ABSTRACT

Objective To investigate the awareness of osteoporosis and its influential factors in middle-aged and older people. Methods By using self-designed questionnaire, 354 middle-aged and old people were investigated as to their awarness of osteoporosis in Chajiao street community in Guangzhou. Among them, 58 people were measured the bone density in the calcaneal bone by Ultrasound. Results The average score of the questionnaire was 9.46 ± 5.13, and the accuracy was 39.4%. In the diagnosis and treatment, the accuracy was just 17.8%. The diet (the accuracy in 54%) and sport (the accuracy in 50.3%) were good. The statistical analyses showed the linear relationship between the T value of bone density and the age (P = 0.021), between the T value and the score (P = 0.047). Wilcoxon rank sum test found that the T value between female and male was significantly different (Z = -3.749, P < 0.000). With multiple linear regression analysis, the T value had a linear correlation with the score (F = 4.224, P = 0.045) positively. Conclusions Currently, the awareness of osteoporosis in the middle-aged and old people was inadequate. To better prevent osteoporosis, the propogation of knowledge and guidance provided by clinicians in osteoporosis should be improved necessarily and emergently.
