Insights
Children with moderate and persistent malnutrition (MPEM) exhibited lower physical work capacity (PWC 170) and poorer anthropometric indicators compared to controls. These findings suggest impaired physical performance in undernourished children.
Area of Science:
- Pediatric Nutrition
- Exercise Physiology
- Child Health
Context:
- Study conducted in Beijing, 1987, involving 292 nine-year-old primary school children.
- Children were classified using international weight-for-height references.
- Comparison groups included children with moderate and persistent energy malnutrition (MPEM) and control groups.
Purpose:
- To assess the physical work capacity (PWC 170) and anthropometric indicators of children with MPEM.
- To investigate potential differences in physical performance between malnourished and well-nourished children.
- To explore the relationship between nutritional status and physical fitness in school-aged children.
Summary:
- MPEM children showed significantly lower PWC 170 and anthropometric indicators than controls.
- Mid-arm circumference differed significantly between MPEM and control groups, but not between sexes.
- Higher heart rates during testing in MPEM children indicated poorer work performance; anemia was ruled out as a cause.
Impact:
- Highlights the detrimental effect of MPEM on children's physical work capacity and overall physical development.
- Provides evidence for impaired physiological responses to physical exertion in malnourished children.
- Underscores the importance of nutritional status for optimal physical performance in childhood.
Abstract:
This study was performed during April through July, 1987 in Beijing. Classified by international reference of weight for height, a sample of 292 children, 9-yrs of age from five primary schools in BJ. The main conclusions were: compared with control groups, the value of PWC 170 of MPEM groups was significantly lower, so were the anthropometric indicators. The values of mid-arm circumference showed no significant difference between the sexual groups, but there was very significant difference between the MPEM and control groups. The value of PWC170 of boys was significantly higher than that of girls. Hemoglobin mean values were within the normal range and no significant differences were found in all groups. This meant that the differences of PWC170 of groups were not due to anemia. Transferrin mean value was significantly lower in MPEM than in control groups in girls. The heart rates, during testing, were significantly higher in MPEM than in control groups. This difference was taken to be evidence that work performance was poorer in MPEM than in controls.
