RT journal article T1 Young adult stage: Exploring clustered behaviours and their impact on the health of university students A1 Palma Leal, Ximena A1 López Gil, José Francisco A1 Rodríguez Rodríguez, Fernando A1 Camiletti Moirón, Daniel A1 Chillón, Palma A2 Didáctica de la Educación FísicaPlástica y Musical K1 College students K1 Health promotion K1 Public health K1 Transitions K1 Development AB The transition to university life frequently entails significant lifestyle changes, including increased independence,academic pressure, and social demands, which can lead to the adoption of unhealthy behaviours and a decline inoverall well-being. The purposes of this study are to identify different lifestyle behaviour patterns in Chilean andSpanish university students according to their sleep duration, breakfast status, physical activity levels, sittingtime and mode of commuting, and to determine their association with fitness components. A total of 2269university students (52.9 % women), with an average age of 26.8 ± 6.0 years old, participated in this study.Reliable self-report questionnaires were used to measure different lifestyle behaviours patterns and physicalfitness components. A two-step cluster analysis was performed to examine the different lifestyle behaviourpatterns. Logistic regression models were used to determine the associations. Three different lifestyle patternswere identified. Students in Cluster 2 and 3 were more likely to report higher cardiorespiratory fitness (odds ratio[OR]: 1.35, p = 0.015; OR: 1.37; p = 0.038, respectively) and muscular strength (only significant for Cluster 2,OR: 1.29; p = 0.038) than students in Cluster 1. Considering the unique challenges and lifestyle adjustmentsassociated with university life, the finding of this study could be clinically relevant and have important implications for future practice oriented to the public health and adult population, as both components of physicalfitness are powerful markers of physical, psychological, and social well-being in this population.
