Household food availability in Pelotas, Brazil: An approach to assess the obesogenic environment

Household Food Insecurity Negatively Impacts Diet Diversity in the Vietnamese Mekong Delta: A Cross-Sectional Study

Healthy, diverse diets are vital for life. In low/middle-income countries, however, the focus is more on food quantity rather than diet quality. This study assessed household diet diversity (HDD) in the Vietnamese Mekong Delta and its associations with household food insecurity (HFI) and household food availability (HFA) controlling for socioeconomic factors. Primary food-preparers in 552 randomly selected households in two rural provinces were interviewed about socioeconomic factors, HDD, HFI, and HFA. More than 80% of households predominantly consumed energy-dense foods, whereas less than 20% consumed nutrient-dense foods. Lower HDD was associated with HFI, lower HFA, for the Khmer ethnic minority, and low livelihood capitals (landlessness, low expenditure, debt) and low utensil scores. The study highlighted the need to provide improved food and nutrition policies that increase availability and access to diverse and healthy foods as well as reduce poverty and increase incomes for at-risk rural and ethnic minority groups.

Methodologies for assessing the household food availability in the context of food (in)security: a systematic review

This article aims to identify the methods used to assess household food availability in studies on food and nutritional security and to discuss its methodological aspects. Systematic review elaborated according to the PRISMA method. We searched at PubMed; Scielo and Lilacs databases, and studies that used methods of assessing the availability of food at home were included. In the end, 19 papers composed the review. Food availability was predominantly assessed for a seven days period and from a single data measurement. Other variables were also observed in the studies, such as socio-demographic data and expenditure on food. Among the limitations to assess the food availability at home, we can highlight the difficulty in measuring the food distribution among family members and the lack of information on the variability of this availability. Such assessment can be improved by investigating the strengths and weaknesses of the instruments for greater detail and accuracy of the information. We recommend the development and validation of specific instruments capable of effectively measure the food availability at the household level.

Determinants of fruits, vegetables, and ultra-processed foods consumption among infants

The objective was to evaluate the influence of individual and contextual determinants on infant's consumption of fruits and vegetables (FV), and ultra-processed foods (UPF). The data was obtained from the Survey of Prevalence of Breastfeeding in Brazilian Municipalities, 2008. A representative sample of 14,326 infants 6-11.9 months old, from seventy-five municipalities of São Paulo state was evaluated. The influence of determinants on FV and UPF consumption was analyzed using Poisson multilevel regression. Mother's educational level and maternal age had positive dose-response effect for the consumption of FV (p trend < 0.001) and negative for UPF (p trend < 0.001). Infants of multiparous women and those who received outpatient care in public medical system showed lower prevalence of FV (p < 0.001 for both) and higher prevalence of UPF (respectively, p < 0.001 and p = 0.001). Moreover, the contextual variable related to population size indicated that the prevalence of consumption of FV decreased (p < 0.001) and UPF increased (p = 0.081) with decreased population size. Therefore, infants born to women with low education levels, who received outpatient care in the public health network, and who reside in small municipalities should be prioritized for educational programs related to feeding practices.

A qualitative study exploring the dietary gatekeeper's food literacy and barriers to healthy eating in the home environment

ISSUE ADDRESSED

Food literacy has been recognised as a collection of interrelated food skills and knowledge to support healthy dietary outcomes. In the home environment, the dietary gatekeeper is the individual most responsible for food preparation, and therefore, has a significant influence on the family diet. This study explored how the dietary gatekeeper's food literacy skills are used to manage dietary barriers to facilitate healthy eating in the home environment.

METHODS

Qualitative data were collected from a sample of household dietary gatekeepers with children (n = 17). Participants were also instructed to take photographs of family meals prior to the interview and these were used as interview prompts to gain deeper insights into gatekeeper behaviour.

RESULTS

Participants reported the two most significant barriers to healthy eating in households were time pressure and fussy eating. Four strategies were identified that used gatekeepers' food literacy to manage these barriers: breaking up meal tasks; customising meals for family tastes; camouflaging healthy ingredients; and facilitating food choice autonomy. These strategies incorporated interrelated food literacy skills related to the planning, preparation, selection and eating domains.

CONCLUSION

The current findings highlight the dietary gatekeeper's food literacy as an interrelated concept and show how it is operationalised to successfully manage barriers to healthy eating experienced in the home environment. SO WHAT?: Future health promotion campaigns must offer tailored communications and interventions that provide resources and support to dietary gatekeepers to foster food literacy and counteract the influence of barriers to healthy eating.

Food Environment Research in Low- and Middle-Income Countries: A Systematic Scoping Review

Food environment research is increasingly gaining prominence in low- and middle-income countries (LMICs). However, in the absence of a systematic review of the literature, little is known about the emerging body of evidence from these settings. This systematic scoping review aims to address this gap. A systematic search of 6 databases was conducted in December 2017 and retrieved 920 records. In total, 70 peer-reviewed articles met the eligibility criteria and were included. Collectively, articles spanned 22 LMICs, including upper-middle-income countries (n = 49, 70%) and lower-middle-income countries (n = 18, 26%). No articles included low-income countries. Articles featured quantitative (n = 45, 64%), qualitative (n = 17, 24%), and mixed-method designs (n = 11, 8%). Studies analyzed the food environment at national, community, school, and household scales. Twenty-three articles (55%) assessed associations between food environment exposures and outcomes of interest, including diets (n = 14), nutrition status (n = 13), and health (n = 1). Food availability was associated with dietary outcomes at the community and school scales across multiple LMICs, although associations varied by vendor type. Evidence regarding associations between the food environment and nutrition and health outcomes was inconclusive. The paucity of evidence from high-quality studies is a severe limitation, highlighting the critical need for improved study designs and standardized methods and metrics. Future food environment research must address low-income and lower-middle-income countries, and include the full spectrum of dietary, nutrition, and health outcomes. Improving the quality of food environment research will be critical to the design of feasible, appropriate, and effective interventions to improve public health nutrition in LMICs.

Consumer food environment and overweight

OBJECTIVES

The aim of this study was to investigate the association between aspects of the consumer food environment in food stores selling fruit and vegetables (FVs) and the incidence of overweight among users of a Brazilian primary health care service.

METHODS

This cross-sectional study assessed individual-level and food environment variables, within the context of a representative sample of a primary health care service in a Brazilian city (the Health Academy Program [HAP]) in 2013. Users of HAP units and multiple aspects of the consumer food environment (availability, diversity, variety, quality, advertising, and price) related to FVs and ultraprocessed foods (UPFs) were examined. Multilevel logistic models were used to examine the relationships among overweight and consumer environment characteristics. We analyzed 2810 participants and audited 336 food stores.

RESULTS

More than 70% of stores had adequate diversity and variety of FVs; Regarding quality, only 24.5% of stores presented inadequate quality of fruits and 39.6% inadequate quality of vegetables. UPFs were present in 60.6% of FV stores. The results indicated a high prevalence of overweight (62.6%) in participants of the health promotion service and the multilevel models revealed an association with variety of vegetables in stores (0.99; 95% confidence interval, 0.97-0.99; P < 0.05).

CONCLUSIONS

Given the importance of food environment in food choice at the time of purchase, it is important to consider consumer food environment in determining consumption. The results suggest that increased exposure to healthy foods should be included as guidelines for weight management.
