Being breastfed also predicts later body mass index. One hypothesis is that breastfeeding provides regular practice at autonomous appetite regulation: Because mothers cannot gauge exact amounts of milk consumed from breasts, they may let infants use their own internal satiation cues to regulate consumption rather than rely on external cues (e.g., quantity of milk left in bottles). Indeed, multiple studies report that breastfed infants demonstrate better appetite regulation later on than bottle-fed infants. Beyond appetite regulation, however, breastfeeding may also provide early and regular inhibitory control training, more generally. To examine longitudinal associations, we conducted secondary analyses of data from the Québec Longitudinal Study of Child Development. When 572 infants were 5- and 17-month-olds, mothers reported on whether and for how long they breastfed. Children were later assessed on executive function and behavior, including inhibitory control assessed using both direct behavioral assessments and mother-reported hyperactivity and inattention (everyday indicators of poor inhibitory control). We found that breastfeeding during infancy predicted inhibitory control at 3.5 years of age, even after controlling for significant covariates, supporting the idea that breastfeeding may provide a natural means of introducing early and regular inhibitory control practice and that practice in one inhibitory control domain may promote improvements in other domains.</p>","PeriodicalId":242,"journal":{"name":"Appetite","volume":" ","pages":"108568"},"PeriodicalIF":3.8,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147758657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lack of consumer willingness has been identified as a barrier to adopt biodiversity-friendly agricultural practices, however, a consumer perspective remains underexplored. This paper presents findings from four focus group discussions in the Netherlands with a relatively environmentally-conscious sample (N = 24), exploring how they perceive biodiversity-friendly production and consumption. These discussions reveal two main insights: first, participants are aware of the negative ecological impacts of food systems and can identify key drivers of biodiversity loss, such as increased chemical inputs, monocultures and unsustainable consumption patterns. They recognize the systemic nature of these problems, describing the system as ‘locked in’ by economic and institutional constraints. Second, while participants stress the role of consumers in driving food systems (change), they simultaneously express ambivalence around their own agency to do so. Mapped according to the COM-B model, the study identifies drivers and barriers related to people's perceived capability (e.g., limited visibility of biodiversity), opportunity (e.g., limited availability and accessibility of alternatives), and motivation (e.g., conflicting priorities) to consume in a more biodiversity-friendly way. We argue that this tension between responsibility and agency reflects a broader discourse of consumer responsibilization, in which individuals are assigned responsibility for solving broader problems through their consumption, without being given the means to. The study demonstrates the need for systems that enable biodiversity-friendly food consumption, as well as foster a more balanced societal discourse on responsibility and agency in food systems.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"219 ","pages":"Article 108426"},"PeriodicalIF":3.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145773147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the PEA-Q's ability to adequately capture pregnancy-specific eating/weight attitudes <em>across</em> pregnancy, we employed longitudinal measurement invariance (MI) testing among a community sample of pregnant individuals with pre-pregnancy body mass index≥25. Participants (<em>N</em> = 312) enrolled in a randomized perinatal health behavior trial completed the PEA-Q at <em>M</em>(<em>SD</em>) = 13.6(2.7) and 36.5(1.3) weeks' gestation. We performed longitudinal MI testing in steps to establish equivalence of the PEA-Q at early and late pregnancy and to compare PEA-Q scores between these timepoints. Models covaried for randomization status. Partial strong invariance was ultimately achieved by freeing the intercepts of one item. Results from latent mean difference testing documented significantly lower scores on Permissive Eating/Weight Attitudes and Lack of Worry about Eating/Weight (<em>p</em> ≤ .01), but not Intentional Eating Changes (<em>p</em> = .08), in early versus late pregnancy. Findings indicate that the PEA-Q adequately captures pregnancy-specific eating/weight attitudes in both early and late pregnancy and, thus, can be used to assess change over this period. In the present sample, changes in PEA-Q scores from early to late pregnancy suggest that pregnant individuals may experience increasingly permissive eating/weight attitudes and less worry about eating/weight as pregnancy progresses.

Behavioral results revealed that time pressure altered choice patterns across genders, with no gender differences in response times or healthier choices under both time conditions. Hierarchical drift-diffusion modeling (HDDM) revealed three key mechanisms. First, male participants shifted from deliberative health-taste integration to hedonic-dominant processing under time pressure, whereas female participants maintained stable taste-focused strategies. Second, both genders showed reduced decision thresholds under time constraints, requiring less evidence for choices.
