The importance of preventing and controlling hypertension (HTN) and diabetes mellitus (DM) to mitigate risks to physical health has long been understood by healthcare professionals. More recently, a growing body of evidence also implicates HTN and DM in age-related cognitive decline and risk for dementia, though consensus has yet to be reached on whether older adults living with comorbid HTN and DM are at heightened risk for cognitive impairment. The present study sought to contribute to this topic through a coordinated analysis of three longitudinal studies of aging from England, Sweden, and the United States (total N=12 513). Identical multilevel linear growth models were fit to each to estimate the impact of baseline disease status on initial level and change in verbal declarative memory performance. Overall, few associations between HTN, DM and cognition were observed. Rate of decline was steeper for Swedish participants with independent HTN but attenuated for their American counterparts. Americans with comorbid HTN and DM showed attenuated decline. Treatment with medication was substantially less prevalent in the earlier-born and lower-educated Swedish sample, which may help to explain our pattern of results. In addition, those living with multiple conditions may be more likely to receive treatment, mitigating cognitive decline. Our results present a nuanced view of the interactions between HTN, DM and cognition and lead us to recommend consideration of treatment status or proxies such as birth cohort and education, in combination with age at assessment and specific measure used, in the interpretation of research in this area.
71.7% and 41.7%, respectively. MNA results showed that only 11.7% of the old man was in good nutrition, up to 68.3% was in potential risk of malnutrition and 20.0% was malnutrition. Staple foods, milk and products, vegetables and edible oil were 233.3g/ day, 46.5 g/day, 165.0 g/day and 6.4 g/day, respectively. Results of ADL survey showed that disabled accounted for 28.3%, and in which 58.9% of light disabled, 23.6% for moderate and 17.6% for severe disabled. Subjects of BMI<18.5kg/m 2 accounted for 36.6%, anemia, low-protein and low-albumin accounted for 56.7%,16.7% and 46.7%, respectively. From the MoCA Scale test, the declined cognitive abilities accounted for 48.1% totally. The correlation coefficient between cognitive score and staple foods, milk and products, beans, vegetables was 0.97, 0.90, 0.94 and 0.97 respectively. Conclusions:The nutrition and cognition ability in nursing homes was severe and more attention should be paid for improvement of nutrition prevention among older adults lived in nursing home.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
