SNHL was defined as an average pure-tone threshold of ≥20 dB in at least one better ear.
SNHL was defined as an average pure-tone threshold of ≥20 dB in at least one better ear. Stroke prevalence was 1.6% in SNHL participants versus 0.4% in those without SNHL. Stroke was associated with SNHL in univariable regression (OR = 3.67, 95% CI: 1.12–12.00) and remained significant after adjustment (OR = 4.22, 95% CI: 1.28–13.93). Cardiovascular risk score was positively correlated with SNHL in multivariable models (OR = 1.66, 95% CI: 1.40–1.96) but did not remain significant with all covariates adjusted. Age and sex were identified as the more direct independent risk factors for SNHL. The cross-sectional design limits causal inference, and the relatively small sample size and partial NHANES data may affect generalizability.
