Note. Only n = 9 participants in the control and n = 16 participants in the intervention condition completed the Food Frequency Questionnaire and n = 11 controls and n = 20 intervention participants completed the Godin physical activity index. Due to these limited sample sizes, no F statistics for these measures are reported.
