Stepwise regression analysis revealed that miRNAs (miR-146a, miR-558, miR-155, and miR-124a), adiposity markers, SGA, MAC, MAMC, TSF, SGA, TNF-α, IL-6, CRP, s-Ca, s-BAP, s-OC, and s-NTX levels, diet scores, and vitamin D deficiency were significantly associated with an incidence of LBP between 63.9% and 86.4% in older adults (Table 3). This evidence concerns the gene TNF and vitamin D deficiency.
