Children' genotypes were not related to potential confounders including maternal social class, maternal education level, reproductive outcomes, diet intakes, or maternal tobacco and alcohol consumption during pregnancy.
Six socioeconomic variables were obtained from the above assessments; quality of the home environment (MC-HOME score), nutritional status, maternal education level, child's education level and socioeconomic status (SES) score.
*Adjusted for pubertal development and maternal education level.
Urban/rural setting and maternal education level were not significant.
Model 1: model 0 +adjusted for maternal education level.
Maternal education level and maternal age were significantly intercorrelated (r = 0.217, p = 0.008), but maternal education level was the more significant contributor to neurodevelopmental outcomes.
In the Within-family models the covariate maternal education level is omitted.
The effect of maternal education level was stronger than husband's education.
Maternal and paternal education co-varied and, hence, maternal education level was used alone.
Ethnicity, maternal education level and smoking during pregnancy were assessed through questionnaires.
The inverse association between maternal education level and initiation of HPV vaccination is also interesting.
