal ring and transdermal patch Falah-Hassani et al. RESULTS regarding knowledge of girls about the ring and the patch was not obtained. Among American girls aged Overall 21% of the girls were current users of a pill, 14–21 years11, 52% were unaware of the existence of the vaginal ring or the transdermal patch (Table 1). the vaginal ring. Of those who were, only 35% had The use of OCs was much more commonly reported sufficient knowledge. Further studies on awareness than that of the vaginal ring or the transdermal patch. of these new methods among potential users are The use of all hormonal contraceptives, except that of needed. the transdermal patch, increased with age. There may be other reasons for the infrequent use Among current users of hormonal contraceptives of the vaginal ring and the transdermal patch.

The figures the current users of hormonal contraceptives, 43.2% were similar to those in 2003 that we reported had ever resorted to EC. previously9. Obviously, the use of the patch and that of the ring were so infrequent that they could not possibly have affected the need for EC. DISCUSSION Our study had strengths and limitations.
