Prevalence of stunting, wasting and underweight in Grade 1-learners: The NW-CHILD Study

Results: A higher prevalence of wasting and underweight were found amongst the boys (8.35%; 5.97%) compared with the girls (6.30%; 2.52%), although this was only significant for underweight (p = 0.02), whilst stunting percentages were very similar amongst girls (4.53%) and boys (4.06%). Underweight was the highest in the black group (5.47%; p < 0.01), compared with the white group (0.46%) and the prevalence of the conditions is associated with school types which represent low socio-economic circumstances (Quintile 1–3 schools). Only black learners showed stunting (p < 0.01) and more black learners were wasted (n = 39) compared with white (n = 15; p = 0.08) learners. Quintile 1–3 schools had a significantly higher prevalence of underweight (5.14% – 8.18%) and stunting (3.88% – 10.7%) (p < 0.01) compared with Quintile 4 and 5 schools.
