Summary
Active youth with type 1 diabetes (T1D) who fear hypoglycemia (FOH) engage in more behaviors to avoid exercise-related hypoglycemia. This fear is linked to higher physical activity levels and poorer blood sugar control, indicating a need for better education.
Area of Science:
- Pediatric Endocrinology
- Sports Medicine
- Diabetes Management
Background:
- Fear of hypoglycemia (FOH) is a significant concern for individuals with type 1 diabetes (T1D).
- Youth with T1D often participate in physical activity (PA), which can impact glycemic control.
- Understanding the relationship between FOH, avoidance behaviors, and exercise is crucial for optimizing diabetes management in active adolescents.
Purpose of the Study:
- To explore the association between FOH, specific behaviors aimed at avoiding hypoglycemia, and exercise in active youth with T1D.
- To investigate how parental FOH relates to youth's physical activity levels.
- To determine if FOH is linked to exercise-induced hypoglycemia avoidance strategies and overall glycemic control (HbA1c).
Main Methods:
- A cohort of 30 active youth with T1D (mean age 15.0 ± 2.4 years) on insulin pump therapy participated.
- Participants completed the 'Type 1 Diabetes Report of Exercise Practices Survey (T1D-REPS)' and hypoglycemia fear surveys (HFS).
- Clinical data, including HbA1c and insulin pump downloads, were collected; 28 participants also completed a 3-day PA recall survey.
Main Results:
- Higher child and parent FOH scores, particularly behavior-related scores, were associated with higher PA levels.
- Increased FOH behavior scores in children correlated with greater avoidance of exercise-associated hypoglycemia.
- Higher child FOH worry and total scores were linked to elevated HbA1c levels, indicating poorer glycemic control.
Conclusions:
- Active youth with T1D exhibit increased hypoglycemia avoidance behaviors as FOH rises, driven by behavioral aspects of fear rather than worry.
- These avoidance behaviors are associated with higher physical activity levels and worse glycemic control.
- There is a clear need for enhanced educational strategies to help youth with T1D manage exercise-induced hypoglycemia effectively while improving overall glycemic control.

676
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

4.1K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

01:16Insulin: Dosing Regimen and Adverse Effects
545
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
