Bone mineral density and pandemic.

The COVID-19 pandemic has significantly impacted physical health, including bone mineral density (BMD). This review aims to explore the effects of various pandemic-related factors such as reduced physical activity, stress, depression, dietary changes, and SARS-CoV-2 infection on BMD. Methods involved analyzing studies that investigate the impact of these factors on bone health, including observational studies, systematic reviews, and meta-analyses. Results show that decreased physical activity, depression, and changes in diet lead to a reduction in BMD, particularly in the lumbar spine and femoral neck. SARS-CoV-2 infection and the use of corticosteroids are also associated with an increased risk of osteoporosis. Additionally, cytokine storms induced by the virus further exacerbate bone resorption. The review also highlights the complex interaction between obesity, sedentary behavior, and BMD, which may contribute to either increased BMD in certain areas or lead to a higher risk of fractures. The study suggests that the pandemic may have long-term effects on bone health, emphasizing the need for preventive strategies, including promoting physical activity, managing stress, and cautious use of medications like corticosteroids. Further research is needed to understand the long-term consequences and to develop therapeutic interventions aimed at mitigating the adverse skeletal effects of COVID-19 and its treatments. Understanding the lasting impact on bone health requires a comprehensive approach considering the multifactorial aspects of the pandemic's effect on human physiology.
