Prevalence of osteoporosis in otherwise healthy Indian males aged 50 years and above

Bone mineral density was studied in 200 healthy Indian men above 50 years age, without fractures or osteoporosis. Mean vitamin D was 18.96 ng/ml; other biochemical evaluations were normal. Bone density (femur neck) decreased with age; there was osteoporosis in 8.5 %, osteopenia in 42 %, while 49.5 % were normal. Vitamin D deficiency may have caused osteoporosis.
Osteoporosis is recognized as the disease of females; however, males are also affected and have serious consequences thereof. The present study aimed at studying the prevalence of osteoporosis in otherwise healthy Indian males aged 50 years or more and studying the factors affecting bone mineral density (BMD).
With informed consent, 200 healthy males aged 50 years or more without the history of fractures or diseases affecting the BMD were evaluated clinically (including anthropometry) and biochemically (serum calcium, phosphate, alkaline phosphatase, creatinine, albumin, 25-OH Vitamin D, intact parathyroid hormone (iPTH), and testosterone). The BMD was measured by single observer on Lunar DPX-NT at right proximal femur for least effects of artifacts. Calculation of T score and categorization as osteoporosis, osteopenia, and normal BMD was done as per WHO classification.
The mean age was 62.61 ± 7.64 years, and BMI was 23.90 ± 3.73 kg/m2. The testosterone levels were normal in 84 % subjects. The mean 25-OH vitamin D level was 18.96 ± 10.23 ng/ml; only 13.5 % subjects had normal levels. The mean iPTH level was 72.60 ± 43.77 pg/ml; 57 % subjects had normal iPTH (12–72 pg/ml). The other parameters studied were normal. The osteoporosis and osteopenia were more prevalent when BMD was evaluated at neck of femur (osteoporosis 8.5 vs 8 % at trochanter and 7.5 % at total right hip; osteopenia 42 vs 37 % at trochanter and 41 % at total right hip). The BMD deteriorated with age.
The osteoporosis affects 8.5 % of otherwise healthy males aged 50 years and above. Vitamin D deficiency is common in such group and maybe responsible for osteoporosis.
