Here, we quantified and assessed the nature of the relationship between hedonic hunger and BMI, in a cross-sectional study using the Portuguese version of the PFS (P-PFS) to measure hedonic hunger. Data were collected from 1266 participants belonging to non-clinical, clinical (candidates for weight-loss surgery) and population samples. Across samples, significant but weak positive associations were found between P-PFS scores and BMI, in adjusted linear regression models. However, in logistic regression models of data from the clinical and non-clinical samples, the P-PFS Food Available domain score was significantly and robustly associated with belonging to the clinical sample (OR\u2009=\u20091.8, 95%CI: 1.2\u20132.8; p\u2009=\u20090.008), while in the population sample it was associated to being obese (OR\u2009=\u20092.1, 95%CI: 1.6\u20132.7; p\u2009&lt;\u20090.001). Thus, hedonic hunger levels are associated with obesity status with the odds of being obese approximately doubling for each unit increase in the P-PFS Food Available score.<\/jats:p>","DOI":"10.1038\/s41598-018-23988-x","type":"journal-article","created":{"date-parts":[[2018,4,11]],"date-time":"2018-04-11T14:45:17Z","timestamp":1523457917000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":51,"title":["Association between hedonic hunger and body-mass index versus obesity status"],"prefix":"10.1038","volume":"8","author":[{"given":"Gabriela","family":"Ribeiro","sequence":"first","affiliation":[]},{"given":"Marta","family":"Camacho","sequence":"additional","affiliation":[]},{"given":"Osvaldo","family":"Santos","sequence":"additional","affiliation":[]},{"given":"Cristina","family":"Pontes","sequence":"additional","affiliation":[]},{"given":"Sandra","family":"Torres","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5071-3007","authenticated-orcid":false,"given":"Albino J.","family":"Oliveira-Maia","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2018,4,11]]},"reference":[{"key":"23988_CR1","doi-asserted-by":"publisher","first-page":"17610","DOI":"10.1523\/JNEUROSCI.3452-13.2013","volume":"33","author":"IN Karatsoreos","year":"2013","unstructured":"Karatsoreos, I.
