Obesity and Transition to Assisted Living Services in Older Adults: An Analysis From the National Health and Aging Trends Study.
Article in Journal of the American Geriatrics Society, 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 prevalence of obesity in older adults is increasing. Though body mass index (BMI) is often used as a measure of obesity, waist circumference (WC) may be a better reflection of obesity in older adults. While many factors contribute to transitioning to assisted living services (TALS), the relationship between obesity and TALS has demonstrated inconsistent results. This study aims to further understand the relationship between these anthropometric measures and incident TALS.
methodsThis analysis is based on longitudinal data from the National Health and Aging Trends Study (NHATS). Obesity was defined as BMI ≥ 30 kg/m
resultsThe resultant analytic cohorts included n = 11,111 and n = 10,374 participants with BMI and WC data, respectively. Rates of TALS were 25.7% in the entire study cohort: 24.9% in the BMI and 23.9% in the WC cohort. Using BMI, adjusted risk of TALS was HR 1.31 (95% CI: 0.95-1.79) for underweight, HR 0.74 (0.65-0.85) for overweight, HR 0.71 (0.59-0.85) for class 1 obesity, HR 0.58 (0.42-0.80) for those with class 2 obesity, and HR 0.69 (0.44-1.08) for those with class 3 obesity or higher. With elevated WC, TALS risk was HR 0.98 (0.86-1.12).
conclusionsOverweight, class 1, and class 2 obesity using BMI criteria were protective against TALS. Further study is needed to elucidate the underlying reasons for this protective effect against TALS.
