Etiology of mild mental retardation among Bahraini children: a community-based case control study
1Arabian Gulf University, College of Medicine and Medical Sciences, Department of Community Medicine and Human Behavior, State of Bahrain.
Insights
This study analyzed 109 Bahraini children with mild mental retardation, finding prenatal factors in 38.5%. Results challenge the idea that mild retardation is purely cultural-familial, highlighting pathological influences.
Area of Science:
- Pediatrics
- Genetics
- Public Health
Background:
- Mild mental retardation (MMR) etiology is complex, with both pathological and cultural-familial factors proposed.
- Understanding risk factors is crucial for early intervention and prevention strategies.
Purpose of the Study:
- To investigate the etiology and risk factors of mild mental retardation in Bahraini children.
- To compare predisposing factors in children with MMR to a matched control group.
Main Methods:
- Analysis of 109 Bahraini school children diagnosed with mild mental retardation, born between 1967-1982.
- Categorization of causes into prenatal, perinatal, and postnatal factors; untraceable causes were also noted.
- Comparison of background characteristics (e.g., parental literacy, consanguinity) with a control group from community schools.
Main Results:
- Identified prenatal causes in 38.5%, perinatal in 11.9%, and postnatal in 7.4%; 42% had untraceable causes.
- Significantly higher prevalence of illiterate fathers, consanguinity, and a family history of mental retardation in the MMR group.
- These findings indicate a stronger pathological influence than suggested by cultural-familial theories.
Conclusions:
- Mild mental retardation in this cohort has significant pathological underpinnings.
- Consanguinity and parental illiteracy are notable risk factors associated with MMR in the studied population.
- Results necessitate a re-evaluation of the predominantly cultural-familial model for mild mental retardation.
Abstract:
The etiology of and suspected risk factors leading to mild mental retardation were analyzed in unselected series of 109 Bahraini school children with this condition born between 1967 and 1982. The cause was considered to be prenatal in 38.5% of the children; perinatal (asphyxia and prematurity), in 11.9%; and postnatal, in 7.4%. In 42% the cause was untraceable. Predisposing background factors associated with mild mental retardation were compared with characteristics of a matched control group from community schools. An illiterate father, consanguinity, and a relative with mental retardation were significantly more common among the sample with mild mental retardation. These results are not consistent with the view that mild retardation is predominantly cultural-familial and not pathological in nature.
