title: Predictors of hyperglycaemic individuals who do not follow up with physicians after screening in Japan: a cohort study.
abstract: OBJECTIVE
  Although people screened as being hyperglycaemic often fail to follow up with physicians for clinical assessment, epidemiologic findings on the frequency and predictors of not following up (hereafter, "no follow-up") are lacking. The purpose of this study was to examine the no follow-up rate with physicians after screening for diabetes and predictors of no follow-up.
  
  
  METHODS
  We assessed cases of no follow-up with physicians within six months after screening based on medical claims data from employee-based social health insurance programs in Japan, for people aged 20 to 68 years from 2005 to 2010.
  
  
  RESULTS
  Among 3878 screened participants with hyperglycaemia, 2527 (65%) did not follow up with their physicians within six months after screening. Multiple logistic regression analysis revealed that younger age and lower blood glucose level predicted no follow-up among both men and women, while lower body mass index and negative proteinuria also predicted no follow-up among men. Treatment for dyslipidaemia facilitated follow-up among both genders, and treatment for hypertension or depression facilitated follow-up among men.
  
  
  CONCLUSIONS
  Approximately two thirds of individuals screened as having hyperglycaemia did not follow up with their physicians within six months after screening. Predictors of no follow-up were younger age and milder hyperglycaemia. Being on treatment for co-morbidities tended to facilitate follow-up.
