Association of unhealthy lifestyle and the risk of type 2 diabetes mellitus with arthritis in middle-aged and elderly Chinese individuals: evidence from the CHARLS.
Article in Aging clinical and experimental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundMultimorbidity is an emerging global public health concern. However, the relationship between a healthy lifestyle, type 2 diabetes mellitus (T2DM) and arthritis remains unclear. Our study aimed to evaluate the impact of a healthy lifestyle on the comorbidity of T2DM and arthritis in the Chinese population.
methodsThe data originated from the China Health and Retirement Longitudinal Study (CHARLS) and comprised 4,706 participants aged 45 years or over. The healthy lifestyle score (0-5) was determined by factors including smoking, drinking, physical activity, sleep and body mass index (BMI). T2DM was assessed using a self-reported physician diagnosis, fasting blood glucose levels ≥ 7.0 mmol/L, or a history of taking hypoglycaemic medication. Arthritis was evaluated using a self-reported physician diagnosis at baseline. Multivariate logistic regression models and stratified analyses were used to estimate the relationship between healthy lifestyles and the risk of T2DM in patients with arthritis. Receiver operating characteristic (ROC) curves were analysed to investigate the association between an unhealthy lifestyle, T2DM and arthritis risk.
resultsCompared with healthy lifestyle participants, those with unhealthy lifestyles had an increased risk of diabetes (OR = 1.41, 95% CI: 1.01-1.95) and comorbid diabetes‒arthritis (OR = 1.73, 95% CI: 1.01-2.96), but no significant associations with arthritis were detected. In the stratified analysis, stronger associations were found between an unhealthy lifestyle and diabetes-arthritis comorbidity in people aged 45-65 years and in those who were married. ROC analysis revealed high diagnostic accuracy of unhealthy lifestyle for both diabetes (AUC = 0.894) and diabetes-arthritis comorbidity (AUC = 0.894).
conclusionAn unhealthy lifestyle was significantly associated with diabetes-arthritis comorbidity among participants ≥ 45 years of age in China, which suggesting that promoting healthy lifestyle may be important for reducing the burden of chronic disease.
