Catch-up saccades (CUS) are corrective eye movements indicating vestibulo-ocular reflex (VOR) impairment. Although video head impulse testing (vHIT)enables objective detection of CUS, data on its prevalence and correlations in the general population are limited. This study analyzed 1,982 Korean adults aged ≥40 years from the 2021 KNHANES. CUS was identified via vHIT. Logistic regression was used to examine factors associated with CUS, including sex-stratified models. The overall prevalence of CUS was 16.2%, increasing with age from 12.8% in the 40s to 40.2% in those aged ≥80. Older age was the strongest correlate of CUS (OR for ≥80 vs 40s: 6.15, 95% CI: 2.62–14.43). Lower educational attainment was inversely associated with CUS prevalence, particularly in women. Among men, former smoking was inversely associated with CUS (OR: 0.50, 95% CI: 0.31–0.81). CUS are common in older Korean adults and exhibit distinct sociodemographic patterns by sex. These findings suggest that vHIT-detected CUS may be useful as a practical screening tool for identifying early vestibular decline, particularly in socioeconomically vulnerable groups. Public health efforts aimed at early detection and fall prevention should consider sex- and SES-specific risk factors.
