Abstract Introduction:<\b>
Intervention-generated inequalities can emerge when those with existing poor health or health related barriers cannot engage with, or benefit less from, interventions. The present work examined whether current physical activity promotion approaches are at risk of exacerbating health inequalities by examining their reach and engagement in a population with complex barriers. Methods:<\b>
Those sampled (n = 61; 41m, 20f) had: shift-based work patterns, low incomes, and (at a population level) poor health and low physical activity levels. Awareness of physical activity promotion services, their perceived utility, and prior and potential engagement were assessed using questionnaires. Results:<\b>
Participants reported low awareness of physical activity services (M 3.97 (SD 3.47) out of 16 services recognised); males and those aged 55 years and over had significantly lower service awareness than females and younger participants respectively. For those who had accessed existing services (n of uses = 34) perceived utility was high. There was comparable engagement with local and national initiatives. For future engagement, participants were most interested in free or discounted services, and opportunities for physical activity participation as a family. Conclusion:<\b>
Collectively, findings suggest that although existing services are well-received by populations with complex barriers, awareness of and engagement with these services are low. Proportionate targeting of advertising, and support with economic barriers in particular, may be required to ensure low participation groups with a range of barriers benefit from physical activity promotion services.
