[Incidence of sudden cardiac death of urban residents in Beijing].

OBJECTIVE: To explore the incidence of sudden cardiac death (SCD) of urban residents in Beijing. METHODS: A community based epidemiology survey was performed on the residents of 4 communities in the Xicheng and Haidian districts in Beijing from October 2008 to September 2009. Data on the total population, age, gender and vital status were monitored, and incidence of SCD as well as related information were collected from the household administrative workers, the family members of the deceased, the hospital personnel and the witnesses. RESULTS: 479 521 subjects (244 000 men and 235 521 women) were monitored, a total of 1 285 (642 men and 643 women) all cause death occurred during the study period and 184 (86 men and 98 women) deaths were identified as SCD. The incidence of SCD was 35.2 (95%CI 27.8-42.7) per 100 000 per year for men and 41.6 (95%CI 33.4-49.8) per 100 000 per year for women. SCD accounted for 13.4% mortality in men and 15.2% mortality in women. There were 171 (91.0%) SCD cases in residents over 55 years of age. The incidence of SCD for the age group 0-24, 25-34, 35-44, 45-54, 55-64, 65-74 and 75 years and over was 5.6, 4.6, 3.0, 9.8, 78.4, 88.4, and 272.8 per 100 000 per year for men, and 1.6, 0, 3.2, 0, 21.1, 84.2 and 470.0 per 100 000 per year for women, respectively. The proportion of the cases that have at least one cardiovascular disease history was 57.0% (49/86) for men and 60.2% (59/98) for women. The cases that occurred at home, on the way to hospital, in the hospital emergency room, in the hospital ward and other places account for 53.3% (98 cases), 12.2% (22 cases), 9.2% (17 cases), 12.5% (23 cases) and 13.0% (24 cases) of the 184 SCD cases, respectively. CONCLUSION: SCD is a great threat to the urban residents in Beijing. Most SCD cases occurred at home on residents over 55 years of age. More than half SCD residents have at least one cardiovascular disease. It is important to take preventive measures in the urban residents over 55 years old and with history of cardiovascular disease.

Death and life loss of malignant tumors in Xicheng District from 2014 to 2021 / 预防医学

Objective@#To investigate the mortality and life loss of malignant tumors among residents in Xicheng District, Beijing from 2014 to 2021, so as to provide the evidence for formulating the control strategy for malignant tumors.@*Methods@#Data pertaining to dead cases of malignant tumors in Xicheng District from 2014 to 2021 were collected from Beijing Integrated and Analysis Platform for Health and Disease Prevention Monitoring Information Resources. The crude mortality, standardized mortality, years of potential life lost (YPLL), years of potential life lost rate (YPLLR), rate of standardized years of potential life lost (SYPLLR), average years of life lost (AYLL) and annual percent change (APC) of malignant tumors were measured to analyze the trends in mortality of malignant tumors and life loss.@*Results@#A total of 23 202 residents died from malignant tumors in Xicheng District from 2014 to 2021, and the crude and standardized mortality rates of malignant tumors were 198.09/105 and 101.46/105, respectively. The standardized mortality of malignant tumors was 117.36/105 among men and 85.97/105 among women. The standard mortality of malignant tumors appeared a tendency towards a decline among all cases (APC=-1.515%, t=-4.289, P=0.005) and women (APC=-1.629%, t=-3.046, P=0.023), and the crude mortality of malignant tumors appeared a tendency towards a rise with age (χ2trend=49.324, P<0.001). The five most deadly malignant tumors included lung cancer, colorectal cancer, liver cancer, stomach cancer and pancreatic cancer, and lung cancer, liver cancer and colorectal cancer were the three malignant tumors with the three highest life loss, with YPLL of 18 054 person-years, 9 446 person-years and 8 179 person-years, respectively. Leukemia had the highest AYLL (15.95 years per person).@*Conclusions@#The standardized mortality of malignant tumors appeared a tendency towards a decline among residents in Xicheng District from 2014 to 2021, and men and the elderly people were at high risk of malignant tumors. Lung cancer, colorectal cancer and liver cancer were leading causes of death, leukemia was the major cause of life loss.
