Abstract Title: 

Soy isoflavones prevent bone resorption and loss, a systematic review and meta-analysis of randomized controlled trials.


Osteoporosis is a common bone disease characterized by reduced bone mass resulting from continuous bone resorption.PubMed, Scopus, and Embase were searched to find published trials on the effect of soy isoflavones on bone mineral density (BMD) and bone turnover markers (bone-specific alkaline phosphatase, osteocalcin, osteoprotegerin, pyridinoline, deoxypyridinoline, C-telopeptide, and N-telopeptide). Random-effects inverse-variance model was used to calculate the pooled effects.A total of 5313 articles were found, screened, and assessed for eligibility, and finally 52 trials were included in the meta-analysis. Consumption of soy isoflavones caused significant improvement in BMD of lumbar spine (mean difference (MD) = 0.76%; 95% CI: 0.09, 1.42%; = 0.03), hip (MD = 0.22%; 95% CI: 0.02, 0.42%; = 0.04), and femoral neck (MD = 2.27%; 95% CI: 1.22, 3.31%;
