    Nearly 30% of healthy Black children aged 13-59 months showed lactose malabsorption. This common digestive issue in preschoolers did not correlate with socioeconomic status or milk intake.

    Area of Science:

    • Pediatric Nutrition
    • Gastroenterology
    • Human Physiology

    Background:

    • Lactose malabsorption is prevalent in various populations.
    • Understanding its occurrence in young children is crucial for dietary recommendations.
    • Socioeconomic factors may influence health outcomes, including digestive health.

    Purpose of the Study:

    • To determine the prevalence of lactose malabsorption in healthy Black children.
    • To investigate the relationship between lactose malabsorption and socioeconomic status.
    • To explore potential links between milk consumption patterns and lactose malabsorption.

    Main Methods:

    • A lactose tolerance test was administered to 116 healthy Black children (13-59 months).
    • Blood glucose levels were measured at intervals after lactose ingestion.

  • Clinical symptoms of malabsorption were recorded.

    • Main Results:

    • Lactose malabsorption was identified in 34% (29%) of the children.
    • Clinical signs like diarrhea and gas occurred in 18% of malabsorbers.
    • No significant association was found between malabsorption and socioeconomic status, infant feeding, or current milk intake.

    Conclusions:

    • Lactose malabsorption is common in young Black children, irrespective of socioeconomic background.
    • Dietary habits and socioeconomic factors do not appear to be primary drivers of lactose malabsorption in this cohort.
    • Further research may explore genetic predispositions or other environmental factors.
