The aim of Health Surveillance 2025 is to analyze and describe the state of health of students at University of Applied Science Hamburg (HAW), key influencing factors and individual resources. In areas where there is a need for action, the Health Surveillance can provide detailed insights and/or in-depth analyses. The Health Surveillance thus provides information on health-related topics and delivers scientifically sound information as a basis for health-promoting discussions in the subsequent follow-up process at various levels (e.g. faculties). In addition, the Health Surveillance 2025 at University of Applied Science Hamburg contributes to comparability with surveys at other German universities through the use of validated and standardized measuring instruments.
