Condom Use Among Young Women in Australia Using Long-acting Reversible Contraceptives or Other Hormonal Contraceptives

Methods: Women aged 16-24 years attending a sexual and reproductive health centre in Melbourne, Australia, completed a survey about contraceptives and sexual practices. The proportion of LARC and non-LARC hormonal contraceptive users using condoms was calculated and logistic regression compared condom use between the two groups. Condom use was based on frequency of use and coded as a binary variable 'never, not usually or sometimes' versus 'usually or always'.

Results: In all, 294 (97%) women participated in the study; 23.8% (95% confidence interval (CI) 19.0-29.1%) used LARC and 41.7% (95% CI 36.0-47.6%) used non-LARC hormonal contraceptives. Condom use was reported by 26.1% (95% CI 16.3-38.1%) of LARC users and by 27.8% (95% CI 19.9-37.0%) of non-LARC hormonal contraceptive users. There was no difference in condom use between groups (odds ratio (OR) 0.9; 95% CI 0.4-1.9). Condom use reduced with increasing relationship length (≥6 months vs no relationship: OR 0.2; 95% CI 0.1-0.6). Non-LARC hormonal contraceptive users were more motivated to use condoms if worried about pregnancy than LARC users (62.8% vs 47.8%; P = 0.04).

Conclusion: Condom use was low and similar between users of LARC and non-LARC hormonal contraceptives, and was associated with the length of the relationship. These results highlight the need to promote condom use when prescribing LARCs and non-LARC hormonal contraceptives to reduce the risk of STIs.
