Aging with burden: multimorbidity, depression and quality of life in older adults residing in long-term care facilities in South Africa.
Article in BMC geriatrics, 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
backgroundPopulation ageing has become an immediate global imperative, with older adults disproportionately afflicted by multimorbidity, a complex interplay of co-existing chronic diseases that erodes health-related quality of life (HRQoL). Multimorbidity is associated with impairments in physical and mental functioning, which undermine older adults' autonomy and contributes to declines in HRQoL. However, vital data that explore these relationships remain absent for older populations residing in long-term care facilities (LTCFs) across sub-Saharan Africa. This study examines multimorbidity prevalence in LTCF residing older adults and its associations with depression, HRQoL outcomes and physical activity.
methodsA cross-sectional study among 396 older adults from 17 randomly selected South African LTCFs employed the Geriatric Depression Scale, EQ-5D-3 L, and Weighted Functional Comorbidity Index. Descriptive statistics, correlation analyses and TwoStep cluster analysis elucidated multimorbidity patterns.
resultsMultimorbidity affected 76.77% of participants, with variation across four distinct clusters. The Cardiovascular-Respiratory cluster comprised 33.8% predominance. Multimorbidity was significantly predicted by poorer HRQoL and increasing age, χ²(140, n = 396) = 228.19, p < .001. Depression prevalence reached 35.10%, with higher scores associated with greater multimorbidity burden (ρ = 0.28, p < .01) and reduced HRQoL. An inverse correlation between the Weighted Functional Comorbidity Index and EQ-5D-3 L scores (ρ = -0.33, p < .001) reflected multimorbidity's negative impact on HRQoL. Multimorbidity was inversely associated with Short Physical Performance Battery scores, lower physical activity, and directly to waist-to-hip ratios.
conclusionAdvancing age is strongly associated with an increased burden of multimorbidity, which is intricately linked to depressive symptoms, diminished HRQoL, reduced muscular strength, central adiposity, and physical inactivity. These findings highlight the urgent need for integrated interventions in institutionalised older adults in sub-Saharan Africa and should inform policy reform aimed at strengthening long-term care and healthy ageing strategies.
