Birth size significantly impacts adult height, with early catch-up growth crucial. Defining small for gestational age (SGA) and socio-economic factors influence growth trajectories.

Area of Science:

  • Pediatrics
  • Human Growth and Development
  • Public Health

Background:

  • Strong correlation exists between birth size and adult height.
  • Variations in catch-up growth incidence and final height are reported across studies and countries.
  • Methodological issues may contribute to observed variations in growth outcomes.

Purpose of the Study:

  • To investigate the definition of small for gestational age (SGA) and its impact on postnatal growth.
  • To explore the influence of socio-economic status on early life growth faltering.
  • To analyze catch-up growth patterns after disturbed fetal growth.

Main Methods:

  • Analysis of two longitudinal, population-based studies from Sweden and Hong Kong.
  • Inclusion of birth length data and socio-economic status indicators.

  • Application of Swedish reference values for defining small for gestational age (SGA).

    • Main Results:

    • A significant proportion of infants were classified as small for gestational age (SGA) in both populations (3.8% in Sweden, 11.9% in Hong Kong).
    • The difference in birth length between extreme groups persisted until maturity.
    • Catch-up growth rates were highly dependent on the SGA definition and early growth patterns.

    Conclusions:

    • Birth size is a critical determinant of postnatal growth and final height.
    • The definition of small for gestational age (SGA) significantly affects the assessment of catch-up growth.
    • Socio-economic status and early life growth faltering are important factors influencing growth trajectories.
