Highlights
- •A third of type 2 diabetes patients had poor glycaemic control (HbA1c ≤58 mmol/mol).
- •Age, smoking, rural residence, time since diagnosis and polypharmacy increased risk.
- •The Morisky-Green Medication Adherence Scale showed a non-adherence of 34%.
- •Non-adherence was associated with low education and sedentarism.
Abstract
Aims
This study aimed to analyse the association between adherence to treatment and glycaemic
control in people with type 2 diabetes mellitus.
Methods
Multicentre, cross-sectional study in patients with type 2 diabetes mellitus recruited
by primary care professionals in Castilla y León (Spain). Sociodemographic and clinical
characteristics were reflected in self-reported questionnaire, which included the
Morisky-Green Medication Adherence Scale and the 14-point Mediterranean Diet Adherence
Screener. Medication non-adherence and poor glycaemic control were analysed by bivariable
and multivariable analyses.
Results
Of 3536 included patients, the 33.8% reported non-adherence to pharmacological treatment,
and the 33.7% had poor glycaemic control (HbA1c ≥58 mmol/mol [7.5%]); 50.6% of patients
reported moderate-high adherence to the Mediterranean diet (≥9 points). The multivariable
logistic regression model showed that educational level (OR 0.73; 95% CI 0.61-0.87;
p < 0.001) and sedentarism (OR 1.64; 95% CI 1.36−1.98; p < 0.001) were associate with
low adherence. Younger age, rural residence, smoking, time since diagnosis (OR 1.04;
95% CI 1.03−1.05; p < 0.001) and polypharmacy were associated with poor glycaemic
control.
Conclusion
Lower educational level and sedentarism were associated with low adherence. Younger
age, rural residence, smoking, time since diagnosis and polypharmacy, increased risk
of poor glycaemic control.
