This study aimed to investigate the stability in BI perceptions and dissatisfaction during early adolescence. Another aim was to highlight differences in dissatisfaction according to Body Mass Index (BMI) and inconsistencies in weight status perception. Methods: Two hundred and nine participants (mean age at first survey: 11.33 \u00b1 0.38 years) were enrolled in this longitudinal study with three years of follow-up. Data on size and BI perceptions were collected through individual interviews. Stature and weight were directly measured. Results: Findings indicated significant changes over three years in anthropometric traits but not in weight status prevalence or BI perception and dissatisfaction, except for the ideal figure in males and weight control in females. The results also indicated a significant difference in BI perception and dissatisfaction by BMI categories. Self-reported body measurements were found to be unreliable with a weak-to-moderate agreement between self-perceived and actual weight status. Conclusions: BI perception appears quite stable across the three years considered. Dissatisfaction is similar in both genders, although a tendency toward different gender aesthetic ideals is already appreciable in early adolescence. We suggest that the lower frequency of normal-weight adolescents compared with peers in previous studies is attributable to the effects of the recent pandemic. Given the growing dissatisfaction with increasing BMI and misinterpretations of weight status, school actions to promote a healthy lifestyle and positive BI should be undertaken.<\/jats:p>","DOI":"10.3390\/nu16203439","type":"journal-article","created":{"date-parts":[[2024,10,11]],"date-time":"2024-10-11T03:53:47Z","timestamp":1728618827000},"page":"3439","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A Longitudinal Study on Body Image Perception and Size among Italian Early Adolescents: Changes over Time and Discrepancies between Genders"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7274-547X","authenticated-orcid":false,"given":"Emanuela","family":"Gualdi-Russo","sequence":"first","affiliation":[{"name":"Department of Neuroscience and Rehabilitation, Faculty of Medicine, Pharmacy and Prevention, University of Ferrara, 44121 Ferrara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5930-3661","authenticated-orcid":false,"given":"Sabrina","family":"Masotti","sequence":"additional","affiliation":[{"name":"Department of Neuroscience and Rehabilitation, Faculty of Medicine, Pharmacy and Prevention, University of Ferrara, 44121 Ferrara, Italy"},{"name":"Center for Exercise Science and Sports, University of Ferrara, 44123 Ferrara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6972-3085","authenticated-orcid":false,"given":"Natascia","family":"Rinaldo","sequence":"additional","affiliation":[{"name":"Department of Neuroscience and Rehabilitation, Faculty of Medicine, Pharmacy and Prevention, University of Ferrara, 44121 Ferrara, Italy"},{"name":"Center for Exercise Science and Sports, University of Ferrara, 44123 Ferrara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-5042-8645","authenticated-orcid":false,"given":"Federica","family":"De Luca","sequence":"additional","affiliation":[{"name":"Department of Neuroscience and Rehabilitation, Faculty of Medicine, Pharmacy and Prevention, University of Ferrara, 44121 Ferrara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5478-2499","authenticated-orcid":false,"given":"Stefania","family":"Toselli","sequence":"additional","affiliation":[{"name":"Department for Life Quality Studies, University of Bologna, 47921 Rimini, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gianni","family":"Mazzoni","sequence":"additional","affiliation":[{"name":"Department of Neuroscience and Rehabilitation, Faculty of Medicine, Pharmacy and Prevention, University of Ferrara, 44121 Ferrara, Italy"},{"name":"Center for Exercise Science and Sports, University of Ferrara, 44123 Ferrara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simona","family":"Mandini","sequence":"additional","affiliation":[{"name":"Department of Neuroscience and Rehabilitation, Faculty of Medicine, Pharmacy and Prevention, University of Ferrara, 44121 Ferrara, Italy"},{"name":"Center for Exercise Science and Sports, University of Ferrara, 44123 Ferrara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2608-8111","authenticated-orcid":false,"given":"Luciana","family":"Zaccagni","sequence":"additional","affiliation":[{"name":"Department of Neuroscience and Rehabilitation, Faculty of Medicine, Pharmacy and Prevention, University of Ferrara, 44121 Ferrara, Italy"},{"name":"Center for Exercise Science and Sports, University of Ferrara, 44123 Ferrara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,11]]},"reference":[{"key":"ref_1","unstructured":"Hosseini, S.A., and Padhy, R.K.
