The term food literacy is emergent, and as a result the literature reflects a great variety of definitions. Simultaneously, new research and food literacy programming is being developed without an agreed upon definition of what food literacy is and how food skills, food security, and health literacy may fit with the definition. We undertook a scoping review and conceptual analysis to identify how the term is understood and to determine shared components of definitions. We found that although most definitions included a nutrition and food skills component, there was great variation in how the ability to access, process, and enjoy food was affected by our complex food system. We propose a definition of food literacy that includes the positive relationship built through social, cultural, and environmental experiences with food enabling people to make decisions that support health. We offer a framework that situates food literacy at the intersection between community food security and food skills, and we assert that behaviours and skills cannot be separated from their environmental or social context. The proposed definition and framework are intended to be guiding templates for academics and practitioners to position their work in education and advocacy, bringing together separate spheres for collective action.

Health literacy has come to play a critical role in health education and promotion, yet it is poorly understood in adolescents and few measurement tools exist. Standardized instruments to measure health literacy in adults assume it to be a derivative of general literacy. This paper reports on the development and the early-stage validation of a health literacy tool for high school students that measured skills to understand and evaluate health information. A systematic process was used to develop, score and validate items. Questionnaire data were collected from 275, primarily 10th grade students in three secondary schools in Vancouver, Canada that reflected variation in demographic profile. Forty-eight percent were male, and 69.1% spoke a language other than English. Bivariate correlations between background variables and the domain and overall health literacy scores were calculated. A regression model was developed using 15 explanatory variables. The R(2) value was 0.567. Key findings were that lower scores were achieved by males, students speaking a second language other than English, those who immigrated to Canada at a later age and those who skipped school more often. Unlike in general literacy where the family factors of mother's education and family affluence both played significant roles, these two factors failed to predict the health literacy of our school-aged sample. The most significant contributions of this work include the creation of an instrument for measuring adolescent health literacy and further emphasizing the distinction between health literacy and general literacy.

With the rising concern over chronic health conditions and their prevention and management, health literacy is emerging as an important public health issue. As with the development of other forms of literacy, the ability for students to be able to access, understand, evaluate and communicate health information is a skill best developed during their years of public schooling. Health education curricula offer one approach to develop health literacy, yet little is known about its influence on neither students nor their experiences within an educational context. In this article, we describe our experience applying a social ecological model to investigating the implementation of a health education curriculum in four high schools in British Columbia, Canada. We used the model to guide a conceptual understanding of health literacy, develop research questions, select data collection strategies, and interpret the findings. Reflections and recommendations for using the model are offered.

Physical activity was monitored for 65 boys and girls, during family child care, using accelerometry. Average accelerometer wear time was 7.0 h (SD = 0.83), and average counts per epoch were 104.6 (SD = 31.6). Mean minutes per hour of moderate-vigorous physical activity and sedentary behaviour were 1.76 min (SD = 0.90) and 39.49 min (SD = 4.50), respectively. The very low levels of moderate-vigorous physical activity suggest that the young children in this study may be insufficiently active during child care.
