When data were analyzed for the adult subgroup who completed
the food frequency questionnaire at both time points
(n46), there were no differences between the average intakes
at baseline and those at year 1 in any of the macro- or
micronutrients assessed (data not shown), that is, the variability
within the nutrient studied was greater than the
change observed between the baseline and year 1 visits. Given
the stability of the dietary intake data and for simplicity, only
the baseline data are presented here.
