| خلاصه مقاله | Background: Globally, approximately 30% of women over the age of 50 suffer from osteoporosis, a condition that significantly contributes to disability and mortality rates among the elderly. The objective of this research was to assess the prevalence of primary osteoporosis and low bone density, as measured by bone mineral density (BMD), in postmenopausal women, and to explore the associated sociodemographic, obstetric, and lifestyle risk factors.
Methods: The study, conducted in Tabriz, Iran, from August 2018 to April 2019, aimed to assess the prevalence of osteoporosis and low bone mass among postmenopausal women. A total of 850 women aged 50 to 65 years were randomly selected from health centers across the region. Out of these, 445 women underwent bone density measurement using DXA to evaluate their lumbar spine and femoral neck BMD.
The study collected comprehensive data on socio-demographic, obstetric, medical, physical activity levels, and anthropometric measurements through standardized questionnaires. The data were analyzed using descriptive and analytical statistics, including multivariate logistic regression, to identify risk factors associated with osteoporosis and low bone mass. The analysis was performed using SPSS version 21 software.
Results: The prevalence of primary osteoporosis based on lumbar vertebra T-score, femoral neck T-score, and total was 23.4%, 3.4%, and 24.5%, respectively, and the prevalence of primary osteopenia based on lumbar vertebra T-score, femur neck T-score, and total was 42%, 35.5%, and 43.6%, respectively. The present study showed that the odds of osteoporosis increased by increment of age (odds ratio [OR]: 1.18; 95% confidence interval [CI]: 1.07–1.30), but it decreased by increasing menopausal age (OR: 0.92; 95% CI: 0.85–1.01), body mass index (OR: 0.87; 95% CI: 0.78–0.97), arm circumference (OR: 0.84; 95% CI: 0.74–0.95), and education level (P = 0.028). It was higher in unmarried women (OR: 2.65; 95% CI: 0.99–7.08) and those with nonpersonal housing (OR: 4.02; 95% CI: 1.24–13.07).
Conclusion: Given the high prevalence of primary osteoporosis and low bone mass among postmenopausal women, there is a pressing need for health education to address modifiable risk factors and mitigate the complications associated with this disease. |
