Challenges Associated With Rural‐Urban Stratification for Generalizing Birth Outcomes
PURPOSE: Efforts to generalize findings from the Environmental influences on Child Health Outcomes (ECHO) Cohort across rural and urban areas are challenged by limitations in both sample composition and the classification schemes used to define place. We evaluated how rural-urban stratification affects the interpretation and generalizability of preterm birth (PTB) prevalence proportions in the ECHO Cohort compared to national benchmarks. METHODS:…
A descriptive examination of rurality in the Environmental influences on Child Health Outcomes Cohort
PURPOSE: The Environmental influences on Child Health Outcomes (ECHO) Cohort has enrolled over 60,000 children to examine how early environmental factors (broadly defined) are associated with key child health outcomes. The ECHO Cohort may be well-positioned to contribute to our understanding of rural environments and contexts, which has implications for rural health disparities research. The present study examined the outcome of child obesity to …
Wildfire-specific fine particulate matter and preterm birth
Do small effects matter more in vulnerable populations? an investigation using Environmental influences on Child Health Outcomes (Echo) cohorts
Vulnerable sub-populations with greater baseline percentages at high risk fare worse when exposed to a small insult compared to the general population. This illustrates another facet of health disparity in vulnerable individuals
Demographic and health characteristics associated with fish and n -3 fatty acid supplement intake during pregnancy
Objective: n -3 fatty acid consumption during pregnancy is recommended for optimal pregnancy outcomes and offspring health. We examined characteristics associated with self-reported fish or n -3 supplement intake. Design: Pooled pregnancy cohort studies. Setting: Cohorts participating in the Environmental influences on Child Health Outcomes (ECHO) consortium with births from 1999 to 2020. Participants: A total of 10 800 pregnant women in twenty-t…
Airborne Lead Exposure and Childhood Cognition
Objectives. To examine whether a previously reported association between airborne lead exposure and children’s cognitive function replicates across a geographically diverse sample of the United States. Methods. Residential addresses of children ( Results. An IQR increase in airborne lead was associated with a 0.74-point lower mean IQ score (b = −0.74; 95% confidence interval = −1.00, −0.48). The association between lead and EF was nonlinear and w…
Association of maternal education, neighborhood deprivation, and racial segregation with gestational age at birth by maternal race/ethnicity and United States Census region in the Echo cohorts
Background In the United States, disparities in gestational age at birth by maternal race, ethnicity, and geography are theorized to be related, in part, to differences in individual- and neighborhood-level socioeconomic status (SES). Yet, few studies have examined their combined effects or whether associations vary by maternal race and ethnicity and United States Census region. Methods We assembled data from 34 cohorts in the Environmental influ…
Developing a National-Scale Exposure Index for Combined Environmental Hazards and Social Stressors and Applications to the Environmental Influences on Child Health Outcomes (Echo) Cohort
Tools for assessing multiple exposures across several domains (e.g., physical, chemical, and social) are of growing importance in social and environmental epidemiology because of their value in uncovering disparities and their impact on health outcomes. Here we describe work done within the Environmental influences on Child Health Outcomes (ECHO)-wide Cohort Study to build a combined exposure index. Our index considered both environmental hazards…
Predictors of Breastfeeding Duration in the New Hampshire Birth Cohort Study
Health Behavior Changes during the Covid-19 Pandemic
This longitudinal study compared children’s health behaviors before the COVID-19 pandemic versus during the pandemic. This analysis examined the association between individual-level characteristics and health behavior change. Four prospective cohort studies in the Environmental influences on Child Health Outcomes (ECHO) Program contributed data. Children aged 4−12 years and their caregivers were recruited in California, Colorado, North Dakota, an…
Children’s Particulate Matter Exposure Characterization as Part of the New Hampshire Birth Cohort Study
As part of the New Hampshire Birth Cohort Study, children 3 to 5 years of age participated in a personal PM 2.5 exposure study. This paper characterizes the personal PM 2.5 exposure and protocol compliance measured with a wearable sensor. The MicroPEMTM collected personal continuous and integrated measures of PM 2.5 exposure and compliance data on 272 children. PM 2.5 , black carbon (BC), and brown carbon tobacco smoke (BrC-ETS) exposure was meas…
Assessment of Multipollutant Exposures During Pregnancy Using Silicone Wristbands
Silicone wristbands can assess multipollutant exposures in a non-invasive and minimally burdensome manner, which may be suitable for use among pregnant women. We investigated silicone wristbands as passive environmental samplers in the New Hampshire Birth Cohort Study, a prospective pregnancy cohort. We used wristbands to assess exposure to a broad range of organic chemicals, identified multipollutant exposure profiles using self-organizing maps …
Mapping Disease at an Approximated Individual Level Using Aggregate Data
RCMC is an effective method to disaggregate aggregate data. An RCMC-based disease mapping maximizes the use of available spatial information, and explicitly estimates the spatial uncertainty resulting from aggregation
