Belonging to a diabetes patients' association is predictive of better metabolic control
2008
Aim. - Diabetes mellitus (DM) management requires the patient's involvement, but it is unknown whether belonging to a patient's association leads to better metabolic control. Methods. - A total of 323 type 1 (T1) and 494 type 2 (T2) outpatient diabetics were analyzed according to whether or not they were members of it diabetes patients' association. Results. -T1 members (M: N=138) were older and had longer diabetes durations than non-members (nM; N= 185). Both groups had similar BP, kidney function, lipid profile. BMI and socioeducational status. HbA(1c) (means +/- SD) were lower in M than in nM: 8.1 +/- 1.2% versus 8.4 +/- 1.4%, respectively; P<0.04. T1 M practised more frequent self-monitoring of blood glucose (SMBG). T2 M (N=97) were also older and had longer diabetes durations than nM (N=397), and both groups had similar BP, kidney function, BMI and socioeducational status. Although M had lower HOMA beta-cell function (50.6 +/- 31.5% versus 63.5 +/- 44.3% P<0.01), they had a similar HbA(1c) and a better lipid profile. T2 M practised more frequent SMBG and were more likely to use insulin. Oral antidiabetic, anti hypertensive and dyslipidaemic drug use was also similar, except fora higher use of calcium-channel blockers in T2 M. Conclusion. - Belonging to a patients' organization was associated with better HbA(1c) in T1DM. In T2DM, which progresses relentlessly, similar HbA(1c) levels and better lipid profiles were observed, despite longer known disease durations and lower beta-cell function. These were not explained by gender. clinical. renal. therapeutic or educational parameters, but might reflect more responsibility, empowerment and/or compliance in terms of the condition or its management.
