ABSTRACT

Objective: To identify the sensitivity and specificity of occasional fast and postprandial glycemias as for a chronic control of the type-2-diabetic patient.
Material and methods. Design: descriptive, cross-sectional in 850 type-2-diabetic adults patients from the outpatient clinic of the Zone General Hospital and Family Medicine 9 in Ciudad Guzmán, Jalisco, Mexico, without insulin therapy, with creatinine values lower than 132.6 mmol/L (1.5 mg/dL), and glycemia over 4.4 mmol/L (80 mg/dL).
Procedure: Blood extraction was carried out to determine fasting glycemia, cholesterol, triglycerides and glycosilated haemoglobin (HbA1c). After that, they were given a breakfast of 320 Kcal, and new blood samples were taken for postprandial glycemia. The statistical programs used were Epi-Info 2000, Epi-Dat.
Results: Age, 59. ± 11.2 years old; antiquity in diabetic diagnosis, 4.8 ± 6.7 years; fasting glycemia average, 9.9 ± 4.4 mmol/L (178.6 ± 79.4 mg/dL); postprandial glycemia, 14 ± 6.1 mmol/L (251.6 ± 109.6 mg/dL); HbA1c, 9.3 ± 3.4 %. An acceptable fasting glycemia presents an adequate chronic control sensitivity of 44.8 %, with a specificity of 82.1 %. On the other hand, a postprandial glycemia presented a sensitivity of 46.5 % and specificity of 77.3 %; both acceptable parameters have a sentivity of 31.4 % and specificity of 83.3 % to identify a good control of HbA1c.
Conclusions: Random parameters present very little sensitivity to the diagnosis of a good chronic control of the patient; however, as screening tests, they show an acceptable specificity for the HbA1c poor values.
