During this developmental phase, daily habits such as prolonged sitting, sedentary behaviors and the adoption of non-neutral postures may contribute to spinal overload and pain symptoms. This study contributes to the existing literature by focusing on concrete postural behaviors in real-life daily situations, an aspect that is still underexplored despite its relevance for musculoskeletal health. The aim of this study was to investigate the associations between daily habits, postural behaviors and the presence of back and neck pain. Methods: A cross-sectional study was conducted on a sample of 70 adolescents aged 10\u201320 years. Data were collected using the Back Pain and Body Posture Evaluation Instrument for Children and Adolescents (BackPEI-CA), administered online. Descriptive statistics and chi-square tests with effect sizes (Cramer\u2019s V) were used to examine associations between postural behaviors, lifestyle factors, and pain outcomes, providing an inferential assessment beyond simple descriptive analysis. Results: Significant associations were found between gender and back pain, sitting posture during daily activities (writing at the desk and talking with friends) and back pain, with flexed or asymmetrical postures more frequently reported among participants with pain, and between back and neck pain (p &lt; 0.05). Conclusions: The findings highlight the relevance of gender and daily postural behaviors as factors associated with musculoskeletal pain in adolescents. By identifying posture-specific behaviors linked to pain, this study provides preliminary evidence that can inform targeted preventive strategies and guide future research on modifiable daily habits in youth.<\/jats:p>","DOI":"10.3390\/children13050698","type":"journal-article","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T16:46:18Z","timestamp":1779381978000},"page":"698","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Physical Development and Postural Behaviors in Children and Adolescents: A Cross-Sectional Study"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1441-8101","authenticated-orcid":false,"given":"Francesca","family":"D\u2019Elia","sequence":"first","affiliation":[{"name":"Department of Human, Philosophical and Education Sciences, University of Salerno, 84084 Fisciano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5656-7490","authenticated-orcid":false,"given":"Rosario","family":"Ceruso","sequence":"additional","affiliation":[{"name":"Research Centre for Physical Education and Exercise, Pegaso Telematic University, 80143 Naples, Italy"},{"name":"Department of Neuroscience, Biomedicine and Movement, University of Verona, 37129 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Giardullo","sequence":"additional","affiliation":[{"name":"Research Centre for Physical Education and Exercise, Pegaso Telematic University, 80143 Naples, Italy"},{"name":"Department of Neuroscience, Biomedicine and Movement, University of Verona, 37129 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelica Delfina","family":"Picone","sequence":"additional","affiliation":[{"name":"Department of Human, Philosophical and Education Sciences, University of Salerno, 84084 Fisciano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5124-2446","authenticated-orcid":false,"given":"Vera","family":"Simoes","sequence":"additional","affiliation":[{"name":"School of Sport Rio Maior (ESDRM), Santar\u00e9m Polytechnic University\u2014Santar\u00e9m & Rio Maior, 2001-904 Santar\u00e9m, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiziana","family":"D\u2019Isanto","sequence":"additional","affiliation":[{"name":"Research Centre for Physical Education and Exercise, Pegaso Telematic University, 80143 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3659-8943","authenticated-orcid":false,"given":"Giovanni","family":"Esposito","sequence":"additional","affiliation":[{"name":"Research Centre for Physical Education and Exercise, Pegaso Telematic University, 80143 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Dop, D., P\u0103dureanu, V., P\u0103dureanu, R., Niculescu, S.-A., Dr\u0103goescu, A.N., Moro\u0219anu, A., Mateescu, D., Niculescu, C.E., and Marcu, I.R.
