CONTEXT: Hip fractures are a major public health concern. Understanding their epidemiologic and biological links with diet and cardiovascular risk may have important implications for prevention. OBJECTIVE: To assess the dose-response association of Mediterranean diet (MD) adherence with the risk of hip fracture. DATA SOURCES: A systematic search was conducted in the PubMed, Scopus, and Web of Science databases for prospective studies. Search terms were "Mediterranean Diet" and "Fracture." DATA EXTRACTION: Data were extracted from 8 studies, encompassing 15 cohorts that included 503 174 individuals. Methodological quality was assessed using the Risk of Bias in Nonrandomized Studies of Interventions. DATA ANALYSIS: The "meta" and "dosresmeta" packages were used in R Studio Software. The results demonstrated that high and moderate MD adherence were associated with a reduced risk of hip fracture (relative risk [RR] = 0.71 [95% CI, 0.55-0.91]; and RR = 0.78[(95% CI, 0.65-0.93], respectively). The effect of the association was similar in men and women. The dose-response pattern of the association was linear: each point increase in MD adherence was associated with a 5.25% reduction in hip fracture risk. CONCLUSIONS: Adherence to MD is associated with a reduction in hip fracture risk, following a linear dose-response pattern. This supports the promotion of this dietary pattern for improving bone health. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42023402284.
