Assessment of students’ health status using the George Rasch measurement model

Introduction. In the context of total digitalization of various spheres of human life, the problem of health in student youth is given increased attention. Therefore, the topic we have chosen is quite relevant.

Materials and methods. To obtain primary data, more than four hundred fifty Omsk 18-20 years students were tested in 2020 and 2025. The processing and analysis of the obtained dichotomous data were carried out using the George Rasch measurement model, which is a visual display of the results of observations of the importance of the studied latent property of a person and the complexity of test elements on a general logarithmic scale.

Purpose. Determination of the indicators of the student’s «health level» and the «significance» of test questions using the George Rasch measurement model.

Results. A comparison of these indicators revealed that students in 2025 are more likely to take medications without a doctor’s prescription than those in 2020. The number of colds among students has remained virtually unchanged, and meals have become more regular, though proper lunches are often replaced by fast food. The number of students participating in sports has increased, but the number of students with unhealthy habits has remained the same. The number of students in «very close to good» health in 2025 has increased significantly compared to 2020.

Research limitations. The survey is limited to a survey of Omsk students.

Conclusion. The obtained results can be used by administrative structures in the field of youth policy in the region to make management decisions to improve the health of students.

Compliance with ethical standards. The study was approved by the local ethics committee of the Federal State Budgetary Educational Institution of Higher Education «Omsk State Medical University of the Ministry of Health of the Russian Federation», protocol dated January 20, 2025.
