简要总结
The investigators hypothesize that the new United States Department of Agriculture (USDA) regulations for lunches served as part of the National School Lunch Program will decrease the percentage of enrolled students purchasing lunch, increase the percentage of children taking fruit and vegetables, decrease the percentage of fruit and vegetable servings being thrown away, and increase the total number of fruit and vegetable servings eaten.
The investigators also hypothesize that when the regulations are in force, simple behavioral interventions can counteract the potentially negative impact on lunch sales and consumption. In other words, implementing the regulations and behavioral interventions together, the percentage of enrolled students taking a school lunch will increase at least back to baseline levels, the percentage of children taking fruits and vegetables will increase, the percentage of fruit and vegetable servings wasted will decrease, and the total number of fruit and vegetable servings eaten will increase.
详细描述
This study was conducted in 43 schools in the New York City (NYC) School district in the spring of 2012. The new regulations for school lunches were scheduled to roll out nationally in the fall of the same year, so this study was designed to provide an indication of the impact the new regulations would have.
In addition to the regulations, the investigators also tested additional behavioral interventions, in conjunction with the regulations, to determine how the behavioral interventions might offset, or magnify, the impacts of the regulations.
