The Meals, Education, and Gardens for In-School Adolescents (MEGA) Project aims to implement and evaluate a comprehensive, school-based nutrition intervention package among secondary schools in Dodoma, Tanzania. The intervention will include four primary components: (1) school garden, (2) school meal program, (3) agriculture, nutrition, and water, sanitation, and hygiene (WASH) education, and (4) community workshops.~This will be a cluster randomized trial with 3 arms, containing two schools each. At the beginning of the academic year, six schools will be randomized to intervention or control. Two schools will receive the full intervention package (school lunch, school garden, and education), two schools will receive the partial intervention package (school garden and education), and two schools will serve as control to receive the standard of care. Community workshops will also be provided to parents of adolescents in full and partial intervention schools.~In the full intervention schools, all adolescents will receive a midday meal, while a subset of Forms 1 or 2 adolescents will additionally participate in a school gardening program that includes nutrition, agriculture, and water, sanitation, and hygiene (WASH) education, led by selected teachers. Parents of adolescents in full intervention schools will be invited to participate in community workshops on nutrition, hygiene, and agricultural best practices, led by community Agriculture Extension Workers (AEWs).~In the partial intervention schools, Forms 1 or 2 adolescents will participate in the gardening and education components described above, but will not receive the midday meal. Parents of participating adolescents will also be invited to participate in the community workshops.~Adolescents in control schools will not receive any of these interventions but will be provided with standard of care practices at secondary schools in Dodoma. In addition, teachers in control schools will receive a hard copy of educational materials on nutrition, agriculture, and WASH to enhance their lesson plans. The intervention will take place over the course of one year.~The goal of the MEGA project is to study the effects of the integrated intervention on the nutrition and health of adolescents and their families in Tanzania. Ultimately, we aim to use the findings from this study to inform the scale-up of future school and community-based interventions to improve nutrition through training, improved crop production, and increased consumption of vegetables.
This purpose of this study is to assess effects of a comprehensive, school-based nutrition intervention package on anemia status, anthropometric indicators, school performance/attendance, and development indicators among adolescents, and the knowledge, attitudes, and practices of nutrition, agriculture, and WASH among parents, in Tanzania.
