Cross-Sectional Association between Perceived Physical Literacy and Mediterranean Dietary Patterns in Adolescents: The EHDLA Study

Abstract

Purpose: The objective of the current study was to analyze the relationship between perceived physical literacy (PPL) and adherence to the Mediterranean Diet (MedDiet) and its specific components in a sample of Spanish adolescents. Methods: In this cross-sectional study, we examined a sample of 845 adolescents (58.1% boys) aged 12–17 years from the Valle de Ricote (Region of Murcia, Spain). PPL was assessed by the Spanish Perceived Physical Literacy Instrument for adolescents (S-PPLI). To assess adherence to the MedDiet, the Mediterranean Diet Quality Index in children and adolescents (KIDMED) was applied. Results: In unadjusted analyses, adolescents with medium or high PPL were more likely to have optimal adherence to the MedDiet (medium PPL: OR = 1.69, 95% CI 1.20–2.40, p-adjusted = 0.003; high PPL: OR = 2.90, 95% CI 2.03–4.17, p-adjusted < 0.001). These findings remained significant after adjusting for sex, age, socioeconomic status, body mass index, energy intake, overall sleep duration, physical activity, and sedentary behavior (medium PPL: OR = 1.51, 95% CI 1.05–2.19, p-adjusted = 0.003; high PPL: OR = 2.27, 95% CI 1.53–3.39, p-adjusted < 0.001). Conclusions: PPL could play a relevant role in the adoption of healthy eating habits among adolescents. Adolescents with low or medium PPL were less likely to report optimal adherence to the MedDiet. Adolescents with high PPL seem to consume more fruits, vegetables, fish, pulses, nuts, and dairies (for breakfast). Conversely, these adolescents tend to skip breakfast less, as well as to consume less commercially baked goods or pastries at this meal.
