Objective: Toexploretheclusteringofdifferentlifestylebehaviorsandwhetherthisclusteringdiffersby gender, age, and health-related fitness. Design: Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) cross-sectional study. Setting: Ten European cities. Participants: A total of 2,084 adolescents (12.5–17.5 years). Main Outcome Measures: Four lifestyle behaviors were assessed by self-administered questionnaires: moderate to vigorous physical activity, homework time, screen time, and diet. Health-related fitness com- ponents (aerobic capacity, strength, speed-agility, and body composition) were assessed. Analysis: Hierarchical method and k-means cluster analysis. Analysis of variance tests. Results: Five clusters were identified: Healthy diet and Active, Healthy diet and Academic, Healthy diet and Inactive, Unhealthy diet and Screen user, and Unhealthy diet and Active. Younger adolescents were more active and followed a healthier diet than older adolescents. Older boys devoted more time to screen use, whereas older girls devoted more time to homework. Boys in the Healthy diet and Active cluster pre- sented higher aerobic capacity and speed-agility, whereas girls presented higher aerobic capacity, strength, and speed-agility. ConclusionsandImplications: Clusteringofdifferentlifestylebehaviorsisobserved.Differenthealthy lifestyles do not always come together and clusters are associated with gender, age, and health-related fit- ness, but not with body composition. These differences need to be considered when developing interven- tion strategies for the prevention of unhealthy habits.
