Time trends in physical activity from 1982 to 2012 in Finland

Area of Science:

• Public Health
• Epidemiology
• Physical Activity Research

Background:

• Physical activity trends are crucial for understanding population health.
• Changes in leisure time, commuting, and occupational physical activity (LTPA, CPA, OPA) can impact public health outcomes.
• Understanding trends across demographic groups is essential for targeted interventions.

Purpose of the Study:

• To analyze population trends in LTPA, CPA, OPA, and total physical activity in Finland from 1982 to 2012.
• To investigate how these physical activity trends vary by educational level and body mass index (BMI) categories.
• To identify changes in physical activity patterns over a 30-year period.

Main Methods:

• Utilized data from independent, cross-sectional population surveys conducted every five years between 1982 and 2012.
• Included a large sample of 21,903 men and 24,311 women who completed health examinations and questionnaires.
• Calculated total physical activity by combining LTPA, CPA, and OPA data, analyzing trends by education and BMI.

Main Results:

• High LTPA significantly increased in both men (21% to 33%) and women (12% to 27%) between 1982 and 2012.
• High CPA and OPA showed a marked decrease in both genders over the study period.
• Total physical activity remained relatively stable, but disparities in LTPA and OPA widened across educational and BMI groups.

Conclusions:

• Significant shifts in physical activity patterns occurred in Finland between 1982 and 2012, with a notable rise in leisure-time activity.
• Declines in commuting and occupational physical activity were observed, contributing to stable overall activity levels.
• Increasing disparities in physical activity by education and BMI highlight the need for targeted public health strategies.
