INS and diabetes mellitus: The DISABKIDS instruments discriminated between groups based on metabolic control (HbA1c) and age in that increasing HbA1c and age were associated with lower HRQOL, while no significant differences were found with respect to gender, duration of diabetes or insulin pump vs. multi-injections treatment, although there was a tendency that pump-users rated the impact of disease less and social equality higher than those on multi-injections.
