Similar investigations had been performed earlier, which enabled comparisons. <jats:italic>Results.<\/jats:italic> Almost all women (98%) had experienced intercourse and giving oral sex (94%). Condoms were most often used at first intercourse (72%) and combined oral contraceptives at latest intercourse (67%). The ever use of emergency contraceptive pills had increased from 22% to 52% over five years and there was a tendency towards more risk\u2010taking behavior with more sexual partners (mean 5.4 in 1999 and mean 7.4 in 2004), more experience of first\u2010date intercourse without a condom (37\u201345%), and more self\u2010reported sexually transmitted infections (14\u201321%). The proportion of women who had undergone an abortion remained stable (6%) and fewer women reported ever being sexually harassed in 2004 compared to 1999. <jats:italic>Conclusions.<\/jats:italic> In conclusion, contraceptive use remained stable over time, but there was a trend towards more risky sexual behavior with more sexual partners, more unprotected first\u2010date intercourse, and more self\u2010reported sexually transmitted infections. Induced abortions, however, had not increased, but the use of emergency contraceptive pills had more than doubled in the five years between 1999 and 2004.<\/jats:p>","DOI":"10.1080\/00016340600626941","type":"journal-article","created":{"date-parts":[[2009,12,8]],"date-time":"2009-12-08T17:34:45Z","timestamp":1260293685000},"page":"966-970","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Increased sexual risk taking behavior among Swedish female university students: repeated cross\u2010sectional surveys"],"prefix":"10.1111","volume":"85","author":[{"given":"Margareta","family":"Larsson","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tanja","family":"Tyd\u00e9n","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2010,12,31]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.3109\/00016349109006213"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.3109\/00016349609054675"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1049-3867(00)00096-7"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1054-139X(00)00164-6"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.2002.01239.x"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.contraception.2003.11.013"},{"key":"e_1_2_6_8_2","unstructured":"Swedish Institute for Infectious Disease Control.
