Xinhua News Agency, Los Angeles, March 20 (Reporter Tan Jingjing) According to a new study presented at this week's American Heart Association meeting, intermittent fasting that limits eating to less than eight hours a day may be linked to an increased risk of death from heart disease.
新华社洛杉矶3月20日电（记者谭晶晶）据一项在本周举行的美国心脏协会会议上提交的新研究，每天进食时间控制在8小时内的间歇性禁食方法可能与心脏病死亡风险上升相关。
Intermittent fasting, which has become increasingly popular in recent years, refers to restricting the time of eating and not eating for a period of time each day or week. The study focused on a form of "16:8" intermittent fasting, which involves eating only during an eight-hour window each day and fasting for the remaining 16 hours. Previous studies have shown that time-restricted eating can improve several measures of cardiometabolic health, such as blood pressure, blood sugar and cholesterol levels.
近年来越来越流行的间歇性禁食指限制进食时间，在每天或每周的一段时间内不进食。这项研究重点关注的是一种“16:8”间歇性禁食法，即每天只在8小时的窗口期内进食，剩余的16小时里禁食。此前一些研究显示，限时进食可以改善多项心脏代谢健康指标，比如血压、血糖和胆固醇水平等。
The new study analyzed data on the eating habits of about 20,000 U.S. adults (average age 49) collected from a scientific survey between 2003 and 2018 and compared it with data on population deaths from 2003 to the end of 2019 from the Centers for Disease Control and Prevention. They found that people who ate in just eight hours a day had a 91 percent higher risk of dying from heart disease than those who followed the traditional eating pattern of eating in 12 to 16 hours a day.
新研究分析了一个科研调查在2003年至2018年间收集的约2万名美国成年人（平均年龄49岁）的饮食习惯数据，并与美国疾病控制和预防中心2003年至2019年底的人群死亡数据相比较，发现每天仅在8小时内进食的人群与遵循每天在12至16小时内进食的传统饮食模式的人群相比，前者因心脏病死亡的风险高91%。
The study, based on observational analysis, also found that people with heart disease or cancer had a higher risk of death from cardiovascular disease if they followed this type of intermittent fasting. Time-restricted eating did not reduce the overall risk of death from any cause.
这项基于观察分析的研究还发现，如果遵循这种间歇性禁食方式，患心脏病或癌症的人群因心血管疾病死亡的风险更高。限时进食并不能降低任何原因导致的总体死亡风险。
Wenze Zhong, lead author of the study and head of the Department of Epidemiology and biostatistics at the School of Public Health at Shanghai Jiao Tong University, said it is important for patients, especially those with heart disease or cancer, to understand the association between the eight-hour eating window and an increased risk of death from cardiovascular disease. The findings encourage the public to choose their eating patterns more carefully and personalise them to ensure they are consistent with their health and the latest scientific evidence.
该研究主要作者、上海交通大学公共卫生学院流行病学与生物统计学系主任钟文泽说，对于病患，尤其是心脏病或癌症患者，了解8小时进食窗口与心血管疾病死亡风险增加之间的关联至关重要。该研究结果鼓励公众更谨慎地选取饮食模式，采取个性化方式，确保其符合个人健康状况以及最新科学研究证据。
The American Heart Association notes that all studies presented at its meetings are considered preliminary studies until they are formally published in a peer-reviewed journal. Chung also said that although the study found a possible association between 16:8 intermittent fasting and the risk of death from heart disease, it does not mean that time-restricted eating causes death from heart disease.
美国心脏协会指出，所有在该协会会议上提交的研究报告在正式发表于同行评议的学术期刊前都被视为初步研究。钟文泽也表示，尽管这项研究发现了“16:8”间歇性禁食法与心脏病死亡风险之间的可能关联，但这并不意味着限时进食会导致心脏病死亡。
