Objective We aimed at identifying differences regarding cognition, depressive symptoms and health-related quality of life between members of private and statutory health insurance (SHI) in very old age in Germany. Methods Cross-sectional data were gathered from the multicenter prospective "Study on Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)" (AgeQualiDe), covering primary care patients aged ≥ 85 years (n = 854; with 773 members of SHI). The Global Deterioration Scale measured cognition, the Geriatric Depression Scale assessed depressive symptoms, and health-related quality of life was measured by using a Visual Analogue Scale (EQ-VAS). Results While members of private health insurance showed slightly better cognitive function, less depressive symptoms and better health-related quality of life descriptively, regression models showed that none of these differences was statistically significant. Conclusions There are no differences between members of private health insurance and SHI regarding cognitive function, depressive symptoms and health-related quality of life in very old age.
