The water load test helps determine when healthy children feel full. This study provides reference values for this simple test in elementary school students.

Area of Science:

  • Pediatric Nutrition
  • Gastroenterology

Background:

  • The water load test (WLT) is a method to assess gastric emptying and satiety.
  • Establishing normative data is crucial for clinical and research applications in pediatric populations.

Purpose of the Study:

  • To establish reference values for the water load test in healthy elementary school children.
  • To investigate factors influencing water consumption in this age group.

Main Methods:

  • 176 healthy elementary school children (71 boys, 105 girls) participated.
  • Children underwent the water load test, consuming water for 3 minutes or until full.
  • Questionnaires assessed self-efficacy and abdominal pain history.

Main Results:

  • Children consumed an average of 630 +/- 260 ml of water.

  • Water intake showed positive correlations with age, weight, and height.
  • Higher self-efficacy regarding drinking capacity was associated with greater water consumption (p < 0.01).

    • Conclusions:

    • The water load test is a feasible, simple, and cost-effective tool for estimating satiety onset in children.
    • Normative data from this study can aid future pediatric research.
    • Psychological factors like self-efficacy may influence fluid intake in children.
