Evaluating the outcomes and implementation determinants of interventions co-developed using human-centered design to promote healthy eating in restaurants: an application of the consolidated framework for implementation research.

Background: Restaurants are an emerging yet underutilized setting to facilitate healthier eating, particularly among minoritized communities that disproportionately experience health inequities. The present study aimed to examine outcomes from interventions co-developed using Human-Centered Design (HCD) in two Latin American restaurants, including sales of healthier menu items (HMI) and the consumer nutrition environment. In addition, we aimed to assess implementation outcomes (acceptability, fidelity, and sustainability) and elucidate the determinants for implementation using the Consolidated Framework for Implementation Research. Methods: This study used a mixed-methods, longitudinal design. Data were collected pre-, during, and post-intervention testing. Intervention outcomes were examined through daily sales data and the Nutrition Environment Measures Survey for Restaurants (NEMS-R). Changes in HMI sales were analyzed using interrupted time series. Implementation outcomes and determinants were assessed through site visits [observations, interviews with staff (n = 19) and customers (n = 31)], social media monitoring, and post-implementation key informant interviews with owners and staff. Qualitative data were analyzed iteratively by two independent researchers using codes developed a priori based on CFIR. Results: The HCD-tailored interventions had different outcomes. In restaurant one (R1), where new HMI were introduced, we found an increase in HMI sales and improvements in NEMS-R scores. In restaurant two, where existing HMI were promoted, we found no significant changes in HMI sales and NEMS-R scores. Acceptance was high among customers and staff, but fidelity and sustainability differed by restaurant (high in R1, low in R2). Barriers and facilitators for implementation were found across all CFIR constructs, varying by restaurant and intervention. Most relevant constructs were found in the inner setting (restaurant structure, implementation climate), individual characteristics, and process (HCD application). The influence of outer setting constructs (policy, peer pressure) was limited due to lack of awareness. Conclusion: Our findings provide insights for interventions developed in challenging and constantly changing settings, as in the case of restaurants. This research expands the application of CFIR to complex and dynamic community-based settings and interventions developed using HCD. This is a significant innovation for the field of public health nutrition and informs future interventions in similarly dynamic and understudied settings.

Area Characteristics and Consumer Nutrition Environments in Restaurants: an Examination of Hispanic Caribbean Restaurants in New York City.

Hispanics in the USA, particularly those of Caribbean descent, experience high levels of diet-related diseases and dietary risk factors. Restaurants are an increasingly important yet understudied source of food and may present opportunities to positively influence urban food environments. We sought to explore food environments further, by examining the association between neighborhood characteristics and restaurant consumer nutrition environments within New York City's Hispanic Caribbean (HC) restaurant environments. We applied an adapted version of the Nutrition Environment Measurements Survey for Restaurants (NEMS-R) to evaluate a random sample of HC restaurants (n=89). NEMS-HCR scores (continuous and categorized as low, medium, and high based on data distribution) were examined against area sociodemographic characteristics using bivariate and logistic regression analysis. HC restaurants located in Hispanic geographic enclaves had a higher proportion of fried menu items (p<0.01) but presented fewer environmental barriers to healthy eating, compared with those in areas with lower Hispanic concentrations. No significant differences in NEMS-R scores were found by other neighborhood characteristics. Size was the only significant factor predicting high NEMS-HCR scores, where small restaurants were less likely to have scores in the high category (NEMS-HCR score>6), compared with their medium (aOR: 6.6, 95% CI: 1.8-24.6) and large counterparts (aOR: 5.6, 95% CI: 1.5-21.4). This research is the first to examine the association between restaurant location and consumer nutrition environments, providing information to contribute to future interventions and policies seeking to improve urban food environments in communities disproportionately affected by diet-related conditions, as in the case of HC communities in New York City.

Understanding policy change for obesity prevention: learning from sugar-sweetened beverages taxes in Mexico and Chile.

This article examines the policy change process that resulted in the current sugar-sweetened beverages taxes in Mexico and Chile, using the Kaleidoscope Model for Policy Change, a framework developed for nutrition and food policy change analysis. We used a qualitative study design, including 24 key informant (KI) interviews (16 researchers, 5 civil society representatives and 3 food/beverage industry representatives), encompassing global and in-country perspectives. The analysis shows concurrence with the Kaleidoscope Model, highlighting commonalities in the policy change process. These included the importance of focusing events and coalitions for agenda-setting. Both top-down executive leadership and bottom-up pressure from civil society coalitions were important for the policy adoption as were flexible framing of the tax, and taking advantage of windows of opportunity. In both countries, the tax resulted from national, revenue-seeking fiscal reforms and in sub-optimal tax rates, as a result of the industry influence. KIs also discussed emerging evaluation results, highlighting differences in interpretation concerning the magnitude of change from the tax, and shared potential modifications to the current policies. This analysis contributes to a greater understanding of the policy change process focused on obesity prevention, using an innovative theoretical framework developed specifically for food and nutrition policy.

Ethnic Restaurant Nutrition Environments and Cardiovascular Health: Examining Hispanic Caribbean Restaurants in New York City.

Objective: To adapt and apply the Nutrition Environment Measures Survey for Restaurants (NEMS-R) to Hispanic Caribbean (HC) restaurants and examine associations between restaurant characteristics and nutrition environment measures. Methods: We adapted the NEMS-R for HC cuisines (Cuban, Puerto Rican, Dominican) and cardiovascular health-promoting factors, and applied the instrument (NEMS-HCR) to a random sample of HC restaurants in New York City (NYC) (N=89). Multivariable linear regression was used to assess independent associations between NEMS-HCR score and restaurant characteristics (cuisine, size, type [counter-style vs sit-down] and price). Results: None of the menus in the restaurants studied listed any main dishes as "healthy" or "light." More than half (52%) offered mostly (>75%) nonfried main dishes, and 76% offered at least one vegetarian option. The most common facilitator to healthy eating was offering reduced portion sizes (21%) and the most common barrier was having salt shakers on tables (40%). NEMS-HCR scores (100-point scale) ranged from 24.1-55.2 (mean=39.7). In multivariable analyses, scores were significantly related to cuisine (with Puerto Rican cuisine scoring lower than Cuban and Dominican cuisines), and size (with small [<22 seats] restaurants scoring lower than larger restaurants). We found a significant quadratic association with midpoint price, suggesting that scores increased with increasing price in the lowest price range, did not vary in the middle range, and decreased with increasing price in the highest range. Conclusions: Our application of the NEMS-R to HC restaurants in NYC revealed areas for potential future interventions to improve food offerings and environmental cues to encourage healthful choices.

Engaging Ethnic Restaurants to Improve Community Nutrition Environments: A Qualitative Study with Hispanic Caribbean Restaurants in New York City.

This study used interviews with New York City Hispanic Caribbean (HC) restaurant owners, managers, and cooks/chefs (n=19) to examine perceptions concerning the healthfulness of the HC diet and diet-related disparities in the HC community, and document factors potentially influencing their engagement in community nutrition interventions. The interviews revealed high awareness of diet-related issues. Respondents had mixed notions concerning their role in improving community food environments, noting important barriers for collaboration to consider in future interventions. The study underscores the important role of ethnic restaurants, providing information to facilitate engagement with this largely untapped sector in immigrant/ethnic communities in the US.

"It's Sort Of, Like, in My Family's Blood": Exploring Latino Pre-adolescent Children and Their Parents' Perceived Cultural Influences on Food Practices.

This study examined the perceived connections between culture and food practices among Latino pre-adolescents (n = 17) and their parents (n = 15) through semi-structured interviews. Results show that pre-adolescents have formed perceptions concerning the association between their eating behaviors and cultural background that coincide with their parent's notions. Participants associated culture to both healthy and unhealthy food practices. Latin American food environments were described as healthier than in the US. The interviews revealed conflict between traditional foods preferences and perceptions of health, underscoring the need for better approaches to help Latino families navigate US food environments, while also preserving healthful traditional food practices.

"We like Fried Things": Negotiating Health and Taste among Hispanic Caribbean Communities in New York City.

The study was conducted to understand fried-food (FF) consumption among Hispanic Caribbean (HC) communities in New York City. Data were collected through qualitative interviews with 23 adults self-identified as Cuban, Dominican, or Puerto Rican. Most informants considered FFs an important part of their traditional diet. Potential explanations included taste, cost, convenience, and the emotive values attached to FF. FF consumption was contextualized in local foodscapes. Results include strategies to diminish FF consumption and differences across HC groups and migratory generations. The relevance for future nutrition interventions addressing health disparities in this community is discussed.

Comparative analysis of dietary guidelines in the Spanish-Speaking Caribbean.

OBJECTIVE: Dietary guidelines are important education and policy tools to address local nutrition concerns. The current paper presents a comparative analysis of nutrition messages from three Spanish-speaking Caribbean countries (Cuba, Puerto Rico and Dominican Republic) to explore how these dietary guidelines address common public health nutrition concerns, contextualized in different changing food environments and food culture similarities. DESIGN: Qualitative, comparative analysis of current dietary guideline documents and key recommendations. RESULTS: Key recommendations were categorized into sixteen themes (two diet-based, ten food-based and four 'other'). Only the Cuban dietary guidelines included diet-based key recommendations. Of the ten food-based key recommendations, only four themes overlapped across the three dietary guidelines (the encouragement of fruits and vegetables, addressing protein sources and fat). Other overlaps were found between dietary guideline pairs, except between Cuba and Puerto Rico. Further analysis revealed differences in levels of specificity and acknowledgement of local dietary patterns and issues, as well as the need to revise the guidelines to account for current scientific advances. CONCLUSIONS: The present study underscored the importance of context in the framing of dietary advice and the influence of national socio-economic and political situations on nutrition policy and education efforts. The results contribute to inform efforts to improve nutrition communication in the region and among migrant communities.

Household-level dietary quality indicator for countries in nutritional transition: application to vulnerable communities in El Salvador.

OBJECTIVE: To develop a household-level diet quality indicator (HDQI) using the Salvadorian dietary guidelines to assess the dietary quality of households in vulnerable communities in El Salvador. DESIGN: The Salvadorian dietary guidelines were reviewed and eighteen HDQI components were identified (nine foods and nine nutrients). The components were evaluated using a proportional scoring system from 0 to 1, penalizing over- and under-consumption, where appropriate. The HDQI was validated in consultations with experts in El Salvador and by statistical analyses of the study sample data. Dietary variety and energy, nutrient and food intakes were compared among households above and below the median HDQI score using Student's t test. SETTING: Vulnerable, border communities in El Salvador. SUBJECTS: Households (n 140) provided food consumption information using an FFQ and sociodemographic data. RESULTS: The mean HDQI score was 63·5, ranging from 43·6 to 90·0. The indicator showed a positive, significant association with the dietary variety components. The statistical associations of the indicator with the energy and nutrient components were as expected. CONCLUSIONS: Based on the indicator's demonstrated face validity and the results of the expert consultations, the indicator is suggested as a good measure of diet quality for households in El Salvador.

Perceived access and actual intake of healthy diets among households in vulnerable Salvadoran communities.

OBJECTIVE: This study aimed to examine the dietary intake of Salvadoran households according to perceived access to healthy meals (PAHD), and to identify household characteristics associated with diet quality and PAHD. METHODS: Secondary data analysis with a sample of 139 Salvadoran households from resource-poor communities in El Salvador. Chi-square tests and ANOVA were used to assess differences in dietary intake across households classified according to PAHD. RESULTS: High-PAHD households had higher women's education, household food security levels, overall diet quality, and variety, and higher intakes of animal products, fats, cholesterol, vitamin C, and sodium (P < .05). Diet quality was not associated with the household characteristics studied. CONCLUSIONS AND IMPLICATIONS: Overall diet quality was associated with higher levels of PAHD, but some differences in intakes were not as expected, such as higher intakes in foods and nutrients associated with low-quality diets, among high PAHD households.
