Background: A posture defect may be defined as a syndrome of abnormalities occurring in a relaxed upright position of the body. Deviations from the typical body shape are specific for given age and gender. Life determinants and social situation have a very significant impact on the development of body posture in young people. Aim of the study: The aim of the study was to analyse the occurrence of spinal defects in children aged 3–6 years. Material and methods: The study included 75 children aged 3–6 years. The children were examined for spinal defects using the MORA computer system. Results: Boys in the study showed a correlation between height and the inclination of the upper thoracic segment, whereas no such correlation was observed in girls. A significant relationship was also demonstrated between BMI and compensation and inclination of the lumbar segment in all subjects. Overall height was also noted to be significantly related to both spine length and the length of its curvature. Conclusions: The occurrence of spinal defects is influenced by gender. BMI can have a significant impact on spinal morphology and the formation of body posture, even in pre-school age children.
