Prevalence of syphilis and related risk behaviors among women in 5 distinct indigenous populations in Paraguay
ResumBackground The objective of this study was to measure the prevalence of syphilis among women of reproductive age from 5 distinct indigenous populations in Paraguay. We also sought to identify the demographic profile and behaviors of women with elevated prevalence of syphilis. Methods We conducted a population-based, cross-sectional survey among women aged 15 to 49 years from 5 distinct language families in Paraguay in 2016. The 5 language families were Guaraní, Maskoy, Mataco, Guaicurú, and Zamuco, sampled through a probability-based, multistage cluster design. Participants completed a questionnaire on demographic characteristics and risk-related behavior. Blood samples were drawn for rapid testing for syphilis with confirmation and titers. Participants provided written informed consent; minors had written parental consent and provided their own assent. Results A total of 1732 indigenous women were enrolled. Overall syphilis prevalence was 6.8% (95% confidence interval [CI], 5.6–8.0). Syphilis prevalence varied by language family/ethnic group (P = 0.010), with Mataco having the highest prevalence (8.2%; 95% CI, 5.3–11.9) and Maskoy having the lowest (2.5%; 95% CI, 1.1–4.7). Women reporting multiple partners (11.3%; 95% CI, 6.9–17.1; P = 0.031) and transactional sex in the last year (18.7%; 95% CI, 7.2–36.4; P = 0.010) had higher prevalence of syphilis. Conclusions Our survey found high prevalence of syphilis in indigenous women in Paraguay, in association with transactional sex and multiple partners. Interventions to reduce sexual behaviors associated with an increased risk of sexually transmitted infections (STI) in indigenous women must be carried out with programs aimed at addressing transactional sex, appropriately framed to respect interculturality and an indigenous worldview.
