Integrating Theory With a User-Centered Design Approach to Maximize mHealth Acceptability and Usability
Mobile phone interventions are evidence-based methods for preventing obesity among Latino adults and school-aged children; however, few such interventions exist to improve the obesogenic behaviors of children in the developmentally critical preschool years (ages 2–5). Focusing on this age group is important since over one-quarter of 2- to 5-year-old Latino children are overweight or obese. Moreover, most documented interventions target mothers ex…
Characterizing household food security status, perceived neighborhood food environment, and food shopping behaviors among caregivers of children in the Hispanic Community Health Study/Study of Latinos…
U.S. Hispanic/Latino households disproportionally experience food insecurity, which may intersect with their food environments and food shopping behaviors to shape diet and health, but more representative findings are needed. We identified latent classes related to household food security (HFS), food environments, and food shopping behaviors among U.S. Hispanic/Latino households, and investigated their relationships with sociodemographic characte…

Eight pair-matched restaurants that met the eligibility criteria were randomized to a menu-only versus a menu-plus intervention condition…
Examination of the Relationship between In-Store Environmental Factors and Fruit and Vegetable Purchasing among Hispanics
Retail food environments have received attention for their influence on dietary behaviors and for their nutrition intervention potential. To improve diet-related behaviors, such as fruit and vegetable (FV) purchasing, it is important to examine its relationship with in-store environmental characteristics. This study used baseline data from the " El Valor de Nuestra Salud " study to examine how in-store environmental characteristics, such as produ…
Who is behind the stocking of energy-dense foods and beverages in small stores? The importance of food and beverage distributors
Objective The present study examined food and beverage distributors’ sourcing, placement and promotion of obesogenic (energy-dense, nutrient-poor) product categories from the perspective of small food store owners/managers. The obesogenic product categories of interest were savoury snacks, sugary beverages, sweet snacks, confectionery and frozen treats. Specifically, we examined how frequently distributors sourced these products, and the types of…

Food ordering for children in restaurants
Objective Restaurants are playing an increasingly important role in children’s dietary intake. Interventions to promote healthy ordering in restaurants have primarily targeted adults.

Latino fathers’ feeding-related parenting strategies on children’s eating
This study examined father and child sociodemographic characteristics in relation to fathers' feeding-related parenting strategies and whether their parenting strategies were associated with children's reported fruit and vegetable (FV), weekly fast-food, and daily sugar-sweetened beverage intake among 81 Latino father-child pairs. Father's employment status, acculturation, number of children in the home, and child's age and weight status were ass…
What influences Latino grocery shopping behavior? Perspectives on the small food store environment from managers and employees in San Diego, California
To inform the design of a multilevel in-store intervention, this qualitative study utilized in-depth semistructured interviews with 28 managers and 10 employees of small-to-medium-sized Latino food stores (tiendas) in San Diego, California, to identify factors within the tienda that may influence Latino customers' grocery-shopping experiences and behaviors. Qualitative data analysis, guided by grounded theory, was performed using open coding. Res…
