Hello,
I am trying to recreate Table 11.1 (Page 149) in the Rwanda 20142015 DHS report. I am specifically looking at the heightforage variable and I am trying to figure out which variable was used in the Rwanda 20142015 data set to obtain these results. I was using the variable hw5 (in the KR: Children's recode data file) which measures the height/age standard deviation (from the reference mean) but I noticed that when I did a quick tabulation of this variable that the total number of children was only 3,524 while in the report the total number of children is 3,813. I did recode the variables=9998 to missing so that these would be eliminated from my calculations. Where is this 3,813 number of children coming from? Or am I using the wrong variable?
I am trying to calculate the percentage of children stunted (<2 s.d.) and severely stunted (<3 s.d.) based on this data, which the report suggests is 37.9% of children and 13.5% of children respectively.
Thank you,
Rachel

Hello,
@Rachel, did you find the solution to the unmatching numbers? I am asking because I think I am in the same situation now. For you, I think you could have used the PR recode file instead of the KR file.
In my case, I would like to get the total percentage of stunted children as mentioned in the Rwanda DHS 2015.
I used the variable HC70 which is in the PR recode file (I read somewhere on the forum that DHS uses the household member recode file for calculation of child anthropometry).
The total number of children in the report is indeed 3813. But when I check the total number of children for the variable HC70 in the PR file, it is 3825.
Thus, the percentage I am getting for stunted children is 37.5% which is slightly different from the one reported of 37.9%. If I calculate stunting per the two categories, severely stunted and moderately stunted I get the same percentage (13.5%) for severely stunted as the one in the report. When I add up the % of severe (13.5%) and moderate stunting (24.1%) I obtained, I get a prevalence of 37.6%. So the mismatch (of around 0.3 to 0.4%) is coming from the calculation of moderately stunted children.
Please members clarify for me where I am getting it wrong.
Thanks,
Hope

In case, someone else reads this thread, I am posting this message to correct a mistake above:
To estimate the number of stunted children correctly as in the DHS report,
1. You have to use the weight variable (HV005/1000000)
2. You have to select de facto children using HV103.
In the message above, I had obtained the same percentage of stunted children (37.9%) as in Table 11.1 of Rwanda DHS 201415, but the denominator I had was 3825 instead of 3813 (reported).
After taking into account de facto children, I came up with the same percentage and also the same denominator as in the DHS report.
