The National Health Mission (NHM) primarily strengthens maternal and child health (MCH) services by allocating targeted funding and resources to improve healthcare infrastructure, outreach programs, and capacity building in both rural and urban areas. This support enhances immunization coverage, antenatal care, institutional deliveries, and nutrition programs, directly reducing maternal and child morbidity and mortality rates. NHM ensures accessibility and quality of essential MCH services through systematic financial and technical assistance to state and district health systems. Hence, its main contribution is in providing funding and support that enables comprehensive MCH interventions across the country.
