The study included 380 female students and 211 male students aged 20.7\u2009\u00b1\u20091.5 years. The ThKA and LLA were measured using a Plurimeter-V gravity inclinometer. The level of PA was estimated using the International Physical Activity Questionnaire. ThKA was lower in women compared to men, while LLA was higher in women than in men (p\u2009&lt;\u20090.0001). Female students reported lower PA than male students (p\u2009&lt;\u20090.001). Female students with ThKA within normal values reported a significantly higher amount of low-intensity PA compared to those with ThKA below or above the norm. A correlation was found between ThKA and body mass index (BMI), body adiposity index (BAI), WC, and fat percentage (rho\u2009&lt;\u20090.2), whereas LLA showed correlations with BMI, BAI, waist circumference, and fat percentage (rho\u2009&lt;\u20090.2). Among male students, a correlation was found between LLA and BMI as well as WC (rho\u2009&lt;\u20090.2). Maintaining a healthy body composition may be instrumental in mitigating the risk of developing spinal curvature abnormalities.<\/jats:p>","DOI":"10.1038\/s41598-024-62929-9","type":"journal-article","created":{"date-parts":[[2024,5,28]],"date-time":"2024-05-28T20:38:10Z","timestamp":1716928690000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Sagittal spinal curvatures of young adults in the context of their self-reported physical activity and somatic parameters"],"prefix":"10.1038","volume":"14","author":[{"given":"Ma\u0142gorzata","family":"Grabara","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Witkowska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,5,28]]},"reference":[{"key":"62929_CR1","doi-asserted-by":"publisher","first-page":"2373","DOI":"10.1016\/j.spinee.2014.01.040","volume":"14","author":"F Ara\u00fajo","year":"2014","unstructured":"Ara\u00fajo, F., Lucas, R., Alegrete, N., Azevedo, A. & Barros, H.
