Objectives. We compared an evidence-based model of group prenatal care to traditional individual prenatal care on birth, neonatal, and reproductive health outcomes. Methods. We performed a multisite cluster randomized controlled trial in 14 health centers in New York City (2008–2012). We analyzed 1148 pregnant women aged 14 to 21 years, at less than 24 weeks of gestation, and not at high obstetrical risk. We assessed outcomes via medical records and surveys. Results. In intention-to-treat analyses, women at intervention sites were significantly less likely to have infants small for gestational age (< 10th percentile; 11.0% vs 15.8%; odds ratio = 0.66; 95% confidence interval = 0.44, 0.99). In as-treated analyses, women with more group visits had better outcomes, including small for gestational age, gestational age, birth weight, days in neonatal intensive care unit, rapid repeat pregnancy, condom use, and unprotected sex (P = .030 to < .001). There were no associated risks. Conclusions. CenteringPregnancy Plus group prenatal care resulted in more favorable birth, neonatal, and reproductive outcomes. Successful translation of clinical innovations to enhance care, improve outcomes, and reduce cost requires strategies that facilitate patient adherence and support organizational change.

Background. Racial/ethnic disparities in birth weight persist within the USA.Purpose. The purpose of this study is to examine the association between

Urban teens face many traumas, with implications for potential growth and distress. This study examined traumatic events, posttraumatic growth, and emotional distress over 18 months among urban adolescent girls (N = 328). Objectives were to (a) describe types of traumatic events, (b) determine how type and timing of events relate to profiles of posttraumatic growth, and (c) prospectively examine effects of event type and posttraumatic growth on short- and long-term emotional distress with controls for pre-event distress. Results indicate that type of event was related to profiles of posttraumatic growth, but not with subsequent emotional distress. When baseline emotional distress was controlled, posttraumatic growth was associated with subsequent reductions in short- and long-term emotional distress. Implications for future research and clinical practice with adolescents are addressed.
