Description

Huili Qian and others study how weight before pregnancy shapes newborn results after assisted reproduction in a 2026 paper. The team reviewed 994 mothers who had single babies through assisted reproductive technology and delivered between mid 2020 and mid 2024. Mothers were grouped as thin, normal weight, heavy, or obese by pre-pregnancy body mass index.

Thin mothers faced about four times the adjusted odds of a small-for-gestational-age baby compared with normal-weight mothers. Heavy and obese mothers faced sharply higher odds of large babies and macrosomia. When pregnancy weight gain was adequate, the thin link to small babies persisted, while heavy links faded. The work supports weight counselling before fertility treatment.
