Incidence and Mortality of Eye Cancer in Shandong, China: A Population-based Study During 2013-2017

Abstract Background: Eye cancer is relatively rare. Current prevalence and disease burden of eye cancer are unlcear.The purpose of this study was to understand the epidemiology in the incidence and mortality of eye cancer in Shandong Province, and to provide reference for the prevention and control of eye cancer.Methods: Population-based cancer incidence and death data from cancer registries in 2013-2017 was collected by Shandong Center for Disease Control and Prevention (SDCDC). Extracted data were firstly assessed for data quality and then were aggregated by area (urban/rural), gender, and age group [0, 1-4, 5-9, 10-14, …, 85+]. Crude and age-adjusted incidence and mortality rates were calculated.Results: The reported numbers of eye cancer incident cases and deaths in Shandong cancer registry from 2013 to 2017 were 169 and 43, respectively. The crude incidence rate, age-standardized rate of incidence by Chinese population (ASRIC, 2000) and world population (ASRIW) were 11.12/107, 8.92/107 and 12.44/107, respectively. The crude mortality rate, age-standardized rate of mortality by Chinese population (ASRMC, 2000) and world population (ASRMW) were 2.83/107, 1.89/107 and 2.58/107, respectively. There were no marked differences in the incidence and mortality rates between male and female. The incidence rates were similar between rural and urban areas. The mortality rate in rural areas was higher than that in urban areas. The mortality-to-incidence (M/I) ratio in rural areas (0.30) was considerably higher than that in urban areas (0.18). The highest incidence was observed in children aged 0-4 years old, which was true for both urban and rural areas, and for both genders,Conclusion: Eye cancer is not a common malignant tumor in this population. Prevention and control measures should be tailored according to the epidemiological characteristics and risk factors of eye cancer.

Population Based Survey

Background: In China, stroke is the leading cause of death and contributes to a heavy disease burden. However, a nationwide population-based survey of the mortality of stroke and its subtypes is lacking for this country. Methods: Data derived from the National Epidemiological Survey of Stroke in China, which was a multistage, stratified clustering sampling-designed, cross-sectional survey, were analyzed. Mortality rate analyses were performed for 476,156 participants ≥20 years old from September 1, 2012 to August 31, 2013. Results: Of the 476,156 participants in the investigated population, 364 died of ischemic stroke, 373 of hemorrhagic stroke, and 21 of stroke of undetermined pathological type. The age-standardized mortality rates per 100,000 person-years among those aged ≥20 years were 114.8 for total stroke, 56.5 for ischemic stroke, and 55.8 for hemorrhagic stroke. The age-standardized mortality rates of total stroke, ischemic stroke, and hemorrhagic stroke were all higher in rural areas than those in urban areas. The stroke mortality rate was higher in the northern regions than in the south. An estimated 1.12 million people aged ≥20 years in China died of stroke during the period from September 1, 2012 to August 31, 2013. Conclusions: The burden of stroke in China is still heavy. Greater attention should be paid to improve strategies for preventing stroke.

Joinpoint Regression Analysis

PurposeDiabetes mellitus is emerging as an epidemic worldwide, and the incidence and prevalence of diabetes have drastically changed in China over the past 30 years, but data on its mortality rate are scarce. This study aimed to analyze the time trends of mortality rates among patients with diabetes in the rural and urban population in China between 1987 and 2019.MethodsThe research data come from China’s annual report on national health statistics and the Chinese Health Statistics Yearbook. Age-standardized mortality rates were calculated by using the direct method based on the World Standard Population from the WHO. Joinpoint regression analysis was employed to estimate the annual percent change and average annual percentage changes of mortality rates of diabetes mellitus.ResultsAn overall trend for increment in diabetes mortality was observed. The crude mortality rates and age-standardized mortality rates of diabetes for urban and rural residents in China showed a significant increasing trend between 1987 and 2019. Mortality due to diabetes in urban areas has been higher than in rural areas for 30 years. However, due to the rapid increase of rural diabetes mortality in the past decade, the gap between the two gradually narrowed. The age-standardized mortality rates of diabetes increased by about 38.5% in urban areas and 254.9% in rural areas over the whole study period. In addition, the age-standardized mortality rate of females with diabetes was higher than that of males, but this pattern began to change in urban areas in 2012. Finally, the age-standardized mortality rates in the elderly population in China are higher with a faster growth rate, especially in rural areas.ConclusionThe mortality rate of diabetes is on the rise in China. The rapid growth of the mortality rate of diabetes in rural areas leads to the reduction of the urban–rural gap. Male mortality rates in urban areas have surpassed those of women. At the same time, the mortality rate of diabetes showed obvious elder-group orientation. As China’s population ages, the burden of death and disability caused by diabetes and its complications will continue to increase. These results indicate that diabetes has become a significant public health problem in China. Such an effect increases the demand for strategies aimed at the prevention and treatment of diabetes mellitus. In addition to the prevention and intervention of diabetes in high-risk groups, it is also necessary to establish diabetes screening networks to identify patients with mild symptoms. Early detection and timely intervention can effectively reduce the incidence and mortality of diabetes.

Abstract Background Since 2011, there has been an increase in the incidence of scarlet fever across China. The main objective of this study was to depict the spatiotemporal epidemiological characteristics of the incidence of scarlet fever in Shenyang, China, in 2018 so as to provide the scientific basis for effective strategies of scarlet control and prevention. Methods Excel 2010 was used to demonstrate the temporal distribution at the month level and ArcGIS10.3 was used to demonstrate the spatial distribution at the district/county level. Moran’s autocorrelation coefficient was used to examine the spatial autocorrelation and the Getis-Ord statistic was used to determine the hot-spot areas of scarlet fever. Results A total of 2314 scarlet fever cases were reported in Shenyang in 2018 with an annual incidence of 31.24 per 100,000. The incidence among males was higher than that among females(p<0.001). A vast majority of the cases (96.89%) were among children aged 3 to 11 years. The highest incidence was 625.34/100,000 in children aged 5–9 years. In 2018 there were two seasonal peaks of scarlet fever in June (summer-peak) and December (winter-peak). The incidence of scarlet fever in urban areas was significantly higher than that in rural areas(p<0.001). The incidence of scarlet fever was randomly distributed in Shenyang. There are hotspot areas located in seven districts. Conclusions Urban areas are the hot spots of scarlet fever and joint prevention and control measures between districts should be applied. Children aged 3–11 are the main source of scarlet fever and therefore the introduction of prevention and control into kindergarten and primary schools may be key to the control of scarlet fever epidemics.

Introduction: Cancer is an important cause of morbidity and mortality worldwide. Population-based cancer registries (PBCRs) make possible to estimate the burden of this condition. Objetive: To estimate cancer incidence and mortality rates in the Bucaramanga Metropolitan Area (BMA) during 2003-2007. Methods: Incident cases of invasive cancer diagnosed during 2003-2007 were identified from the Bucaramanga Metropolitan Area PBCR (BMA-PBCR). Population counts and mortality were obtained from the Colombian National Administrative Department of Statistics (NADS). We estimated total and cancer-specific crude incidence and mortality rates by age group and sex, as well as age-standardized (Segi’s world population) incidence (ASIR[W]) and mortality (ASMR[W]) rates. Statistical analyses were conducted using CanReg4 and Stata/IC 10.1. Results: We identified 8,225 new cases of cancer excluding non-melanoma skin cancer (54.3% among women). Of all cases, 6,943 (84.4%) were verified by microscopy and 669 (8.1%) were detected only by death certificate. ASIR(W) for all invasive cancers was 162.8 per 100,000 women and 177.6 per 100,000 men. Breast, cervix, colorectal, stomach and thyroid were the most common types of cancer in women. In men, the corresponding malignancies were prostate, stomach, colorectal, lung and lymphoma. ASMR(W) was 84.5 per 100,000 person-years in women and 106.2 per 100,000 person-years in men. Breast and stomach cancer ranked first as causes of death in those groups, respectively. Conclusion: Overall, mortality rates in our region are higher than national estimates possibly due to limited effectiveness of secondary prevention strategies. Our work emphasizes the importance of maintaining high-quality, nationwide PBCRs.

Abstract Although overall life expectancy in the US has improved rapidly over the course of the 20th century and the racial gap in all-cause mortality has declined in recent decades, geographical disparities in mortality have increased in the last three decades. This research aims to study racial and geographical disparities by comparing the race and sex-specific mortality trends of the US rural and urban populations. We created a longitudinal county level analytic file of the US population 65 years and older, over the period of 1968 to 2015 obtained from CDC-WONDER and Area Health Resources Files. First, we used an OLS regression of age-adjusted mortality rate onto year indicators interaction with race and gender to depict the race and sex-specific trend in age-adjusted mortality rates. We also estimated the change in in mortality rate over time, for each race and gender, relative to values in 1968. Finally, we estimated race and sex specific trend in rural-urban mortality gap using state fixed effects regression. Our results indicate that racial gap in mortality rates has only declined in urban areas. Mortality rates of the whites in rural areas declined more rapidly than their Black counterparts, resulting in a gap that has been widening in the last three decades. The racial gap has increased considerably for males residing in rural counties not adjacent to an urban county. Thus, racial disparity in mortality has increased in rural areas, with a considerable widening between white and black male population living in the more remote rural areas.

Background. Few accurate up-to-date studies provide liver cancer mortality and survival information in Zhejiang province. This research aimed to depict the mortality and survival of liver cancer in Zhejiang province in China during 2005-2010. Methods. The data were collected from the Zhejiang Chronic Disease Surveillance Information and Management System, and the mortality rates of liver cancer were calculated by gender, age, and areas. Chinese population census in 2000 and Segi’s world population were used for age-standardized mortality rate. The observed and relative survival rates of liver cancer patients were analyzed. Results. The crude mortality rate of liver cancer was 32.11/105. The age-standardized mortality rate was 17.39/105 and 23.07/105 by Chinese population (ASIRC) and Segi’s world population (ASIRW), respectively. The crude liver cancer mortality rate and age-standardized rate in urban areas were lower than those of rural areas. The overall 1-, 3-, and 5-year observed survival (OS) rates of liver cancer patients were 38.61%, 21.65%, and 16.83%, respectively. The 1-, 3-, and 5-year relative survival (RS) rates of liver cancer patients were 39.49%, 23.27%, and 19.09%, respectively. Survival rate decreased obviously within 1 to 5 years and then leveled off. It was shown that the male overall survival rate was higher than the female one and the difference was statistically significant (P<0.05). Conclusions. Both lower mortality and better survival rates were observed in urban areas, compared to rural areas. Relevant parties including government, public resource, and propaganda department should devote enough attention to rural areas.
