When you create value labels in EpiData, you are also restricting the values that a field can hold. So value labels never apply to a continuous variable like systolic blood pressure. Value labels are exclusively for coded values.

It seems from the sample.epx file that any data type can have labels. The snippet I included was from the sample file and was for numeric values. So, it seems you could have a field for systolic blood pressure and a label for 160 that says "a bit too high". You can't do this in R (except by using attr() but that has limitations).
