Summary

Elderly hospitalized patients often have inadequate nutrient intake, with age significantly impacting energy, protein, and micronutrient consumption. Gender did not affect food intake in this study.

Area of Science:

  • Gerontology
  • Clinical Nutrition
  • Dietetics

Background:

  • Hospitalized medical patients are at risk for malnutrition.
  • Nutritional status can be influenced by age and gender.
  • Assessing nutrient intake is crucial for patient recovery.

Purpose of the Study:

  • To investigate the impact of age and gender on food and nutrient intake in hospitalized medical patients.
  • To identify specific nutrient deficiencies in elderly patients.

Main Methods:

  • Prospective study involving 21 hospitalized medical patients.
  • Precise weighing of food served and uneaten to determine nutrient ingestion.
  • Analysis of macronutrient and micronutrient intake during hospitalization.

Main Results:

  • 38% of patients had inadequate nutritional intake (<65% of requirements).
  • Elderly patients (>65 years) showed significantly lower energy and protein intake compared to younger patients.
  • Inadequate micronutrient intake was prevalent, particularly in the elderly (e.g., folate, zinc, magnesium, vitamin B-6).
  • Age and admission body weight predicted lower nutrient intake.

Conclusions:

  • Age is a significant factor in reduced food and nutrient intake among hospitalized medical patients.
  • Elderly patients are particularly vulnerable to deficiencies in energy, protein, and essential micronutrients.
  • Interventions to improve nutritional status in elderly hospitalized patients are warranted.
