Selected factors affecting relative validity of Food Frequency Questionnaire SFFQ among preschool children – Krakow study

Journal Title: Medycyna Ogólna i Nauki o Zdrowiu - Year 2014, Vol 20, Issue 1


Background. Epidemiological studies of the relationship between health status and the mode of nutrition should be based primarily on valid assessment of the intake of food products and the intake of nutrients.Objective. The objective of the study was to assess the effect of selected demographic factors on the validity of semiquantitative Food Frequency Questionnaire (SFFQ) among three-year-old children from Krakow.Material and methods. The study group consisted of 172 three- ear-old children. The intake of energy and selected nutrients assessed, based on the SFFQ, were compared with the intake from repeated 24-h recalls. The attenuated Spearman rank correlation was used to assess the level of compatibility between the two methods adjusted for the variability in the referent method.Results. The highest correlation between SFFQ and three 24-h recalls was found for vitamin B2 (RS =0.635) and calcium (RS =0.605) intake, while the lowest – vitamins PP and A (RS =0.344 and RS =0.355, respectively). It was found that the strongest factor influencing the level of compatibility of the two methods was attending a nursery school by child. Differences were also discovered in the values of correlation coefficients according to the level of education and age of the mother, and body weight of the child.Conclusions. The intake of energy and all the nutrients examined based on the SFFQ was significantly higher, compared to the intake assessed by repeated 24-h recalls. Nevertheless, the validity of measurement of intake of energy and basic nutrients measured by the correlation method were found to be at the acceptable level, compared to other instruments used for assessing food- nutrition among preschool children.Key words: validation, nutrition, food frequency questionnaire, preschool children
