The growing trend of health problems related to spinal deformity calls into question the quality of the modern lifestyle, especially among young people. Globalization and digitalization, which have become key determinants of modern society, have significantly contributed to a sedentary lifestyle. This way of life, which is often spent sitting in front of a computer or smart devices, has a negative effect on body posture and the position of the spine, often from an early age. Consequently, postural and spinal deformities are becoming increasingly common. The aim of this paper is to analyze the physical activities and life habits of students as well as the presence of kyphosis deformation. The research was conducted using an online questionnaire and the DIERS Formetric 3D/4D device on a sample of eighteen (N = 18) healthy students studying Physiotherapy at the University North in Varaždin. The results of the research indicate a high presence of kyphosis in young people (39 % of participants), 67 % of whom engage in physical activity and recreational sports. The obtained results indicate that kyphosis and kyphotic bad posture are mostly attributed to bad lifestyle habits and a sedentary lifestyle. Physiotherapists also play an important role in the treatment of kyphosis, who must properly assess the condition during the physiotherapy assessment, as well as the presence of impairments or limitations that the individual is facing. The paper further details the anatomy of the spine, its function and spinal deformities with an emphasis on kyphosis and poor kyphotic posture. The procedure of physiotherapy assessment and physiotherapy intervention as well as the results of the conducted research are also described.
