TROMSO_RH_MENOP

Name: RH_MENOP

Short description: Menopausal status

Type: Integer

Description and values:

• 0=Pre-menopausal
• 1=Post-menopausal
• 2=Peri-menopausal
• 3=Post surgical menopausal
• 4=Unknown post menopausal status
• 9=missing

Local variable explanation:

MENOPAUSE_AGE_T4 : If you no longer menstruate, how old were you when you stopped menstruating?

MENS_DATE_U70_T4 : If you still menstruate or are pregnant, what date did your last menstruation period begin (pu70)?

SAS code:

if MENOPAUSE_AGE_T4>0 then RH_MENOP=1;

else if MENS_DATE_U70_T4 >0 then RH_MENOP=0;

else RH_MENOP=9;

MORGAM_RH_MENOP

The RH_MENOP variable is defined using the MORGAM variables MENOP and REMENOP, and the CHANCES variables SEX and CONTACT_AGE.

MENOP
"Are you still having monthly periods?"
1 = yes, as usual
2 = yes, but irregularly
3 = no
8 = not relevant (for men and known pregnant women)
9 = insufficient data

REMENOP
"If you have stopped having monthly periods was it because of"
1 = hysterectomy, alone
2 = hysterectomy, oophorectomy unknown
3 = bilateral oophorectomy with or without hysterectomy
4 = menopause
8 = irrelevant (MENOP on Form 20 = 1, 2 or 8)
9 = insufficient data

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

* Asterisk in the above table indicates that the data on menopausal status is missing or incomplete, and therefore the following rule is used:

"(IL)" in the table indicates an illogical combination of MENOP and REMENOP. Records with such coding are extremely rare in the MORGAM data.

If SEX=1 (MALE), 9 is coded for RH_MENOP.

ESTHER_RH_MENOP

if F24RGBL = 1 then RH_MENOP = 0;
if F24RGBL = 0 and RH_Hyster = 0 and F26OVAR in (0,1) then RH_MENOP = 1;
if RH_Hyster = 1 then RH_MENOP = 3;
if F26OVAR = 3 then RH_MENOP = 3;
if contact_age <= 55 then RH_MENOP = 2;
if RH_MENOP = . and sex = 2 then RH_MENOP = 4;
if sex = 1 then RH_MENOP = 9;
if sex = 1 then RH_MENOP = 9;

Source of F24RGBL and F26OVAR is participant's questionnaire at baseline.
Variables RH_Hyster and contact_age are CHANCES variables.

EPIC_RH_MENOP

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

EPIC var definition(s):
MENOP: EPIC elderly variable showing menopausal status (1=yes, 0=no)

Coding rule:
Variable RH_MENOP shows menopausal status and is identical to MENOP.

Coding rule in STATA:
-gen RH_MENOP =  MENOP
