Equity in Physical Activity: A Misguided Goal.

Area of Science:

• Public Health
• Exercise Science
• Health Disparities

Background:

• Participation in physical activity varies across demographic groups, leading to the concept of 'inequities'.
• Major health organizations promote 'equity' in physical activity to address these disparities.

Purpose of the Study:

• Critique the goal of achieving equity in physical activity.
• Propose an alternative, objective-driven approach to promoting physical activity.

Main Methods:

• Conceptual analysis of the 'equity' metric in physical activity.
• Examination of assumptions underlying current equity initiatives.
• Development of an alternative public health objective.

Main Results:

• Equity is a misguided goal as it focuses on relative comparisons and ignores absolute activity levels and gap sizes.
• Equity initiatives rely on flawed assumptions regarding health risks, group dynamics, and causality.
• The concept of 'opportunity' is often incorrectly cited as the sole cause of physical activity differences.

Conclusions:

• Health organizations should abandon the goal of equity in physical activity.
• The primary aim should be to increase physical activity in the most sedentary and/or highest health-risk groups.
• Promote physical activity to the highest feasible levels, irrespective of inter-group comparisons, for an objective health outcome.
