Study Objective:
Is there a difference in self-reported physical activity between the Norse and Sami population, and could the activity levels have been differently reported in the two ethnic groups?
Design:
Cross-sectional, population-based study. In addition, we performed interviews to validate the questions used in the survey to measure physical activity.
Setting:
Finnmark County, Norway.
Participants:
866 men and 860 women of Sami origin, and 4105 men and 3948 women of Norse origin. Attendance rate 77.7%. In addition, we interviewed ten Sami-speaking and seven Norwegian-speaking persons about physical activity.
Main Results:
Among men, the two ethnic groups differed in leisure time physical activity (chi" = 11.462, p = 0.009). Sami women were less active than Norse women in leisure time (chi" = 21.568, p < 0.001). Both Sami men and women were significantly more active during work than Norse persons (chi" = 93.819, p < 0.001 for men and chi" = 59.323, p < 0.001 for women).
Conclusions:
Sami men and women were more physically active at work and had a higher total physical activity score than Norse men and women. The variables used to measure different aspect of physical activity seem to be valid in a diverse ethnic population.
