A. van; Marcos, Ascensión CSIC ORCID; Cuenca García, María Luisa; Ottevaere, C.; González-Gross, Marcela CSIC ORCID; Moreno, Luis A.; Kafatos, Anthony; Leclercq, Catherine | Fecha de publicación: | 2013 | Editor: | Elsevier | Citación: | Nutrition 29: 411- 419.e3 (2013) | Resumen: | Objective: The present study assessed whether compliance with the Food-Based Dietary Guidelines is related to habitual fatty acid (FA) intake and blood lipid parameters. Methods: Dietary information was collected by two non-consecutive 24-h recalls in 1804 European adolescents. Compliance with the Food-Based Dietary Guidelines was expressed by calculating the Diet Quality Index for Adolescents (DQI-A). Blood samples were collected in a randomly selected subset (n = 552). Relations between FA intake/serum concentrations and DQI-A were tested with multilevel regression analysis to correct for the study design (clustering within cities). Analyses were stratified for gender; age was entered as a covariate. Results: Better DQI-A scores were related to increased proportional intakes of energy from total fat, saturated FA, monounsaturated FA, and cholesterol (P < 0.001), whereas no significant association was observed with polyunsaturated FA intakes. In adolescents with higher compared with lower DQI-A scores, dairy products contributed more (21.0% versus 12.7%) and low-nutrient, energy-dense items contributed less (17.2% versus 26.3%) to the intake of total fat. A positive association was observed between the DQI-A scores and serum concentrations of eicosapentaenoic acid and docosahexaenoic acid (all P < 0.005). The latter, however, was significant only in girls. In boys, higher DQI-A scores were inversely associated with serum cholesterol concentrations (P < 0.05). Conclusion: Although compliance with the Food-Based Dietary Guidelines was not always associated with a favorable FA intake pattern, a significant favorable association with some serum biomarkers was observed. This outcome underlines the importance of considering dietary habits instead of single-nutrient intakes. © 2013 Elsevier Inc. | URI: | http://hdl.handle.net/10261/65836 | DOI: | 10.1016/j.nut.2012.07.007 | Identificadores: | doi: 10.1016/j.nut.2012.07.007 issn: 0899-9007 |
