To assess differences through grade 8 in diet, physical activity, and related health indicators of students who participated in the Child and Adolescent Trial for Cardiovascular Health (CATCH) school and family intervention from grades 3 through 5. Design : Follow-up of the 4-center, randomized, controlled field trial with 56 intervention and 40 control elementary schools.
We studied 3714 (73%) of the initial CATCH cohort of 5106 students from ethnically diverse backgrounds in California, Louisiana, Minnesota, and Texas at grades 6,7, and 8. Results : Self-reported daily energy intake from fat at baseline was virtually identical in the control (32.7%) and intervention (32.6%) groups.
At grade 5, the intake for controls remained at 32.2%, while the intake for the intervention group declined to 30.3% (P<. 001).
At grade 8, the between-group differential was maintained (31.6% vs 30.6%, P=01).
Intervention students maintained significantly higher self-reported daily vigorous activity than control students (P=001), although the difference declined from 13.6 minutes in grade 5 to 11.2,10.8, and 8.8 minutes in grades 6,7, and 8, respectively.
Significant differences in favor of the intervention students also persisted at grade 8 for dietary knowledge and dietary intentions, but not for social support for physical activity.
No impact on smoking behavior or stages of contemplating smoking was detected at grade 8. (...)
