Trends in Diabetes Mortality in Urban and Rural China, 1987–2019: A Joinpoint Regression Analysis

Abstract

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.

Activities of daily living and its influencing factors for older people with type 2 diabetes mellitus in urban communities of Fuzhou, China

“…The aging of Fuzhou's population is still ongoing at a rapid pace, and the proportion of people aged >60 years increased from 12.1% in 2011 to 19.1% in 2020 ( 13 ). In terms of T2DM, the age-standardized prevalence rate (12.3%) of T2DM in Fuzhou was slightly higher than the national average level (11.2%) in 2017 and similarly for the age-standardized mortality rate (14.7 per 100,000 vs. 12.7 per 100,000) ( 14 – 16 ). Since 2009, Chinese government launched the National Basic Public Health Service Program (NBPHSP) to provide 14 categories of health services to all urban and rural residents free of charge.…”

Comparison Study of Type 2 Diabetes Mellitus Incident in Urban Areas and Rural Areas in Banten

“…Secara nasional hampir separuh penduduk (48,2%) kurang melakukan aktivitas fisik secara teratur. (5) Hasil Penelitian ini sejalan dengan penelitian yang telah dilakukan oleh Mohan bahwa Banyak kasus diabetes di dunia ditemukan di daerah perkotaan, sebagaimana halnya yang dikemukakan oleh Mohan bahwa kasus diabetes tertinggi ditemukan di daerah perkotaan yaitu sebesar 7,3% dan terendah di daerah pedesaan sebesar 3,1%. Beliau juga mengatakan bahwa ada hubungan antara daerah perkotaan dengan kasus diabetes mellitus dengan OR sebesar 2,48.…”

Geographic heterogeneity of the epidemiological impact of the COVID-19 pandemic in Italy using a socioeconomic proxy-based classification of the national territory

“…Living in an urban context is associated with a higher incidence of environmental pollution-related diseases (9), while in rural areas higher incidences of and mortality due to diabetes (8,10,11), screening-preventable (12,13) or lifestyle-associated (13) cancer, and suicide (14) have been observed. Regarding cardiovascular diseases, the evidence has not always been consistent (8,15).…”
