I'm trying to perform a cross-national analysis of DHS data that includes a variable assessing whether or not a baby received postnatal care within a certain time period, using M70/M71. In looking through the recodes, M70 (baby postnatal check within 2 mos) seems to have a large number of "Not applicable" responses. I can't see where these responses are coming from based on the skip patterns in the questionnaires (they do not seem to be babies born only at home vs. in a facility as identified in M15, for example). This is the case in a number of the surveys I'm looking at, but Bangladesh 2011 and Benin 2011-12 are two examples.

Can anyone provide any clarification on where these "Not applicable"s are coming from? Thanks in advance.

Following is a response from Senior DHS Stata Specialist, Tom Pullum:


These questions are only asked about the most recent birth. If, say, you open BDKR61FL.dta in Stata and enter "tab m70 bidx, m", you will see that all of the NA cases are for births with bidx>1.

While I see that Tom Pullum answered your specific question, as a broader solution you may wish to check the "Universe" tab for variables of interest on the IPUMS-DHS website (at idhsdata.org). If you go to "select data" on the website, choose "children" as the unit of analysis, and then search for the variable m70, you can click on the variable name to get detailed documentation on the variable, including a "Universe" tab that specifies, for each sample, who is included in the coverage for this variable. In general, M70 is limited to last born children, but some samples include additional limitations.
For example, here's one of the more complicated universes for this variable:
Pakistan 2006: Last-born children under age 5 born to ever-married women age 15-49 who either a) delivered this child away from a medical facility, or b) if delivery took place in a medical facility, received a health check after leaving the facility.

The IPUMS-DHS staff has empirically checked all reported universes for all samples in all variables included in the database, which now covers 117 samples and 28 countries. Checking the universes for variables and samples of interest on IPUMS-DHS's website can save you time and help you avoid inadvertent errors.

Dear Sir/Madam,
I am comparing postnatal care for newborns in 2008 and 2014 in Ghana. I do not see "postnatal care for newborns' in the 2008 GHDS report and so I calculated it using inputs from some post on this forum but will like to know if the syntax is correct.

*###########conditions for postnatal care####
* age in months
gen age = v008-b3
lab var age "Age in months"
ta age
sort caseid bidx
* keep if under 24 months and living with mother
keep if age<25 & b9==0
codebook b9
* ... and keep the last born of those. If caseid is the same as the prior case, then not the last born.
drop if _n > 0 & caseid == caseid[_n-1]

gen posnababy=m71
replace posnababy=1001 if m71<=202 & m71!=.
replace posnababy=1000 if m71>202 & m71<=316
replace posnababy=1000 if m71==998 |m71==999
ta posnababy
Thank you.

Following is a response from Senior DHS Stata Specialist, Tom Pullum:

Usually, v008-b3 will be the same as hw1, and you can use hw1. However, I see that in this file there are 15 cases in which v008-b3=hw1+1. Why, I don't know (I will look into that), so go ahead and use v008-b3.

Your method for selecting the youngest child living with the mother is not quite correct. After "keep if age<25 & b9==0" you could enter these lines, which will sort each woman's children who are living with her by age, and then select the youngest one:

sort age
egen sequence=seq(),by(caseid)
tab sequence
drop if sequence==1
drop sequence
I don't understand what you are trying to do with your recode of m71. Why are you recoding it into 1000 and 1001?

Hello Bridgette,
Thanks for the response.
1000 and 1001 represent 0 and 1 respectively.

I made some changes in the syntax but it still does not give the expected result (6.3%) and the number of observations keep changing.
Your further assistance will be appreciated.

Below is the code.
gen age = v008-b3
lab var age "Age in months"
ta age
sort age
egen sequence=seq(),by(caseid)
tab sequence
drop if sequence==1
drop sequence

drop if m71==.
gen postnatal=m71
replace postnatal=1 if m71==100|m71==101| m71==201 |m71==202
recode postnatal 102=1
replace postnatal=0 if m71>202
ta postnatal

Following is a response from DHS Senior Research Associate, Lindsay Mallick:

Please see program (attached and below) for calculating PNC. PNC is calculated for mothers and babies for the most recent births in the two years preceding the survey. Be sure to exclude women who could not identify the provider of the check. Also, note the way we collect information and calculate PNC has become more precise in DHS-7 surveys. See program attached and below.

*Generate weight
iw=v005/1000000

*DHS-7 and later surveys will have the b19 variable, age in months 
*To create age in months in older surveys, run the following lines
               capture confirm variable b19
               if _rc { // b19 does not exist, so create equivalent for old calculation method
                              gen b19 = v008 - b3
                              label variable b19 "Age of child in months or months since birth"
               }
