Abstract:
The effect of households' strategies on preschool children's intakes of vitamin A were examined in a rural Guatemalan village. The children's caretakers were interviewed regarding acquisition, preparation, storage and consumption of vitamin A sources on four separate occasions while children's intakes were measured by a seven-day food frequency questionnaire. The median daily intake of vitamin A was 128 μg and on average β-carotene constituted 45.5% of daily intake. Socioeconomic variables did not predict vitamin A intakes; only horse ownership was associated (r = .30, p < .05) with beta-carotene, but not total vitamin A intake. Purchased and cultivated sources were significant predictors of intakes. Of all the variables, household consumption of vitamin A was the prevailing predictor. However, household consumption was associated in a threshold fashion with children's intakes; it was a significant predictor of intakes only when household consumption was ≥ 11 food items measured over four days.
