The role of social, demographic and territorial factors in the late detection of hip dysplasia in children in the Republic of Kazakhstan

Abstract

BackgroundThe aim of this research is to identify and study the role of social, demographic and territorial factors in the late detection of children with hip dysplasia.MethodsWe conducted a retrospective cohort study of epidemiological data of patients treated in a hospital in the department of orthopedics of the unitary enterprise based on the right of "Multidisciplinary children's municipal hospital No.2" Nur-Sultan (Kazakhstan) in the period from September 2019 to February 2021. The analysis of archival case histories of 309 patients was carried out. There were 214 early and 95 late detections of this disease. Late detection of hip dysplasia was significantly more likely at birth in cranial presentation (81%, p <0.004).ResultsTwo-dimensional analysis also showed that late detection was more likely in patients from rural areas (228 children, 73.8%, p < 0.001), and that (26 children, 11.4%, p = 0.005) these were children from regions with lower income (42500 tenge per month, p<0.001). There were also significant differences (p = 0.015) in the early (214 children, 69.26%) and late (95 children, 30.7%) diagnosis of hip dysplasia among children whose parents used a national cradle with tight swaddling (95% CI: 1.16 – 4.49).ConclusionsIn our study, we found that children from rural regions of the Republic of Kazakhstan, indigenous Kazakh nationality, using the national cradle in their everyday life, as well as from regions with low average incomes, were significantly more likely to be exposed to late detection of hip dysplasia.
