Biological Influences on Health-Ratings: The Relationship of Biomarkers and Self-Rated Health and How It Differs across Groups
This paper contributes to the state of research by analyzing data from the Canadian Health Measures Survey (CHMS). Additionally to a health questionnaire the CHMS comprises, among others, physical measures like grip strength, blood measures like infection markers, and urine measures like creatinine levels. With these data cross-sectional analyses are conducted in order to determine the relative contribution of different types of health information for several groups in explaining self-rated health and whether physical measures and biomarkers can contribute to this explanation beyond information typically collected in questionnaire-only health surveys. All in all, this research evaluates the relevance of collecting this information in explaining self-rated health and whether self-rated health is invariantly measured in different groups.
