The Maternal Mortality Ratio (MMR) is a crucial health indicator that reflects the number of maternal deaths per 100,000 live births, providing insight into the quality of healthcare and support for pregnant women and new mothers. Maternal deaths are defined as deaths occurring during pregnancy, childbirth, or within 42 days postpartum due to causes related to or aggravated by pregnancy or its management. MMR varies significantly across regions, influenced by socioeconomic factors, healthcare infrastructure, and access to essential medical services. The ratio remains high in low-income countries, as access to skilled healthcare, emergency obstetric care, and preventive measures, such as family planning and prenatal visits, may be limited. Conversely, countries with advanced healthcare systems generally see lower MMR, as timely and effective interventions are more accessible. Reducing MMR requires comprehensive strategies, including improved healthcare services, education, and socioeconomic support, to ensure the safety and well-being of mothers and infants worldwide.
