Psychiatric hospitalization is indicated for children and adolescents who are in acute danger of doing harm to themselves. Specific types of treatment, family-centered methods in particular, have been found to lessen the frequency of suicidal ideation and suicide attempts. The administration of antidepressant drugs to children and adolescents is controversial, as there is evidence of increased suicidality (but not mortality) for single medications. Antidepressant drugs should not, however, be withheld for this reason, if indicated. The prerequisite in all cases is close observation. Conclusion To prevent suicide and improve outcomes, risk factors for suicide must be considered, and the indications for primary and secondary preventive and therapeutic measures must be established. Online therapeutic modalities may become more widely used in the near future, particularly among young patients, who are well versed in the use of the Internet.Background Overweight and obesity are an increasingly serious public health problem in Western societies, including Germany. The tendency of overweight and obese people not to classify themselves as such limits the efficacy of information on the health risks of these conditions and lessens the motivation to change behavior accordingly. In this article, we summarize the available study data on the selfperception of weight class. We present and discuss the differences between selfreported body-mass index (BMI) category and the actual category of the BMI when it is calculated from the individual's measured height and weight. Methods We systematically searched the Medline, EMBASE, and Cochrane Library databases in August 2017 for pertinent publications. The study protocol was published in the PROSPERO register (CRD42017064230). Meta-analyses were calculable for a number of subgroup analyses. Results A total of 50 studies from 25 countries we
