“…First, most previous studies have been conducted in developed countries where the definition of home environment differs from that in developing countries and, second, from the measures used in this study. We know that in developed countries the home environment is measured by structural and status indexes such as parental education, occupation, income, size of family, type of dwelling, and processes within a child's environment (Caldwell & Bradley 1984;Coons et al, 1982;Entwisle & Astone, 1994;Iverson & Walberg, 1982;Mishra 1989).
