biologic sex contribute greatly to the decline in bone mineral density (BMD), other influences such as nutrition and physical activity serve as modifiable risk factors in the prevention and progression of the disease. The burden of osteoporosis necessitates improved understanding of the complexities of the disease process

statistically significant differences” not explained by the defects of selection bias that are found in empirical research when comparing socially distinct vulnerable and less vulnerable populations, specifically for the following variables: the quality of health care; healthcare use patterns; and health outcomes, including health status across

biological effects in the regulation of bone homeostasis,3 few studies have investigated the association of thyroid function and OA. Research has shown that D2 is upregulated in the cartilage of joints affected with OA compared with healthy joints.4,5 These findings suggest that local T3 availability
