Aims To compare (i) the prevalence and incidence of chronic complications and (ii) cardiac and all-cause mortality in community-based patients with latent autoimmune diabetes in adults (LADA) with those in Type 2 diabetic patients without antibodies to glutamic acid decarboxylase (GAD).

Methods Of the 1294 patients with clinically-defined Type 2 diabetes recruited to the longitudinal, observational Fremantle Diabetes Study between 1993 and 1996, 1255 (97%) had GAD antibodies measured at baseline. Complications were ascertained using standard criteria in patients returning for annual assessments until November 2001. Data on hospital admissions and mortality were available to the end of June 2006. Cox proportional hazards modelling was used to determine independent predictors of first occurrence of complications and cardiac and all-cause mortality.

Results Forty-five (3.6%) subjects had LADA. Compared with the GAD antibody-negative patients, they had a similar prevalence and incidence of coronary heart (P = 0.48 and 0.80, respectively) and cerebrovascular (P = 0.64 and 0.29) disease and cardiac and all-cause mortality (P = 0.62 and 0.81, respectively). There was also a similar prevalence and incidence of retinopathy (P = 0.22 and 0.64, respectively) and neuropathy (P = 0.25 and 0.95), but microalbuminuria was less frequent both at baseline and during follow-up in the LADA subgroup in unadjusted models (P = 0.046) and after adjustment for other risk factors (P = 0.014 and 0.013).

Conclusions Except for a lower prevalence and incidence of nephropathy, LADA patients have a similar risk of complications and death to patients with clinically-diagnosed Type 2 diabetes without GAD antibodies. Cardiovascular risk factor management in LADA should, therefore, be as intensive as that for GAD antibody-negative patients.

Aims

To determine whether the personality traits of conscientiousness and agreeableness are associated with self-care behaviours and glycaemia in Type 2 diabetes.

Methods

The Big Five Inventory personality traits Agreeableness, Conscientiousness, Extraversion, Neuroticism and Openness were determined along with a range of other variables in 1313 participants with Type 2 diabetes (mean age 65.8 ± 11.1 years; 52.9% men) undertaking their baseline assessment as part of the community-based longitudinal observational Fremantle Diabetes Study Phase II. Age- and sex-adjusted generalized linear modelling was used to determine whether personality was associated with BMI, smoking, self-monitoring of blood glucose and medication taking. Multivariable regression was used to investigate which traits were independently associated with these self-care behaviours and HbA1c.

Results

Patients with higher conscientiousness were less likely to be obese or smoke, and more likely to perform self-monitoring of blood glucose and take their medications (P ≤ 0.019), with similar independent associations in multivariate models (P ≤ 0.024). HbA1c was independently associated with younger age, indigenous ethnicity, higher BMI, longer diabetes duration, diabetes treatment, self-monitoring of blood glucose (negatively) and less medication taking (P ≤ 0.009), but no personality trait added to the model.

Conclusions

Although there was no independent association between personality traits and HbA1c, the relationship between high conscientiousness and low BMI and beneficial self-care behaviours suggests an indirect positive effect on glycaemia. Conscientiousness could be augmented by the use of impulse control training as part of diabetes management.
