Background

Objective: This study aims to assess the relationship between Food and Nutrition Literacy (FNLIT) and dietary diversity score (DDS); FNLIT and nutrient adequacy (NAR%, MAR%) in school-age children in Iran. Results: This cross-sectional study was undertaken on 803 primary school students in Tehran, Iran. Socioeconomic , as well as three 24-h dietary recalls were collected through interviewing students and their mothers/caregivers. FNLIT was measured by a self-administered locally designed and validated questionnaire. Low level of FFNL was significantly associated with higher odds of low DDS (OR = 2.19, 95% CI 1.32-3.62), the first tertile of fruit diversity score (OR = 3.88, 95% CI 2.14-6.99), and the first tertile of dairy diversity score (OR = 9.60, 95% CI 2.07-44.58). Low level of IFNL was significantly associated with probability of lower meat diversity score (OR = 1.73, 95% CI 1.07-2.81). Low level of FLL was also significantly associated with probability of lower DDS (OR = 1.81, 95% CI 1.11-2.94), dairy diversity score (OR = 2.01, 95% CI 1.02-3.98), and meat diversity score (OR = 2.14, 95% CI 1.32-3.45).Low FNLIT and its subscales were associated with higher odds of low level of NAR of protein, calcium, vitamin B3, B6, B9, as well as the probability of lower level of MAR.

Purpose Functional dairy products market has been growing steadily in Iran. Awareness and perception related to these products has an important role in consumers’ acceptance and subsequently long-term marketplace success of these products. The purpose of this paper is to fill the knowledge gap in this regard, study conducted in Iran. Design/methodology/approach The theory of social marketing served as the framework of the study. Qualitative data were collected via eight semi-structured focus group discussions (FGDs), between May and September 2014. Participants were 65 women (44 housewives and 21 employed women), aged 23-68 years, selected by purposive sampling, with a maximum diversity. All FGDs were audio recorded and transcribed verbatim. Qualitative content analysis of the data was conducted by MAXQDA®. Findings Almost all participants were unfamiliar with the term “functional dairy products,” although, some of them had consumed these products. Apart from perceiving the functional dairy products as unnecessary by some participants, some women did not trust in health claims of these products for various reasons such as distrust in food manufacturers, exposure to contradictory information, and fear of unforeseen and dangerous side effects due to taking them. The participants agreed on the need for more information from a trusted and credible source such as health professionals or authorities through different communication channels like television, training classes, shopping center, and so on. Originality/value This study provides a unique insight into consumers’ awareness and perceptions concerning functional dairy products in Iran. To the best of the knowledge, this study is the first study in this regard in Iran. Given the novelty of these products in the market, the findings could provide information for the dairy industry to expand its market and improve its profitability and reliability, as well as public health sector to design and implement intervention programs to promote functional dairy products consumption in the population.

Background Food and nutrition literacy is a key factor in shaping healthy dietary behaviors and may result in decreasing decrease the prevalence of overweight. Empirical research on food and nutrition literacy and its outcomes is limited, especially among children and adolescents. Thus, this study investigates the link between Food and Nutrition Literacy (FNLIT) with eating behaviors, academic performance, and overweight in 10–12 years old students in Tehran, Iran. Methods This study was performed through two phases: 1) Proposing a conceptual model of the relationship between FNLIT and its determinants and outcomes, based on the existing evidence and previous models, and 2) Testing the proposed FNLIT model through a cross-sectional study on 803 primary school students (419 boys and 384 girls, from 34 public and 10 private primary schools), aged 10–12 years using structural equation modeling. Demographic, socio-economic, and household food security characteristics were collected by interviewing the students and their mothers/caregivers using a questionnaire. FNLIT was measured by a self-administered, locally designed, and validated questionnaire. Results The fit indices suggested a reasonably adequate fit of the data to the hypothesized model (χ2/df = 2.03, p < 0.001, goodness of fit index (GFI) = 0.90, adjusted goodness of fit index (AGFI) = 0.88, comparative fit index (CFI) = 0.91, incremental fit index (IFI) = 0.91, root mean square error of approximation (RMSEA) = 0.04, standardized root mean residual (SRMR) = 0.06). SES was directly and positively related to FNLIT and its subscale in students. FNLIT score had a positive direct (non-mediated) relationship with healthy eating behavior and academic performance. This pattern was strongly reversed in unhealthy eating behavior. There was a full mediation relationship between FNLIT and overweight/obesity via healthy eating behaviors. SES predicted academic performance partially through the mediating effect of Food Label Literacy (FLL). The results indicated that despite the direct relationship between SES and academic performance, an indirect but negative relationship existed with food insecurity. The finding also revealed the fully mediating role of Food Choice Literacy (FCL) in the relationship between demographic factors and healthy eating behaviors. Our study also found that Interactive Food and Nutrition Literacy (IFNL) protected unhealthy eating behaviors, and FCL predicted healthy eating behaviors in children. Conclusion Our study draws attention to FNLIT, especially the skills domain, including IFNL, FCL, and FLL, as the most important determinant of healthy eating behavior, academic performance, and weight status in school-age children reduces social inequalities in children’s development. To ensure an adequate level of FNLIT, educators should assess and plan to enhance food literacy skills in children and adolescents.
