Osteoporosis in men—East and West: Can the twain meet? A perspective from Asia

Osteoporosis in men remains a significantly underrecognized condition, with notable differences in bone mineral density (BMD) and fracture risk between Asian and Western populations. Despite 30% of hip fractures globally occurring in men, they are less likely to be diagnosed or treated for osteoporosis, especially in resource-limited settings. Given these disparities, a deeper understanding of osteoporosis epidemiology and treatment efficacy in men is essential, particularly in Asian populations.
This review synthesizes the latest evidence on the epidemiology, screening, and treatment of osteoporosis in men, with a focus on genetic, environmental, and epidemiological disparities between Eastern and Western populations. Additionally, the review examines existing controversies surrounding fracture risk screening in men and evaluates the efficacy and cost-effectiveness of pharmacological treatments such as bisphosphonates,
denosumab, and anabolic agents.
Asian men exhibit lower peak BMD compared to their Caucasian counterparts, leading to potential misdiagnoses when using Caucasian-based BMD reference ranges. Screening tools like the Fracture Risk Assessment Tool (FRAX)® show variability in performance across populations. Data on pharmacological treatment in men remain limited, although studies suggest comparable benefits to those observed in women. Larger studies,
particularly in male and Asian populations, are urgently needed to refine diagnostic and therapeutic guidelines.
Osteoporosis in men is underdiagnosed and undertreated globally, with pronounced disparities between populations. Current diagnostic tools and treatment protocols are not fully tailored to male and Asian populations.
There is an urgent need for longitudinal studies focusing on male-specific osteoporosis management to reduce fracture risk and improve outcomes.
