Belonging to a diabetes patients’ association is predictive of better metabolic control

Abstract

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 a 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 β-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, antihypertensive and dyslipidaemic drug use was also similar, except for a 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 β-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.
