Background: The epidemiological relationship of vitiligo with systemic sclerosis (SSc) remains to be precisely evaluated. Objective: To investigate the bidirectional association between vitiligo and SSc. Methods: A population-based study was carried out to compare vitiligo patients (n = 20,851) with age-, sex- and ethnicity-matched control subjects (n = 102,475) regarding the incidence of new-onset and the prevalence of preexisting SSc. Adjusted hazard ratios (HRs) and adjusted odds ratios (ORs) were calculated by the Cox regression and logistic regression, respectively. Results: The incidence rate of new-onset SSc was calculated at 2.4 (95% CI, 1.6–3.4) and 0.4 (95% CI, 0.3–0.6) cases per 10,000 person-years among patients with vitiligo and controls, respectively. Patients with vitiligo had an increased risk of SSc (fully adjusted HR, 5.37; 95% CI, 3.03–9.54; p < 0.001). Correspondingly, a history of SSc predicted elevated odds of developing vitiligo (fully adjusted OR, 2.09; 95% CI, 1.23–3.55; p = 0.006). Relative to other patients with vitiligo, those with vitiligo and comorbid SSc were older and had a higher prevalence of ischaemic heart disease, hyperlipidaemia, and hypertension. Conclusions: A robust bidirectional association exists between vitiligo and SSc. This knowledge is valuable for physicians managing patients with both conditions. Patients with vitiligo and comorbid SSc might be monitored for cardiovascular and metabolic comorbidities.
