Women in Ghana suffer from one of the highest perinatal mortality rates in the world. Every day in Ghana, 47 babies are stillborn and 232 babies are born with LBW - many of whom will die in infancy or suffer lifelong consequences. As such, Ghana urgently requires inexpensive interventions to reduce perinatal morbidity and mortality - assisting pregnant Ghanaian women to avoid sleeping on their back might be one such intervention.
