This study confirmed that the risk of mortality in individuals with type 1 diabetes remains elevated. Further studies are required to understand how gender affects the disparity in mortality and why obesity appears to be protective.

Aims/IntroductionThe increased mortality risk associated with diabetes is well established. The aim of the present study was to determine the causes of death of people with type 2 diabetes in Ayrshire and Arran, Scotland, between 2009 and 2014, and compare them with the national mortality rates.Materials and MethodsThe primary causes of death were collated. The causes of death were clustered into nine categories: heart disease, stroke, infection, renal failure, respiratory disorders, cancer, mental health, decompensated diabetes and other. The total rates were compared with national rates using the standardized mortality ratio (SMR), and then individually with heart disease, cerebrovascular disease and cancer.ResultsThere were 2116 deaths with the SMR, and 145 of those were caused by type 2 diabetes (n = 16,643; 95% confidence interval 139–152; P < 0.01). The SMR was >100 in all age bands, particularly in the younger age bands (P < 0.01). The SMR was consistently higher for women (P < 0.01). The SMR for heart disease was significantly >100 for both sexes in all age bands <65 years (P < 0.05). There was no difference in mortality causes related to the duration of diabetes. The most common cause of death was cancer (27.8%), followed by heart disease (24.1%). The SMR for cancer deaths was significantly elevated in women (120, 95% CI 104–137; P < 0.05).ConclusionsThis study confirmed increased mortality risk in type 2 diabetes patients, and suggests that where cardiovascular risk factors are being treated aggressively, cancer takes on a greater importance in the cause of death. Should greater consideration now be given for cancer as a complication of diabetes?

The aims of this cross-sectional study were to compare metabolic parameters in people with gout and diabetes with gout only and type 2 diabetes mellitus (T2DM) only. Fifty General Practices in NHS Ayrshire and Arran (population 340 377) contributed data. The sample was split into three groups, those with both gout and T2DM, those with gout only and those with T2DM only. The prevalence of gout in Ayrshire and Arran was 2.65%. The prevalence of gout in people with type 1 and 2 diabetes was 1.90% (p=0.30) and 10.12% (p<10(-5)), respectively. Patients with both conditions were significantly more likely to be male (p<10(-5)), older (p<10(-5)), have a higher mean body mass index (p<0.001), higher triglycerides (p<10(-4)), lower mean total, high-density lipoprotein- and low-density lipoprotein cholesterol (p<10(-5)), lower estimated glomerular filtration rate (p<0.001), neuropathy (p=0.02), lower haemoglobin (p<0.001), to be prescribed more medications (p<10(-5)) and less likely to smoke (p<0.01). There was an association between lower haemoglobin A1c and increased prevalence of gout (p<0.001). 42.4% of patients with gout alone and 36.2% of those with both gout and diabetes had a urate measure. This study defines much more clearly the association between gout and T2DM. Of interest, in terms of lifestyle, both better glycaemic control and smoking are associated with a higher prevalence of gout.

Abstract BackgroundThe aims of this study were to investigate the effects of age, gender, body mass index (BMI), glycaemic control, socio-economic status, dyslipidaemia, hypertension, ischaemic heart disease (IHD) and smoking status in type 2 diabetes in a population-based analysis. MethodsData were collected from 46 General Practice databases in 2009 and 2014. Cox regressions were run in the non-diabetes population plus type 2 diabetes patients. ResultsPeople with type 2 diabetes (n=16,643) had higher mortality rates than non-diabetes subjects. Ranked in order of Hazard Ratio (HR), increasing age (HR 2.31), smoking (HR 1.79), IHD (HR 1.65), deprivation (HR 1.36), hypertension (HR 1.23) and male gender (HR 1.20) all increased mortality risk (p<0.01). Statin therapy was associated with better outcome (HR 0.65, p<0.01). Abnormal lipid levels whilst not on a statin significantly increased mortality risk for raised total-cholesterol (HR 1.74) and low HDL-cholesterol (HR 1.48) but not for triglycerides (HR 0.67) (all p<0.01). ConclusionsThis large study confirmed that the all-cause mortality risk in people with type 2 diabetes remains elevated. In the study we demonstrated that a man with type 2 diabetes of 5-10 years duration who smoked, had hypertension and IHD plus lived in the most deprived area had a HR of 6.2 compared with a non-smoking, normotensive, non-diabetes subject without IHD living in the least deprived area. . Further research is required to understand the gender risk difference in all-cause mortality in type 1 compared with type 2 diabetes and why obesity plus raised triglycerides appear to be protective.
