Aims: According to surveys of parents, children adopted from abroad have more sleep difficulties than non-adopted children. Network analysis related to the sleep of children adopted to Finland have not been studied before. The aim of this study was to find out whether there are differences in the sleep indicator networks of children adopted to Finland and non-adopted children living in Finland, and which factors explain the possible differences. Methods: The research material was from the Finnish FinAdo 2 follow-up study as part of the FinAdo research project, which investigates the well-being and health of children adopted to Finland. The sample (n = 174) consists of children adopted to Finland, control children and parents. All the families who had gone through the adoption process in Finland between 2015 and 2018 were asked to participate in the study. The control data of biological children were collected from kindergartens in the Turku and Kaarina areas between 2014 and 2015. Children's sleep was measured for a week with an actigraphy (activity wristband). Parental sleep difficulties were mapped with The Jenkins Sleep Scale (JSS) and general mental symptoms with the General Health Questionnaire-12 (GHQ-12). Network analyzes were performed on children’s sleep indicators. Stepwise, logistic regression analysis was used to examine the relationships between the key sleep indicators of adopted children and the explanatory factors. Results: Adopted children slept longer and spent more time in bed than non-adopted children, their sleep was more fragmented, and the cosine peak came later. The sleep indicator networks differed in both structure and global strength between the groups. The network of adopted children was tighter, meaning that sleep indicators were more connected, and sleep was more prone to changes. The explanatory factors of the four most important sleep indicators were examined in adopted children group. Age was controlled. The amount of sleep and the fragmentation of sleep were best explained by the age, and the time spent in bed additionally the children’s gender, country of origin and health problems. In addition to the above factors, the cosine peak was best explained by the education of the adoptive mother as well as the depression and sleep difficulties of the adoptive parents.
