1) G = grain, M = meat, V = vegetable, F = fruit, and D = dairy product group: 1 = food group (s) present, 0 = food group (s) absent
For example GMVFD = 11100 indicate that grain, meat and vegetable were provided and fruit and dairy product groups were not provided.
2) by chi-square test
3) Others included '10110', '10101', '10111', 11010', and '11000'
1) by paired t-test

1) by chi-square test
1) 1 point for never, 2 points for rarely, 3 points for neutral, 4 points for usually, or 5 points for always
2) by Wilcoxon's signed-ranks test
1) 1 point for really decreasing, 2 points for decreasing, 3 points for no change, 4 points for increasing, and 5 points for really increasing
1) 1 point for strongly disagree, 2 points for disagree, 3 points for neutral, 4 points for agree, and 5 points for strongly agree
2) by paired t-test
1) 1 point for strongly disagree, 2 points for disagree, 3 points for neutral, 4 points for agree, and 5 points for strongly agree
