Over half the women in Brazil are avoiding pregnancy due to the Zika virus epidemic.
Since the outbreak of Zika in Brazil, there have been 1,845 confirmed cases of congenital Zika syndrome in babies.
A team of doctors, led by Professor Debora Diniz from University of Brasília, wanted to understand how the epidemic has impacted reproductive health practices.
A national survey conducted in June 2016 used face-to-face questionnaires to collect data about reproductive health and pregnancy, and a secret ballot box to obtain information related to abortion experiences.
Data were collected from 2,002 urban and literate Brazilian women aged 18-39 years, corresponding to 83% of the total female population.
Over half (56%) the women reported that they had avoided, or tried to avoid pregnancy because of the Zika virus.
Conversely, 27% of women reported that they had not tried to avoid pregnancy because of the epidemic and 16% had not been planning to get pregnant, regardless of the epidemic.
A higher proportion of northeastern women (66%) than southern women (46%) reported avoiding pregnancy, and the authors say this is most likely due to the epidemic being more concentrated in northeastern Brazil.
Black (64%) and brown (56%) women were more likely to report avoiding pregnancy than white women (51%), most probably reflecting the disproportionate impact of the epidemic on vulnerable racial groups, they add.
There were no significant differences among the main religious groups: 58% of Catholic women and 55% of Evangelic women reported having avoided pregnancy because of the Zika virus.
Brazil must urgently re-evaluate its reproductive health policies to ensure better access to contraception information and methods. This includes making available a wider range of contraceptive methods, including long-acting reversible contraception, which are either scarce, such as the copper intrauterine device, or not available, such as hormonal implants, through public health services.
