Abstract:ObjectiveStroke is a major cause of cardiovascular mortality and may have a correlative relationship with insulin resistance. To investigate the relationship between the metabolic score for insulin resistance (METS-IR) and new-onset stroke in middle-aged and elderly people based on a large cohort study.MethodsData were obtained from the China Health and Retirement Longitudinal Study (CHARLS) in 2011 and 2018. Regression models were developed to explore the association between METS-IR and new-onset stroke, while restricted cubic spline models were used to examine possible nonlinear associations and subgroup analyses were used to explore possible potential moderating variables.ResultsA total of 6706 study subjects were included in the study, including 381 with new-onset stroke. The regression model results found a 67.3% increase in the risk of new-onset stroke for each quartile increase in the METS-IR (OR=1.673, 95% CI: 1.440-1.944). A linear relationship between the METS-IR and the prevalence of new-onset stroke was shown using restricted three-sample regression analysis, and stratified analysis revealed that the relationship between METS-IR and new-onset stroke was consistent across subgroups.ConclusionThe METS-IR is strongly associated with the prevalence of new-onset stroke, and people with high METS-IR need to be more alert to the risk of stroke.
