MORGAM_PA_VIGOROUS

This variable is not harmonized in MORGAM, but some cohorts can convert it from their local data.

Glostrup (DEN-GLO)

Describe here the local data item(s) and how the CHANCES variable PA_VIGOROUS was derived from it.

Greifswald (GER-GRE)

Describe here the local data item(s) and how the CHANCES variable PA_VIGOROUS was derived from it.

Northern Sweden (SWE-NSW)

PRIME Belfast (UNK-BEL)

PA_VIGOROUS was coded as PA_SPORT if the participant replied to the categorical PRIME Belfast variable “HARDPHYS: Which of the following four activity classes best describes your travel of activity outside work? (Consider getting to and from work, sport activity and other physical effort during your leisure time, like gardening or dancing)” with either “3=vigorous physical activity at least 20mins once or twice a week (vigorous activity causes shortness of breath, a rapid heart rate, and sweating)” or “4= vigorous physical activity for at least 20mins three of more times per week.” Similarly, PA_VIGOROUS_YESNO was coded 1 if a PRIME Belfast participant replied 3 or 4 to the question above.

ESTHER_PA_VIGOROUS

pa_vigorous = L47BTNUS;
if pa_vigorous = . then pa_vigorous = 9999;

Source of L47BTNUS is participant's questionnaire at baseline

EPIC_PA_VIGOROUS

EPIC variable M_VIGPA was used for the production of PA_VIGOROUS.

EPIC var definition(s):
M_VIGPA = Epic elderly Greece variable showing MET hours spent for vigorous activities

Coding rule:
Variable PA_VIGOROUS is produced from the following formula: M_VIGPA/9.

Coding rule in STATA: 
-gen PA_VIGOROUS=M_VIGPA/9

Comment: _M_VIGPA was created based on the non-extreme values of the cases. It was created using a mean MET value of 9 corresponding to vigorous activities.
