Vitamin A and Zinc: Prevention of Pneumonia (VAZPOP) Study

This study has been completed.

Sponsors and Collaborators: Tufts University
Corporacion Ecuatoriana de Biotecnologia
Information provided by: Tufts University
ClinicalTrials.gov Identifier: NCT00228254
  Purpose

Children with malnutrition are often low in some nutrients, like zinc or vitamin A, that could help them fight off infections like pneumonia. Our study was designed to see if children who got supplements of zinc or vitamin A had fewer infections.


Condition Intervention Phase
Pneumonia
Diarrhea
Acute Upper Respiratory Tract Infections
Drug: Zinc (12.5 mg/day)
Drug: vitamin A 10,000 IU per week

Primary Outcome Measures:
  • Incidence of acute lower respiratory infection (pneumonia)
  • Growth

Secondary Outcome Measures:
  • Additive or synergistic effects of zinc and vitamin A
  • Incidence of diarrheal disease
  • Incidence of other respiratory infections

Detailed Description:

The Vitamin A and Zinc: Prevention of Pneumonia (VAZPOP) study was a multi-year nutritionally-stratified, placebo-controlled, double-blind study of low-dose vitamin A and/or zinc in 2,582 normal and malnourished urban children aged 6 to 36 months in Quito, Ecuador. Four group of ~ 645 children were enrolled in 2000, 2001, 2002, and 2003 with each child participating for up to 50 weeks. Children were visited 4 days each week. Outcome measures were pneumonia, other respiratory tract infections, diarrheal disease, and growth.
