Abstract

Summary

The population of Oslo has the highest incidence of hip fracture reported. The present study shows that the overall incidence of distal forearm fractures in Oslo is higher than in other countries and has not changed significantly when comparing the incidence of 1998/99 with 1979.

Introduction

The population of Oslo has the highest incidence of hip fracture reported. The present study reports the incidence of distal forearm fracture in Oslo and the fracture rates of immigrants.

Methods

Patients aged ≥20 years resident in Oslo sustaining a distal forearm fracture in a one-year period in 1998/99 were identified using electronic diagnosis registers, patient protocols, and/or X-ray registers of the clinics in Oslo. Medical records were obtained and the diagnosis verified. The age- and sex-specific incidence rates were calculated and compared with those for 1979. Data on immigrant category and country of origin of the patients were obtained.

Results

The age-adjusted fracture rates per 10,000 for the age group ≥50 years were 109.8 and 25.4 in 1998/99 compared with 108.3 and 23.5 in 1979 for women and men, respectively (n.s.). The relative risk of fracture in Asians was 0.72 (95% CI 0.53–1.00) compared with ethnic Norwegians.

Conclusions

The overall incidence of distal forearm fractures in Oslo is higher than in other countries and has not changed significantly when comparing the incidence of 1998/99 with 1979. Furthermore, the present data suggest that Asian immigrants in Oslo have a slightly lower fracture risk than ethnic Norwegians.
