UNM researcher finds stress during pregnancy affects the size of the baby

(University of New Mexico) A new study has been published that suggests babies are physically affected by the stress level of their mother during pregnancy. "We found that stress during late gestation reduces offspring growth during dependence, resulting in a reduced body size throughout development, whereas stress during early gestation results in largely unaffected growth rates during dependence but accelerated growth and increased size after weaning," says Andreas Berghänel, evolutionary anthropologist at UNM and lead author of the study.
