Abstract

We designed an image-based dietary assessment tool called COFIT, which means “fit together” and pilot-tested it in the Taipei Puberty Longitudinal Study (TPLS). Children aged 6–17 years were invited to use COFIT over three days for recording all instances of eating in addition to maintaining written food records (FR). Spearman’s correlation and Bland–Altman analysis were used to compare the intake of macronutrients and micronutrients estimated using the image-based dietary assessment and the FR method. Intra-class correlation coefficients were used to estimate reliability between dietitians. In the final analysis, 23 children (mean age: 10.47 ± 0.47 years) with complete data obtained using two dietary assessment methods were included. Reliability among dietitians was high. Most assessments of macronutrients and micronutrients revealed moderate correlations between the two methods (range: 0.27–0.94); moreover, no significant differences in nutrients assessments were observed between the two methods, except for energy and fat. The average difference in energy intake between the methods was 194 kcal/day. Most limits of agreement were within an acceptable range. The Bland–Altman plots showed robust agreement with minimum bias. The limitation was the small sample size and not dividing the population into children and teenagers since the two groups may have different food consumption habits. Overall, the results showed that the image-based assessment tool is suitable for assessing children’s dietary intake of macronutrients and micronutrients during pubertal growth.

Highlights

Adequate and balanced nutrition is essential for the pubertal growth of children and adolescents [1,2]
A total of 23 children with at least three days of complete written food records (FR) and image-based dietary assessment records were included in our analysis
The children’s body mass index (BMI) standards varied according to their age; we classified BMI into four groups according to growth charts for Taiwanese children [29]

Summary

Introduction

Adequate and balanced nutrition is essential for the pubertal growth of children and adolescents [1,2]. The precise assessment of the nutritional intake of young children remains a challenge in clinical practice. Previous studies have indicated that traditional methods, such as 24-h dietary recall (24-HDR) and food records (FR), may be limited by recall bias [3,4,5]. From the self-reported dietary recall of the children themselves, the dietitian may not be able to accurately record “real-time”. 24-HDR is frequently completed by children’s primary caregivers, but they often fail to capture the actual 24-h dietary intake of their children, their intake at school during lunch [4,7]. If children need to spend a long time memorizing and documenting food, it may increase respondent burden [5]
