Sarcopenia as a risk factor for incident pain in Chinese middle-aged and older adults: longitudinal evidence from the CHARLS cohort.
Article in The journal of nutrition, health & aging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesThis study aimed to prospectively examine sarcopenia as a risk factor for incident pain in middle-aged and older Chinese adults, analyze independent associations between subcomponents of sarcopenia (low muscle mass, handgrip strength, and physical performance) and incident pain, and evaluate subgroup specificities.
designProspective cohort study.
settingNationwide, using data from the China Health and Retirement Longitudinal Study (CHARLS) waves 2011, 2013, and 2015.
participants3,148 adults aged 45 years and older without pain at baseline. MEASUREMENTS: Sarcopenia was defined per AWGS 2019 criteria, incorporating appendicular skeletal muscle mass (ASM), handgrip strength, and physical performance (gait speed and chair stand test). Incident pain was assessed using standardized self-reported questions from the CHARLS questionnaire. Cox proportional hazards models estimated hazard ratios (HR) and 95% confidence intervals (CI), adjusted for age, sex, residence, marital status, education, smoking, alcohol consumption, hypertension, diabetes, stroke, heart disease and depression. Restricted cubic splines (RCS) explored exposure-response relationships, and subgroup analyses assessed interactions.
resultsPain incidence was 35.93%, possible sarcopenia 60.23%, and sarcopenia 34.37%. Sarcopenia was associated with a 52% higher hazard of incident pain (fully adjusted HR = 1.52, 95% CI: 1.10-2.10, p = 0.011). For the subcomponents of sarcopenia, only low muscle mass showed a positive association with incident pain risk in the fully adjusted model (HR = 1.21, 95% CI: 1.06-1.38, p = 0.005). Subgroup analyses showed that sarcopenia status interacted with education status and depression (both P for interaction <0.001).
conclusionSarcopenia independently predicts incident pain in aging Chinese populations, highlighting the need for early musculoskeletal health interventions, such as nutrition and exercise, to reduce pain burden and support healthy aging.
