A study of multiple causes of death in California: 1955 and 1980.

Multiple cause of death patterns in California for 1980 were compared to a similar study of deaths conducted in 1955. Primary underlying causes of death changed, mainly reflecting the emergence of respiratory cancer as a major cause of death in 1980. The number of causes reported per death increased from 1955 to 1980, in all age and sex groups. Diseases of the arteries and pneumonia, which are among the most common underlying causes of death, appeared more often on death certificates in both 1955 and 1980 as contributing causes than as underlying the death. Diabetes was studied in detail in the 1955 report, and comparisons were made in 1980 to show increases in the proportions of deaths with this disease and corresponding increases in its prevalence among the living population from the National Health Survey. Multiple cause of death data can provide further information on the prevalence of a fatal disease in a population and its relative role in contributing to mortality, and can also provide new information on diseases that contribute to deaths, which was not previously available in population-based studies of single cause of death.

Childhood injury deaths: national analysis and geographic variations.

Twenty-three causes of injury mortality in children ages 0-14 in the United States were analyzed by age, race, sex, and state of residence for the years 1980-85. Motor vehicles caused 37 per cent of all injury-related deaths and were the leading cause of injury mortality in every group except children younger than one year, for whom homicide was the leading cause. Male death rates were at least four times female rates for suicide, unintentional firearm injury, and injuries related to farm machinery or motorcycles. The drowning rate among Whites was almost twice that of Blacks for ages 1-4, but in the 10-14 year age group the drowning rate for Blacks was over three times that of Whites. In general, the highest injury death rates were in the mountain states and the south. Between 1980 and 1985, the suicide rate in the 10-14 year age group more than doubled.
