推 forsakesheep: 你板人查文獻說35歲以上才有差 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. 這篇說對孕婦本身的風險來看，35歲以上的孕婦短間隔懷孕有明顯風險，20到34歲看不出明 顯風險 本質上是高齡產婦問題 但是對嬰兒早產、體重不足、死胎的風險有提高 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. 這篇則說用三胎的孕婦的資料來看，對於嬰兒的風險可能不適合用單純用短間隔懷孕來認定 。 還要考慮孕婦本人的其他因素。 意思就是某些短期懷孕的孕婦可能會因為個人習慣或社經地位的問題導致胎兒出毛病。 我昨天半夜睡不著叫gpt找給我看的 有問題去還請洽詢專業醫森 --
