Household expenditure surveys, covering fifteen days of household expenditures and including key food groups, are routinely conducted in low and middle income countries. This data may help identify patterns of food expenditure that influence child growth.
Objectives
We investigated the relationship between household food expenditures and child growth using four different analytic approaches.
Methods
We used data on 6,993 children from Ethiopia, India, Peru and Vietnam at ages 5, 8 and 12 yrs from the Young Lives cohort. We compared associations between household food expenditures and child growth (zhfa) using (a) total household food expenditures, (b) principal components, (c) factor analysis and (d) cluster analysis extracted from household expenditures on 13 different food groups, controlling for total food expenditures, round of data collection, rural/urban residence and child sex.
Results
Factors, principal components and indicators of clusters added significant information about zhfa over and above that provided by total food expenditures. Factors and principal components with loading on animal source foods and/or fruits and vegetables were significantly associated with higher zhfa in all countries except Ethiopia. Factors and principal components with loading on whole grains and pulses were significantly associated with lower zhfa in Peru, and higher zhfa in Ethiopia.
Conclusion
Household food expenditure data provides important insights into household food purchasing patterns that are significant predictors of zhfa. Including food expenditure data in analyses may yield important information about linear growth.
