To investigate the health-related quality of life (QOL) in Swedish patients with post-polio syndrome (PPS), with a focus on sex and age. A total of 364 patients were recruited from five Swedish post-polio clinics. Analysis was carried out using SF-36 and data were compared with those of a normal population. QOL was significantly lower in PPS patients for all eight subdomains and the two main scores (physical compound score and mental compound score) when compared with the controls. Male patients had a significantly higher QOL than female patients for all subdomains and also for mental compound score and physical compound score, a phenomenon also observed in the normal population. There was a decrease in QOL in the physical domains and an increase in vitality with age. PPS decreases health-related QOL in both sexes, more in female patients. QOL for physical domains decreases whereas vitality increases with age in both sexes.
