Work productivity and activity impairment in patients with primary Sjögren's syndrome.

Objectives: In this observational, analytical, cross-sectional study we aimed to describe the impact of primary Sjögren's syndrome (pSS) on work productivity and activities of daily living (ADL) to assess the association between ADL impairment and clinical manifestations and to compare ADL impairment according to patients' socioeconomic condition.

Methods: Patients diagnosed with pSS attending 11 centres from Argentina were included. To evaluate work productivity and ADL impairment, a work productivity and activity impairment questionnaire (WPAI) was used.
