Background: There is emerging evidence of the role of diabetes as a risk factor for frailty. However, the mechanisms of this association are uncertain. Methods: Prospective cohort study of 1750 non-institutionalized individuals aged ≥60 years recruited in 2008-2010. At baseline, information was obtained on health behaviors, morbidity, cardiometabolic biomarkers, and antidiabetic treatments. Individuals were considered diabetic if they reported a physician-diagnosis or had fasting serum glucose ≥126 mg/dl. Study participants were followed-up through 2012 to assess incident frailty, defined as at least three of the five Fried criteria. Results: At baseline, the cohort included 346 individuals with diabetes and 1404 without it. Over a mean 3.5-year follow-up, 115 cases of incident frailty were ascertained. After adjustment for age, sex and education, participants with diabetes showed an increased risk of frailty (odds ratio [OR]: 2.18; 95% confidence interval [CI]: 1.42-3.37). Additional adjustment for health behaviors and abdominal obesity yielded a 29.7% reduction in the OR (OR: 1.83; 95%CI: 1.16-2.90). Subsequent adjustment for morbidity produced an additional 8.4% reduction (OR: 1.76; 95%CI: 1.10-2.82), and for cardiometabolic biomarkers, a further 44% reduction (OR: 1.32; 95% 0.70-2.49). In particular, adjustment for HbA1c, lipoproteins and triglycerides accounted for the greatest reductions. Finally, additional adjustment for oral antidiabetic medication reduced the OR to 1.01 (95%CI: 0.46-2.20), while adjustment for nutritional therapy increased it to 1.64 (95%CI: 0.77-3.49). Conclusions: Diabetes mellitus is associated with higher risk of frailty; this association is partly explained by unhealthy behaviors and obesity and, to a greater extent, by poor glucose control and altered serum lipid profile among diabetic individuals. Conversely, diabetes nutritional therapy reduces the risk of frailty ; Baseline data collection was funded by Sanofi-Aventis. Data collection during follow-up was funded by the Spanish Government FIS grants 09/1626 and 09/0104 (Instituto de Salud Carlos III). Funding specific for this analysis was obtained from the Spanish Government FIS grant 12/1166 (Instituto de Salud Carlos III) and the FP7-HEALTH-2012-Proposal No: 305483–2 (FRAILOMIC Initiative).

Objective: We examined physician perception of blood pressure control and treatment behavior in patients with previous cardiovascular disease and uncontrolled hypertension as defined by European Guidelines. Methods: A cross-sectional study was conducted in which 321 primary care physicians throughout Spain consecutively studied 1,614 patients aged ≥18 years who had been diagnosed and treated for hypertension (blood pressure ≥140/90 mmHg), and had suffered a documented cardiovascular event. The mean value of three blood pressure measurements taken using standardized procedures was used for statistical analysis. Results: Mean blood pressure was 143.4/84.9 mmHg, and only 11.6% of these cardiovascular patients were controlled according to 2007 European Guidelines for Hypertension Management target of <130/80 mmHg. In 702 (49.2%) of the 1426 uncontrolled patients, antihypertensive medication was not changed, and in 480 (68.4%) of these cases this was due to the physicianś judgment that blood pressure was adequately controlled. In 320 (66.7%) of the latter patients, blood pressure was 130-139/80-89 mmHg. Blood pressure level was the main factor associated (inversely) with no change in treatment due to physician perception of adequate control, irrespective of sociodemographic and clinical factors. Conclusions: Physicians do not change antihypertensive treatment in many uncontrolled cardiovascular patients because they considered it unnecessary, especially when the BP values are only slightly above the guideline target. It is possible that the guidelines may be correct, but there is also the possibility that the care by the physicians is appropriate since BP <130/80 mmHg is hard to achieve, and recent reviews suggest there is insufficient evidence to support such a low BP target ; Funding for this study was obtained from RECORDATI ESPAÑA, S.L through an unrestricted grant.
