Abstract
Aims: To determine the impact of frequency of non-severe hypoglycemic events (NSHE) and the perceived burden of NSHE on quality of life (QOL) over time.
Methods: T2D adults (n = 424) were re-contacted two years after initial QOL assessment. Responding subjects (n = 290) reported the frequency and burden of NSHE over time and completed six generic and diabetes-specific QOL measures.
Results: Most subjects (86%) reported ≥ one NSHE over time. Higher frequency of NSHE was significantly associated with decrements in QOL. Greater perceived burden of NSHE was significantly linked to decreases in QOL over time for all six QOL measures. Interaction terms indicated that participants with a higher frequency of NSHE and higher perceived burden reported the greatest decrease in QOL; participants who experienced frequent NSHE but did not perceive these events as burdensome evidenced little worsening in QOL over time.
Conclusions: NSHE have a negative impact on QOL over time in T2D adults. However, it is not just the occurrence of NSHE that affects QOL; it is the individual’s felt burden of these events that is critical. The greatest reductions in QOL are seen among those subjects reporting a higher frequency of NSHE and indicating that such events are burdensome.
