The data are in 282 rows corresponding to each unique combination of the factors 
given in Tables 1 and 2 of the paper.

The first three columns of data contain the response data, and the 4th to the 8th
contain the codes for the covariates.  
The codes for the covariates are 1,2,3..., as applicable, and the order of 
the codes corresponds to the order given in Tables 1 and 2.  For example for 
the first covariate (agegroup)in column 4 the codes are

1= under 19
2= 19-20
3= 21-22
4= 23-24
5= over 24
