PURPOSE: Little is known about dietary intakes in toddlers of Low-German-Speaking Mennonites from Mexico, although some of these toddlers might be at risk for nutritional deficiencies. A 97-item, culturally sensitive, interviewer-administered food frequency questionnaire (FFQ) was developed and validated for health professionals to assess dietary intake in these children aged 12 to 36 months.
METHODS: Cultural foods on the FFQ were determined via focus groups; a pilot study tested content and formatting. The FFQ was administered to parents/caregivers of 22 toddlers in a southern Ontario community of Low-German-Speaking Mennonites from Mexico. Validity was determined by comparing nutrient intakes from the FFQ and from the 24-hour recalls, using Bland-Altman plots, Pearson correlations, and Student's t-tests. Test-retest reliability was compared between two FFQ administrations (n=14) one month apart, via intraclass correlations (ICCs).
RESULTS: Bland-Altman plots showed good agreement between the FFQ and the 24-hour recall; Pearson correlations between methods were significant for protein, folate, calcium, and caffeine. Student's t-tests were not significantly different between methods for 11 of 12 nutrients. Test-retest reliability was good on the basis of acceptable ICC for eight of 12 nutrients.
CONCLUSIONS: The prevalence of nutrient inadequacies was low, except for folate. These results are promising for implementation of a simple, quick, culturally sensitive FFQ with the potential to provide reliable estimates of mean intakes in toddlers of Low-German-Speaking Mennonites from Mexico.
