Objective: To quantitatively analyze the death and disability-adjusted life years (DALY) attributed to high level serum LDL-C in Chinese population in 2017. Methods: Data were obtained from the '2017 Global Burden of Disease Study (GBD2017)'. Population attributable fraction (PAF), number and rate of deaths and DALY attributable to high LDL-C were used to describe the burden of disease by gender, age groups, diseases and provinces in China. Both rates on mortality and DALY were standardized by GBD world population. Results: In 2017, 862 759 deaths were caused by high level serum LDL-C in China, that accounting for 8.25% of the total deaths. Of the attributable deaths, 705 355 (81.76%) persons died from ischemic heart disease (IHD), while the remaining 18.24% from ischemic stroke (IS). High LDL-C accounted for 40.30% of the total deaths from ischemic heart disease and 18.49% from ischemic stroke. The highest PAF of death (13.70%) appeared in Jilin province and the lowest in Zhejiang province (4.65%). PAF of death was seen higher in females than in males, while both age-standardized rates of mortality and DALY appeared higher in males than in females. High LDL-C attributed mortality rate appeared as 61.08/100 000 after standardization in Chinese population. High LDL-C attributed DALYs were 18.16 million person years, among which 76.76% were caused by IHD (13.94 million person years), with DALY rate as 1285.83/100 000. Among provinces, Heilongjiang showed the highest standardized DALY rate, and Zhejiang the lowest. The PAF, number of deaths, rates on mortality and DALY caused by high LDL-C were high among residents above 70 years old, with the DALY number as 8.56 million person years, highest seen in the age group from 50 to 69 years old. Conclusion: The burden of disease attributed to high level LDL-C was quite high and with gender, age group and interprovincial differences, in China in 2017.
目的： 定量研究中国人群高血清LDL-C归因死亡及伤残调整寿命年（DALY）。 方法： 利用2017年全球疾病负担研究（GBD2017）中国及各省数据，由人群归因分值（PAF）、归因死亡数及DALY，描述2017年高血清LDL-C对中国分性别、年龄别、疾病和不同省份人群归因死亡及伤残负担，利用GBD世界标准人口做标化后比较各组死亡率及DALY率。 结果： 2017年中国人群全死因死亡中归因于高血清LDL-C的人数为862 759人，占8.25%。归因死亡人数中有705 355人死于缺血性心脏病（IHD），占81.76%，其余18.24%死于缺血性卒中（IS）。高LDL-C对IHD死亡的PAF为40.30%，对IS死亡的PAF为18.49%。女性归因死亡比例高于男性，吉林省最高为13.70%，浙江省最低为4.65%。中国人群高LDL-C归因死亡率为61.08/10万，男性标化归因死亡率高于女性。高LDL-C造成的DALY为1 816.21万人年，其中归因IHD的DALY为1 394.15万人年，占76.76%。DALY率为1 285.83/10万，标化DALY率最高的省份为黑龙江省，最低为浙江省。人群死亡归因分值、归因死亡人数、归因死亡率及归因DALY率均在>70岁人群较高，DALY在50～69岁年龄组最高，为856.18万人年。 结论： 血清高LDL-C对中国人群归因死亡及伤残负担影响较大，且具有性别、年龄及省间差异。.
