Prevalence and Significance of Minor Anomalies in Children With Impaired Development

The study examined the hypothesis that the prevalence of Waldrop's minor physical anomalies in children with developmental disorders (DD) (mentally retarded - MR, with impaired hearing - IH and impaired vision - IV) is higher in relation to a control group of healthy schoolchildren (HS). Methods: The study was carried out on a sample of 469 children ; 223 children with DD (109 MR, 64 IH, 50 IV) and 246 healthy schoolchildren. Those children with recognizable genetic syndromes were excluded from the study. Results: The examined groups of subjects with DD and HS significantly differed according to the number of minor anomalies and also their weighted scores according to Waldrop. Multivariate discrimination analysis with two discriminational functions explained as many as 96.51% of the total variability, significantly distinguishing the HS group from the DD group. However, it was not possible to achieve clear distinction between MR and IV. The interrelation of the number and sum of the weighted scores of minor anomalies according to Waldrop show similar minor anomalies in the MM group (mean per person 3.65 and 3.82 respectively) and the IV group (mean per person 3.24 and 3.50 respectively) and in the IH group (mean per person 3.84 and 3.67 respectively) and the HS group (mean per person 1.70 and 1.46 respectively) although at different levels. Conclusions: The significantly higher number of minor anomalies and their weighted score according to Waldrop in all three groups of children with DD compared to healthy children, suggest that during early development the factor which is the cause of a specific developmental disorder (handicap) and the occurrence of a minor anomaly, have a joint effect.
