    Developmental Medicine and Child Neurology

    Summary

    Infant motor development in Yucatan showed advanced fine motor skills but delayed walking compared to US norms. No significant differences were found across socio-cultural groups or between genders.

    Area of Science:

    • Pediatrics
    • Developmental Psychology
    • Anthropology

    Background:

    • Understanding infant motor development is crucial for early identification of potential issues.
    • Socio-cultural factors may influence developmental trajectories.
    • Cross-cultural comparisons provide insights into universal and culturally specific developmental patterns.

    Purpose of the Study:

    • To assess infant motor development in three socio-cultural groups in Yucatan, Mexico.
    • To compare motor development between genders and across different age points.
    • To evaluate the utility of the Denver Developmental Screening Test (DDST) against the Bayley Infant Motor Scale.

    Main Methods:

    • A total of 288 infants (8 per month of age, from 2 weeks to 1 year 2 weeks) were studied across three socio-cultural groups.
    • Infant motor development was assessed using the Denver Developmental Screening Test (DDST) and the Bayley Infant Motor Scale.
    • Data were analyzed for differences among groups, between genders, and in relation to age.

    Main Results:

    • No significant differences in motor development were observed among the three socio-cultural groups or between boys and girls.
    • Infant motor abilities increased with age.
    • Compared to US Bayley norms, fine motor coordination was advanced, but walking ability was delayed.

    Conclusions:

    • Socio-cultural background and gender did not significantly impact infant motor development in this Yucatan sample.
    • The DDST demonstrated limitations in detecting developmental delays when compared to the Bayley Infant Motor Scale.
    • Specific motor skills, like fine motor coordination and walking, may show differential development patterns influenced by environmental factors.
