Summary
Poor odour perception and dental status are linked to lower nutrient intake in the elderly. These factors, especially reduced odour sensitivity, impact energy, water, and specific nutrient consumption in older adults.
Area of Science:
- Gerontology
- Nutritional Science
- Sensory Science
Background:
- Elderly populations often exhibit high rates of nutrient insufficiency.
- Reduced odour perception and poor dental health are common in older adults.
- These factors may influence dietary intake and nutritional status.
Purpose of the Study:
- To investigate the relationship between age, odour perception, dental status, and nutrient intake in independently living elderly individuals.
- To determine the specific impact of sensory and oral health on macronutrient and micronutrient consumption.
Main Methods:
- A cross-sectional study involving 119 independently living elderly participants (aged 60-90) in Belgium.
- Assessment of odour detection thresholds (isoamylacetate) and dental status.
- Analysis of 7-day food records to quantify nutrient intake using path analysis.
Main Results:
- Odour perception showed a significant association with intake of energy, water, iron, and niacin.
- Poor odour perception was linked to lower water intake.
- Dental status significantly affected intake of animal protein, niacin, and monounsaturated fats.
Conclusions:
- While not fully explaining nutrient intake variability, poor odour perception is associated with reduced nutrient intake in the elderly.
- Dental status may be a contributing factor to poor nutrition, particularly when combined with other risk factors.
- Sensory and oral health are important considerations for nutritional status in aging populations.
