Intensified treatment consisted of pharmacological treatment combined with lifestyle education to achieve haemoglobin A1c (HbA1c) <7.0%, blood pressure <135/85 mmHg, and cholesterol <5.0 mmol/l (4.5 mmol/l if cardiovascular disease was present). Health-related quality of life (HRQoL) was assessed using the Short Form (SF)-36. Analyses were performed using generalised estimating equations models.Results Changes in body mass index were 0.2 (routine care) versus −1.4 kg/m2 (intensified treatment), P<0.001; systolic blood pressure −19 versus −33 mmHg, P<0.001; diastolic blood pressure −7 versus −12 mmHg, P<0.001; HbA1c −0.9% versus −1.1%, P = 0.03; cholesterol −0.5 versus −1.2 mmol/l, P<0.001; high-density lipoprotein cholesterol 0.1 versus 0.1 mmol/l, P = 0.26; low-density lipoprotein cholesterol −0.5 versus −1.0 mmol/l, P<0.001; triglycerides −0.3 versus −0.4 mmol/l, P = 0.71. No difference in HRQoL between the two groups was reported.Conclusion Intensified multifactorial treatment of patients with screen-detected diabetes in general practice reduces cardiovascular risk factor levels significantly without worsening HRQoL.
