Vj. Quinn et al., THE GROWTH OF MALAWIAN PRESCHOOL-CHILDREN FROM DIFFERENT SOCIOECONOMIC GROUPS, European journal of clinical nutrition, 49(1), 1995, pp. 66-72
Objective: The growth of Malawian preschool children from different so
cioeconomic groups was examined to determine the relevance of the NCHS
/WHO growth reference data for assessing child nutritional status in M
alawi. Design: The study involved a comparison of anthropometric data
from three cross-sectional surveys of preschool children over 24 month
s of age. Setting: Malawi, Central Africa. Subjects: Anthropometric me
asurements were taken on high income Malawian children (n = 380) durin
g a census of affluent preschools in the country's three major urban c
entres. Comparative data were obtained from two existing sample survey
s of low income urban children (n = 225) and rural village children (n
= 667). Results: The distribution of weight-for-age Z-scores (HAZ) fo
r the high income children 24-35 months of age closely resembled the N
CHS/WHO child reference population (mean HAZ = -0.21: SD = 1.05). Afte
r this age HAZ decreased to a mean value of -0.58 between 60 and 71 mo
nths, Large differences in growth were observed between children from
different socioeconomic groups, Regression analysis showed that at 24
months the high income children were, on average, 6.6 cm taller than t
he: low income urban children (P < 0.001), and 9.2 cm taller than the
rural children (P < 0.001). By 59 months of age these differences incr
eased to 9.6 cm and 11.1 cm, respectively, Conclusions: Although some
questions remain regarding the growth potential of Malawian children,
the results suggest the NCHS/WHO reference data are relevant for Malaw
i and the high levels of child stunting found in the country are due t
o environmental not genetic factors, Sponsorship: UNICEF/Malawi and Co
