Abstract

The objectives of this study were to produce reliable matenal mortalify indices and to define the causes of maternal death through a national survey of the total population. The study subjects were all maternal deaths that occurred from January 1, 1995 to December 31, 1996.
The sources of data were the medical fee claims for pregnancy and delivery, the claims for funerals of woman of reproductive age(15∼49 years) submitted to medical insurance corporations, the birth and death registrations, of the National Statistical Office, the medical records of women of reproductive age who died in the above mentioned period at a health facility, and the resident registration record. Data from these four sources were linked together to create one data file from which maternal deaths were identified.
The definition of maternal death in this study was the same as defined by WHO, i.e., the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management, but not from accidental or incidental causes.
The number of maternal deaths was 146 in 1995 and 142 in 1996. The maternal mortality ration per 100,000 live births was 20 in both 1995 and 1996. The age-specific maternal mortality ratio curve was J-shaped ; the age group of 19 years or younger showed a high ratio of 46, the lowest ratio was for the age group 20∼24 years of age(11), and the there was a sharp increase with age thereafter(14 for ages 25∼29, 26 for ages 30∼34, 79 for ages 35∼39, and 223 for ages 40 and over). The maternal mortality rate(the number of maternal deaths per 1,000 females 15∼49 years old) was 0.011 in both 1995 and 1996. The proportion maternal(percent of maternal deaths among adult female deaths) was 1.2% in both 1995 and 1996. The lifetime risk of maternal deaths, which reflects the chances of a woman dying from maternal causes over their 35 year reproductive life span, was one in 2,408 women in 1995 and one in 2,399 women in 1996.
