  Aims  Obesity is linked to increased morbidity and mortality risk in both the general population and in patients with diabetes mellitus; however, recent reports suggest that, in hospitalized elderly individuals, the association between body mass index (BMI) and mortality may be inverse. The present study sought to investigate the association between BMI and survival in hospitalized elderly individuals with diabetes mellitus.

Methods  The medical records of 470 patients (226 males, mean age of 81.5 ± 7.0 years) admitted to an acute geriatric ward between 1999 and 2000 were reviewed. Of the 140 patients with diabetes mellitus, 122 had more than 6 months of follow-up and were included in this analysis. Patients were followed up until 31 August 2004. Mortality data were extracted from death certificates.

Results  During a mean follow-up of 3.7 ± 1.6 years, 69 (56.6%) subjects died, 31 (25.4%) from cardiovascular causes. Those who died from any cause had lower baseline BMI than those who survived (24.0 ± 4.0 vs. 27.1 ± 4.3 kg/m2; < 0.0001). Similarly, those who died of cardiovascular causes had lower baseline BMI than those who did not (23.7 ± 3.6 vs. 25.9 ± 4.5, = 0.01). BMI was inversely associated with all-cause [relative risk (RR) 0.89, 95% confidence interval (CI) 0.83-0.96, P = 0.002] and cardiovascular death (RR 0.83, 95% CI 0.74-0.93, P = 0.002) even after controlling for age, sex, smoking, dyslipidaemia and reason for hospital admission.

Conclusions  In very elderly subjects with diabetes mellitus, increased BMI was associated with reduced mortality risk.

  Aims  Obesity is associated with inflammation. Anti-inflammatory interventions such as aspirin and statins (anti-IFRx) might be a novel approach to the treatment of obesity and Type 2 diabetes mellitus (T2DM). The present study was designed to determine whether exposure to anti-IFRx is associated with weight loss in T2DM patients.

Methods  Exposure to anti-IFRx was compared between T2DM patients with a history of weight loss (n = 100) and those with no weight loss or with weight gain (n = 102) during a 1-year follow-up period. Logistic regression was used to develop odds ratios for weight loss status.

Results  Subjects who lost weight were more frequently exposed to anti-IFRx (85.0 vs. 71.5%, P = 0.018) than subjects who maintained or gained weight during follow-up. The 158 subjects exposed to anti-IFRx were older (64.2 ± 9.4 vs. 60.6 ± 11.2 years, P = 0.04), had longer duration T2DM (14.5 ± 9.5 vs. 9.0 ± 9.4 years, P = 0.001), had greater prevalence of dyslipidaemia (72 vs. 19%, P < 0.0001) hypertension (57.3 vs. 38.1%, P = 0.03) and cardiovascular disease (37.7 vs. 9.5%, P < 0.0001) than subjects not exposed to anti-IFRx. In a logistic regression model for weight change status, anti-IFRx exposure was significantly associated with weight status (odds ratio = 2.3, 95% confidence interval 1.1-4.8, P = 0.02, an association that persisted), even after controlling for age, sex, baseline body mass index, years since diagnosis, OHA therapy and co-morbidities.

Conclusions  Exposure to anti-IFRx more than doubled the odds of weight loss in T2DM patients. Results of this study justify a randomized clinical trial to determine definitively the role of anti-IFRx in weight loss in subjects with T2DM.
