Why Are Some Population Interventions for Diet and Obesity More Equitable and Effective Than Others? The Role of Individual Agency

Summary

Summary Points • Public health interventions can be described according to where they lie on two continuums: the population and high-risk approaches anchor one continuum, while the other continuum captures the personal resources (or “agency”) individuals have to use to benefit from interventions. • Population interventions that require individuals to use a high level of agency to benefit tend to be favoured by governments around the world. • Population interventions that require individuals to use a low level of agency to benefit are likely to be most effective and most equitable. More effort is required to develop, evaluate, and implement population interventions that require low levels of agency for individuals to benefit.

Key Points

• 1High-agency interventions may not be effective for all population groups
• 2Low-agency interventions can achieve better health outcomes without requiring extensive individual effort
• 3Socioeconomic disparities affect the ability to engage with high-agency initiatives
• 4Current public health strategies often overlook the benefits of low-agency methods
• 5Acceptance of low-agency interventions may improve public health without compromising autonomy
