However, the impact of these diets on bone health is still under debate. Objective This systematic review and meta-analysis sought to study the impact of vegetarian and vegan diets on bone mineral density (BMD) and fracture risk. Data Sources A systematic search was conducted of PubMed, Scopus, and Science Direct, covering the period from the respective start date of each database to November 2017. Data Extraction Two investigators evaluated 275 studies against the inclusion criteria (original studies in humans, written in English or Spanish and including vegetarian or vegan diets and omnivorous diets as factors with BMD values for the whole body, lumbar spine, or femoral neck and/or the number of fractures as the outcome) and exclusion criteria (articles that did not include imaging or studies that included participants who had suffered a fracture before starting the vegetarian or vegan diet). The quality assessment tool for observational cohort and cross-sectional studies was used to assess the quality of the studies. Results Twenty studies including 37 134 participants met the inclusion criteria. Compared with omnivores, vegetarians and vegans had lower BMD at the femoral neck and lumbar spine and vegans also had higher fracture rates. Conclusions Vegetarian and vegan diets should be planned to avoid negative consequences on bone health. info:eu-repo/grantAgreement/ES/MEC/FPU014-00922 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 5.779 2018 NUTRITION & DIETETICS 8 / 86 = 0.093 2018 Q1 T1 2.319 2018 Nutrition and Dietetics 2018 Q1 Medicine (miscellaneous) 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-2411-9538 Miguel-Berges, Maria Luisa Universidad de Zaragoza (orcid)0000-0002-0520-1640 Gómez-Bruton, Alejandro Universidad de Zaragoza (orcid)0000-0003-0454-653X Moreno, Luis Alberto Universidad de Zaragoza (orcid)0000-0002-8374-3410 Julian, Cristina 1006 255 Universidad de Zaragoza Dpto.
