title: Prevalence of high normal FBS and prediabetes among adolescents in Birjand, East of Iran, 2012.
abstract: OBJECTIVE
  To determine the prevalence of impaired fasting glucose in adolescents in Birjand city in eastern Iran.
  
  
  METHODS
  This cross-sectional study was done on 2653 students aged 11-18 years selected through multi-stage stratified and random sampling. Fasting blood glucose (FBS) of these students was measured applying the enzymatic process. The obtained data were analyzed by means of SPSS software (V: 15) and statistical tests T and X2.
  
  
  RESULTS
  The mean age of individual was 14.5 ± 2 years. Mean FBS of the whole population was 89.8 ± 9.8 mg/dl, but it was significantly higher among boys than girls (P < 0.001). Out of the whole subjects (92.4%), 1,328 (95.1%) of the girls and 1,122 (89.3%) of the boys, FBS was less than 100 mg/dl among whom 64.4% had FBS above 86 mg/dl. In 200 subjects (7.5%) of whole population, FBS was 100-125 mg/dl; with that of the boys was 2.3 times than the girls revealing a prediabetes condition: OR = 2.3(CI: 1.7-3.2). Among the students, 3 (0.1%) had an FBS > 126 mg/dl. Mean blood glucose was significant regarding age and sex.
  
  
  CONCLUSIONS
  High prevalence of high FBS (within normal range) among adolescents is warning and requires special attention of health officials. Screening of children and adolescents in order to identify those at risk and plan for intervening is urgent to prevent type-2 diabetes epidemic and following cardiovascular complications in the Society.
