Frequency of self-monitoring and its effect on metabolic control in patients with type 2 diabetes

The aim of the study was to investigate the frequency of self-monitoring of blood glucose in patients with type 2 diabetes and to determine its effect on metabolic control measured as glycosylated hemoglobin level. The study involved 218 patients with type 2 diabetes (68.8% of females and 31.19% of males) who reported to the Outpatient Department for Diabetes at the Institute of Agricultural Medicine in Lublin. All patients were asked to complete a questionnaire form containing questions concerning, among other things, demographic data, course of diabetes, method of treatment, ability to adjust insulin doses and frequency of self-monitoring of blood glucose level. The levels of glycosylated emoglobin were obtained based on medical records. The analysis of the data showed that 59.22% of patients tested their blood glucose levels at home > or = 1/day, 21.36% of them tested their blood glucose > or = 1/week, whereas 8.74% of patients tested glucose < or = 1/week. 10.68% of patients stated that they never racticed SMBG. Statistical differences were observed in the level of education. Among the group of patients who exercised self-monitoring the most dominant were those with secondary school or university level of education (60.66%), while among patients who did not maintain self-monitoring the greatest number had only elementary or vocational education (72.73) (p = 0.01). The greatest number of patients who most often maintained self-monitoring were office workers (52.46%), whereas among those who did not exercise self-monitoring, those employed in agriculture dominated (45.45%) (p < 0.01). Urban inhabitants exercised self-monitoring more frequently than urban inhabitants (p < 0.01). The frequency of self-monitoring did not affect glycemia control. Urban inhabitants with secondary school or university education level and those who perform office work are more keen on frequent home monitoring of glycemia. In patients with type 2 diabetes the intensity of self-monitoring does not exert any effect on diabetes control evaluated by means of glycosylated hemoglobin level.
