Risk factors of osteoporosis in soldiers of the Armed Forces: A cross-sectional study from Western India.

ABSTRACT

Background: Osteoporosis may result from risk factors such as smoking, alcohol, low body mass index, less physical exercise, and dietary calcium deficiency. The risk of osteoporosis fractures can be reduced with lifestyle changes, which include diet, exercise, and preventing falls. The present study is an effort to measure the burden of risk factors of osteoporosis in adult male soldiers in the Armed Forces. Methods: The present study was a cross-sectional study among serving soldiers in South-Western part of India, and 400 participants consented to be included in the study. After obtaining informed consent, the questionnaire was distributed. Venous blood samples were collected to measure serum calcium, phosphorus, vitamin D, and parathyroid hormone (PTH). Results: The prevalence of vitamin D3 severe deficiency (<10 ng/mL) was 38.5%, and the prevalence of vitamin D3 deficiency (10-19 ng/mL) was 33%. Low serum calcium (<8.4 mg/dL) and serum phosphorus (<2.5 mg/dL) were found among 19.5% and 11.5%, respectively, whereas a raised serum PTH level (>66.5 pg/mL) was seen in 5.5% of the participants. A statistically significant association was found between consumption of milk and milk products and levels of calcium. With a cutoff value of 20 ng/mL for vitamin D3 deficiency, a statistically significant association was found for consumption of fish, physical activity, and sun exposure. Conclusion: A remarkably large percentage of otherwise normal healthy soldiers have deficiency or insufficiency of vitamin D and might be prone to osteoporosis. Despite significant advances in our understanding and management options for male osteoporosis, there still remain important gaps in knowledge which needs to be looked into.
