Food preferences are among the strongest predictors of the food choices of adolescents. These are associated with appetitive traits (food approach and avoidance) to some extent. However, no research has been conducted so far analyzing the association between food preferences and appetitive traits of adolescents. The aim of this study was to evaluate the associations between food preferences and appetitive traits in adolescents (aged 15-20 years) within the Polish Adolescents' COVID-19 Experience (PLACE-19) Study population. The PLACE-19 Study was carried out in a population-based sample of 2448 secondary school students sampled across the country (random quota sampling). Food preferences (including the preference for vegetables, fruit, meat/fish, dairy, snacks, and starches) of the adolescents were assessed using the validated Food Preference Questionnaire (FPQ) while their appetitive traits (hunger, food responsiveness, emotional overeating, enjoyment of food, satiety responsiveness, emotional undereating, food fussiness, slowness in eating) were assessed using the validated Adult Eating Behavior Questionnaire (AEBQ). The k-means clustering was performed to identify the homogenous clusters of respondents based on their preferences, and linear regression was performed to determine the relationship between food preferences and appetitive traits with a model adjusted for sex and age. Based on their preferences, three homogenous clusters of respondents were defined: low-preferring respondents (low preference for all food categories), respondents preferring snacking foods (low preference for all food categories, except for fruit and snacks), and high-preferring respondents (high preference for all food categories). The low-preferring respondents showed the lowest values for all appetitive traits (p = 0.0008), as well as the lowest total score (p = 0.0001), except for food fussiness, for which they showed the highest value (p = 0.0008). All preference scores were positively associated with traits such as hunger, food responsiveness, enjoyment of food, and emotional under-eating, while negatively associated with food fussiness (all p < 0.05). The largest amount of variance was observed for preference for dairy (14.6%; R2 = 0.146, p = 0.008) and snacks with respect to enjoyment of food (16.2%; R2 = 0.162, p = 0.008), for vegetable with respect to food fussiness (22%; R2 = 0.220, p = 0.008), and for meat/fish with respect to enjoyment of food (19.9%; R2 = 0.199, p = 0.008) and food fussiness combined (19.1%; R2 = 0.191, p = 0.008). These results support the association of food preferences with both food approach traits and food avoidance traits.
