Uso de la anticoncepción con solo gestágenos en atención primaria: estudio GESTAGAP

Abstract

AimTo estimate the prevalence of use of progestin-only contraceptive among women who request reversible contraception in Primary Care (PC). DesignMulticentre cross-sectional study. SettingPrimary Care Health Care Centres (Madrid). ParticipantsWomen aged 16-50 years old, users of reversible contraception, who speak Spanish, and had attended the Primary Care Centre in the last year. Main measurementsPrimary outcome: contraceptive method used: Contraception with progestins-only (yes/no). Age, parity, country of origin, type of contraceptive method used, reason for choice, source of information, satisfaction with the contraceptive method. Telephone survey. ResultsA total of 417 women were interviewed. The median age was 30.3years (SD: 7.7). Spanish 69%, and 82% of participants had secondary or university studies. More than half (57%) were nulliparous. The type of contraceptive used included: progestins only: 14%, combined hormonal contraceptive: 74%, copper IUD: 2%, and condom 10%. The prevalence of use of “progestins-only” was 13.9% (95%CI: 10.6-17.2). Medroxyprogesterone acetate injection was the most progestin-only method used (4.6%), desogestrel oral pill (4.1%), IUD-levonorgestrel IUD (3.9%), and etonogestrel subdermal implant (1.9%). The family doctor was the prescriber in 71% of the women. Satisfaction: high (range 9-10). Using only progestogens was associated with older age, being non-Spanish, breastfeeding, and having a medical contraindication for combined contraception (P<0.05). ConclusionsThe prevalence of use for progestins was 14%, satisfaction was very high for all contraceptive methods. The user profile for the only progestins-only corresponds to older, and non-Spanish women with conditions such as breastfeeding or contraindications for other contraceptives.
