目的观察绝经期妇女蛋白摄入、体重减轻和骨矿物质密度的关系。方法 30例女性,每天摄取3139.5 J(1 cal=4.186 J),分为正常蛋白质摄取(A组:n=15)和高蛋白摄取(B组:n=15),共12周。观察体重和骨质矿物质密度变化。结果 A组体重减轻11.2%,B组体重减轻10.1%,A组骨质矿物质密度无显著变化[(-0.003±0.003)g/cm2,-0.3%],B组显著降低[(-0.0167±0.004)g/cm2,-1.4%,P<0.05]。结论较高的蛋白质摄取促进绝经期后妇女体重减轻和骨矿物质密度减低。
Objective To investigate the relationship between protein intake, weight loss and bone mineral density in postmenopausal women. Methods Thirty women with a daily intake of 3139.5 J (1 cal = 4.186 J) were divided into normal protein intake (group A: n = 15) and high protein intake (group B: n = 15) for 12 weeks. Body weight and bone mineral density were observed. Results The body weight loss in group A was 11.2% and that in group B was 10.1%. There was no significant change in group A ([-0.003 ± 0.003] g / cm 2 vs -0.3%], and in group B (-0.0167 ± 0.004) g / cm2, -1.4%, P <0.05]. Conclusion Higher protein intake promotes weight loss and decreased bone mineral density in postmenopausal women.
