ABSTRACT: Objective: To evaluate the profile of the
Brazilianvaginal ring user, reasons for choosing it, satisfaction, menstrual
pattern, tolerability, efficacy, side effects and
reasons for discontinuation. Methods: We reviewed the files of 148 users
who attended the Hospital de Jacarepaguáand private clinics, between 2005 and
2011, in a total of 3107 cycles. Kaplan-Meier survival curves and regression
models were used in statistical analysis. Results: The profile was: single,
nulligravida, 30 years (mean) and with university education. The previous
contraception used was mostly the oral hormonal contraception (75.7%). Women
chose the ring for: practicality (32.4%), forgetting the pill (32.4%) and irregular
vaginal bleeding (13.5%). The satisfaction
degree was 80.5% (119). There were good cycle control and
no pregnancies. Thirty-eight patients discontinued the use (25.7%). The main
reasons were wish for pregnancy (6%),
spotting (3.4%) and increased vaginal discharge (2.7%). At the end of
the first year, use of the greatest reduction of continuity probability was
observed (19.3%). Women with side effects were 68% less likely to be satisfied
with the method than those without (p-value Conclusion: Nuvaring® is an excellent contraceptiveoption due to its sefficacy, cycle control,
tolerability, practicality and safety.
