Assessment of linear growth of children with cerebral palsy: use of alternative measures to height or length.

Various linear measurements were made of 100 children with cerebral palsy to evaluate the effects of various factors on growth, and to investigate the use of alternative measurements to height or recumbent length. Linear growth was more retarded in children with spastic quadriplegia than in those with less widespread spasticity, and there was a tendency for the older children to be more growth-retarded. Upper-arm and lower-leg lengths provided useful information about linear growth. Growth charts using these alternative measurements have been developed which can be used to assess linear growth of children with cerebral palsy when it is difficult or impossible to measure height or recumbent length because of joint contractures. These charts should improve the assessment of the nutritional status of children with cerebral palsy.

Anthropometry

Assessment of overweight children with trisomy 21.

Mean weights for 5-cm stature intervals for three groups of children with trisomy 21 were compared with those for a group of nonretarded children. Children with trisomy 21 had statistically significant larger mean weights beginning at statures of 105 to 110 cm for boys and at 95 to 100 cm for girls and at most larger statures analyzed. These statures were typical of 4- to 6-year-old children with trisomy 21. Children with trisomy 21 living in institutions tended to have larger mean weights for each stature interval than did those reared at home. Differences between the trisomy 21 and nonretarded groups were greater for girls than for boys.

Adolescent

Growth of children with Down's syndrome: birth to age 3 years.

A sample of 90 children with Down's syndrome were measured for recumbent length and weight from birth to age 36 months at the Children's Hospital Medical Center in Boston. At birth, means for both length and weight were reduced by about 0.5 SDs from the control group means. By 36 months, mean recumbent length was greater than 2 SDs below that for the control group, while the mean for weight was reduced by about 1.5 SDs from the control group mean. Growth velocity for both length and weight was most deficient within the first two years of life. About 30% of the sample demonstrated excess weight for length relations by 36 months. Children with moderate or severe heart disease were significantly smaller than those without or with mild cardiac problems at all times after birth. Measurements of a subsample of children at 4, 5, and 6 years of age suggested that growth velocity after 3 years of age may be within the range of normal. Assessment of growth of the child with Down's syndrome may be carried out with reference to charts plotting tenth to 90th percentiles based on these data.

Fat distribution in children with cerebral palsy.

Triceps and subscapular skinfolds were measured on 95 North American children with cerebral palsy. Triceps fat was far more depleted than subscapular fat in comparison with population standards for sex, age and race. This truncal distribution of fat may be related to the high prevalence of under nutrition found in the sample.
