Previous sickness presence among long‐term sick‐listed in Norway and Sweden: A retrospective study of prevalence and self‐reported reasons

The aim of the present study was to analyse previous sickness presence among long‐term sick‐listed individuals in Norway and Sweden and the reasons given for sickness presence. The study was based on survey data for 3,312 persons in Norway and Sweden who had been sick‐listed for at least 30 days. Two questions were used. One measured prevalence: During the last 12 months prior to your current sick leave, did you go to work even when feeling so ill that you should have taken sick leave? The second question concerned reasons for sickness presence. Large differences were found between Norway and Sweden in the prevalence of sickness presence. More long‐term sick‐listed Norwegians than Swedes reported sickness presence [adjusted odds ratio (OR) for Sweden 0.65 (0.53–0.80)]. The Swedes more often reported financial reasons for sickness presence [adjusted OR 2.77 (2.1 to ?3.54)], while the Norwegians more often gave positive reasons related to work. The national differences may be related to differences in sickness insurance strategies.
