Both malaria and undernutrition are major causes of paediatric mortali
ty and morbidity in sub-Saharan Africa. The introduction of insecticid
e-treated bed nets (ITBN) during a randomized controlled trial on the
Kenyan coast significantly reduced severe, life-threatening malaria an
d all-cause childhood mortality. This paper describes the effects of t
he intervention upon the nutritional status of infants aged between 1
and 11 months of age. Seven hundred and eighty seven infants who slept
under ITBN and 692 contemporaneous control infants, were seen during
one of three cross-sectional surveys conducted during a one year perio
d. Standardized weight-for-age and mid-upper arm circumference measure
s were significantly higher among infants who used ITBN compared with
control infants. Whether these improvements in markers of nutritional
status were a direct result of concomitant reductions in clinical mala
ria episodes remains uncertain. Never-the-less evidence suggests that
even moderate increases in weight-for-age scores can significantly red
uce the probability of mortality in childhood and ITBN may provide add
itional gains to child survival,beyond their impressive effects upon m
alaria-specific events. (C) 1997 Elsevier Science B.V.
