ABSTRACT
@#Objective To understand the overall under-reporting of cause of death monitoring in Hainan Province, and to provide a scientific basis for evaluating the data from death registration report and health planning in Hainan. Methods Multi-stage cluster random sampling was used, all towns/streets in cities and counties of the province were ranked from highest to lowest in terms of crude death rate, divided into high, medium and low levels (the number of each level was basically the same), and one was randomly selected from each level. A total of three towns/streets were used as survey areas, and all households in the area were survey households. Death information of resident population during 2018-2020 was collected and compared with routine surveillance data for the same period. The under-reporting rate was calculated, and comparison between groups was performed by chi-square. Results A total of 12 583 death cases were investigated from 2018 to 2020, and the average mortality was 621.48/105. 4 809 cases were missed with the total under-reporting rate of 38.22%. The under-reporting rate from 2018 to 2020 were 39.75%, 39.99% and 34.77% (χ2=30.404, P<0.01) respectively. The under-reporting rate in eastern and central and western areas were 30.33%, 30.10% and 60.15% (χ2=931.901, P<0.01) respectively. The negative rate were different in different years old group (χ2=14.834, P<0.05). Of the 4 809 under-reported cases, as many as 93.49% died at home, and the composition of deaths in hospitals was about 10 times higher in the center than in the east and west, and the proportion of those who died in hospital in central areas was about 10 times higher than in eastern and central areas. Conclusions More than half of the cities and counties in Hainan Province have improved the completeness of cause of death surveillance data. The under-reporting rate in age group <5 years are still high, and regular under-reporting investigations are still needed to strengthen the reporting and management of death information.
ABSTRACT
Objective To analyze the trends on mortalities of all-cause and deaths caused by chronic and non-communicable diseases (NCDs) among Chinese labor force population during 2007 to 2016.Methods Data on cause-of-death that collected from the National Mortality Surveillance System was used to analyze the age and area-related specific crude mortality rates,age-standardized mortality rates and component ratios of NCDs,among the Chinese labor force population,during 2007 to 2016.Trend of crude mortality rates and mortality component ratios of the three major diseases (infectious diseases,maternal and infant diseases,nutritional deficiency diseases;NCDs;injuries) were analyzed.Age-standardized mortality of cancer,COPD,cardiovascular and cerebrovascular diseases were also analyzed by gender.Age-standardized mortality was calculated based on the Year 2010 Population Census of China.Joinpoint regression model was used to obtain annual percentage change and 95％CI was set for assessing the trend.Results In 2016,the age-standardized all-cause mortality rate was 217.23 per 100 000 among the Chinese labor force population,but decreased by-2.8％ (95％CI:-3.8％--1.7％) annually from 2007 to 2016.The gap between different gender and regions gradually narrowed.The proportion of deaths caused by NCDs increased annually by 0.8％ (95％CI:0.7％-0.9％).The age-standardized mortality rate of NCDs appeared as 171.89/100 000,among the Chinese labor force population in 2016,showing a downward trend by-2.4％ (95％CI:-3.3％--1.4％).However,in females,there appeared the greatest decrease,with an average annual change of-3.3％ (95％CI:-4.0％--2.5％).Diseases as cancer,COPD,cardiovascular and cerebrovascular diseases all showed downward trends in the whole country,with an average range of-2.0％ (95％CI:-2.6％--1.3％),-8.0％ (95％CI:-8.9％--7.1％),-1.5％ (95％CI:-2.9％--0.1％),-2.3％ (95％CI:-2.8％--1.8％)in a ten-year period,respectively.Conclusion All-cause and age-standardized mortality rates caused by NCDs among Chinese labor force population were decreasing during 2007 to 2016.However,the constituent ratios appeared increasing,year by year.Close attention needs to be paid on NCDs which affecting the health of the labor force population in China.

ABSTRACT
Objective To evaluate the under-registration rate related to mortality surveillance program in Jinan city,from 2013 to 2014,using the capture-mark-recapture method.Methods Under the stratified cluster random sampling method,samples were stratified,according to urban and rural areas.Two districts and three counties were chosen,with three towns/streets in each county/district and eight villages/communities in each township/street,randomly selected.With the participation of departments as civil affairs,public security,maternal/child institutions and community committees as well as individuals as village doctors and community leaders,a list of deaths from January 1,2013 to December 31,2014 was collected and compared to the National Mortality Surveillance System on the rates related to under-registration.Results A total of 2 903 records on deaths were collected from 2013 to 2014,while 3 113 deaths were reported in the surveillance system of the same period.3 772 (95％ CI:3 741-3 802) deaths were estimated by the capture-mark-recapture method.The two-year total under-registration rate was 17.46％.The under-registration rates in 2013 and 2014 appeared as 19.29％ and 15.57％ (x2 =8.92,P＜0.01),respectively,with the rates in urban and rural areas as 20.91％ and 11.93％ (x2 =47.35,P＜0.01).The rates on male and female were 17.87％ and 16.98％ (x2 =0.48,P＞0.05).The rates of ＜5 years old group and ≥5 years old group were 21.57％ and 17.45％ (x2 =0.03,P＞0.05) respectively.Conclusions Under-registration in the mortality surveillance was noticed in Jinan.The capture-mark-recapture method seemed useful for evaluating the under-registration rate in the mortality surveillance program.It is suggested that the survey on under-registration rate should be carried out on the regular base.The under-registration rate seemed useful in adjusting the mortality rate.
