Prevalence of osteoporosis, osteopenia and their related factors in post-menopausal women referring to Kurdistan densitometry center

ABSTRACT

Osteoporosis is the most common metabolic bone disease. This study deals with prevalence of osteoporosis, osteopenia and their related factors in post-menopausal women who had referred to Kurdistan densitometry center in Sanandaj. This descriptive-analytic study included 305 post-menopausal women without previous history of osteoporosis who had referred for densitometry to Kurdistan densitometry center from 1382 to 1383. Sampling method was census. Patients with secondary osteoporosis were excluded. Data were extracted from a questionnaires filled out by the subjects. Bone mineral densities of femoral neck and second to fourth lumbar vertebrae were measured by DXA method. The results were expressed on the basis of T-score. Osteoporosis and osteopenia were defined as T<-2.5 and -2.5 who criteria. Data were introduced into SPSS software and analyzed by descriptive and analytic methods. The mean values for age, weight and menopausal time period in the post-menopausal women were 57.7 +/- 7.6 years, 65.4 +/- 10.4 Kg and 10 +/- 8.3 years, respectively. The mean values for T-scores in the femoral neck and lumber spine were -1.83 +/- 1.18 and -1.57 +/- 1.01 and the global prevalence of osteoporosis and osteopenia were 34.4% and 69.8%, accordingly. Only 14.8% of the post-menopausal women had normal bone mineral density. Osteoporosis had statistically significant relationship with age, menopausal time period, weight and exercise [p<0.001]. History of previous fracture had an important relationship with osteoporosis of the neck of femur [P<0.001]. This study revealed that osteoporosis and osteopenia were common among the post-menopausal women and prevalence of osteoporosis was almost similar to the profiles of other developing countries, was higher than those of developed countries
