Dietary patterns and multiple chronic diseases in older adults

Area of Science:

• Gerontology
• Nutritional Science
• Chronic Disease Epidemiology

Background:

• High prevalence of multiple chronic diseases in the elderly population.
• Significant health and financial burden associated with chronic conditions in older adults.
• Dietary patterns play a crucial role in managing multiple chronic diseases.

Purpose of the Study:

• Identify specific dietary patterns linked to multiple chronic diseases in older adults.
• Investigate the association between identified dietary patterns and comorbidity clusters.
• Provide evidence-based dietary recommendations for elderly health management.

Main Methods:

• Utilized two non-consecutive 24-hour dietary recalls for intake assessment.
• Defined multiple chronic diseases as two or more conditions from a list including dyslipidemia, hypertension, CKD, sleep disorders, diabetes, depression, and cognitive impairment.
• Employed latent class analysis for disease type identification and two-step cluster analysis for dietary pattern determination, followed by logistic regression.

Main Results:

• Identified three distinct dietary patterns and three clusters of multiple chronic diseases.
• The HLMVF dietary pattern showed a significant reduction in cardiometabolic cognitive impairment comorbidity (CCC) (OR=0.41).
• The HLMVF pattern also demonstrated a significant reduction in the especially sleep disorders comorbidity (ESC) (OR=0.34).

Conclusions:

• The HLMVF dietary pattern is a potentially protective eating style for older adults.
• Promoting the HLMVF dietary pattern may help decrease the incidence of multiple chronic diseases.
• This dietary approach offers a strategy for improving health outcomes in the elderly population.
