Objectives: The aim of this meta-analysis was to investigate the relationship between prevalence and risks of osteoporosis or osteoporotic fracture and non-alcoholic fatty liver disease (NAFLD).
Methods: Five databases, including PubMed, Web of Science, Embase, Scopus and Cochrane Library, were searched since the conception of these databases until December 2021. The cohort studies, cross-sectional analyses or case-control studies evaluating the relationship between osteoporosis or osteoporotic fracture and NAFLD were retrieved from these databases. Relevant data were extracted from the included studies, and a meta-analysis was performed.
Results: A total of seven studies were included. The prevalence of osteoporosis or osteoporotic fractures was higher in the NAFLD group than in the non-NAFLD group [OR = 1.17, 95%CI(1.04,1.31)], while the prevalence of osteoporosis was higher in the NAFLD group than in the non-NAFLD group [OR = 1.46, 95%CI (1.21,1.77) and OR = 1.48, 95%CI (1.31,1.68), respectively] in men and women. The risk of osteoporosis or osteoporotic fractures was higher in the NAFLD group than in the non-NAFLD group [OR = 1.33,95%CI (1.24,1.44) and OR = 1.57,95%CI (1.08,2.29), respectively]. The risk of osteoporosis or osteoporotic fractures was higher in male and female NAFLD groups than that in the non-NAFLD group [OR = 1.29, 95%CI(1.14,1.47) and OR = 1.36, 95%CI (1.25,1.48), respectively]. After parameter adjustment, the risk of osteoporosis or osteoporotic fracture was higher in the male NAFLD group than in the non-NAFLD group [OR = 2.10, 95%CI(1.36,3.25)], while no significant difference was found among women [OR = 1.13, 95%CI (0.86,1.48)].
Conclusions: The prevalence and risk of osteoporosis or osteoporotic fractures were significantly associated with NAFLD in men and women.
