Proportion in multiple regression

Dear list,


Is it legitimate to use proportions as predictor along with other
frequency and dummy variable in a multiple regression?

For example, for the data (tab delimited form uploaded at
http://www.angelfire.com/planet/stata/vl.txt ), i am trying to use
predictors
hh.size., m.adult, proporti, hh.sex, calori1, land.per, d.asset,
per.capi, yr.schoo, hhcrisis
for dependent variable log(food.exp)
where proporti is a proportion.

If i use it, will the interpretation still be the same for the proporti
variable like others?


Thank you for your time.
