growth in the mother. The primary objective of this study is to exam-ine the effect on final adult height of women whose first live birthoccurred prior to the age of 18 compared to women whose first livebirth was at age 18 or older.STUDY DESIGN: This retrospective cohort study used data from theNational Health and Nutrition Examination Survey (NHANES). Wecombined three 2-year cycles of the continuous NHANES database,from 1999-2004, and studied women ages 18-50 years who had at leastone live birth. Statistical analyses were carried out using SAS surveyprocedures which take into account the sampling weights and com-plex study design for calculating variance estimates. Comparisons ofadult height between mothers reporting at least one live birth duringadolescence (age �18 years) and mothers whose first live birth oc-curred as an adult (age �18 years) were performed using regressionanalysis.RESULTS: A total of 2584 women were included in the study. Womenwho gave birth in adolescence were approximately 1.05 cm shorter infinal adult height than women who gave birth to their first child at �18 years (p�0.03). There was no interaction of group (age at first birthstatus of �18 or �18) and ethnicity or group and gynecologic age.CONCLUSION: Adult women who had their first live birth prior to age18 have reduced height compared to women who had their first livebirth at age 18 or older. Although the reduction in adult height afteradolescent pregnancy is clinically small, further research is required todetermine its cause, as well as other potential consequences of mater-nal/fetal competition for resources and growth.

676 Violence against women increases the riskof gestational hypertensive disordersMatthew Garabedian1, Corrine Williams2, Molly Strong2,Lisandra Garcia2, Wendy Hansen2, Ann Coker2

1University of Kentucky, Ob-Gyn, Lexington, KY, 2Universityof Kentucky, Obstetrics & Gynecology, Lexington, KYOBJECTIVE: We investigated the association between lifetime historyof violence against women (VAW) and gestational hypertensive dis-orders (gestational hypertension and preeclampsia). We hypothe-sized that VAW would be associated with an increased in risk of ges-tational hypertensive disorders.STUDY DESIGN: Universal psychosocial screening, including screeningfor lifetime VAW (physical, sexual, psychological), was implementedfor those enrolling for obstetric care at the University of Kentucky(UK). A cohort of 479 women from prenatal care clinics, enrolling incare from 8/1/08 to 12/31/09, was followed. Data were extracted fromthe medical record. Statistical analysis included �2, simple binomialregression and multivariate binomial regression analyses.RESULTS: Of 479 women enrolled, 425 (89%) delivered at UK. Life-time VAW was reported by 65 (14%) women, with 27 (42%) havingexperienced multiple forms. Gestational hypertensive disorders weremore common among women with a history of VAW (26%) thanamong women without a history of VAW (13%; RR 2.0, 95% CI1.33.3). This remained true after controlling for parity, race/ethnicity,gestational age, and smoking (RR 2.0, 95% CI 1.23.4). Controlling forthe same factors, the relative risk for having experienced multipleforms of VAW was greater than having experienced a single form(Table). Lifetime history of VAW was more strongly associated withgestational hypertensive disorders among women with obesity (�2�6.9, P�.01) than among the non-obese (�2 �.4, P�.5). Amongwomen with obesity, a lifetime history of multiple forms of VAW wasstrongly associated with gestational hypertensive disorders (adjustedRR 4.3, 95% CI 2.67.2).CONCLUSION: Lifetime VAW is associated with gestational hyperten-sive disorders. The association between VAW and gestational hyper-tensive disorders is strongest among women with obesity. This risk isgreater for women experiencing multiple forms. Our findings high-light the need to screen patients for abuse, as this may impact preg-nancy outcomes.

Between 3-19% ofpregnant women experience IPV. IPV during pregnancy has been asso-ciated with preterm birth, low birth weight, placental abruption and neo-natal injury and death. Children born to mothers who are victims of IPVare more likely to suffer from child abuse. Our objective was to comparematernal and neonatal outcomes of pregnant women who were victimsof IPV to women of similar socioeconomic status who denied IPV.STUDY DESIGN: Using our electronic medical record, charts of womenwho were pregnant between March 2009 and April 2010 were reviewed.The study had received IRB review prior to initiation. All women whoreceive prenatal care at our center undergo screening for IPV. Thosewomen who reported violence became our study group (N�73).Women who delivered within 7 days of a study subject and who deniedIPV served as the control group (N � 71). Univariate analyses were per-formed. A p value less than 0.05 was considered significant.RESULTS: The two groups were similar in their demographic values such asethnicity, marital status, and if the subject were employed. Mothers who re-ported IPV were more likey to have a positve drug screen (57% vs 28% incontrols p�0.01), and had a lower mean gestational age at delivery (35.5weeks vs 37.7 weeks p�0.001). Infants born to mothers who reported IPVduring pregnancy had lower mean birth weight (2883g versus 3066gp�0.035). The IPV mothers also had less prenatal visits (7.2 versus 8.9p�0.05).Anon-significantincreaseincesareandeliverywasnotedintheIPVgroup (p�0.051).CONCLUSION: IPV is a common problem faced by pregnant women in theUnited States. It contributes to such neonatal complications as low birthweightandpretermbirth.Universal screeningandearly interventioninthesedifficult situations is recommended. Further research to study if such inter-ventions reduce the aforementioned complications is needed.
