“…While very effective if used consistently, these methods are subject to failure because of inconsistent or errors of use (failure rates among pill and condom users are 9% and 18%, respectively) (Trussell, 2011). In Brazil, the lack of trained professionals and limited contraceptive options (Heilborn et al, 2009;Vieira, Souza, 2011) contribute to skewed contraceptive distribution favoring user dependent methods (Moura, Silva, Galvão, 2007). Long-acting reversible contraception (LARC) such as implant or intrauterine device (IUD) are more effective (failure rates are 0.05% and 0.8%, respectively (Trussell, 2011), but they are seldom used in Brazil (0.1% and 1.9%, respectively) (Brasil, 2008a).…”
