长时间哺乳可能会导致女性骨密度下降

对维持体内钙稳定平衡,维生素D起着很重要的作用。一些假设认为女性在妊娠和泌乳期时,骨密度与维生素D情况密切相关。最新一项研究表明,女性泌乳期与骨密度相关,但与维生素D情况无关。

Petra Brembeck假设长期泌乳,维生素D进入乳汁内,会导致女性体内维生素D的减少;但是在研究中研究者们并没有发现产后1年女性体内维生素D的变化,泌乳期和维生素D的任何关系也没有发现。

阳光和维生素D的补充是仅存的与女性维生素D有关的因素。

同时研究者发现,当泌乳期≥4个月,在产后4个月女性骨密度下降约4%,尤其是腰椎、髋部和小腿。如果泌乳期≥9个月,一直到18个月时,骨密度仍低于基线水平。

该研究对95名女性在产后监测了18个月,研究结果表明,长时间的泌乳会导致女性骨密度的下降,摄入更多的钙或许可以对该风险起到保护作用。未来还需要更多的研究如骨密度什么时候恢复、会不会影响以后骨折风险等。
