All demographic and behavior data were collected through interview by public health nurses. All analyses were performed with SPSS for Windows (version 15.0) using chi\u2010square test, survival analyses and logistic regression. <jats:italic>Main outcome measure.<\/jats:italic> New sexual male partners. <jats:italic>Results.<\/jats:italic> Four out of five girls (80%) did not have any new partner during the study period of 12 months. From survival analyses the 12\u2010month incidence rate were 29.8 (95% CI: 25.3\u201334.1) and 10.6 per 100\u2010women months (95% CI: 7.3\u201313.9) for one or two or more partners, respectively. Predictors of partner change were partner change during the last six month prior study start, being single and sexual debut within three years after menarche. <jats:italic>Conclusion.<\/jats:italic> Being in a regular relationship with a boyfriend reduce considerably the risk of having a new sexual partner. Recent history of partner change is the strongest predictor of future partner change.<\/jats:p>","DOI":"10.1080\/00016340802422339","type":"journal-article","created":{"date-parts":[[2008,9,16]],"date-time":"2008-09-16T23:50:23Z","timestamp":1221609023000},"page":"1071-1076","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Partner change among Norwegian teenage girls attending youth health clinics"],"prefix":"10.1111","volume":"87","author":[{"given":"FINN EGIL","family":"SKJELDESTAD","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"STINE","family":"NILSEN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2010,12,31]]},"reference":[{"key":"e_1_2_7_2_2","first-page":"3006","article-title":"New patterns of sexual behaviour among adolescents","volume":"123","author":"Pedersen W","year":"2003","journal-title":"Tidsskr Nor Laegeforen"},{"key":"e_1_2_7_3_2","first-page":"1756","article-title":"Mobile phones, web chat, and sex: a study of Norwegian adolescents based on a representative sample","volume":"124","author":"Pedersen W","year":"2004","journal-title":"Tidsskr Nor Laegeforen"},{"key":"e_1_2_7_4_2","first-page":"1769","article-title":"Adolescent sexuality in rural Norway 1997\u20132001","volume":"124","author":"Breidablikk HJ","year":"2004","journal-title":"Tidsskr Nor Laegeforen"},{"key":"e_1_2_7_5_2","first-page":"3021","article-title":"Age at first intercourse among Norwegian adolescents","volume":"110","author":"Kraft P","year":"1990","journal-title":"Tidsskr Nor Laegeforen"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02438166"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a009161"},{"key":"e_1_2_7_8_2","first-page":"1276","article-title":"Early sexual debute as an indicator of sexual risk behaviour","volume":"89","author":"Persson E","year":"1992","journal-title":"J Swed Med Ass"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.3109\/00016349609033359"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.2307\/2991502"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.5993\/AJHB.28.1.1"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1054-139X(99)00051-8"},{"key":"e_1_2_7_13_2","first-page":"1","article-title":"Adolescents: is there an association between knowledge of oral contraceptives and profession of provider?","volume":"13","author":"Hansen T","year":"2007","journal-title":"Eur J Contracept Reprod Health Care"},{"key":"e_1_2_7_14_2","unstructured":"DarrochJEFrostJJSinghSCan more progress be made?
