Work status changes and associated factors in a nationwide sample of Norwegian long-term breast cancer survivors

Abstract

PurposeThe study aims to describe work status at diagnosis and 8 years post-diagnosis in a nationwide sample of breast cancer survivors (BCSs), and investigate associated and self-reported factors of reduced work status.MethodsWomen aged 20–65 years when diagnosed with stage I–III breast cancer (BC) in 2011 or 2012 were invited to participate in a questionnaire study in 2019 (n = 2803), of whom 49% (n = 1361) responded. For this sub-study, we included 974 BCSs below the legal retirement age in Norway (< 67 years) at survey and with complete work status data. Reduced work status was defined as being in paid work at BC diagnosis and not working at time of survey. Logistic regression analyses were applied to identify factors associated with reduced work status.ResultsOf BCSs who were in paid work at diagnosis (n = 845), 63% maintained their work status to 8 years later. Reduced work status was associated with not living with children (OR .44, 95% CI .24–.82), age (OR 1.16, 95% CI 1.11–1.21), chemotherapy (OR 2.83, 95% CI 1.24–6.61), > 2 comorbid conditions (OR 2.27, 95% CI 1.16–4.32), cognitive function (OR .99, 95% CI .98–.99), fatigue (OR 1.02, 95% CI 1.01–1.03), and neuroticism (OR 1.57, 95% CI 1.00–2.46). BC and late effects were reported as reasons for reduced work status and disability.ConclusionsThe majority of BCSs who were in paid work at diagnosis were working 8 years later.Implications for Cancer SurvivorsOur results suggest a need to focus on fatigue and reduced cognitive function among long-term BCSs, with the ultimate aim of improving work sustainability.
