摘要: 目的 了解辽宁彰武和凤城农村地区冠心病(coronary heart disease,CHD)的死亡趋势,以及CHD对该人群造成的疾病负担。方法 收集辽宁省彰武和凤城两地2009-2015年全死因死亡数据和人口学数据,计算死亡率、标化死亡率、早死所致健康寿命损失年(years of life lost,YLLs)、每千人YLL(YLL率)、标化YLL率、平均每人的健康寿命损失年(average years of life lost,AYLLs)、标化AYLLs及各指标随年份的变化趋势情况。结果 辽宁农村地区人群在2015年死亡率达最大值,为159.34/10万,且死亡率与年份呈正相关(rs=0.964,P<0.001),增长速度为5.51%。男性YLLs和人群YLLs均与年份呈正相关(均有P<0.05),增长速度分别为5.15%、4.25%;但女性的标化YLL率和AYLLs与年份呈负相关(均有P<0.05),下降速度分别为5.66%、1.65%。结论 辽宁农村地区人群在2009-2015年冠心病死亡率和YLL率呈现增长趋势,并且对该人群造成一定的疾病负担,应该对该人群展开相关教育及对冠心病的防治措施。Abstract: Objective To explore the trend of coronary heart disease(CHD) mortality and disease burden among Zhangwu and Fengcheng rural areas of Liaoning Province. Methods The all-cause mortality data and the demographic data of Zhangwu and Fengcheng areas in Liaoning Province from 2009 to 2015 were collected. Mortality, age standardized mortality, years of life lost (YLLs), YLL rate, age standardized YLL rate, average years of life lost (AYLLs), age standardized AYLLs and the change of all indexes with year were calculated. Results The maximum value of mortality was 159.34 per 100 000 among rural area of Liaoning Province in 2015. The mortality of CHD was positively correlated with time at a speed of 5.51% (rs=0.964, P<0.001). YLLs for male and population were positively correlated with time and increased with years at a speed of 5.15% and 4.25% respectively (all P<0.05), but age standardized YLL rate and AYLLs for female were negatively correlated with time and decreased with years at a speed of 5.66% and 1.65% respectively (all P<0.05). Conclusions There was a growing tendency of the mortality and YLL rate of CHD among rural areas of Liaoning from 2009 to 2015, and it brought burdens to people there. It is necessary to carry out health education about CHD and take further measures to prevent CHD.
