OBJECTIVE: This study was performed to assess the effects of vitamin D deficiency/insufficiency combined with a high body mass index (BMI) on paraspinal muscle (PSM) atrophy and pain intensity in postmenopausal women with lower back pain (LBP).
METHODS: In total, 365 postmenopausal women were analyzed in the study. We divided the women into four groups according to BMI and vitamin D status. Outcome measurements included PSM atrophy, fatty infiltration (FI) and severity of LBP. Binary logistic regression was used to analyze the odds ratio (OR), and the interaction between the BMI and vitamin D status was tested.
RESULTS: Compared with the control group, the high BMI with vitamin D deficiency/insufficiency group had a significantly increased risk of FI > grade 2 (OR = 10.69, p < 0.001), hand grip strength of <16 kg (OR = 8.96, p < 0.001), Short Physical Performance Battery score of ≤8 (OR = 3.69, p < 0.001) and visual analog scale (VAS) score of >3 (OR = 4.76, p < 0.001). A significant positive additive interaction was found between the BMI and vitamin D status on PSM atrophy.
CONCLUSION: Vitamin D deficiency/insufficiency combined with a high BMI was associated with PSM atrophy and LBP intensity in postmenopausal women. The interaction analysis showed a positive additive interaction between BMI and vitamin D status.
