What researchers measure

Primary outcomes

  1. Difference in the Urinary L:M Ratio Before and After the Intervention

    To initiate the test, each child drank a 100 ml sugar solution containing 5 g lactulose, 1 g mannitol, 1 g sucralose, and 10 g sucrose. Children remained at the village research site for 4 h after ingestion of the sugar solution, during which time all of the child's urine was collected in a sterile cup with 10 mg merthiolate added to limit the bacterial degradation of excreted sugars. The reported values for normal L:M range from 0.03 to 0.12. A value of ≥0.10 was chosen to be indicative of tropical enteropathy. This test was performed at enrollment and then 28 days later.

    Time frame: 28 days
