Bring Blood Glucose Down! An intervention to reduce fear of hypoglycemia in caregivers of adolescents with type 1 diabetes: Study design and participant characteristics

Fear of hypoglycemia (FOH) is anxiety or extreme worry about having a low blood glucose and its consequences. FOH is common in individuals with type 1 diabetes (T1D) of all ages, as well as their caregivers, and can lead to inappropriate T1D self-management and suboptimal health outcomes. Despite its prevalence and serious health consequences, there has been very little attention focused on developing interventions to reduce FOH and its associated maladaptive T1D management behaviors. The primary aim of the present study, Bring BG Down!, was to implement a pilot intervention targeting FOH in mothers of adolescents with T1D. Exploratory aims included determining if the intervention had an impact on the adolescent's FOH, glycemia, as well as other generalized anxiety symptoms or symptoms of obsessive-compulsive disorder in both the mother and adolescent. Caregiver participants and their adolescents with T1D were randomized to either the Bring BG Down! group or the Control group. Individuals in the Bring BG Down! group participated in intervention sessions for 6 months via telehealth and they completed questionnaires, whereas those in the Control group only completed questionnaires. Followup occurred at 7-months and 10-months. The purpose of this paper is to describe the Bring BG Down! study design and rationale, and participant characteristics at the start of the study.
