Changes in relative weight among institutionalized elderly adults.

J T Dwyer, K A Coleman, E Krall

    Journal of Gerontology
    |May 1, 1987
    PubMed
    Summary

    Weight fluctuations are common in elderly care residents. Significant weight loss over two years is linked to a lower survival rate, highlighting the importance of individual monitoring.

    Area of Science:

    • Gerontology
    • Geriatric Medicine
    • Nutritional Science

    Background:

    • Assessing nutritional status in institutionalized elderly is crucial for health outcomes.
    • Existing weight-for-height standards may not accurately reflect the elderly population.
    • Significant weight changes can occur despite stable group averages.

    Purpose of the Study:

    • To describe weight-for-height and weight changes in institutionalized elderly adults over two years.
    • To compare admission weight-for-height with current standards.
    • To investigate the association between weight changes and long-term survival.

    Main Methods:

    • Retrospective analysis of weight data for 335 institutionalized elderly adults.
    • Comparison of admission weight-for-height to multiple established standards.

  • Tracking weight changes over a 2-year period and correlating with 4-year survival data.

    • Main Results:

    • Proportions of underweight and obese individuals varied based on the standard used.
    • While group mean weights showed little change, 73% of individuals experienced significant weight shifts (≥4.5 kg).
    • A statistically significant lower 4-year survival rate was observed in patients with ≥4.5 kg weight loss compared to those with stable or increased weight.

    Conclusions:

    • Weight fluctuations are prevalent in institutionalized elderly, potentially underestimated by group analyses.
    • Individual weight monitoring is a simple yet meaningful indicator of health status.
    • Weight loss in this population is a significant predictor of mortality, underscoring the need for age-appropriate assessment tools.
