Background: Nutrition literacy is an emerging term which is increasingly used in policy and research. Progression is limited by the lack of an accepted method to measure nutrition literacy in Chinese adult, even research in this area is growing. Objective: The objective of this study is to develop a valid instrument to assess nutrition literacy in Chinese adults. Methods: The process involved 2 steps: constructed nutrition literacy conceptual framework, and developed potential items of scale based on literature review; and conducted 2 rounds of Delphi consultation to select items of the preliminary questionnaire. Results: In Delphi survey, the content validity index for each domain, level, and dimension of nutrition literacy was 1.0, coefficient of variation was less than 0.10, and Kendall’s coefficient of concordance was greater than 0.83. All of the 2 domains, 3 levels, and 6 dimensions initially formulated by our research team were reserved in the conceptual framework of nutrition literacy. Furthermore, a 43-item nutrition literacy measurement scale was established. Each item kept in the final scale reaches a high degree of concentration and a high degree of coordination, with the mean of importance ranging from 4.38 to 5.00. Conclusions: A nutrition literacy measurement scale with multiple features was established for Chinese adults, providing an operationalized tool to assess comprehensively nutrition literacy for research and practice in the field of nutrition, diet, and health.
Summary Background Hunger and obesity among young adolescents are serious public health issues; however, the relationship between these issues in this demographic has yet to be examined. Objective To determine whether both obesity and hunger coexist in young adolescents from a global perspective. Methods We analysed data of 142 565 adolescents (age, 12–15 years) from 60 countries from the Global School‐based Student Health Survey. Results Total prevalence of moderate and severe hunger was 22.32% and 7.8%, respectively—with the highest in Africa (29.14% and 12.14%, respectively) and the lowest in the Americas (16.83% and 5.31%, respectively). The prevalence of obesity among adolescents with severe hunger was 1.26 (95% confidence interval [CI]: 1.15–1.38) times the prevalence among those without hunger; however, this association varied across countries or regions. Moreover, the prevalence of obesity was 17% (95% CI: 1.04–1.29) higher in adolescent girls with moderate hunger in high‐income countries, 91% (95% CI: 1.23–2.58) higher in adolescents with severe hunger in low‐income countries and 54% (95% CI: 1.34–1.76) higher in lower middle–income countries compared to those without hunger. Conclusions Both obesity and hunger coexist in adolescent populations worldwide. Our findings emphasize the need for double‐duty actions to simultaneously address burdens of hunger and obesity among adolescents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
