| Summary: | Objective: To assess work productivity, identify associated factors and evaluate the economic burden of systemic sclerosis (SSc) in a multiethnic Asian population. Methods: Data on employment status and work productivity loss were collected. Associations between demographic and disease characteristics and unemployment status, work productivity loss, and activity impairment were examined using logistic and linear regression analyses, as appropriate. Costs of unemployment and work productivity loss were estimated using the human capital approach. Results: Of 111 patients with a mean disease duration of 9.1 years, 33 (29.7%) were unemployed. Their mean age at unemployment was 44.2 years, equating to 22.8 years of lost employment. No demographic and disease characteristics were significantly associated with unemployment status in multivariable analysis. Of 73 employed patients, 39 (53.4%) reported work productivity loss, accounting for 45.9% of the working week. The presence of hyperlipidemia (coefficient –19.01, P = 0.03) was associated with work productivity loss in multivariable analysis. In total, 37 of 78 employed patients (47.4%) and 19 of 33 unemployed patients (57.6%) reported activity impairment, accounting for 42.2% and 50.0%, respectively, of the preceding week. The presence of hyperlipidemia (coefficient –18.56, P < 0.01) was associated with activity impairment in multivariable analysis. Annual cost of unemployment and work productivity loss were estimated to be
