Hello I am unable to understand definitions for IYCF indicators for nigeria dhs 2008
Among non-breastfed children age 6-23 months, percentage fed:
A) 4+ times or more
B) with 3 IYCF practices
Among all children age 6-23 months, percentage fed:
A) 3+ or 4+ food groups
B) Minimum times or more
C) with all 3 IYCF practices
what is the stata code for developing following indicators was able to generate correct estimates for rest of indicators in table except these need help with this please unable to correct estimates for these indicators

thanks for the reply
yes I am trying to generate Nigeria 2008 Table 11.6 Infant and young child feeding (IYCF) practices have used the definition as of 2018, for all indicators in 2008 correct estimates are being generated except that minimum meal frequency for non-breastfed and among all children are not generating correct estimates although the same definition and coding is giving correct estimates among breastfed children, as result minimum acceptable diet can't be generated for non-breastfed and among all children, following is the code I used
gen age = v008 - b3
* keep youngest child if under 24 months and living with mother **
keep if age < 24 & b9 == 0
* and keep the last born of those.
* if caseid is the same as the prior case, then not the last born
keep if _n == 1 | caseid != caseid[_n-1]

Following is a response from DHS Lead Nutrition Research Associate, Rukundo Benedict:
Dear User,
Thank you for sharing your code. You are on the right track and most of your code is correct. Below I've indicated the changes you need to make to your code to have it match table 11.6.
1. You didn't define mdd4 (or else you didn't include in what you shared). So edit as follows:
*Among breastfed & Non-breastfed
*3+ food groups for breastfed children & 4+ groups nonbreastfed
egen foodsum = rsum(group1 group2 group3 group4 group5 group6 group7 group8)
recode foodsum (1/2 .=0 "No") (3/8=1 "Yes"), gen(mdd3)
recode foodsum (1/3 .=0 "No") (4/8=1 "Yes"), gen(mdd4)
replace mdd3=. if age<6
replace mdd4=. if age<6
label values mdd3 yesno
label var mdd3 "Child with minimum dietary diversity, 3 out of 8 food groups- last-born 6-23 months"
label values mdd4 yesno
label var mdd4 "Child with minimum dietary diversity, 4 out of 8 food groups- last-born 6-23 months"
//Min meal frequency
*Minimum times or more (at least twice a day for breastfed infants 6-8 months and at least three times a day for breastfed children 9-23 months)
gen feedings=milkf
replace feedings= feedings + m39 if m39>0 & m39<8
gen mmf = (m4==95 & inrange(m39,2,7) & inrange(age,6,8)) | (m4==95 & inrange(m39,3,7) & inrange(age,9,23)) | (m4!=95 & inrange(m39,4,7) & inrange(age,6,23))
replace mmf=. if age<6
label values mmf yesno
label var mmf "Child with minimum meal frequency- last-born 6-23 months"
gen milk_milkp= group3 if inrange(age,6,23) & bf_curr==0
gen milkf = 0
replace milkf=milkf + v411 if v411==1
replace milkf=milkf + v411a if v411a==1
replace milkf=milkf + v414p if v414p==1
gen fed_milk= ( milkf>=2 | m4==95|milk_milkp) if inrange(age,6,23)
label values fed_milk yesno
label var fed_milk "Child given breastmilk or milk products"
As a side note, depending on your analyses, you may want to consider using the most recent definitions of the WHO-UNICEF IYCF indicators https://www.who.int/publications/i/item/9789240018389. The pdf includes some also template code for how to calculate/re-calculate these indicators. You can also review the DHS Program git-hub site which has code for how to re-calculate MDD (5 out of 8 food groups).
Thanks,
Rukundo
