ABSTRACT
Objective To analyze the status and trend for the mortality and DALY rates of child growth failure (CGF) in children aged < 5 years in China from 1990 to 2019, so as to provide a scientific basis for CGF prevention and control. Methods The mortality and DALY rates of CGF in children aged < 5 years from 1990 to 2019 were obtained from GBD 2019. The changes of these indicators with the years in China , the United States, Japan, Russia, India and the global were compared and analyzed. Results In 2019, the mortality of child wasting, child stunting and child underweight in children aged < 5 years in China were 9.62/100 000, 1.23/100 000, and 1.29/100 000 respectively, the mortality rates were 867.50/100 000 , 129.23/100 000 , and 112.87/100 000 rescpectively, higher than those of the United States, Japan, and Russia, and far lower than those of India and the global. The disease burden of three types of CGF were all higher in males than females, and higher in children aged < 1 years than children aged 1-4 years. From 1990 to 2019, the mortality and DALY rates of CGF in children aged < 5 years in China decreased from 300.41/100 000 and 26 445.38/100 000 to 10.49/100 000 and 943.57/100 000, respectively. China had the largest drop rate compared with all analyzed countries. As for children aged < 5 years in China, the DALY rate of lower respiratory infection ranked first in all the diseases caused by CGF. Conclusion From 1990 to 2019, the disease burden of CGF in children aged < 5 years has shown a significant decrease in China , but it is still far behind the developed countries. In the future, more attention should be paid to the problems of child growth in hope of reducing the mortality and DALY rates of CGF.
ABSTRACT
@#Objective To analyze the status and trends for the prevalence，morbidity，mortality， and DALY of tuberculosis ( TB) in China from 1990 to 2017，so as to provide scientific basis for TB pre- vention and control． Methods From 1990 to 2017 in China，the United States，India，Japan，and the global，the TB ( standardized) prevalence，( standardized) morbidity，( standardized) mortality，and ( standardized) DALY rates were obtained from Institute for Health Metrics and Evaluation ( IHME) web- site，and comparative analysis of changes in these indicators with years were carried out． Ｒesults In 2017， the prevalence，morbidity，mortality，and DALY rate of TB in China were higher in the high-age group than in the low-age group． The prevalence，morbidity，mortality，and DALY rates were all higher for males than females． The prevalence was 29 641. 59/100 000 and 28 803. 26/100 000 for male and female，respectively． The male and female mortality rates were 72. 23/100 000 and 44. 85/100 000． The male and female mortali- ty rates were 3. 85/100 000 and 1. 67/100 000，and the DALY rate of male and female were 156. 95/100 000 and 84. 73/100 000． From 1990 to 2017，the prevalence of TB decreased from 32 178. 39/100 000 in 1990 to 29 231. 80/100 000 in 2017，the morbidity rate of TB decreased from 141. 83/100 000 in 1990 to 58. 83/100 000 in 2017，the mortality rate of TB decreased from 13. 82/100 000 in1990 to 2. 78/100 000 in 2017，and the DALY rate of TB decreased from 582. 87/100 000 in 1990 to 121. 60/100 000 in 2017． Conclusions The burden of TB in China declined markedly from 1990 to 2017． Although some progress has been made in the prevention and treatment of TB in China，but there is still a certain gap compared with de- veloped countries． It is still necessary to further reduce the morbidity rate and mortality rate of TB．
ABSTRACT
<p><b>OBJECTIVE</b>To assess the data quality and estimate the provincial infant mortality rate (1q0) from China's sixth census.</p><p><b>METHODS</b>A log-quadratic model is applied to under-fifteen data. We analyze and compare the average relative errors (AREs) for 1q0 between the estimated and reported values using the leave-one-out cross-validation method.</p><p><b>RESULTS</b>For the sixth census, the AREs are more than 100% for almost all provinces. The estimated average 1q0 level for 31 provinces is 12.3‰ for males and 10.7‰ for females.</p><p><b>CONCLUSION</b>The data for the provincial 1q0 from China's sixth census have a serious data quality problem. The actual levels of 1q0 for each province are significantly higher than the reported values.</p>
