I have used the following codes for Nepal DHS 2022 dataset:

gen bmi=v445/100
gen bmic=1 if bmi<18.5
replace bmic=2 if bmi>=18.5 & bmi<25
replace bmic=3 if bmi>=25 & bmi<30
replace bmic=4 if bmi>=30 & bmi<50
label define bmic 1"Underweight" 2"Normal" 3"Overweight" 4"Obese"
label values bmic bmic
gen ht_flag=0
replace ht_flag=1 if v438>9000
gen preg_flag=0
replace preg_flag=1 if v213==1
gen months_since_last_birth=v008-b3_01
gen recent_birth_flag=0
replace recent_birth_flag=1 if months_since_last_birth<=1
tab bmic if ht_flag==0 & preg_flag==0 & recent_birth_flag==0 [iweight=v005/1000000]

The result is following:


bmic | Freq. Percent Cum.
------------+-----------------------------------
Underweight | 936.250508 13.36 13.36
Normal | 4,020.4742 57.37 70.74
Overweight | 1,557.3877 22.22 92.96
Obese | 493.271511 7.04 100.00
------------+-----------------------------------
Total | 7,007.3839 100.00

This does not correspond with the tables 11.21.2 & 11.21.3 in the Nepal DHS survey report 2022. These tables reported nutritional status of 6980 women. Why i can't match their findings? Please help.

Following is a response from DHS staff member, Tom Pullum:

I used the two Stata lines given below, in the IR file, to confirm the n's for these two tables. (For this purpose, I did not need to construct bmic.) The only problem with what you did is that you should have used b19_01 to get the time since the latest birth.

tab v013 if v013>1  & v445<9998 & v213==0 & b19_01>1 [iweight=v005/1000000]

tab v013 if v013==1 & v445<9998 & v213==0 & b19_01>1 [iweight=v005/1000000]
