Socio-Economic Status May Associate Different Risk(s) with Early Childhood Caries (ECC) That Can Cause the Development of Psychomotor Deficiency in Preschool Children Aged 3-6 Years Old: The Results of Preliminary Analysis from a Cohort Study

Int J Environ Res Public Health. 2021 Aug 26;18(17):9011. doi: 10.3390/ijerph18179011.

Abstract

Background: We have recently shown that there is a positive correlation between severe caries and developing psychomotor deficiency in preschool children. To fully re-assess such a relationship, we embarked on a 3-year longitudinal follow-up study of kindergarteners, where we aimed to: (i) confirm whether early childhood caries is causally related to the development of psychomotor deficiency as proposed, and (ii) address any significant role or contribution of socio-economic status associated with caries-psychomotor interactions in the preschooler family cohorts studied, over time.

Methods: A longitudinal study was designed where the total sum of 159 kindergarteners aged 3-6 from the central and southern regions of Taiwan were randomly selected and recruited for clinical examination of caries, together with questionnaires for personal, demographic and dietary information, socio-economic status, and the children's psychomotor development scales which were collected and analyzed over time. Student's t test, chi-squared test, correlation coefficients, and multiple linear regression analysis with R2 determinants were employed to assess any attributable differences (of 0~1) between SES vs. psychomotor manifests and caries measured among all variables computed.

Results: The results of our preliminary analyses show that: (i) there was likely a causal relationship between caries activities and aspects of general development scale via the Chinese Child Development Inventory over time (4.01 ± 3.47 vs. 5.88 ± 2.58, respectively) in the 3-6-year-old preschoolers, and (ii) there was significantly more attributable influence (via higher R-squared values) from SES and psychomotor manifests than that of caries and the Chinese Child Development Inventory counterparts, as detected over time.

Conclusion: Collectively, the resulting analyses support our previous findings and confirm that there is likely a causal relationship between severe caries and psychomotor deficiency in growing preschoolers; the resulting analyses revealed that such causally related interactions may be attributably explainable by a content-reliant association via socio-economic status analyzed in the kindergartener family cohorts studied. Thus, the socio-economic status or its constituents/factors will have a much broader influence not only associated with developing early childhood caries (a biologic trait), but also for psychomotor deficiency (a social trait) in vulnerable children at risk.
