Measurement of growth in children with renal insufficiency
Insights
Serial measurements of growth indices like stature and weight are recommended for children with kidney disease. Standard deviation scores are useful for comparing stature between groups or over time.
Area of Science:
- Pediatric Nephrology
- Growth and Development Assessment
Background:
- Assessing growth in children with kidney disease is crucial for monitoring health and treatment efficacy.
- Established methods for individual growth assessment exist, but group comparisons require further development.
Purpose of the Study:
- To recommend suitable indices for assessing growth in pediatric kidney disease patients.
- To outline methods for evaluating individual growth and comparing growth rates in groups.
Main Methods:
- Serial measurements of stature, weight, skinfold thickness, arm circumference, skeletal maturity, and sexual development.
- Relating stature to bone age for growth potential evaluation.
- Utilizing standard deviation scores for comparing stature between groups or over time.
Main Results:
- Recommended indices provide a comprehensive assessment of growth in pediatric kidney disease.
- Standard deviation scores offer a statistically sound method for comparing stature.
- Weight, skinfold thickness, and arm circumference data can be statistically analyzed under comparable conditions.
Conclusions:
- Serial anthropometric measurements are vital for monitoring growth in children with kidney disease.
- Standard deviation scores are recommended for robust statistical comparison of stature.
- Further development is needed for statistically comparing other growth indices in group settings.
Abstract:
The serial measurement of stature, weight, skin-fold thickness, mean arm circumference, skeletal maturity, and where appropriate, stage of sexual development are recommended as suitable indices for assessing growth in children with kidney disease. Methods of expressing the data for evaluating the individual child are generally used methods. Emphasis is given to relating stature to bone age in evaluating growth potential. Methods for comparing growth rates in groups of children are less well-developed. Using standard deviation scores is recommended for comparing stature in two groups of children or in the same child observed at the end of two different regimens. Weight using ideal weight-for-height as reference from a group of children can be treated statistically. Data of skinfold thickness and arm circumference from two groups can be handled statistically only when the groups are comparable in age and sex.
