Environmental factors and psychomotor development in children up to the age of 3

Abstract

Abstract Introduction Chemical compounds and other pollutants found in the environment have a well-documented, adverse effect on the life and health of individuals. Those who are most vulnerable to toxic effects include prospective parents, pregnant women, foetuses, and young children. In Poland, both the prevention and early detection of developmental abnormalities is insufficient. The objective of the study was to analyse how the pre- and postnatal development of a child is affected by toxicants the mother has been exposed to. Materials and methods The study was conducted in the form of a diagnostic survey. The degree of toxic exposure was assessed based on Wawrzynów’s questionnaire, the Mothers’ Toxic Exposure Assessment Questionnaire’ (Kwestionariusz Oceny Narażenia Matek Dzieci na Toksyny – KONT-15). The evaluation of child development was based on the following psychometric tools: the Munich Functional Developmental Diagnostics (MFDD), the Speech (MM-speech) and Reflex (MM-reflexes) Development Questionnaire, IRMIK (Inwentarz Rozwoju Mowy i Komunikacji) – the Polish adaptation of the MacArthur-Bates Communication Development Inventories (CDI), and the Child Development (RD-18) questionnaire, also designed by Wawrzynów. Results The study included 102 mothers of children up to 3 years of age. Most of the surveyed mothers indicated large urban agglomerations with more than 100,000 inhabitants as their current place of residence. The study demonstrated that a substantial majority of the mothers had come into contact with toxicants. A statistically significant relationship was demonstrated between developmental delays in children and high exposure to toxins in mothers. There was no statistically significant relationship between maternal exposure to toxins and delays in the development of speech and reflexes. Conclusions Environmental pollutants found primarily in air, food, medication, and everyday items, exert a negative influence on childhood development. A high maternal exposure to toxins contributes to developmental delays in speech and reflexes in children. Delays in speech and communication development were observed more frequently in children who were older. Developmental delays in children were more common among younger children.
