Marginal malnutrition in school-aged Colombian boys: anthropometry and maturation
Insights
Nutritional deprivation in Colombian boys aged 6-16 years led to depressed growth and development. Reference data highlights that national standards can guide improvements for disadvantaged populations, emphasizing age-related growth cutoffs.
Area of Science:
- Pediatric Nutrition
- Anthropometry
- Public Health
Background:
- Nutritional status is critical for child development.
- Socioeconomic disparities impact growth in Colombian children.
- Establishing accurate nutritional reference data is essential.
Purpose of the Study:
- To classify nutritional status in Colombian boys using reference data.
- To investigate growth and maturation differences between socioeconomic groups.
- To evaluate the utility of national standards for disadvantaged populations.
Main Methods:
- Utilized Colombian reference data for weight and height.
- Classified 1108 boys (ages 6-16) into nutritional categories.
- Studied anthropometric measurements (growth, skinfolds, circumferences) and sexual maturation.
- Compared children from upper and lower socioeconomic urban and rural settings.
Main Results:
- Nutritionally deprived groups showed depressed growth, growth velocities, skinfolds, circumferences, and sexual maturation.
- Marginal malnutrition was indicated in lower socioeconomic and rural populations.
- Normal boys were identified in disadvantaged populations, suggesting potential for improvement.
Conclusions:
- Nutritional deprivation significantly impacts growth and development in Colombian boys.
- National growth standards can serve as aspirational goals for improving nutritional status in disadvantaged communities.
- Age-related cutoff points for growth are necessary for identifying marginal malnutrition, with head circumference being a potential early indicator.
Abstract:
Colombian reference data for weight and height were used to classify 1108 boys 6 to 16 yr old as nutritionally normal, low weight for age, and low weight for height. The normal group in upper socioeconomic urban and normal, low weight for age, low weight for height groups in lower socioeconomic urban and rural populations were studied. The achieved growth, growth velocities, skinfolds, mid-arm and head circumferences, and sexual maturation were all depressed in the nutritionally deprived groups indicating marginal malnutrition. Since normal boys exist in low socioeconomic and rural populations, normative data for economically advantaged children (national standards), on the average, may serve as desirable goals for low socioeconomic and rural populations. Different cutoff points for achieved growth might be established for marginal malnutrition using national or international reference populations. These ought to be age-related because of accumulated effect of slowed growth with age. Head circumference of school-aged children may proved a useful anthropometric tool in deciding early nutritional history.
