ASSESSMENT OF RISK FACTORS FREQUENCY AND THEIR IMPACT ON THE RELATIVE DEVELOPMENT RISK FOR OSTEOPOROTIC CERVICAL HIP FRACTURES

Abstract

Objective: to define significant risk factors for the development of low-traumatic cervical hip fractures and to calculate relative risks for the development of the given complication in patients with osteoporosis. Material and methods. The database of the consulting room for metabolic disorders containing records about clinical epidemiological examinations of 1760 patients older 50 has been used for the analysis. The methods of parametrical and nonparametric statistics were used for the mathematical analysis. The data were presented in Ме format (Q25 %; Q75 %). Manna-Whitney criterion was used to define the statistical importance. The frequency of the complications was analyzed on χ². The relative risk and confidential interval were calculated by means of SPSS 13.0. Result. It was established, that 1617 patients (91,9 % according to the appealability) detected osteoporosis and 109 (6,2 %) patients - osteopenic syndrome. The latent period for low-traumatic cervical hip fractures and development of osteoporosis made about 10 years. The relative risk of cervical hip fractures was statistically higher in women over 70 and made 2,25 (2,11¸4,42) in relation to the group of women aged from 50 to 70. The relative risk of hip fractures in the group of male smokers made up 1,24 (1,10¸3,11) and was statistically significant. As for women, the significant relative risk for the development of osteoporosis was established in the onset of menopause before 45 and made 2,76 (1,03¸7,80) or dysmenorrhea in the anamnesis 2,65 (1,75¸5,99).
