    • Abstract:
      Objective. This study compared fruit and vegetable assessments derived from 4 self-administered questionnaires. Methods. Among 102 adolescents, servings of fruits and vegetables assessed by 4 questionnaires were compared with estimates from 24-hour recalls. Results. The prevalence of consuming 5 or more servings of fruits and vegetables a day was underestimated by the questionnaires. Questionnaires asking subjects to recall their diet over the previous year were more effective in ranking subjects (r's ≥.42) than those assessing previous-day diet (r's ≤.30). Conclusions. Brief assessments of fruit and vegetable intake are more useful for ranking subjects than for estimating prevalence of consumption of 5 or more servings per day. [ABSTRACT FROM AUTHOR]
