Clinical, randomized and prospective trial, without blinding, in two Basic Health Units in an inner city of the state of São Paulo. The study aims at evaluating the effects of an educative intervention over the Self-Monitoring of Blood Glucose (SMBG) at home for metabolic control. A total of 91 people with diabetes participated, recruited from the home capillary blood glycemia self-monitoring program. Two groups of participants were formed: one group participated in the SMBG program at home and with usual care (control group), while the other group participated in the SMBG at home and with educative intervention (intervention group). In total there were 12 meetings, three for each conversation map in the control of diabetes, during four months in 2011 and 2012. For the analysis, two non-parametric tests were used. Pearson’s chi square and Fisher’s exact tests were used for comparing proportions. On the other hand, the chisquare test of linear trend was used to evaluate the proportional trends of either increase or decrease between the ordinal variables. For all the analysis, a significance statistical level of 5% (p ≤ 0.05) was adopted. Similar characteristics could be observed when comparing the results of both groups. Most part of participants were females, married, with an average age of 62.1 years old and schooling from four to seven years of study. In the intervention group, an improvement was observed in the following measures: body mass index, abdominal circumference, diastolic blood pressure, fasting plasma glucose, HDL cholesterol, LDL cholesterol and triglycerides. The control group showed improvement in measures of systolic and diastolic blood pressure, fasting plasma glucose, HDL cholesterol and LDL cholesterol. Moreover, an increase on the values of glycated hemoglobin was observed in both groups. It was observed that there was not statistical significant improvement of the metabolic control. However, it was possible to confirm that an educative intervention for SMBG at home presented a clinical significance, which in turn, resonates in a special way on the health of participants. The study was registered with the Clinical Trials Registry under number NCT01475422.
