Background: Prevalence studies are needed to assess the distribution of diseases. However, in a contrasting health promotion perspective, self-rated health is in itself an important field of study. This study investigated self-rated global health in the general population in Norway.
Methods: As part of a national survey, a two-item measure of global health (score range 0-100) was administered to a general population sample, and 1776 of 4961 eligible participants (response rate 36%) responded. Group comparisons were conducted using independent t-tests and one-way analyses of variance, whereas factors associated with global health was investigated with linear regression analysis.
Results: In the adjusted analyses, better global health was associated with higher age (β = 0.13, p < 0.001), having higher education (β = 0.10, p < 0.001), being employed (β = 0.21, p < 0.001), and living with a spouse or partner (β = 0.05, p < 0.05).
Conclusions: While global health was similar for men and women in the Norwegian general population, other sociodemographic variables were linked with global health. In particular, the link between employment and self-rated global health was strong. The findings are considered representative for the Norwegian population.
