Pre-pregnancy exposure to arsenic in diet and non-cardiac birth defects
Objectives: To explore associations between maternal pre-pregnancy exposure to arsenic in diet and non-cardiac birth defects. Design: This is a population-based, case–control study using maternal responses to a dietary assessment and published arsenic concentration estimates in food items to calculate average daily total and inorganic arsenic exposure during the year before pregnancy. Assigning tertiles of total and inorganic arsenic exposure, lo…
Prenatal Exposure to Tobacco and Childhood Cognition and Behavior
In this exploratory analysis, we assessed whether nutrition modified the association between prenatal exposure to tobacco and childhood cognition/behavior among 366 Colorado-based mothers and their offspring (born ≥ 37 weeks with birthweights ≥ 2500 g). Interaction by folate ( 5 months, but not for shorter durations. Our findings support the need for smoking cessation campaigns throughout pregnancy and throughout the postpartum period breastfeedi…
A Comprehensive Assessment of the Associations Between Season of Conception and Birth Defects, Texas, 1999–2015
Birth defects prevalence may vary seasonally, but previous studies have focused on a few commonly occurring phenotypes. We performed a phenome-wide association study (PheWAS) in order to evaluate the associations between season of conception and a broad range of birth defects. Date of conception was estimated for all livebirths and birth defect cases in Texas from 1999-2015 using data from vital records, provided by the Texas Department of State …
Hypospadias Risk from Maternal Residential Exposure to Heavy Metal Hazardous Air Pollutants
Objective : Investigate whether residential prenatal exposure to heavy metal hazardous air pollutants (HMHAPs) is associated with an increased risk of hypospadias. Methods: Data on non-syndromic hypospadias cases ( n = 8981) and control patients delivered in Texas were obtained from the Texas Birth Defects Registry and matched 1:10 by birth year. Average exposure concentrations of HMHAPs were obtained from the 2005 U.S. Environmental Protection A…
Estimated Maternal Pesticide Exposure from Drinking Water and Heart Defects in Offspring
Our objective was to examine the relationship between estimated maternal exposure to pesticides in public drinking water and the risk of congenital heart defects (CHD). We used mixed-effects logistic regression to analyze data from 18,291 nonsyndromic cases with heart defects from the Texas Birth Defects Registry and 4414 randomly-selected controls delivered in Texas from 1999 through 2005. Water district-level pesticide exposure was estimated by…
Residential Radon Exposure and Incidence of Childhood Lymphoma in Texas, 1995–2011
There is warranted interest in assessing the association between residential radon exposure and the risk of childhood cancer. We sought to evaluate the association between residential radon exposure and the incidence of childhood lymphoma in Texas. The Texas Cancer Registry (n = 2147) provided case information for the period 1995-2011. Denominator data were obtained from the United States Census. Regional arithmetic mean radon concentrations were…
Neighborhood-Based Socioeconomic Position and Risk of Oral Clefts Among Offspring
Objectives. We determined the association between maternal neighborhood socioeconomic position (SEP) and the risk of cleft lip with or without cleft palate (CL±P) or cleft palate alone (CP) in offspring. Methods. We obtained information on CL±P (n = 2555) and CP (n = 1112) cases and unaffected controls (n = 14 735) among infants delivered during 1999 to 2008 from the Texas Birth Defects Registry. Neighborhood SEP variables, drawn from the 2000 US…
Seasonality in birth defects, agricultural production and urban location
Maternal Residential Atrazine Exposure and Gastroschisis by Maternal Age
Occurrence of Conotruncal Heart Birth Defects in Texas
PURPOSE: (1) Determine if there is an association between 3 conotruncal heart birth defects and urban/rural residence of mother. (2) Compare results using different methods of measuring urban/rural status. METHODS: Data were taken from the Texas Birth Defects Registry, 1999-2003. Poisson regression was used to compare crude and adjusted birth prevalence. FINDINGS: Based on residences of births in Texas, the values for urban influence code (UIC), …
Urban–rural residence and the occurrence of neural tube defects in Texas, 1999–2003
Validity of parental work information on the birth certificate
Sensitivity of occupation/industry information on birth certificates varies although the specificity of such information may exceed 95%. Quality of this information also varies by maternal and paternal occupation with misclassification as homemaker a limiting factor among maternal and missing information a limiting factor among paternal work information
