|Abstract: ||In Northern Ghana, 33% of children are stunted due to economic disparities. Dietary fatty
acids (FA) are critical for growth, but whether blood FA levels are adequate in Ghanaian children
is unknown. The objective of this study was to determine the association between
whole blood FAs and growth parameters in Northern Ghanaian children 2–6 years of age. A
drop of blood was collected on an antioxidant treated card and analyzed for FA composition.
Weight and height were measured and z-scores were calculated. Relationships between
FAs and growth parameters were analyzed by Spearman correlations, linear regressions,
and factor analysis. Of the 307 children who participated, 29.7% were stunted and 8% were
essential FA deficient (triene/tetraene ratio>0.02). Essential FA did not differ between
stunted and non-stunted children and was not associated with height-for-age z-score (HAZ)
or weight-for-age z-score (WAZ). In hemoglobin adjusted regression models, both HAZ and
WAZ were positively associated with arachidonic acid (p 0.01), dihomo-gamma-linolenic
acid (DGLA, p 0.05), docosatetraenoic acid (p 0.01) and the ratio of DGLA/linoleic acid
(p 0.01). These data add to the growing body of evidence indicating n-6 FAs are critical in
childhood linear growth. Our findings provide new insights into the health status of an understudied
Northern Ghanaian population.|
