ABSTRACT
Ninety-two healthy children provided self-reports of their physical activity. Self-reports were based upon posters depicting children performing typical childhood activities and were validated by measured oxygen uptake during maximal cycle ergometry. Results indicated that when children were classified as sedentary or active by their poster selection, active children had significantly greater oxygen uptake than sedentary children. These results, while preliminary, are the first to indicate that children's self-reports can provide a valid index of maximal oxygen uptake, the 'gold standard' of aerobic fitness.

Our data indicated that self-reports of consumption of salty foods by children and adolescents were associated with 24-hour urinary sodium excretion. Specifically, youths 10 to 18 years of age who selected a poster depicting high-sodium foods excreted significantly more sodium than youths who selected a poster depicting low-sodium foods. Future research is needed to refine simplified self-report measures, to corroborate the validity of the measures, and to extend the studies to other samples, e.g., younger children.
