Mental health and the healthy immigrant effect in Chile: a comparative cross-sectional study with international migrants and locals.
Observational study in Frontiers in public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Introduction: The question of whether international migrants appear to be in better health than the locals, and whether this "healthy immigrant effect" declines over time is a highly relevant one, especially with regards to mental health. Based on a community-based survey conducted in Santiago, Chile, this study compares the mental health outcomes of international migrants versus local populations and examines differences within the international migrant group of respondents. Methods: Observational cross-sectional study. Data was collected with international migrants and Chilean participants in 2021-2022 through a structured questionnaire. The study examined self-reported stress and mood disorders in relation to demographic, socioeconomic, health, and migration-related factors. Descriptive analyses were conducted for all variables overall and stratified by perceived stress, mood disorders, and migration status. Associations were assessed using Chi-square or Fisher's exact tests, with Cramer's V used to evaluate effect size. Multiple imputation (m = 5) addressed missing data using the mice package in R, followed by generalised logistic regression models fitted across imputed datasets and combined using Rubin's rules; stepwise selection based on AIC was used for variable reduction, and models were run for the full sample and separately for the migrant population. Results: The sample included 1,656 international migrants and 1,664 locals. Being a migrant was negatively associated with reporting stress and mood disorders in all analyses. Among migrants, the main risk factors for stress were perceiving a high number of migrants in the neighbourhood and having experienced abuse as a migrant and for mood disorders the main risk factor was reporting having experienced abuse as a migrant as well as a longer stay in Chile. Discussion: We found a healthy immigrant effect for mental health among international migrants in Chile, which declined over time in the case of mood disorders. Chilean participants reported very high levels of mental health issues, consistent with existing studies. However, results for international migrants highlight both risk and protective factors linked to migration processes, which are unique to them, warranting a specific approach to their mental health needs.
