Poor dentition and chewing ability in older men are linked to lower nutrient intake. Maintaining teeth and using dentures can improve diet quality.

Area of Science:

  • Gerontology
  • Nutritional Science
  • Dental Public Health

Background:

  • Tooth loss and impaired masticatory function are common in older adults.
  • Dietary habits significantly impact overall health and well-being in aging populations.

Purpose of the Study:

  • To investigate the association between oral health status (dentition, masticatory function) and nutrient intake in older men.
  • To determine if impaired dentition or reduced chewing ability affects the quality of diet.

Main Methods:

  • Analysis of dietary intake and oral health data from 638 men participating in the U.S. Department of Veterans Affairs Dental Longitudinal Study.
  • Statistical adjustments for age, smoking status, and alcohol consumption were applied.

Main Results:

  • Calorie-adjusted nutrient intake decreased with worsening dentition status, independent of other lifestyle factors.
  • Reduced masticatory function showed an inverse correlation with the intake of fiber, vitamins, and minerals.

Conclusions:

  • Tooth loss and poor chewing function are associated with poorer nutrient intake in older men.
  • Preventive dental care and effective prosthodontic solutions may play a crucial role in improving the nutritional status of the elderly.
