CPM, colored progressive matrices. *n = 94–100. ^†Range of values for independent variables: mother's education 0–6; household latrine availability 0–1; and BMI 15.2–29.0 kg m⁻². ^‡Variables tested in the stepwise model were: mothers' education, husbands' education, household latrine availability and mothers' body mass index. All variables that entered the model with a P‐value < 0.1 are shown in the table.
