SDH were assessed at diagnosis and included education, income, marital status, work ability, unemployment and immigration status. Outcomes were organ damage (measured using the Lupus Register-Based Organ Damage Index) and all-cause mortality. Cox proportional hazards models estimated HRs, adjusting for age, sex and morbidity. Sensitivity analyses included SDH measured 2 years prior to diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>During follow-up, a total of 1044 (42.4%) newly diagnosed patients with SLE developed organ damage and 140 (6%) died. There was an increased risk of organ damage associated with sick leave or disability (HR: 1.44; 95%\u2009CI 1.27 to 1.64), lower income (HR: 1.33; 95%\u2009CI 1.09 to 1.63), being divorced or widowed (HR: 1.30; 95%\u2009CI 1.10 to 1.54) at diagnosis. The same SDH were also associated with mortality, as was lower education level (HR: 1.67; 95%\u2009CI 1.05 to 2.66). Immigration status and unemployment did not associate with organ damage or mortality. Results were similar when examining SDH measured 2 years prior to diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In this population-based SLE cohort, lower education, lower income, being divorced, widowed or single and reduced work ability were independently associated with increased risk of organ damage and mortality.
