Developing a dietitian-led oral health promotion program in eating disorder clinical settings: a multi-phase mixed methods study (TASTe study)

Abstract

The prevalence, incidence and magnitude of eating disorders (EDs) are increasing worldwide. In Australia, more than 1 million individuals are estimated to have an ED. Research has established a link between ED and poor oral health. Findings from two systematic reviews identified that individuals with an ED are five times more likely to have tooth erosion and are at an increased risk of developing caries, regardless of ED subtype. Furthermore, studies involving individuals who have experienced a mental health issue, have documented barriers such as shame, stigma or fear of judgement as deterrents from seeking pre-emptive or early intervention oral health care. While the association between ED and adverse oral health outcomes have been well documented, there is a scarcity of in-depth exploratory research investigating the access to oral health promotion and oral health care practices of individuals with an ED. The findings from this body of work provide a critical insight into the individuals lived experience of oral health when impacted by an ED and identifies key requirements including a need for oral health promotion from trusted health professionals and referrals to dental services. Similarly, it also identifies the acceptability of dietitians towards oral health promotion and identified challenges and needs that must be addressed prior to dietitians effectively implementing this into practice. The overall findings suggest that the development of a model of care that addresses the oral health needs of individuals with an ED, including oral health promotion and referral to dental services led by non-dental health professionals, may be a cost-effective and acceptable model by both clients and health professionals to implement in ED clinical settings. However, firstly, further research is needed towards the development of guidelines and training that adequately prepares the professional to provide oral health promotion. Policy should also consider improving access to subsidised dental services.
