Please read Dr. Reichman’s article in the Maternal and Child Health Journal titled, “Small-for-Gestational-Age and Vocabulary and Achievement Test Scores at Age 9 Among Children Born at Term in a Contemporary U.S. Sample.“
Numerous studies have demonstrated links between lower birth weight (BW) or small-for-gestational-age (SGA) and cognitive impairments among individuals born preterm (< 37 completed weeks of gestation), highlighting that group as particularly vulnerable. Associations between SGA and cognitive impairments have also been found among individuals born at term (generally defined as 37–41 completed weeks), but that literature consists of a small patchwork of studies from different countries, populations, and birth cohorts, and focused on different ages of children. SGA is typically defined as below the 10th (or sometimes 5th) percentile of BW for the number of weeks of gestation in a given population. Most studies use sex-specific reference distributions of BW-for-age. To read the full article.
