Using a simple preliminary screening tool to explore related factors of osteoporosis in the elderly of southern Taiwan.

ABSTRACT

ABSTRACT The aims of this study were to use a simple screening tool to explore related factors with osteoporosis in the elderly in the community of southern Taiwan.This was an observational cross-sectional study using Osteoporosis Self-Assessment Tool for Asia (OSTA), Osteoporosis Self-Assessment Tool for Taiwanese (OSTAi), and the basic demographic information to identify osteoporosis in the participants. This study collected data from 200 participants aged 65 and above and living in southern Taiwan.The prevalence of osteoporosis among elders in the community was 30.5% (OSTA) and 58.0% (OSTAi), respectively. The prevalence of osteoporosis determined by OSTA and OSTAi in female (33.1% and 63.1%, respectively.) was higher than in male (25.7% and 48.6%, respectively.). Risk factors such as gender, age, and body mass index (BMI) were significantly associated with osteoporosis (P < .001). Using OSTA and OSTAi to assess the risk for osteoporosis, for every 1 year of age increase, the odds ratio (OR) value of osteoporosis increased by 1.84 and 1.50 times, respectively (P < .001); for every 1 kg/m2 increase in BMI, the OR of osteoporosis decreases by 0.36 and 0.44 times, respectively. The results of this study can be used a simple tool of OSTA and OSTAi self-examination to screen potential high-risk groups for osteoporosis in the community.OSTA and OSTAi can screen for possible high-risk groups early and without invasive examinations and self-examination tools in a hospital. Low BMI poses higher risks of osteoporosis for the elderly, so increasing functional ability, improving muscle strength, maintaining exercise habits and keeping proper weight could prevent osteoporosis in the seniors.
