Background And Aims:
Diabetes is a suitable model to evaluate intervention programmes aimed at chronic diseases, because of its well-defined and measurable process and outcome indicators. In this study, we aimed at investigating the effects of group based self-management education on clinical and psychological variables in type 2 diabetes.
Methods And Results:
Four-year randomized controlled clinical trial (ISRCTN14558376) comparing Group Care and traditional one-to-one care. Clinical and psychological variables were monitored at baseline, 2 and 4 years. Although differences between groups appear to be non-significant at univariate analysis, body weight, BMI and HbA1c, systolic and diastolic blood pressure improved in the patients followed by Group Care but not among Controls. Prescription of lipid-lowering and anti-hypertensive agents did not change among the patients on Group Care, whereas anti-hypertensives were stepped up among Controls without improving their blood pressure. Multivariable analysis suggests that blood pressure improvement among patients on Group Care was independent of BMI, duration of diabetes and antihypertensive medication, suggesting a direct effect of education, presumably by increasing adherence. The "Powerful Others" dimension of the Locus of Control worsened and fear of complications decreased among Controls.
Conclusions:
The results confirm that a multidisciplinary structured group educational approach improves blood pressure, presumably through better adherence to healthy lifestyle and medication, in people with type 2 diabetes.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...
