RESUMEN

Body dissatisfaction is a key factor contributing to the development of disordered eating, and body dissatisfaction is often influenced by media, peer, and parental pressures during adolescence. Little research has explored ways in which parents can help their children manage pressures from social media and their peers. The present study used the MyVoice National Poll of Youth, a large text-message cohort of young people (14-24 years old) in the United States, to collect and examine qualitative data about their experiences with parental weight-related communication and how they think parents can best support their children regarding messages they see/hear surrounding weight, body shape and size by their peers and media sources. 801 participants responsed to at least one question. Results from the present study suggest that young people want their parents to model healthy relationships with food and their body, teach body neutrality/acceptance, and normalize all body types. Findings suggest that there are many proactive, practical approaches parents can adopt to help support their children and offset weight-related pressures from other sources.

RESUMEN

INTRODUCTION: Individuals with obesity who smoke cigarettes have increased risk of morbidity and mortality. The goal of the current study was to inform the development of a multiple health behavior change intervention designed to facilitate smoking cessation while also targeting weight gain. METHODS: Four qualitative focus groups were conducted with individuals who smoked cigarettes and had overweight or obesity (n = 16) to explore the combined effects of smoking and obesity, past attempts to quit smoking or lose weight, and preferences for a combined health intervention. RESULTS: Focus groups converged on five themes including: the interactive effects of weight and smoking; lack of experience with evidence-based weight loss approaches; a desire and expectation to lose weight quickly; rapid weight gain during past attempts at smoking cessation; and interest in a multiple health behavior change intervention with weight management preceding smoking cessation and an emphasis on planning for the future and receiving encouragement and support. CONCLUSIONS: Groups provided insight into key topics to highlight in a combined intervention and key issues that have interfered with success in both domains.

RESUMEN

National estimates suggest that more than 35% of American children, ages 2-19 years, are overweight or obese, which increases their risk for weight-related comorbidities including diabetes, cancer, cardiovascular disease risk factors, depression, and anxiety. While obesity prevention is most cost-effective, for youth with existing obesity, the United States Preventive Services Task Force recommends ≥26 h of comprehensive lifestyle intervention over 6-12 months. This include standard behavioral therapy, dietary counseling, and an emphasis on physical activity. Although such programs are effective in reducing weight status, there are many barriers to completing these programs. A novel consideration for both the prevention and treatment of childhood obesity is the recognition that the timing of intervention, both duration and time of the year, can impact family engagement and intervention effectiveness. This paper discusses the potential of targeting high-risk periods for weight gain and offering brief behavioral intervention, in hopes of inspiring research on novel approaches to the prevention and treatment of childhood obesity.

RESUMEN

BACKGROUND: Childhood obesity is a critical public health concern. One potential determinant to obesity that is less understood is food insecurity. OBJECTIVE: To examine the association of food security status on body mass index (BMI) change in a Pediatric Weight Management Intervention (PWMI) consistent with national treatment recommendations. METHODS: This analysis included 201 participants from the Healthy Weight Clinic (HWC). Using linear mixed models, we compared BMI and %BMIp95 change per year between the food insecure group and food secure group, adjusting for baseline BMI, age and sex, and SNAP enrolment. RESULTS: In fully adjusted models, children in households with food insecurity had a 0.50 (0.26-0.74) kg/m2 BMI increase per year and a 2.10 (1.02-3.19) %BMIp95 increase per year compared to households that were food secure. CONCLUSIONS: When comparing the BMI effect of the HWC between the food insecure group and food secure group, those experiencing food insecurity in the HWC had an increase in BMI compared to those with food security. These findings suggest that food insecurity may reduce the effectiveness of PWMIs consistent with national recommendations; however, more studies should be conducted to better understand this relationship.

RESUMEN

Childhood obesity is associated with negative physical and psychosocial outcomes, especially for children from low-income backgrounds. It is critical to adapt evidence-based family healthy weight programs to meet the needs of this population. The Framework for Reporting Adaptations and Modifications to Evidence-Based Interventions was used to describe the process of using qualitative data from community and intervention stakeholders, children with overweight or obesity from low-income backgrounds, and caregivers to guide adaptations to the JOIN for ME pediatric weight management intervention. Qualitative interviews were conducted with key community and intervention stakeholders (e.g., nurse care managers, prior JOIN for ME coaches; N = 21). Focus groups were conducted in both Spanish and English with children with overweight or obesity from low-income backgrounds (N = 35) and caregivers of children with overweight or obesity from low-income backgrounds (N = 71). Qualitative data analysis informed modifications including content adaptations to simplify and tailor materials, contextual adaptations to improve intervention engagement and framing, resource awareness, and modality of delivery, training adaptations, and implementation/scale-up activities to increase connections with community partners. The process of engaging multiple stakeholder perspectives to tailor an existing intervention can provide a model for future researchers to improve the potential disseminability of an intervention.


Obesity during childhood is related to a number of negative outcomes for youth, with children from low-income backgrounds at especially high risk for obesity and related negative outcomes. There is a pressing need for programs to address weight in children and families that meet the needs of families from low-income backgrounds. This study outlines adaptations made to an evidence-based family healthy weight program to increase the likelihood of dissemination in low-income communities. Interviews were conducted with community stakeholders, children with overweight or obesity from low-income backgrounds, and caregivers of children with overweight or obesity from low-income backgrounds. These interviews led to simplification and tailoring of curriculum materials, changes to framing of weight management, increased information about available resources, remote intervention delivery, and changes to scale-up activities.

RESUMEN

Objective: Lapses from the dietary prescription in lifestyle modification interventions for overweight/obesity are common and impact weight loss outcomes. While it is expected that lapses influence weight via increased consumption, there are no studies that have evaluated how dietary lapses affect dietary intake during treatment. This study examined the association between daily lapses and daily energy and macronutrient intake during a lifestyle modification intervention. Methods: This study used an intensive longitudinal design to observe participants throughout a 6-month lifestyle modification intervention. Participants (n = 32) were adults with overweight/obesity (body mass index 25-50 kg/m2) and a diagnosed cardiovascular disease risk factor (e.g., hypertension) with a desire to lose weight. Participants underwent a gold-standard individual in-person lifestyle modification protocol consisting of 3 months of weekly sessions with 3 months of monthly sessions. Each participant's dietary prescription included a calorie target range that was based on their starting weight. Participants completed ecological momentary assessment (EMA; repeated daily smartphone surveys) every other week to self-report on dietary lapses and telephone-based 24-h dietary recalls every 6 weeks. Results: On days with EMA and recalled intake (n = 210 days), linear mixed models demonstrated significant associations between daily lapse and higher total daily caloric intake (B = 139.20, p < 0.05), more daily grams of added sugar (B = 16.24, p < 0.001), and likelihood of exceeding the daily calorie goal (B = 0.89, p < 0.05). The associations between daily lapse and intake of all other daily macronutrients were non-significant. Conclusions: This study contributes to literature suggesting that dietary lapses pose a threat to weight loss success. Results indicate that reducing lapse frequency could reduce overall caloric intake and added sugar consumption.

RESUMEN

BACKGROUND: Food insecurity affects one in seven households with children in the United States, disproportionately impacts households headed by women and minorities, and is associated with childhood comorbidities, including obesity. While food insecurity likely contributes to poor health through its effect on diet, such a simplistic understanding likely obscures the effects of poverty-related stress and other Adverse Childhood Experiences, on metabolic health. METHODS: Over two summers, 100 children, ages 8-12 years, will be recruited from low-income households in an urban, Rhode Island community, to participate in an 8-week trial designed to isolate the experience of food insecurity. Summer represents a natural risk period of food insecurity in children, such that children will be randomized to receive weekly shipments of five breakfast and lunch meals that mimic school meals or to experience the likely onset of summertime food insecurity and receive a weekly newsletter on community resources that is not expected to affect food insecurity. Through assessment visits at baseline, mid-summer and end of summer, we will examine group differences in change in diet quality, biomarkers of Metabolic Syndrome, inflammation, and stress, BMI z-scores, and child measures of behavior and anxiety and depression symptoms. We will also explore the impact of caregiver mood and stress on the health effects of food insecurity. CONCLUSIONS: Findings stand to clarify the mechanisms by which food insecurity affects child health outcomes and to inform how to best address food insecurity in the context of poverty-related stress. TRIAL REGISTRATION: This trial has been registered at ClinicalTrials.gov (NCT04968496).

RESUMEN

Food on the Move is an ongoing mobile produce market program in Rhode Island whose operations evolved from previous mobile market programs evaluated by 2 research studies: (1) one on Fresh to You, a prospective cohort study evaluating markets at community sites serving low-income families; and (2) one on Live Well, Viva Bien, a cluster randomized controlled trial evaluating markets and complementary nutrition interventions at public housing sites. The 2 studies spanned more than a decade and demonstrated the effect of mobile produce markets on access to, affordability of, and consumption of fruit and vegetables in low-income communities in Rhode Island. When grant funding ended in 2016, academic and community partners continued the mobile market program as Food on the Move. The Rhode Island Public Health Institute adopted the program model and developed a business plan to maximize market efficiency. To address price as a barrier to buying fruit and vegetables, the Institute implemented an innovative incentive program for purchases made with Supplemental Nutrition Assistance Program (SNAP) benefits, funded by a federal Food Insecurity Nutrition Incentive grant program. In 2018, Food on the Move sold more than $160 000 in produce at 335 markets, more than $50 000 of which came from these SNAP incentive programs. For sustained change in communities, researchers and community partners need examples of how to translate findings from research trials into public health practice. Food on the Move serves as a case study for the successful transition of community-focused research into a sustainable and scalable evidence-based program.

RESUMEN

OBJECTIVE: To determine whether a prefilled online grocery shopping (default) cart improves the nutritional quality of groceries purchased compared with receiving nutrition education (NE). DESIGN: Longitudinal study. SETTING: Three food pantries in the US. PARTICIPANTS: Thirty-eight adults with low income. INTERVENTION: Groceries were purchased online for 5 consecutive weeks. After a baseline shopping trip, participants were randomized to receive NE or a nutritionally balanced prefilled online grocery shopping cart (ie, default cart) before shopping (from week 1 [T1] to week 4 [T4]). MAIN OUTCOME MEASURES: Diet quality (Healthy Eating Index [HEI-2015] scores), energy, and energy density of each online cart (ie, grocery purchases). ANALYSIS: Piecewise linear mixed-effects models. RESULTS: From baseline to T1, HEI-2015 scores in the default condition significantly increased (95% confidence interval [CI], 9.79-23.39), whereas total calories (95% CI, -10,942 to -1,663) and energy density (95% CI, -0.70 to -0.45) significantly decreased compared with NE. Improved HEI-2015 scores were maintained through T4. Calories and energy density increased from T1 to T4 in the default condition, but values remained lower (ie, more healthful) than the NE condition. In the NE condition, outcomes did not significantly change during the intervention. CONCLUSIONS AND IMPLICATIONS: Providing an online default cart may improve the nutritional quality of grocery purchases. However, future research is warranted to assess whether adding a second nudge later in the intervention or combining the NE and default cart further promotes healthy purchasing behavior.

RESUMEN

Advances have been made in the development of effective interventions to address pediatric obesity; however, research findings often do not translate into clinical practice and a limited number of programs have been designed toward wide-spread dissemination and implementation. The Rhode Island (RI)-Childhood Obesity Research Demonstration (CORD) 3.0 Project involves adapting and testing an evidence-based pediatric weight management intervention (PWMI), JOIN for ME, for wide-scale dissemination and implementation in communities with a high proportion of families from low-income backgrounds. In this article, we describe the robust developmental formative evaluation (FE) process employed by RI-CORD as a model for the use of FE to drive dissemination of evidence-based PWMIs. The current project was guided by the Consolidated Framework for Implementation Research and Proctor Implementation Outcomes. This article also showcases examples of how the use of key informant interviews from engaged stakeholders in the community during a developmental FE process can drive selection of implementation strategies. The use of FE, driven by evidence-based theory, can help provide a roadmap to successful implementation of a pediatric weight management program, such as JOIN for ME.

RESUMEN

PURPOSE OF REVIEW: Although the set point is one of the best understood weight defense mechanisms, how and when a set point is established and what causes its disruption are not well understood. The purpose of this review is to address these gaps in the literature by exploring studies on the establishment of the set point theory and the underlying metabolic processes that support its existence. RECENT FINDINGS: Research suggests that weight loss achieved through restricted energy intake and increased energy expenditure is difficult to maintain and is often followed by greater weight gain over time. It is hypothesized that such weight gain is driven by an individual's set point, a weight range in which the body seeks to remain by adjusting metabolism (e.g. by moderating energy expenditure based on energy intake in times of diet or energy fluctuation). Similar to adults, weight loss in adolescence results in decreased resting metabolic rate (RMR), and that the RMR remains suppressed even with weight restoration. SUMMARY: Recommending weight loss in youth results in metabolic adaptations to restore weight and weight inclusive approaches may be more appropriate to protect their health and wellbeing.

RESUMEN

OBJECTIVE: The present study was a secondary data analysis of a randomized controlled trial (RCT) to examine changes in depressive symptoms and eating-related cognitions in teens who participated in a nonclinic-based adolescent behavioral weight control treatment delivered by YMCA coaches. Differences in intervention effects were also examined by sex. METHODS: Adolescents (N = 66; 13-17 years; 60.6% girls) with overweight (10.6%) or obesity (53.0% with severe obesity) participated in an RCT comparing 2 versions of an evidence-based intervention. Adolescents completed measures of eating-related cognitions (Eating Disorder Examination Questionnaire) and depressive symptoms (Children's Depressive Inventory-2) at baseline and end of active treatment (16 weeks). RESULTS: There were no significant effects of group, time, or group by time interaction for depressive symptoms, global eating-related cognitions, dietary restraint, or eating concerns (ps > 0.05). Shape concerns (p = 0.04) and weight concerns (p = 0.02) significantly decreased over the intervention. Significant interactions between sex and time on global eating-related cognitions (p < 0.001), eating (p = 0.002), shape (p = 0.02), and weight concerns (p = 0.004) were detected such that female participants' scores decreased over the course of the treatment, but male participants' scores did not. CONCLUSION: The results demonstrate some positive and no detrimental effects of a nonclinic-based behavioral weight control intervention on adolescents' eating-related cognitions and depressive symptoms. The findings may mitigate concerns that dissemination of structured, nonclinic-based weight management programs for adolescents will produce negative eating and mood outcomes; however, replication of results in larger trials is needed.

RESUMEN

OBJECTIVES: Behavioral obesity treatment (BOT) produces clinically significant weight loss and health benefits for many individuals with overweight/obesity. Yet, many individuals in BOT do not achieve clinically significant weight loss and/or experience weight regain. Lapses (i.e., eating that deviates from the BOT prescribed diet) could explain poor outcomes, but the behavior is understudied because it can be difficult to assess. We propose to study lapses using a multi-method approach, which allows us to identify objectively-measured characteristics of lapse behavior (e.g., eating rate, duration), examine the association between lapse and weight change, and estimate nutrition composition of lapse. METHOD: We are recruiting participants (n = 40) with overweight/obesity to enroll in a 24-week BOT. Participants complete biweekly 7-day ecological momentary assessment (EMA) to self-report on eating behavior, including dietary lapses. Participants continuously wear the wrist-worn ActiGraph Link to characterize eating behavior. Participants complete 24-hour dietary recalls via structured interview at 6-week intervals to measure the composition of all food and beverages consumed. RESULTS: While data collection for this trial is still ongoing, we present data from three pilot participants who completed EMA and wore the ActiGraph to illustrate the feasibility, benefits, and challenges of this work. CONCLUSION: This protocol will be the first multi-method study of dietary lapses in BOT. Upon completion, this will be one of the largest published studies of passive eating detection and EMA-reported lapse. The integration of EMA and passive sensing to characterize eating provides contextually rich data that will ultimately inform a nuanced understanding of lapse behavior and enable novel interventions.Trial registration: Registered clinical trial NCT03739151; URL: https://clinicaltrials.gov/ct2/show/NCT03739151.

RESUMEN

BACKGROUND: Behavioral lifestyle intervention (BLI) is recommended as a first-line treatment for obesity. While BLI has been adapted for online delivery to improve potential for dissemination while reducing costs and barriers to access, weight losses are typically inferior to gold standard treatment delivered in-person. It is therefore important to refine and optimize online BLI in order to improve the proportion of individuals who achieve a minimum clinically significant weight loss and mean weight loss. STUDY DESIGN: Five experimental intervention components will be tested as adjuncts to an established 12-month online BLI: virtual reality for BLI skills training, interactive video feedback, tailored intervention to promote physical activity, skills for dysregulated eating, and social support combined with friendly competition. Following the Multiphase Optimization Strategy (MOST) framework, the components will first be refined and finalized during Preparation Phase pilot testing and then evaluated in a factorial experiment with 384 adults with overweight or obesity. A priori optimization criteria that balance efficacy and efficiency will be used to create a finalized treatment package that produces the best weight loss outcomes with the fewest intervention components. Mediation analysis will be conducted to test hypothesized mechanisms of action and a moderator analysis will be conducted to understand for whom and under what circumstances the interventions are effective. CONCLUSION: This study will provide important information about intervention strategies that are useful for improving outcomes of online BLI. The finalized treatment package will be suitable for testing in a future randomized trial in the MOST Evaluation Phase.

RESUMEN

BACKGROUND: Gastrointestinal symptoms (GIS) are common after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). However, little is known about frequencies of GIS and their co-occurrence with risky eating behaviors. OBJECTIVES: Compare RYGB and SG on GIS and risky eating behaviors, and test associations between GIS and behaviors. SETTING: Two university hospitals in Northeastern United States. METHODS: RYGB (n = 18) and SG (n = 53) patients completed smartphone-based ecological momentary assessment of GIS and risky eating behaviors at 4 semi-random times daily for 10 days preoperatively and at 3, 6, and 12 months postoperatively. Study objectives were evaluated using generalized linear mixed-effects models. RESULTS: All available data from each assessment were included in the analysis: participant attrition was 18%, 30%, and 38% at 3, 6, and 12 months. All GIS were reduced at 12 months postoperative. Bloating decreased consistently whereas cramping, dehydration, and dumping first increased at 3 to 6 months then decreased to 12 months. Diarrhea, nausea, reflux, and vomiting decreased to 12 months for RYGB, but first increased at 3 to 6 months then decreased to 12 months for SG. Consumption of carbonated and sugar-sweetened beverages, fatty meats, and sweets decreased to 6 months then rebounded at 12 months. Eating past the first sign of fullness, drinking liquids with meals, not starting meals with protein, and fried foods consumption decreased to 6 months and then rebounded for RYGB only at 12 months. Alcohol consumption did not change. Sweets consumption and eating past the first sign of fullness were most consistently associated with GIS for both RYGB and SG patients. CONCLUSION: GIS and risky eating behaviors improved postoperatively, although patterns of change were variable and occasionally differed between RYGB and SG. Pending replication, patients may benefit from intervention to limit risky behaviors that are tailored to their surgery type.

RESUMEN

BACKGROUND: Children from racial and ethnic minority groups, low-income households, and those with overweight or obesity gain more weight during the summer than the school year. Summer day camps, which offer routine opportunities for physical activity and regular meal and snack times, have potential to mitigate excess weight gain. This randomized controlled trial was done to determine the feasibility and preliminary effectiveness of summer camp in preventing excess summer weight gain among youth from low-income households. METHODS: Children, ages 6 to 12 years, were randomized to attend 8-weeks of summer day camp (CAMP) or to experience an unstructured summer as usual (SAU) in 2017-2018. Primary feasibility outcomes included retention, engagement and completion of midsummer measures. Secondary outcomes included changes in BMIz, engagement in moderate to vigorous physical activity (MVPA) and sedentary behavior, and diet quality and energy intake from the school year to summer. Multivariable linear mixed models were used to assess group differences. RESULTS: Ninety-four participants were randomized to CAMP (n = 46) or SAU (n = 48), of whom 93.0 and 91.6% completed end of school and end of summer assessments, respectively. While CAMP participants attended only 50% of camp days offered, on average, they lost - 0.03 BMIz units while those in SAU gained 0.07 BMIz units over the summer (b = 0.10; p = .02). Group differences in change in energy intake from the school year to summer were borderline significant, as energy intake remained relatively unchanged in CAMP participants but increased among participants in SAU (p = 0.07). CONCLUSIONS: Randomizing children to attend summer day camp or experience an unstructured summer as usual was effective in this low-income sample. Our findings support the potential for summer camps in mitigating excess summer weight gain. A larger randomized trial is needed explore efficacy, cost-effectiveness and longer-term effects of attending summer camp on weight and weight-related behaviors.

RESUMEN

Excess consumption of highly processed foods may be associated with lower diet quality and obesity prevalence, but few studies have examined these relationships in children from low-income households. Therefore, the objective of this study was to evaluate the relationship between food consumption by processing category, diet quality as measured by the Healthy Eating Index-2015 (HEI-2015) and body mass index (BMI) in a sample of low-income children. Data from a study assessing the impact of Summer Food Service participation on diet quality and weight status (N = 131) was used to conduct a cross-sectional analysis of children aged six to twelve years from low-income communities in the Northeastern U.S. Total HEI-2015 score and percentage of calories consumed by processing level were computed per day from three 24-h diet recalls. Multivariable linear regression was used to assess the relationship between percentage of calories from foods by processing category (unprocessed and minimally, basic, moderately and highly processed), HEI-2015 and BMI-z score. The final sample was 58% male and 33.8% obese. On average, children consumed 39.8 ± 17.2% of calories from highly processed foods. A 10% increase in calories consumed from highly processed foods was associated with a 2.0 point decrease in total HEI-2015 score [95% CI (-2.7, -1.2)], and a 10% increase in calories from minimally processed foods was associated with a 3.0 increase in HEI-2015 score [95% CI (2.1, 3.8)]. Relationships between processing level and BMI-z score were not significant. Among this sample of low-income children, greater intake of highly processed foods was associated with lower dietary quality, but not weight status. Future research should explore prospective associations between food consumption by processing category and weight status in children.

RESUMEN

OBJECTIVE: To determine how children interpret terms related to food processing; whether their categorisation of foods according to processing level is consistent with those used in research; and whether they associate the degree of processing with healthfulness. DESIGN: Qualitative data were collected from ten focus groups. Focus groups were audio-recorded, transcribed verbatim, and thematic analysis was conducted. SETTING: Four elementary and afterschool programmes in a large, urban school district in the USA that served predominantly low-income, racial/ethnic minority students. PARTICIPANTS: Children, 9-12 years old, in the fourth-sixth grades (n 53). RESULTS: The sample was 40 % male, 47 % Hispanic with a mean age of 10·4 ± 1·1 years. Children's understanding of unprocessed foods was well aligned with research classifications, while concordance of highly processed foods with research categorisations varied. Five primary themes regarding the way children categorised foods according to their processing level emerged: type and amount of added ingredients; preparation method; packaging and storage; change in physical state or sensory experience; and growing method. Most children associated processing level with healthfulness, describing unprocessed foods as healthier. The most common reason provided for the unhealthfulness of processed foods was added ingredients, including 'chemicals' and 'sugar'. CONCLUSIONS: The current study demonstrated that children have a working knowledge of processing that could be leveraged to encourage healthier eating patterns; however, their understanding is not always consistent with the classification systems used in research. The vocabulary used by researchers and consumers to talk about processing must be reconciled to translate findings into actionable messages.

RESUMEN

We recently reported that a 12-week internet weight loss program produced greater weight losses than education control in overweight/obese people living with HIV (PLWH) (4.4 kg vs 1.0 kg; p < 0.05). This manuscript presents the changes in diet, physical activity, behavioral strategies, and cardio-metabolic parameters. Participants (N = 40; 21 males, 19 females) were randomly assigned to an internet behavioral weight loss (WT LOSS) program or internet education control (CONTROL) and assessed before and after the 12-week program. Compared to CONTROL, the WT LOSS arm reported greater use of behavioral strategies, decreases in intake (- 681 kcal/day; p = 0.002), modest, non-significant, increases in daily steps (+ 1079 steps/day) and improvements on the Healthy Eating Index. There were no significant effects on cardio-metabolic parameters. The study suggests that a behavioral weight loss program increases the use of behavioral strategies and modestly improves dietary intake and physical activity in PLWH. Further studies with larger sample sizes and longer follow-up are needed.Clinical Trials Registration: NCT02421406.

RESUMEN

Background. Parent-aimed guidance on the topic of processed foods may help limit highly processed foods in children's diets, but little is known about parent understanding and perceptions of these products. Aims. To determine how parent perceptions of processing align with processing classification systems used in research, and to identify opportunities for future research in communicating information about processed foods. Method. Six focus groups with lower income, racial/ethnic minority and immigrant parents of fourth to sixth graders (n = 37) were conducted. Parents were asked to discuss their views on terminology related to food processing, classification of foods according to their processing level, the healthfulness of select foods, and criteria for choosing snacks for their children. Focus groups were guided by a thematic approach. NVivo 12 (QSR International) was used to facilitate analyses. Results. Thirty mothers and seven fathers participated. Two thirds (62%) were foreign-born; 38% identified as Hispanic. The term "processing" lacked consistent meaning among parents, with variation by immigrant status. Participants associated highly processed foods with convenience, packaging, and added ingredients; "less-processed" versions of foods (e.g., fresh; homemade) were perceived as healthier. Children's preferences were the main criteria for choosing snacks. Foreign-born parents were more likely to associate processed foods with positive characteristics (e.g., properly cooked). Conclusion. The concept of food processing is an area of misconception among parents, providing an opportunity for education that may be extended to larger audiences. A universally accepted definition of food classification by processing level is necessary to effectively communicate the link between processing and healthfulness.
