Fruit and vegetable intake has been associated with a reduced risk of many chronic diseases. These foods are the main dietary source of carotenoids. The aim of the present study was to evaluate the associations between dietary intake and serum concentrations of alpha- and beta-carotene in a sample of young Finnish children from the population-based birth cohort of the Type 1 Diabetes Prediction and Prevention (DIPP) Study. The current analysis comprised 3-day food records and serum samples from 207 children aged 1, 2 and 3 years. Spearman and partial correlations, as well as a cross-classification analyses, were used to assess the relationship between dietary intake and the corresponding biomarkers. Serum concentrations of alpha- and beta-carotene were significantly higher among the 1-year-old compared to the 3-year-old children. Dietary intakes of alpha- and beta-carotene correlated significantly with their respective serum concentrations in all age groups, the association being highest at the age of 1 year (alpha-carotene r = 0.48; p < 0.001 and beta-carotene r = 0.47; p < 0.001), and lowest at the age of 3 years (alpha-carotene r = 0.44; p < 0.001 and beta-carotene r = 0.30; p < 0.001). A cross-classification showed that 72-81% of the participants were correctly classified to the same or adjacent quartile, when comparing the reported dietary intakes and the concentrations of the corresponding carotenoid in serum. The 3-day food record seems to be reasonably valid in the assessment of root vegetable consumption among young Finnish children. Root vegetables were the main dietary source of both carotenoids in all age groups. The high consumption of commercial baby foods among the 1-year-old children was reflected in the relatively high dietary intake and serum concentration of both carotenoids.
