In recent decades, the protective role of obesity in the development of osteoporosis is questioned. The aims of this study are the following: to evaluate the differences in bone turnover markers between postmenopausal women with and without obesity and to compare the risk of fracture at five years between these groups. Methods: An observational longitudinal prospective cohort study of postmenopausal women with obesity (O) (body mass index (BMI) &gt; 30 kg\/m2) and non-obesity (NoO) (BMI &lt; 30 kg\/m2) is designed. 250 postmenopausal women are included in the study (NoO: 124 (49.6%) and O: 126 (50.4%)). It measures epidemiological variables, dietary variables (calcium intake, vitamin D intake, smoking, alcohol consumption, and physical activity), biochemicals (\u03b2-crosslap, type I procollagen amino-terminal peptide (P1NP), 25OH-vitamin D, and parathyroid hormone (PTH)), anthropometric variables, and fracture data five years after the start of the study. The mean age is 56.17 (3.91) years. Women with obesity showed lower levels of vitamin D (O: 17.27 (7.85) ng\/mL, NoO: 24.51 (9.60) ng\/mL; p &lt; 0.01), and higher levels of PTH (O: 53.24 (38.44\u201365.96) pg\/mL, NoO: 35.24 (25.36\u201342.40) pg\/mL; p &lt; 0.01). Regarding the bone formation marker (P1NP), it was found to be high in women without obesity, O: 45.46 (34.39\u201355.16) ng\/mL, NoO: 56.74 (45.34\u201370.74) ng\/mL; p &lt; 0.01; the bone resorption marker (\u03b2-crosslap) was found to be high in women with obesity, being significant in those older than 59 years (O: 0.39 (0.14) ng\/mL, NoO 0.24 (0.09) ng\/mL; p &lt; 0.05). No differences are observed in the risk of fracture at 5 years based on BMI (OR = 0.90 (95%CI 0.30\u20132.72); p = 0.85). Conclusions: Postmenopausal women with obesity showed lower levels of bone formation markers; older women with obesity showed higher markers of bone resorption.<\/jats:p>","DOI":"10.3390\/nu14081617","type":"journal-article","created":{"date-parts":[[2022,4,13]],"date-time":"2022-04-13T23:07:16Z","timestamp":1649891236000},"page":"1617","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Influence of Obesity on Bone Turnover Markers and Fracture Risk in Postmenopausal Women"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3144-343X","authenticated-orcid":false,"given":"Juan J.","family":"L\u00f3pez-G\u00f3mez","sequence":"first","affiliation":[{"name":"Department of Endocrinology and Nutrici\u00f3n, Hospital Cl\u00ednico Universitario de Valladolid, 47003 Valladolid, Spain"},{"name":"Centro de Investigaci\u00f3n Endocrinolog\u00eda y Nutrici\u00f3n (IENVA), University of Valladolid, 47002 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1723-217X","authenticated-orcid":false,"given":"Jos\u00e9 L.","family":"P\u00e9rez-Castrill\u00f3n","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n Endocrinolog\u00eda y Nutrici\u00f3n (IENVA), University of Valladolid, 47002 Valladolid, Spain"},{"name":"Department of Internal Medicine, Hospital Universitario Rio Hortega, 47012 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabel","family":"Garc\u00eda de Santos","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Valladolid, 47002 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda","family":"P\u00e9rez-Alonso","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n Endocrinolog\u00eda y Nutrici\u00f3n (IENVA), University of Valladolid, 47002 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olatz","family":"Izaola-Jauregui","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Nutrici\u00f3n, Hospital Cl\u00ednico Universitario de Valladolid, 47003 Valladolid, Spain"},{"name":"Centro de Investigaci\u00f3n Endocrinolog\u00eda y Nutrici\u00f3n (IENVA), University of Valladolid, 47002 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Primo-Mart\u00edn","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Nutrici\u00f3n, Hospital Cl\u00ednico Universitario de Valladolid, 47003 Valladolid, Spain"},{"name":"Centro de Investigaci\u00f3n Endocrinolog\u00eda y Nutrici\u00f3n (IENVA), University of Valladolid, 47002 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1745-9315","authenticated-orcid":false,"given":"Daniel A.","family":"De Luis-Rom\u00e1n","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Nutrici\u00f3n, Hospital Cl\u00ednico Universitario de Valladolid, 47003 Valladolid, Spain"},{"name":"Centro de Investigaci\u00f3n Endocrinolog\u00eda y Nutrici\u00f3n (IENVA), University of Valladolid, 47002 Valladolid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"59","DOI":"10.1007\/s11657-011-0060-1","article-title":"Osteoporosis: Burden, health care provision and opportunities in the EU: A report prepared in collaboration with the International Osteoporosis Foundation (IOF) and the European Federation of Pharmaceutical Industry Associations (EFPIA)","volume":"6","author":"Kanis","year":"2011","journal-title":"Arch.
