Unhealthy eating habits are common among adolescents in Vietnam, where transitioning food environments increasingly offer energy‐dense micronutrient‐poor foods. Successful behavior change approaches must be feasible and acceptable, promoting local foods that are available, accessible, and preferred. Yet, few studies have investigated the potential of food‐based approaches for adolescents. We used linear programming to identify problem nutrients, local nutrient sources, and realistic food‐based recommendations (FBRs) to improve nutrient intake among girls 16–22 years in Thai Nguyen, Vietnam. We then identified a reduced set of FBRs to prioritize the most critical micronutrient gaps. Calcium and iron targets could not be met in any realistic diet modeling scenario. The best set of FBRs included seven recommendations which could meet intake targets for 9 of 11 modeled micronutrients. The best reduced set of three FBRs targeting iron and calcium only—although more feasible for behavior change—was less effective at improving intake of these nutrients since fewer foods were recommended. Given the difficulty of meeting calcium and iron targets using local foods within acceptable dietary patterns, additional interventions, such as supplementation, staple food fortification, or increasing the availability of affordable calcium‐ and iron‐rich foods, may be necessary to promote dietary adequacy for adolescent girls.
Gentrification is a complex and controversial process, where the influx of new, wealthier residents to previously run-down neighbourhoods brings change such as economic development, infrastructure investments and lower crime rates, but can be to the detriment of the original lower-income residents, who are either displaced, or stay but cannot take advantage of the new opportunities. Understanding how neighbourhood change affects food environments can shed light on the possible causal pathways between gentrification and urban health inequalities. This rapid evidence assessment reviewed evidence on the impact of gentrification on the healthfulness of food environments globally. Ten studies were identified through a systematic keyword search and assessed. We found limited evidence of an effect, with a small, albeit consistent, body of evidence mostly comprised of low- to medium-quality observational studies, all from high-income countries. Most studies examined effects on availability or affordability of food, finding an association between gentrification and increased availability of unhealthy foods, or reduced affordability for original low-income residents.
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.
