Prevalence and influencing factors of dementia in the elderly iranian population: a cross-sectional study.
Article in Aging clinical and experimental research, 2025. 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 global rise in dementia prevalence, a major neurocognitive disorder, poses a significant challenge to aging populations. This study aimed to determine the prevalence of dementia and its associated risk factors among community-dwelling elderly in selected provinces of Iran.
methodsA cross-sectional study was conducted from October 2022 to March 2024, enrolling 58,228 individuals aged 60-75 years from two provinces (Qazvin and Yazd) selected via multi-stage, stratified random sampling. A multi-stage diagnostic protocol was employed, using validated Persian versions of the Geriatric Depression Scale (GDS), Abbreviated Mental Test Score (AMTS), Mini-Mental State Examination (MMSE), Functional Assessment Staging (FAST), and Montreal Cognitive Assessment (MoCA) with standardized cut-offs. Multivariable logistic regression was used to identify factors associated with dementia.
resultsAfter exclusions, the final analytical sample was 56,456 participants. The overall prevalence of dementia was 10.1%. Prevalence was significantly higher in women (13.2%) than in men (7.0%). In the adjusted model, female gender (aOR: 2.04, 95% CI: 1.92-2.15), older age (70-79 years vs. 60-64 years, aOR: 1.70, 95% CI: 1.59-1.82), widowhood (aOR: 1.50, 95% CI: 1.05-2.16), and lower educational attainment (illiterate vs. academic, aOR: 6.55, 95% CI: 5.43-7.91) were significantly associated with higher odds of dementia.
conclusionsThis large-scale study reveals a substantial burden of dementia in the studied Iranian provinces. The identified risk factors, including female sex, advanced age, widowhood, and low education, highlight vulnerable subgroups and underscore the urgent need for targeted public health strategies focused on early detection, risk reduction, and support systems for the elderly in Iran.
