Comparison of 4 questionnaires for assessment of fruit and vegetable intake

Am J Public Health. 1998 Aug;88(8):1216-8. doi: 10.2105/ajph.88.8.1216.


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 > or = .42) than those assessing previous-day diet (r's > or = .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.
