Abstract The association between cognitive impairment and physical frailty has been studied in older adults. The criteria degree of frailty may be keys to associated cognitive impairment. Objective: To analyze the association between cognitive impairment and the criteria for frailty. Methods: We cross-sectionally examined data from 667 older adults (≥60 years of age) from a study entitled ‘Variables associated to cognition in elderly caregivers’ involving patients in an urban and rural primary healthcare center. We defined cognitive impairment based on different groups of scores on the Mini Mental State Examination, and defined frailty and prefrailty using the criteria by the Cardiovascular Health Study. We performed multinomial regression models to analyze the association between levels of frailty and cognitive impairment. Results: Similar proportions of women (54.8%) and men (45.2%) participated in the study (mean age: 71 years old). We found cognitive impairment, prefrailty and frailty in 34, 54, and 24% of the participants, respectively. Concomitant cognitive impairment and frailty was found in 13% of them. The chances of cognitive impairment increased up to 330% (Odds Ratio [OR]: 4.3; 95% confidence interval [95%CI] 2.4‒7.7; p<0.001) among frail individuals, and 70% (OR: 1.7; 95%CI 1.0‒2.8; p=0.033) among prefrail individuals compared to robust/non-frail individuals. After controlling for age, education, place of residence and functional dependence, slowness and fatigue criteria were significantly associated with cognitive impairment. Conclusion: Older adults with frailty have a greater likelihood of concomitant cognitive impairment than prefrail and robust older adults. The prevalence of cognitive impairment and frailty is consistent with data reported in literature. The present findings contribute to the investigation of cognitive frailty.

Introduction: Covert brain infarction (CBI) and worsening white matter grade (WMG) on serial MRI are associated with increased risk for ischemic stroke and dementia. Hypothesis: We sought to evaluate the association of various measures of blood pressure and heart rate with these MRI findings. Methods: In the Cardiovascular Health Study, a longitudinal cohort study of cardiovascular disease in older adults, we used relative risk regression to assess the risk of incident CBI and worsening WMG associated with mean, variability, and trend in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) measured at four or more annual clinic visits between two brain MRIs. We included participants who underwent both brain MRIs and had no change in antihypertensive medication status, no CBI on the initial MRI, and no stroke before the follow-up MRI. Results: Among 897 eligible participants, incident CBI occurred in 15% and worsening WMG in 27%. Mean SBP mean was strongly associated with increased risk for incident CBI (RR per 10 mmHg 1.29; 95% CI, 1.13-1.47), and DBP mean was strongly associated with increased risk for worsening WMG (RR per 10 mmHg 1.43; 95% CI, 1.23-1.67). DBP variability may be associated with incident CBI (RR per 10 mmHg 1.71; 95% CI, 1.10-2.65), The HR measures were not associated with these MRI findings. Conclusions: Elevated mean levels of blood pressure contribute to covert cerebrovascular diseases. Control of mean blood pressure levels, even in older adults, remains a high priority for prevention of vascular brain injury.

Background: Fatty acid binding protein 4 (FABP4) is an adipokine that plays a role in lipid transport. Previous studies have reported that FABP4 may increase the risk of diabetes and exert negative inotropy on the myocardium. It is unknown whether plasma FABP4 is associated with the risk of sudden cardiac death (SCD). Objective: To test the hypothesis that plasma FABP4 is associated with a higher incidence of SCD in older adults and determine if diabetes status modifies this association. Methods: We prospectively analyzed data on 4,564 men and women aged 65+ years from the Cardiovascular Health Study. FABP4 was measured at baseline using ELISA and SCD events were adjudicated through review of medical records (inter-reviewer agreement of 88% and kappa of 0.74). We used Cox proportional hazards model to examine the association between FABP4 and SCD. Results: During a median follow up of 11.8 years, 146 new cases of SCD occurred. In a multivariable model adjusting for age, sex, race, clinic, education, glomerular filtration rate based on cystatin C, high-sensitive C-reactive protein, leisure time physical activity, hormone replacement therapy, alcohol intake, self-reported general health status, smoking, prevalent coronary heart disease, and prevalent heart failure, each higher standard deviation (SD) of plasma FABP4 was associated with a non-significant 14% (95% CI: -5% to 37%) higher risk of SCD. When stratified by prevalent diabetes status, FABP4 was associated with a higher risk of SCD in non-diabetic participants, [HR per SD of FABP4: 1.37 (95% CI: 1.11-1.67)] but not in diabetic participants [HR per SD of FABP4: 0.77 (95% CI: 0.52-1.15)], p for diabetes-FABP4 interaction was 0.026. Conclusion: A single measure of plasma FABP4 obtained later in life was associated with a higher risk of SCD among older adults without diabetes but not among those with diabetes. If confirmed in other studies, these data may point to novel mechanisms and opportunities for SCD prevention.
