BACKGROUND: Insulin Resistance (IR) is associated with stroke. This study aimed to investigate the correlation between metabolic score for insulin resistance (METS-IR) level, a new biomarker for assessing IR, and stroke.
METHODS: This is a cross-sectional study based on data from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2020 and included participants aged ≥ 20 years. All participants provided complete stroke and METS-IR related data. The study employed statistical techniques, including multivariate logistic regression analysis, restricted cubic splines (RCS), and stratified analyses to evaluate the relationship between the amounts of METS-IR and the risk of stroke.
RESULTS: The study included 14,029 participants aged 20 years or older. The fully adjusted model revealed a statistically significant correlation between METS-IR and stroke (OR=1.21, 95% CI: 1.00, 1.46; P<0.05). Specifically, for every 10-unit increase in METS-IR, there was a 21% increase in the prevalence of stroke. The prevalence of stroke was 60% higher in the Q4 group compared to the Q1 group, as indicated by a significant association with METS-IR (OR=1.60, 95% CI: 1.01, 2.54; P<0.05). The RCS analysis revealed a strong linear correlation between METS-IR and the incidence of stroke (P<0.05). Subgroup analyses showed that gender, age, race, alcohol consumption, smoking, diabetes, and hypertension exhibited correlation with this positive association, and a significant interaction was observed in age (P for interaction < 0.05).
CONCLUSIONS: The findings of this study indicate that elevated METS-IR levels are strongly linked to a greater risk of stroke in adults.
