Summary
A life-course perspective is according to the World Health Organization about increasing the effectiveness of health promotion interventions at all ages. This targets the needs of human beings throughout their life. Descriptions of the phenomenon of the inner child invite the possibility that it may be of help when promoting health throughout the life-course. The aim was to describe and understand schoolchildren’s, adults and older person’s experiences of childhood in connection to health and well-being in the present and through the life-course, illuminating the inner child. The research strategy used was a secondary analysis of the original transcribed data from three Swedish studies investigating new questions. In total, 53 individuals aged 9–91, 20 school children, 20 adults and 13 older persons were interviewed about childhood experiences. The schoolchildren were invited to create a drawing, and to narrate about it during the interview. The main question in the secondary analysis was ‘How do the participants’ narrations about childhood experiences illuminate the inner child, useful for health promotion through the life-course?’ The findings showed the importance of a secure atmosphere and trusting relationships, indicating that experiences during childhood can help us to adapt and pass along life lessons across generations. There were narratives about play as an activity where they learned to promote a healthy childhood, struggle for independence and learning how to be responsible when growing up. Dimensions of mental, social and existential well-being can be seen as examples of the inner child’s role in health promotion through the life-course.
