The aim of this research is to determine the development trend of morphological characteristics of children in the year before starting school. The research included a sample of 72 children aged 76 to 93 months (AS ± SD = 83.51 ± 3.90). The sample of respondents includes 41 girls and 31 boys whose data were collected from the Rijeka Kindergarten, more precisely from the Zamet Preschool Education Center. The sample of variables consists of morphological measures: body height, body mass and body mass index. The results of the research showed that with the increase in chronological age, an upward trend of growth in body height and body mass was observed, while a downward trend was observed in the body mass index. Furthermore, children of pre-school age have average values when compared to the standard values of the World Health Organization. A greater dispersion of the sample was also observed in the body height variable compared to the last two observed variables. This research work enriches the existing literature that deals with the morphological status of children before starting school, it can help determine the key parameters for assessing the morphological status that could be applied in future work and indicates the current state of the morphological status, which enables analysis in the form of further practical actions.
