ABSTRACT
The aim of this study was to assess social and health status of residents older than 90 years in an East-Hungarian city. The investigation involved 70 subjects, measuring routine laboratory parameters and plasma viscosity. Mean cholesterol, erythrocyte sedimentation rate (ESR), collagen cross links and plasma viscosity values exceeded the reference range, but mean red blood cell count, hematocrit and hemoglobin were below it. Plasma viscosity was found pathologically elevated in 51% of cases. We compared these results with an earlier laboratory screening test performed on the same population with the age range of 60 to 90 years. In this cohort the mean fibrinogen concentration, ESR, HDL-cholesterol and collagen cross links values were higher, but mean cholesterol, triglyceride, total protein, hemoglobin and hematocrit values were lower than the reference range.
