Abstract:
This study examined effects of an order form intervention on choice of healthy ingredients among college students ordering submarine sandwiches (subs). Over eight weekly sub-nights, college students submitted 9765 orders. The order form format was manipulated in one condition making the healthier selections more salient. Main outcome measures were selection of ingredients. Multi-level logistic regression, chi square, and analysis of variance were used to examine the effect of experimental conditions on selection of ingredients. The health-salient form increased selection of healthier and decreased selection of unhealthy ingredients. The manipulation increased fiber, decreased sodium, but did not impact calorie/fat levels of the subs served.
