Insights
This study reveals that osteoporosis prevalence in Thai men increases with age, particularly at the femoral neck in urban populations. Findings provide crucial bone mineral density data for diagnosing osteoporosis in Thai men.
Area of Science:
- Bone health and osteoporosis research.
- Epidemiology of bone diseases in Asian populations.
Background:
- Osteoporosis affects both men and women, yet epidemiologic data for Thai men is limited.
- Understanding osteoporosis prevalence in Thai men is crucial for public health initiatives.
Purpose of the Study:
- To assess bone mineral density (BMD) in Thai men.
- To determine the prevalence of osteoporosis among Thai men.
Main Methods:
- Dual-energy X-ray absorptiometry (DXA) was used to measure BMD.
- 412 Thai men aged 51 ± 16 years were studied in Bangkok and Khon Kaen.
Main Results:
- Peak bone mineral density (BMD) was observed in men aged 20-29 years.
- Overall osteoporosis prevalence was 12.6% (femoral neck) and 4.6% (lumbar spine).
- Prevalence increased with age, higher in urban men at the femoral neck; age and lower weight correlated with lower BMD.
Conclusions:
- The study provides essential descriptive BMD data and reference values for diagnosing osteoporosis in Thai men.
- This research highlights the prevalence and risk factors of osteoporosis in this demographic.
Background:
Osteoporosis is a growing health problem not only in women but also in men. However, there is a scarcity of epidemiologic data to study osteoporosis in Thai men.
Objectives:
To examine the bone mineral density (BMD) and to determine the prevalence of osteoporosis in Thai men.
Material And Method:
A total of 412 men (159 from Bangkok and 253 from Khon Kaen, respectively) averaging 51 +/- 16 years of age, were measured for BMD at the femoral neck and lumbar spine by dual energy X-ray absorptiometry (LUNAR Corporation, WI, USA).
Results:
The peak BMD was observed in men 20-29 years of age at both the femoral neck (mean +/- SD, 1.10 +/- 0.15 g/cm2) and lumbar spine (mean +/- SD, 1.17 +/- 0.13 g/cm2). The prevalence of osteoporosis in the entire group of subjects was 12.6, 4.6 and 3.9 per cent at the femoral neck, lumbar spine and both sites, respectively. The prevalence of osteoporosis increased with advancing age and was significantly higher at the femoral neck in urban men than rural men (18.2 vs 9.2 per cent, p < 0.05) but comparable at the lumbar spine (5.0 vs 4.3 per cent, p = 0.81). The correlation between femoral neck and lumbar spine BMDs was 0.53 (p < 0.001). In univariate analysis, increased age, lower weight and lesser height were each associated with lower femoral neck BMD, whereas only lower weight and lesser height were associated with lower lumbar spine BMD. However, when the three factors were entered simultaneously, only increased age and lower weight were significantly associated with lower femoral neck BMD and only lower weight had a significant association with lower lumbar spine BMD.
Conclusion:
The present study demonstrated descriptive BMD data, normal BMD reference values for diagnosis and reported the prevalence of osteoporosis in Thai men.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
