Insights

Iranian infants require local growth charts. Current National Centre for Health Statistics (NCHS) data is misleading, showing significant differences compared to new Shiraz-based charts, especially after six months.

Area of Science:

  • Pediatrics
  • Anthropometry
  • Public Health

Background:

  • Growth monitoring in Iranian infants currently relies on non-local National Centre for Health Statistics (NCHS) reference data.
  • This reliance on external data is potentially misleading for accurate infant growth assessment in Iran.

Purpose of the Study:

  • To develop and present local growth charts for length and weight for Iranian infants.
  • To compare these new local charts with existing NCHS reference data.

Main Methods:

  • A cohort of 317 infants (164 girls, 153 boys) born in Shiraz, Southern Iran, in 1996 was followed for two years.
  • Length and weight measurements were collected and analyzed to generate centile charts.

Main Results:

  • The developed Iranian infant growth charts show centiles slightly above NCHS charts before six months of age.
  • After six months, the local charts fall substantially below NCHS charts, indicating significant differences.
  • The similar spread of the charts suggests no widespread gross malnutrition is indicated by the divergence.

Conclusions:

  • Locally derived growth charts are essential for accurate assessment of infant growth in Iran.
  • The presented charts are likely applicable to the urban infant population of Iran, improving growth monitoring accuracy.

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Exponential Equations for Modeling Growth

Exponential models are essential for describing rapid, multiplicative changes in natural systems, such as population growth. When a population doubles at regular intervals, the process can be modeled using a suitable base. For instance, a bacterial culture that doubles every three hours follows the model n(t)=n0⋅2t/3, where n(t) is the population at the time t.A more general model uses the natural base e, especially for continuous growth. This takes the form n(t)=n0⋅ert, where r is the relative...
