Keeping the faith: Receptiveness, capacity and acceptability of Islamic religious settings to deliver childhood obesity prevention interventionBackground: Childhood obesity rates among South Asian populations in the UK are significantly high. 10% of childhood population in the UK are of South Asian origin, majority of them follow Islamic faith and attend Islamic religious settings (IRS) daily after school. IRS may be appropriate channels for obesity prevention initiatives; however there is limited evidence for this approach. Methods: Using a qualitative research methodology, we conducted 20 indepth interviews with parents of 5-11 years old children attending IRS, 20 indepth interviews with Islamic leaders, and 3 focus group discussions with 26 managers and workers of IRS in Bradford and Birmingham in the UK. The guides for interviews and focus groups, tailored to each group of participants, were developed from a literature review and prior learning from the results of other work packages in the same study. Interviews and focus group discussions were audio-recorded, transcribed, and analysed thematically. Results: IRS are receptive to delivering a childhood obesity prevention intervention. Most of them have the capacity and the delivery would be acceptable to parents of children attending these settings. All participants viewed Prophet Muhammad’s physical fitness, food and his attitude towards physical activity and maintaining healthy lifestyle as the best role model to follow. Managers and workers in IRS showed willingness to conduct physical activity sessions for South Asian boys and girls and emphasised the need to have female instructors and role models to encourage South Asian girls. Practical barriers for the intervention delivery were poor funding systems and time constraints for managers and workers. Conclusion: IRS can deliver childhood obesity prevention interventions. Interventions should be co-designed, culturally/religiously sensitive and combine the scientific guidelines on healthy living with Islamic narrative on importance of physical activity and healthy diet consumption and should involve local place-based groups for delivery.
