A new study of 6550 women found that women with postpartum depression or general depression are 50% more likely to have shorter kids. Pamela J. Surkan, the lead researcher, states that
we hypothesize that the main link between maternal postpartum symptoms of depression and child height is through care-giving behaviors, perhaps by means of feeding practices or through these mothers’ reduced abilities to get help for their sick children when they are sick.
Although the variables are numerous, the correlation remains that depression in women before and during motherhood can lead to stunted growth in their children.
Ongoing research regarding this correlation has consistently found similar or identical results.
