Study the changing clinical and therapeutic profiles of type 2 diabetes (T2D) patients during a 10-year period in a diabetes care centre in Southern India.
Retrospective, cross-sectional data of newly registered and review patients at four periods between 2009 and 2018 were analysed (n = 50,322). Clinical findings, anthropometry, blood pressure (BP), glycaemia, lipids, treatment, and co-morbid conditions were analysed. We studied the trends in age and gender distributions, body mass index (BMI), glycaemia, (Glycosylated haemoglobin A1c (HbA1c) levels), BP, cholesterol, triglycerides and therapeutic regimen during this period. Trend analyses were done.
Approximately 60% of patients were men. Percentages in 30-40 years increased, ∼60% were aged 50-69 years and proportion of older patients decreased (p < 0.0001). In 10 years, 85.9% was overweight, obesity increased from 22.1% to 25.0% (p < 0.0001) and <13% maintained normal BMI. HbA1c <7.0% remained approximately at 22%, percentage with moderate glycaemic control (HbA1c 7.0-7.9%) increased significantly, HbA1c of ≥9.0% decreased from 35.1% to 29.1% (p < 0.0001). Use of monotherapy decreased. Prevalence of hypertension increased from 16.2% to 21.6% (p < 0.0001); use of Angiotensin Receptor Blockers (ARB) and calcium channel blockers increased, Angiotensin Converting Enzyme Inhibitors and thiazides decreased (p < 0.0001). Increased use of statins paralleled with reduction in total cholesterol and LDLc.
Increasing percentages of younger patients and obesity, use of multiple drugs and reduction in HbA1c were the important observations. Rising prevalence of hypertension, increased use of ARB and statins with better control of dyslipidaemia was observed. Achievement of ideal HbA1c and BP were suboptimal.
