Snack patterns of older Europeans

Area of Science:

• Gerontology
• Nutritional Science
• Public Health

Background:

• Dietary habits significantly impact the health and well-being of older adults.
• Understanding specific eating patterns, such as snacking, is crucial for assessing nutritional status in aging populations.
• Previous research has highlighted variations in dietary intake among elderly individuals across different European regions.

Purpose of the Study:

• To characterize the snacking behaviors of older individuals in various European towns.
• To group subjects based on similar snacking patterns using cluster analysis.
• To investigate the contribution of different snack patterns to daily energy and micronutrient intake.

Main Methods:

• Utilized data from the 1993 Survey in Europe on Nutrition and the Elderly: A Concerted Action (SENECA) follow-up study.
• Collected food intake data via a 3-day estimated record method from 379 men and 428 women aged 74–79 years.
• Employed cluster analysis to identify distinct snacking patterns and calculated energy and micronutrient (calcium, iron, vitamins B1, B2, B6, C) intakes.

Main Results:

• Identified five distinct snacking patterns among older European adults.
• A large group of 'light snackers' exhibited low snack consumption and correspondingly low energy and micronutrient intake.
• Groups such as 'alcohol drinkers' and 'dairy snackers' showed high snack use with elevated energy and micronutrient intake, while 'fruit and vegetable snackers' and 'sweet drinkers' fell in between.

Conclusions:

• Snacking patterns among older adults are identifiable and correlate with varying levels of energy and micronutrient consumption.
• Recognizing these distinct snack patterns is vital for tailoring dietary recommendations to individual needs, particularly in populations where snacking contributes significantly to overall energy intake.
• Personalized dietary advice based on identified snack patterns can improve nutritional outcomes in the elderly.
