Why the study?

Are physical fitness and leisure physical activity associated with coronary risk factors in a general population?

This study investigates the relationships between physical fitness, leisure physical activity, and coronary risk factors in a population sample.
Cross-sectional study design with a random sample of 297 men and 312 women from the Tromsø municipality in Norway (1986-1987).
Fitness assessed via bicycle ergometry and physical activity reported through a questionnaire.
Multiple regression analysis used to explore associations between fitness, leisure activity, and coronary risk factors.
Physical fitness and leisure activity were positively related (p<0.05).
Fitness showed negative associations with age (p<0.05) and smoking (p<0.05), with positive links to body mass index (p<0.01).
In men, HDL cholesterol and systolic blood pressure were significant predictors of fitness (p<0.01), while smoking negatively impacted leisure activity in women (p<0.01) and a negative relation between leisure activity and total cholesterol was found in men (p<0.01).

Are physical fitness and leisure physical activity associated with coronary risk factors in a general population?

Population

609 subjects (297 men born 1925-1966 and 312 women born 1930-1966), randomly selected from a population survey in Tromsø, Norway.

Outcome

Associations between physical fitness (tested by bicycle ergometry), leisure physical activity (questionnaire), and coronary risk factorssurrogate

Coronary risk factors are more closely linked to objectively measured physical fitness than to self-reported leisure physical activity.

May support fitness assessment over self-reported activity for coronary risk profiling; hypothesis-generating and requires longitudinal confirmation.
