OBJECTIVES We examined associations between obesity, diabetes, and 3 adverse pregnancy outcomes--primary cesarean delivery, preterm birth, and low birth-weight (LBW)--by racial/ethnic group. Our goal was to better understand how these associations differentially impact birth outcomes by group in order to develop more focused interventions. METHODS Data(More)
OBJECTIVE To examine the association between route of delivery and neonatal outcomes in a large, diverse cohort of preterm, appropriate-for-gestational-age neonates. METHODS This is a retrospective cohort study examining New York City birth data for 1995-2003 linked to hospital discharge data. Data were limited to singleton, live-born, cephalic neonates(More)
OBJECTIVE To evaluate the effects of the September 11, 2001, World Trade Center attacks on birth outcomes. METHODS Live singleton births between September 11, 2001, and October 31, 2002, to women enrolled in a World Trade Center Health Registry (the Registry, n=446) were compared with births to women residing more than 5 miles from the World Trade Center(More)
Prospective, multiyear epidemiologic studies have proven to be highly effective in discovering preventable risk factors for chronic disease. Investigations such as the Framingham Heart Study have produced blueprints for disease prevention and saved millions of lives and billions of dollars. To discover preventable environmental risk factors for disease in(More)
Although pregnancy events predict the long-term risk of chronic disease, little is known about their short-term impact because of the rarity of clinical events. We examined hospital discharge diagnoses linked to birth certificate data in the year following delivery for 849,639 births during 1995-2004 in New York City, New York. Adjusted odds ratios(More)
OBJECTIVE To estimate the risks for medically attended events occurring within 42 days of receiving trivalent inactivated influenza vaccine and to evaluate specific risks of first-trimester vaccination. METHODS This retrospective observational cohort study compared rates of medically attended adverse events in trivalent inactivated influenza-vaccinated(More)
INTRODUCTION Since October 2012, the combined tetanus toxoid, reduced diphtheria toxoid, acellular pertussis vaccine (Tdap) has been recommended in the United States during every pregnancy. METHODS In this observational study from the Vaccine Safety Datalink, we describe receipt of Tdap during pregnancy among insured women with live births across seven(More)
OBJECTIVE To compare neonatal outcomes by method of delivery in preterm (34 weeks of gestation or prior), small-for-gestational-age (SGA) newborns in a large diverse cohort. METHODS Birth data for 1995-2003 from New York City were linked to hospital discharge data. Data were limited to singleton, liveborn, vertex neonates delivered between 25 and 34 weeks(More)
We sought to determine if advanced maternal age (AMA) is a risk factor for intrauterine fetal demise (IUFD). We used a U.S. Centers for Disease Control and Prevention database and analyzed outcomes in women 15 to 44 years of age with term singleton gestations. Cox proportional hazards models and Cochran-Mantel-Haenszel tests were used. Results were(More)
OBJECTIVE To compare neonatal neurologic complication rates of cesarean deliveries, forceps-assisted vaginal deliveries, and vacuum-assisted vaginal deliveries. METHODS Data on singleton live births at 34 weeks or greater gestation born to nulliparous women from 1995 to 2003 in New York City were linked to hospital discharge data. Any diagnosis of(More)
