Objectives: This study investigated mortality differentials between self-employed persons in Sweden, considering industrial sector, enterprise characteristics and socio-demographic factors.
Methods: Data on 321,274 self-employed persons were obtained from population registers in Sweden. Cox proportional hazards models were used to compare all-cause and cause-specific mortality rate ratios by industrial sector and enterprise legal form, adjusted for confounders.
Results: All-cause mortality was 10–32% higher in self-employed persons in Manufacturing and Mining, Trade and Communication, and Not Specified and Other sectors than in Agriculture, Forestry, and Fishing. Mortality from cardiovascular disease was 23% higher in Trade and Communication, and from neoplasms 17–51% higher in Manufacturing and Mining, Not Specified, and Other. Mortality from suicide was 45–60% lower in Personal and Cultural Services, and in Not Specified. Mortality was 8–16% higher in sole proprietorship than limited partnership.
Conclusions: Further research of working conditions is warranted, considering industry and enterprise legal form.
