Causes of mortality in an African city

Registered deaths from the vital statistics registration system of Lagos City, a system that was judged to be 60% complete, were analysed for the year 1977. Nearly 40% of total registered deaths were from infections, parasitic diseases and motor vehicle accidents. Of the reported deaths, 17.3% were from ill-defined conditions. Deaths from neoplasms, diseases of the nervous and sense organs, diseases of the digestive and genitourinary systems as well as those from congenital anomalies are relatively less frequent. Maternal mortality appears to be very high. The age pattern of mortality is different from that in the developed countries, a high proportion of the deaths in Lagos City being those of children aged under 5 years. Infant mortality is dominated by perinatal causes which constituted a huge 38.4% of deaths of infants under 1 year, the other important causes being dysentery and diarrhoea, pneumonia and tetanus. Among adults, death from motor vehicles accidents is the most important cause accounting for more than 26% of deaths in the age group 15 years and above. Other important causes of adult deaths are cerebrovascular disease, hypertensive disease, heart disease, pneumonia, dysentery and diarrhoea and complications of pregnancy. Well organized health services stressing antenatal care, preventive and health education services are needed to effect a reduction in mortality and bring about a general improvement in the health of the people.
