Association between red blood cell folate and Trichomonas vaginalis infection among women.

ABSTRACT:

Background

Increased folic acid has been found to be latently protective against gynecological infection, including several kinds of vaginosis. In this study, we laid emphasis on whether RBC (Red Blood Cell) folate was associated with the infectious ratio of Trichomonas vaginalis, a kind of anaerobic parasitic protozoan.

Methods

We set RBC folate as the exposure variable and Trichomonas vaginalis as the outcome variable. Other subsidiary variables were regarded as covariates that may work as potential effect modifiers. The cross-sectional study was conducted with two merged waves of the National Health and Nutrition Examination Survey (NHANES) from 2001 to 2004, and a sample of 1274 eligible women (1212 negative and 62 positive in Trichomonas vaginalis infection) was integrated for the exploration of the association between RBC folate and Trichomonas vaginalis infection. Multivariate regression analyses, subgroup analyses, and subsequent smooth curve fittings were conducted to estimate the relationship between RBC folate and Trichomonas vaginalis in women.

Results

In the multivariable logistic regression analyses, a negative association was observed between stratified RBC folate status and Trichomonas vaginalis infection with all confounders adjusted. Referencing the lowest RBC folate concentration quartile, the higher concentration quartiles reported a relatively lower infection ratio, while there was a weak correlation between total RBC folate concentration and T. vaginalis (Trichomonas vaginalis) infection. In subgroup analyses stratified by BMI and age, this association was only found significant in high age and BMI groups.

Conclusions

The cross-sectional study indicated a negative association between RBC folic acid and Trichomonas vaginalis infection, and latent effects of BMI and age on the association were also found.

Project description:BackgroundTrichomoniasis is the most prevalent nonviral sexually transmitted infection in the United States. Numerous studies have shown disproportionately higher prevalence rates in non-Hispanic Black women. Because of the high rates of reinfection, the Centers for Disease Control and Prevention recommends retesting women treated for trichomoniasis. Despite these national guidelines, there are few studies examining adherence to retesting recommendations for patients with trichomoniasis. Adherence to retesting guidelines has been shown in other infections to be an important determinant of racial disparities.ObjectiveThis study aimed to describe Trichomonas vaginalis infection rates, evaluate adherence to retesting guidelines, and examine characteristics of women who were not retested according to the guidelines in an urban, diverse, hospital-based obstetrics and gynecology clinic population.Study designWe conducted a retrospective cohort study of patients from a single hospital-based obstetrics and gynecology clinic who were tested for Trichomonas vaginalis between January 1, 2015 and December 31, 2019. Descriptive statistics were used to examine guideline-concordant testing for reinfection among patients with trichomoniasis. Multivariable logistic regression was used to identify characteristics associated with testing positive and with appropriate retesting. Subgroup analyses were performed for patients who were pregnant and tested positive for Trichomonas vaginalis.ResultsAmong the 8809 patients tested for Trichomonas vaginalis, 799 (9.1%) tested positive at least once during the study. Factors associated with trichomoniasis included identifying as non-Hispanic Black (adjusted odds ratio, 3.13; 95% confidence interval, 2.52-3.89), current or former tobacco smoking (adjusted odds ratio, 2.27; 95% confidence interval, 1.94-2.65), and single marital status (adjusted odds ratio, 1.96; 95% confidence interval, 1.51-2.56). Similar associated factors were found in the pregnant subgroup analysis. For women with trichomoniasis, guideline-concordant retesting rates were low across the entire population, with only 27% (214/799) of patients retested within the recommended time frame; 42% (82/194) of the pregnant subgroup underwent guideline-concordant retesting. Non-Hispanic Black women had significantly lower odds of undergoing guideline-recommended retesting than non-Hispanic White women (adjusted odds ratio, 0.54; 95% confidence interval, 0.31-0.92). Among patients tested according to guideline recommendations, we found a high rate of Trichomonas vaginalis positivity at retesting: 24% in the entire cohort (51/214) and 33% in the pregnant subgroup (27/82).ConclusionTrichomonas vaginalis infection was identified at a high frequency in a diverse, urban hospital-based obstetrics and gynecology clinic population. Opportunities exist to improve on equitable and guideline-concordant retesting of patients with trichomoniasis.
