The aim of this observational study was to investigate whether dietary flavonoid intake was associated with bone mineral density (BMD) and bone resorption in a large group of peri-menopausal Scottish women.<\/p>\n<p>METHODS: Over 3000 women completed a food frequency questionnaire as part of an osteoporosis screening study. The diets were analysed for flavonoid intakes using a food composition database. BMD was measured at the femoral neck (FN) and lumbar spine (LS) by DXA. Free pyridinoline (PYD) and deoxypyridinoline (DPD) were measured by HPLC in second early morning fasted urine samples.<\/p>\n<p>RESULTS: The mean flavonoid intake of the diet was 307 &plusmn;199 mg\/d. The catechin family contributed the most to flavonoid intakes (55%), and the flavones the least (&lt;1%). Associations were found between energy adjusted total flavonoid intakes and BMD at the FN and LS (FN r=0.054. LS r=0.036, p= 0.05). Annual % change in BMD was associated with intakes of procyanidins and catechins (p=0.05), and flavanones were negatively associated with bone resorption markers (PYD r=-0.049. DPD r=-0.057, p=0.001). These associations were still seen after adjusting for confounders.<\/p>\n<p>CONCLUSION: Dietary flavonoid intakes are associated with BMD, supporting the evidence from animal and cellular studies.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-39945","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Bone and Musculoskeletal Research Programme, Health Sciences Building, University of Aberdeen, Foresterhill, Aberdeen.
