There have been a few studies suggesting an association between maternal obesity and a child’s neurodevelopment but none that have looked at both maternal and paternal obesity and whether their influence on childhood development is the same or different. At least until now—when Yeung et al. ( 10.1542/peds.2016-1459) studied mothers and paternal partners in a longitudinal cohort made up of upstate New York families enrolled at 4 months postpartum and then surveyed at four to six-month intervals until children were 3 years of age using the Ages and Stages Questionnaire to assess development in various areas (e.g. gross and fine motor, language, and social skills).
