TROMSO_RH_N_FTP

Name: RH_N_FTP

Short description: Number of full term pregnancies 

Type: Integer

Description and values: Number of full term pregnancies a woman has had (continuous variable).

• Code "0" if the woman has never been full-term pregnant. 
• Code 9999 for missing/insufficient data

Local variable explanation:

CHILDREN_T4 : How many children have you given birth to?

SAS code:

RH_N_FTP=CHILDREN_T4;

If CHILDREN_T4=0 then RH_N_FTP=0;

else RH_N_FTP=9999;

NSWEDEN_RH_N_FTP

RH_N_FTP=V6;

IF V6=. THEN RH_N_FTP=9999;

V6 is the ma_v6 in the variable list

MORGAM_RH_N_FTP

The RH_N_FTP variable is defined using the MORGAM variables PARITY and PREGNA, and the CHANCES variable SEX.

PARITY
How many live births have you given?
88 = irrelevant (SEX=1. Optionally also if PREGNA = 2)
99 = insufficient data

PREGNA
Have you ever been pregnant?
1 = yes
2 = no
8 = irrelevant (SEX = 1)
9 = insufficient data

If SEX = 2 (FEMALE), the following rule is used:

If SEX = 1 (MALE), 9999 is coded for RH_N_FTP.

EPIC_RH_N_FTP

The EPIC variable N_FTP was used for the production of RH_N_FTP according to the following definition and rule.

EPIC var definition(s): N_FTP: Number of full term pregnancies

Coding rule:
Variable RH_N_FTP shows number of full term pregnancies and is identical to N_FTP.

Coding rule in STATA:
-gen RH_N_FTP = N_FTP

-replace RH_N_FTP=9999 if RH_N_FTP==.
