ABSTRACT To determine the reliability and validity of a 10-item questionnaire, the Food Label Literacy for Applied Nutrition Knowledge questionnaire.
Participants were elementary school children exposed to a 90-minute school-based nutrition program. Reliability was assessed via Cronbach α and intraclass correlation coefficient (ICC). Validity was assessed comparing the questionnaire's food choices using an objective metric of nutrition quality, the Overall Nutritional Quality Index (ONQI), via t test. Statistical significance was set at .05.
Four hundred ninety-nine children participated, 51% were female, and the average age was 8.6 (± 0.9) years. Cronbach α = .77 and ICC = 0.68 (between administrations) were observed. ONQI scores of correct responses were significantly higher when compared to the ONQI scores of incorrect responses (27.4 ± 9.4 vs 16.2 ± 9.4; P = .01).
The Food Label Literacy for Applied Nutrition Knowledge questionnaire was found to be both reliable and a valid measure of food label literacy in children taught the Nutrition Detectives program.

    ABSTRACT: Objectives. We assessed the feasibility of a 15-week nutrition education, physical activity, and media literacy program for children living in urban family homeless shelters. Methods. We developed a qualitative monitoring tool to evaluate program process and impact at 2 shelter sites in the Bronx, New York, from 2009 to 2012. Facilitators recorded indications of participants' understanding of intended messages and demonstrations of changes in attitudes and behaviors. Comments, insights, and actions were recorded as they occurred. Facilitators also documented barriers to delivery of content and activities as intended. We used content analysis to examine data for patterns and identify themes. Results. A total of 162 children participated at the 2 shelter sites. Analysis of qualitative data yielded 3 themes: (1) children's knowledge and understanding of content, (2) children's shift in attitudes or intentions, and (3) interpretations through children's life experience. Food insecurity as well as shelter food service and policies were important influences on children's choices, hunger, and sense of well-being. Conclusions. Children's experiences highlighted the need to advocate for shelter policies that adequately provide for children's nutritional and physical activity requirements and foster academic development.

    ABSTRACT: Obese or overweight children have an increased risk for chronic diseases. Targeting diet and exercise in schools could help prevent childhood obesity. We have previously shown the effectiveness of a 90-minute nutrition program in improving elementary school students' food-label literacy. The objective of this study was to investigate the effectiveness of a 45-minute version of the program. We conducted a pre-post study in a public school district, with no control group. We provided teacher training and program materials. Participants were 5th-grade students in 5 schools who had parental consent and were willing to take part. We condensed the program to a 45-minute lesson with a presentation and hands-on activity. The lesson showed students why and how to make healthful food choices based on Nutrition Facts panels and ingredient lists. The district's physical education teachers taught the lesson. The primary outcome measure was food-label literacy (ie, the ability to distinguish between more and less healthful foods using a validated test instrument with Nutrition Facts panels and ingredient lists). A total of 212 students completed pre-post measures. Following program delivery, we observed a significant gain of 16.2 percentage points in scores overall, ranging from 4.3 percentage points to 23.6 percentage points among schools. Results were similar to those achieved with the 90-minute program. The condensed nutrition program improved students' food-label literacy while requiring a minimal allocation of time. Further studies in other school districts would be useful.

    ABSTRACT: With the increasing recognition of health literacy as a worldwide research priority, the development and refinement of indices to measure the construct is an important area of inquiry. Furthermore, the proliferation of online resources and research means that there is a growing need for self-administered instruments. We undertook a systematic overview to identify all published self-administered health literacy assessment indices to report their content and considerations associated with their administration. A primary aim of this study was to assist those seeking to employ a self-reported health literacy index to select one that has been developed and validated for an appropriate context, as well as with desired administration characteristics. Systematic searches were carried out in four electronic databases, and studies were included if they reported the development and/or validation of a novel health literacy assessment measure. Data were systematically extracted on key characteristics of the instruments: breadth of construct ("generic" vs. "content- or context- specific" health literacy), whether it was an original instrument or a derivative, country of origin, administration characteristics, age of target population (adult vs. pediatric), and evidence for validity. 35 articles met the inclusion criteria. There were 27 original instruments (27/35; 77.1%) and 8 derivative instruments (8/35; 22.9%). 22 indices measured "general" health literacy (22/35; 62.9%) while the remainder measured condition- or context- specific health literacy (13/35; 37.1%). Most health literacy measures were developed in the United States (22/35; 62.9%), and about half had adequate face, content, and construct validity (16/35; 45.7%). Given the number of measures available for many specific conditions and contexts, and that several have acceptable validity, our findings suggest that the research agenda should shift towards the investigation and elaboration of health literacy as a construct itself, in order for research in health literacy measurement to progress.
