Adjusted model 1 was adjusted for demographic characteristics, family structure and socioeconomic status
Adjusted model 2 was further adjusted for conditions of gestation, delivery and feeding besides the covariates in adjusted model 1
Adjusted model 3 was further adjusted for health problems, daily activity and behavior routine besides the covariates in adjusted model2
