Summary
Disordered eating behaviours (DEBs) affect one-third of adults with type 1 diabetes (T1D) in Spain, linked to poorer health and lifestyle factors. Early screening and multidisciplinary care are crucial for managing T1D and DEBs.
Area of Science:
- Endocrinology
- Psychiatry
- Public Health
Background:
- Type 1 diabetes mellitus (T1D) management can increase the risk of disordered eating behaviours (DEBs).
- Understanding the prevalence and associated factors of DEBs in T1D is crucial for effective intervention.
- Previous research indicates a link between diabetes management and eating disorders, necessitating further investigation in diverse populations.
Purpose of the Study:
- To determine the prevalence of DEBs among adults with T1D in Spain.
- To identify sociodemographic, clinical, and lifestyle factors associated with DEBs in this population.
- To inform targeted screening and management strategies for DEBs in T1D.
Main Methods:
- A nationwide cross-sectional study (D1ANAS project) included 451 adults (≥16 years) with T1D in Spain.
- Disordered eating behaviours were assessed using the Diabetes Eating Problems Survey-Revised (DEPS-R).
- Multivariate linear regression analyzed associations between DEPS-R scores and various influencing factors.
Main Results:
- 31.7% of participants screened positive for DEBs, with higher rates in women.
- Higher DEPS-R scores were associated with female sex, elevated HbA1c, increased BMI, poorer perceived health, lower diet quality, and poor sleep perception.
- Insulin restriction behaviours were reported by 36.6% of participants, without significant sex differences.
Conclusions:
- DEBs are prevalent in approximately one-third of Spanish adults with T1D.
- Factors such as poor metabolic control, higher BMI, and adverse lifestyle/psychosocial elements are linked to DEBs.
- The findings underscore the necessity for diabetes-specific screening and integrated, multidisciplinary care for individuals with T1D and DEBs.

01:19Type I Diabetes III: Clinical Manifestations
Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...
01:26Type II Diabetes I: Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
01:23Binge Eating Disorders
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...
01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
01:28Anorexia Nervosa
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

01:26Type I Diabetes II: Pathophysiology
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
