Data regarding maternal characteristics, psychiatric diagnoses, psychotropic medication use including polypharmacy and metabolically high\u2010risk psychotropic medications, and obstetric outcomes were extracted from medical records. Infants were classified as LGA or SGA according to gestational age\u2010specific birth weight standards. Multivariable logistic regression analyses were performed to identify independent factors associated with LGA and SGA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of the 400 pregnancies, 40 infants were classified as LGA and 40 as SGA. Psychotropic medication use, including polypharmacy and metabolically high\u2010risk psychotropic medications, was not independently associated with either LGA or SGA. For LGA, only high prepregnancy BMI was identified as an independent risk factor. For SGA, hypertensive disorders of pregnancy, maternal alcohol consumption, and lower prepregnancy BMI were independently associated with increased risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In pregnancies complicated by psychiatric disorders, fetal growth abnormalities were primarily associated with maternal background factors.
