In reference to frozen fish consumption, small families and large families present similar behavior in the comparison between the two cohorts: monthly consumption shows a highly significant reduction ( p < 0.001 for small and large families), while we note a significant increase for weekly consumption ( p = 0.001 for small families and p < 0.001 for large families) and for biweekly consumption ( p = 0.027 for small families and p = 0.002 for large families).
