Binge-eating disorder in adults with newly diagnosed type 2 diabetes - baseline data from the SOUL-D study

Research output: Contribution to journalMeeting abstractpeer-review


Background and aims: The relationship between eating disorders and type 2 diabetes (T2DM) is poorly understood. The published prevalence of binge-eating disorder (BED) ranges from 1.4 to 25.6% among individuals with T2DM. The present study aims to ascertain the prevalence of BED among participants from the South London Diabetes (SOUL-D) Study and its impact on glycaemic control.
Materials and methods: SOUL-D is a community based prospective cohort study examining a range of biological, psychological and social factors in people with newly-diagnosed T2DM. The Eating Disorders Diagnostic Scale (EDDS) was used to screen for BED and the Patient Health Questionnaire (PHQ-9) for depression. BMI and HbA1c were also measured.
Results: From those who completed the EDDS questionnaire (n=1154), 20 reached full BED and 4 subthreshold BED diagnosis, representing 2.1% of the total sample. In comparison to subjects without BED, subjects with BED were significantly younger (mean(SD):50.9(12.6) vs. 55.8(11.5), p=0.032), more likely to be female (83.3% vs. 42.3%, p<0.001), in full-time employment (70.8% vs. 46.0%, p=0.016) and less likely to be married (29.2% vs. 49.8%, p=0.046). They also had higher BMI (37.9kg/m2(9.87) vs. 31.5kg/m2(6.3), p<0.001), poorer glycaemic control (7.53%(1.56) vs. 6.97%(1.45), p=0.047) and more depressive symptoms (9.27(7.34) vs. 4.23(5.22), p<0.001).
Conclusion: There is a significant association between BED and worse metabolic and psychological outcomes in subjects with newly diagnosed T2DM. The finding underscores the relevance of assessing and addressing disordered eating behaviours in patients with T2DM, in order to improve biomedical and psychological outcomes.
