    Summary

    Swedish children exhibit advanced skeletal development compared to British children, with similar ossification patterns observed across Swedish studies, indicating a secular trend. This longitudinal study tracked 212 urban children

    Area of Science:

    • Pediatric skeletal development
    • Human growth and development studies
    • Anthropometry and biostatistics

    Background:

    • Longitudinal growth studies are crucial for understanding developmental trajectories.
    • Skeletal ossification timing is a key indicator of biological maturation.
    • Secular trends in growth and development have been observed globally.

    Purpose of the Study:

    • To investigate skeletal development in a cohort of Swedish urban children.
    • To compare ossification timing with previous Swedish and international growth studies.
    • To identify secular trends and sex-specific differences in skeletal maturation.

    Main Methods:

    • Prospective longitudinal study design involving 212 Swedish urban children.
    • Radiographic assessment of hand and wrist ossification at specified ages.

    Related Experiment Videos

  • Analysis of 2,191 radiographs up to seven years of age.

    • Main Results:

    • A secular trend in the timing of first ossification was identified compared to older Swedish data.
    • Ossification patterns showed high similarity between two Swedish investigations, differing from a North American study.
    • Swedish children demonstrated advanced skeletal development compared to British children, particularly in epiphyseal bones.

    Conclusions:

    • Swedish children's skeletal development shows a secular trend and advanced maturation relative to British children.
    • Consistent ossification patterns across Swedish studies suggest reliable regional developmental norms.
    • Relative sex differences in ossification are comparable between Swedish and North American populations.
