Results of two methods to determine health expectancy in The Netherlands in 1981-1985.

Health expectancy is a measure providing summarizing information on mortality on one hand and morbidity and/or disability on the other hand. In this article health expectancy is determined with two approaches: method 1 leads to life expectancy free of disability at birth and at other ages; method 2 leads to life expectancy in good health. Results of the various calculations show that according to method 1 life expectancy free of disability at birth for men in the Netherlands was 58.8 years and for women 57.3 years (based on data from the period 1981-1985). Results of method 2 are different from method 1; life expectancy in good health for men was 58.9 years and for women 60.7 years. Results of both methods are compared with studies which have been carried out in other countries. The comparison shows that method 1 leads to results which deviate from the other studies while results of method 2 are to a large extent similar to the other studies. Reasons are given which explain why the results of method 1 deviate from the other studies. In spite of the fact that the two methods lead to different outcomes, the conclusion is drawn that the difference in health expectancy between men and women is much smaller than the difference in total life expectancy between men and women. The difference in total life expectancy by sex in the period 1981-1985 was 6.7 years.
