Hi (and sorry for cross-posting),
We would like to analyze the change children' weight over time, first by looking at the continuous variable (i.e. weight in kilograms) and then by 3-category variable which is underweight, normal and overweight.
We have 5 measurement over time (i.e. mother was asked to tell the weight ans height her child when he was 5, 18, 30, 48 and 60 months).
I think we can model the weight (continuous variable) with latent growth trajectory. I don't think it is possible with the 3-category variable.
Is there someone who did the same thing ? If yes, can you provide me with SAS/SPSS commands ?
Furthermore, we would like to analyzed what variables (socioeconomic, nutrition, etc) contributed to the change (i.e. being normal to overweight ?). Is it possible to do this ?
Thanks
Manon Girard
