The objective of this cross-sectional study was to assess growth pattern of urban
school children in Malawi from low socio-economic strata and to compare anthropometric measurements of the children to data from the region of South-Central Africa and to international standards. A total of 493 urban school children aged 6±17 years were selected randomly from two primary schools in semi-urban Blantyre, the largest city in Malawi.
Anthropometric measurements included:
- height,
- weight,
- mid-upper arm circumference,
- triceps skinfold thickness,
- mid-upper arm muscle circumference
- maximal grip strength of the stronger hand.
All parameters of Malawian children of both sexes were lower than medians of WHO/NCHS reference data. Expressed as percentage of WHO/NCHS references, the relative means of height, weight, mid-upper arm circumference and mid-upper arm muscle circumference of Malawian girls were considerably higher than those of boys, and older girls had better parameters than younger ones.
Older pupils of both sexes had higher triceps skinfold thickness relative to the international references than the younger children. Mean maximal grip strength values of boys and girls were not significantly different. For girls, the relative values increased with age, while for boys they decreased. It is concluded that younger primary school pupils have similar body sizes to their counterparts from the region. Adolescents, particularly girls, have more favourable anthropometric parameters which approach WHO/NCHS reference data. |
