• Menu Board Calorie Literacy Score [ Time Frame: Baseline, Post-Intervention (approximately 10 Weeks), 3-Month Follow Up ]
  Content knowledge of students will be assessed by the total number of correct responses on the survey measures.
• Parental Nutritional Knowledge Score [ Time Frame: Baseline, Post-Intervention (approximately 10 Weeks), 3-Month Follow Up ]
  Nutrition knowledge score will be assessed using a 7-item questionnaire at Baseline, Immediately post intervention, and at 3-months post intervention. Changes in the composite score will be analyzed across each of the test sequences range of 0 - 7, with higher scores representing greater nutrition knowledge.

This study is testing the efficacy of the integrative approach to:

1. teach 5th grade children menu board calorie literacy as measured by our novel recently validated menu board calorie literacy (MBCL) instrument;
2. provide strategies designed to improve food purchasing behaviors; and
3. facilitate the transmission of core lesson messages from children to parents via a procedure that we have termed "Child Mediated Health Communication (CMHC)".

Data show that nearly 25% of children aged four to eight years consumed fast food on a typical day. These trends in fast food consumption are more acute among low-income urban dwellers where higher rates of overweight and childhood obesity are seen. This has led to a focus on providing fast food consumers with point-of-purchase nutrition information, such as the calorie posting mandates, in the hopes that these decision cues will help consumers make better informed dietary decisions. Most children chose their own meals at the point-of-purchase. It is clear that additional strategies are needed to encourage the point-of-purchase use of calorie postings, however available studies provide little insight into best practices or the types of approaches needed.

It is with this in mind that the investigator developed a school-based approach to improve point-of purchase use of calorie postings, by creating a novel intervention that targets menu board calorie literacy as a means of improving food-purchasing behaviors.

Hip Hop Nutrition-Math Curriculum is a novel behaviorally focused multimedia, musical school health rap toolkit that targets what we refer to as menu board calorie literacy. 4th grade common core math standards are integrated into the program in a manner that incorporates evidence-based nutrition education recommendations by the Institute of Medicine and the Centers for Disease Control and Prevention (CDC).

The investigator proposes to test the efficacy of the integrative approach on food purchasing behaviors of children in an adequately powered, controlled trial. The investigator will test the intervention in the after-school setting among economically disadvantaged children and incorporate parental engagement in our outcome evaluations. There is a partnership with New York City's largest after-school program vendor, New York Edge (formerly called Sports and Arts in Schools foundation/SASF), for the implementation of this study.

The goal of a health literacy intervention is to improve health decision-making and/or behavior. For this reason, the investigator will measure both menu board calorie literacy and food choice behavior at a point-of-purchase.

• Behavioral: Hip Hop Nutrition-Math Curriculum
  This program teaches children skills needed to understand restaurant-menu boards, how to make healthy food choices, while reinforcing the common core math concepts they are learning in school. The program consists of: 2 lessons a week, of about 1 hour each lesson, for a total of 20 lessons.
  Other Name: Hip Hop Nutrition math-based education program
• Behavioral: Food Explorers Program
  After-school program Food Explorers will represent "Usual Care". This program comprises food and exploration activities, familiarizing children with diverse foods, nutrition concepts, tasty recipes and physical activity.
  Other Name: Food Explorers Curriculum

• Experimental: Group 2: Hip Hop Nutrition-Math Curriculum
  The intervention group will receive an tailored program for ten weeks, meeting twice a week.
  Intervention: Behavioral: Hip Hop Nutrition-Math Curriculum
• Active Comparator: Group 1: Food Explorers Program
  The control group will receive the usual care for nutrition program provided by the schools, called Food Explorers. The group will also be conducted ten weeks, meeting twice a week.
