Cross-sectional observational study on prevalence and pattern of multimorbidity and its impact on geriatric outpatients in a south Indian tertiary hospital.

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 global aging population is increasing rapidly, with a significant rise anticipated in individuals aged 60 years and above over the coming decades. This demographic transition is expected to amplify the burden of chronic diseases and multimorbidity, especially in low- and middle-income countries like India. Methods: This observational cross-sectional study was conducted from November 2022 to November 2024 at a tertiary care hospital in South India. A total of 541 older adults (mean age 71.56 ± 7.06 years; 280 men and 261 women) attending a geriatric outpatient clinic were enrolled. A Comprehensive Geriatric Assessment (CGA) was performed to capture socio-demographic, lifestyle, and health-related variables. Hierarchical cluster analysis was utilized to identify patterns of multimorbidity and associated factors. Results: Among 541 participants, 66.17% had multimorbidity, defined as the presence of two or more chronic conditions, with a mean of 2.39 ± 1.71 chronic conditions per participant. Hypertension and type 2 diabetes mellitus were the most prevalent conditions, while malignant diseases were observed in only a small proportion of participants. Polypharmacy was observed in 13.9% of the study population and was significantly more frequent among men. Hierarchical cluster analysis identified two major multimorbidity clusters, one characterized predominantly by cardiometabolic and degenerative conditions and another associated with sociodemographic and lifestyle factors. Statistically significant associations were observed between multimorbidity and age, sex, education, income, and dietary patterns. Conclusion: This study highlights a high burden of multimorbidity among geriatric outpatients in South India, with hypertension and diabetes being the most prevalent. Clear gender-specific patterns and strong associations with socio-demographic and dietary factors were identified. The findings underscore the importance of individualized, gender-sensitive, and nutrition-focused strategies in the management of multimorbidity among older adults.
