All estimates are weighted and adjusted for design effects.

^aAdjusted for child's gender.

^bAdjusted for child's gender, mother smoking during pregnancy, length of breastfeeding, introduction to solid foods before 4 months.

^cAdjusted for child's gender, frequency of sport per week, frequency of active playing with a parent per week, frequency of TV watching, frequency of PC use, bedtime, frequency child is taken to the playground.

^dAdjusted for child's gender, fruit portion per day, eating breakfast every day, maternal BMI and sweet drinks consumption.

^eAdjusted for child's gender and all risk factors.
