Alternative anthropometric indicators of mortality.

R Bairagi, M K Chowdhury, Y J Kim

    The American Journal of Clinical Nutrition
    |August 1, 1985
    PubMed
    Summary

    Anthropometric indicators like weight-for-age and height-for-age effectively predict child mortality over one year. Weight velocity shows promise for identifying short-term mortality risks in young children.

    Area of Science:

    • Pediatric Nutrition
    • Public Health
    • Biostatistics

    Background:

    • Child mortality remains a significant global health challenge, particularly in developing regions.
    • Anthropometric indicators are commonly used to assess child growth and nutritional status.
    • Identifying reliable predictors of mortality is crucial for timely interventions.

    Purpose of the Study:

    • To evaluate the effectiveness of various anthropometric indicators in discriminating mortality among children aged 1-4 years.
    • To compare the predictive power of static indicators (weight-for-age, height-for-age, weight-for-height) versus dynamic indicators (weight velocity, height velocity).
    • To assess the utility of these indicators across different seasonal time frames.

    Main Methods:

    • Analysis of data from approximately 1,000 children (1-4 years) in Matlab, Bangladesh.

  • Assessment of mortality-discriminating power using standard deviation differences between living and deceased children's indicator values.
  • Evaluation of maximum sensitivity and specificity, and visual representation of mortality curves by nutritional status.
  • Statistical significance tested using the t-test.
  • Main Results:

    • Weight-for-age and height-for-age demonstrated superior ability to discriminate one-year mortality compared to weight velocity and height velocity.
    • Weight velocity showed potential as a good indicator for short-term mortality prediction.
    • The discriminating power varied slightly depending on the starting season of the assessment period.

    Conclusions:

    • Weight-for-age and height-for-age are robust indicators for predicting one-year child mortality.
    • Weight velocity holds promise for identifying children at imminent risk of short-term mortality.
    • Anthropometric indicators provide valuable insights into child survival, with distinct roles for long-term and short-term risk assessment.
