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). The study followed STROBE guidelines.

RESULTS

Altogether 400 respondents sought abortion care, while 413 sought contraceptive services (counselling, prescription renewal, symptoms and/or dissatisfaction with their contraceptive method). Combined oral contraceptives and progestin-only pills were the most used methods in both groups. Respondents seeking abortion care reported contraception-associated weight changes, sex-related problems, mood changes, and acne more frequently than those seeking contraceptive services (p-value<0.05 for all). Some 52% of respondents seeking abortion care reported mood changes compared with 29% of those seeking contraceptive services, with a crude OR of 2.7 (95% CI 2.00 to 3.57). After adjustment, the OR for reporting mood changes among respondents seeking abortion care was 1.5 (95% CI 1.05 to 2.23).

CONCLUSIONS

Mood changes associated with hormonal contraceptive use were the most frequently reported side effect among all respondents. These findings suggest a need for individualised counselling on mood-related side effects as mood changes may contribute to higher discontinuation rates.
