Online published: 2014-09-02
Objective To analyze the mortality and variation trend of chronic obstructive pulmonary disease (COPD) in Ningbo from 2002 to 2012 and to provide evidences for prevention and control strategy of COPD. Methods The data of death surveillance for COPD in Ningbo from 2002 to 2012 was collected and analyzed by the death registry report software authorized by Ministry of Health of China and PASW 18.0 software. Results Standardized mortality rate of COPD of Ningbo residents declined from 82.35/100 thousand of 2002 to 52.21/100 thousand of 2012. The average decline rate was 4.5% per year. The trend of mortality rate of COPD was declining (χ2=1 191.401, P<0.01). The standardized mortality rate of males was 63.80/100 thousand, which was significantly higher than 59.73/100 thousand of females (χ2=22.952, P<0.01). The standardized mortality rate of rural areas was 86.99/100 thousand, which was significantly higher than 34.44/100 thousand of urban areas (χ2=1 079.716, P<0.01). The standardized mortality rate increased with the age (χ2=115 672.084, P<0.01). Conclusion COPD has become a serious public health problem. The death of COPD patients is relevant to various factors and comprehensive prevention and control measures need to be implemented.
