A new RJ index, derived from mid-upper arm circumference and height, accurately estimates preschool children's weight. This simple anthropometric tool offers a significant advancement for nutritional assessment in community health surveys.

Area of Science:

  • Pediatric Nutrition
  • Community Medicine
  • Anthropometry

Background:

  • Accurate weight estimation is crucial for assessing the nutritional status of preschool children.
  • Traditional methods may be cumbersome in large-scale community health surveys.
  • Exploring novel anthropometric indices can improve screening efficiency.

Purpose of the Study:

  • To develop and validate a new index (RJ index) for estimating the weight of preschool children.
  • To assess the correlation between the proposed RJ index and weight-for-age.
  • To establish a predictive model for weight based on the RJ index.

Main Methods:

  • Screened 204 children aged 3 months to 5 years and 3 months.
  • Developed the RJ index: Mid-upper Arm Circumference x (Height)^2 x 10^-4.

Related Experiment Videos

  • Correlated the RJ index with weight-for-age using statistical analysis.

    • Main Results:

    • A highly significant correlation (r = 0.8, P < 0.001) was found between the RJ index and weight-for-age.
    • The proposed model Weight = A x exp (RJ x B) demonstrated a good fit with the collected data.
    • The RJ index shows promise as a reliable tool for weight estimation.

    Conclusions:

    • The RJ index, utilizing mid-upper arm circumference and height, is a significant and valid tool for estimating preschool children's weight.
    • This anthropometric index offers a practical alternative for weight assessment in community-based child health programs.
    • Further validation in diverse populations is recommended to establish its widespread utility.
