Anthropometric asymmetry in normal and mentally retarded males. 1984

R M Malina, and P H Buschang

Anthropometric asymmetry was considered in a sample of 202 normal and about 200 mentally retarded males. In addition to height, 11 bilateral measurements of bone, soft tissue and strength were taken. Differences between bilateral measurements were analysed in terms of absolute and signed differences, and in terms of the differences corrected for height. Mentally retarded individuals show greater anthropometric asymmetry than normal individuals in both absolute measurements and those corrected for height. The distributions of the differences, both absolute and signed, are also broader in the retarded, and variances of the left-right differences are greater than variances associated with measurement. Left-right differences between the normal and retarded males occur primarily in the upper extremity; in contrast, side differences in the lower extremity are not great. Within the mentally retarded sample, there are no significant left-right differences among different I.Q. groups. However, there are significant differences among aetiological categories, and those with neurological impairment are more structurally asymmetrical.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008607	Intellectual Disability	Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range. Scores below 67 are in the disabled range.

D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.

D000886	Anthropometry	The technique that deals with the measurement of the size, weight, and proportions of the human or other primate body.
D012885	Skinfold Thickness	The measurement of subcutaneous fat located directly beneath the skin by grasping a fold of skin and subcutaneous fat between the thumb and forefinger and pulling it away from the underlying muscle tissue. The thickness of the double layer of skin and subcutaneous tissue is then read with a caliper. The five most frequently measured sites are the upper arm, below the scapula, above the hip bone, the abdomen, and the thigh. Its application is the determination of relative fatness, of changes in physical conditioning programs, and of the percentage of body fat in desirable body weight.
