RESUMEN

Unhealthy diets are a major impediment to achieving a healthier population in the United States. Although there is a relatively clear sense of what constitutes a healthy diet, most of the US population does not eat healthy food at rates consistent with the recommended clinical guidelines. An abundance of barriers, including food and nutrition insecurity, how food is marketed and advertised, access to and affordability of healthy foods, and behavioral challenges such as a focus on immediate versus delayed gratification, stand in the way of healthier dietary patterns for many Americans. Food Is Medicine may be defined as the provision of healthy food resources to prevent, manage, or treat specific clinical conditions in coordination with the health care sector. Although the field has promise, relatively few studies have been conducted with designs that provide strong evidence of associations between Food Is Medicine interventions and health outcomes or health costs. Much work needs to be done to create a stronger body of evidence that convincingly demonstrates the effectiveness and cost-effectiveness of different types of Food Is Medicine interventions. An estimated 90% of the $4.3 trillion annual cost of health care in the United States is spent on medical care for chronic disease. For many of these diseases, diet is a major risk factor, so even modest improvements in diet could have a significant impact. This presidential advisory offers an overview of the state of the field of Food Is Medicine and a road map for a new research initiative that strategically approaches the outstanding questions in the field while prioritizing a human-centered design approach to achieve high rates of patient engagement and sustained behavior change. This will ideally happen in the context of broader efforts to use a health equity-centered approach to enhance the ways in which our food system and related policies support improvements in health.

RESUMEN

INTRODUCTION: Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders, but few studies have evaluated mortality risks among individuals with IBS. We explored the association between IBS and all-cause and cause-specific mortality in the UK Biobank. METHODS: We included 502,369 participants from the UK Biobank with mortality data through 2022. IBS was defined using baseline self-report and linkage to primary care or hospital admission data. We estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause and cause-specific mortality using multivariable Cox proportional hazards regression models within partitioned follow-up time categories (0-5, >5-10, and >10 years). RESULTS: A total of 25,697 participants (5.1%) had a history of IBS at baseline. After a median follow-up of 13.7 years, a total of 44,499 deaths occurred. Having an IBS diagnosis was strongly associated with lower risks of all-cause (HR = 0.70, 95% CI = 0.62-0.78) and all-cancer (HR = 0.69, 95% CI = 0.60-0.79) mortality in the first 5 years of follow-up. These associations were attenuated over follow-up, but even after 10 years of follow-up, associations remained inverse (all-cause: HR = 0.89, 95% CI = 0.84-0.96; all-cancer: HR = 0.87, 95% CI = 0.78-0.97) after full adjustment. Individuals with IBS had decreased risk of mortality from breast, prostate, and colorectal cancers in some of the follow-up time categories. DISCUSSION: We found that earlier during follow-up, having diagnosed IBS was associated with lower mortality risk, and the association attenuated over time. Additional studies to understand whether specific factors, such as lifestyle and healthcare access, explain the inverse association between IBS and mortality are needed.

RESUMEN

BACKGROUND: Food insecurity and metabolic diseases both disproportionately affect Hispanic children. Cross-sectional studies have linked food insecurity with adverse cardiometabolic markers, including elevated plasma triglycerides and glucose concentrations. However, the association between changes in food insecurity and changes in cardiometabolic markers in children remains to be explored. Furthermore, few studies have assessed the impact of school-based nutrition interventions on household food insecurity. OBJECTIVE: The objectives of this study are to assess the effect of the TX Sprouts intervention on household food insecurity and to examine the association between changes in household food insecurity and changes in cardiometabolic markers over 1 academic year. METHODS: This secondary analysis used data from TX Sprouts, a cluster-randomized school-based gardening, cooking, and nutrition trial. The study enrolled 3rd-5th-grade students from 16 schools that served primarily (>50%) Hispanic families with low income in Austin, TX. Participants (n = 619) provided household food insecurity data and fasting lipid panels at both baseline and postintervention, ∼9 mo following. RESULTS: There was no intervention effect on household food insecurity. Independent of the intervention, a 1-point increase in food insecurity, indicative of becoming more food insecure, was associated with a 2.61 mg/dL increase in triglycerides (P = 0.001; 95% CI: 1.04, 4.19) at follow-up. Children who were food insecure at baseline and became food secure at follow-up had a mean 5.05 mg/dL decrease in triglycerides compared with a 7.50 mg/dL increase in triglycerides in children who remained food insecure throughout (95% CI: -23.40, -1.71, P = 0.023). There were no other associations between changes in food insecurity and cardiometabolic markers. CONCLUSION: Although the intervention did not improve food insecurity, reductions in food insecurity over 9 mo were associated with improved cardiometabolic markers in high-risk children, emphasizing the need for interventions targeting food insecurity. The study is registered at clinicaltrials.gov under NCT02668744 (https://classic. CLINICALTRIALS: gov/ct2/show/NCT02668744).

RESUMEN

BACKGROUND: Schools are a key setting for supporting youth physical activity, given their broad reach and diverse student populations. Organizational readiness is a precursor to the successful implementation of school-based physical activity opportunities. The R = MC2 heuristic (Readiness = Motivation x Innovation-Specific Capacity x General Capacity) describes readiness as a function of an organization's motivation and capacity to implement an innovation and can be applied to better understand the implementation process. The purpose of this study was to explore the barriers to and facilitators of implementing school-based physical activity opportunities in the context of organizational readiness. METHODS: We analyzed interview data from 15 elementary school staff (principals, assistant principals, physical education teachers, and classroom teachers) from a school district in Texas. We focused on factors related to adopting, implementing, and sustaining a variety of school-based physical activity opportunities. We used the Framework Method to guide the analysis and coded data using deductive (informed by the R = MC2 heuristic) and inductive approaches. Themes were generated using the frequency, depth, and richness of participant responses. RESULTS: Four themes emerged from the data: (1) implementation is aided by the presence of internal and external relationships; (2) physical activity opportunities compete with other school priorities; (3) seeing the benefits of physical activity opportunities motivates school staff toward implementation; and (4) staff buy-in is critical to the implementation process. Themes 1-3 aligned with subcomponents of the R = MC2 heuristic (intra- and inter-organizational relationships, priority, and observability), whereas Theme 4 (staff buy-in) related to multiple subcomponents within the Motivation component but was ultimately viewed as a distinct construct. CONCLUSION: Our results highlight and explain how key readiness constructs impact the implementation of school-based physical activity opportunities. They also highlight the importance of obtaining staff buy-in when implementing in the school setting. This information is critical to developing readiness-building strategies that help schools improve their capacity to deliver physical activity opportunities effectively. TRIAL REGISTRATION: Not applicable.

RESUMEN

Partnerships between food prescription programs and food banks can address food insecurity and support health; however, few studies have examined the experience and perceptions of health care partners about these programs. Our objective was to analyze secondary qualitative data from clinicians and clinic staff involved in implementing a food prescription program in Houston, Texas. We collected data from 17 health care clinics from May 2018 through March 2021 to learn how implementation of the food prescription program was perceived, and we received 252 responses. Principal themes were the importance of a value-based care strategy, patient and food pantry barriers to success, the importance of interorganizational care coordination, and the need to integrate food prescriptions into clinic workflow. Insights of clinicians and clinic staff on implementation of food prescription programs can inform program development and dissemination.

RESUMEN

INTRODUCTION: US school systems underwent major upheaval, including closures, implementation of virtual and/or hybrid learning, and stringent infection mitigation protocols, during the initial phase of the COVID-19 pandemic. We aimed to examine the association between food insecurity and perceived health, perceived stress, and social determinants of health concerns among elementary schoolteachers serving predominantly low-income children during the COVID-19 pandemic. METHODS: Brighter Bites, a nonprofit organization that weekly distributes fresh fruits and vegetables and nutrition education materials to more than 300 schools serving racial and ethnic minority populations with low income, conducts annual surveys of participating teachers to help determine subsequent efforts to support schools and families during the school year. We analyzed self-reported data collected electronically by the Brighter Bites teachers survey in 76 elementary schools during summer 2020. We used generalized linear mixed models to measure the association between food insecurity and health-related concerns. RESULTS: Of 862 teachers who responded to the survey, 685 answered the 2 questions about food insecurity status; of these, 199 (29.1%) reported experiencing food insecurity. Food insecurity was positively associated with poor perceived general health, greater perceived stress, concerns about various social determinants of health, and changes in fruit and vegetable consumption during the COVID-19 pandemic. CONCLUSION: Our study demonstrated the high prevalence of food insecurity and highlights its associated factors among elementary schoolteachers during the COVID-19 pandemic. It calls attention to the high correlation of various concerns among elementary schoolteachers during the COVID-19 pandemic. Further intervention and policy efforts are needed to relieve food insecurity-related concerns and enhance well-being among teachers.

RESUMEN

OBJECTIVE: Poor metabolic health and unhealthy lifestyle factors have been associated with risk and severity of COVID-19, but data for diet are lacking. We aimed to investigate the association of diet quality with risk and severity of COVID-19 and its interaction with socioeconomic deprivation. DESIGN: We used data from 592 571 participants of the smartphone-based COVID-19 Symptom Study. Diet information was collected for the prepandemic period using a short food frequency questionnaire, and diet quality was assessed using a healthful Plant-Based Diet Score, which emphasises healthy plant foods such as fruits or vegetables. Multivariable Cox models were fitted to calculate HRs and 95% CIs for COVID-19 risk and severity defined using a validated symptom-based algorithm or hospitalisation with oxygen support, respectively. RESULTS: Over 3 886 274 person-months of follow-up, 31 815 COVID-19 cases were documented. Compared with individuals in the lowest quartile of the diet score, high diet quality was associated with lower risk of COVID-19 (HR 0.91; 95% CI 0.88 to 0.94) and severe COVID-19 (HR 0.59; 95% CI 0.47 to 0.74). The joint association of low diet quality and increased deprivation on COVID-19 risk was higher than the sum of the risk associated with each factor alone (Pinteraction=0.005). The corresponding absolute excess rate per 10 000 person/months for lowest vs highest quartile of diet score was 22.5 (95% CI 18.8 to 26.3) among persons living in areas with low deprivation and 40.8 (95% CI 31.7 to 49.8) among persons living in areas with high deprivation. CONCLUSIONS: A diet characterised by healthy plant-based foods was associated with lower risk and severity of COVID-19. This association may be particularly evident among individuals living in areas with higher socioeconomic deprivation.

RESUMEN

BACKGROUND: Little is known about the extent to which severe maternal morbidity (SMM) at delivery impacts early and late postpartum readmission. OBJECTIVES: We examined readmission rates for women with and without SMM (and their 18 subtypes) at delivery and characterised the most common medical reasons for readmissions. METHODS: We conducted a retrospective cohort study utilising the 2016-2017 Nationwide Readmissions Database among women giving births in the United States. Deliveries were classified according to the presence or absence of 18 SMM indicators defined by the Centers for Disease Control and Prevention using the International Classification of Diseases, Tenth Edition, Clinical Modification (ICD-10-CM) diagnosis and procedure codes. The primary outcome of this study was all-cause early (≤7 day) and late (8 to 42 day) postpartum readmission. Survey-weighted Poisson regression with robust error variance was used to generate adjusted risk ratios (RR) and 95% confidence intervals (CI) to investigate the association between SMM and early and late postpartum readmission. Additionally, we compared principal diagnoses codes during readmission hospitalisations among women with and without SMM at delivery. RESULTS: Of the 6 193 852 women examined, 4.9% (n = 4928) with any SMM and 1.4% (n = 83 995) with no SMM were readmitted within 42 days after delivery. After adjusting for obstetric co-morbidities and sociodemographic factors, women with any SMM were 57% (RR 1.57, 95% CI 1.47, 1.67) more likely to have an early readmission and 69% (RR 1.69, 95% CI 1.57, 1.82) more likely to have a late readmission compared to women with no SMM at delivery. However, the risk was attenuated when excluding women with blood transfusion only. Women with and without SMM were readmitted predominantly for obstetric complications and infections. CONCLUSIONS: Women with SMM at delivery were more likely to experience both early and late postpartum readmission, independent of their obstetrical co-morbidity burden and sociodemographic factors.

RESUMEN

INTRODUCTION: Food insecurity affects dietary behaviors and diet quality in adults. This relationship is not widely studied among early care and education (ECE) providers, a unique population with important influences on children's dietary habits. Our study's objective was to explore how food insecurity affected diet quality and dietary behaviors among ECE providers. METHODS: We used baseline data from a cluster-randomized controlled trial (January 2019-December 2020) on 216 ECE providers under the Pennsylvania Head Start Association. We used radar plots to graph scores for the Healthy Eating Index 2015 and the Alternative Healthy Eating Index (AHEI) 2010 and fitted a multivariate regression model for diet quality measures, adjusting for covariates. RESULTS: Among the 216 participants, 31.5% were food insecure. ECE providers who were food insecure had a lower AHEI-2010 mean score (mean difference for food insecure vs food secure = -4.8; 95% CI, -7.8 to -1.7; P = .002). After adjusting for covariates, associations remained significant (mean difference = -3.9; 95% CI, -7.5 to -0.4; P = .03). Food insecure ECE providers were less likely to use nutrition labels (22.8% vs 39.1%; P = .046) and more likely to report cost as a perceived barrier to eating fruits and vegetables. CONCLUSION: We found a significant inverse association between food insecurity and the AHEI-2010 diet quality score among ECE providers after adjusting for covariates. More studies are needed to examine the effects of food insecurity on dietary behaviors of ECE providers and their response to nutrition education programs targeting their health.

RESUMEN

PURPOSE: Increased cardiovascular disease and second cancer risks among childhood cancer survivors (CCS) makes them and their families important audiences for nutrition intervention. Family meals and home cooking practices have been associated with improved diet and health, but there is a gap in the literature on understanding these behaviors and their motivating values among CCS families. This study qualitatively explores family meal values and behaviors in a sample of CCS parent-child dyads. METHODS: This observational and qualitative study recruited a convenience sample of 11 parent-CCS dyads. Data collection included audio and video recording of food preparation events in participant homes, which were analyzed with an inductive coding technique to examine meal-related values in CCS families. RESULTS: Analyses revealed four major categories of meal values. Effort, including time and difficulty, as well as budget, healthfulness, and family preferences emerged as recurrent values impacting meal preparation. These values were impacted by the cancer experience upon diagnosis, during treatment, and into survivorship. CONCLUSIONS: A better understanding of CCS family meal planning values, the impact of the cancer experience on these values, and the inclusion of CCS in food preparation reveals potential intervention targets, facilitators, and barriers for future interventions to improve dietary behaviors among CCS.

RESUMEN

OBJECTIVE: Survival rates for paediatric cancers have increased dramatically since the 1970s, but childhood cancer survivors (CCS) are at increased risk for several chronic diseases throughout life. Nutrition interventions promoting healthy family meals may support wellness for survivors, but little research has explored CCS family food preparation habits. The goal of the present study was to describe and compare food preparation practices of CCS and non-CCS families. DESIGN: Observational. SETTING: Typical evening meal preparation events were observed and recorded in participant homes. Recordings and notes were analysed using the Healthy Cooking Index (HCI), a measure of nutrition-optimizing food preparation practices relevant to survivor wellness. Demographics, BMI and nutrient composition of prepared meals were also collected. PARTICIPANTS: Forty parents with a CCS or non-CCS child aged 5-17 years were recruited. RESULTS: There were no major differences between the CCS and non-CCS families with regard to summative HCI score or specific food preparation behaviours. Meals prepared by CCS and non-CCS families had similar nutrient compositions. CONCLUSIONS: The study revealed areas for practical nutrition intervention in CCS and non-CCS families. Future studies should consider adopting and tailoring nutrition intervention methods that have been successful in non-CCS communities.

RESUMEN

INTRODUCTION: Little is known about the social needs of low-income households with children during the coronavirus-2019 (COVID-19) pandemic. Our objective was to conduct a cross-sectional quantitative and qualitative descriptive analysis of a rapid-response survey among low-income households with children on social needs, COVID-19-related concerns, and diet-related behaviors. METHODS: We distributed an electronic survey in April 2020 to 16,435 families in 4 geographic areas, and 1,048 responded. The survey asked families enrolled in a coordinated school-based nutrition program about their social needs, COVID-19-related concerns, food insecurity, and diet-related behaviors during the pandemic. An open-ended question asked about their greatest concern. We calculated descriptive statistics stratified by location and race/ethnicity. We used thematic analysis and an inductive approach to examine the open-ended comments. RESULTS: More than 80% of survey respondents were familiar with COVID-19 and were concerned about infection. Overall, 76.3% reported concerns about financial stability, 42.5% about employment, 69.4% about food availability, 31.0% about housing stability, and 35.9% about health care access. Overall, 93.5% of respondents reported being food insecure, a 22-percentage-point increase since fall 2019. Also, 41.4% reported a decrease in fruit and vegetable intake because of COVID-19. Frequency of grocery shopping decreased and food pantry usage increased. Qualitative assessment identified 4 main themes: 1) fear of contracting COVID-19, 2) disruption of employment status, 3) financial hardship, and 4) exacerbated food insecurity. CONCLUSION: Our study highlights the compounding effect of the COVID-19 pandemic on households with children across the spectrum of social needs.

RESUMEN

Clostridioides difficile spores can survive in the environment in either mono- or mixed-species biofilms. However, no previous studies have investigated chemical disinfection of C. difficile spores embedded in biofilms. Thus, the purpose of this study was to assess the in vitro effectiveness of hospital disinfectants against C. difficile spores embedded within biofilms. Five unique C. difficile strains embedded in three different biofilm types grown for 72 or 120 h were exposed to seven different hospital disinfectants. C. difficile abundance [as log(number of CFU/milliliter)] was calculated after manufacturer-determined contact times along with biofilm biomass and microscopy. The primary analysis compared differences between C. difficile vegetative cell and spore counts as well as amounts of biomass after exposure to disinfectants. C. difficile vegetative cells and spores were recovered from biofilms regardless of the type of biofilm growth or biofilm growth time. No disinfectant was able to completely eliminate C. difficile from the biofilms. Overall, Clorox, ortho-phthalaldehyde (OPA), and Virex were most effective at killing C. difficile spores regardless of biofilm age, ribotype, or wash conditions (whether biofilms are washed or unwashed) (P = 0.001, each). Clorox and OPA were also effective at killing total vegetative cell growth (P = 0.001, each), but Virex was found to be ineffective against vegetative cell growth in biofilms (P = 0.77). Clorox and Virex were most effective in reducing biomass, followed by Nixall, OPA, and Vital Oxide. No disinfectant was able to completely eliminate C. difficile embedded within biofilms although differences among disinfectants were noted. Future research will be required to determine methods to eradicate this persister reservoir.

RESUMEN

BACKGROUND: The risk of neural tube defect (NTD)-affected pregnancies is reduced with adequate folic acid intake during early pregnancy. However, NTDs have been observed among offspring of women with adequate folic acid intake. Some of these women are possibly not absorbing enough folic acid. Because lactase deficiency can lead to poor nutrient absorption, we hypothesized that lactase-deficient women will be at increased risk of having offspring with NTDs. OBJECTIVE: We examined the association between maternal rs4988235 (a lactase deficiency genetic marker) and NTDs in offspring. METHODS: We conducted a case-control study using data from the National Birth Defects Prevention Study, United States, 1997-2009, restricting to non-Hispanic white (NHW) and Hispanic women. Cases were women with an offspring with an NTD (n = 378 NHW, 207 Hispanic), and controls were women with an offspring without a birth defect (n = 461 NHW, 165 Hispanic). Analyses were conducted separately by race/ethnicity, using logistic regression. Women with the CC genotype were categorized as being lactase deficient. To assess potential effect modification, analyses were stratified by lactose intake, folic acid supplementation, dietary folate, and diet quality. RESULTS: Among NHW women, the odds of being lactase deficient were greater among cases compared with controls (OR: 1.37; 95% CI: 1.02, 1.82). Among Hispanic women, the odds of being lactase deficient were significantly lower among cases compared with controls (OR: 0.50, 95% CI: 0.33, 0.77). The association differed when stratified by lactose intake in NHW women (higher odds among women who consumed ≥12 g lactose/1000 kcal) and by dietary folate in Hispanic women (opposite direction of associations). The association did not differ when stratified by folic acid supplementation or diet quality. CONCLUSIONS: Our findings suggest that maternal lactase deficiency is associated with NTDs in offspring. However, we observed opposite directions of effect by race/ethnicity that could not be definitively explained.

RESUMEN

A food waste problem coexists with food insecurity and obesity. Brighter Bites, a school-based food cooperative program, successfully channels primarily donated produce to low-income communities and provides nutrition education, creating an increased demand for and intake of fruits and vegetables. We present the framework used in Brighter Bites and results of operationalizing this framework during 3 years of implementation in Houston, Texas. Results demonstrated that, during 2013 through 2016, more than 12,500 families enrolled in Brighter Bites for 16 weeks in the school year. More than 90% of the produce was donated. Each week, families received on average 54 to 61 servings of fresh produce with the average cost of produce being $2.53 per family per week. Of those parents who completed the process surveys, more than 80% reported the produce to be effective in improving their children's diet. Brighter Bites demonstrates a successful model to address food waste and improve dietary habits of underserved families.

RESUMEN

INTRODUCTION: Practices and barriers to promoting healthy eating and physical activity at Head Start centers may influence children's energy balance behaviors. We examined differences between directors' and teachers' perspectives on best practices and barriers to promoting healthy eating and physical activity in Head Start centers. METHODS: We conducted a cross-sectional study of directors (n = 23) and teachers (n = 113) at 23 Head Start centers participating in the baseline assessment of the Texas Childhood Obesity Research Demonstration study. Participants completed surveys about practices and barriers to promoting healthy eating and physical activity. Multilevel regression models examined differences between director and teacher responses. RESULTS: More than half of directors and teachers reported meeting most best practices related to nutrition and physical activity; few directors or teachers (<25%) reported conducting physical activity for more than 60 minutes a day, and less than 40% of teachers helped children attend to satiety cues. Significantly more directors than teachers reported meeting 2 nutrition-related best practices: "Teachers rarely eat less healthy foods (especially sweets, salty snacks, and sugary drinks) in front of children" and "Teachers talk to children about trying/enjoying new foods" (P < .05). No barrier to healthy eating or physical activity was reported by more than 25% of directors or teachers. Significantly more teachers than directors reported barriers to healthy eating, citing lack of food service staff support, limited time, and insufficient funds (P < .05). CONCLUSION: More barriers to healthy eating were reported than were barriers to physical activity indicating that more support may be needed for healthy eating. Differences between responses of directors and teachers may have implications for future assessments of implementation of best practices and barriers to implementation related to nutrition and physical activity in early care and education centers.

RESUMEN

BACKGROUND: Lunches that parents pack for their young children to eat at school or the Early Care and Education (ECE) center fall short of recommended standards. Lunch is in the Bag is a multi-level behavioral nutrition intervention to increase parents' packing of fruit, vegetables, and whole grains in their children's lunches. Designed for implementation in ECE centers, the five-week long intervention is followed three months later with a one-week booster. METHODS: Efficacy of Lunch is in the Bag was tested in cluster randomized trial. Participants were 633 families from 30 ECE centers (15 intervention, 15 control) across Austin, San Antonio, and Houston, Texas, USA. Primary outcomes were servings of fruit, vegetables, and whole grains observed in the children's parent-packed bag lunches. Servings of refined grains, meats/beans/eggs/nuts, dairy, chips, and sweets also were observed. Data were collected at baseline, post-intervention (6-week follow-up), pre-booster (22-weeks follow-up), and post-booster (28-week follow-up). Time-by-treatment interactions were analyzed separately for each of the food groups using multi-level models to compare changes from baseline. Analyses were adjusted for relevant demographic variables and clustering within centers and parents. RESULTS: The intervention effected increases from baseline to 6-week follow-up in vegetables (0.17 servings, SE = 0.04, P < 0.001) and whole grains (0.30 servings, SE = 0.13, P = 0.018). The increase in whole grains was maintained through the 28-week follow-up (0.34 servings, SE = 0.13, P = 0.009). Fruit averaged more than 1.40 servings with no differences between groups or across time. The intervention prevented increase in sweets (-0.43 servings, SE = 0.11, P < .001, at the 22-week follow-up). Parents persisted, however, in packing small amounts of vegetables (averages of 0.41 to 0.52 servings) and large amounts of sweets and chips (averages of 1.75 to 1.99 servings). CONCLUSIONS: The need for and positive effects of the Lunch is in the Bag intervention at ECE centers where parents send bag lunch for their preschool-aged children was confirmed. An important direction for future research is discovery of more options for leveraging the partnership of ECE centers and families to help young children learn to eat and enjoy vegetables and other healthy foods in preference to less healthy choices such as chips and sweets. TRIAL REGISTRATION: The Clinical Trials Number is NCT01292434 .

RESUMEN

The purpose of this study was to evaluate the effectiveness of a new school-based food co-op program, Brighter Bites (BB), to increase fruit and vegetable intake, and home nutrition environment among low-income 1st graders and their parents. This was a non-randomized controlled comparative effectiveness trial (2013-2015). Six schools received BB (n=407 parent-child dyads); six comparison schools implemented a coordinated school health program (n=310 parent-child dyads) in Houston, Texas, 2013-2015. Brighter Bites (BB) is a 16-week school-based food co-op comprising weekly distribution of fresh produce (50 servings); nutrition education in schools and for parents; and weekly recipe tastings. Measurements included parent-reported home nutrition environment surveys, and food frequency questionnaires for parent and child. Intervention effects were examined using multivariate analyses. At baseline, the sample was 71% Hispanic, 24% African American; 43% of 1st graders were overweight/obese. Children receiving BB had significant increases in intake of fruit servings (P=0.046), vegetable servings (P=0.049), and decreased intake of added sugars (P=0.014). Among parents, there were significant increases in fruit consumed (P=0.032); vegetable intake increased baseline to midpoint but not post-intervention. Among BB families, there were significant improvements in the home environment including understanding and usage of nutrition facts labels to make food purchases (P<0.05), frequency of cooking (P=0.007), rules and practices regarding eating family meals (P=0.022), serving fruits (P=0.005) and vegetables (P=0.028) at meals, and limiting portion sizes (P=0.016). In conclusion, a school-based food co-op model shows promising results in improving dietary habits and home nutrition environment among low-income families.

RESUMEN

OBJECTIVE: To evaluate the effectiveness of the parent- and early care education (ECE) center-based Lunch is in the Bag program on communication between parent, child, and their ECE center providers around fruits, vegetables and whole grain foods (FVWG). METHOD: A total of n=30 ECE center; 577 parent-child dyads participated in this group-randomized controlled trial conducted from 2011 to 2013 in Texas (n=15 ECE center, 327 dyads intervention group; n=15 ECE center, 250 dyads comparison group). Parent-child and parent-ECE center provider communication was measured using a parent-reported survey administered at baseline and end of the five-week intervention period. Multilevel linear regression analysis was used to compare the pre-to-post intervention changes in the parent-child and parent-ECE center provider communication scales. Significance was set at p<0.05. RESULTS: At baseline, parent-child and parent-ECE center provider communication scores were low. There was a significant increase post-intervention in the parent-ECE center provider communication around vegetables (Adjusted ß=0.78, 95%CI: 0.13, 1.43, p=0.002), and around fruit (Adjusted ß=0.62, 95%CI: 0.04, 0.20, p=0.04) among the parents in the intervention group as compared to those in the comparison group. There were no significant intervention effects on parent-child communication. CONCLUSION: Lunch is in the Bag had significant positive effects on improving communication between the parents and ECE center providers around FVWG.

RESUMEN

Across multiple sectors, organizational readiness predicts the success of program implementation. However, the factors influencing readiness of early childhood education (ECE) organizations for implementation of new nutrition and physical activity programs is poorly understood. This study presents a new conceptual framework to measure organizational readiness to implement nutrition and physical activity programs in ECE centers serving children aged 0 to 5 years. The framework was validated for consensus on relevance and generalizability by conducting focus groups; the participants were managers (16 directors and 2 assistant directors) of ECE centers. The framework theorizes that it is necessary to have "collective readiness," which takes into account such factors as resources, organizational operations, work culture, and the collective attitudes, motivation, beliefs, and intentions of ECE staff. Results of the focus groups demonstrated consensus on the relevance of proposed constructs across ECE settings. Including readiness measures during program planning and evaluation could inform implementation of ECE programs targeting nutrition and physical activity behaviors.
