Matching a_natchild and w_newborn datasets
100%
Description
Dear Mr or Mrs
I hope you are doing well, I am trying to check birthweight as an initial outcome. I know that xwavedat has the birthweight of only BHPS participants. So I merged each w_newborn with w_child to include birthweight and breastfeeding measures to the child data (I merge the datasets I need within a wave, for instance, a_indall, a_indresp, a_hhresp etc) as w_hidp and w_pno changes across waves.
However, the birthweight for the first wave is in a_natchild, yet I was not able to use the variables or merge it with any other datasets
Below, I attached a short do.file which shows what I did.
Would it be possible to have a look and help ?
Please do let me know if my question or the do.file is not clear
Thanks a lot
Best Regards
Omer

Hello Omer,
I suggest reviewing the Pregnancy and Early Childhood (PEACH) file (SN9075). The study gathered data from all children reported in the main survey. The information is at the child-level, using each child’s unique person identifier number to make them identifiable across all waves. The data include, among others, birth weight.
Please note that the PEACH file excludes children that in wave 1 were older than 6 years. If you wish to add this subsample you may append those in wave 1 a_natchild with birthweight to PEACH to have the full sample. Please be aware that the pidp in a_natchild is the parent's, not the child's.
If you want to follow this approach, note that code “-32 N/A - only in child file" it's for children that have been reported in the child file, but we couldn't find them neither in the “newborn” file nor in the “natchild” files. Consequently, specific information (such as birth weight) for these cases is unavailable.
For more details regarding the PEACH file, please refer to https://www.understandingsociety.ac.uk/blog/2023/07/03/%E2%80%98peach%E2%80%99-data-%E2%80%93-a-single-source-on-child-development-information
I hope this information is helpful.
Best wishes,
