Thanks ever so much Pedro, Richard and Marcel. I was away and just returned. I am sure your suggestions and insights will amply address my my question. Regards, Ali

Dear Ali,
It seems to be a simple task. First, as far as I know the BMI is calculated as weight/(heigh*heigh). However this values should be in Kg and m. If you have the data in pounds and feet, then youl should transform them before. To make it easier, create a variable in the qes file with this information.
qes file
v1 heigh in feet ##.# v2 heigh in m #.## v3 weight in pound ###.## v4 weight in Kg ###.# v5 bmi ##.##
chk file
v1 after entry let v2 = round(v1*0,4536) end end
v2 noenter end
v3 after entry let v4=round(v3/3,28) end end
v4 noenter end
v5 before entry let v5=v4/(v2*v2) goto v6 end end
I hope this works fine for you because didnt test it! ;)
Succes, Pedro Emmanuel Brasil

Thanks. I just recently started using Epidata, and I need some help on creating
a
Check string for automatically calculating BMI using Weight and Height
(in
pounds and feet/inches). Thanks, again.

I useful little trick I picked up for us crazy Americans who insist on using inches and pounds: Calculate pounds/(height in inches)^2. Multiple the result by 703.0814 (or however precise you want the result) and you have BMI.

Have a look at the many available documentations on the web. A similar thing (calculating age from date of birth) is included on page 6 of a very useful intro (A brief overview of EpiData software) to be found on http://www.tbrieder.org/ (follow icon to "Revised EpiData course") marcel
