Association between maternal exposure to atole in comparison with fresco for mothers born between 1962 and 1977 in Guatemala and anthropometric measures of male and female offspring in 2006–2007¹

¹Mothers were supplemented as children in the 1969–1977 study; the offspring were aged 0–12 y in the 2006–2007 study. Exposure to atole, the more-nutritious supplement, is a dummy variable that equals 1 for children born to mothers exposed to atole when aged <15 y. Offspring of mothers exposed to fresco, the less-nutritious supplement, constitutes the reference group. P values and 95% CIs were calculated allowing for clustering at the mother level. Additional variables included but not reported are offspring sex, a second-order polynomial in child age, and a variable for mother's date of birth.

²Weight-for-age z score covers up to age 120 completed months; thus, n = 306 boys and 315 girls.
