Psychological disorders impacting body weight, such as anorexia nervosa, bulimia, binge eating disorder, and compulsive overeating, can cause health-related complications for women and their fetuses if they become pregnant. Insufficient or excessive gestational weight gain has been shown to contribute to adverse fetal outcomes and delivery complications. The Apgar score is a universal method used to assess infant health upon delivery. This research study correlated the 1-minute Apgar scores of infants, with the amount of gestational weight gained (classified as normal, insufficient or excessive based on Institute of Medicine guidelines). Results did not support the hypothesis that insufficient or excessive weight gain would be related to lower Apgar scores. There was sufficient evidence to substantiate a strong correlation between pre-pregnancy weight and body mass index in relation to gestational weight gain. Various limitations and suggestions for future research are discussed.
