Abstract

Introduction: Despite the broad usage of a Food Frequency Questionnaire (FFQ) in estimating food intakes, only a few studies have examined the usefulness of the FFQ to estimate fruit and vegetables (F&V) intakes as opposed to other methods such as food record in adolescents. This study aimed to examine whether F&V intakes observed using a FFQ is comparable to that of a 3-day food record (FR) in adolescents. Method: a secondary school at Seri Kembangan, Selangor was selected using multistage sampling. Out of 150 questionnaires that were distributed. 97 adolescents aged 16-17 returned complete questionnaires. The questionnaires consisted of three parts including socio-demographic information, FFQ & FR. Results: In general, a higher median intakes of F&V was observed using FR. A weak, negative correlation was found between total fruit intakes reported by FFQ and FR (r=-0.04, p=0.684). There was a weak, positive correlation between total vegetables intakes assessed using two methods (r=0.08, p=0.465). The tertile agreement for being in the same and adjacent cells between FFQ and FR was 74.2% for total fruit intakes and 78.4% for vegetables intakes. It was found that many participants reported low F&V intakes assessed using both FFQ and FR. Using Bland-Altman plots, mean difference of 90.54 g (95% CI=-209.88 g, 390.96 g) were indicated for fruit intakes and mean difference of -9.46 g (95% CI=-333.84 g, 310.92 g) for vegetables intakes. No significant association was found between agreement of F&V intakes per day and socio-demographic factors reported by adolescents aged 16-17 using both methods. Conclusion: FFQ showed moderate comparability against FR in assessing F&V intakes among adolescents aged 16-17. Low consumption of fruit and vegetables among the adolescents was found in current study. Therefore, intervention programs encouraging F&V intakes should be carried out in the future.
