The Relationship Between Cognitive Functioning and the JNC-8 Guidelines for Hypertension in Older Adults.

ABSTRACT:

Background

Guidelines for hypertension treatment by the Eighth Joint National Committee (JNC-8) in 2014 recommended a target systolic blood pressure (BP) of <150/<90 mmHg in persons older than 60 years, in contrast to the 2003 JNC-7 recommendations of systolic BP <140 mmHg. This study evaluated the implications of raising the BP target on cognitive functioning and conversion from normal cognition to mild cognitive impairment (MCI).

Methods

This was a longitudinal study of individuals older than 60 years enrolled in the NIH-NIA Alzheimer's Disease Centers. All had normal cognition at baseline. 453 participants were taking BP medications and had readings of <140/<90 mmHg at four annual visits (reference group). Two other groups consisted of participants with either systolic BP of 140-149 mmHg (n = 112) or ≥150 mmHg (n = 280) on three or four annual visits.

Results

Compared with the reference and the 140-149 mmHg groups, those with BP ≥150 mmHg exhibited poorer cognitive status by Year 4 on the Mini-Mental State Exam, and they had a higher risk of conversion to MCI. The 140-149 mmHg exhibited poorer performance than the reference group on domains assessing attention and executive functioning. In contrast, their performance was not significantly different from those with BP ≥150 mmHg.

Conclusions

Persons with BP ≥150 mmHg show a faster global cognitive decline and transition to MCI than those with lower BP readings. However, the poor cognitive performance in the attention and executive functioning domains for the 140-149 mmHg group indicates the need for further research evaluating the newer recommended cutoff.

Project description:ObjectivesTo describe aerobic physical activity among middle-aged and older adults by their self-reported cognitive decline and their receipt of informal care for declines in cognitive functioning and most common type of physical activity.DesignCross-sectional study using data from the 2011 Behavioral Risk Factor Surveillance System.SettingLandline and cellular telephone survey.Participants93,082 respondents aged 45 years and older from 21 US states in 2011.MeasurementsSubjective cognitive decline (SCD) was defined as experiencing confusion or memory loss that was happening more often or getting worse during the past 12 months. Regular care was defined as always, usually, or sometimes receiving care from family or friends because of SCD. Using the 2008 Physical Activity Guidelines for Americans, respondents were classified as being inactive, insufficiently active, or sufficiently active based on their reported aerobic exercise. We calculated weighted proportions and used chi-square tests for differences across categories by SCD status and receipt of care. We estimated the prevalence ratio (PR) for being inactive, insufficiently active, and sufficiently active using separate log-binomial regression models, adjusting for covariates.Results12.3% of respondents reported SCD and 23.1% of those with SCD received regular care. 29.6% (95%CI: 28.9-30.4) of respondents without SCD were inactive compared to 37.1% (95%CI: 34.7-39.5) of those with SCD who did not receive regular care and 50.2% (95%CI: 45.2-55.1) of those with SCD who received regular care. 52.4% (95%CI: 51.6-53.2) of respondents without SCD were sufficiently active compared to 46.4% (95%CI: 43.8-49.0) of respondents with SCD and received no regular care and 30.6% (95%CI: 26.1-35.6) of respondents with SCD who received regular care. After adjusting for demographic and health status differences, people receiving regular care for SCD had a significantly lower prevalence of meeting aerobic guidelines compared to people without SCD (PR=0.80, 95%CI: 0.69-0.93, p=0.005). The most prevalent physical activity was walking for adults aged ≥ 45 years old (41-52%) regardless of SCD status or receipt of care.ConclusionOverall, the prevalence of inactivity was high, especially among people with SCD. These findings suggest a need to increase activity among middle-aged and older adults, particularly those with SCD who receive care. Examining ways to increase walking, potentially by involving informal caregivers, could be a promising way for people with SCD to reduce inactivity and gain the health benefits associated with meeting physical activity guidelines.
