FV, fruit and vegetable; IQR, interquartile range.

Values are mean or % (se), or median (IQR) and range.

Weighted means and percentages are reported for all student-level variables. Snack intake measured at wave 2; all others measured at wave 1 (baseline).

^*A score of 0–1 measured the diversity of land use in schools’ ZIP code tabulation area with 0 representing the most homogeneous land use and 1 representing the most diverse land use.

^†Percent of the population with income of less than 185 % of the Federal Poverty Level.
