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

Dear Hope,
I am doing a trend analysis of Nepal DHS data on the nutrition status of under 5 years in different waves from 2001-2016. I merged PR and KR file as I am interested to see both children and maternal-related variables. I am using SPSS.
Problem 1
While working for the data analysis, I could replicate the exact figure from the report for stunting only for the year 2016 data. And could not find a similar figure as in report for other waves (2001, 2011, 2016) with similar consideration. for example, I get 2485 instead of 2475 in 2011 and 5258 instead of 5262 in 2006. I have tried many times and I am taking into consideration:-
a) sample weight variable (HV005/1000000)
b) selected de facto children using HV103
Syntax used : Stunting
recode hc70 (lo thru -201 = 1) (-200 thru 9990 = 0 ) (else=sysmis) into stunting.
variable labels stunting "Stunting".
value labels stunting 0 "Not stunted" 1 "Stunted".
formats stunting (f1.0).
compute wgt = hv005/1000000.
weight by wgt.
compute filter_$=(hc70 < 9990 & hv103=1).
variable labels filter_$ 'hc70 < 9990 & hv103=1 (FILTER)'.
value labels filter_$ 0 'Not Selected' 1 'Selected'.
formats filter_$ (f1.0).
filter by filter_$.
execute.
frequencies stunting.
Problem 2 :
a)Should I merge the HW file to PR or KR file? Or merge HW file with merged datasets of KR and PR file?
I would be grateful if you can share the ideas for solving these issues. I am struggling with this difference in figures.
Thank you.
