#妇幼卫士讲甲状腺与优生优育[超话]# 啥时候开始生孩子？#让她健康##微博健康公开课#
❝
为应对人口老龄化，三孩政策应运而生。国家提倡适龄婚育，优生优育，一对夫妻可以生育三个子女。
生不生？生几个？啥时候生？最晚啥时候生？这些都是问题。
❞
众所周知，女性怀孕率随年龄增长而下降。作为不孕症的独立危险因素，慎重考虑开始备孕时间对于女性来说显得尤其重要。
为了生育理想数量孩子的家庭，应该从什么时候开始备孕？
一项有意思的研究为我们提供了这样的参考。
为了≥90%的机会实现一个、两个或三个孩子的家庭，如果接受试管婴儿助孕，夫妻应该分别在女性伴侣≤35、≤31和≤28岁时开始尝试怀孕。如果不接受试管婴儿助孕，分别想要一个、两个或三个孩子的家庭，则应不迟于32、27和23岁时开始。
如果决定生育2个及以上的子女，最佳的生育间隔应该是多久呢？
世界卫生组织（World Health Organization，WHO）和美国国际开发署都建议，在一次正常生产后，生育间隔应大于2年、小于5年。生育间隔在此范围内，母婴健康受到损伤的概率最小。这一建议也与联合国儿童基金会所推荐的2年母乳喂养时间相呼应。
两次妊娠之间应有充足的间隔，一是产后母亲的身体需要一个恢复的过程，时间充分能帮助母亲恢复身体，补充孕期和哺乳期消耗的营养，也给母乳喂养留出足够的时间。二是将来家里的两个孩子在年龄上有一定差距，但差距又不会太大，对孩子的共同成长也是有好处的。
在此也强调一下，如果间隔没到两年就怀孕了，在医生的评估下没有太大问题，那就可以继续妊娠，没有必要刻意为了达到两年而做一些不必要的干预。
希望大家积极响应国家号召，生得顺心顺意！
