很少有研究使用全国代表性数据来描述中国的饮食趋势和相关的心血管代谢死亡负担。因此，我们的目的是了解1982 - 2012年中国成年人疾病相关饮食因素及其相关疾病负担的趋势。方法在这项基于横断面人群的研究中，我们分析了204802名20岁或以上成年人的全国代表性样本，使用1982年，1992年，2002年，以及2010-12年中国国民营养调查（CNNS）。我们做了一个比较风险评估，其中12个饮食因素的次优摄入量的影响，单独和集体，通过计算人群归因分数（PAF）估计如果暴露于每种饮食风险因素降低到另一个最佳水平，心血管代谢死亡率的比例降低。1982年、1992年、2002年和2010- 2012年，与膳食质量欠佳相关的疾病和2型糖尿病的死亡率分别为62.2%、57.9%、56.2%和51.0%，分别占中国1982年、1992年和2002年总死亡率的21.6%、16.6%和17.6%，2010-12年为20.8%。1982年，与次优膳食摄入量相关的心血管代谢死亡人数估计为107万，1992年为93万，2002年为118万，2010-12年为151万。2010- 2012年，在所有12种膳食因素中，高钠摄入（17.3%）、低水果摄入（11.5%）和低海洋ω-3脂肪酸（9.7%）与估计的心血管代谢性死亡人数最多相关。然而，目前这些饮食因素的摄入量仍然不理想。据估计，在中国，很大一部分死于心脏病、中风和2型糖尿病的人与不良的饮食质量有关。版权所有（C）2019 Elsevier Ltd.保留所有权利。
Background Few studies have used nationally representative data to describe dietary trends and the related cardiometabolic mortality burden in China. Thus, we aimed to characterise the trends in disease-related dietary factors as well as their associated disease burden among Chinese adults from 1982 to 2012.Methods For this cross-sectional population-based study, we analysed a nationally representative sample of 204802 adults aged 20 years or older, using data from the 1982, 1992, 2002, and 2010-12 China National Nutrition Surveys (CNNS). We did a comparative risk assessment, in which the effects of suboptimal intakes of 12 dietary factors, individually and collectively, on cardiometabolic mortality were estimated by calculating the population attributable fraction (PAF) to estimate the proportional reduction in cardiometabolic deaths that would occur if exposure to each dietary risk factor was reduced to an alternative optimal level.Findings The overall PAF of mortality from cardiovascular disease and type 2 diabetes that was associated with suboptimal dietary quality was 62.2% in 1982, 57.9% in 1992, 56.2% in 2002, and 51.0% in 2010-12, which accounted for 21.6% of total mortality in China in 1982, 16.6% in 1992, 17.6% in 2002, and 20.8% in 2010-12. The estimated number of cardiometabolic deaths associated with suboptimal dietary intakes was 1.07 million in 1982, 0.93 million in 1992, 1.18 million in 2002, and 1.51 million in 2010-12. Of all 12 dietary factors examined, high sodium intake 17.3%), low fruit consumption (11.5% ), and low marine omega-3 fatty acids (9.7%) were associated with the largest numbers of estimated cardiometabolic deaths in 2010-12.Interpretation We observed an improvement in several dietary factors in China in the past few decades. However, current intakes of these dietary factors remain suboptimal. Poor diet quality is estimated to be associated with a substantial proportion of deaths from heart disease, stroke, and type 2 diabetes in China. Copyright (C) 2019 Elsevier Ltd. All rights reserved.
