Abstract
Background and aimsTo determine the prevalence of impaired awareness of hypoglycemia (IHA) and self-identification of symptoms in patients with type 1 diabetes (T1D). MethodsA cross-sectional study was conducted on 242 patients with T1D at the Diabetes Treatment Center, Prince Sultan Military Medical City (PSMMC), Riyadh, Saudi Arabia from May 2021 to September 2021. In addition to the demographic data, patients' HbA1c level was also collected. Awareness and symptoms of hypoglycemia were assessed using two validated questionnaire-based methods, namely the Gold and Edinburgh methods. ResultsThe prevalence of IAH among patients with T1D was 62.8% and the presence of IAH was significantly associated with the duration of T1D (p = 0.019). Compared to males, females had significantly higher (p < 0.05) levels of warmth, pounding heart, and inability to concentrate. Compared to unmarried, married patients had significantly higher levels of (p < 0.05) drowsiness, dizziness, and blurred vision. Similarly, compared to school educated, college-educated showed a higher hunger level (p < 0.05). Patients with HbA1c ≥ 7% possess a significantly higher level of drowsiness, dizziness, and hunger. Dizziness, warmth, difficulty speaking, pounding heart, and blurred vision were significantly higher among patients with diabetes duration ≥10 yrs. Nausea was significantly higher among smokers than non-smokers (p < 0.05). ConclusionThe prevalence of IAH is high among patients with T1D in Saudi Arabia. Focused and evidence-based interventions are essential to minimize the hypoglycemia risk among patients with T1D.
