Study links lifestyle to rate of memory decline
歷時十年！科學家發現這6種生活方式可減緩記憶衰退
Memory loss is a common part of aging.
記憶力衰退是老年人的通病。
A decade-long study of older adults in China has found that a healthy lifestyle is linked to slower memory decline even when people carry a risky gene for Alzheimer's.
一項持續進行了10年的對中國老年人跟蹤調查研究顯示，即使攜帶有阿爾茨海默氏癥的危險基因，健康的生活方式與較慢的記憶力衰退相關。
Researchers from China's National Center for Neurological Disorders and other medical institutes followed 29,000 people aged at least 60 years with normal cognitive abilities for up to 10 years. Forty-nine percent of the participants were women.
來自中國國家神經疾病醫學中心和其他醫療機構的研究人員對2.9萬名60歲以上且認知能力正常的老年人進行了長達十年隨訪，研究對象中49%是女性。
At the beginning of the study in 2009, the researchers tested the participants' memory function with the Auditory Verbal Learning Test.
2009年研究開始時，研究人員使用聽覺詞語學習測驗（AVLT）來測試研究對象的記憶功能。
They were also tested for the APOE gene, the most common gene linked with Alzheimer's. Around 20 percent of the participants were carriers of the risk gene.
同時，他們還對研究對象體內最常見的與阿爾茨海默病有關的載脂蛋白E（apolipoprotein E, APOE）基因進行了檢驗，發現其中20%是攜帶者。
The participants received assessments in 2012, 2014, 2016 and 2019.
研究人員分別在2012、2014、2016和2019年對研究對象進行了隨訪評估。
In the follow-ups, six healthy lifestyle factors were analyzed: a healthy diet (adherence to recommended food items), regular physical exercise (at least 150 minutes of moderate intensity or 75 minutes of vigorous-intensity exercises per week), active social contact (for example, seeing friends and family at least twice a week), active cognitive activity (for example, reading, writing, playing chess at least twice a week), non-smoking and never drinking alcohol.
他們把六種健康生活特征納入了研究中。它們分別是：健康的飲食（遵守食品推薦攝入量）、定期的體育鍛煉（每周150分鐘及以上的中等強度運動或75分鐘及以上的劇烈運動）、頻繁的社交活動（每周兩次及以上看望朋友、家人等）、積極的認知活動（每周兩次及以上讀書、寫作、下棋等）、不抽煙、從不喝酒。
The results showed that the mean AVLT scores continuously declined over the 10 years.
測驗結果顯示，每個研究對象的聽覺詞語學習測驗成績在10年內持續下滑。
The highest test scores were in the favorable group and the lowest in the unfavorable group.
但是，良好生活方式組分數下降得最為平緩，不良生活方式組測驗分數最低。
The participants with favorable and average lifestyles, even when they were APOE carriers, had a slower rate of memory decline than the participants with unfavorable lifestyles.
良好和一般生活方式組中APOE基因攜帶者的記憶力下降速度也低于不良生活方式組。
Meanwhile, the results also showed that a favorable lifestyle was associated with a 90 percent lower probability of progression to mild cognitive impairment and dementia. The number for the average group was 30 percent.
與此同時，研究結果還表明，良好生活方式組與患輕度認知障礙和癡呆癥的可能性低近90%有關，一般生活方式組的數字是30%。
The researchers said that they studied the contribution of each lifestyle factor and their combined effects in a large sample size over an entire decade and offered important information to protect older adults against memory decline.
研究人員說，他們在整整十年的大樣本中研究了每種生活方式因素的貢獻，以及它們的綜合影響，為保護老年人免受記憶力衰退提供了重要信息。
The results about the APOE carriers also provide an optimistic outlook that healthy lifestyle risks are associated with a slower rate of memory decline, regardless of the genetic risk.
此項研究也給APOE基因的攜帶者也提供了一個樂觀的前景，即，無論遺傳風險如何，健康的生活方式與記憶力衰退速度放緩有關。
