1 FFQ1 and FFQ2, the same FFQ was firstly administered at baseline (FFQ1) and secondly (FFQ2), between 9 to 12 months later. 2 p-value from paired t-tests; 3 r: coefficient correlations after food groups intakes were log-transformed; 4 r adj: correlation coefficient using food groups intakes adjusted for total energy; the correlations coefficients had a p-value < 0.01 when r ≥ 0.20, and a p value < 0.05 when 0.15 ≤ r ≤ 0.19.
