Recent hip fracture trends in Sweden and Denmark with age-period-cohort effects.

ABSTRACT: This study used nationwide hip fracture data from Denmark and Sweden during 1987-2010 to examine effects of (birth) cohort and period. We found that time trends, cohort, and period effects were different in the two countries. Results also indicated that hip fracture rates may increase in the not so far future.

Introduction

The reasons for the downturn in hip fracture rates remain largely unclear but circumstances earlier in life seem important.

Methods

We ascertained hip fractures in the populations ≥50 years in Denmark and Sweden in national discharge registers. Country- and sex-specific age-period-cohort (APC) effects during 1987-2010 were evaluated by log-likelihood estimates in Poisson regression models presented as incidence rate ratios (IRR).
