推 forsakesheep: 你板人查文献说35岁以上才有差 就 https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2708196 In this cohort study of 148544 pregnancies, maternal mortality or severe morbidi ty risks were increased at short interpregnancy intervals among women 35 years o r older but not for women aged 20 to 34 years; in contrast, increased risks of a dverse fetal and infant outcomes and spontaneous preterm delivery were more pron ounced for women aged 20 to 34 years than for those 35 years and older. Modest i ncreases in risks of small-for-gestational-age birth and indicated preterm deliv ery at short intervals were not meaningfully different across maternal age group s. 这篇说对孕妇本身的风险来看，35岁以上的孕妇短间隔怀孕有明显风险，20到34岁看不出明 显风险 本质上是高龄产妇问题 但是对婴儿早产、体重不足、死胎的风险有提高 https://www.bmj.com/content/349/bmj.g4333 This study questions the causal effect of short interpregnancy intervals on adve rse birth outcomes and points to the possibility of unmeasured or inadequately s pecified maternal factors in previous studies. 这篇则说用三胎的孕妇的资料来看，对於婴儿的风险可能不适合用单纯用短间隔怀孕来认定 。 还要考虑孕妇本人的其他因素。 意思就是某些短期怀孕的孕妇可能会因为个人习惯或社经地位的问题导致胎儿出毛病。 我昨天半夜睡不着叫gpt找给我看的 有问题去还请洽询专业医森 --
