There are few studies on the comorbidity of hypertension (HTN), diabetes mellitus (DM) and dyslipidemia (DLP) associated with stroke. We aimed to explore the relationship between the number of metabolic diseases and stroke and its different subtypes, and to reveal whether metabolic diseases alone or coexist can significantly increase the risk of stroke. We completed a multi-center case-control study in Jiangxi Province, China. Neuroimaging examination was done in all cases. Controls were stroke-free adults recruited from the community in the case concentration area and matched with the cases in 1:1 ratio by age and sex. Odds ratios (OR) were calculated by conditional logistic regression. We enrolled 11,729 case-control pairs. The estimated ORs among patients with 1, 2 and 3 metabolic diseases were 3.16 (2.78-3.60), 7.11 (6.16-8.20), 12.22 (9.73-15.36), respectively after adjusting age, body mass index, urban-rural areas, cardiac disease, smoking, alcohol intake, physically active, high intake of salt, meat-biased diet, high homocysteine. The coexistence of HTN and DM (OR: 7.67), the coexistence of HTN and DLP (OR:7.58), and the coexistence of DM and DLP (OR:3.64) can all significantly increase the risk of stroke. HTN alone or combined other metabolic diseases were significantly more strongly associated with intracerebral haemorrhage than ischemic stroke. The risk of stroke increased with the number of chronic metabolic diseases. It is necessary to regularly monitor blood pressure, blood sugar and blood lipids and strengthen lifestyle management and take appropriate drug interventions to prevent exposure to multiple metabolic diseases based on existing conditions.
