  1. a. Alternative cut-point for categorisation of 'eating fruit at least once daily' also including students eating fruit 5–6 days a week (every day, more than once + once a day, every day + 5–6 days a week)
  2. b. Significant gender difference within each age group (chisquare test, p< 0.02)
  3. c. Significant trend in prevalence by age (Cochrane-Armitage tests for trend, p < 0.02)
