摘要

Objectives

To investigate the association of metabolic status newly defined or obesity with asymptomatic intracranial arterial stenosis (aICAS) among populations in rural China.

Methods

The cross-sectional study is based on the Rose asymptomatic IntraCranial Artery Stenosis (RICAS) cohort, which enrolled 2005 participants aged 40 years or older without a history of clinical stroke or transient ischemic attack. Metabolically healthy status (MH) was defined by a newly proposed criterion: (1) systolic blood pressure (SBP) < 130 mmHg and without antihypertensive medication; (2) a waist-to-hip ratio (WHR) below 1.03 for men and below 0.95 for women; (3) no diabetes. All participants were categorized based on their metabolic status and obesity. Multivariate logistic regression models were used to investigate the association between metabolic status or obesity and aICAS.

Results

Among 2005 participants, 1597 (79.65%) were defined as metabolically unhealthy status (MU) according to the new criterion. MU was significantly associated with aICAS (OR 2.02, 95% CI 1.11–3.68, P = 0.021), especially moderate-to-severe aICAS (OR 2.43, 95% CI 1.04–5.72, P = 0.042). The prevalence of aICAS increased with the numbers of metabolic disorders (P for linear trend <0.001). Both metabolically unhealthy normal-weight (MUN) (OR 2.11, 95% CI 1.10–4.03, P = 0.025) and metabolically unhealthy obesity (MUO) (OR 3.30, 95% CI 1.64–6.64, P = 0.001) were significantly correlated with aICAS, but not metabolically healthy obesity (MHO). Subgroup analysis further confirmed the association between MU and aICAS risk only in men (P for interaction = 0.042).

Conclusions

MU defined by the new criterion was significantly associated with aICAS, especially with moderate-to-severe aICAS. This novel criterion effectively identifies individuals with a high prevalence of aICAS among populations with obesity, which could be crucial for stroke prevention.
