In a study investigating links between parental smoking during pregnancy and high blood pressure in adult daughters, maternal and paternal smoking during pregnancy (> 15 cigarettes per day) was associated with increased rates of hypertension.
Adjusting for birth weight had little effect, but adjusting for body shape and weight up to age 18 years or for current body mass index did.
The authors say that these links are largely explained by body weight throughout life rather than direct intrauterine mechanism involving smoking.
