The assessment of the burden of disease (BOD) is necessary for sensibly allocating limited health-related resources. No such assessment is available currently for Italy.
Global burden of disease (GBD) methods were used to analyse in detail the years of life lost (YLLs) component of BOD for the most important diseases contributing to premature mortality in Italy in 1998. YLLs were computed with and without age-weighting and discounting. YLLs were also analysed by gender, for Italy vs. the Euro-A region (a group of 26 European countries) defined in the 2000 update of the GBD Study, and for northern, central and southern Italy, the three traditionally demarcated regions of the country.
The use of YLLs yields a ranking of diseases by their relative contribution to mortality burden which differs from a ranking based purely on death counts. Although males contributed 58.5% and females 41.5% of the total mortality burden in terms of YLLs, using death counts the percentages for males and females were similar (50.6% M, 49.4% F). The leading cause of mortality burden, both in terms of YLLs and death counts, was ischaemic heart disease, followed by stroke and lung cancer. Several other conditions, however, had rankings that varied depending on the measure used. While cardiovascular diseases accounted for 31.7% and 'all cancers' for 34.1% of YLLs, they were responsible, respectively, for 44.7 and 27.9% of death counts. The results for Italy generally corresponded with those obtained in GBD 2000 for EURO-A, but the proportion of the total mortality burden explained by the four leading causes is higher in Italy. For within Italy comparisons, there was a decreasing trend from north to south for 'all cancers' and for several specific cancers. Conversely, a consistent increase in YLL rates from north to south was observed for stroke and hypertensive disease.
This analysis of Italy's mortality burden represents the first phase in identifying Italy's total BOD. Simply establishing death counts and rates is no longer sufficient for a full understanding of a country's health status.
疾病负担评估对于合理分配有限的卫生相关资源十分必要。目前意大利尚无此类评估。
采用全球疾病负担(GBD)方法,详细分析了1998年意大利导致过早死亡的最重要疾病的疾病负担中寿命损失年(YLL)部分。计算了有无年龄加权和贴现情况下的YLL。还按性别、意大利与GBD研究2000年更新版中定义的欧洲A区(26个欧洲国家组成的一组)以及意大利传统划分的三个地区(北部、中部和南部)对YLL进行了分析。
使用YLL得出的疾病对死亡负担的相对贡献排名与单纯基于死亡人数的排名不同。就YLL而言,男性占总死亡负担的58.5%,女性占41.5%,而按死亡人数计算,男性和女性的百分比相似(男性50.6%,女性49.4%)。无论是按YLL还是按死亡人数计算,死亡负担的主要原因都是缺血性心脏病,其次是中风和肺癌。然而,其他一些疾病的排名因所采用的衡量方法而异。心血管疾病占YLL的31.7%,“所有癌症”占34.1%,但它们分别导致44.7%和27.9%的死亡人数。意大利的结果总体上与欧洲A区在GBD 2000中获得的结果一致,但意大利四大主要死因所解释的总死亡负担比例更高。在意大利内部比较时,“所有癌症”和几种特定癌症从北到南呈下降趋势。相反,中风和高血压疾病的YLL率从北到南呈持续上升趋势。
对意大利死亡负担的这一分析是确定意大利总疾病负担的第一阶段。仅确定死亡人数和死亡率已不足以全面了解一个国家的健康状况。
