Eating disorders and oral health: a scoping review on the role of dietitians

Oral health knowledge, attitudes and practices of dietitians in Australia: A national survey

AIM

Dietitians are a well-placed profession to be providing pre-emptive oral health promotion. Despite recommendations that oral health promotion should be routinely part of dietetic practice, there is limited data informing the current practices of clinical dietitians in this area across Australia. Hence, the aim of this study was to investigate the knowledge and practices of Australian dietitians and oral health promotion.

METHODS

A cross-sectional survey was undertaken involving registered clinical dietitians in Australia using purposive and snowballing sampling (social media/dietetic organisations/public databases). Data were analysed using descriptive and inferential statistics.

RESULTS

A total of 149 dietitians participated in the national survey. Overall, dietitians were knowledgeable about oral health risk factors and preventative measures across general health domains. Majority of dietitians agreed that oral health can affect nutrition interventions (95.5%) and dietitians should be discussing oral health (88.0%). However, nearly half were not confident in providing counselling or education and felt that undergraduate training for oral health promotion was inadequate (78.2%). A small proportion (6.0%) of dietitians were already providing oral health promotion regularly. Key barriers included a lack of clear guidelines for practice, limited training opportunities and indistinct referral pathways.

CONCLUSION

Dietitians have acknowledged that oral health promotion should be incorporated into their practice. However, they are challenged by a lack of resources and training to support this in clinical practice. SO WHAT?: Capacity building dietitians to promote oral health allows opportunity for improvement in the oral health, nutritional status and quality of life of priority population groups.

Oral health and individuals with a lived experience of an eating disorder: a qualitative study

BACKGROUND

Limited evidence exists describing the impact to oral health when living with an eating disorder and the availability of information or access to oral health services. This study investigated the perceptions of individuals with a lived experience of an eating disorder specifically to understand their needs and recommendations for improving access to early intervention and oral health promotion.

METHODS

Using purposive sampling a total of 12 semi-structured interviews were conducted with participants across Australia who had a lived experience of an eating disorder. A hybrid inductive and deductive approach to thematic analysis was used to construct salient themes and subthemes.

RESULTS

Most participants had experienced some oral health manifestation as part of their eating disorder hence, many felt quite knowledgeable on the topic. Following their eating disorder many participants felt confident in engaging with dental services, although, barriers including embarrassment, shame, and cost compromised access at times. Participants felt strongly that greater emphasis on oral health promotion during an eating disorder was important and this may be achieved by increasing the availability of resources and using trusted non-dental health professionals like dietitians.

CONCLUSIONS

The need for oral health promotion while experiencing an eating disorder was evident, however, dentists can often be a costly option. Non-dental health professionals like dietitians working with clients with an eating disorder may be an acceptable alternative for closing this gap.

Dietitians' Experiences of Providing Oral Health Promotion to Clients with an Eating Disorder: A Qualitative Study

(1) Background: Eating disorders (EDs) can seriously impact oral health, leading to irreversible dental damage. Dietitians play a key role in the care of people with an ED and are well-placed to promote oral health. However, there is currently little understanding of how dietitians perceive their role in this space. This study aimed to explore the perceptions and role of dietitians in providing oral health promotion to their clients in an ED clinical setting. (2) Methods: This descriptive qualitative study used semi-structured interviews to explore the perceptions of 14 registered dietitians practicing across seven states in Australia. Participants were recruited using a combination of purposive and snowball sampling. A hybrid thematic analysis approach was undertaken to identify and describe the key themes generated from the data. (3) Results: Generally, dietitians were insightful and knowledgeable of the oral health issues that clients with an ED may be experiencing. However, dietitians' practices across education, screening, and referrals were inconsistent. Challenges such as inadequate training, unknown referral pathways, and clear guidelines were cited as significant barriers to practice. (4) Conclusions: The results reinforce the need for education and the development of targeted strategies that address challenges to oral health promotion in dietetic practice.

Quantitative data collection approaches in subject-reported oral health research: a scoping review

Background

This scoping review reports on studies that collect survey data using quantitative research to measure self-reported oral health status outcome measures. The objective of this review is to categorize measures used to evaluate self-reported oral health status and oral health quality of life used in surveys of general populations.

Methods

The review is guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) with the search on four online bibliographic databases. The criteria include (1) peer-reviewed articles, (2) papers published between 2011 and 2021, (3) only studies using quantitative methods, and (4) containing outcome measures of self-assessed oral health status, and/or oral health-related quality of life. All survey data collection methods are assessed and papers whose methods employ newer technological approaches are also identified.

Results

Of the 2981 unduplicated papers, 239 meet the eligibility criteria. Half of the papers use impact scores such as the OHIP-14; 10% use functional measures, such as the GOHAI, and 26% use two or more measures while 8% use rating scales of oral health status. The review identifies four data collection methods: in-person, mail-in, Internet-based, and telephone surveys. Most (86%) employ in-person surveys, and 39% are conducted in Asia-Pacific and Middle East countries with 8% in North America. Sixty-six percent of the studies recruit participants directly from clinics and schools, where the surveys were carried out. The top three sampling methods are convenience sampling (52%), simple random sampling (12%), and stratified sampling (12%). Among the four data collection methods, in-person surveys have the highest response rate (91%), while the lowest response rate occurs in Internet-based surveys (37%). Telephone surveys are used to cover a wider population compared to other data collection methods. There are two noteworthy approaches: 1) sample selection where researchers employ different platforms to access subjects, and 2) mode of interaction with subjects, with the use of computers to collect self-reported data.

Conclusion

The study provides an assessment of oral health outcome measures, including subject-reported oral health status and notes newly emerging computer technological approaches recently used in surveys conducted on general populations. These newer applications, though rarely used, hold promise for both researchers and the various populations that use or need oral health care.
