Mortality statistics and death cause sequence of residents at sites of national surveillance in Chongqing in 2011

目的：了解重庆市居民病伤死亡原因监测点居民死亡水平和死因结构特点，为制定疾病控制策略提供科学依据。方法：综合全市8个疾病监测点的疾病监测资料，按照《国际疾病分类》第10版编码进行死因归类。计算粗死亡率、表化死亡率、死因构成比、死因顺位等指标，率的比较采用卡方检验。结果：监测点居民人群粗死亡率667．79／10万，标准化死亡率为473．39／10万，城市高于农村0（2=224．89，P〈0．001），男性高于女性（X2=572．44，P〈0．001）；65岁以上年龄组粗死亡率高于0-14岁、15～64岁瓴冬114118．60，P〈O．001）。居民死因顺位前5位为循环系统疾病（死亡率为249．01／10万，构成比为37．29％）、肿瘤（164．36／10万，24．61％）、呼吸系统疾病（131．27／10万，19．66％）、损伤中毒（53．78／10万，8．05％）和消化系统疾病（18．42／10万，2．76％）。结论：慢性非传染性疾病是重庆市疾病监测点居民生命健康的主要威胁，应协调社会各方力量，开展健康教育，改变不良生活行为，加强环境保护，积极控制慢性病的危害。

Objective：To understand the mortality and death cause sequence of residents from diseases surveillance sites in Chongqing so as to provide scientific references for formulating strategies of disease control. Methods ： Based on the data from 8 diseases survei- llance sites and international classification of diseases-lO,death causes were classified. Crude mortality,age-standardized mortality and proportion of death causes were calculated. Chi-square test was used to compare rates. Results：Crude mortality of residents from diseases surveillance sites was 667.79/100 000 and age-standardized mortality was 473.39/100 000. Crude mortality of urban was higher than that of rural（x2=224.89, P〈0.001 ）. Male＇s crude mortality was higher than female＇s （2=572.44, P〈0.001 ）. Crude mortality of aged more than 65 was higher than that of aged 0-14 and aged 15-64 （X2= 114 118.60, P〈0.001 ）. The top five death causes were circular system disease （crude mortality was 249.01/100 O00,proportion of death cause was 37.29%）, tumor（ 164.36/100 000, 24.61%）, respiratory system disease （ 131.27/100 000,19.66%）, injury and poisoning （53.78/100 000,8.05%） and digestive system disease（ 18.42/100 000,2.76%）. Conclusions ：Chronic non-communicable diseases are the diseases harming the residents in Chongqing. In order to actively control the harmfulness of chronic non-communicable diseases, all social parts should be mobilized to carry out health education, change the unhealthy life habits and strengthen environmental protection.
