Awareness of the non-contraceptive benefits of reversible contraceptive methods in a cohort of Brazilian women: an exploratory study.

We assess the awareness of Brazilian women about non-contraceptive benefits of contraceptives and compare non-health with health care providers. We conducted a survey in Brazil using a questionnaire administered via Google Forms asking women to respond about the awareness of non-contraceptive benefits of combined oral contraceptives (COCs), depot-medroxyprogesterone acetate (DMPA), 52 mg levonorgestrel-releasing intrauterine system (LNG-IUS), etonogestrel (ENG)-implant, copper intrauterine device (Cu-IUD), and male condom. We received 2,068 completed questionnaires, 720 women (34.8%) aged ≤ 29 years and 236 (11.4%) were physicians or nurses. Only one third of the respondents were aware that COC use is associated with decreased risks of ovarian and endometrial cancers; 296 (16.1%) about that the use of DMPA is associated with a decreased risk of endometrial cancer, and 253 (13.8%) were aware about that the users of the Cu-IUD present lower risk of cervical cancer. We identified significant differences between non-health care providers when compared to physicians or nurses. We found low awareness regarding the associated lower risk of ovarian, endometrial and cervical cancer associated with the use of some contraceptives, evidencing the need to provide more information about the non-contraceptive benefits during training for health care providers.
