Lower incidence of hip fractures among elderly Ethiopian immigrants to Israel: first assessment from the Israel National Trauma Registry (INTR) 2011-2020.

Abstract

The incidence of osteoporotic fractures in the aging Ethiopian population that immigrated to Western countries has not been reported. This study sought to provide a first assessment of the incidence of hip fractures in Ethiopian immigrants in Israel, as a proxy for osteoporosis in this population. This is an epidemiologic study of the incidence of hip fractures (HF) in people aged ≥ 50years in Israel, between 2011 and 2020. Data were extracted from the Israel National Trauma Registry (INTR). Annual age-adjusted HF incidence rates (IR), and standardized incidence ratios (SIR) among Ethiopian-born (EB) relative to non-EB subjects (others) were computed. During the study period, among subjects age ≥ 50 in the INTR, only 20.1% of the EB suffered a HF, in contrast to 32.3% of subjects from other origins (P < 0.0001). Although EB subjects were generally younger than their non-EB counterparts, the age at which they sustained a HF was similar: 80.45 ± 11.7years for EB vs. 79.44 ± 10.32years, P = 0.19. EB men were more likely to sustain a HF, as they represented 41.8% of all HF in their respective group, in comparison with 33.6% for others (P = 0.02). Annual IR of HF were lower for EB subjects throughout the study. Despite an initial rise in the SIR, these were also lower for most of the period. In Israel, EB subjects ≥ 50years still enjoy protection from HF. Our data require confirmation from other Western countries where the Ethiopian diaspora is aging. If a secular upward trend is observed, contributing risk factors should be identified to enable preventative measures.
