Background: There are hardly any prevention programmes for health education and communication for boys in Germany. Boys seldom know when, how and to whom to turn to for questions or problems in the field of sexual and reproductive health.
Methods: From 2014-2016 the Medical Society for Health Promotion carried out a unique project for gender-sensitive medical health promotion for boys of all school types at 130 Bavarian schools. In 2015, 15 Bavarian schools took part in the evaluation (6th, 8th, 9th and 11th grade). At school level, similar schools have been randomised to trial and control groups. In the experimental group, three waves were conducted in panel design and two interviews were conducted in the control group using paper questionnaires. The number of cases in the panel is 599 (358 intervention group, 241 waiting control group).
Results: In all school types and grade levels, a highly significant increase in knowledge can be demonstrated. There is an average of 28% of the intervention group's overall knowledge improvement compared to the control group. More than 50% of the participants consider themselves to be very well informed before the intervention, although the objectively available knowledge does not justify this (e. g. average proportion of correctly answered questions on male anatomy and physiology 0.7 out of 6). The participants rate the medical information sessions and the fact that they are conducted by doctors with 1.7 or 1.6 (1: very good, to 5: poor).
Discussion: Boys urgently need proper knowledge transfer in the field of sexual health. They benefit regardless of the types of school from these health information sessions. The gender-sensitive and socially compensatory medical information sessions are highly accepted, effective and serve as a bridge to the general practitioners. A nationwide establishment of the intervention seems thus absolutely necessary.
