When Low Blood Sugars Cause High Anxiety: Fear of Hypoglycemia Among Parents of Youth With Type 1 Diabetes Mellitus.

Objectives: Hypoglycemia is the most common acute complication of type 1 diabetes (T1D), and the potential short- and long-term sequelae can cause children and parents to develop significant fear of hypoglycemia (FOH). FOH and associated anxiety can be disruptive to activities of daily living and lead to reduced quality of life. We sought to determine the extent of FOH among parents of children with T1D within our clinic and to identify factors associated with greater FOH.

Methods: Two hundred sixty-four parents of youth (2 to 18 years of age; mean ± standard deviation, 12.4±3.5 years) with T1D completed a survey that included demographic and disease-specific questions, the Spielberger State-Trait Anxiety Inventory and the Hypoglycemia Fear Survey---Parent version (HFS-P).

Results: Of the 264 participants, 207 completed the full HFS-P, with a mean score of 67±19 (range, 31 to 119). The most frequent worries related to the child being hypoglycemic while alone or asleep. Higher HFS-P scores were also associated with more frequent and severe hypoglycemic episodes, higher state-trait anxiety scores, use of a continuous glucose monitor and more frequent blood glucose checks. Higher HFS-P scores were also associated with worse parental sleep quality and less parental engagement with treatment plans.

Conclusions: Parents of children with T1D experience FOH, especially during times of high vulnerability. Moreover, FOH could potentially impact clinical care (with parents being reluctant to administer suggested insulin doses) and quality of life (due to parental/child sleep disruption). Further studies are needed to develop and evaluate interventions aimed at reducing FOH in parents of youth with T1D.
