Physical activity should also be understood as a population condition shaped by governments, institutions, and markets through access to opportunity. This shift matters because individuals do not simply allocate movement, sitting, and sleep; labor, transport, housing, safety, gender, income, climate, commercial forces, and public infrastructure structure these activities. Moreover, in low-income settings and low- and middle-income countries, necessity often shapes activity, while choice-constrained conditions frequently limit leisure-time or volitional activity. A more equitable 24-hour framework should therefore move from movement behaviors alone to 24-hour living conditions, asking not only how time is spent but also how opportunity is distributed.</p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":"23 1","pages":""},"PeriodicalIF":7.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13660133/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149185705","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}

Increasingly, dissemination occurs within digital environments shaped by algorithms that prioritise engagement, simplicity, novelty, and emotional salience over nuance and uncertainty. This creates a mismatch between the complexity that characterises behaviour change science and the attention-driven logics that shape what evidence becomes visible.This Comment was prompted by our involvement in developing the NESI (Network of Early Career Researchers and Students of ISBNPA) Podcast and ASPA (Asia-Pacific Society for Physical Activity) Radio, initiatives designed to disseminate credible behavioural science. Despite prioritising high-quality, peer-reviewed research, we encountered persistent challenges in achieving visibility relative to simplified or commercially framed health narratives amplified in digital spaces.We argue that visibility in digital environments is algorithmically mediated in ways that can systematically disadvantage complex, context-dependent evidence characteristic of behavioural nutrition and physical activity research. We explore the risks of equating visibility with impact, including oversimplification and erosion of trust, while contending that disengagement from contemporary communication platforms is not viable for a field committed to translation. We propose reframing dissemination as a collective responsibility of researchers, journals, and professional societies, focused on stewardship, integrity, and principled engagement.

At its 2026 conference in Cádiz, Spain, ISBNPA asked presenters to declare the estimated carbon emissions from their travel to the conference. Well-intentioned as it is, viewed through a systems lens, such an intervention risks placing disproportionate emphasis on individual responsibility when it is not embedded within broader institutional and structural change.
