A feasibility study of a WhatsApp-delivered transtheoretical model-based intervention to promote healthy eating knowledge and habits for firefighters in Hong Kong: A cluster randomized controlled trial
Abstract Background Firefighters’ health is affected by a high prevalence of obesity and cardiovascular diseases, which are common risk factors for sudden cardiac death. The aim of this study was to investigate the feasibility of enhancing healthy eating habits and knowledge in firefighters through an education programme.Method This will be a cluster randomized control trial study. The participants will be assigned randomly into either control (health promotion pamphlet) or intervention (health promotion pamphlet and education materials through WhatsApp) groups. Changes in healthy eating habits and knowledge will be assessed by a self-administrative questionnaire and anthropometric measurements at three different time points.Discussion More education is required in order to improve firefighters’ eating habits and knowledge.
