Impact of after-school nutrition workshops in a public library setting.

OBJECTIVE To determine if after-school nutrition workshops conducted in public libraries were related to lasting changes in food choice. METHODS "Snack Smart" workshops, based on Social Cognitive Theory, were conducted in 8 branch libraries (49 ethnically diverse children, ages 9 to 14) to assess changes in consumption of targeted food items by pretest, posttest, and follow-up food frequency questionnaires. Results were analyzed using the Friedman test for repeated measures and Wilcoxon signed rank test. RESULTS Intake of milk, vegetables, and water significantly increased at 3-week posttest (P < .05), but only water intake showed a significant change from pretest to follow-up 3 months later. CONCLUSIONS AND IMPLICATIONS This low-intensity program did not produce lasting behavior change, as measured by changes in food frequency at 3 months post- intervention. The study supports the need to critically evaluate out-of-school nutrition programs for lasting impact.
