Resumo

Background Composition of the vaginal microbiome is strongly related to a woman's reproductive health and risk of sexually transmitted infections. Ethnoracial, behavioral, and environmental factors can influence microbiome. The Brazilian population is unique in terms of miscegenation of ethnic groups and behavioral characteristics across different regions. We aimed to characterize the vaginal microbiome of women from 5 geographical regions of Brazil. Methods We sequenced V3-V4 regions of 16S rRNA gene in vaginal samples of 609 reproductive-aged women. We performed logistic regression analyses to estimate odds ratios (OR) and 95% confidence intervals (CI) for the association between sociodemographic and behavioral factors withLactobacillus-depleted microbiome (community state type {[}CST] IV). Results Vaginal samples were grouped into 5 CST: CST I (L. crispatuspredominant, 30.5%), CST II (L. gasseripredominant, 4.4%), CST III (Lactobacillus inerspredominant, 36.5%), CST IV (Lactobacillus-depleted, 27.4%), and CST V (L. jenseniipredominant, 1.2%). Several factors were independently associated with CST IV, such as smoking (OR, 1.80; 95% CI, 1.02-3.18), number of partners (OR, 2.11; 95% CI, 1.20-3.70), and vaginal douching (OR, 2.24; 95% CI, 1.34-3.74). A protective effect was observed for milk/dairy intake (OR, 0.47; 95% CI, 0.27-0.82) and sitz bathing (OR, 0.43; 95% CI, 0.19-0.98). Conclusions Nearly two thirds of Brazilian women may be at an increased risk for adverse outcomes associated with a vaginal microbiota characterized by the depletion ofLactobacillusor dominance byL. iners,whose protective role has been widely questioned. Several factors related to sexual behavior and intimate hygiene were associated with CST IV. (AU)
