Evaluation of postmenopausal osteoporosis according to age groups and body mass index categories

Objective: In clinical practice, it is recommended to create different groups when assessing the elderly population (≥65 years). However, differences in groups have not been sufficiently investigated in terms of osteoporosis. We aimed to evaluate age and BMI (kg/m2) groups in postmenopausal women for osteoporosis.Methods: Postmenopausal women were classified into pre-elderly (50-65 years) and elderly groups: young old and middle old. Additionally, they were categorized as normal weight, overweight, and obesity. These age groups and BMI categories were evaluated in terms of osteoporosis.Results: Pre-elderly group had significantly lower spine osteoporosis rates than young old and middle old groups (p0.05). Pre-elderly group had significantly lower hip osteoporosis rates than elderly groups (p=0.001), and the young old group had lower hip osteoporosis rates than middle old group (p=0.001). Normal weight group had higher spine osteoporosis rates than overweight group (p=0.005) and obesity group (p=0.001). Also, overweight group had significantly higher spine osteoporosis rates than obesity group (p=0.001). Normal weight group had higher hip osteoporosis rates than overweight group and obesity group (p=0.001). Also, overweight group had higher hip osteoporosis rates than obesity group (p=0.001). Age scores were correlated inversely with T-scores in the spine and hip (p=0.001). There were significant positive correlations between BMI and T-scores in the spine and hip (p=0.001).Conclusion: Elderly and thin women are more associated with osteoporosis than pre-elderly and obese women. As age increases and BMI decreases, osteoporosis rates increase.
