Dietary patterns of 6-24-month-old children are associated with nutrient content and quality of the diet.

We determined the associations of dietary patterns with energy/nutrient intakes and diet quality. Previously collected single 24-hr dietary recalls for children aged 6-11 months (n = 1,585), 12-17 months (n = 1,131), and 18-24 months (n = 620) from four independent studies in low socio-economic populations in South Africa were pooled. A maximum-likelihood factor model, with the principal-factor method, was used to derive dietary (food) patterns. Associations between dietary pattern scores and nutrient intakes were determined using Kendall's Rank Correlations, with Bonferroni-adjusted significance levels. For both 6-11 months and 12-17 months, the formula milk/reverse breast milk pattern was positively associated with energy and protein intake and mean adequacy ratio (MAR). The family foods pattern (6-11 months) and rice and legume pattern (12-17 months) were positively associated with plant protein, fibre, and PU fat; both for total intake and nutrient density of the complementary diet. These two patterns were also associated with the dietary diversity score (DDS; r = 0.2636 and r = 0.2024, respectively). The rice pattern (18-24 months) showed inverse associations for nutrient intakes and nutrient densities, probably because of its inverse association with fortified maize meal. The more westernized pattern (18-24 months) was positively associated with unfavourable nutrients, for example, saturated fat and cholesterol. These results highlight that underlying dietary patterns varied in terms of energy/nutrient composition, nutrient adequacy, nutrient densities of the complementary diet, and dietary diversity.
