Hello,

I am estimating pregnancy outcomes among reproductive women in India using IR file from the latest IDHS 2019-21. The Earlier IDHS 2015-16 provides vcal_7 variable (IR file) to estimate the pregnancy outcome variable. Recently, IDHS 2019-21 round dropped vcal_7 variable and provides vcal_1 and vcal_2 variables to estimate pregnancy outcome variable (B= Live Birth & M= Miscarriages in vcal_1 and A= Abortion & S= Stillbirth in vcal_2). Therefore, I estimated the pregnancy outcome variable using IDHS 2019-21 data (IR file), which didn't match with the Table 6.15 pregnancy outcome from the report (https://dhsprogram.com/pubs/pdf/FR375/FR375.pdf). My estimation reported 178,876 sample, while Table 6.15 reported 255,549 sample. Unfortunately, my estimation indicated that 76,673 sample were missing. Please find the attached file of my estimation of pregnancy outcomes (1= Live Birth, 2= Abortion, 3= Miscarriages, 4= Stillbirth) as well as Table 6.15.

Your timely response will be very helpful.

Kind regards,
Monirujjaman Biswas

Following is a response from DHS Research & Data Analysis Director, Tom Pullum:

I was not able to view the first jpeg you attached. I got an error message saying that the file was corrupted. Perhaps a different format would work. However, I think I know what you did and you do not need to re-post. I could open the second attachment, but there is no need to send attachments for the tables in reports--I can easily find them.

A major problem with your approach is that the M, A, and S you have found in vcal_1 and vcal_2 do not refer to miscarriages, abortions, and stillbirths. I will try to post the code to construct Table 6.15 in the next day or so. Hopefully I will be able to match it.

Dear Tom Pullum,

Hope you are doing well. I was not able to match the pregnancy outcomes (Table 6.15) using 2019-21 Indian Demographic Health Survey. Based on your last reply, I didn't get any updates regarding the code to estimate pregnancy outcomes among reproductive women in India. Your timely response will be very helpful.

Kind regards,
Monirujjaman Biswas

Following is a response from DHS Research & Data Analysis Director, Tom Pullum:

In the IR file, vcal_1 gives terminations (T) but does not break them down by miscarriage, abortion, stillbirth (MAS). The file includes two variables that are relevant to the last pregnancy. One is v231, which gives the cmc of the last pregnancy termination that was not a live birth and s234, a survey-specific variable, which gives the MAS breakdown. The cmc of the last birth (B) is b3_01. These variables (v231, s234, and b3_01) should be sufficient to calculate table 6.15, which refers only to the most recent pregnancy in the past five years and gives the full BMAS breakdown. However, when I try to construct table 6.15, I do not get a match. The percentages are close but the N is very different. I am checking with other DHS staff but have not heard back from them. We will post a full response, with Stata code, as soon as we can.

Dear Sir,

Thank you so much for sharing this information and giving your time to make it possible. Even I am so more worried about this specific indicator. Except for the adverse pregnancy outcomes as a part of my PhD objective, I have completed all other objectives using National Family Health Survey (NFHS)  4 and 5 datasets. Also, I estimated and matched the pregnancy outcome with the NFHS report (Table 6.15) using NFHS 4 data. But, the latest NFHS 5 has made a lot of modifications, including the estimation of pregnancy outcomes. Although I had constructed the indicator but failed to match the pregnancy outcome (both percentage and numbers) using NFHS-5 data. I will be grateful for your assistance

Kind Regards,

I am checking with others here at DHS regarding the construction of table 6.15. I hope we will be able to post more soon.

Dear Sir,

Hope you are doing well. Would you please guide me on how to construct pregnancy outcomes (table 6.15) using 2019-21 NFHS data?

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

Sorry for the delay in answering your initial question about the construction of Table 6.15 in the NFHS-5 report. This turned out to be a difficult question. Both Trevor Croft and I have looked into it.

Here is the title of the table: "Table 6.15. Pregnancy outcome Percent distribution of last pregnancies among women age 15-49 during the 5 years preceding the survey by pregnancy outcome, according to background characteristics, India, 2019-21". I have highlighted "last pregnancies".

The first issue is that this table was actually calculated with ALL pregnancies in the past 5 years, using a calendar variable called vcal_7. The second issue is that vcal_7 was not included in the IR file (IAIR7BFL.dta is the current version). DHS will add vcal_7 to the next version of the IR file, but as it stands, but it is not possible to reconstruct table 6.15 with the IR file. In most surveys, vcal_6 would be the calendar variable that specifies miscarriages, abortions, and stillbirths, but for this survey it was vcal_7 and vcal_7 was dropped.

It is possible to construct a table that does correspond with the table title, using b3_01, v231, and s234 in the IR file. However, there is no such table in the report, and this is not a matter of matching a table in the report. There are some ambiguities in such a program, such as what do to when the most recent pregnancy was twins and one was born alive and the other was a stillbirth, so I will not attach it.

To summarize, the title and the numbers in Table 6.15 are not consistent with each other. It is not possible to replicate the table with the current version of the IR file.

Dear Sir,

Thank you for the information, and sorry for replying delay. I really appreciate both of you, Sir, for giving your efforts as well as crucial time to solving this issue. Recently, DHS modified the IR data file (IAIR7DFL.dta as the current version) and added vcal_7, SCAL and v019a variables. I have constructed Table 6.15 in the NFHS-5 report using the vcal_7 variable, although it was not possible to matche the numbers and percentages in Table 6.15 with this current version of the IR file. Below, I have attached the table of pregnancy outcomes. As you mentioned that table 6.15 is not possible to reconstruct with the IR file, would you please guide me on whether my estimation of pregnancy outcomes "last pregnancies" is correct or not, or I will have to modify it further?

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

Thanks very much for YOUR work on Table 6.15 of the NFHS-5 final report! Thanks to you, the omission of vcal_7 from the IR file was discovered, and a new version (7D) was issued. Glad you were able to get close to matching Table 6.15 with the new file (revising the table title to refer to ALL pregnancy terminations in the past 5 years). It does not surprise me that you did not get an exact match. We all have difficulty matching the NFHS-5 tables exactly, and it would not be worth trying to get an exact match.

Your distribution for the most recent pregnancy, consistent with the actual table title, matches almost exactly with what I get, and I think you can be satisfied with it.

Thanks again.

Thank you so much, Sir, for your Kindness, Help, and for paying attention to this issue. Without your efforts, it won't be possible, so thank you again.
