Association of body mass index with disability in activities of daily living in older adults: a systematic review of the literature based on longitudinal data.
Synthesis in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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 influence of Body Mass Index (BMI) on the functional capacity for daily activities in older adults is a significant concern. Our study is designed to delineate the longitudinal relationship between BMI and the ability of daily living activities among older adults.
methodsTwo researchers conducted a comprehensive literature search and independent screening of articles in PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), the Database for Chinese Technical Periodicals (VIP), and Wanfang, covering the period from January 2000 to May 2024. Studies were selected based on predefined inclusion and exclusion criteria, and relevant data were extracted for subsequent meta-analysis using the Cochrane Collaboration's Review Manager 5.3 software.
resultsAfter rigorous selection, four longitudinal studies were incorporated into our meta-analysis. The findings indicated that underweight older adults exhibited a higher likelihood of experiencing difficulties with basic activities of daily living (BADL) (odds ratio [OR] = 1.33, 95% confidence interval [CI]: [1.03, 1.72]; P = 0.03). Conversely, overweight older adults were found to have a reduced likelihood of BADL (odds ratio [OR] = 0.81, 95% confidence interval [CI]: [0.79, 0.83]; P < 0.001). However, overweight and obese older adults demonstrated an increased likelihood of challenges with Instrumental Activities of Daily Living (IADL) (odds ratio [OR] = 1.58, 95% confidence interval [CI]: [1.25, 2.00]; P < 0.01).
conclusionsOur longitudinal meta-analysis substantiates the correlation between underweight status and the impairment of BADL in older adults, irrespective of gender. It also reveals that overweight older adults have a lower risk of BADL difficulties, yet a higher risk of IADL challenges, which is further exacerbated in obesity. The early identification and management of BMI in this population could be instrumental in preventing a decline in ADL. Recognizing the role of BMI categories in this context is essential for developing targeted preventative strategies for the elderly, while also accounting for other modifiable risk factors such as pain and depression.
