Low-income preschoolers exposed to nurturing care have with higher IQ scores later on

Preschoolers living in impoverished communities who have access to a nurturing home environment have significantly higher intelligence quotient (IQ) scores in adolescence compared to those raised without nurturing care. That is the finding of a new international study conducted by University of Maryland School of Medicine (UMSOM) researchers, which examined data from more than 1600 children from Brazil and South Africa who were followed from birth through their teenage years. Results were published this week in The Lancet Child & Adolescent Health journal.
