气候变化背景下环境危害因素与生命早期健康

【Abstract】

Environmental risk factors related to global climate change threaten human health through various direct and indirect pathways. Due to their unique physiological and metabolic conditions, pregnant women and fetuses are especially vulnerable to these environmental risks. According to the developmental origins of health and disease (DOHaD) theory, early-life exposure to adverse environmental conditions can not only increase the risk of adverse birth outcomes but also impact the health of offspring later in life. We identified extreme temperatures (including both extremely high and low temperatures, as well as heatwaves) and air pollution as significant factors affecting birth outcomes, and quantitatively estimated their effects. By constructing exposure-lag-response relationship models, we pinpointed the critical gestational weeks during which exposure to these environmental factors impacts birth outcomes. Additionally, we explored the social determinants and biological mechanisms through which these exposures influence birth outcomes.

全球气候变化背景下，不利的环境因素可通过一系列直接或间接的路径对人群健康产生广泛而复杂的影响。由于特殊的生理和代谢状况，孕妇和胎儿极易受到外界环境危险因素的影响，是气候变化的高度脆弱人群。而根据健康和疾病的发育起源学说（developmental origins of health and disease，DOHaD），生命早期不良环境因素暴露，不仅危害孕妇健康和增加不良出生结局风险，还会增加子代儿童期和成年后罹患慢性疾病的几率。我们开展了气候变化相关环境因素暴露对生命早期健康的影响研究，首先识别了极端气温（极端高温、极端低温和高温热浪）和空气污染是影响妊娠结局的不利环境因素，并定量估计了其健康危害效应；然后通过构建暴露-滞后-反应关系模型，揭示了极端气温和空气污染暴露影响出生结局的关键孕周；此外，初步探讨了极端温度和空气污染物暴露影响胎儿发育和新生儿健康的社会驱动因素和生物学机制。

气候变化对中国劳动生产率和安全户外活动的影响及适应措施研究【ABSTRACT】

The health risks associated with climate change are escalating, increasing the frequency and intensity of extreme weather events. Numerous regions have experienced record-high temperatures in China, with the national average temperature rising to the second highest in history, while precipitation levels have dropped to their lowest since 2012. Timely and adequate measures can mitigate climate changes health impacts and reduce economic losses for vulnerable populations and nations. Therefore, it is crucial to prioritize the health-related implications and their broader effects in addressing climate change. This study primarily evaluates the risks associated with high temperatures due to climate change on human activities (work and outdoor activities) in China and examines the effectiveness of adaptive measures in mitigating these risks. Climate change is considered to increase economic costs by worsening heat-related labor productivity loss and unsafe outdoor activities. While extensive global and national research has been conducted on this topic, few studies have analyzed subnational and individual economic impacts, potentially weakening local governments’ motivation to tackle climate change. Figuring out the most affected regions and vulnerable groups could help climate policymakers to identify priority regions and sectors to allocate adaptation resources efficiently, and enhance stakeholder engagement. This study adopted a provincial Computable General Equilibrium model by distinguishing different labors and regions in modelling work to address the aforementioned gap. The study estimated economic costs at different levels under three climate change scenarios (lower (SSP126), middle (SSP245), and higher (SSP585) warming scenario). This study also tracked the number of safe physical activity hours lost per capita per day at the provincial level when a heat index, which combines temperature and humidity, exceeded a threshold of 33 degrees.

气候变化带来的健康风险与日俱增，极端天气事件发生的频率和强度不断上升，许多地区气温记录屡创新高，全国平均气温攀升至历史第二高位，同时降水量自2012年以来创新低。采取及时、充分的措施不仅能减轻气候变化对健康的影响，还将减缓个体（脆弱人群）与国家的经济损失。因此，在应对气候变化的过程中，更应优先考虑健康问题的关联和影响。本研究将主要评估气候变化中高温对中国人群活动（工作和户外运动）的相关风险及其适应措施的改善效果。气候变化被认为通过加剧与高温相关的非安全户外活动时间以及劳动生产力损失而增加健康风险和经济成本。虽然在全球和国家层面上已经进行了一些相关研究，但针对次地方层面和个人经济影响的研究较少，找出受影响最严重的地区和脆弱人群，可以帮助气候政策制定者确定优先资源分配的区域和行业，提高利益相关方的参与度。在此次报告中，采用了省级可计算一般均衡模型，通过在模型中区分不同的劳动者和地区，来填补上述研究空白。研究在三种气候变化情景（低（SSP126）、中（SSP245）和高（SSP585）升温情景）下估算了不同层级的劳动力生产经济成本与户外安全活动时间损失及其可行适应措施的效果评估。同时评估不同省份每人每天损失的安全体育活动小时数。

多维度生活方式的改变与老年人健康

【ABSTRACT】

As global aging accelerates, the health of older populations has gained widespread attention across society. Dementia, especially Alzheimers disease (AD), is widely recognized as a multifactorial condition associated with aging. The 2024 update from the Lancet Commission on dementia highlights that nearly half of all dementia cases worldwide could be prevented or delayed by targeting 14 modifiable risk factors. Identifying these risk factors and biomarkers has thus become a critical goal in dementia research, aiming to enable the early prevention and diagnosis of AD and other age-related diseases.In this report, I will first discuss the epidemiological risk factors for AD and then introduce current global research on multidomain lifestyle interventions, with a particular focus on the FINGER study. Next, I will present the latest findings from the MIND-AD study, which emphasizes multidomain lifestyle interventions in patients with prodromal AD. Finally, I will explore the shared lifestyle risk factors between AD and ischemic stroke.

随着全球老龄化的加剧，老年人健康已成为社会日益关注的焦点。作为一种与老龄密切相关的疾病，老年痴呆已被广泛认为是由多种危险因素共同作用所引发的疾病。2024年《柳叶刀》关于痴呆预防、干预和护理的常设委员指出，通过应对14个可改变的风险因素，全球近一半的痴呆病例可以被预防或延缓。通过识别相关危险因素和生物标志物，实现老年痴呆及其他与年龄相关疾病的早期预防和早期诊断，是老龄科学研究者的共同目标。在本报告中，我将首先探讨老年痴呆的流行病学危险因素，随后介绍当前全球范围内有关老年痴呆多维度生活方式干预的研究，特别是FINGER研究。接下来，我将介绍最新的MIND-AD研究，重点讨论在早期痴呆患者中进行的多维度生活方式干预。最后，我将讨论阿尔茨海默病与缺血性中风之间的共同生活方式风险因素。
