 The study found four distinct clusters of health behaviors among Swedish adolescents, depending on gender and age. The first cluster consisted of mixed eating behaviors and habits, physical activity, and low levels of alcohol consumption. The second cluster consisted of healthy lifestyle behaviors. The third cluster consisted of unhealthy lifestyle behaviors. Finally, the fourth cluster consisted of breakfast, low levels of alcohol consumption, and tobacco use. Socioeconomic factors such as socioeconomic disadvantage, having a migrant background, and living in reconstituted families or single-parent households were strongly associated with unhealthy behaviors.
