RESUMO
Trichomoniasis is the most prevalent sexually transmitted infection worldwide, and is associated with adverse pregnancy outcomes. However, Trichomonas vaginalis (TV) has received little public health attention, and only limited data are available on prevalence of TV and other Trichomonas-associated syndromes in pregnant women. This study aimed to determine associations between pregnancy and incident trichomoniasis-related diseases. Data of pregnant women were extracted from the National Health Insurance Research Database (NHIRD) of Taiwan. The pregnant cohort included 113,781 women, and cases were randomly matched by age, and index year with those of non-pregnant women (n = 113,781). Risk of incident trichomoniasis-related diseases was also not significantly different between pregnant and non-pregnant women. However, after stratifying by age or level of care, the younger subgroup among pregnant women had a higher risk of incident trichomoniasis-related diseases than did the younger subgroup in non-pregnant women, while the elder subgroup among pregnant women had a lower risk of incident trichomoniasis-related diseases than did the same subgroup in non-pregnant women (all p < 0.05). The higher level of care (medical center) subgroup among pregnant women had a lower risk of incident trichomoniasis-related diseases than did the same subgroup in non-pregnant women. In conclusions, although pregnancy is not significantly associated with risk of trichomoniasis-related diseases, data of the present study support an enhanced high level of medical care for pregnant women, emphasizing the potential of high medical care in reduced incidence of trichomoniasis-related diseases. This may be an effective strategy for reducing various pregnancy complications associated with trichomoniasis-related diseases.
