Purpose: The purpose of this study was to investigate bone mineral density(BMD) and fear of falling and falls efficacy in the middle and old aged women over 50 years.
Methods: The subjects consisted of 409 women. One-way ANOVA, Pearson’s correlations and multiple regression were used to test the BMD, fear of falling and falls efficacy scale by using SPSSWIN 12.0. The BMD of the calcaneus were measured with peripheral dual energy x-ray absorptiometry(DEXA).
Results: The average age was 63 years old and the average T-score was -3.21 in patient with osteoporosis, -1.72 with osteopenia, and .13 with normal. There were significant differences in the status of the BMD according to age(p=.000), height(p=.000), weight(p=.000), married status(p=.000), age of menarche(p=.002), and menopause(p=.002). The fear of falling was related with falls efficacy (r=-.247, p=.01), BMD(r=-.337, p=.01). Falls efficacy(β=-.21, p=.000)and BMD(β=-.26, p=.000) were predicting variables of fear of falling. The model explained 13% of the variance in fear of falling(F=27.38, p=.000).
Conclusion: Fear of falling and falls efficacy were related with the bone mineral density. Falls efficacy and BMD may be useful for the predicting fear of falling for women in middle and old age. Further studies with assessment of fall-related risk-factors and a longitudinal study are necessary to assess with falls efficacy, and BMD with age.
