The social context of poverty is consistently linked to Trichomonas vaginalis infection, yet few studies regarding T. vaginalis have been conducted exclusively among low-income individuals. We identified social determinants of health associated with prevalent T. vaginalis infection among homeless and unstably housed adult women.
Between April and October of 2010, we conducted cross-sectional T. vaginalis screening and behavioural interviews in an existing cohort of San Francisco homeless and unstably housed women. Data were analysed using multivariable logistical regression.
Among 245 study participants, the median age was 47 years and 72% were of non-Caucasian race/ethnicity. T. vaginalis prevalence was 12%, compared to 3% in the general population, and 33% of infected individuals reported no gynaecological symptoms. In adjusted analysis, the odds of T. vaginalis infection were lower among persons older than 47 years, the population median (OR=0.14, 95% CI 0.04 to 0.38), and higher among those reporting recent short-term homeless shelter stays (OR=5.36, 95% CI 1.57 to 18.26). Race and income did not reach levels of significance. Sensitivity analyses indicated that testing all women who report recent unprotected sex would identify more infections than testing those who report gynaecological symptoms (20/30 vs 10/30; p=0.01).
The prevalence of T. vaginalis is high among homeless and unstably housed adult women, over one-third of infected individuals have no gynaecological symptoms, and correlates of infection differ from those reported in the general population. Targeted screening and treatment among impoverished women reporting recent unprotected sex, particularly young impoverished women and all women experiencing short-term homelessness, may reduce complications related to this treatable infection.
This research output has an Altmetric Attention Score of 7. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 13 December 2017.
All research outputs
#5,743,133
of 26,875,495 outputs
Outputs from Sexually Transmitted Infections
#1,256
of 3,872 outputs
Outputs of similar age
#63,926
of 279,624 outputs
Outputs of similar age from Sexually Transmitted Infections
#32

Altmetric has tracked 26,875,495 research outputs across all sources so far. Compared to these this one has done well and is in the 78th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 3,872 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.6. This one has gotten more attention than average, scoring higher than 67% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 279,624 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 77% of its contemporaries.
We're also able to compare this research output to 90 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 64% of its contemporaries.
