Official title
A Randomized, Double Blind, Controlled Study to Determine the Efficacy of Zinc Supplementation on Diarrhea Incidence in an Adult Population in Western Kenya.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Zinc deficiency is prevalent in children in developing countries. Zinc-supplementation is proven to reduce the duration and severity of childhood diarrhea in randomized controlled trials. However, despite this evidence, its efficacy to reduce diarrhea morbidity in adults remains unknown. The main objective of this study is to determine the efficacy of Zn-supplementation on diarrhea incidences in a vulnerable adult population. The study will be carried out in Kombewa division, Kisumu District and will involve 500 adults aged 18-55 years. They will be randomly assigned to receive Zn supplement (or placebo) on a daily basis over a 3 month period. Morbidity information will be collected daily for 4 months, while anthropometric measures and laboratory data will be obtained at study onset, end of supplementation and study conclusion. In addition, HIV and malaria tests will be carried out during the study as they are important confounders. The significant differences in diarrhea incidence between the Zn-group and the placebo-group will be determined using SPSS. The results are expected to provide the scientific basis and common pathway for development of an anti-diarrheal supplement for vulnerable populations such as environmental refugees, deprived and displaced persons, and troops prior to deployment.
