Dietary patterns among older Europeans: the EPIC-Elderly study.

Area of Science:

• Gerontology
• Nutritional Epidemiology
• Public Health

Background:

• Dietary patterns significantly influence health outcomes and longevity in older adults.
• Understanding these patterns is crucial for targeted public health interventions.
• Previous research highlights the link between diet and aging well.

Purpose of the Study:

• To identify prevalent dietary patterns among elderly Europeans using advanced statistical methods.
• To examine the socio-demographic and lifestyle factors associated with these dietary patterns.
• To explore geographical variations in dietary habits across Europe in the aging population.

Main Methods:

• Utilized principal component (PC) and cluster analyses on data from 99,744 participants (aged 60+) in the EPIC-Elderly cohort.
• Defined two key dietary patterns: PC1 (vegetable-based) and PC2 (sweet- and fat-dominated).
• Analyzed correlations between dietary patterns and participant characteristics (age, education, BMI, physical activity, smoking status, waist:hip ratio).

Main Results:

• PC1 (vegetable-based) associated with younger age, higher education, physical activity, higher BMI, lower waist:hip ratio, and non-smoking history.
• PC2 (sweet- and fat-dominated) associated with older age, less education, never smoking, lower BMI, lower waist:hip ratio, and less physical activity.
• Elderly in Southern Europe favored PC1, while Northern Europeans showed varied patterns, indicating a significant north-south dietary gradient.

Conclusions:

• Prevalence of 'vegetable-based' and 'sweet- and fat-dominated' diets identified in European elderly.
• Significant north-south gradient observed in dietary choices among the elderly population.
• These dietary patterns likely influence long-term disease risk and survival in older adults, informing future health strategies.
