Abstract:
The rising tide of obesity erodes the health of youths and many times results in adult obesity. The purpose of this investigation was to examine the effectiveness of an eight-session health promotion/transtheoretical model Internet/video-delivered intervention to increase physical activity and reduce dietary fat among low-income, culturally diverse, seventh-grade students. Those who completed more than half the sessions increased exercise, t (103) = -1.99, p = .05, and decreased the percentage of dietary fat, t (87) = 2.73, p = .008. Responses to the intervention by stage of change, race, and income are examined.
