Both up- and downregulated miRNAs correlated positively with BMI, WHtR, muscle function, malnutrition, PA score, vitamin D status, and TNF-α, IL-6, and CRP levels, whereas they correlated negatively with the intensity of pain, LBP score (OSW scores), and markers of bone metabolism (s-Ca, s-BAP, s-OC, and s-NTX). The gene discussed is BGLAP; the disease is nutritional deficiency disease.
