摘要: Background: The role of dietary protein in bone metabolism is controversial. Objective: We investigated the associations intake with baseline mineral density (BMD) and rate loss over 3 y postmenopausal elderly women. Design: Women aged 65‐77 (n = 489) were enrolled an osteoporosis intervention trial. studied as a percentage energy BMD 96 women placebo group 96). also examined effect interaction calcium on BMD. Results: In cross-sectional study, higher was associated significantly (P 408 mg/d. There no significant hip longitudinal study group, there association between loss. Conclusions: highest quartile (x : 72 g/d) at only when exceeded seen loss, perhaps because sample size too small or follow-up period not long enough to detect changes.
