title: Socioeconomic position, maternal IQ, home environment, and cognitive development.
abstract: OBJECTIVE
  To assess whether socioeconomic position, maternal intelligence (IQ), and the home environment are inter-related to cognitive development in childhood.
  
  
  METHODS
  Prospective cohort study (n = 723) with cognitive tests at ages 2, 4, 7, and 11 to 13 years.
  
  
  RESULTS
  There were statistically significant positive associations of father's occupational prestige, Home Observation for Measurement of Environment (HOME) score, and maternal IQ with cognitive performance in childhood. After adjustment for confounding factors, there was an increase in cognitive development by 0.8 to 2.0, 2.9 to 4.8, and 4.2 to 9.0 points for a 10-unit increment in father's occupational prestige, maternal IQ, and HOME score, respectively.
  
  
  CONCLUSIONS
  These results demonstrate that socioeconomic position, maternal IQ, and the home environment are independently and positively predictive of children's cognitive development. These findings provide additional rationale for implementing social policies that reduce socioeconomic inequalities.
