肥胖对COVID-19的影响及其饮食防控措施

IMPACT OF OBESITY ON COVID-19 AND ITS DIETARY PREVENTION AND CONTROL MEASURES

新型冠状病毒肺炎(新冠肺炎,COVID-19)疫情成为全球大流行以来,给人类健康、生活带来了新的极大挑战。本文通过回顾文献,综合分析肥胖与新冠肺炎疫情存在耦合作用,肥胖会引起人体的慢性炎症、呼吸系统障碍、维生素D和其他微量营养素缺乏以及菌群失调,从而影响COVID-19的易感性、疾病严重程度以及机体对新冠疫苗的反应。COVID-19疫情会引起心理压力、睡眠障碍、久坐行为增多、快餐和过度加工食品的摄入增加,从饮食行为和生活方式、社会经济地位和生理心理三个层面产生影响,增加肥胖的发生风险。目前全球超过50%的人口超重或肥胖,新冠肺炎确诊人数已经快速增加到4.7亿以上。根据公共卫生防控理论,本文提出以合理膳食行动为核心的综合方案是防控肥胖和新冠肺炎疫情的优化策略。

Since the global pandemic of COVID-19,a huge challenge has been brought to human health and life.Here,we review the literature and present a comprehensive analysis to identify the relationship between obesity and CDVID-19.Obesity can cause chronic inflammation,respiratory impairment,vitamin D and other micronutrient deficiencies,and dysbiosis in humans,thereby affecting susceptibility and disease severity of COVID-19,as well as the body’s response to the vaccine.The COVID-19 outbreak causes psychological stress,sleep disturbance,increased sedentary behavior,and increased intake of fast foods and overprocessed foods,which will increase the risk of developing obesity.Over 50%of the world’s population is currently overweight or obese,and the number of COVID-19 cases has rapidly increased to over 470 million.According to the theory of public health prevention and control,we propose that a comprehensive program with rational dietary action as the core is the optimal strategy for and controlling preventing and controlling obesity and COVID-19.
