The aim of this study was to investigate how 6th graders’ self-rated health, physical activity and sleep disruptions are related to schoolwork engagement. In more detail it was examined what kind of groups 6th graders can be divided into according to self-rated health, physical activity and sleep disruptions. Furthermore, it was studied if these groups are differently related to sex, sleep duration, the quality of sleep and schoolwork engagement. The aim is to gain better understanding about the factors which might have a strengthening effect on the adolescents' schoolwork engagement. The data was collected by the Mind the Gap –project in Helsinki in the spring 2013. The 6th graders (N = 761) from 33 different schools answered a questionnaire. The variables that were used for this study measured adolescents’ self-reported schoolwork engagement, health, physical activity, sleep disruptions, the quality of sleep and sleep duration. K-means cluster analysis was used to sort ado-lescents to groups by the variables of self-rated health, physical activity and sleep disruptions. When interpreting the contents of groups, an analysis of variance was used. The differences of these formed groups with sex, sleep duration, the quality of sleep and schoolwork engagement were ex-amined with the cross tabulation, analysis of variance and Kruskal-Wallis test. The 6th graders were divided into four groups regarding experienced health, physical activity and sleep disruptions. These groups were named healthy movers, movers with sleep and health prob-lems, non-movers with sleep problems and non-movers with health problems. In the group of healthy movers adolescents was slept longer and had more schoolwork engagement than in the other groups. In the groups of healthy movers and non-movers with health problems had better qual-ity of sleep than in two groups in which sleep disruptions were experienced. The self-rated health, the physical activity and the paucity of sleep difficulties together were connected to sufficient sleep duration and schoolwork engagement.
