Factors associated with osteoporosis in older adult women treated at a referral center

Abstract

Objective: To analyze factors associated with osteoporosis in older adult women treated at a health care center for the older adult in northern Minas Gerais. Method: This is a cross-sectional and analytical study involving 647 women aged 60 years or older who underwent bone densitometry between 2015 and 2024. Data were collected from medical records, including sociodemographic, clinical, and lifestyle information. Osteoporosis was diagnosed using a T-score ≤ −2.5. Bivariate analyses and binary logistic regression were performed. Results: The results indicated a prevalence of osteoporosis of 46.4% among the participants. Multivariate analysis revealed that age equal to or greater than 80 years (OR = 1.60; 95% CI: 1.14–2.24) and body mass index (BMI) less than 27 kg/m2 (OR = 1.97; 95% CI: 1.42–2.74) are factors associated with osteoporosis. Conclusion: These findings demonstrate the high prevalence of osteoporosis in the study population, as well as the need to implement preventive strategies and interventions, especially in older adult women with low body weight.
