There are only minor changes in quality of life in patients with Scheuermann's disease.

INTRODUCTION

The impact of Scheuermannss disease (SD) on health-related quality of life (HRQoL) is unclear. The aim of this study was to study HRQoL based on The Medical Outcome Study Short Form-12 (SF-12) in adult life in a group of SD patients.

MATERIAL AND METHODS

A total of 46,418 twins were sent a questionnaire. 75.3% answered. Included in the questionnaire were questions from the SF-12. We compared SF-12 values in SD patients and control patients. We also identified 259 "non-concordant" twin pairs and compared SF-12 values from the SD twin with values from the healthy twin.

RESULTS

In all, 943 persons were identified to have SD, leaving 33,064 persons in the control group. SF-12 Physical Component Summary (PCS) (mean (standard deviation)) was found to be 50.50 (9.89) in SD and 53.21 (8.00) in controls (p < 0.001), and SF-12 Mental Component Summary (MCS) was found to be 51.52 (8.49) in SD and 51.81 (8.45) in controls (p = 0.71). In the non-concordant twin pairs, SF-12 PCS was found to be 50.74 (9.87) in SD and 52.74 (8.84) in controls (p < 0.001), and SF-12 MCS was found to be 53.91 (8.19) in SD and 53.72 (8.70) in controls (p = 0.64).

CONCLUSION

SF-12 PCS is moderately, though highly statistically significantly worse in SD patients than in controls in this big group of twins. We found no statistical difference in SF-12 MCS between the two groups. SD patients evaluate their physical health worse and their mental health like controls.
