目的 对比观察分期补钙和全程补钙预防骨质梳松的疗效。方法 使用钙尔奇D对B组实施全程补钙 ,对C组实施分期补钙 ,未实施补钙的A组作为对照。结果 B组和C组补钙治疗后孕妇缺钙症状发生率和妊娠合并症发生率明显低于A组 (P <0 .0 5) ,产后骨密度也高于A组 (P <0 .0 5) ,而B组与C组相比无明显差异 (P >0 .0 5)。结论 采取分期补钙预防孕妇骨质梳松 ,疗效可靠
Objective To compare the effects of staged calcium supplementation and full calcium supplementation in prevention of bone combing. Methods Calcium chloride D was used to perform whole-dose calcium supplementation in group B, and group A was administered calcium supplementation in group C and control group A without calcium supplementation. Results The incidence of calcium deficiency and pregnancy complications in B group and C group were significantly lower than those in A group (P <0.05), and the postpartum bone mineral density was also higher than that in A group (P <0. 0 5), while there was no significant difference between group B and group C (P> 0.05). Conclusions Adopting staged calcium supplement to prevent bone loss in pregnant women is reliable
