Dear all experts,
I am new here. Can you please let me know how to calculate the minimum acceptable diet and minimum dietary diversity for children aged 6-23 months? Though I have calculated the minimum meal frequency of BDHS 2017-18 and got 79.87%, in the final BDHS report it is 81%. I would also like to request you what error might I did? I used the following syntax:
gen age = V008-B3
keep if age<24 & B5==1
keep if B9==0
drop if _n > 0 & CASEID == CASEID[_n-1]
drop if age<6
gen wt= V005/1000000
gen minfreq1 = 0
replace minfreq1 =1 if (M39>1 & M39<8 & age>=6 & age<=8) | (M39>2 & M39<8 & age>=9 & age<=23)
ta minfreq1 if V404==1 [iw=wt]
gen totmilkf = 0
replace totmilkf=totmilkf + V469E if V469E<8
replace totmilkf=totmilkf + V469E if V469E<8
replace totmilkf=totmilkf + V469E if V469E<8
*
gen feedings=totmilkf
replace feedings= feedings + M39 if M39>0 & M39<8
gen minfreq2 =0
replace minfreq2 = 1 if feedings>=4
*
gen minfreq3=0
replace minfreq3=1 if minfreq1==1 & V404==1
replace minfreq3=1 if minfreq2==1 & V404==0
ta minfreq3 [iw=wt]
*
gen MMF=.
replace MMF=0 if minfreq3==0
replace MMF=1 if minfreq3==1
la de MMF 0 "No" 1 "Yes", replace
la val MMF MMF
la var MMF "Minimum Meal Frequency"
tab MMF [iw=wt]

Hello Tom Pullum,
As per your suggestion, I have used the following syntax. But it does not match the results of table 11.7 of BDHS final report of minimum acceptable diet. Please let me know the problem or how can I fix it.

Following is a response from DHS Lead Nutrition Research Associate, Rukundo Benedict:
For the IYCF indicators, it is important to first select the appropriate age group. You will find the code to use to do this in the on DHS Program GitHub.
Use the !NTmain.do file, lines 98-100 to select the appropriate age group for the IYCF indicators. After you have done this, then you can run the NT_IYCF.do.
