Asthma mortality in Israel 1971-1990.
BACKGROUND
One of the enigmas in asthma is that our improved understanding of the pathophysiology and the introduction of new modalities to treat asthma has not led to a parallel decrease in asthma mortality. On the contrary, morbidity and mortality from asthma have increased since the mid-seventies in most of the western countries. This trend of increased asthma mortality rate was not observed in Israel in a survey that examined the changes in asthma mortality rate in Israel during 1960-1986. A small but statistically insignificant increase in asthma mortality rate during the last years of that survey solicited for reexamination and extension of the survey.


OBJECTIVE
The purpose of the present study was to evaluate the changes in the asthma mortality rate in Israel during the years 1971-1990.


METHODS
We extracted the statistical data on asthma mortality rate in Israel during the 1971-1990 period. Because of the small numbers each year and the variations in asthma mortality rate between years, the data were analyzed after grouping the asthma mortality rate into 5-year periods.


RESULTS
The rates, expressed as deaths per 100,000 population per year, were 0.43, 0.18, 0.39, and 0.40 in the 5- to 34-year-old group for the periods 1971-1975. 1976-1980, 1981-1985, and 1986-1990, respectively. We found a statistically significant increase in asthma mortality rate during the 1981-1985 and 1986-1990 periods as compared with 1975-1980 in the young (<34 years old) population. The increase in asthma mortality rate was greater among males. The mortality rate in the older population (35-64 year olds) decreased during 1976-80 as compared with 1971-1975 but did not change thereafter. The rates were 10.4, 4.8, 4.5, and 4.4 cases per 100,000 for 1971-1975, 1976-80, 1981-85, and 1986-90, respectively.


CONCLUSIONS
Asthma mortality rate increased in Israel in the young age group (5-34 years) during 1980-1990. This is similar to reports from many other countries with advanced medical care systems. The decrease of asthma mortality rate in 1976-80 probably reflect the general improvement in medical care in Israel during these years.
