Nutrition Literacy Measurement Tool With Multiple Features for Chinese Adults

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.

Vegetables for Healthy Diets in Low- and Middle-Income Countries: A Scoping Review of the Food Systems Literature

Background: Vegetables are an essential element in healthy diets, but intakes are low around the world and there is a lack of systematic knowledge on how to improve diets through food system approaches. Methods: This scoping review assessed how studies of food systems for healthy diets have addressed the role of vegetables in low- and middle-income countries. We apply the PRISMA guidelines for scoping reviews to narratively map the literature to an accepted food systems framework and identify research gaps. Results: We found 1383 relevant articles, with increasing numbers over 20 years. Only 6% of articles looked at low-income countries, and 93% looked at single-country contexts. Over half of articles assessed vegetables as a food group, without looking at diversity within the food group. 15% looked at traditional vegetables. Issues of physical access to food were among the least studied food system topics in our review (7% of articles). Only 15% of articles used a comprehensive food system lens across multiple dimensions. There is also a research gap on the impacts of different policy and practice interventions (13% of articles) to enable greater vegetable consumption. Conclusions: Food system studies necessarily drew on multiple disciplines, methods and metrics to describe, analyze, and diagnose parts of the system. More work is needed across disciplines, across contexts, and across the food system, including understanding interventions and trade-offs, and impacts and change for diets particularly of marginalized population groups. Filling these gaps in knowledge is necessary in order to work toward healthy vegetable-rich diets for everyone everywhere.

Aquatic Animal Foods for Nutrition Security and Child Health

Background: Aquatic animal source foods (AASF) can provide vital nutrients and bioactive factors essential for human health, yet disparities in consumption patterns prevail globally. Limited evidence exists for the implications of AASF access on child health outcomes. Objective: This study aimed to examine global AASF intakes longitudinally in association with critical nutrient intakes and childhood stunting and anemia. Methods: The analysis draws from compiled longitudinal country data (1993-2013) based on a constructed conceptual framework encompassing social and ecological factors that influence fish consumption and human health. Longitudinal generalized linear models were used to estimate the association of apparent AASF intake on country-level nutrient availability (docosahexaenoic acid [DHA], choline, vitamin B12, iron, and zinc) and prevalence of undernourishment, child stunting, and child anemia. Results: Across 175 countries, the median per capita daily apparent intake of all AASF was 37.87 g, with marginally significant differences observed between countries with low (46.65 g) versus high child mortality (23.50 g). The combined category of all AASF was significantly associated with increased total apparent intakes of DHA, choline, and vitamin B12 and reduced child stunting. Finfish (pelagic and demersal) and crustaceans inversely correlated with child stunting, while apparent intakes of mollusks and crustaceans were associated with reduced child anemia. Conclusions: This study uniquely showed that AASF were associated with improved child health outcomes and the critical nutrients necessary for growth, development, and maintaining health throughout the life course. Policies should ensure increased access to AASF across food systems and within sustainable healthy diets globally.

Genotype Effects on β-Carotene Conversion to Vitamin A: Implications on Reducing Vitamin A Deficiency in the Philippines

Background: The study aimed to identify two beta-carotene 15,15′-monooxygenase (BCMO1) mutations, namely R267S and A379V, and determine their association with vitamin A status among Filipinos 6 to 19 years old respondents of the 2013 Philippine National Nutrition Survey living in the National Capital Region. Materials and Methods: This study followed cross-sectional design. Whole blood specimen was collected in the morning and was used as source of genomic DNA and serum for retinol concentration determination. Fisher exact test was performed to determine whether genotype frequencies were associated to retinol concentrations/vitamin A deficiency status. A level of P < .05 was identified as significant. Results: A total of 693 Filipino children and adolescents were included. Of the 693, there were at least 7.6% who bears the combined mutations for R267S + A379V. Association analysis showed that an inverse relationship exists between the A379V TT variant and vitamin A status. Although the exact role of these identified polymorphisms on retinol/carotenoid metabolism need to be confirmed in dedicated functional studies. Conclusion: This study has identified for the first time the presence of 2 nonsynonymous genetic variants/mutations in the coding region of BCMO1 gene. Interestingly, one of these two variants, the A379V T, was found to be associated with vitamin A status. It is, therefore, warranted to investigate the role of BCMO1 variants for the success of supplementation programs and fortification efforts among vulnerable populations in this region. Genetic variability should be considered for future provitamin A supplementation recommendations among children and adolescents in the Philippines.

Lessons Learned for Emergency Feeding During Modifications to 11 School Feeding Programs in Latin America and the Caribbean During the COVID-19 Pandemic

Background: School feeding programs (SFPs) can play a crucial role in the emergency food and nutrition response, but there is a dearth of information on how SFPs operate during emergencies. Design and Methods: A rapid comparative assessment of 11 SFPs throughout Latin America and the Caribbean during the COVID-19 pandemic. Data from (1) systematic document search and (2) surveys with key informants (n = 23) about barriers/facilitators to modifications were systematically analyzed using a multiple case study approach. Results: During the pandemic, all SFPs continued (although continuation plans varied from a few days in Chile to >1 month in Puerto Rico) via food kits, food vouchers, and/or grab n’ go meals. The SFP implementation was highly dependent on the programs’ autonomy and financial support, which impacted their logistics to acquire and distribute foods during the pandemic. The types of foods offered in some SFPs suggest that established nutritional guidelines were not always followed. Key informants expressed concerns about the deterioration of the nutritional quality of foods offered during the pandemic and lack of community engagement that impeded distribution to the neediest. Conclusions: Results underscore the urgency for clear implementation guidance on how to modify SFP during emergencies. Public health implications include (1) allocation of autonomous resources to an intersectoral working group to safeguard nutritional benefits during emergencies, (2) strengthening efforts of SFP community engagement before and during emergencies, and (3) establishing guidelines of the types of foods that can be distributed to meet the nutritional needs of beneficiaries during emergencies.

The Validation and Reliability of the Food and Health Questionnaire to Assess Health and Nutrition Knowledge

Purpose: This study aimed to translate and test the content validity and reliability of an English questionnaire used in the American food and health survey. Methods: The questionnaire was developed using 6 stages, then examined for test–retest. A total of 672 participants were recruited for validation and reliability. Validity test was performed using a correlation coefficient to measures the linear correlation between 2 questions at one given time. Moreover, the Kaiser-Meyer-Olkin, Measure of Sampling Adequacy, and Bartlett’s Test of Sphericity were performed to statistically determine the suitability for conducting exploratory factor analysis. Furthermore, reliability tests using Cronbach α was used to estimate the reliability coefficient properties of the translated scale. Finally, the most important correlated questions was plotted using a color-coded correlogram. Results: The test–retest reliability of all tested items was significantly correlated. The reliability test for all questions was 0.9. The cross-correlation test showed that all questions of the translated questionnaire were correlated significantly ( P < .05) indicating reliability of the questionnaire. Conclusion: The tested questionnaire is applicable and may be used in population-based studies to raise awareness regarding health, food consumption, nutrition, and food safety among people in Jordan and/or other Arab countries.

Leveraging the Scaling Up Nutrition Movement to Operationalize Stunting Prevention Activities: Implementation Lessons From Rural Malawi

Background: The rural district of Ntchisi is in the central region of Malawi. Among children aged 6 to 23 months, the stunting prevalence is 40% to 50%. To address this high prevalence, the World Food Programme, with cooperating partners, supported the Government of Malawi to implement an integrated stunting prevention program entitled The Right Foods at the Right Time from 2013 to 2018. Objective: To provide implementation lessons learned from systematic documentation of how the Scaling Up Nutrition (SUN) movement, combined with other international and national initiatives and policies, was translated into tailored programming. Methods: During program conception, early design, and implementation, this descriptive study systematically documented the process of translating SUN principles and government policies into an operational stunting prevention program in rural Malawi. Results: We identified 8 factors that contributed to successful translation of policy into program activities: (1) well-structured National SUN framework, (2) reliable coordination platforms and district ownership, (3) systematic and evidence-informed program design, (4) multiple forms of data used to inform program planning, (5) multisectoral implementation approaches to stunting prevention, (6) innovation in technology to improve overall program efficiency, (7) systematic collaboration among diverse stakeholders, and (8) strong public health nutrition capacity of program team members. Conclusions: Lessons from this nutrition program in Ntchisi, Malawi, provide one case illustrating how the SUN movement, government policies, and global evidence base can be operationalized into tailored programming for improving nutrition.

Relationships of Child-, Parents-, and Environment-Associated Determinants with Diet Quality, Physical Activity, and Smoking Habits among Indonesian Urban Adolescents

Background: The trend of unhealthy lifestyles is increasing among adolescents and has been associated with the rising burden of noncommunicable diseases (NCDs). However, specific determinants of unhealthy lifestyles among adolescents in low- and middle-income countries remain limited. Objective: To investigate the relationships of child-, parents-, and environment-associated determinants with diet quality, physical activity, and smoking habits among low-socioeconomic urban adolescents. Methods: A cross-sectional study involving 238 adolescents aged 11 to 17 years was conducted in Jakarta, Indonesia. Adolescents and their parents were interviewed to assess the determinants of healthy lifestyles that included diet quality, physical activity, and smoking habits. Diet and physical activity were quantified using the Diet Quality Index for Adolescents (DQI-A) and Physical Activity Questionnaire for Older Children (PAQ-C), respectively. Multiple regression was used to determine the β coefficients and odds ratios predictive of healthy lifestyles. Results: Mean scores of DQI-A and PAQ-C were considered low (33.5% ± 8.9% and 2.1 ± 0.5, respectively). Overall, 17.6% of adolescents were smokers, with 88% of these being males. Predictors of diet quality were child- (age, gender) and environment-associated (house size, access to a computer) determinants with β coefficients of −6.52 to 3.26. The PAQ-C score was associated with child- (female) and environment-associated (living area) determinants with β coefficients of −0.45 and 0.14, respectively. Younger adolescents and females were protective factors for smoking. Parents-associated determinants were not associated with any lifestyle indicators. Conclusions: Child- and environment-associated determinants were predictors of healthy lifestyles among adolescents. Thus, personal empowerment and environment transformation are needed to facilitate a healthy lifestyle and reduce the burden of NCDs among adolescents.

The High Burden and Predictors of Anemia Among Infants Aged 6 to 12 Months in Dar es Salaam, Tanzania

Background: Despite several interventions, the prevalence of anemia and related complications remains high among infants in Tanzania. Objective: We sought to determine the predictors of iron-deficiency anemia (IDA) among infants of HIV-negative women in Dar es Salaam, Tanzania. Methods: Cross-sectional analysis of 2826 mother–infant pairs who participated in a trial of vitamins and perinatal outcomes in Dar es Salaam, Tanzania. Hemoglobin and mean corpuscular volume were used to determine the prevalence of anemia among infants at 6 and 12 months. Multiple logistic regression was used to determine the maternal and infant risk factors for anemia during infancy. Results: We found high prevalence of anemia (90%) and IDA (44.2%) among infants. Higher maternal education (odds ratio [OR] = 0.52), maternal normal hemoglobin at enrollment (OR = 0.68) and during the early postpartum period reduced the odds of IDA at 6 months (OR = 0.56). The odds of IDA at 6 months were higher among males (OR = 1.65), wealth score below median (OR = 1.35), low birth weight (LBW; OR = 1.75), and small for gestational age (SGA) infants below the third centile (OR = 1.95) or third to less than fifth centile (OR = 2.29). Higher maternal education lowered the odds of IDA at 12 months (OR = 0.25). Wealth score below median (OR = 1.44), preterm delivery (OR = 1.94), SGA (less than third centile; OR = 2.40), and LBW (OR = 2.89) increased the odds of IDA during infancy in the study population. Dietary diversity was low for infants and women in the study sample. Conclusion: Interventions to reduce the risk of infant IDA should address women’s education, improvement of wealth status, and optimal care for premature, SGA, and LBW infants.

Household Decision-Making: Implications for Production, Consumption, and Sale of Nutrient-Rich Foods

Household decision-making influences choices related to the production, sale, purchase, and consumption of nutrient-rich foods. The present study assessed the effect of household decision-making in two regions of Ethiopia within two groups of households, most vulnerable households and model farmer households. The study focused on identifying barriers and facilitators relating to decisions about nutrient-rich foods—in this case fruits, vegetables, and animal source foods. The results provide insights into how future agricultural programs can affect key aspects of decision-making to maximize the positive impacts on diet and food security.
