Objectives: Type 2 diabetes mellitus (T2DM) and periodontal disease are two highly prevalent, directly and independently associated long-term conditions that disproportionately impact Indigenous Māori in New Zealand (NZ). Although poorly understood, a number of social and biological mechanisms connect these conditions. This qualitative study explored experiences of T2DM and oral and dental (hereafter oral/dental) health; access to oral/dental health care; whether participants' experiences supported or challenged existing evidence; and sought suggestions for improving oral/dental health in a high-deprivation rural area of Northland, NZ.
Methods: Participants (n = 33) meeting the study criteria: self-identified Māori ethnicity, aged ≥ 18-years with glycated haemoglobin (HBA1c) >65 mmol/L were recruited via the local primary care clinic in September-December 2015; two left the study prior to data collection. During face-to-face semi-structured interviews, participants (n = 31) were asked How does diabetes affect your teeth? and When did you last access dental care? Kaupapa Māori (KM) theory and methodology provided an important decolonizing lens to critically analyse the fundamental causes of Indigenous health inequities.
Results: Independent analysis of qualitative data by three KM researchers identified four themes: access barriers to quality care; pathways to edentulism; the 'cost' of edentulism; and, unmet need. Results contributed towards informing Mana Tū-an evidence-based KM programme for diabetes in primary care-to be introduced in this and other communities from 2018.
Conclusions: Oral health is integral to diabetes management, and vice versa. Subsidized specialist referrals for oral-dental health care for Māori with T2DM could improve glycaemic control and diabetes outcomes and reduce diabetes-related complications among this population.
