Longer diabetes duration was associated with lower intensity of autonomic symptoms and a higher prevalence of impaired awareness of hypoglycaemia, suggesting that subjective symptoms of hypoglycaemia change over time. These observations underline the need for regular patient education about hypoglycaemia symptomatology and clinical screening for impaired awareness of hypoglycaemia.

In this sample of Norwegian adults with type 1 diabetes, women expressed more concerns about hypoglycemia than men. The highest HFS-II-Worry scores occurred in the same items in women and men, but the largest gender differences in mean scores appeared across a variety of other items, some of which were related to social esteem.
