“…Unintended pregnancies are a major health problem for women in developed and developing countries [1][2][3]. Many of these unintended pregnancies are due to discontinuation of contraceptive methods and, in turn, discontinuation is often due to side effects [2,4].…”

Background:The aim was to compare the efficacy and acceptability of two Internet-based fertility awareness based methods of family planning (FABM).Study Design: Six hundred and sixty-seven women and their male partners were randomized into either an electronic hormonal fertility monitor (EHFM) group or a cervical mucus monitoring (CMM) group. Both groups utilized a web site with instructions, charts, and support.Acceptability was assessed online at 1, 3, and 6 months. Pregnancy rates were determined by survival analysis. Results:The EHFM participants (N=197) had a total pregnancy rate of 7 per 100 users over 12 months of use compared with 18.5 for the CMM group (N=160). The log rank survival test showed a significant difference (p < .01) in survival functions. Mean acceptability for both groups increased significantly over time (p < .0001). Continuation rates at 12 months for the monitor group were 40.6% and the mucus group 36.6%. Conclusion:In comparison with the CMM, the EHFM method of family planning was more effective. All users had an increase in acceptability over time. Results are tempered by the high drop-out rate.

“…Dados similares têm sido observados no Brasil onde 45% das usuárias de ACO descontinuaram o uso nos primeiros 12 meses, sendo 12% por eventos adversos, embora esta proporção seja maior para injetáveis (64%) 10 . Embora ACO com menor dose de estrogênio estejam disponíveis no mercado brasileiro e estas novas formulações tenham sido desenvolvidas para minimizar os eventos adversos e aumentar a continuidade de uso, isto não tem ocorrido devido à maior taxa de sangramento irregular que provocam 11 .…”

Fatores associados à descontinuação do uso de anticoncepcionais orais combinados Associated factors with discontinuation use of combined oral contraceptives Artigo originalResumo OBJETIVO: Avaliar as razões para descontinuar diversos anticoncepcionais orais combinados entre mulheres brasileiras iniciantes do método, residentes em áreas urbanas. MÉTODOS: Estudo de corte transversal com 400 ginecologistas do Brasil, registrados na Federação Brasileira de Ginecologia e Obstetrícia. Cada médico entrevistou 10 mulheres não grávidas, não lactantes, não em amenorreia, com idades entre 18 e 39 anos que consultavam solicitando anticoncepcional oral combinado (ACO), com um questionário no início de uso e aos 6 meses posteriores. O questionário incluiu dados sociodemográficos, tipo de ACO escolhido ou prescrito e razões para descontinuação, caso ocorresse durante o seguimento. A estratégia de seleção permitiu a inclusão de mulheres de diferentes estratos socioeconômicos, mas somente atendidas em consultórios privados ou de convênios. O tamanho da amostra foi estimado em 1.427 mulheres. RESULTADOS: Foram obtidas 3.465 entrevistas na primeira visita e 1.699 aos 6 meses posteriores. As mulheres tinham predominantemente entre 20 e 29 anos, 57,3% eram solteiras e em proporção quase igual de 45% tinham ensino médio ou superior. A maioria (60,7%) era nuligestas e dentre as que tinham usado algum método contraceptivo anteriormente, 71,8% tinham utilizado ACO. Entre os ACO mais prescritos ou escolhidos, o mais prevalente foram os monofásicos com etinilestradiol (20 µg) e no tocante ao progestágeno, o mais prevalente foi com gestodeno (36,5%), seguido por ACO com drosperinona (22,0%). Aos 6 meses, 63,5% continuavam em uso do ACO. Dentre as que descontinuaram o uso, as principais razões dadas foram: desejo de engravidar (36,5%) e efeitos colaterais (57,3%) como cefaléia (37,6%), aumento de peso (16,6%) e sangramento irregular (23,6%). CONCLUSÕES: A taxa de continuação do uso de ACO foi baixa aos seis meses e este estudo pode contribuir para que os médicos orientem melhor suas pacientes iniciantes no uso de ACO sobre os eventos adversos esperados que são mínimos e temporários e sobre os benefícios não contraceptivos dos ACO.Abstract PURPOSE: Due to the scarce information available in Brazil in relation to the number of women who initiated the use of combined oral contraceptives and prematurely discontinued, the objective was to assess the reasons for discontinuation of the use of several combined oral contraceptives among Brazilian women living in urban areas. METHODS: A crosssectional study with 400 gynecologists registered withy the Brazilian Federation of Obstetricians and Gynecologists. Each physician interviewed 10 non-pregnant, not breastfeeding, not amenorrheic women aged 18 to 39 years who consulted requesting combined oral contraceptive (COC) with a questionnaire at the beginning of use and at six months later. The questionnaire included sociodemographic data, type of COC chosen or prescribed and reasons for discontinuation w...

“…7 All these situations may contribute to making hormonal methods highly discontinuated. [15][16][17] However, the difference between our findings and others can be explained by two reasons: either Brazilian women are really satisfied with the methods they use, and this finding is quite positive; or women attending our Unified Health System (SUS) may feel that it is not easy to access more effective methods, such as LARC, and this may affect their satisfaction in some way. 14 For example, the high satisfaction of women who use pills and injectable methods may be more related to the fact that they face barriers to full access irreversible methods 18,19 and even LARC, such as hormonal IUDs and implants, that are not even available in SUS.…”
