Minimum Meal frequency in BDHS 2014 Wed, 22 February 2017 02:15
 Md. Nurnabi Sheikh Messages: 4Registered: May 2016 Location: Bangladesh Member
I am working IYCF practice on BDHS child datasets for my MPH thesis,and trying to replicate Minimum meal frequency in table 11.6. But I am not able to get same percentages among breastfed children, non-breastfed children and all children age 6-23 months. I am working in stata and my algorithm as follows;

* Last child in the last 2 years living with mother
* age in months
gen age = v008-b3
* drop if too old or not alive
keep if age<24 & b5==1

* keep only those children living with mother ...
keep if b9==0
* ... and keep the last born of those
drop if _n > 0 & caseid == caseid[_n-1]

drop if age<6

*Minimum meal frequency
tab m39, m

*Minimum meal frequency for breastfeed child age 6-8 months, 9-23 months
recode m39 (2/7=1 "2-7"), gen(mm1)
recode m39 (3/7=1 "3-7"), gen(mm2)

*Minimum meal frequency for non-breastfeed child age 6-23 months
recode m39 (4/7=1 "4-7"), gen(mm3)

*Age group
recode age (6/8=1 "6-8")(9/23=2 "9-23"), gen (age_g)

*Breastfeeding status
gen still_feeding=1 if m4==95
replace still_feeding=0 if still_feeding==.

*Minimum meal frequency applying all conditions
gen mmf1=1 if mm1==1 & age_g==1 & still_feeding==1

gen mmf2=1 if mm2==1 & age_g==2 & still_feeding==1

gen mmf3=1 if mm3==1 & still_feeding==0

It would be very much helpful for me if any one help me with stata command.

Regards,
Nurnabi

I think your problem is that when you generate mm1, mm2, and mm3 you are not handling the values outside of the range you specify. For example,

recode m39 (2/7=1 "2-7"), gen(mm1)
should read
recode m39 (2/7=1 "2-7")(else=0), gen(mm1)

Without the else condition, values of m39 that you don't specifically recode are copied over, and thus m39==1 is transferred to mm1 and sets mm1 equal to 1!
Adding the (else=0) will handle these cases.

actually this is the little i have been able to do.

keep if age<24
keep if b9_01==0
tab b9_01
drop if _n > 0 & caseid == caseid[_n-1]
drop if age <6

*Weighting
gen v005_wgt= v005/1000000

*Age group recoding
*NB; clonevar age already deifned @ 26
recode age (6/8=1 "6-8")(9/11=2 "9-11") (12/17=3 "12-17") (18/23=4 "18-23"), gen (age_g)

*recode of m4_1 as number of breastfed and number of nonbreastfed children 6-23months
recode m4_1 (93/94=0 "Number of non-breastfed children 6-23 months") (95=1 "Number of breastfed children 6-23 months"), gen (still_feeding)
replace still_feeding=0 if still_feeding==.

Hello,

I am working for IYCF indicators for Indonesia DHS 2012, how to generated child age in month (using stata)? I could not find this variable yet in the data set. Which file is the best to use, if I want to work on IYCF practice among children aged 0-23 months.

many thanks for your help,

warm regards

Yes, use the KR file for IYCF indicators. for age in months, if b19 exists in the dataset (only datasets since about 2016) use that, if not calculate age in months as v008 - b3. See Calculating the age of children for more information.

Dear All, As a biginner of using DHS Data It is not clear to creat IYCF Index from KR file for me. Thus I need your genuine support how to creat IYCF Index? What are the variables in KR file? I didn't get them.
Thank you for your assistance and guidance.

Dear DHS team,

I would like to confirm my STATA analysis on 8 IYCF core indicators for Indonesian DHS 2012. I found slightly different rates for most indicators. I have followed the discussion in DHS forum and applied the syntaxes.
Here are my findings and the differences with the DHS report:

My analysis DHS report Differences
Indicator Rate (%) Rate (%)
Early Initiation of breastfeeding (0-23mo) 50.02 49.30 0.72
Exclusive Breastfeeding (0-5mo) 42.61 41.50 1.11
Continued Breastfeeding at 1 year (12-15mo) 77.21 77.00 0.21
Introduction to Soft and Semi Solid Food (6-8mo) 90.37 91.00 -0.63
Minimum Dietary Diversity (6-23mo) 58.20 58.20 -
Minimum Meal Frequency (6-23mo) 65.80 66.10 -0.30
Minimum Acceptable Diet (6-23mo) 36.14 37.00 -0.86
Consumption of Iron-rich or iron-fortified foods (6-23mo) 54.21 n/a

I am sending you my syntaxes in attachment, I have checked several times, but could not figure out the reason for such discrepancy.
many thanks for your help

Hi,

here is my commands, however, I got slightly different result compared to DHS report:

Hello,

I am trying to compute the Minimum Meal Frequency from the Indian DHS 2015-16, following the commands given by Nurnabi and Trevor's instructions. My computed percentage (28.66%) is not matching with the reported percentage (35.9%) in the DHS-4 report. However, the sample size (69,690) is matching,
Could you anyone point out my mistake in the commands (below)? Or if possible, share the correct syntax for Minimum Meal Frequency and Minimum Acceptable diet, please.

I am using the following commands:

* Last child in the last 2 years living with mother
* age in months
gen age = v008-b3
* drop if too old or not alive
keep if age<24 & b5==1

* keep only those children living with mother ...
keep if b9==0
* ... and keep the last born of those
drop if _n > 0 & caseid == caseid[_n-1]

drop if age<6

*Minimum meal frequency
tab m39, m

*Minimum meal frequency for breastfeed child age 6-8 months, 9-23 months
recode m39 (2/7=1 "2-7")(else=0), gen(mm1)
recode m39 (3/7=1 "3-7")(else=0), gen(mm2)

*Minimum meal frequency for non-breastfeed child age 6-23 months
recode m39 (4/7=1 "4-7")(else=0), gen(mm3)

*Age group
recode age (6/8=1 "6-8")(9/23=2 "9-23"), gen (age_g)

*Breastfeeding status
gen still_feeding=1 if m4==95
replace still_feeding=0 if still_feeding==.

*Minimum meal frequency applying all conditions
gen mmf1=1 if mm1==1 & age_g==1 & still_feeding==1

gen mmf2=1 if mm2==1 & age_g==2 & still_feeding==1

gen mmf3=1 if mm3==1 & still_feeding==0

*Weight varible
gen wgt=v005/1000000

* Minimum meal frequency for all children (6=23 months)
gen MMF=0
replace MMF=1 if mmf1==1 | mmf2==1 | mmf3==1

tab MMF [iw=wgt]

Thank you,
Sk

Following is a response from DHS Senior Analysis & Research Manager, Shireen Assaf:

The code below will match table 10.10 in the India 2015-16 final report. The problem may be that you had to take into consideration the breastfeeding status of the child using v404. Please see below. The first part of the code is the same as yours to select the youngest child under 2 years living with the mother.

```**** Minimum Meal Frequency Code ****

* Last child in the last 2 years living with mother
* age in months
gen age = v008-b3
* drop if too old or not alive
keep if age<24 & b5==1

* keep only those children living with mother ...
keep if b9==0
* ... and keep the last born of those
drop if _n > 0 & caseid == caseid[_n-1]

drop if age<6

gen wt= v005/1000000

* among breastfed children 6-23 months, minimum meal frequency
* defined as receiving solid or semisolid food at least twice a day for
* infants age 6-8 months and at least 3 times a day for children age 9-23 months
gen minfreq1 = 0
replace minfreq1 =1 if (m39>1 & m39<8 & age>=6 & age<=8) | (m39>2 & m39<8 & age>=9 & age<=23)

*this is for breastfed children
ta minfreq1 if v404==1 [iw=wt]

* For nonbreastfed children age 6-23 months, minimum meal frequency is receiving
* solid or semisolid food or milk feeds at least 4 times a day.
* milk feeds
gen totmilkf = 0
replace totmilkf=totmilkf + v469e if v469e<8
replace totmilkf=totmilkf + v469f if v469f<8
replace totmilkf=totmilkf + v469x if v469x<8

* adding solid or semisolds
gen feedings=totmilkf
replace feedings= feedings + m39 if m39>0 & m39<8

gen minfreq2 =0
replace minfreq2 = 1 if feedings>=4

*this is for non-breastfed children
ta minfreq2 if v404==0 [iw=wt]

****

* Now we combine these variable to get the minimum meal frequency among all children
gen minfreq3=0
replace minfreq3=1 if minfreq1==1 & v404==1
replace minfreq3=1 if minfreq2==1 & v404==0
ta minfreq3  [iw=wt]

*this gives 35.9% and 69,690 children as in the final report
```

Dear Sir/Madam,

Can get a Stata syntax for Minimum Acceptable Diet (MAD) for DHS India. Moreover, the MDD and MMF do not match the Indian DHS 201921 report. Please clarify.

Thanks

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

The Stata syntax for the child nutrition tables is given on our GitHub site: https://github.com/DHSProgram/DHS-Indicators-Stata/tree/mast er/Chap11_NT.

You should be able to find what you need there, but if you want to run the do file(s), be sure to read the setup instructions.

The standard code will often not match the NFHS reports exactly, but you should get close. If you have trouble, let us know but please be specific about which table(s) and numbers you cannot match.
