title: Frequency of diabetes, impaired fasting glucose, and glucose intolerance in high-risk groups identified by a FINDRISC survey in Puebla City, Mexico.
abstract: BACKGROUND
  As a first step in the prevention of diabetes, the International Diabetes Federation recommends identification of persons at risk using the Finnish type 2 Diabetes Risk Assessment (FINDRISC) survey. The frequency of diabetes mellitus, impaired fasting glucose, and glucose intolerance in high-risk groups identified by FINDRISC is unknown in our country. The aim of this study was to determine the frequency of diabetes mellitus, impaired fasting glucose, and glucose intolerance in higher-risk groups using a FINDRISC survey in an urban population.
  
  
  METHODS
  We used a television program to invite interested adults to fill out a survey at a television station. An oral glucose tolerance test was performed in all persons with a FINDRISC score ≥ 15 points (high-risk and very high-risk groups). Patients were classified as normal (fasting glucose < 100 mg/dL and 2-hour glucose < 140 mg/dL), or having impaired fasting glucose (fasting glucose 100-125 mg/dL and 2-hour glucose < 140 mg/dL), glucose intolerance (fasting glucose < 126 mg/dL and 2-hour glucose 140-199 mg/dL), and diabetes mellitus (fasting glucose ≥ 126 mg/dL or 2-hour glucose ≥ 200 mg/dL). We describe the frequency of each diagnostic category in this selected population according to gender and age.
  
  
  RESULTS
  A total of 186 patients had a score ≥ 15. The frequencies of diabetes mellitus, impaired fasting glucose, glucose intolerance, and normal glucose levels were 28.6%, 25.9%, 29.2%, and 16.2%, respectively. We found a higher frequency of diabetes mellitus and impaired fasting glucose in men than in women (33% versus 27% and 40% versus 21%, respectively) and more glucose intolerance in women than in men (34% versus 16%, P < 0.05). Patients with diabetes mellitus (52.55 ± 9.2 years) were older than those with impaired fasting glucose (46.19 ± 8.89 years), glucose intolerance (46.15 ± 10.9 years), and normal levels (41.9 ± 10.45 years, P < 0.05). We found a higher frequency of diabetes mellitus in those aged over 50 years than in younger subjects (46.15% versus 15.88%, respectively).
  
  
  CONCLUSIONS
  The FINDRISC survey is a very useful tool for identifying individuals at high risk of developing diabetes and prediabetic states, especially in those older than 50 years.
