Study Background
CREW shares data from participating birth cohorts to build a central data set to study the relationship between childhood asthma and early environmental factors that may cause childhood asthma. To accomplish these goals, the scientific information and resources from the 12 birth cohorts will be combined, and researchers and biostatisticians will work collaboratively to analyze data that already have been collected among a diverse sample of US children to better understand the underlying causes of childhood asthma.
CREW02
This research project studies the relationship between childhood asthma and early-life environmental factors that may cause the disease. Previous birth cohort studies have found early-life environmental factors such as allergens, pollutants, viruses and bacteria have all contributed to the development of asthma. We are doing this research because there continues to be a strong need to understand the root causes of asthma.
ECHO
Environmental Influences on Child Health Outcomes (ECHO) is a nationwide program to help understand how the environment and things that happen early in children’s lives—even before they are born—affect their development, health, and well-being. The environment includes: the air they breathe, foods they eat, interactions with other people, and the neighborhoods where they live. Looking at differences in genes, which are made of DNA, can help us learn how genes and the environment work together to affect children’s growth, development, and health before and after birth, throughout childhood, and into adulthood. Genes may affect how our bodies respond to the environment, and the environment may affect how our genes work.
