Study Overview
A 2026 study published in the Archives of Osteoporosis examined the relationship between osteoporosis prevalence and fragility fracture burden in older Taiwanese men and women. The research, led by Lee YY and colleagues, analyzed data from 2,093 men who underwent clinical dual-energy X-ray absorptiometry (DXA) between 2021 and 2023. Of these, 2,031 men met eligibility criteria and were matched 1:1 with 2,031 age-matched women based on demographic factors. Osteoporosis was defined as a T-score ≤−2.5 at the lumbar spine, femoral neck, or total hip. Fracture prevalence was determined through radiographs and electronic medical records. The study aimed to clarify whether lower osteoporosis rates in men correspond to reduced fracture risk, given that men experience higher post-fracture mortality and disability compared to women.
Key Findings
The study found that osteoporosis prevalence was significantly lower in men (32.4%) compared to women (51.4%; P < 0.001). However, vertebral fracture prevalence was nearly identical between the sexes (22.7% in men vs. 22.8% in women; P = 0.940), and hip fracture rates did not differ significantly (6.1% vs. 5.0%; P = 0.150). Sensitivity analyses revealed that men had a higher prevalence of moderate-to-severe vertebral fractures (Genant grade ≥2: 16.9% vs. 12.3%; P < 0.001). After adjusting for age, body mass index, and osteoporosis, male sex remained independently associated with both vertebral and hip fractures. These results highlight a dissociation between osteoporosis prevalence and fracture burden in older men, suggesting that traditional bone density metrics may not fully capture fracture risk in this population.
Discussion of Clinical Implications
The study underscores the limitations of relying solely on bone mineral density (BMD) to assess fracture risk, particularly in men. While osteoporosis is less common in men, their fracture burden remains substantial, with vertebral and hip fractures occurring at rates comparable to women. The authors note that men face higher post-fracture mortality and poorer functional outcomes, emphasizing the need for more comprehensive risk assessment strategies. These findings align with broader evidence that male osteoporosis is an underrecognized public health issue, with men accounting for 25–40% of all fragility fractures despite lower osteoporosis prevalence. The study’s use of identical DXA protocols within the same healthcare system strengthens its validity, though the authors acknowledge the need for further research to explore underlying mechanisms and risk factors specific to men.
Implications for Spine Health and Chiropractic Care
The study’s focus on vertebral fractures highlights the importance of spinal health in aging populations. Vertebral fractures, often asymptomatic, can lead to chronic pain, reduced mobility, and decreased quality of life. Chiropractic care may play a role in managing spinal health by addressing biomechanical factors and supporting musculoskeletal resilience. However, the study’s findings suggest that traditional BMD measurements alone may not adequately identify men at risk for fractures, necessitating integrated approaches that include clinical risk factors. Chiropractors may benefit from incorporating broader fracture risk assessments into patient evaluations, particularly for older male patients, to proactively address spinal health and prevent complications from undetected fractures.
Limitations and Future Research
The authors did not explicitly outline limitations in the provided text, but the study’s retrospective design and reliance on existing medical records may introduce potential biases. Additionally, the sample was restricted to individuals undergoing DXA, which could limit generalizability to broader populations. While the study compared age-matched men and women within the same healthcare system, it did not explore factors such as lifestyle, hormonal status, or genetic predispositions that might influence fracture risk. Further research is needed to validate these findings in diverse populations and to investigate the biological and clinical factors driving the observed dissociation between osteoporosis prevalence and fracture burden in men.
