Prevalence of anxiety disorders in Latin America: a systematic review and meta-analysis.
Article in Lancet regional health. Americas, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: The prevalence of anxiety disorders among the adult population in Latin America (LATAM) and its association with development indicators is insufficiently characterised. We estimated pooled regional, country, and sex-specific prevalence rates of anxiety disorders in LATAM based on International Classification of Diseases (ICD) or Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria. Additionally, we examined the association between its prevalence and four country-level development indicators: Human Development Index (HDI), income inequality (Gini coefficient), Gender Inequality Index (GII), and Intentional Homicide Rate (IHR). Methods: We conducted a systematic review and meta-analysis of population-based studies on the prevalence of ICD/DSM anxiety disorders in LATAM from 1990 to 2024, irrespective of language. We searched PubMed, PsycINFO, Cochrane Library, SciELO, LILACS, and grey literature. Study quality was assessed using JBI's critical appraisal tools. Pooled estimates were generated using random-effects meta-analysis, and heterogeneity was evaluated using the I-squared ( Findings: Using data from 36 studies in LATAM, we calculated the lifetime, 12-month, and current prevalence of ICD/DSM anxiety disorders at 14.55% (95% Confidence Interval 12.32%-17.11%; Interpretation: This study shows that approximately one in seven people in LATAM experience anxiety disorders at some point in their lives. These findings highlight the need to strengthen mental health systems in the region, and evidence the association between prevalence of anxiety disorders and development indicators. Our results can serve as a baseline for tracking anxiety disorders and for informed decision-making at the national and regional levels. The substantial heterogeneity between studies and the underrepresentation of some countries underscore the imperative for enhancing regional mental health capacities.
