2 Examine maternal and child predictors of cognitive development in 12, 24, and 36 month old children enrolled in the CANDLE Study being conducted by a cross-disciplinary, cross-institutional team of researchers.

3 The CANDLE Study (Conditions Affecting Neurocognitive Development and Learning in Early Childhood) is designed to:  Evaluate 1,500 pregnant women and their children living in Memphis/Shelby County, TN from the second trimester into childhood.  Investigate the wide range of genetic, epigenetic, demographic, environmental and social factors influencing child development across urban and suburban neighborhoods.

4 Pregnant women between 16 and 28 weeks gestation Shelby County resident Low risk pregnancy Between the ages of 16 and 40 Speak and understand English Single pregnancy Must be willing to give consent

12 Observed cognitive growth fostering behavior measured by the Teaching Scale contributed to cognitive development in 12, 24, and 36 month olds. The variables making the greatest contribution to the young child’s development varied across these three time points. Additionally, maternal characteristics, i.e., education, socioeconomic status, and race, varied at each time point.

13 Factors contributing to maternal behaviors that foster child development should be examined carefully. As the CANDLE Study data collection continues, statistical analyses can be conducted to identify groups within this population that can benefit from interventions that are tailored to maternal and child characteristics and available resources to the children, their mothers, and their families.
