title: Lower A1c among adolescents with lower perceived A1c goal: a cross-sectional survey.
abstract: BACKGROUND
  The International Society for Pediatric and Adolescent Diabetes (ISPAD) and the American Diabetes Association (ADA) have established a hemoglobin A1c (A1c) target of less than 7.5% for adolescents with type 1 diabetes (T1D). However, many adolescents are unaware of their A1c target, and little data exist on how knowledge of this A1c target affects the actual A1c they achieve. We sought to evaluate the relationship between awareness of the A1c target and the actual A1c achieved in adolescents with T1D.
  
  
  METHODS
  In a cohort of 240 adolescents with T1D age 13-19 years, we measured A1c and administered a questionnaire to assess their knowledge of the ISPAD guideline for A1c target.
  
  
  RESULTS
  Of the total cohort, 42 subjects (18%) had an A1c below target and 198 subjects (82%) had an A1c above target. Almost all subjects (98%) reported that they were told their A1c target by a healthcare provider, and most of those (88%) claimed to know their A1c target, but few (8%) were correct. More subjects with actual A1c below 7.5% thought their A1c goal was lower than the ISPAD target, compared to subjects with A1c above target (75% vs. 59%, p = 0.07), although this did not achieve statistical significance.
  
  
  CONCLUSIONS
  In this cohort of adolescents with T1D, there was a trend toward a lower achieved A1c in those with a lower perceived A1c goal. Further studies should focus on identification of factors influencing an adolescent's ability to achieve a lower A1c.
