30 (1) Changes in Health- Related Behaviors Between 2001 and 2002 Among Two Child Cohorts of the CABLE Study Lee-Lan Yen, Ling-Yen Pan, Likwang Chen, Szu-Hsien Lee, Chuhsing Hsiao,

31 Major Findings Most of the positive health behaviors showed similar or increased rates over the two years. Decreased rates were only found in wearing a motorcycle helmet and brushing teeth before sleeping. The prevalence rates of performing negative health behaviors and the rates of children who changed to good or bad behaviors over the two years varied depending on the behavioral item, cohort, and area. Using vulgar language, drinking alcohol, and suicidal ideas are three problem behaviors with great potential in increase among children.
