A theory-based behavioural change communication intervention to decrease the provision of water to infants under 6 months of age in the Republic of Guinea.

Objective: In many countries, the provision of water in the early months of a baby's life jeopardises exclusive breast-feeding (EBF). Using a behavioural theory, this study assessed the impact of a behaviour change intervention on mothers' intention to act and, in turn, on the water provision in addition to breast milk to their infants under 6 months of age (IU6M) in two regions of Guinea.

Design: A quasi-experimental design.

A tool to assess underlying factors to water provision among Guinean children.

In many countries, water is provided to children under 6 months of age (CU6M) in addition to breast milk (BM), hence increasing the risk of child mortality and morbidity. Factors related to this practice have not been thoroughly investigated either a tool to assess them. Based on the extended theory of planned behaviour (eTPB), we aim to develop and validate a questionnaire to assess psychosocial and environmental factors that may contribute/limit the water provision in addition to BM by mothers of CU6M in the Republic of Guinea.
