Given the broad implications for such a paradox, which contradicts current public health guidelines for physical activity, we conducted a narrative, non-systematic review to discuss the current epidemiological and mechanistic evidence on the topic to inform opportunities for research and practice moving forward.</p><p><strong>Epidemiological evidence: </strong>Epidemiological evidence shows that LTPA is reliably protective against mortality and cardiovascular disease, whereas OPA has mixed or adverse associations. Several recent meta-analyses found higher all-cause mortality risk among men with high vs low OPA and found LTPA to potentially mitigate this OPA risk. Studies with device-measured OPA further highlight potential heterogeneity by OPA task and context. These conclusions remain limited by low quality evidence due to heterogeneous OPA exposure measurements, referent group selection, challenges in study design, and varied confounder adjustments.</p><p><strong>Mechanistic evidence: </strong>Mechanistically, four interrelated pathways that may explain the observed presence of a paradox have been proposed and preliminarily tested: (1) acute cardiovascular strain catalyzed by long-duration OPA with little recovery; (2) downstream vascular changes such as greater arterial stiffness, blunted baroreflex sensitivity, and maladaptive cardiac remodeling from chronic OPA exposure; (3) systemic inflammation associated with high OPA levels; and (4) modifiers such as low cardiorespiratory fitness and high psychosocial stress amplifying strain, inflammation, and risk. Current evidence is limited by reliance on cross-sectional or between-subject designs, crude OPA classification, and limited mechanistic interventions.</p><p><strong>Conclusions: </strong>Unlike the clear benefits from LTPA, research findings examining the health effects of OPA remain mixed. While uncertainty remains, the balance of evidence suggests that OPA is less beneficial to health than LTPA which should be considered in public health messaging. Advancing the field will require multidimensional OPA exposure assessment, rigorous study designs, and evaluation of mechanism-driven outcomes to clarify causal pathways and identify feasible intervention targets to promote health in workers with physically demanding jobs.</p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":" ","pages":""},"PeriodicalIF":5.5,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147857609","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}

While used often in behavioral health and other clinical settings, it remains untested in community public health contexts such as food retail. Healthy food retail strategies, including nutrition incentive programs, could benefit from measuring and subsequently strengthening leadership support to facilitate effective implementation. The objective of this study was to test the suitability of an adapted ILS to measure leadership support for a nutrition incentive program implemented in a brick-and-mortar food retail setting.</p><p><strong>Methods: </strong>As part of a larger evaluation, a multidisciplinary team of practitioners, evaluators, and food retail representatives created a modified version of the ILS suitable for the food retail context. Food retailer staff and management from one privately-owned grocery chain who participated in implementing a nutrition incentive program for Supplemental Nutrition Assistance Program (SNAP) shoppers in Southern California completed a survey that included the adapted ILS. Of the 522 survey respondents from the larger evaluation, 473 retailers including management and staff provided complete responses for the ILS. We assessed construct validity, internal consistency reliability, and measurement invariance using differential item functioning (DIF) analyses, Cronbach's alpha, confirmatory factor analysis (CFA), and multiple-group CFA for the adapted ILS.</p><p><strong>Results: </strong>DIF analyses indicated minimal evidence of measurement bias. The CFA supported the original four-factor ILS structure, with excellent internal consistency for the knowledgeable, supportive, and perseverant subscales and fair consistency for the proactive subscale. Further, the demonstrated measurement invariance between management and staff highlights the robustness of the ILS and its potential for assessing alignment or discrepancies in perceptions of implementation leadership between management and staff within food retail organizations.</p><p><strong>Conclusions: </strong>Findings suggest that the adapted ILS is a valid and reliable tool for measuring implementation leadership support for nutrition incentive programs in a food retail setting in the US.
