摘要
目的:描述中国15省(自治区、直辖市)成年居民每日膳食嘌呤摄入状况、食物来源及变化趋势。方法:利用“中国健康与营养调查”1991—2018年间10轮随访数据,选择18岁及以上成年居民作为研究对象。采用“连续3天24小时”膳食回顾法调查居民食物摄入量和称重法调查调味品消费量。根据各类食物的消费数据和食物中嘌呤含量资料计算中国居民膳食嘌呤摄入量,并分析其食物来源。结果:与1991年相比,2018年中国成年居民总嘌呤、鸟嘌呤、腺嘌呤、次黄嘌呤、黄嘌呤中位数摄入量分别增加了75.9、21.0、12.9、36.5、2.0mg/d。来源于畜禽肉类的嘌呤比例从1991年的28.0%增加至2018年的30.4%,来源于水产品类的嘌呤比例从1991年8.2%增加至2018年的11.7%,来源于蔬菜类的嘌呤比例从1991年的21.5%下降至2018年的11.4%。结论:中国成年居民的膳食嘌呤摄入量呈上升趋势,食物来源主要是动物性食物和谷薯类,应引导居民合理膳食,减少高嘌呤食物的摄入。
【Objective】To describe the daily dietary purine intake,food sources and trends in 15 provinces(autonomous regions and municipalities directly under the central government)in China.【Method】Adult residents aged 18 years and older were selected as the study subjects using 11 rounds of follow-up data from the China Health and Nutrition Survey(CHNS)between 1991 and 2018.Dietary surveys were conducted using the three consecutive 24h dietary recalls method to investigate all the foods consumed by the residents and the weighing method to investigate the consumption of condiments.The dietary purine intake and food sources of Chinese residents was calculated based on the food consumption data and the purine content of foods.【Result】Dietary purine(total purine,guanine,adenine,hypoxanthine,xanthine)intake of Chinese adult residents showed an increasing trend from 1991 to 2018,and the dietary purine intake in 2018 increased by 75.9 mg/d,21.0 mg/d,12.9mg/d,36.5mg/d,and 2mg/d,respectively,compared with that in 1991.The proportion of purines from livestock and poultry meat increased from 28.0% in 1991 to 30.4% in 2018,the proportion of purines from seafood increased from 8.2% in 1991 to 11.7% in 2018,and the proportion of purines from vegetables decreased from 21.5% in 1991 to 11.4% in 2018.【Conclusion】The dietary purine intake of Chinese adult residents showed an increasing trend in 1991—2018,and the food sources were mainly animal foods and cereals and potatoes.It is necessary to guide residents to have a reasonable diet and reduce the intake of high purine foods.
