Using different approaches to assess the reproducibility of a culturally sensitive quantified food frequency questionnaire

The objective of this article was to report on the use of different approaches to assess the reproducibility of a culturally sensitive quantified food frequency questionnaire (QFFQ) used for assessment of the habitual dietary intake of Setswana-speaking adults in the North West Province of South Africa.

A previously developed and validated QFFQ was completed by trained fieldworkers. Portion sizes were estimated using different methods. Food intake was coded and analysed for nutrient intake per day for each subject.

Results show that more than one statistical approach is needed to assess the reproducibility of a QFFQ. The reproducibilityof this culturally sensitive QFFQ was good.
