Sixteen of the studies were from the USA. Not surprisingly, non-white mothers did much worse. In a meta-analysis of 5 such studies, African American teen mothers had a 67% greater chance of preterm delivery (OR 1.67) or LBW (OR 1.53), compared with white mothers. A broad range of social determinants were consistently associated with higher rates of PTB, LBW and SGA in various studies, including illiteracy, low economic status, and living in rural areas.
