This scoping review aims to synthesize the evidence on individuals' perspectives on reducing meat consumption to mitigate climate change. The three research questions focus on (1) the individuals' awareness of the link between meat consumption and climate change, (2) individuals' willingness to reduce their meat consumption to mitigate climate change, and (3) individuals who have already reduced their meat consumption for this purpose.</p><p><strong>Methods: </strong>This scoping review follows the extended PRISMA guidelines for scoping reviews. A systematic search was conducted in five databases (Medline, Scopus, Embase, Greenfile and PsynDex/CurrentContent/Agris via Livivo). Only peer-reviewed original studies, published since 2015, in English, German, Danish or Dutch were included. Two researchers performed all screening procedures.

The majority of studies were published since 2019, had a quantitative study design, and were conducted in Europe. Awareness of the link between meat consumption and climate change is low in most studies, and many people underestimate the climate change mitigation potential of meat consumption. Women and people with lower current meat consumption are more willing to reduce their meat consumption.

This study aimed to examine the marketing of ultra-processed foods on the most widely accessed radio stations across three counties in Kenya.</p><p><strong>Methods: </strong>This was a cross-sectional quantitative study conducted in three counties: Nairobi, Mombasa, and Baringo counties in the period between December 2021 to February 2022. We purposively selected 5 radio stations based on their popularity in different counties according to the Communications Authority of Kenya ratings. Using stratified sampling, we selected 8 recording days: 4 weekdays and 4 weekend days for three months. The recorded data were coded using a structured questionnaire. The key variables included the food and non-food and beverage products advertised on the radio stations, categorization of the food, non-food beverage products, time slots of the advertisements, promotional strategies, and premium offers.</p><p><strong>Results: </strong>Of the 1499 advertisements on the radio, 15.7% (n = 235) were food and beverage products. The most advertised food categories were sugar-sweetened beverages (44.7%) and alcoholic drinks (23.4%). Ultra-processed foods (UPFs) accounted for 58.3% of the non-alcoholic food and beverage product advertisements on the radio. There was a significantly higher level of UPFs during the weekdays (58.3%) compared to weekend days (39.0%) (p < 0.001), school holiday seasons (73.4%) compared to non-school holiday seasons (46.5%) (p < 0.001), and in urban areas (70.1%) compared to rural areas (34.5%) (p < 0.001).</p><p><strong>Conclusions: </strong>We observed a high level of UPF marketing across both rural and urban settings, with higher proportions recorded in urban areas and during school holiday periods. To support healthier food environments, there is a need for regulatory action targeting radio advertising of unhealthy foods. This may include restrictions during peak child listening hours, regulation of persuasive content, and clear identification of sponsored food promotions.</p>","PeriodicalId":36422,"journal":{"name":"BMC Nutrition","volume":"11 1","pages":"176"},"PeriodicalIF":2.2,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12490048/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145207909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
