Impact of injury-related mortality on life expectancy in Zhejiang, China based on death and population surveillance data

Abstract

BackgroundLife expectancy is a statistical measure of the average time an organism is expected to live. The purpose of this study was to evaluate the impact of injury-related mortality on life expectancy in Zhejiang Province.MethodsOur study used standard life tables to calculate life expectancy and cause-removed life expectancy based on mortality data from the Zhejiang Chronic Disease Surveillance System.ResultsLife expectancy of residents in Zhejiang was 77.83 years in 2013, with females having a higher life expectancy than males. The decrease in life expectancy caused by injury-related deaths was 1.19 years, the effect of which was reduced for females and urban residents compared with males and rural residents. The greatest impact on life expectancy was road traffic injuries (RTIs), (0.29 years lost overall, 0.36 for men vs. 0.21 for women and 0.26 for urban residents vs. 0.31 for rural residents). The main causes were falls (0.29 years lost overall, 0.30 for men vs. 0.28 for women and 0.28 for urban residents vs. 0.30 for rural residents), followed by drowning (0.15 years lost), suicide (0.11 years lost), and poisoning (0.04 years). For children less than 5 years old and elders aged over 65, drowning had a greater impact than falls.ConclusionsOur findings indicate that injury deaths had a major impact on life expectancy in Zhejiang. More attention should be paid to road traffic injury, and preventive action should be taken to reduce injury-related deaths to increase life expectancy, especially in children under five years of age and the elders over 65 years of age.

Healthy China 2030: how to control the rising trend of unintentional suffocation death in children under five years old

“…Injuries mainly include road traffic injuries, suicide, falls, and drowningdrowning [2]. Life expectancy in developing countries is reduced by 1.19 years due to injury [3]. In China [4], the proportion of injury deaths among 0-14 years of children in China rose from 18.69% in 2004 to 21.26% in 2011.…”

Synergistic influence of education and marriage on the risk for cognition loss among the older people in China

“…Therefore, it is reasonable to suggest that widowed older people should be investigated separately rather than in conjunction with those who are single or divorced. Despite women having longer life expectancies than men [26], we found that high-aged older people men and women had similar high widowhood rates. This nding suggests that it is more di cult to continue marriage at an advanced age than to extend the life of high-aged older people individuals.…”

Education and marriage synergistically protect oldest old against severe cognitive impairment

“…Therefore, it is reasonable to suggest that widowed older persons should be investigated separately rather than in conjunction with single or divorced elderly people. Despite women have longer life expectancies than men [26], we found that high-age elderly men and women had similar high widowhood rates. This finding suggests that it is more difficult to continue marriage at an advanced age than to extend life itself for both long-lived men and women.…”
