Children With Intellectual Disability

Parameters of physical development are known to be informative indicators of health status and adaptation processes, as well as markers of social, hygienic and environmental well-being both in healthy children and those with various pathological conditions. The purpose of this article was to study the characteristics of the physical status of children with intellectual disabilities. Materials and methods. We examined 168 children of primary school age (7–11 years) studying in secondary schools of Krasnoyarsk. The subjects were divided into two groups: the first group included 54 children with intellectual disability (F70, F71 according to ICD-10), the second group included 114 children without intellectual disability. Anthropometric characteristics and level of physical development were studied taking into account regional centile tables. The harmony of physical development was assessed using the Quetelet index. Results. The physical development of children with intellectual disability is characterized by a lag in anthropometric characteristics compared with intellectually healthy children: body length was 133.0 and 137.3 cm (p = 0.048), head circumference 51.0 and 52.5 cm (p = 0.002) respectively. The first group also had a statistically significantly lower percentage of children with harmonious physical development (37 %, p = 0.045) against the background of pronounced disharmony (underweight in 31.5 %, excess body weight in 31.5 % of children) compared to their healthy peers (harmonious development in 55 %, underweight in 16 %, overweight in 29 % of children). Further research into the constitution of children with intellectual disability can form the basis for the development of corrective measures, taking into account the specific typological characteristics of children in this group.

Significant Difference

Lead poisoning is one of the burning issues in Bangladesh. This study assessed the relation of blood lead level with IQ and peripheral nerve function in environmental lead exposed primary school children in Dhaka.Blood lead level (BLL) was measured in 84 primary school children in an urban industrial area of Dhaka. IQ was measured with Wechsler Intelligence Scales- Revised for children. Electrophysiological evaluation was done in 31 children.Verbal, Performance and Full scale IQ had a negative correlation with blood lead level (p<0.001). Decrement in Verbal, Performance and Full scale IQ associated with 1 microgram per deciliter increase in blood lead level were 0.99, 0.86 and 0.95 respectively (p<0.001). None had clinical features of neuropathy. Statistical analysis also did not show any significant difference in NCS between children with normal and elevated BLL (p value >0.05).It was found that IQ of children decreased in a linear trend with increasing blood lead level. This study did not find any clinical or electrophysiological evidence of peripheral nerve dysfunction in the environmental lead exposed children.

The Impact

Backgrounds: About 120 million people around the world are overexposed to lead which is neurotoxic and 99 percent of the most severely affected children are in the developing world including Bangladesh. Methods and Materials: The present cross-sectional ecological study was carried out to explore the impact of lead poisoning on the intelligence level among 84 primary school children of a school of Bangladesh, aged between 8 and 14 years from September 2010 through January 2011. The research instrument was an interviewer questionnaire, questionnaire for IQ test and assessment of blood lead level (inductively-coupled plasma mass spectrometry with collision/reaction cells) of the study subjects after obtaining permission from their parents and the school authority. Results: Data were cross-checked and frequency distribution and association using chi-square test was accomplished. Background information depicted majority (69.1%) of the children aged10-11 years (mean = 10.25 ±1.177 yrs), female (51.2%), parents having primary level of education or below (73.8% in case of father and 77.4% in mother) and from lower socioeconomics (78.6% earned BDT 10,000 or below per month). Among all, majority (56%) were found to be moron, 27.4% in borderline, while 8.3% were imbecile with the same proportion with normal level. By their blood lead level. Majority (70.2%) had blood lead level up to 10 microgram/dl and the rest (29.8%) had more than 10 microgram/dl. Though no statistically significant association was found between IQ level of the children and their blood lead level (p>0.05), the health problems found among the respondents as abdominal pain (53.57%), impatience (14.29%), nausea (10.71%) and all other problems (loss of concentration to study, ear problem, anorexia and loss of weight) amounting for 21.43% are suggestive of chronic lead poisoning. Conclusion:Further studies in large scale with larger samples including comparative studies of inter-industrial areas have been strongly recommended.

The beginning of children’s school education is a potential risk of morphofunctional and psycho-physiological disorders in the body because of the significant reduction in daily physical activity, the change in day regimen, emotional and intellectual stress, which are often inadequate for the age-related psycho-physiological capabilities of schoolchildren. In this paper, we analyzed the literature on the development of modern children of primary school age according to the results of the assessment of morphological, functional and mental indicators. The identification of a general trend in the development of primary school-aged children is necessary for determination and development of health-saving programs to implement in the system of modern education. A review of data on the development of younger school children over the past 20 years shows an increase in the number of children with digressions in physical development, deterioration in physical fitness, delay of biological age from actual age, stress of the cardiovascular system, decrease in lung capacity and muscle strength. This pattern is manifested regardless of the region of residence and the nationality of children. There is an increase in the number of children with learning difficulties. Among the reasons for these changes, researchers highlight the complexity of the educational program, physical inactivity, the delay of physical development and, at the same time, medical and social successes of the state, allowing preserving the life of newborns even with somatic and neurological abnormalities. In connection with the identified trend of development of modern primary school children, the measures are needed to optimize children’s learning activities by the following criteria: level of physical activity, intensity of intellectual loads, rest mode.
