A feasibility study exploring precarious employment and stress-related health among women.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundStress is a hypothesized mechanism through which precarious employment (PE) may contribute to poor health; however, there is a limited understanding of this potential mechanism in the U.S. This study aimed to (1) provide preliminary insights into the biological stress profiles of women experiencing varying levels of PE and (2) test the feasibility of at-home collection of stress biomarkers, c-reactive protein (CRP), and salivary cortisol, among women in Chicago, Illinois.
methodsWe recruited 101 working-age women between August-October 2023. An online survey collected information on demographics, PE, and self-reported mental (Center for Epidemiologic Studies Depression Scale, Cohen’s Perceived Stress Scale) and physical (self-reported health, body mass index) health. We mailed home-collection kits to collect capillary blood (120 𝜇L) and saliva (3 samples on 2 workdays). We used 27 employment indicators to construct a multidimensional PE score (PES) (range:0–10) and estimated descriptive statistics overall and by tertile of PE.
resultsWe reached our recruitment target of ~ 50 women/month, and 70% returned the test kits. The sample was diverse in age (18–40 years: 57%, 41–64 years: 43%) and education ([Formula: see text]highschool: 11%, some college: 29%, [Formula: see text]bachelor’s: 60%). Non-Hispanic (NH)-Black (33%) and Hispanic (36%) women were over-represented, compared to NH-White women (28%). More than half earned <$40,000, and the average PES was 3.6 (SE = 0.3). The most precariously employed women identified as NH-Black and Hispanic, had lower levels of educational attainment, experienced discrimination and had poorer self-reported physical and mental health. Those lost-to-follow-up between the online survey and biospecimen collection were lower-education, lower-income, more precariously employed, identified as Hispanic, and had poorer health. Biomarker patterns across PE tertiles were inconsistent; however, there was some suggestive evidence that the most precariously employed group may have lower recovery cortisol trends throughout the day, compared to the low and mid PE groups.
conclusionsWe demonstrate the feasibility of at-home data collection of biospecimen samples among working women. Larger studies of PE and health are warranted.
