Developing and testing a produce prescription implementation blueprint to improve food security in a clinical setting: a pilot study protocol.

BACKGROUND: Food insecurity is common in the United States, especially in Rhode Island, where it affects up to 33% of residents. Food insecurity is associated with adverse health outcomes and disproportionally affects people from minoritized backgrounds. Produce prescription programs, in which healthcare providers write "prescriptions" for free or reduced cost vegetables, have been used to address food insecurity and diet-related chronic disease. Although there is growing evidence for the effectiveness of produce prescription programs in improving food security and diet quality, there have been few efforts to use implementation science methods to improve the adoption of these programs. METHODS: This two-phase pilot study will examine determinants and preliminary implementation and effectiveness outcomes for an existing produce prescription program. The existing program is funded by an Accountable Care Organization in Rhode Island and delivered in primary care practices. For the first phase, we conducted a formative evaluation, guided by the Consolidated Framework for Implementation Research 2.0, to assess barriers, facilitators, and existing implementation strategies for the produce prescription program. Responses from the formative evaluation were analyzed using a rapid qualitative analytic approach to yield a summary of existing barriers and facilitators. In the second phase, we presented our formative evaluation findings to a community advisory board consisting of primary care staff, Accountable Care Organization staff, and staff who source and deliver the vegetables. The community advisory board used this information to identify and refine a set of implementation strategies to support the adoption of the program via an implementation blueprint. Guided by the implementation blueprint, we will conduct a single-arm pilot study to assess implementation antecedents (i.e., feasibility, acceptability, appropriateness, implementation climate, implementation readiness), implementation outcomes (i.e., adoption), and preliminary program effectiveness (i.e., food and nutrition security). The first phase is complete, and the second phase is ongoing. DISCUSSION: This study will advance the existing literature on produce prescription programs by formally assessing implementation determinants and developing a tailored set of implementation strategies to address identified barriers. Results from this study will inform a future fully powered hybrid type 3 study that will use the tailored implementation strategies and assess implementation and effectiveness outcomes for a produce prescription program.

Results from the Strong Families Start at Home/Familias Fuertes Comienzan en Casa: feasibility randomised control trial to improve the diet quality of low-income, predominantly Hispanic/Latinx children.

OBJECTIVE: To describe the feasibility, acceptability and results of Strong Families Start at Home, a 6-month pilot trial of a home-based food parenting/nutrition intervention. DESIGN: Pilot randomised controlled trial. SETTING: Participants received six visits with a community health worker trained in motivational interviewing (three home visits, three phone calls); an in-home cooking or reading activity; personalised feedback on a recorded family meal or reading activity; text messages and tailored printed materials. PARTICIPANTS: Parents and their 2-5-year-old child were randomised into intervention (responsive food parenting practices/nutrition) or control (reading readiness) groups. RESULTS: Parents (n 63) were mostly mothers (90 %), Hispanic/Latinx (87 %), born outside the USA (62 %), with household incomes <$25 k (54 %). Despite delivery during COVID-19, 63 % of dyads were retained at 6 months. The intervention was delivered with high fidelity. All parents in the intervention group (n 24) expressed high levels of satisfaction with the intervention, which produced positive treatment effects for whole and total fruit component Healthy Eating Index-2015 scores (point estimate (PE) = 2·14, 95 % CI (0·17, 1·48); PE = 1·71, 95 % CI (0·16, 1·47), respectively) and negative treatment effects for sodium (PE = -2·09, 95 % CI (-1·35, -0·04)). Positive treatment effects also resulted for the following food parenting practices: regular timing of meals and snacks (PE = 1·08, 95 % CI (0·61, 2·00)), reducing distractions during mealtimes (PE = -0·79, 95 % CI (-1·52, -0·19)), using food as a reward (PE = -0·54, 95 % CI (-1·35, -0·04)) and providing a supportive meal environment (PE = 0·73, 95 % CI (0·18, 1·51)). CONCLUSION: Given the continued disparities in diet quality among low-income and diverse families, continued efforts to improve child diet quality in fully powered intervention trials are needed.

Maternal Experiences with Discussing Complementary Feeding in Primary Care.

Complementary feeding practices promote healthy eating habits and food preferences later in life. Little is known about how US pediatricians communicate infant feeding practices to caregivers or how caregivers respond to this information. The purpose of this study is to explore mothers' experiences and perceptions of the complementary feeding recommendations they receive in primary care settings. English- and Spanish-speaking mothers of infants were recruited from Special Supplemental Nutrition for Women, Infants, and Children offices in Rhode Island, US, and snowball sampling. Semi-structured telephone interviews were conducted to investigate mothers' discussions with pediatricians about complementary feeding and their overall impressions of wellness visits. Thematic analysis was informed by the Fundamentals of Care theoretical framework. The mean age of the sample (n = 13) was 30.5 years and 62% self-identified as Latina. Four themes emerged from the analysis: (1) wellness visits are mostly positive experiences, (2) not all infant feeding recommendations are easy to follow, (3) alternative sources of infant feeding recommendations can be just as helpful, and (4) there is room for improvement at wellness visits. Improving the content, delivery, and cultural relevance of infant feeding recommendations in primary care settings with more specific and tailored information may promote adherence to evidence-based practices.

A recurrent cross-sectional qualitative study exploring how low-income mothers define snacks and reasons for offering snacks during infancy.

Despite rapid increases in snacking in recent decades, little is known about snacking during infancy. This study explored how low-income mothers define snacks and their reasons for offering snacks during infancy. A recurrent cross-sectional qualitative approach was used to identify themes from semi-structured interviews with low-income mothers when their infants were 6 and 12 months of age. A purposive sample of mothers (N = 15) was recruited from Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) offices and childcare centers serving low-income families in Rhode Island. Mothers also completed demographic and infant feeding questionnaires. Independent thematic analyses were conducted to identify themes from the 6 and 12 month interviews. Themes from the 6 month interviews for how mothers defined snacks were: snacks are consumed between meals, snacks are smaller portions, and snacks are sweet. Themes from the 12 month interviews also included snacks are consumed between meals and snacks are smaller portions with one additional theme: snacks do not include all food groups. Themes from the 6 month interviews for the reasons mothers offered snacks were: infants seemed hungry, infants showed interest, and snacks help manage behavior. Themes from 12 month interviews also included snacks help manage behavior with two additional themes: snacks expose infants to different flavors and snacks expose infants to different textures. Findings suggest that snacks are commonly offered during infancy and that mothers define snacks as smaller portions that help with hunger between meals. However, during early infancy mothers describe snacks as sweet, and across infancy report using snacks to manage behavior, underscoring the importance of providing parents with guidance on healthy snacking during the first year of life.
