<div><h3>Background</h3><div>Climate change-related heat stress disproportionately affects people in sub-Saharan Africa, impairing physical performance and increasing the risk of heat-related illnesses. Despite subsistence farming's key role in food security, scarce studies have measured farmers' physical effort during labour and the impact of behavioural adaptations to heat stress in real-life settings. This long-term, empirical study in Burkina Faso, one of the world’s resource-poorest countries, aimed to measure the heat stress-labour effort relationships among subsistence farmers, accounting for gender-related differences in labour roles.</div></div><div><h3>Methods</h3><div>We conducted a 1-year observational study using the Nouna Health and Demographic Surveillance System in Burkina Faso. We included participants who were healthy, actively practising farmers aged 20–45 years who were neither overweight nor underweight, had no chronic illnesses, no planned pregnancy or breastfeeding status, and resided within a 10-km radius of the weather station. Using research-grade wearables, we collected time-series data on environmental conditions, tracking indoor and outdoor wet-bulb globe temperature (WBGT) and physiological responses such as daily activity, estimated core body temperature, heart rate, and GPS-tracked movements. To operationalise physical effort during labour, we evaluated the physiological strain index (PSI; 0–10 scale with 10 being highest strain) and activity intensity during fieldwork, measured as functions of WBGT. Behavioural adaptations were measured using working patterns including work duration, break times, and seasonal work distribution. The main outcomes are compared across genders and complemented by analyses of monthly vital sign assessments and heat impact surveys.</div></div><div><h3>Findings</h3><div>Between Aug 9, 2021, and Aug 30, 2022, we recruited 39 subsistence farmer households (39 women, 39 men). One household dropped out of follow-up, and 38 households (76 participants [38 men, 38 women]) were included in the analysis. During fieldwork, PSI decreased as WBGT increased (–0·04 [95% CI –0·07 to –0·01], p=0·0056), suggesting adaptive pacing. Men reduced their average activity intensity once WBGT exceeded 27°C. By contrast, women experienced a higher PSI and activity intensity during fieldwork than men (PSI: 0·47 [0·07–0·87], p=0·025). Each 1°C WBGT rise extended daily working time by 12·3 min (95% CI 2·75–21·89, p=0·013) and participants shifted work patterns in response to heat stress by increasing break duration and shifting work to cooler times.</div></div><div><h3>Interpretation</h3><div>Heat stress significantly reduces the physical effort during labour.

背景：与气候变化相关的热应激对撒哈拉以南非洲地区的人们造成了不成比例的影响，损害了身体机能，增加了患与热有关疾病的风险。尽管自给农业在粮食安全方面发挥着关键作用，但很少有研究衡量农民在劳动期间的体力劳动以及在现实生活中对热应激的行为适应的影响。这项在布基纳法索（世界上资源最贫乏的国家之一）进行的长期实证研究，旨在衡量自给农民之间的热应激-劳动努力关系，并考虑到劳动角色的性别差异。方法：我们利用布基纳法索的Nouna健康和人口监测系统进行了为期1年的观察性研究。我们纳入了健康、积极从事农业活动、年龄在20-45岁之间、既不超重也不体重不足、没有慢性疾病、没有计划怀孕或母乳喂养状况、居住在气象站10公里半径范围内的参与者。使用研究级可穿戴设备，我们收集了环境条件的时间序列数据，跟踪室内和室外湿球温度（WBGT）和生理反应，如日常活动、估计的核心体温、心率和gps跟踪的运动。为了操作劳动期间的体力劳动，我们评估了野外工作期间的生理应变指数（PSI； 0-10量表，10为最高应变）和活动强度，作为WBGT的函数来测量。行为适应是通过工作模式来衡量的，包括工作时间、休息时间和季节性工作分配。主要结果在性别之间进行比较，并辅以每月生命体征评估和热影响调查的分析。研究结果：在2021年8月9日至2022年8月30日期间，我们招募了39个自给农户（39名女性，39名男性）。1个家庭退出随访，38个家庭（76名参与者[38名男性，38名女性]）被纳入分析。在野外工作中，PSI随着WBGT的增加而下降（- 0.04 [95% CI - 0.07至- 0.01],p= 0.0056），提示适应性起搏。一旦WBGT超过27°C，男性的平均活动强度就会降低。女性在野外工作中的PSI和活动强度均高于男性（PSI: 0.47 [0.07 - 0.87], p= 0.025）。WBGT每升高1°C，每日工作时间延长12.3分钟（95% CI 2.75 - 21.89, p= 0.013），参与者通过增加休息时间和将工作转移到较冷的时间来改变工作模式，以应对热应激。解释：热应激显著降低了分娩时的体力消耗。自谋生计的农民似乎通过降低劳动强度、在一天中重新分配任务以及将工作转移到较冷的月份来适应热应激。随着气候变化的恶化，这些适应可能会变得不够。女性往往要平衡家务和野外工作，她们的节奏策略有限，这使她们更容易受到日益严重的热应激的影响。我们的研究结果强调了迫切需要有针对性的适应策略，以在分娩期间保持体力劳动，并保护弱势群体，特别是妇女，免受不断升级的热应激。资助：德国研究基金会（DFG-German Research Foundation）。

Background
Climate change is recognised as a major global threat to human health in the 21st century. Health professionals are expected to play a crucial role in mitigating climate-related health risks and preparing health systems for emerging challenges. This study aimed to assess the knowledge and awareness of climate change and health impacts among members working at the health faculties of a public university in Istanbul.
Methods
This descriptive study targeted 494 faculty members across four faculties: Medicine, Dentistry, Health Sciences, and Pharmacy. An online questionnaire was provided between December, 2021 and April, 2022. 217 members responded. The survey included sociodemographic questions and items assessing knowledge and awareness of climate change and its health effects. Data were analysed using Pearson’s Chi-Square and Fisher’s Exact tests, with statistical significance set at p<0·05. Ethics approval was obtained.
Findings
Only 82 (37·8%) of 217 members correctly defined climate change, although 191 (88%) believed climate change aff5cts personal health and n=193 (89%) expressed concern about climate change. 145 reported modifying consumption habits due to climate change, whereas only 53 (24·4%) integrated the topic into their teaching. There were significant differences between gender and health-related perceptions and between faculty type and support for including climate change in the curriculum (p<0·001).
Interpretation
Despite high concern levels, faculty members had limited knowledge and showed low integration of climate change into educational content. Enhancing education on climate change and health impacts in the health students' curriculum is essential for advancing planetary health awareness and action.

Although degrowth is increasingly seen as essential to tackling climate change, the extent of public support for this economic approach remains unclear. In this study, we aimed to investigate public support for the full degrowth proposal in the UK and USA—high-income, growth-oriented nations with substantial climate responsibility and political resistance to degrowth.

Study 1 used a within-subjects design whereby all participants rated their support for the full degrowth proposal (summarising the key ideas, practices, and goals of degrowth) without any label and for eight economic approaches presented by label only (ie, degrowth, ecomodernism, ecosocialism, green capitalism, green growth, green market economy, post growth, and wellbeing economy) on a 7-point scale (from 1 [strongly oppose] to 7 [strongly support]). Study 2 used a between-subjects design whereby participants were randomly assigned using the randomiser function in Qualtrics, to one of seven economic approaches (the full degrowth proposal; a label referring to either degrowth, ecosocialism, or wellbeing economy without a description; or a combination of the full degrowth proposal with one of these three labels), for which they rated their support on the same 7-point scale. Mean support for each approach was classified on the basis of 95% CIs, meaning that similar means could be classified differently across studies and samples due to variations in these intervals.

Food education in schools is increasingly being adopted as one of the key policy levers to support the shift towards healthier and more sustainable food practices worldwide. However, the way in which food education is designed and implemented is not often conducive to such goals. We propose a food learning model and process for designing holistic food education that fosters food competent children and adolescents as catalysts for change. The model applies evidence-based core principles required for effective food education, such as action-oriented goals that align with a student's contexts, co-ownership of the learning process, prioritising experiential learning, ensuring purposeful interactions, complementarity with the school food environment and beyond, and meaningful involvement of actors that influence children's food practices and perspectives. The process for designing food education programmes is anchored in the food learning model and highlights the importance of selecting the right entry points in the formal school system, assessment of learning needs, co-formulating competences, and the need for continuous and purposeful assessments of students' learning. We highlight the key challenges beyond programme design that must be addressed to enhance the success of food education, including the need to strengthen systemic capacity and improve the wider policy environment.

We highlight the key challenges beyond programme design that must be addressed to enhance the success of food education, including the need to strengthen systemic capacity and improve the wider policy environment.</div></div>","PeriodicalId":48548,"journal":{"name":"Lancet Planetary Health","volume":"9 11","pages":"Article 101219"},"PeriodicalIF":21.6,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144144079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background
School meal programmes are thought to improve dietary behaviour in children, with benefits sustained throughout the life course, making them important catalysts for wider food-system change. However, only one in five children globally currently receives school meals. We estimated the potential effects of extending school meal coverage to all children by 2030 for dietary health; the environmental effects related to diets; and the costs of diets at global, regional, and national levels.
Methods
We conducted health, environmental, and cost assessments of future scenarios of school meal coverage, meal frequency, meal composition, and food wastage. In the health assessment, we used statistical methods and a comparative risk assessment to estimate short-term changes in undernourishment and long-term changes in dietary risks and mortality. In the environmental assessment, we used food-related environmental footprints to analyse how changes in dietary composition and food waste affect greenhouse gas emissions, land use, and freshwater use. In the cost assessment, we used an international dataset of food prices to estimate changes in diet costs, and we used estimates of the social cost of carbon and the costs of illness to estimate changes in the costs of climate-change damages and in health-related costs.
Findings
Extending school meal programmes to all children globally by 2030 could be associated with substantial health and environmental benefits globally and in each country. In the model assessments, the prevalence of undernourishment in food-insecure populations was reduced by a quarter due to having an additional meal at school; more than 1 million cases of non-communicable diseases were prevented globally per year if dietary habits were partly sustained into adulthood; and food-related environmental effects were halved if meal composition adhered to recommendations for healthy and sustainable diets and food waste was reduced. Increasing school meal coverage incurred additional meal-related costs that ranged from 0·1% of gross domestic product (GDP) in high-income countries to 1·0% of GDP in low-income countries. Reductions in the external costs of climate-change damages and the costs of illness compensated for the costs of providing meals in line with health and sustainable diets.
Interpretation
Universal school meal coverage could make important contributions to improving children’s health, the food security of their families, and the sustainability of food systems. However, dedicated policy and financial support will be required to close the gap in school meal coverage, especially in low-income countries.

Background
Amid global heating, establishing a heat-health warning system (HHWS) is crucial for reducing heat-related health risks. This paper presents an evidence-based HHWS app developed through stakeholder engagement.
Methods
Biometeorological, epidemiological, and risk communication challenges of heat-health risks across Taiwan were identified. To address these challenges we developed an app based HHWS, in collaboration with the Central Weather Administration and Health Promotion Administration in Taiwan.
Findings
Biometeorological results showed that the mean daily maximum wet-bulb globe temperature (WBGTmax) was 33·1 ± 3·8°C at 20 stations across Taiwan but could reach or exceed 36°C (threshold of the dangerous category) at some hot spots for 42·3–52·0% of the days between May and October from 2016 to 2022. Hot spots and periods identified using WBGT would be missed if temperature alone was used as the heat indicator. The relative risk (RR) for the heat-related emergency visits was 1·83 (95% CI 1·68–1·99) on day 0 when WBGT exceeded 32·5°C across Taiwan, based on a modified generalised additive model. Children aged 0–14 years had the highest RR (8·32, 1·96–35·3) on day 0, compared to adults aged 15–64 years and older. For risk communication, the frequency of warnings was evaluated to avoid excessive alerts, which could desensitise the public and strain resources of the authorities responsible for executing timely responsive programmes.
Interpretation
The developed HHWS was embedded in a mobile phone app, which all residents in Taiwan can download.
