Tharshini,
In your message of June 11 you described how you are merging the
household member data with the anthropometric data. When I reproduce
your approach the data from all household members, adults and
children, appear in the merged file.

You write now that "only information for children is kept" but without
seeing the Stata commands you used it is difficult to understand what
you are doing differently.
The household member file lists the line number of the mother and
father of each child up to 14 years of age in the variables hv112 and
hv114. You can use this line number to create variables with the
parents' age, level of education, etc. As an example, assume you want
to identify the parents' ages. First, sort the data by household ID
and household member line number.
. sort hhid hvidx
Next, generate variables with the mother's and father's age.
. by hhid: gen mage = hv105[hv112]
. by hhid: gen fage = hv105[hv114]
Two FAQs on the Stata website provide information related to your problem.
"How do I create a variable recording whether any members of a group
(or all members of a group) possess some characteristic?"

"How do I create variables summarizing for each individual properties
of the other members of a group?"
