ABSTRACT
Quantitative ultrasound of bone is cheaper and easier than other bone mineral density measurement techniques. Because of that, it is useful for population screening. We determined calcaneous bone mineral density with a SAHARA clinical bone sonometer in 182 subjects [155 females (85.1%), 27 males (14.9%)] who had attended a community education program. Body fat percentage was evaluated by bio-electrical impedance analysis (OMRON BF 302) and dominant handgrip strength was measured with a JAMAR hand grip dynamometer. Body mass index, duration of menopause, family history of osteoporosis and/or spontaneous fracture, weekly consumpt ion of milk and milky products, duration of weekly exercise and drug history for calcium, steroids, and thyroxine were registered. Body fat percentage was 33.6 ± 7.3%, body fat weight was 23.7 ± 7.5 kg, handgrip strength was 29.5 ± 7.9 kg. Cheese consumption was <100 gr/week in 11.5%, between 100-150 gr/week in 69.8%, and >150 gr/week in 18.7%. The average t score was -0.95 [95% confidence interval (1.10; -0.79)] and z score was -0.60 [95% confidence interval (0.75; -0.44)]. Osteoporosis was detected in 5.4% (10/182) (t score <2.5) and osteopenia was seen in 50% (91/182) (-2.5 < score>0.005). We detected a negative correlation between t score and age (r=-0.28, p=0.005). There was no other correlation between t and z scores and body mass index, duration of menopause, family history of osteoporosis and/or spontaneous fracture, handgrip strength or weekly consumption of milk and milky products. When factors affecting calcaneous bone mineral density were researched, the age of subjects was found to have a negative effect on t score (t=-2.414, p=0.034), however, weekly consumption of cheese was found to have a positive effect on t score (t=4.299, p=0.001). There was no direct effect of body fat percentage and weight or handgrip strength on calcaneous bone mineral density. However, age and consumption of cheese were found to affe ct calcaneous bone mineral density.
