This review presents the relationship between serious life events, chronic family difficulties and illness, and focuses on how healthy children cope. Hospitalised children had experienced about twice as many serious life events as children in healthy environments. Known diseases related to stress are eczema, upper respiratory tract infections, asthma, ulcerative colitis, heart disease in adults, juvenile rheumatoid arthritis, fibromyalgia and juvenile diabetes. Research on healthy children at risk (resiliences) has revealed a number of social and interpersonal protective factors. A modified biopsychosocial model, for the purpose of understanding the health status and care of children at high risk, is presented. More research is needed to understand these multietiological diseases in order to develop strategies for the promotion of good health.
