Preliminary assessment of the degree of food addiction through the Spanish Yale Food Addiction Scale for Children (S-YFAS-C) in a pilot pediatric population

INTRODUCTION: The Spanish Yale Food Addiction Scale for Children (S-YFAS-C) scale is the first tool adapted to Spanish to evaluate food addiction (FA) in the paediatric population. The aim of this study is to preliminarily evaluate the degree of FA in a non-clinical pilot paediatric population. MATERIAL AND METHODS: A transversal observational study was performed on a convenience sample comprised of boys and girls aged 9 to 12 (4th to 6th year primary school). The main outcome measures were evaluation of FA (S-YFAS-C scale), child feeding attitudes (ChEAT scale) and evaluation of body image (CDRS scale). Moreover, sociodemographic and anthropometric data were collected. A descriptive and bivariate analysis of the main characteristics of subjects and outcome measures was performed. RESULTS: A total of 21 boys and 24 girls were preliminarily evaluated and the minimum and maximum values obtained were for age (9.48–12.33), weight in kilograms (26.6–64.5), height in centimetres (131–163), BMI (14.2–27.9) and BMI Z-score (−1.36–2.66). The average number of FA symptoms measured with the S-YFAS-C scale is 1.67 ± 1.45 (range 0–7). A total of 20% of the sample shows three or more symptoms for FA, risk of developing a food disorder and distortion of the body image. Moreover, statistically significant differences were observed between desired body image in boys and girls (P = 0.001). CONCLUSIONS: The S-YFAS-C scale enables evaluating food addiction in Spanish-speaking boys and girls. The data obtained in regard to quantifying symptoms are similar compared to the original scale (S-YFAS-C: 1.67 ± 1.45 vs. YFAS-C: 2 ± 1.81). The option to score the counting of symptoms is the most sensitive measure to evaluate subclinical food behaviours.
