Introduction: According to the data of epidemiological studies, the prevalence of IDA, even within the same country, is not the same, and largely depends on the ecological, industrial, climatic and geographical conditions of residence. The most vulnerable contingent for the development of IDA includes adolescent children, especially women. Objective: The main task of this article was to study the influence of growth factors in girls aged 12-14 years on the formation of iron deficiency anaemias, to determine ways to optimize their diagnosis. Methods: The intensity of the increase in length and body weight of girls, depending on the age and severity of ID is estimated. Also we measured, indicators of length and body weight of girls depending on the severity of iron deficiency and age. Result: However, not all factors causing IDA at this age are equal. Judging by the literature data, the influence of growth factors on the ferrostatus of adolescents has been studied most poorly. Some authors believe that IDA negatively affects the anthropometry indicators of schoolchildren, increasing among them retarded (lagging) in physical and sexual development, while others indicate that increased growth and development are __ampersandsignldquo;guilty__ampersandsignrdquo; of the manifestation of IDA, from - for the aggravation of the severity of latent iron deficiency __ampersandsignndash; LID. Conclusion: Solving these issues would make it possible to concretize the methods of dispensary observation of adolescents with iron deficiency and develop more effective methods of prevention and therapy for the haemoglobin recovery of schoolchildren with IDA in its early stages.
