Weight changes and sleep organisation in infants

I Fagioli, C Ricour, F Salomon

    Early Human Development
    |September 1, 1981
    PubMed
    Summary

    Infant sleep patterns, including ambiguous sleep and cycle length, correlate with 24-hour weight changes. This finding is crucial for understanding infant weight variations beyond clinical factors and caloric intake.

    Area of Science:

    • Pediatrics
    • Sleep Medicine
    • Infant Development

    Background:

    • Infant weight gain is a key indicator of health.
    • Sleep is a critical physiological process in infants.
    • Factors influencing infant weight gain require further investigation.

    Purpose of the Study:

    • To investigate the relationship between infant weight changes and sleep parameters.
    • To explore potential correlations between sleep architecture and weight fluctuations in infants.

    Main Methods:

    • Studied 26 infants aged 2-11 months over a 24-hour period.
    • Utilized polygraphic recordings to assess sleep stages and cycles.
    • Measured percentage of weight change within 24 hours.

    Main Results:

    • Significant correlations were found between 24-hour weight changes and total ambiguous sleep.
    • The percentage of time spent in sleep cycles and mean sleep cycle length also showed correlations with weight changes.

    Conclusions:

    • Infant sleep parameters, specifically ambiguous sleep and cycle characteristics, are associated with short-term weight changes.
    • These sleep-weight relationships may offer insights into unexplained infant weight variations, complementing clinical assessments and caloric intake data.
