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 not only illustrate the suitability of ECHO Cohort data for these purposes but also determine how various definitions of rural and urban populations impact the presentation of findings and their interpretation.

Article Synopsis
  • The study investigates how prenatal dietary quality, assessed through the Healthy Eating Index (HEI) and Empirical Dietary Inflammatory Pattern (EDIP), impacts infant sizes at birth and growth patterns up to age 24 months.
  • Researchers analyzed data from 2854 parent-child pairs participating in a long-term health program, highlighting the diverse racial and ethnic backgrounds of the participants.
  • Results revealed that a healthier diet during pregnancy (high HEI score) is linked to lower likelihoods of having large infants at birth and experiencing rapid growth, suggesting that dietary choices may play a vital role in combating obesity later in life.

Purpose Of Review: Clearly defining and measuring neighborhood socioeconomic status (nSES) is a key first step in achieving environmental justice, as the disproportionate distribution of environmental hazards and access to resources is heavily influenced by socioeconomic factors. This scoping review explores the definition of neighborhoods, measurement of neighborhood socioeconomic status (nSES), and studies that evaluated the association between nSES and child health in accordance with PRISMA guidelines.

Recent Findings: We identified 4112 articles published on US pediatric populations between 2013 and 2022.

  • The study examines the link between breastfeeding practices and child BMI (body mass index) in relation to mothers' BMI, particularly focusing on women with obesity.* -
  • Data from 8,134 mother-child pairs showed that longer breastfeeding duration was associated with lower child BMIz scores across all maternal BMI categories (underweight, healthy weight, overweight, obese).* -
  • The findings suggest that breastfeeding may serve as an effective strategy to reduce the risk of obesity in children, regardless of the mother's BMI status.*

Background: Drinking water is a common source of exposure to inorganic arsenic. In the US, the Safe Drinking Water Act (SDWA) was enacted to protect consumers from exposure to contaminants, including arsenic, in public water systems (PWS). The reproductive effects of preconception and prenatal arsenic exposure in regions with low to moderate arsenic concentrations are not well understood.

Article Synopsis
  • The prevalence of obesity among US youths aged 2 to 19 was 19.3% from 2017 to 2018, and previous studies linked school lunches to increased obesity rates, prompting the Healthy, Hunger-Free Kids Act of 2010 (HHFKA) to enhance nutritional standards for school meals.
  • This study aimed to assess the impact of the HHFKA on youth body mass index (BMI) by analyzing data from a national cohort of children aged 5 to 18 over a period from January 2005 to March 2020.
  • Results indicated that after the HHFKA's implementation, there was a significant decrease in annual BMI z-scores, particularly among youths aged 12 to

Opioid use has disproportionally impacted pregnant people and their fetuses. Previous studies describing opioid use among pregnant people are limited by geographic location, type of medical coverage, and small sample size. We described characteristics of a large, diverse group of pregnant people who were enrolled in the Environmental Influences on Child Health Outcomes (ECHO) Program, and determined which characteristics were associated with opioid use during pregnancy.

In the United States, racial/ethnic minoritized groups experience worse sleep than non-Hispanic Whites (nHW), but less is known about pregnant people. This is a key consideration since poor sleep during pregnancy is common and associated with increased risk of adverse perinatal outcomes. This study reports the prevalence of subjective sleep measures in a multi-racial/ethnic pregnant population from the Environmental influences on Child Health Outcomes (ECHO) program.

Given the diversity of sex, gender identity, race, ethnicity, and socioeconomic position (SEP) in children across the United States, it is incumbent upon pediatric and epidemiologic researchers to conduct their work in ways that promote inclusivity, understanding and reduction in inequities. Current child health research often utilizes an approach of "convenience" in how data related to these constructs are collected, categorized, and included in models; the field needs to be more systematic and thoughtful in its approach to understand how sociodemographics affect child health. We offer suggestions for improving the discourse around sex, gender identity, race, ethnicity, and SEP in child health research.

Introduction: Children at highest obesity risk include those from certain racial/ethnic groups, from low-income families, with disabilities, or living in high-risk communities. However, a 2013 review of the National Collaborative for Childhood Obesity Research Measures Registry identified few measures focused on children at highest obesity risk. The objective is to (1) identify individual and environmental measures of diet and physical activity added to the Measures Registry since 2013 used among high-risk populations or settings and (2) describe methods for their development, adaptation, or validation.

Purpose: Credit scores may operate as a socioeconomic indicator of health: they represent cumulative financial history that directly influences ability to access financial and nonfinancial resources related to health. Yet, little is known about the relationship of credit score and health or to traditional measures of socioeconomic position (SEP). Our objectives were to (1) evaluate the association between area-level credit score and individual self-rated health and (2) compare credit score to traditional markers of area-level SEP in predicting self-rated health.
