Objective: School-based nutrition education can promote the development of skills, such as food label reading, that can contribute to making healthier food choices. The purpose of this study was to assess the reliability of a Russian language version of the previously validated Food Label Literacy for Applied Nutrition Knowledge (FLLANK) questionnaire and also to evaluate the impact of school-based nutrition education programmes on nutrition knowledge and food label-reading skills in Russian adolescents and young adults. Methods: Two nutrition education study programmes were administered to two separate groups of students--at a middle school (n?=?23) and a university (n?=?17). The study programmes consisted of a single 2-hour classroom session and emphasised basic nutrition and food components. The FLLANK questionnaire was administered to both groups of students before and after the intervention to assess change in food label-reading skills. Cronbach's a was calculated for the post-test scores to assess the instrument's internal consistency. Results: Middle school students increased their mean FLLANK scores from 54% to 95% (p?<0.01). University students increased their scores from 46% to 91% (p?<0.01). In the school group only, there was an interaction between time and gender, with boys improving significantly more than girls (p?<?0.05). The Cronbach's a estimates were low for both groups: -0.15 and 0.03 for school and university, respectively. Conclusion: Food label literacy improved among Russian adolescents and young adults after the implementation of nutrition education curricula. The translated version of the FLLANK retained its utility for capturing change in food label literacy, but performed very poorly with regard to internal consistency. Additional research with larger sample size and variance of scores to assess reliability is needed.
