At younger ages, chronic kidney disease (CKD) is a progressive disorder associated with an increased risk for end-stage renal disease (ESRD). Older individuals with CKD are 10 to 20 times more likely to die than progress to ESRD. We hypothesized that, among individuals with CKD, the association between traditional cardiovascular risk factors with mortality would be weaker and the association between psychosocial risk factors with mortality would be stronger for individuals ≥ 75 years of age compared to those < 75 years of age. We included 5,924 REasons for Geographic And Racial Differences in Stroke (REGARDS) study participants with CKD without ESRD at baseline. CKD was defined as an albumin-to-creatinine ratio ≥ 30 mg/g or an estimated glomerular filtration rate < 60 mL/min/1.73m2. The 12-item Short Form Health Survey (SF-12) was administered and low physical and mental component scores (PCS and MCS) were defined as scores in the lowest quintile. Mortality was assessed through biannual telephone follow-up and contact with proxies provided by the study participant upon recruitment. Date of death was confirmed through death certificates, National Death Index, or Social Security Death Index. Over a median follow-up of 5.0 years, 1,255 deaths occurred. The mortality rate was 30.9 (95% CI: 28.6 - 33.4) and 74.8 (95% CI: 69.2 - 80.8) per 1,000 person-years for individuals < 75 years and ≥ 75 years of age, respectively. Diabetes, history of stroke, and systolic blood pressure were associated with an increased risk for mortality among individuals < 75 years of age but not among those ≥ 75 years of age (Table 1). Low PCS was associated with a higher risk for mortality for both younger and older adults. Symptoms of depression and low MCS were not associated with mortality in either age group. In conclusion, some cardiovascular risk factors are associated with an increased risk for mortality among younger but not older individuals with CKD. These data suggest approaches to reduce mortality risk may differ for younger and older adults with CKD.

Cortical Response

Cardiovascular fitness is linked to better executive functions, preserved gait speed, and efficient cortical activity. Older adults with cardiovascular risk factors (CVRFs) typically show poor cognitive performance, low physical fitness, and altered brain functioning compared with healthy individuals. In the current study, the impact of regular physical activity on cognition, locomotion, and brain functions was explored in a cohort of older adults with low or high CVRFs. Cortical activation of the frontal areas was investigated using functional Near-Infrared Spectroscopy (fNIRS) at baseline, at 6 months and at 12 months. Evoked cortical response and behavioral performance were assessed using the dual-task walking paradigm, consisting of three conditions: single cognitive task (2-back task), single walking task (walking), and dual-task (2-back whilst walking). Results show greater task-related cortical response at baseline in individuals with high CVRFs compared to those with low CVRFs. Moreover, participants with high CVRFs benefitted the most from participating in regular physical activity, as their cortical response decreased at the 12-month follow-up and became comparable to that of participants with low CVRFs. These changes were observed in conjunction with improved cognitive performance and stable gait speed throughout the 12-month period in both groups. Our findings provide evidence that participation in regular physical activity may be especially beneficial in individuals with CVRFs by promoting brain and cognitive health, thus potentially contributing to prevention of cognitive decline. Future research may explore whether such effects are maintained in the long-term in order to design ad-hoc interventions in this specific population.

Mild cognitive impairment (MCI) (amnestic or non-amnestic) has different clinical and neuropsychological characteristics, and its evolution is heterogeneous. Cardiovascular risk factors (CVRF), such as hypertension, diabetes, or dyslipidemia, and the presence of the Apolipoprotein E ε4 (ApoE ε4) polymorphism have been associated with an increased risk of developing Alzheimer’s disease (AD) and other dementias but the relationship is inconsistent worldwide. We aimed to establish the association between the ApoE ε4 carrier status and CVRF on MCI subtypes (amnestic and non-amnestic) in Mexican older adults. Cross-sectional study including 137 older adults (n = 63 with normal cognition (NC), n = 24 with amnesic, and n = 50 with non-amnesic MCI). Multinomial logistic regression models were performed in order to determine the association between ApoE ε4 polymorphism carrier and CVRF on amnestic and non-amnestic-MCI. ApoE ε4 carrier status was present in 28.8% participants. The models showed that ApoE ε4 carrier status was not associated neither aMCI nor naMCI condition. The interaction term ApoE ε4 × CVRF was not statistically significant for both types of MCI. However, CVRF were associated with both types of MCI and the association remained statistically significant after adjustment by sex, age, and education level. The carrier status of the ApoE genotype does not contribute to this risk.
