In the last decades it has been stated that the mental health of young people has deteriorated. Young persons’ report depressive feelings, anxiety and sleep-disturbance. The tendency is most pronounced for young women in the ages 16-24 years. Nowadays, the main parts of the psychiatric care are out-patient care. Family, relatives and close friends get involved and need to take great responsibility for their relative or friend with mental illness, which has consequences for their own health. This study will explore health situation among young persons’, age 16-25 years, who are identifying themselves as supporting a family member or a friend with mental illness. The collected data in this study is based on baseline data from the research project “Ps Young Support”. That research project aimed to develop and evaluate web-based health efforts for young persons’ who were close to people who suffered from mental illness. Data was collected by means of questionnaires in June 2010, which the informants (N=241, 170 females and 71 males) responded. Sociodemographic and lifestyle characteristics were obtained and self-rated health questions were asked about their general health, well-being, physical and mental illnesses. The results revealed high levels of stress, as well as different psychosomatic symptoms, such as sleeping problems, and head- or stomach ache. Over half of the young persons stated that they used some kind of non-prescriptive pharmacological treatments against pain. This is alarming and preventive health care resources should be offered to these young informal carers.
