 The study found that a paper-based and region-adapted food frequency questionnaire, FFQ, designed to assess cardiovascular disease, CVD, related food and nutrient intakes of adolescents from northwest Mexico was moderately validated. The FFQ overestimated the intake of all food groups and nutrients, while Cohen's Capocoe efficiency were lower than 0.20. This suggests that the tool may not be reliable enough to use alone, but could be useful when combined with multiple administrations of 24-hour recalls, 24-hours, as a critical mean in future interventions intended to reduce cardio-metabolic risk in adolescents.
