Cognitive function was assessed using the Digit Symbol Substitution, Delayed Recall, Intrusion Word Count, and Animal Fluency tests.

Compared to participants with osteoporosis alone, those with coexisting osteoporosis and low HGS performed significantly worse on the Digit Symbol Test (\u03b2 = \u22129.6; 95% CI, \u221216.7 to \u22122.5; p\u2009=\u2009.01) and had similar Delayed Recall scores (\u03b2 = \u22120.6; 95% CI, \u22121.3 to 0.1; p\u2009=\u2009.10). In participants with osteopenia and low HGS, a significant association was observed only for the Digit Symbol Test (\u03b2 = \u22128.1; 95% CI, \u221213.4 to \u22122.7; p\u2009&amp;lt;\u2009.01).
