Labour and non-labour market productivity in Chinese patients with systemic lupus erythematosus

Objectives. A cross-sectional study was performed to assess the self-reported loss of labour and non-labour market productivity, as well as to characterize the risk factors of loss of productivity in patients with SLE. Methods. A consecutive sample of 125 Chinese patients with a diagnosis of SLE and within working age was recruited. Work disability, daily activity limitations and receipt of social help, along with demographic information and health status, were collected from a self-reported questionnaire. Disease characteristics were collected by clinical examination and chart review. Univariate and multivariate logistic analyses were used to describe the relationships between labour/non-labour productivity and demographic/clinical variables. Results. Twenty (16%) patients reported complete work disability as a result of SLE after a median duration of 9 years since disease onset. A total of 46 (36.8%) patients reported difficulty in performing their daily activities, including household work, studying and leisure activities, among which 28% received social help from families or friends. Risk of work disability was strongly predicted by low education level, long disease duration and history of having pleurisy. Patients' global well-being, physical health status and functional status were factors independently associated with impaired non-labour market productivity. Conclusions. SLE has a profound impact on individuals' labour and non-labour market productivity. Vocational education programmes may be useful in lowering the work disability rate in SLE. Preserving patients' physical and mental functioning or improving patients' quality of life may help in restoring both labour and non-labour productivity.
