Development of a Novel Mobile Health App to Empower Young People With Type 1 Diabetes to Exercise Safely: Co-Design Approach.

Background: Blood glucose management around exercise is challenging for youth with type 1 diabetes (T1D). Previous research has indicated interventions including decision-support aids to better support youth to effectively contextualize blood glucose results and take appropriate action to optimize glucose levels during and after exercise. Mobile health (mHealth) apps help deliver health behavior interventions to youth with T1D, given the use of technology for glucose monitoring, insulin dosing, and carbohydrate counting.

Developing type 1 diabetes resources: a qualitative study to identify resources needed to upskill and support community sport coaches.

Introduction: Community sport coaches in Western Australia lack an understanding, the confidence, and knowledge in supporting young people with Type 1 diabetes (T1D). This study aims to identify what T1D educational resources are required to upskill coaches in Western Australia.

Methods: Semi-structured online interviews were conducted with i) young people living with T1D, ii) parents of young people living with T1D and iii) community sport coaches.

A Novel Mobile Health App to Educate and Empower Young People With Type 1 Diabetes to Exercise Safely: Prospective Single-Arm Mixed Methods Pilot Study.

Background: Empowering young people with type 1 diabetes (T1D) to manage their blood glucose levels during exercise is a complex challenge faced by health care professionals due to the unpredictable nature of exercise and its effect on blood glucose levels. Mobile health (mHealth) apps would be useful as a decision-support aid to effectively contextualize a blood glucose result and take appropriate action to optimize glucose levels during and after exercise. A novel mHealth app acT1ve was recently developed, based on expert consensus exercise guidelines, to provide real-time support for young people with T1D during exercise.

Antidiuretic hormone and the activation of glucose production during high intensity aerobic exercise.

Objective: This study aimed to investigate the role that antidiuretic hormone (ADH) may play in the activation of glucose production during high intensity aerobic exercise.

Materials/methods: This study was part of larger study based on a repeated measures cross-over study design and involved ten adult participants who exercised in the morning at 80 % Opeak for up to 40 min or until exhaustion. During and after exercise, the participants were subjected to a morning euglycaemic/euinsulinaemic clamp while [6,6-H]glucose was infused and blood sampled to measure the endogenous rate of glucose appearance (Ra) and ADH levels.

The Challenges of Being Physically Active: A Qualitative Study of Young People With Type 1 Diabetes and Their Parents.

Background: Benefits of physical activity are well recognized for youth with type 1 diabetes mellitus (T1DM), but being active is challenging. In this study, we aimed to investigate the challenges experienced by adolescents, their parents and young adults with T1DM when they are physically active.

Methods: Six focus groups involving adolescents (13 to 18 years old, n=14) and young adults (19 to 25 years old, n=7) and 4 focus groups with parents (n=14) of the adolescents (13 to 18 years) were established.

Effect of Exercise Intensity on Exogenous Glucose Requirements to Maintain Stable Glycemia At High Insulin Levels in Type 1 Diabetes.

Context: Under basal insulin levels, there is an inverted U relationship between exercise intensity and exogenous glucose requirements to maintain stable blood glucose levels in type 1 diabetes (T1D), with no glucose required for intense exercise (80% V̇O2 peak), implying that high-intensity exercise is not conducive to hypoglycemia.

Objective: This work aimed to test the hypothesis that a similar inverted U relationship exists under hyperinsulinemic conditions, with high-intensity aerobic exercise not being conducive to hypoglycemia.

Methods: Nine young adults with T1D (mean ± SD age, 22.

Effect of Exercise Intensity on Glucose Requirements to Maintain Euglycemia During Exercise in Type 1 Diabetes.

Context: No recommendations exist to inform the carbohydrate amount required to prevent hypoglycemia associated with exercise of different intensities in individuals with type 1 diabetes (T1D).

Objective: The relationship between exercise intensity and carbohydrate requirements to maintain stable euglycemia in individuals with T1D remains to be determined. It was predicted that an "inverted-U" relationship exists between exercise intensity and the amount of glucose required to prevent hypoglycemia during exercise at basal insulinemia.

High incidence of obesity co-morbidities in young children: a cross-sectional study.

Aim: The prevalence of overweight and obesity in children is a public health problem because of future morbidity. However, the prevalence of medical complications in overweight and obese primary school children in Australia is not well documented. As part of the larger, prospective cohort Growth and Development Study, this report aimed to identify the medical complications of obesity in a population-based community sample of primary school-aged children.
