grade intervention including school food service modifications, enhanced physical education (PE), and classroom health curricula. Twenty-eight additional schools received these components plus family education. Main Outcome Measures.\p=m-\Atthe school level, the two primary end points were changes in the fat content of food service lunch offerings and the amount of moderate-to-vigorous physical activity in the PE programs.

Individual level secondary end points included psychosocial factors, recall measures of eating and physical activity patterns, and other physiologic measures. Results.\p=m-\Inintervention school lunches, the percentage of energy intake from fat fell significantly more (from 38.7% to 31.9%) than in control lunches (from 38.9% to 36.2%)(P
