Water and Sanitation

Mother and children at a well

Access to basic services, such as clean water and sanitation have important implications for children’s health and nutrition. Young Lives evidence on the impact of the quality of water and sanitation services on children’s health and nutrition suggests that:

  • Stunting throughout childhood is less common among those with access to good quality sanitation.
  • The quality of water and sanitation that households have access to determines the extent of catch-up growth during childhood.
  • Access to the highest available quality of sanitation among the poorest households has led to an increase of 0.3 standard deviations in the height-for-age z-scores of children belonging to these households.
