    Abstract:
    Given the current childhood obesity epidemic, it is especially important to find effective ways to promote healthful foods to children. School public address (PA) systems represent an inexpensive and a replicable way of reaching children with health messages. To test the effectiveness of this channel, messages were created to promote 2 dried bean (legume) dishes that had been added to the school lunch menu. Six elementary schools were pair matched, and 1 school from each pair was randomly chosen to play the messages. The impact of the intervention on choice of the 2 new entrees was assessed. Results indicate that for all schools combined, choice was not significantly affected. However, compared to their matched control schools, choice was significantly higher in the school that received the highest dose of the intervention and was significantly lower in the school that received the lowest dose. Choice was not changed in the school that received an intermediate dose. These results suggest that PA systems show promise as an effective and appropriate communications channel but only in schools that are able to play messages frequently.
