Background
Pretravel consultations are a major opportunity to educate travellers about health risks at their destination and how to mitigate them [One group particularly at risk of health problems during travel are voluntary service overseas (VSO) workers, who spend long periods of time working in remote or challenging environments in low-and middle-income countries. United Kingdom’s VSO was founded in 1958 and has been implemented in over 70 developing countries [The aims of self-care for oral health activity are to achieve oral health-related goals through increased oral care knowledge and changes in attitude and behaviour. Interventions to improve oral health-related behaviours need to be designed based on a psychological model or theory [In this study, we developed an evidence-based self-care for oral health e-learning program for Japanese overseas workers using the IMB model, and we assessed the feasibility and acceptability of a self-care for oral health e-learning intervention for long-term Japanese overseas workers.
