宁波市≥25岁人群身体活动不足归因死亡及对期望寿命影响

Effects of insufficient physical activity on mortality and life expectancy among adults aged 25 years and above in Ningbo city

目的探讨浙江省宁波市≥25岁人群身体活动不足对死亡和期望寿命的影响。方法通过2015年宁波市成人慢病监测调查获得身体活动数据,利用2015年宁波市死因监测数据、人口统计数据和2015年全球疾病负担研究(GBD)中身体活动不足相关疾病及其相对危险度数据,计算宁波市≥25岁人群身体活动不足相关疾病的归因分值,进而得到身体活动不足造成的归因死亡数和期望寿命损失。结果身体活动不足导致全死因归因分值为1.86%,男性为1.73%,女性为2.04%。其中,导致结直肠癌、乳腺癌、缺血性心脏病、缺血性脑卒中和糖尿病死亡的归因分值分别为11.81%、9.03%、7.31%、10.43%和12.98%。身体活动不足归因死亡总数为709人,其中,造成缺血性脑卒中死亡数最多,其次为缺血性心脏病,分别为246人和169人,其他依次为糖尿病152人、结直肠癌118人、乳腺癌23人。身体活动不足造成的人群期望寿命损失0.229岁,其中男性0.209岁,女性0.250岁;城市0.230岁,农村0.227岁。结论身体活动不足会加重人群疾病负担,增加人群身体活动会减少相关疾病的归因死亡和延长人群期望寿命。

Objective To explore the impact of insufficient physical activity(PA)on mortality and life expectancy among residents aged 25 years and above in Ningbo city of Zhejiang province.Methods The population data of the study included prevalence of PA collected from chronic diseases surveillance in adult residents in 2015,mortality of residents extracted from municipal death registry of 2015,demographic data,relative risks of diseases correlated with insufficient physical activity from Global Burden of Disease Study(GBD).Based on the data collected,we calculated insufficient PA-related population attributable fraction(PAF)of the diseases,attributable mortalities,and losses in life expectancy in 2015 for the population surveyed.Results The insufficient PA-related PAF for all cause of mortality was 1.86% among the residents surveyed and the PAF was 1.73% and 2.04% among the male and the female residents.The insufficient PA-related PAF for diseasespecific mortalities were 12.98%,11.81%,10.43%,9.03%,and 7.31% for diabetes,colon and rectum cancer,ischemic stroke,breast cancer,and ischemic heart disease,respectively.Among the residents in 2015,the number of all-cause mortality attributable to insufficient PA was 709 and the greatest number of disease-specific mortality was 246 for ischemic stroke,followed by 169,152,118,and 23 for ischemic heart disease,diabetes,colon and rectum cancer,and breast cancer.For the residents in 2015,insufficient PA-related reduction in life expectancy was 0.229 year for all the residents,with 0.209 and 0.250 year for the male and female residents,0.230 and 0.227 year for the urban and rural residents,respectively.Conclusion Insufficient physical activity has increased the burden of diseases among in residents Ningbo city and promoting physical activity could reduce attributed deaths and increase life expectancy in the population.
