Abstract
PURPOSE: This study explores transitions in contraceptive use in early sexual life in France and has three objectives: describe predictors of contraceptive use at first sex with first and second partners, describe contraceptive trajectories in these partnerships, and test associations between use at first sex and switching in first partnership on use with second partner. METHODS: Our analyses include 1,823 participants, aged 15-29 years, of the 2010 French national sexual health survey who reported at least two lifetime sexual partners and a subset of 1,593 people who report contraceptive use throughout their first partnership. We use logistic regression and generalized estimating equation models to investigate the three objectives. RESULTS: Our results reveal a decline in contraceptive use between first and second partner, driven primarily by decreases in condom use, from 87.9% to 79.5% between first and second partner. This is partially offset by an increase in use of effective methods (from 7.8% to 38.1%), particularly by women. Any method use and discontinuation with first partner were predictors of patterns with second partner. CONCLUSIONS: Analysis of early transitions in contraceptive use of adolescents in early sexual life reveals shifts from sexually transmitted infection to pregnancy prevention and an increase in unprotected sex.
