Learning the hard way: What COVID-19 teaches us about the social determinants of mental health among the urban poor.
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
backgroundThe COVID-19 health crisis rapidly escalated into a broader social and economic emergency, affecting physical and mental health beyond the disease itself and placing a disproportionate burden on vulnerable populations. This study investigates the determinants of poor mental health related to COVID-19 among urban-poor homemakers residing in a social housing villa located on the outskirts of Santiago de Chile, a metropolitan city characterized by pronounced sociospatial segregation.
methodsCapitalizing on the ongoing RUCAS cohort study, we introduced a COVID-19 module into the biannual RUCAS survey to assess the associations between COVID-19-related social determinants of poor mental health and symptoms of depression during and after the 2020 lockdown among 413 homemakers. We describe the prevalence and distribution of COVID-19-related social determinants of poor mental health, and longitudinally examine their associations with depressive symptoms, measured using the Patient Health Questionnaire-2 (PHQ-2). Modified Poisson regression models were used to estimate prevalence ratios (PRs) and their corresponding 95% confidence intervals, including an interaction between the independent variable and the measurement wave for the longitudinal assessment.
resultsDuring lockdown, symptoms of depression among homemakers were most strongly associated with students in the household facing difficulties in completing schoolwork during homeschooling (PR: 2.62; 1.60–4.30). After lockdown, the strongest associations were observed with employment (being out of the labor force (PR: 1.59; 1.04–2.44); receiving reduced income from work (PR: 1.95; 1.22–3.11)), and the financial situation of the household: indebtedness (wave 4: acquisition of new debts, PR: 1.48; 1.04–2.11; wave 5: low debt-payment capacity, PR: 1.44; 1.01–2.07), and food insecurity (wave 4, PR: 1.92; 1.38–2.65; wave 5, PR: 1.59; 1.12–2.26). Household conflicts over space were associated with depressive symptoms in both waves (wave 4, PR: 1.43; 1.01–2.02; wave 5, PR: 1.74; 1.23–2.46). No association was found with being or living with a COVID-19 case.
conclusionsIn addition to the central role of financial stressors in shaping mental health outcomes during the COVID-19 pandemic, our results underscore the importance of home-schooling challenges as a critical source of psychological distress among peripheralized homemakers. These findings offer valuable insights for enhancing multisectoral preparedness in future crises, emphasizing the need to integrate social, economic, and educational support strategies for peripheralized urban-poor populations and to prevent or mitigate the deepening of existing social inequalities.
