title: Alexithymia is associated with glycaemic control of children with type 1 diabetes.
abstract: OBJECTIVE
  This study examined the respective contributions of the demographics, medical variables and alexithymia characteristics of young diabetics to their glycaemic control. The goal was to replicate the role of the 'difficulty describing feelings' factor of alexithymia in the prediction of poor glycaemic control as has been found in adult diabetic populations.
  
  
  METHODS
  The study included 45 type 1 diabetic children, aged 8-12 years (24 girls and 21 boys). Participants completed a sociodemographic questionnaire and provided medical information on their diabetes. HbA(1c) values (glycated haemoglobin), and the number of severe hypoglycaemic episodes and hospitalizations for hyperglycaemia, were collected for the previous 12 months (3 months for severe hypoglycaemias). Alexithymia characteristics were measured by means of the Alexithymia Questionnaire for children.
  
  
  RESULTS
  Hierarchical regression analyses confirmed that both demographic (marital status and parental education; P<0.05) and medical (duration of diabetes and daily self-monitoring of blood glucose frequency; P<0.01) variables are associated with HbA(1c) levels. More important, one alexithymia factor (difficulty describing feelings) was found to be an additional predictor over and above the other variables (P<0.01), explaining an additional 12% of the total variance in HbA(1c) levels.
  
  
  CONCLUSIONS
  Confirming results already observed in diabetic adults, the present findings show, for the first time, that children who have difficulties in expressing their feelings to others are more at risk of poor glycaemic control. In future, it will be useful to identify the diabetic young people who have such difficulties and to consider interventions designed specifically for them.
