The GUMLi EAT FFQ was shown to have good reliability and validity in assessing nutrient intakes in young children, with calibration factors used to adjust predicted estimates. The tool remained useful for ranking nutrient intakes in children under 2 years old, with similar estimated validity compared to other FFQs.
The Eating Assessment in Toddlers FFQ (EAT FFQ) has been shown to have good reliability and comparative validity for ranking nutrient intakes in young children. With the addition of food items (n 4), we aimed to re-assess the validity of the EAT FFQ and estimate calibration factors in a sub-sample of children (n 97) participating in the Growing Up Milk - Lite (GUMLi) randomised control trial (2015-2017). Participants completed the ninety-nine-item GUMLi EAT FFQ and record-assisted 24-h recalls (24HR) on two occasions. Energy and nutrient intakes were assessed at months 9 and 12 post-randomisation and calibration factors calculated to determine predicted estimates from the GUMLi EAT FFQ. Validity was assessed using Pearson correlation coefficients, weighted kappa (kappa) and exact quartile categorisation. Calibration was calculated using linear regression models on 24HR, adjusted for sex and treatment group. Nutrient intakes were significantly correlated between the GUMLi EAT FFQ and 24HR at both time points. Energy-adjusted, de-attenuated Pearson correlations ranged from 0 center dot 3 (fibre) to 0 center dot 8 (Fe) at 9 months and from 0 center dot 3 (Ca) to 0 center dot 7 (Fe) at 12 months. Weighted kappa for the quartiles ranged from 0 center dot 2 (Zn) to 0 center dot 6 (Fe) at 9 months and from 0 center dot 1 (total fat) to 0 center dot 5 (Fe) at 12 months. Exact agreement ranged from 30 to 74 %. Calibration factors predicted up to 56 % of the variation in the 24HR at 9 months and 44 % at 12 months. The GUMLi EAT FFQ remained a useful tool for ranking nutrient intakes with similar estimated validity compared with other FFQ used in children under 2 years.
