Reducing multifactorial stunting is a priority for the 2025 WHO Global Nutrition Target. In the plant-based complementary diets of low-income countries, deficits in several growth-limiting micronutrients may contribute to stunting. Hence the intercorrelation between multiple micronutrients in terms of their intake and impact is important. Therefore, our aim was to develop a nutrient quality score using principal component analysis (PCA) in a sample of Indonesian infants at 6, 9 and 12 months of age and to evaluate the association of the scores with linear growth and stunting. At 6 months, 217 infants were recruited from Sumedang District, West Java, with 195 and 189 followed at 9 and 12 months of age, respectively. Complementary food intakes were assessed using 2-d weighed food records. Eight correlated nutrients (vitamin A, ascorbic acid, thiamine, riboflavin, niacin, Ca, Fe and Zn) were summarised using PCA into …
