5-2-1-0 Activity and Nutrition Challenge for Elementary Students: New, Evidence-Based, Promising.

Obesity prevention in youth is a health priority, and teaching healthy habits toward this end is one of a school nurse's many responsibilities. A school nurse developed and implemented a school-wide, 2-week-long Activity and Nutrition Challenge (ANC) using the evidence-based 5-2-1-0 initiative to prevent and fight childhood obesity. Despite minimal promotion, nearly half of the students at two elementary schools participated and earned points by following the guidelines in the ANC.
