This publication includes opinion and research papers written by authors with academic backgrounds from the Czech Republic, Slovakia and Poland. The monograph consists of 14 chapters and the order of them refers to the relationship between the family and the health of its members. The first seven texts concern children’s health problems. The next two concern widely defined issues of nutrition and adult nursing. The next four discuss health issues of the elderly, while the last describes the dilemma of bereaved family members who have to decide about organ donation. The individual chapters show different aspects of family participation in the treatment and care of children, the elderly, the chronically ill, and the disabled. The discussed topics are a part of the wider issue of social medicine. A very important issue is the interdisciplinary problem of interaction between health and illness and their influence on the family, which is on one hand embedded in medical science, while on the other hand it refers to the social sciences, especially family sociology, psychology, pedagogy, and also social policy to some extent. The authors of the monograph also discuss the issue of life quality of the elderly living in domestic environments and the health and social problems they face. The authors also analyse the role of nurses in promoting health, such as immunisation, rational nutrition, and ethical aspects such as the screening of newborns. This monograph is addressed to all who work or want to work with families and support them in the difficult challenges posed by disease. The authors hope the monograph will increase understanding and familiarity with the health problems of relatives.
