title: Contribution of weather to the seasonality of distal forearm fractures: a population-based study in Rochester, Minnesota.
abstract: Distal forearm fractures due to falls were more frequent in the winter (p < 0.0001) among Rochester men and women 35 years of age or older in 1952-89. The winter excess was partially explained by a greater relative risk of distal forearm fractures on days with freezing rain (1.65; 95% CI 1.28-2.13) or snow (1.42; 95% CI 1.17-1.74) among women under 65 years of age and on days with freezing rain (1.63; 95% CI 1.23-2.17) among older women. The greater seasonality of forearm compared with hip fractures is explained by the fact that more of them occur out-of-doors. However, residual effects of season after adjusting for daily weather conditions suggest that other factors may play a role.
