Significant progress has been made in maternal, newborn, and child health (MNCH) in recent decades. Between 1990 and 2015, the global mortality rate for children under age five years dropped by 53 percent, from 90.6 deaths per 1,000 live births in 1990 to 42.5 in 2015 (Liu and others 2016). Maternal mortality is also on the decline globally.1
Despite progress, maternal, neonatal, and under-five mortality remain high in many low- and middle-income countries (LMICs). In 2015, approximately 303,000 women died as a result of complications from pregnancy and childbirth (WHO 2015). Globally, an estimated 5.9 million children under age five years die each year, including 2.7 million within the first month of life (Liu and others 2016).
Health indicators differ across countries, regions, and socioeconomic levels (Lozano and others 2011). Approximately 99 percent of all newborn deaths occur in LMICs (Bayer 2001). Maternal mortality is concentrated in Sub-Saharan Africa (Hogan and others 2010), where mortality rates for the poor are double those for the nonpoor, and they are higher among rural populations and women with low levels of education (PLoS Medicine Editors 2010). Children living in low-income countries are three times more likely to die before age five years than children living in high-income countries (HICs) (Black and others 2013).
Pneumonia, diarrhea, malaria, and inadequate nutrition drive early childhood deaths around the world. In 2015, an estimated 526,000 episodes of diarrhea and 922,000 cases of pneumonia in children under age five years led to death (Liu and others 2016). Undernutrition is a primary underlying cause of 3.5 million maternal and child deaths each year (Black and others 2013); stunting, wasting, and micronutrient deficiencies are responsible for approximately 35 percent of the disease burden in children under age five years and 11 percent of the total global disease burden (Lozano and others 2011). Although maternal mortality is caused chiefly by postpartum hemorrhage, preeclampsia and eclampsia, and sepsis, a large proportion of maternal deaths can be attributed to limited access to skilled care during childbirth and the postnatal period (Lozano and others 2011) as well as to limited access to family planning services and safe abortions (UNFPA and Guttmacher Institute 2010).
An appropriate mix of interventions can significantly reduce the burden of maternal and child mortality and morbidity. However, these interventions often do not reach those who need them most (Bayer 2001; Sines, Tinker, and Ruben 2006). An integrated approach that includes community-based care as an essential component has the potential to substantially improve maternal, newborn, and child health outcomes.
This chapter provides a summary of community-based programs for improving MNCH. The chapter discusses strategies to improve the supply of services, including through community-based interventions and home visitations implemented by community health workers (CHWs), and strategies to increase demand for services, including through community mobilization efforts. The chapter summarizes the evidence about the impact of such interventions, describes contextual factors that affect implementation, and considers issues of cost-effectiveness. It concludes by highlighting research gaps, the challenges of scaling up, and the way forward.
