Abstract
This study investigated correlates of eating disorder (ED) psychopathology among adults with type 1 diabetes (T1D). A total of 282 males (n = 112) and females (n = 170) with T1D (18–79 years) participated. Overall, psychological aspects (i.e. illness perceptions, coping strategies, insulin beliefs, anxiety, and depression) were associated with ED psychopathology. Associations were generally stronger among females than males. In a regression model, age, BMI, personal control, and anxiety explained 51% of the variance in ED psychopathology among females, whereas BMI, personal control, and anxiety explained 47% of the variance among males. Greater clinical awareness of health psychological aspects may contribute to reduce the risk of developing ED.
Highlights
Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by lack of insulin production in the pancreas, leading to elevated blood glucose levels and a lifelong need to administer insulin to regulate blood glucose levels and prevent increased risk of morbidity and mortality (Gagnum et al, 2015, 2017; International Diabetes Federation, 2006)
As reported in a previous study (Wisting et al, 2018), 13.3% of the males and 24.8% of the females scored above the cutoff for disturbed eating on the Diabetes Eating Problem Survey-Revised (DEPS-R), and mean DEPS-R total score was significantly associated with HbA1c among females (0.27, p < 0.01), but not among males
This study investigated the impact of age, BMI, and psychological aspects on Eating Disorders (ED) psychopathology among adults with T1D
Summary
Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by lack of insulin production in the pancreas, leading to elevated blood glucose levels and a lifelong need to administer insulin to regulate blood glucose levels and prevent increased risk of morbidity and mortality (Gagnum et al, 2015, 2017; International Diabetes Federation, 2006). T1D is associated with a higher risk for developing eating disorders (ED), with a 2–3 fold increased prevalence of ED in females with T1D compared to females without T1D (Mannucci et al, 2005; Nielsen, 2002; Young et al, 2012). Intentional insulin omission for weight control is reported in up to 30% of females with T1D (Goebel-Fabbri et al, 2008). T1D and comorbid ED are associated with increased risk of diabetes complications and increased rates of mortality (Nielsen et al, 2002), underscoring the importance of knowledge about potential predictors for the development of ED in this patient group. Reported correlates of ED psychopathology in adults with T1D include negative affect (Merwin et al, 2015; Moskovich et al, 2019), poorer executive
