By combining a set of cross-sectional age specific prevalence with a period life table (which corresponds to a real projection of the survival function in the future if the mortality rates remain constant over time), the Sullivan method is hybrid and is only a first method to understand the concept of Health Expectancy, even if it is, most of time, the only index which can be computed.
You can download a spreadsheet (Excel) sulliv2.xls which will help you to compute a Sullivan index from a period life table and prevalence rates estimates from a disability survey. The computation of the standard deviation of the index due to a small sample is also included. It will correspond to a forthcoming version of a Practical Guide.
An earlier version of this Practical
Guide, written by Eric Hauet, has also a spreadsheet,
.
sulliv1.xls.
It takes the example of France in
1981 and 1991 for females, including the information brought by the
1990 census on the institutionalized population, because the french
Health surveys did not sampled institutions.
