| Study Title | The ECHO Cohort Exposome: First Steps using HHEAR Analysis – An Opportunity for ALL ECHO Cohorts to Contribute Type A Samples – Untargeted Analysis (CANDLE Cohort) |
| Study Type | Prospective Cohort Study |
| Study Summary | The CANDLE study is a contemporary birth cohort representing a racially and socioeconomically diverse southern metropolitan population of the US. It was designed to investigate the effects of different factors, such as prenatal characteristics, home environment, childhood experiences, genetics, and exposure to potentially harmful substances on the neurocognitive development of children from birth to age four years. The CANDLE study enrolled a total of 1,503 healthy women during their 2nd trimester of pregnancy at four hospitals in Memphis, TN. The sample accrued between 2006 and 2011, demographically representing Shelby County TN, a highly disadvantaged urban population. Study participants are primarily African American and White. This research was supported by the Environmental influences on Child Health Outcomes (ECHO) Program, Office of The Director, National Institutes of Health.
