Are gestational diabetes mellitus and preconception diabetes mellitus less common in non-Hispanic black women than in non-Hispanic white women?

Based on their higher risk of type 2 diabetes, non-Hispanic blacks (NHBs) would be expected to have higher gestational diabetes mellitus (GDM) risk compared to non-Hispanic whites (NHWs). However, previous studies have reported lower GDM risk in NHBs versus NHWs. We examined whether GDM risk was lower in NHBs and NHWs, and whether this disparity differed by age group.

Creation and evaluation of a multi-layered maternal and child health database for comparative effectiveness research.

Background: As high-speed computers and sophisticated software packages for data linkage become increasingly available, investigators from nearly every arena are creating massive databases for epidemiologic and comparative effectiveness research (CER). Decisions made during database construction have a major impact on the accuracy and completeness of the data. Considering their potential use in informing health-care decisions, it is vital that we increase transparency of these data, including a thorough understanding of the record linkage strategy implemented and an evaluation of linked and unlinked records so that potential biases can be addressed.

A Systematic Review of Quality of Life Measures in Pregnant and Postpartum Mothers.

Quality of life has emerged as an essential health component that broadens the traditionally narrow concerns focused on only morbidity and life expectancy. Although a growing number of tools to measure quality of life are in circulation, there is a lack of guidelines as well as rigorous assessment for their use with pregnant and postpartum populations. It is also unclear whether these instruments could validly be employed to measure patient-reported outcomes in comparative effectiveness research of maternal care interventions.

Cutting-edge technology for public health workforce training in comparative effectiveness research.

A critical mass of public health practitioners with expertise in analytic techniques and best practices in comparative effectiveness research is needed to fuel informed decisions and improve the quality of health care. The purpose of this case study is to describe the development and formative evaluation of a technology-enhanced comparative effectiveness research learning curriculum and to assess its potential utility to improve core comparative effectiveness research competencies among the public health workforce. Selected public health experts formed a multidisciplinary research collaborative and participated in the development and evaluation of a blended 15-week comprehensive e-comparative effectiveness research training program, which incorporated an array of health informatics technologies.

Low-level exposure to air pollution and risk of adverse birth outcomes in Hillsborough County, Florida.

Objective: In this retrospective cohort (1998 to 2007), 145,445 singleton live births in Hillsborough, Florida, were analyzed to elucidate the relationship between fetal morbidity and prenatal exposure to six criteria air pollutants.

Methods: This study was based on three linked databases: Florida Hospital Discharge, vital statistics records, and air pollution meteorological data from the Environmental Protection Agency. The primary outcomes of interest were low birth weight, preterm births, and small for gestational age.

Exposure to environmental tobacco smoke and risk of antenatal depression: application of latent variable modeling.

This study sought to determine the impact of passive smoking on the risk for depressive symptoms during pregnancy. In this prospective study, 236 pregnant women were recruited at less than 20 weeks of gestation from a university-affiliated obstetric clinic from November 2009 through July 2011. Tobacco use/exposure was measured using questionnaire and confirmed by salivary cotinine analysis.

Obligatory versus elective single embryo transfer in in vitro fertilization. A population-based analysis of data from the U.K. Human Fertilisation and Embryology Authority.

Objective: To determine how obligatory single embryo transfer (SET) and elective SET influence pregnancy outcome.

Study Design: We compared women who underwent obligatory and elective SET using data from a comprehensive, population-based register from the United Kingdom Human Fertilisation and Embryology Authority, which contained all in vitro fertilization (IVF) treatments administered between 1991 and 1998. Generalized estimating equations were used to generate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) to compare clinical pregnancy, live birth, and multiple birth rates.

Early childhood lead exposure and academic achievement: evidence from Detroit public schools, 2008-2010.

Objectives: We assessed the long-term effect of early childhood lead exposure on academic achievement in mathematics, science, and reading among elementary and junior high school children.

Methods: We linked early childhood blood lead testing surveillance data from the Detroit Department of Health and Wellness Promotion to educational testing data from the Detroit, Michigan, public schools. We used the linked data to investigate the effect of early childhood lead exposure on academic achievement among school-aged children, both marginally and adjusted for grade level, gender, race, language, maternal education, and socioeconomic status.

Association between reproductive cancer and fetal outcomes: a population-based study.

Purpose: This study aimed to evaluate the impact of maternal reproductive cancer diagnosis on fetal birth outcomes.

Materials And Methods: We conducted a retrospective population-based cohort study among women with a singleton live birth and diagnosed with reproductive cancer in the state of Florida (cases). We matched cases to cancer-free controls using selected sociodemographic and pregnancy-related clinical conditions.

Obesity, assisted reproductive technology, and early preterm birth--Florida, 2004-2006.

Florida resident birth certificates for 2004-2006 were linked to the Centers for Disease Control and Prevention's National ART Surveillance System and were used to investigate 1) whether the association of assisted reproductive technology (ART) with preterm birth varies by prepregnancy body mass index and 2) whether the association varies by plurality. Preterm birth was defined as early preterm birth (gestation <34 weeks) and late preterm birth (gestation 34-36 weeks). Descriptive statistics and multinomial logistic regression were used to explore maternal and infant differences by ART status and plurality.

HIV infection and its impact on fetal outcomes among women of advanced maternal age: a propensity score weighted matching approach.

Advanced maternal age (AMA) and HIV status have been investigated separately for their influence on infant outcomes. Both are associated with adverse fetal growth outcomes, including low birth weight (LBW) and preterm birth (PTB). However, the impact of the cooccurrence of these factors in relation to birth outcomes remains relatively understudied.

Systematic review on sleep disorders and obstetric outcomes: scope of current knowledge.

Objective: To assess the current state of knowledge regarding sleep disorders and their relationship to obstetric outcomes.

Study Design: A systematic literature review of the previous two decades (1991 to 2010) was conducted. The exposure was sleep disorders during pregnancy, and the outcomes of interest were feto-infant morbidity and maternal complications.

Male circumcision and HIV risk behavior among university students in northern Nigeria.

Recent trials demonstrate the effectiveness of male circumcision (MC) in reducing HIV acquisition in men. However, little is known about the prevalence and acceptability of the practice in northern Nigeria. A cross-sectional study design was employed to explore knowledge and attitudes to MC among university students in Kano, Nigeria (n = 375).

Purpose: To examine the association between small for gestational age (SGA) in the first pregnancy and risk for infant mortality in the second pregnancy.

Methods: This is a population-based, retrospective cohort study in which we used the Missouri maternally linked cohort dataset for 1978-2005. Analyses were restricted to women who had two singleton pregnancies during the study period.

Infant mortality and the risk of small size for gestational age in the subsequent pregnancy: a retrospective cohort study.

To examine the association between prior infant mortality and subsequent risk for small for gestational age (SGA). This population-based, retrospective cohort study used the Missouri maternally linked, longitudinal dataset (1989-2005). Analyses were restricted to women who had two singleton pregnancies during the study period.

Twins born over weekends: are they at risk for elevated infant mortality?

Objective: To assess the impact of the day of birth on twin mortality in a population sample.

Methods: We analyzed weekend versus weekday twin births from the United States national twin birth data for the periods 1989-2002. We computed adjusted hazard ratios (HR) and 95% confidence intervals (CI) to assess the association between infant mortality and weekday of birth using the Cox proportional hazards model.

The missing link in preconceptional care: the role of comparative effectiveness research.

This paper discusses an important element that is missing from the existing algorithm of preconception care, namely, comparative effectiveness research (CER). To our knowledge, there has been limited assessment of the comparative effectiveness of diverse interventions that promote preconception health, conditions under which these are most effective, for which particular populations, and their comparative costs. CER can improve the decision making process for the funding, development, implementation, and evaluation of comprehensive preconception care programs, specifically by identifying the most effective interventions with acceptable costs to society.

The association between HIV/AIDS during pregnancy and fetal growth parameters in Florida: a population based study.

In this population-based retrospective study, we sought to investigate the association between HIV/AIDS during pregnancy and adverse birth outcomes, including low birth weight (LBW), very low birth weight (VLBW), preterm birth (PTB), very preterm birth (VPTB), and small for gestational age (SGA), among women in Florida by sociodemographic variables. Using data from Florida's maternally linked birth cohort files, we examined singleton live births in the state during 1998 to 2007 (N = 1,698,107). The study population was categorized based on the maternal HIV/AIDS status.

The Florida Investigation of Primary Late Preterm and Cesarean Delivery: the accuracy of the birth certificate and hospital discharge records.

(1) Assess the accuracy of public health data sources used to investigate primary late preterm cesarean delivery (PLPCD) and (2) compare differences in data accuracy by hospital PLPCD rate classification. This analysis uses data from the Florida Investigation of Late Preterm and Cesarean Delivery (FILPCD), an investigation of singleton, PLPCD's that occurred from 2006 to 2007 in hospitals classified with either a low or high PLPCD rate (high rate 39.4-58.

Prevalence and correlates of gender-based violence among female university students in Northern Nigeria.

Gender-based violence (GBV) is a major public health and human rights problem worldwide. The extent of this problem in educational institutions has not been explored in Northern Nigeria. Using self administered questionnaires, we determined the prevalence and risk factors for gender-based violence among 300 female university students in Kano, Northern Nigeria.

Cigarette smoking and fetal morbidity outcomes in a large cohort of HIV-infected mothers.

Background: Reproductive-age women comprise approximately 25% of all persons living with HIV/AIDS in the United States. HIV infection and smoking during pregnancy are independent risk factors for adverse fetal outcomes. We examined predictors of fetal growth restriction among infants born to HIV-infected mothers who smoke cigarettes in pregnancy.

The effect of paternal age on fetal birth outcomes.

Research investigating the role of paternal age in adverse birth outcomes is limited. This population-based retrospective cohort study used the Missouri maternally linked data set from 1989 to 2005 to assess whether paternal age affects fetal birth outcomes: low birth weight (LBW), preterm birth (PTB), stillbirth, and small size for gestational age (SGA). We examined these outcomes among infants across seven paternal age-groups (<20, 20-24, 25-29, 30-34, 35-39, 40-45, and >45 years) using the generalized estimating equation framework.

Racial/ethnic differences in the percentage of gestational diabetes mellitus cases attributable to overweight and obesity, Florida, 2004-2007.

Introduction: Gestational diabetes mellitus (GDM) affects 3% to 7% of pregnant women in the United States, and Asian, black, American Indian, and Hispanic women are at increased risk. Florida, the fourth most populous US state, has a high level of racial/ethnic diversity, providing the opportunity to examine variations in the contribution of maternal body mass index (BMI) status to GDM risk. The objective of this study was to estimate the race/ethnicity-specific percentage of GDM attributable to overweight and obesity in Florida.
