Years of potential life lost and valued years of potential life lost in assessing premature mortality in Slovenia.

Abstract

AIM: To determine the leading causes of death that contribute most to premature mortality in Slovenia; to classify premature mortality according to the cause of death, age, and sex; and to determine the age point before which premature mortality becomes a potential loss to the society. METHOD: Potential economic losses to society were estimated by use of years of potential life lost (YPLL), with a cut-off point at 65 years, and valued years of potential life lost (VYPLL) methods. We calculated the sex-, age-, and underlying causes of death-specific YPLL and VYPLL for residents of Slovenia who died at age younger than 65 years, using Slovene sex-specific life expectancy for 1998/1999 and age-specific weights of investment-producer-consumer model. RESULTS: In 1998, 4,558 YPLL per 100,000 population were lost to Slovenia. We found bimodal age distribution of YPLL, with the first peak in the 20-24 year age group and the second in the 45-49 year age group. Men to women rate ratio was 2.5. The leading causes of YPLL were external causes of death, followed by malignant neoplasms, and cardiovascular diseases. External causes, including suicides and traffic accidents, were the leading causes of death in men, whereas malignant neoplasms, including breast cancer and digestive cancer, were top-ranking causes in women. Among those, only external causes of death produced positive VYPLL, indicating a net loss to the society. CONCLUSION: In Slovenia, YPLL peaked in the 20-24 and 45-49 year age groups. Only external causes of death, most of which were preventable, accounted for the net economic loss to Slovenian society. We believe that YPLL and VYPLL, as specific mortality measures, can be reliably used in the evaluation of leading causes of death before age 65 and potential economic loss to the society caused by those deaths, and that they should be taken into account when setting public health priorities.
