耶鲁大学研究发现，近一半老年人的状况随着年龄增长而改善

* *Translation:* ……身体和心理能力。（or just translate the fragment: 身体和心理能力。）Since it starts with lowercase "oth", it's definitely a fragment. I will translate it as a fragment to be faithful to the input. * *Draft:* 身体和心理能力。 * **Segment 2:** "However, new research from Yale University paints a far more optimistic picture. The study found that many older adults actually improve over time, and their beliefs about aging may play an important role in those gains." * *Draft:* 然而，耶鲁大学的一项新研究描绘了一幅更为乐观的图景。该研究发现，许多老年人的能力实际上随时间推移有所提高，而他们对衰老的信念可能在这些改善中发挥了重要作用。 * **Segment 3:** "Drawing on more than a decade of data from a large, nationally representative study of older Americans, researchers discovered that nearly half of adults age 65 and older experienced measurable improvements in cognitive function, physical function, or both." * *Key terms:* "Drawing on" (利用/基于), "nationally representative study" (全国代表性研究), "measurable improvements" (可测量的改善). * *Draft:* 研究人员利用一项针对美国老年人的大型全国代表性研究中超过十年的数据，发现近一半65岁及以上的成年人在认知功能、身体功能或两方面都有可测量的改善。 * **Segment 4:** "The findings suggest that improvement in later life is far more common than many people realize." * *Draft:* 研究结果表明，晚年生活的改善远比许多人意识到的要普遍。 * **Segment 5:** "“Many people equate aging with an inevitable and continuous loss of physical and cognitive abilities,” said Becca R. Levy, lead author of the study and professor of social and behavioral sciences at the Yale School of Public Health (YSPH). “What we found is that improvement in later life is not rare, it’s common, and it should be included in our understanding of the aging process.”" * *Key terms:* "equate... with..." (将……等同于……), "inevitable and continuous loss" (不可避免且持续的丧失), "Yale School of Public Health" (耶鲁大学公共卫生学院). * *Draft:* “许多人将衰老等同于身体和认知能力的不可避免且持续的丧失，”该研究的主要作者、耶鲁大学公共卫生学院（YSPH）社会与行为科学教授贝卡·R·利维（Becca R. Levy）说，“我们发现晚年生活的改善并非罕见，而是普遍存在的，这应被纳入我们对衰老过程的理解中。” * **Segment 6:** "The study was published in the journal *Geriatrics*." * *Draft:* 该研究发表在《老年医学》期刊上。 * **Segment 7:** "Aging and Improvement Over Time" (Heading) * *Draft:* 衰老与随时间推移的改善 * **Segment 8:** "The research team analyzed data from more than 11,000 participants in the Health and Retirement Study, a federally funded long-term survey of older Americans." * *Key terms:* "Health and Retirement Study" (健康与退休研究 - standard translation), "federally funded" (联邦资助的). * *Draft:* 研究团队分析了“健康与退休研究”中超过11,000名参与者的数据，这是一项由联邦资助的美国老年人长期调查。 * **Segment 9:** "To measure changes in mental abilities, the researchers used a global cognitive assessment. Physical function was evaluated through walking speed, a measure often considered by geriatricians to be a key indicator of overall health because it is closely linked to disability, hospitalization, and mortality." * *Key terms:* "global cognitive assessment" (整体认知评估/综合认知评估), "walking speed" (步行速度), "geriatricians" (老年病学家/老年医学专家), "disability, hospitalization, and mortality" (残疾、住院和死亡率). * *Draft:* 为了测量心理能力的变化，研究人员使用了整体认知评估。身体功能则通过步行速度进行评估，老年医学专家通常认为步行速度是整体健康的关键指标，因为它与残疾、住院和死亡率密切相关。 * **Segment 10:** "Participants were followed for as long as 12 years. During that period, 45% showed improvement in at least one of the two areas examined." * *Draft:* 参与者接受了长达12年的随访。在此期间，45%的人在所考察的两个领域中至少有一个领域表现出改善。 * **Segment 11:** "Approximately 32% improved cognitively, while 28% improved physically. Many participants experienced gains large enough to be considered clinically meaningful. When researchers also counted individuals whose cognitive abilities remained stable rather than declining, more than half of participants avoided the commonly held expectation of cognitive deterioration." * *Key terms:* "clinically meaningful" (具有临床意义), "stable rather than declining" (保持稳定而非衰退), "cognitive deterioration" (认知恶化/衰退). * *Draft:* 约32%的人在认知方面有所改善，而28%的人在身体方面有所改善。许多参与者的改善幅度之大足以被认为具有临床意义。当研究人员也将认知能力保持稳定而非衰退的个体计算在内时，超过一半的参与者避免了人们普遍预期的认知衰退。 * **Segment 12:** "“What’s striking is that these gains disappear when you only look at averages,” said Levy, author of the book *Breaking the Age Code: How Your Beliefs About Aging Determine How Long & How Well You Live*. “If you average everyone together, you see decline. But when you look at individual trajectories, you uncover a very different story. A meaningful percentage of the older participants that we studied got better.”" * *Key terms:* "striking" (引人注目的), "individual trajectories" (个体轨迹), "Breaking the Age Code..." (书名翻译：《打破年龄密码：你对衰老的信念如何决定你的寿命和生活质量》). * *Draft:* “引人注目的是，如果只看平均值，这些改善就会消失，”利维说道，她是《打破年龄密码：你对衰老的信念如何决定你的寿命和生活质量》一书的作者。“如果你把所有人平均来看，你会看到衰退。但当你观察个体轨迹时，你会发现一个截然不同的故事。我们研究的老年参与者中，有相当大比例的人情况好转了。” * **Segment 13:** "The Role of Positive Age Beliefs" (Heading) * *Draft:* 积极衰老信念的作用 3. **Review and Refine:** * *Fragment handling:* The first sentence starts with "oth physical...". I will translate it as "……身体和心理能力。" to indicate the cut-off, or just "身体和心理能力。" given the instruction to just translate. I'll stick to the text provided. * *Formatting:* I will use standard paragraph breaks to replace the HTML tags for readability, as is standard for translation outputs unless HTML preservation is requested. * *Accuracy Check:* * "nationally representative study" -> 全国代表性研究. * "measurable improvements" -> 可测量的改善. * "Geriatrics" -> 《老年医学》. * "Health and Retirement Study" -> 健康与退休研究. * " 研究人员还探讨了为什么有些老年人有所改善，而另一些人则没有。 他们提出，一种可能性是研究开始时持有的年龄观念的影响。具体而言，他们考察了参与者是否持有更积极或更消极的衰老观念。 他们的分析支持了这一观点。持有更积极衰老观念的老年人，其认知表现和步行速度得到改善的可能性显著更高。即使在调整了年龄、性别、教育程度、慢性疾病、抑郁症和随访时长等因素后，这种关系依然显著。 这些发现建立在 Levy 的刻板印象具身化理论之上。该理论提出，通过社交媒体和广告等渠道从社会中吸收的与年龄相关的刻板印象，最终可能变得对个人具有意义，并产生可测量的生物学效应。 Levy 领导的先前研究发现，消极的衰老观念与记忆力较差、步行速度较慢、心血管风险增加以及与阿尔茨海默病相关的生物标志物有关。 据 Levy 所述，新的研究结果表明，相反的模式也可能发生。 Levy 表示，当前研究表明，那些内化了更积极年龄观念的人往往会表现出改善。 “我们的研究结果表明，晚年往往存在改善的储备能力，”她说，“而且由于年龄观念是可以改变的，这为个人和社会层面的干预措施打开了大门。” **挑战关于衰老的假设** 这些改善并不局限于那些在研究开始时就有身体或认知障碍的人。 研究人员发现，即使是那些认知和身体功能起始水平正常的参与者，随着时间的推移也经常有所改善。这一发现挑战了那种认为晚年能力的提升仅仅反映了病后康复或挫折后恢复到先前水平的观点。 作者希望这些结果将有助于转变公众对衰老的看法，并减少认为持续衰退不可避免的信念。他们还指出，这些发现支持加大对预防保健、康复项目以及其他健康促进服务的投入，以帮助老年人增强其复原力和改善能力。 *耶鲁大学医学院职业医学讲师及耶鲁大学公共卫生学院（YSPH）环境卫生科学系讲师 Martin Slade 为该研究的合著者。* 本研究得到了美国国立衰老研究所的资助。
