Living with Juvenile Idiopathic Arthritis from childhood to adult life. An 18 year follow-up study from the perspective of young adults

Background and aim: As an experienced paediatric nurse I have recognised that adolescents with persistent chronic childhood diseases fall between two chairs. International studies support this recognition. Norwegian adolescents with juvenile idiopathic arthritis are no exception. Chronic arthritis from childhood might have far-reaching consequences for the growth and development of the child, and for the family and community. The fact that a considerable proportion of children with JIA continue to have active disease and disease residua through adolescence into adulthood underlines the importance of illuminating the situation in a public-health perspective. Through this study I aim at exploring physical and psychosocial health among young adults with JIA in a life-span perspective from childhood and adolescence into adult life. Methods: The thesis has a qualitative and a quantitative approach. Study I had an abductive explorative design. The experiences and perceptions of health-care transition were explored by focus-group interviews with young people with JIA and related health professionals respectively. Qualitative content analysis was utilised. Study II had an abductive explorative design with qualitative interviews to explore young adults’ experiences of living with JIA in a life-span perspective. Qualitative content analysis was utilised. Study III had a longitudinal deductive design. The standardised questionnaires of Health Assessment Questionnaire, General Health Questionnaire version 30, and Visual Analogue Scales of pain, fatigue, and illness were utilised to explore physical ability, psychosocial health, pain, fatigue, and illness in a cohort of patients with JIA 18.3 years after symptom-onset. Comparisons with baseline and first follow-up were performed. Data were analysed by descriptive statistics and non parametric tests. Study IV had a cross-sectional deductive design. In addition to the questionnaires utilised in study III, the questionnaire of SF-36 Health Survey and data on education, employment, need of assistive equipment at work, and use of health services the previous year were employed. Comparisons with Norwegian populationbased data were performed. Data were analysed by descriptive statistics, and parametric and non parametric tests. Findings: In study I, ability to live a meaningful and responsible adult life seemed to be a common goal. Obstacles for the young people were the nature of the disease, a lack of focus on transition processes, and overprotective parents and health professionals. Obstacles for the health professionals were lack of inter-professional and inter-institutional formal cooperation and agreed practice, and lack of competence on adolescent development and health. Study II demonstrates that living with JIA implies a constant oscillation between struggle and adjustment to an insecure everyday life and an unpredictable life course. This was expressed as bodily experiences of limitation and freedom, interpersonal experiences of being included or set on the sidelines, and intrapersonal perceptions of insecurity and confidence. Of the 55 young adults with JIA in study III, 21 reported physical disability, and 12 reported psychiatric distress within the clinical range. Furthermore, 26 patients reported illness, 27 pain, and 33 fatigue above 10 on the VAS scale (0-100). Significant correlations were found between physical disability, pain, illness and fatigue, and between psychiatric distress, pain, and fatigue. Comparisons from first to second follow-up of the cohort showed no significant changes in physical or psychosocial functioning, pain, or fatigue. In study IV, physical ability and pain were significant predictors of the average variation of physical health while psychiatric distress and female gender were significant predictors of the average variation of mental health. Impaired physical health was associated with low rates of psychiatric distress. As compared to the general Norwegian population, impaired HRQL in the physical domain was found, but not in the mental domain, and a higher level of education, but similar employment rate. Conclusion: The four studies demonstrate complementary findings. Discrepancies between interviews and inquiries indicate that the interviews illuminate a depth and breadth of life with JIA in a life-span perspective that not is possible to unveil solely by standardised inquiries. Although persistent favourable outcomes are found physically and psychosocially from first to second follow-up, young adults with JIA reveal that life with JIA encompasses struggle and adjustment to an insecure life situation physically, psychologically, and socially.
