Latent class analysis was employed to characterize women's contraceptive choices; multinomial logistic regression was used to evaluate correlates of membership in the identified classes.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The vast majority of women (96%) reported using one or more contraceptives, most commonly short\u2010acting hormonal methods (60%), barrier methods (38%), long\u2010acting contraceptives (16%) and withdrawal (15%). In total, 32 combinations were reported. Four latent classes of method use were identified: no contraception (4% of women); short\u2010acting hormonal methods with supplementation (59%, mostly the pill); high\u2010efficacy contraceptives with supplementation (15%, all long\u2010acting reversible contraceptive users); and low\u2010efficacy contraceptive combinations (21%); supplementation usually involved barrier methods or withdrawal. Class membership differed according to women's characteristics; for example, women who had ever been pregnant were more likely than other women to be in the no\u2010contraception, high\u2010efficacy contraceptive or low\u2010efficacy contraceptive combination classes than in the short\u2010acting hormonal contraceptive class (odds ratios,
