Hurricane María and prenatal maternal mental health: Variations in stress, social support, and depression across disaster recovery periods in Puerto Rico.
Article in Environmental research, 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
Extreme weather events are increasingly associated with adverse mental health outcomes, but scarce research has examined these effects among pregnant populations. Pregnant women may be especially susceptible to psychological distress from disasters due to physiological demands of pregnancy and heightened sensitivity to environmental stressors. Using data from the PROTECT birth cohort in Puerto Rico, we assessed relationships between exposure to Hurricane María and assessments of perceived stress (PSS), depressive symptoms (CES-D), and social support (ESSI) among pregnant individuals at 28 ± 2 weeks gestation. Participants (n = 2231) were categorized into three groups based on study visit timing relative to Hurricane María: pre-hurricane (n = 1097), 0-6 months post-hurricane (n = 76), and >6 months post-hurricane (n = 906). Multivariable linear regression and interaction models were used to assess differences across time periods and sociodemographic strata. Perceived stress scores were 0.52 points higher (SE = 0.83, p = 0.52) 0-6 months post-hurricane, but 1.11 points lower (SE = 0.37, p < 0.01) >6 months post-hurricane compared to pre-hurricane levels. Depression scores were 0.61 points higher (SE = 1.04, p = 0.56) initially but -2.07 points lower (SE = 0.40, p < 0.01) in the later period. Social support scores remained similar initially (0.06 points, SE = 0.47, p = 0.91) with higher scores >6 months post-hurricane (0.63 points, SE = 0.17, p < 0.01). Significant differences in stress scores were observed by age, education, and income, with greater impacts among older and higher-income participants. However, lower symptom scores post-hurricane may reflect adaptation, selection bias, or measurement limitations rather than true improvements. Findings underscore the need for disaster response efforts that prioritize maternal mental health and address structural inequities in recovery.
