邳州市1990—1999年居民意外伤害死亡原因及趋势分析

目的为探讨邳州市居民意外死亡的水平、原因、分布特征及变动趋势.方法采用2×C表线性回归的显著性检验原理结合流行病学方法,对本地区1990～1999年意外死亡者分布特点,死亡率、减寿率作趋势分析.结果10年间意外伤害死亡率平均为84.81/10万,在全死因中次于呼吸系病、恶性肿瘤、循环系疾病居第4位,而在潜在寿命损失(YPLL)居首位.意外伤害死亡率呈下降趋势(P＜0.01),但标化死亡率(84.96/10万)仍高于全国(65.24/10万)和全国农村(72.10/10万)人群的水平,YPLL下降也有极显著意义,但幅度和速度均超过死亡率下降水平.结论提示意外死亡是当前影响居民健康的重要原因.但对寿命影响程度减少.

Analysis on the Accidental Injury Death in PiZhou City during 1990-1999

Objective To study the accidental death level,cause,distributional,characteristic and tendency,and provide scientific basis for prevention and controlment.Methods Siglificance test of linear regression in 2*C table and epidemiology method were used to study the trend of the mortality and YPLL rate.Results The mortality rate of accidental injury in ten years was 84 81/10 5,lower than respiratory disease,cancer and circulation system disease,ranked the fourth among all death causes.While the YPLL of accidental injury was the first rank.The mortality rate of accidental injury death rate was on the decrease(p<0 01).The SMR(84 96/10 5)was higher than the whole country(65 24/10 5)and the whole countryside(72 10/10 5).YPLL rate declined remarkedly(P<0 01).Both its range and speed exceeded the level of the mortality declined.Conclusion The death caused by accidental injury was the key cause that affected people's health,but it had smaller effect on life lost.
