To objectively measure the amount of intensity-specific physical activity by gender and age with respect to body mass index (BMI) during workdays and days off among Finnish employees.
A cross-sectional study.
Primary care occupational healthcare units.
A sample of 9554 Finnish employees (4221 men and 5333 women; age range 18-65 years; BMI range 18.5-40 kg/m(2)) who participated in health assessments related to occupational health promotion.
The amount of moderate-to-vigorous (MVPA) and vigorous (VPA) physical activity (=3 and =6 metabolic equivalents, respectively) was assessed by estimating the minute-to-minute oxygen consumption from the recorded beat-to-beat R-R interval data. The estimation method used heart rate, respiration rate and on/off response information from R-R interval data calibrated by age, gender, height, weight and self-reported physical activity class. The proportion of participants fulfilling the aerobic physical activity recommendation of =150 min/week was calculated on the basis of =10 min bouts, by multiplying the VPA minutes by 2.
Both MVPA and VPA were higher among men and during days off, and decreased with increasing age and BMI (p
