As cities around the world continue to grow, it is important for urban planners and policy makers to understand how different urban configuration patterns affect the environment and human health. However, previous studies have provided mixed findings. We aimed to identify European urban configuration types, on the basis of the local climate zones categories and street design variables from Open Street Map, and evaluate their association with motorised traffic flows, surface urban heat island (SUHI) intensities, tropospheric NO<sub>2</sub>, CO<sub>2</sub> per person emissions, and age-standardised mortality.</p></div><div><h3>Methods</h3><p>We considered 946 European cities from 31 countries for the analysis defined in the 2018 Urban Audit database, of which 919 European cities were analysed. Data were collected at a 250 m × 250 m grid cell resolution. We divided all cities into five concentric rings based on the Burgess concentric urban planning model and calculated the mean values of all variables for each ring. First, to identify distinct urban configuration types, we applied the Uniform Manifold Approximation and Projection for Dimension Reduction method, followed by the k-means clustering algorithm. Next, statistical differences in exposures (including SUHI) and mortality between the resulting urban configuration types were evaluated using a Kruskal–Wallis test followed by a post-hoc Dunn's test.</p></div><div><h3>Findings</h3><p>We identified four distinct urban configuration types characterising European cities: compact high density (n=246), open low-rise medium density (n=245), open low-rise low density (n=261), and green low density (n=167). Compact high density cities were a small size, had high population densities, and a low availability of natural areas. In contrast, green low density cities were a large size, had low population densities, and a high availability of natural areas and cycleways. The open low-rise medium and low density cities were a small to medium size with medium to low population densities and low to moderate availability of green areas. Motorised traffic flows and NO<sub>2</sub> exposure were significantly higher in compact high density and open low-rise medium density cities when compared with green low density and open low-rise low density cities. Additionally, green low density cities had a significantly lower SUHI effect compared with all other urban configuration types. Per person CO<sub>2</sub> emissions were significantly lower in compact high density cities compared with green low density cities. Lastly, green low density cities had significantly lower mortality rates when compared with all other urban configuration types.</p></div><div><h3>Interpretation</h3><p>Our findings indicate that, although the compact city model is more sustainable, European compact cities still face challenges related to poor environmental quality and health.","PeriodicalId":48548,"journal":{"name":"Lancet Planetary Health","volume":"8 7","pages":"Pages e489-e505"},"PeriodicalIF":24.1,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2542519624001207/pdfft?md5=751d84e8c8ca3e0c9ced350c68345759&pid=1-s2.0-S2542519624001207-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141538786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet it is unclear whether climate change anxiety, which is understudied in representative samples, is a specific mental health threat, action motivator, or both, particularly in populations exposed to climate-change related disasters. We sought to examine the associations between exposure to hurricanes, climate change anxiety, and climate change actions and attitudes in a representative sample of US Gulf Coast residents.</p></div><div><h3>Methods</h3><p>This study used data from a 5-year, representative, prospectively assessed, probability-based, longitudinal cohort sample of residents in Texas and Florida (USA) exposed to exogenous catastrophic hurricanes rated category 3 or greater. Participants were adults aged 18 years and older and were initially recruited from the Ipsos KnowledgePanel in the 60 h before Hurricane Irma (Sept 8–11, 2017). Relationships between climate change anxiety, hurricane exposure, hurricane-related post-traumatic stress symptoms, general functional impairment, and climate change-related individual-level actions (eg, eating a plant-based diet and driving more fuel efficient cars) and collective-level actions (eg, petition signing and donating money) and climate change action attitudes were evaluated using structural equation modelling.</p></div><div><h3>Findings</h3><p>The final survey was completed by 1479 individuals (787 [53·2%] women and 692 [46·8%] men).

Mean values were low for both climate change anxiety subscales: cognitive-emotional impairment (mean 1·31 [SD 0·63], range 1–5) and perceived climate change experience (mean 1·67 [SD 0·89], range 1–5); these subscales differentially predicted outcomes. The cognitive-emotional impairment subscale did not significantly correlate with actions or attitudes; its relationship with general functional impairment was attenuated by co-occurring hurricane-related post-traumatic stress symptoms, which were highly correlated with general functional impairment in all three models (all p<0·0001). The perceived climate change experience subscale correlated with climate change attitudes (<em>b</em>=0·57, 95% CI 0·47–0·66; p<0·0001), individual-level actions (<em>b</em>=0·34, 0·21–0·47; p<0·0001), and collective-level actions (<em>b</em>=0·22, 0·10–0·33; p=0·0002), but was not significantly associated with general functional impairment in any of the final models.

Coping with climate change, the radioactive water released into the Pacific Ocean subsequent to the Fukushima nuclear accident in Japan, and the wars in Ukraine and the Middle East (hereafter referred to as the wars) as individual crises can negatively affect the psychological health of young people, but little is known about the compounded impact of multiple crises. We aimed to examine: (1) the emotional responses of young people towards each individual crisis, (2) how aggregate levels of emotional engagement in global crises might pose different potential trajectories in psychological health, and (3) the protective or exacerbating role of media exposure and nature connectedness as mediators on psychological health outcomes of young people.</p></div><div><h3>Methods</h3><p>We conducted a cross-national online survey among young people (aged 18–29 years) from China, Portugal, South Africa, the USA, and the UK.
