Background and study aims
It is estimated that that 20 million low-birth-weight babies are born each year, 314 million children under 5 years of age experience mild to severe stunting, and over 200 million children are not meeting their developmental and cognitive potential. Reducing the number of Tanzanian children facing these early life adversities is vital given the large negative long-term consequences of early developmental delays in terms of individual earnings and social capital. Children experiencing in utero or early childhood adversity generally enrol later in school (if they enrol at all), perform poorly on academic tests, complete less education than their peers, and have reduced personal income later in life. Accordingly, improving early life environments will likely not only improve child growth and development in the short run, but also contribute to more educated and productive future societies. The aim of this study is to assess a child growth and development intervention package delivered by community health workers (CHWs) in Morogoro Region, Tanzania. The study also looks at whether conditional cash transfers for antenatal care and well-child clinic visits improve child growth and development.
Who can participate?
Pregnant women and mothers/caregivers of infants under 1 year of age
What does the study involve?
Participating villages are randomly allocated to one of three groups. In the first group CHWs deliver the intervention package once a month in the home. In the second group CHWs deliver the intervention package once a month in the home and also conditional cash transfers to promote antenatal care and child growth monitoring clinic visits. The third group receive standard care. Participants receive the interventions for a duration of 18 months. The total duration of follow-up is 18 months. Child development and height are assessed at 9 and 18 months.
What are the possible benefits and risks of participating?
The benefit of participating is that children may receive health and development benefits from the intervention. There are no expected risks associated with participation.
Where is the study run from?
Ifakara Health Institute (Tanzania)

Scientific title | Effectiveness of approaches to deliver integrated solutions for optimal child growth and development in Tanzania |
Study objectives | 1. Community health worker (CHW) delivery of evidence-based nutrition and responsive stimulation intervention package improves child growth and development. 2. Cash transfers conditioned on antenatal care and well-child clinic visits improve child growth and development. |

Health condition(s) or problem(s) studied | Child growth and development |
Intervention | This study is a pilot cluster-randomized trial to evaluate integrated supply and demand sided platforms to deliver a child growth and development intervention package in Morogoro Region, Tanzania. 12 villages will be randomized within strata of peri-urban (6 villages) and rural (6 villages) to one of three study arms: 1. CHWs Only: CHWs deliver a nutrition and responsive stimulation caregiver intervention package once a month in the home 2. CHWs + CCT: CHWs deliver a nutrition and responsive stimulation caregiver intervention package once a month in the home plus conditional cash transfers to promote ANC and child growth monitoring clinic visits 3. Control: Participants will receive standard of care Villages receive the randomized treatment for a duration of 18 months. The total duration of follow-up is 18 months. |
Intervention type | Behavioural |
Primary outcome measure | 1. Child development measured by the Bayley Scale of Child Development, 3rd edition at 9 and 18 months 2. Child height-for-age z-score assessed at 9 and 18 months |
Secondary outcome measures | 1. Attendance to ANC and child health visits assessed by health cards at 9 and 18 months 2. Caregiver parenting knowledge assessed by the Caregiver Knowledge of Child Development Inventory at 9 and 18 months 3. Child weight-for-height z-score assessed at 9 and 18 months 4. Child weight-for-age z-score assessed at 9 and 18 months |
