Immigration and leisure-time physical inactivity: a population-based study

Area of Science:

• Public Health
• Epidemiology
• Sociology

Background:

• Sedentary leisure-time physical activity is a significant risk factor for cardiovascular disease (CVD).
• Understanding ethnic variations in physical activity is crucial for public health.
• Migration status can influence lifestyle behaviors, including physical activity.

Purpose of the Study:

• To examine the association between migration background and sedentary leisure-time physical activity.
• To identify specific ethnic groups with higher prevalence of sedentary behavior in Malmö, Sweden.

Main Methods:

• Cross-sectional study utilizing data from the 1994 Malmö public health survey.
• A postal questionnaire was completed by 5,600 individuals aged 20-80 years (71% response rate).
• Logistic regression analysis was employed to assess sedentary leisure-time physical activity status, controlling for potential confounders like age, sex, and education.

Main Results:

• Overall prevalence of sedentary leisure-time physical activity was 18.1% for men and 26.7% for women.
• Individuals born in Arabic-speaking countries, other non-European countries, and specific European nations (Yugoslavia, Poland) showed significantly higher odds of sedentary behavior compared to those born in Sweden.
• These associations remained significant after adjusting for age, sex, and education.

Conclusions:

• Significant ethnic disparities exist in leisure-time physical activity levels.
• Sedentary behavior represents a modifiable CVD risk factor that varies by ethnic background.
• Public health interventions targeting specific ethnic subgroups may be effective in reducing sedentary behavior and associated CVD risk.
