Relationship between fracture risk and diet in postmenopausal women
In this study, a longitudinal study of 48,584 postmenopausal women (mean age 61.4 years) investigated the association between the incidence of osteoporotic fractures and dietary intake of calcium, magnesium, and soy isoflavones. Investigate. The association between dietary intake and fracture risk was evaluated using multivariate Cox regression. During a median follow-up of 10.1 years, 4.3% experienced an osteoporotic fracture.
Among women with a calcium/magnesium (Ca/Mg) ratio of 1:7 or less, osteoporotic fracture risk was reduced by approximately 40% to 50% at daily calcium intakes above 400 mg compared with 400 mg or below. Among women with a history of fractures, a higher intake of soy isoflavones was associated with a lower risk of osteoporotic fractures. No significant association was observed between magnesium intake and osteoporotic fracture risk.
