Pilot Study on a Locally Prepared Food Supplement to Support Growth and Brain Health

Malnutrition Clinical Trial

Official title: Pilot Study on a Locally Prepared Food Supplement to Support Growth and Brain Health

Status Completed

Clinical Trial Summary

This study is a randomized controlled pilot for a future larger trial. The goals of this pilot are: a) to assess feasibility of delivering a locally prepared supplement in rural communities, and b) to generate pilot data for sample size estimates needed for a larger trial. The study will test the effect of a supplement prepared locally with local and imported ingredients on changes in standard anthropometric benchmarks of growth, cognition, immune function, hemoglobin and skin carotenoids in young children living in 2 villages in rural Guinea-Bissau. Children in the active intervention village will be compared with assessment-only controls in a separate village having comparable demographic characteristics. As part of the study, we will assess the feasibility of having local commercial bakers prepare the supplement.

Clinical Trial Description

Up to 20 children aged 24-30 months and 20 school children aged 6-6.5 years living in each of 2 villages in the Oio region of Guinea-Bissau (total study population up to 80, with no minimum recruitment number) will be recruited for this study, with ages documented by the official birth record, which all families possess. Villages will be a convenience sample chosen from villages within the network of our local research partner International Partnership for Human Development. Each village in this region has one school and one community health center per village, which will be involved in supplement distribution and some outcome assessments. The villages will be broadly comparable in terms of size, affluence, rates of malnutrition, the presence or absence of a school meal program, and tribal affiliation and religion.

One village will be randomly assigned to receive the locally-prepared biscuit and a daily multivitamin and the other will be randomly assigned to be an assessment-only control site. Because this is a pilot study designed to develop methodology for a future powered trial, and the logistics of local supplement preparation need to be developed in advance of the study, the randomization will occur prior to baseline testing to allow for development of infrastructure for supplement preparation. However the villagers will not be informed of the randomization until after baseline testing is complete.

Following baseline measurements of anthropometry, grip strength, cognition, non-invasive measurements of hemoglobin, and skin carotenoids, participants will receive their intervention for 12 weeks and the same measurements taken at baseline will be repeated during the last study week. Since access for the final assessment to villages may be hampered by the rainy season we also request permission to terminate the trial between 9-12 weeks of supplement consumption depending on weather conditions. Please note that cell phone access to villages is not influenced by local weather, thus communication regarding safety issues with community health workers will remain possible throughout the entire trial. ;
