Barriers to physical activity in the Iranian population: findings from the STEPwise surveillance 2021.

BACKGROUND

Physical inactivity is a critical predictor of all-cause mortality and many non-communicable diseases (NCD) including coronary heart disease, diabetes, hypertension, dementia, and several cancers. The main objective of this study was to determine the main barriers to physical activity based on the STEPwise Surveillance in Iran in 2021, to guide policymakers in developing the most effective physical activity increasing strategies.

METHODS

This cross-sectional study was conducted on 27,515 female and male individuals aged over 18 years from the STEPwise Surveillance 2021. The barriers to physical activity according to the modified version of barriers questionnaire and intrapersonal, interpersonal, economic, cultural, and environmental domains based on social-ecological models were determined. Association between barriers domain and physical activity level was assessed.

RESULTS

Lack of time due to job commitments (31.4%) and family (19.3%) and inappropriate physical conditions including illness, pain, injury, disability, and fatigue (30.4%) were the most frequent barriers to physical activity. Interest in sedentary leisure time activities including virtual space, computer games and watching TV were the next frequent barriers to physical activity (10.01%). Intrapersonal domain had the highest frequency (62.9%) and cultural domain had the lowest frequency (2.3%). Intrapersonal and interpersonal barriers reduced the odds of engaging in physical activity (OR: 0.62, P value < 0.001, OR: 0.76, P value < 0.001).

CONCLUSION

Intra- and inter-personal domain barriers might reduce the odds of being active. Developing action plans addressing these factors is suggested to increase physical activity levels.
