['To analyse, in a population-based study, the association between parental fear of hypoglycaemia and (i) the prevalence of hypoglycaemia and diabetes treatment factors in children with Type 1 diabetes and (ii) emotional distress in mothers and fathers.', 'Mothers (n = 103) and fathers (n = 97) of 115 children with Type 1 diabetes (1-15 years old) participated in the study. In addition to demographic and disease-specific data, the participants completed the Hypoglycaemia Fear Survey-Parent version (HFS-P) (worry and behaviour subscales) and the Hopkins Symptom Checklist-25 items (HSCL-25) to measure emotional distress.', "A higher HFS-P worry score was associated with higher glycated haemoglobin (HbA(1c)), a higher frequency (>or= 7) of what parents experienced as problematic hypoglycaemic events during the past year and co-morbid disease in the child. A higher HFS-P behaviour score was associated with children receiving insulin injections compared with using an insulin pump and a higher frequency (>or= 7 per day) of blood glucose measurements. The mothers had higher scores than the fathers in both the worry and behaviour subscales. The mothers' and the fathers' HFS-P worry scores correlated significantly with their HSCL-25 scores."] Is fear of hypoglycaemia in mothers and fathers of children with Type 1 diabetes associated with poor glycaemic control and parental emotional distress : a population-based study?
