Reported side effects from hormonal contraceptives among those seeking abortion care versus contraceptive services.

Introduction: We aim to describe and compare the prevalence of subjective side effects associated with hormonal contraceptive use among reproductive healthcare users seeking either abortion care or contraceptive services.

Methods: This substudy derives from a previously reported cross-sectional survey involving 1006 users of public reproductive healthcare services in the Helsinki metropolitan area in Finland. We included all 813 respondents with a history of hormonal contraceptive use (mean age 27 years, IQR 24-33 for abortion care; 24 years, IQR 19-30 for contraceptive services).
