This study aimed to analyze the impact of changes in age-related and cause-related mortality on life expectancy at birth in the State of Santa Catarina, Brazil, in the 1990s. Data were obtained from the Mortality Information System (SIM) for the three-year periods 1989/1990/1991 and 1998/1999/2000. Infant mortality rates and specific mortality rates for individuals > or = 1 year of age were calculated by gender and cause of death. The Pollard method was used to disaggregate the contributions by mortality from different causes and in different ages to life expectancy at birth. The age groups that contributed the most to the increase in life expectancy at birth were 0-1 year and > or = 70 years. The causes of death that most contributed to this increase were chronic non-communicable diseases, such as cardiovascular diseases, in the age brackets above 35 years, and neonatal diseases in the < 1-year bracket. Finally, there were a high proportion of deaths from ill-defined causes, indicating that the true cause-related mortality structure in the State is still unknown.
本研究旨在分析20世纪90年代巴西圣卡塔琳娜州年龄相关和病因相关死亡率变化对出生时预期寿命的影响。数据来自1989/1990/1991年和1998/1999/2000年这两个三年期的死亡信息系统（SIM）。按性别和死因计算了1岁及以上人群的婴儿死亡率和特定死亡率。采用波拉德方法分解不同病因和不同年龄的死亡率对出生时预期寿命的贡献。对出生时预期寿命增加贡献最大的年龄组是0至1岁和70岁及以上。导致这一增长的主要死因是35岁以上年龄组的慢性非传染性疾病，如心血管疾病，以及1岁以下年龄组的新生儿疾病。最后，死因不明的死亡比例很高，这表明该州真正的病因相关死亡率结构仍不明确。
