Background: It is estimated that over 200 million people worldwide have osteoporosis. The prevalence of osteoporosis is continuing to escalate with the increasingly aging population. The major complication of osteoporosis is an increase in fragility fractures leading to morbidity, mortality, and decreased quality of life. This investigation profiled the incidence and risk of osteoporosis in adult women from a rural setting using ultrasonic bone scanning technology.
Methods: Between 2001 and 2005, adult female subjects (n = 323) in the age range of 40-87 were drawn from an independent, community dwelling, convenience sample. Bone mineral density T-scores were evaluated using heel ultrasonometry. Demographic and risk factor data, Merck Osteoporosis Evaluation SCORE questionnaire data, and the Osteoporosis Risk Assessment questionnaire data were analyzed.
Results: Results of these scans indicate that 25% of the total population had a T-score ≤ −1.0, implying a 1.5-to 2.0-fold increase in risk ratio of hip or spinal fracture for each standard deviational decrease. Age at menopause and weight had a positive correlation with T-scores. While the overall scores on the Merck SCORE questionnaire were inversely correlated to T-scores, no significant correlation was found between the Osteoporosis Risk Assessment questionnaire and T-score data. Additionally, women who had taken estrogen had significantly higher T-scores (p = 0.038) than those who had not.
Conclusion: That approximately 25% of this sample has low bone mass or osteoporosis underscores the importance of early screening in order to develop preventative awareness and provide education on bone health management. This finding has particularly important ramifications, since the sample was rural women, who typically have limited access to diagnostic bone density procedures.
