Regional inequalities in the use of contraception in Spain: a multilevel approach.

The aim of the present study was to describe the influence of individual and regional socioeconomic factors on the use of contraception among women in Spain in 2006. A cross-sectional study was carried out among women aged 15-49 years (n=5141). The prevalence of contraception use was analyzed as a function of individual and regional characteristics using weighted multilevel logistic regression models. The use of contraception in more deprived regions was lower during first sexual intercourse but higher during the four weeks prior to the interview. Inequalities in the use of contraception were observed among women in Spain after accounting for both individual and regional characteristics.
