Abstract
Introduction. This study evaluated the correlation between selected socioeconomic and lifestyle characteristics and 10-year risk of fracture in persons aged 65+, living in small towns in the north-east of Poland.
Material and methods. 267 individuals (76 males and 191 females) aged 76.9 ±2.5 years, living in small towns in the north-east of Poland in independent households, took part in the study. The basic information on the socioeconomic situation and lifestyle of the subjects was gathered during a face-to-face interview. Dual energy X-ray absorptiometry (DXA) was used to determine bone mineral density (BMD) in the distal part of the forearm. The absolute 10-year risk of bone fracture was calculated in accordance with the algorithm developed by WHO and IOF.
Results. The average value of 10-year fracture risk was significantlyhigher in females than in males (31.4% vs. 14.5%, respectively), as was the probability of fracturing a thigh bone (13.7% vs. 6.1%, respectively), as was the probability of any fracture (23.9% vs. 10.1%, respectively), but BMD was lower (290.6 mg/cm2 vs. 405.2 mg/cm2, respectively). A higher 10-year risk of fracture was observed in people who used dietary supplements (T3 RB-10: OR = 3.23; 95% CI: 1.61-6.47) and a lower risk was observed in people who had a spouse/partner (T3 RB-10: OR = 0.14; 95% CI: 0.07-0.28), lived with someone (T3 RB-10: OR = 0.20; 95% CI: 0.08-0.48) and with a high physical activity (T2 RB-10: OR = 0.68; 95% CI: 0.47-0.99).
Conclusions. The 10-year risk of fracture was significantly gender-related. Lower bone mineral density and more than twice higher 10-year fracture risk, probability of fracturing a thigh bone and any fracture was observed in women than in men. The 10-year risk of fracture was higher in single persons, living alone, with a low physical activity and using dietary supplements.
