Changes in knowledge, attitudes, and habits in children (A), parents (B), and teachers (C), over the 18-month study period.
Mean values correspond to the weighted total score (WTS). The WTS assumes differential weights to knowledge, attitudes, and habits (70, 20, 10, respectively).
*During this period of time, the initial control group received an 8-month intervention.
†Statistical significance of changes obtained between baseline and 6-month measurements.
‡Statistical significance of changes obtained between 6- and 18-month measurements.
