Assessment of Child Anthropometry in a Large Epidemiologic Study
Published on: February 2, 2017
Anthropometry of Mexican-American migrant children in northern California
Insights
Mexican-American children in California showed adequate growth, with improved nutrition during their US stay. Most children had healthy hematocrit levels, contrasting with previous studies.
Area of Science:
- Pediatric Nutrition
- Growth Monitoring
- Migrant Health
Background:
- Previous studies indicated potential growth deficits in Mexican-American children.
- Understanding the nutritional status and growth patterns of migrant children is crucial.
Purpose of the Study:
- To assess the anthropometric data and hematocrit levels of Mexican-American migrant children.
- To compare growth percentiles with national standards and previous research.
Main Methods:
- Collected anthropometric data (weight-for-age, height-for-age, weight-for-height) from 209 children aged 0-7 years.
- Measured hematocrit levels in 170 children.
- Analyzed growth percentiles and their relationship with age and seasonal residence.
Main Results:
- Only 7.6% of children had low hematocrit levels.
- Growth percentiles approximated National Center for Health Statistics standards.
- Weight-for-height percentile increased with age, while height-for-age decreased; growth accelerated during US residence.
Conclusions:
- Mexican-American migrant children in this cohort exhibited adequate growth.
- Improved nutritional conditions in the US may contribute to their adequate growth status.
- Findings contrast with earlier studies, suggesting potential improvements in migrant child health.
Abstract:
Anthropometric data were obtained from 209 Mexican-American migrant children, aged 0 to 7 yr, in the Sacramento Valley of California. Hematocrit was measured for 170 children. Only 13 children (7.6%) had hematocrits below acceptable levels. Weight-for-age, height-for-age, and weight-for-height growth percentiles approximated the National Center for Health Statistics standards. Only 15% of the children were at or below the 10th percentile of height-for-age, and only 7% were above the 95th percentile of weight-for-height, in contrast to earlier studies of Mexican-American children. The mean percentile of weight-for-height increased significantly with age, while height-for-age decreased. The rate of growth in weight and height accelerated during their summer residence in the US, indicating that the adequate growth status of these children may be related to improved conditions for growth while in the US.
