RESUMO

BACKGROUND: Snacking is nearly universal and contributes significant energy to U.S. children's diets. Little is known, however, about where and when snacking intake occurs and if such patterns change with age. This research evaluated age-related differences in eating location, food source location, and timing of snacking among U.S. children aged 1-19 years (y). METHODS: A cross-sectional analysis of snacking among 14,666 children in the 2007-2018 U.S. National Health and Nutrition Examination Survey was conducted using a single 24-hour dietary recall. Snacking was participant-defined and included all eating occasions outside of meals. Linear regression and analysis of covariance were used to examine the effects of age (toddler 1-2 y, preschooler 3-5 y, school-age 6-11 y, adolescent 12-19 y) on the percentage of daily snack energy consumed by eating location (at home vs. away from home), food source location (grocery store, convenience store, school/childcare, restaurant, from someone else (i.e. "socially"), and other), and time of day (morning, 6am-12pm; early afternoon, 12pm-3pm; late afternoon/afterschool 3pm-6pm; evening 6pm-9pm, late-night 9pm-12am, and overnight 12am-6am). RESULTS: On average, U.S. children consumed most of their daily snacking energy at home (71%), from foods and beverages obtained from grocery stores (75%), and in the late afternoon/afterschool (31%). Toddlers and preschoolers consumed a greater percentage of their daily snack energy during the morning hours compared to school-age children and adolescents (both p < 0.001); school-age children consumed the most in the evening (27%, p < 0.001), and adolescents consumed the most in the late-night period (22%, p < 0.001). Age-related increases were seen in the percentage of daily snacking energy eaten outside the home (p < 0.001), and obtained socially (p < 0.001), from restaurants (p < 0.001), and convenience stores (p < 0.001). CONCLUSION: Findings reveal age-related differences in eating location, food source location, and timing of snack intake among U.S. children aged 1-19 y. Younger children consume a greater percentage of snacking calories in the morning and at home relative to older children. School-age children and adolescents show greater snacking in the evening and at night and from foods obtained and eaten outside the home. Efforts to promote healthy snacking behaviors among children should consider developmental differences in snacking patterns.

RESUMO

BACKGROUND: Small-quantity lipid-based nutrient supplements (SQ-LNS) are designed to address undernutrition during the complementary feeding period. SQ-LNS contains added sugars, but limited research has assessed whether infants' acceptance varies between versions with and without sugars. OBJECTIVES: Our objective was to examine the effects of repeated exposure on children's acceptance of sweetened and unsweetened SQ-LNS. We aimed to understand caregivers' perceptions of children's liking of the 2 SQ-LNS versions and their influences on infant acceptance of SQ-LNS. METHODS: Caregivers (86% non-Hispanic White) and children (7-24 mo), participated in a randomized, 2-week home-exposure study and baseline and post-home exposure assessments. Children were randomized to receive sweetened or unsweetened SQ-LNS versions, mixed with infant oatmeal. At in-person visits, caregivers fed both SQ-LNS versions to children and rated their child's liking for each. Caregivers fed the SQ-LNS version to which their child was randomized until the child refused to eat more. Acceptance was measured as total grams consumed. Mixed-effects linear models tested the change in SQ-LNS consumed between baseline and postexposure by the SQ-LNS version and number of home exposures. Covariates included the amount of SQ-LNS consumed at baseline, child BMI z-score, child age, and breastfeeding experience. RESULTS: Children's acceptance of both SQ-LNS versions increased from baseline to postexposure (ß, 0.71 g; 95% CI: 0.54-0.89 g; P = 0.04), regardless of SQ-LNS version (P = 0.88) or number of home exposures (P = 0.55). Caregivers rated children's liking of unsweetened SQ-LNS higher at baseline (P = 0.02). Children with lower liking ratings at baseline showed the greatest increases in acceptance between baseline and postexposure (P = 0.01). CONCLUSIONS: Children's acceptance of SQ-LNS increased with repeated exposure, whether offered the sweetened or unsweetened version, providing preliminary support that adding sugar to SQ-LNS may not improve acceptance in young children. Children who initially like the supplement less may need repeated experience to learn to accept SQ-LNS. This trial was registered at clinicaltrials.gov as NCT04544332.

RESUMO

BACKGROUND: The home environment is a central and modifiable influence on the development of childhood obesity. Evidence supports the central role of parents in shaping problematic child eating behaviors and excess weight. Most studies of feeding emphasize parent-driven influences without taking into account the child's role in eating interactions. Few studies have addressed the bi-directional nature of feeding dynamics in studies of young children. METHODS: The goals of this study were: 1) to examine if parental feeding styles during preschool (4-5 years) predict child weight status at 7-9 years, and 2) to examine the direction of effects between parental feeding styles and child weight status over time. Participants were part of a larger longitudinal study of Hispanic Head Start families living in the West South Central United States. Data from mother/child dyads were collected at three time points: Time 1 (ages 4-5), Time 2 (ages 5 ½-6 ½), and at Time 3 (ages 7-9). Only data from the Times 1 and 3 were used in the current analyses. A total of 128 mothers and their children had data on all variables needed for the analyses. Assessments included parent-reported feeding styles, feeding practices, acculturation, child eating behaviors, and child height and weight. Hierarchical regression was used to examine the first aim; a cross-lagged panel analysis examined the second aim. RESULTS: An indulgent parental feeding style at ages 4-5 was associated with increased child BMI z-score at ages 7-9. Indulgent feeding significantly contributed to child BMI z-score beyond demographics, baseline child BMI z-score, parental acculturation, and child eating behaviors. Regarding the direction of effects in parental feeding interactions, the cross-lagged analyses showed that both indulgent feeding style and authoritative feeding style at Time 1 positively predicted child BMI z-scores at Time 3. Child effects were significant as well. Child BMI z-score at Time 1 positively predicted indulgent feeding and negatively predicted authoritarian feeding at Time 3. CONCLUSIONS: Indulgent feeding should be addressed in future family-focused childhood obesity initiatives focused on young children and their parents.

RESUMO

OBJECTIVE: Snacking among preschool aged children is nearly universal and has been associated with overconsumed nutrients, particularly solid fats and added sugars (SoFAS). This research examined caregivers' schemas, or cognitive frameworks, for offering snacks to preschool-aged children. METHODS: A qualitative design utilizing card sort methods was employed. Participants were 59 Black, Hispanic, and White caregivers of children aged 3-5 years with low-income backgrounds. Caregivers sorted 63 cards with images of commonly consumed foods/beverages by preschool-aged children in three separate card sorts to characterize snacking occasions, purposes, and contexts. The mean SoFAS content (kcal/100 g) of foods/beverages was evaluated by snacking occasions (snacks vs. not-snacks), purposes, and contexts. RESULTS: Just under two-thirds (38/63 food cards) of foods/beverages were classified as snacks with moderate to high agreement. Snacks were offered for non-nutritive (e.g., requests, rewards) and nutritive (e.g., hunger/thirst) purposes in routine (e.g., home, school) and social contexts (e.g., with grandparents). Snacks offered for non-nutritive purposes and in social contexts were higher in SoFAS than those offered for nutritive reasons and in routine contexts. CONCLUSIONS: Caregivers of young children offered various types of foods/beverages as snacks, with higher SoFAS snacks given for non-nutritive purposes and in social contexts. Understanding of caregivers' schemas for offering snacks to young children may inform targets for obesity prevention and anticipatory guidance to promote the development of healthful eating behaviors.

RESUMO

Objectives. To identify the effect of a Breakfast in the Classroom (BIC) initiative on the foods and drinks students consume in the morning.Methods. Sixteen public schools in Philadelphia, Pennsylvania, that provide universal breakfast participated in a group randomized trial to examine the effects of BIC with complementary nutrition promotion between 2013 and 2016. Control schools (n = 8) offered breakfast in the cafeteria before school. Baseline data were collected from 1362 students in grades 4 to 6. Endpoint data were collected after 2.5 years. Students self-reported the foods and drinks they consumed in the morning.Results. At endpoint, there was no effect of the intervention on breakfast skipping. Nearly 30% of intervention students consumed breakfast foods or drinks from multiple locations, as compared with 21% of control students. A greater proportion of intervention students than control students consumed 100% juice, and a smaller proportion consumed sugar-sweetened beverages and foods high in saturated fat and added sugar.Conclusions. A BIC initiative led to improvements in the types of foods and drinks students consumed in the morning. However, the program did not reduce breakfast skipping and increased the number of locations where students ate.

RESUMO

OBJECTIVE: Economic hardship (EH) may link to poorer child diet, however whether this association is due to resource limitations or effects on family functioning is unknown. This study examines whether parenting stress mediates the association between EH and child consumption of foods high in saturated fats and added sugars (SFAS). DESIGN: Data were collected from the Fragile Families and Child Wellbeing study. EH was assessed using eight items collected when children were between 1-9 years old. Mothers reported parenting stress and frequency of child consumption of high SFAS foods when children were 9 years old. Latent growth curve modelling (LGCM) and structural equation modelling tested direct associations between the starting level/rate of change in EH and high SFAS food consumption, and parenting stress as a mediator of the association. SETTING: Twenty US cities. PARTICIPANTS: Mothers/children (n 3846) followed birth through age 9 years, oversampled 'high-risk', unmarried mothers. RESULTS: LGCM indicated a curvilinear trend in EH from ages 1-9, with steeper increases from ages 3-9 years. EH did not directly predict the frequency of high SFAS foods. Average EH at 3 and 5 years and change in EH from ages 1-9 predicted higher parenting stress, which in turn predicted more frequent consumption of high SFAS foods. CONCLUSIONS: Findings suggest it may be important to consider parenting stress in early prevention efforts given potential lasting effects of early life EH on child consumption of high SFAS foods. Future research should explore how supports and resources may buffer effects of EH-related stress on parents and children.

RESUMO

To prevent childhood obesity it is critical to identify behavioral phenotypes for overeating, especially among children who are predisposed to obesity. We examined caloric compensation and appetite control in 212 normal-weight (NW) and obese (OB) children, ages 7 to 9, who were at high risk (HR) or low risk (LR) for obesity based on maternal obesity. In a within-subjects crossover design, children ate breakfast, lunch, dinner, and snacks in the laboratory once a week for two weeks. Children's percentage compensation index (%COMPX) was computed at breakfast. Twenty-five minutes before breakfast, children received one of two compulsory preloads, which varied in energy density (ED) and caloric content [Low ED (LED): 1.00 kcal/g; 100 kcal; High ED (HED): 1.60 kcal/g; 160 kcal]. Children's appetite was measured hourly using Visual Analog Scales, which were used to compute 3-h post-prandial area under the curve (AUCs) after breakfast and the satiety quotient (SQ), which allows between-group comparisons of a fixed amount of a food's potency to reduce appetite sensations per unit of intake. There were no significant differences in %COMPX, SQ, or AUC among LR-NW, HR-NW, and HR-OB children (P > 0.10). SQs for Hunger and Prospective Consumption were higher and SQ for Fullness lower after consuming the LED compared to the HED preload (P < 0.009). Further, the SQ and AUC for Desire to Eat and AUC for Prospective Consumption significantly predicted energy intake during the remainder of the day (P < 0.03). In this study, HR-NW children did not differ from LR-NW or HR-OB children in their caloric compensation or appetite control. Foods with a high satiating effect may facilitate appetite control and help to moderate daily energy intake in all children, including at-risk children.

RESUMO

BACKGROUND: Few interventions have shown efficacy to influence key energy balance behaviors during the preschool years. OBJECTIVE: A randomized controlled trial (RCT) was used to evaluate the efficacy of Food, Fun, and Families (FFF), a 12 week authoritative food parenting intervention for mothers with low-income levels, to reduce preschool-aged children's intake of calories from solid fat and added sugar (SoFAS). METHODS: Mothers were randomly assigned to receive FFF (n = 59) or to a delayed treatment control (n = 60). The primary outcome was children's daily energy intake from SoFAS at the end of the 12 week intervention, controlling for baseline levels, assessed by 24-h dietary recalls. Secondary outcomes included children's daily energy intake, children's BMI z-scores, and meal observations of maternal food parenting practices targeted in FFF (e.g. providing guided choices). RESULTS: Participating mothers were predominantly African American (91%), with 39% educated beyond high school and 66% unemployed. Baseline demographics and child SoFAS intakes did not differ by group. Lost to follow-up was 13% and did not differ between groups. At post-intervention, FFF children consumed ~ 94 kcal or 23% less daily energy from SoFAS than children in the control group, adjusting for baseline levels (307.8 (95%CI = 274.1, 341.5) kcal vs. 401.9 (95%CI = 369.8, 433.9) kcal, FFF vs. control; p < 0.001). FFF mothers also displayed a greater number of authoritative parenting practices when observed post-intervention with their child at a buffet-style meal (Wilcoxon z = - 2.54, p = 0.012). Neither child total daily energy intake nor BMI z-scores differed between groups post-intervention. CONCLUSIONS: Findings demonstrate the initial efficacy of an authoritative food parenting intervention for families with low-income to reduce SoFAS intake in early childhood. Additional research is needed to evaluate longer-term effects on diet and growth. TRIAL REGISTRATION: Retrospectively registered at ClinicalTrials.gov : #NCT03646201.

RESUMO

Objective: Neural substrates of loss of control (LOC) eating are undercharacterized. We aimed to model intermittent access to food to elicit disinhibited eating in youth undergoing neuroimaging, given evidence that restricted food access may increase subsequent food intake via enhancing reward value of food and diminishing eating-related self-control. Methods: Participants were 18 preadolescents (aged 9-12 years) who were overweight/obese with recent LOC eating (OW-LOC; n = 6); overweight/obese with no history of LOC eating (OW-CON; n = 5); or non-overweight with no history of LOC eating (NW-CON; n = 7). Participants underwent functional magnetic resonance imaging during a simulated food restriction paradigm in which they were alternately given restricted or unrestricted access to milkshake solutions. Results: There were no significant main effects of restricted versus unrestricted access to milkshake flavors. Group main effects revealed increased activation for OW-LOC relative to OW-CON in areas related to attentional processes (right middle frontal gyrus), inhibitory control/attentional shifts (right and left cuneus), and emotion regulation (left cingulate gyrus); and for OW-LOC relative to NW-CON in areas related to response inhibition (right inferior frontal gyrus). Significant block type × group interaction effects were found for the right middle frontal gyrus, left cingulate gyrus, and left cuneus, but these appeared to be accounted for primarily by group. Discussion: There were clear group differences in neural activity in brain regions related to self-regulation during a food restriction paradigm. Elevations in these regions among OW-LOC relative to OW-CON and NW-CON, respectively, may suggest that youth with LOC eating expended more cognitive effort to regulate ingestive behavior.

RESUMO

Existing programs which aim to prevent and treat childhood obesity often do not take into account individual variation and the underlying mechanisms that impact child eating behavior. Individual differences in children's appetitive traits have been shown to appear as early as during infancy and become more pronounced as children grow older and become more exposed to the obesogenic food environment. Differences in genetic predispositions interacting with factors in children's early environment account in part for individual differences in appetitive traits. It is very likely that obesogenic eating phenotypes manifest themselves before the onset of childhood obesity. If so, identifying these phenotypes early is expected to move primary prevention strategies in a new direction and holds great potential to significantly enhance our ability to prevent childhood obesity. The aim of this narrative review is to discuss the role of behavioral phenotyping as an innovative approach for the development of more personalized obesity prevention and treatment interventions that are tailored to children's individual predispositions. We describe several examples of appetitive traits which have been linked to overeating and excess weight gain in children and thus may represent modifiable risk factors for future interventions. The review concludes with a comprehensive synthesis of opportunities for future human ingestive behavior research on identifying behavioral phenotypes for childhood obesity.

RESUMO

Although parents often report positive intentions to promote and create a healthy food environment for their children (e.g., setting limits to snacks offered), they also experience difficulties in translating these intentions into actual behaviors. In this position paper, we argue that automatic processes explain an important part of the gap between parents' intentions and their actual food parenting behaviors. We provide a conceptual framework in which we hypothesize that automatic effects on food parenting occur through two key interrelated constructs: habits (key outcome construct) and volitional regulation behaviors (key mediating construct). Moreover, we discuss potentially important impulse-focused techniques that may directly change habits (e.g., nudging; inhibitory control training) or indirectly through volitional regulation behaviors (e.g., implementation intentions; mental contrasting). We make use of the literature on the role of intention-behavior discordance in general health behaviors and discuss implications for food parenting practices. Our framework provides a dual process view towards food parenting and may help to explain when and why parents are likely to engage in (un)healthy food parenting behaviors. In addition, this framework may hopefully stimulate research on (combinations of old and) new techniques to promote good food parenting behaviors.

RESUMO

Large portions promote intake of energy dense foods (i.e., the portion size effect--PSE), but the neurobiological drivers of this effect are not known. We tested the association between blood oxygen level dependent (BOLD) brain response to food images varied by portion size (PS) and energy density (ED) and children's intake at test-meals of high- and low-ED foods served at varying portions. Children (N = 47; age 7-10 years) participated in a within-subjects, crossover study consisting of 4 meals of increasing PS of high- and low-ED foods and 1 fMRI to evaluate food images at 2 levels of PS (Large, Small) and 2 levels of ED (High, Low). Contrast values between PS conditions (e.g., Large PS - Small PS) were calculated from BOLD signal in brain regions implicated in cognitive control and reward and input as covariates in mixed models to determine if they moderated the PSE curve. Results showed a significant effect of PS on intake. Responses to Large relative to Small PS in brain regions implicated in salience (e.g., ventromedial prefrontal cortex and orbitofrontal cortex) were positively associated with the linear slope (i.e., increase in intake from baseline) of the PSE curve, but negatively associated with the quadratic coefficient for the total meal. Responses to Large PS High ED relative to Small PS High ED cues in regions associated with cognitive control (e.g., dorsolateral prefrontal cortex) were negatively associated with the linear slope of the PSE curve for high-ED foods. Brain responses to PS cues were associated with individual differences in children's susceptibility to overeating from large portions. Responses in food salience regions positively associated with PSE susceptibility while activation in control regions negatively associated with PSE susceptibility.

RESUMO

BACKGROUND: Universal access to the School Breakfast Program (SBP) is intended to help low-income and food-insecure students overcome barriers to eating breakfast. However, SBP participation is often still low despite universal access. Further information is needed with regard to these children's breakfast behaviors, and in particular breakfast behaviors among youth from food-insecure families, to inform effective breakfast interventions. OBJECTIVES: The objective of this study was to examine breakfast behaviors among a large sample of urban students with universal access to the SBP and to identify differences in breakfast behaviors among children from food-secure compared with food-insecure households. METHODS: A cross-sectional study of 821 fourth- through sixth-grade students and their parents from 16 schools was conducted. Students reported the foods/drinks selected and location of obtaining food/drink on the morning of data collection, parents reported household food security status using the 6-item Food Security Survey Module, and the school district provided SBP participation data during the fall semester of 2013. Multivariable linear regression models accounting for school-level clustering were used to examine differences in breakfast behaviors across 3 levels of household food security: food secure, low food secure, and very low food secure. RESULTS: Students participated in the SBP 31.2% of possible days, with 13% never participating in the SBP. One-fifth (19.4%) of students purchased something from a corner store for breakfast, and 16.9% skipped breakfast. Forty-six percent of students were food insecure; few differences in breakfast behaviors were observed across levels of food security. CONCLUSIONS: Despite universal access to the SBP, participation in the SBP is low. Breakfast skipping and selection of foods of low nutritional quality in the morning are common, regardless of household food security status. Additional novel implementation of the SBP and addressing students' breakfast preferences may be necessary to further reduce barriers to students obtaining a free, healthful breakfast. This trial was registered at clinicaltrials.gov as NCT01924130.

RESUMO

Few studies have examined direct effects of food cues presented within television (TV) programs on eating behavior in adults. This research experimentally determined whether exposure to food cues in TV programs affects energy intake during TV viewing among young women, independently from food cues presented in TV advertisements. The experiment involved a 2 (TV program with or without food cues) by 2 (TV advertisements with or without food cues) between-participants design. While watching TV, participants could freely eat peanut chocolate candies and crisps (potato chips). Participants were 121 young women (mean age = 19.6 years; mean BMI = 22.5). Participants who watched a TV program with food cues tended to have a lower total energy intake and ate significantly less peanut chocolate candies than participants who watched the same TV program without food cues. This effect was particularly pronounced among participants with a higher BMI. Food advertisements did not affect energy intake. Findings may indicate that subtle continuous food cues during TV programs could make young females more aware of their own eating and/or weight, leading to reduced intake of particularly sweet snack foods during TV viewing. Considering the non-significant trend for the effect of the TV program with food cues on total energy intake, findings should be replicated to provide possible tools for prevention campaigns using food cue reminders to watch one's intake.

RESUMO

BACKGROUND: Snacking contributes to excessive energy intakes in children. Yet factors shaping child snacking are virtually unstudied. This study examines food parenting practices specific to child snacking among low-income caregivers. METHODS: Semi-structured interviews were conducted in English or Spanish with 60 low-income caregivers of preschool-aged children (18 non-Hispanic white, 22 African American/Black, 20 Hispanic; 92% mothers). A structured interview guide was used to solicit caregivers' definitions of snacking and strategies they use to decide what, when and how much snack their child eats. Interviews were audio-recorded, transcribed verbatim and analyzed using an iterative theory-based and grounded approach. A conceptual model of food parenting specific to child snacking was developed to summarize the findings and inform future research. RESULTS: Caregivers' descriptions of food parenting practices specific to child snacking were consistent with previous models of food parenting developed based on expert opinion [1, 2]. A few noteworthy differences however emerged. More than half of participants mentioned permissive feeding approaches (e.g., my child is the boss when it comes to snacks). As a result, permissive feeding was included as a higher order feeding dimension in the resulting model. In addition, a number of novel feeding approaches specific to child snacking emerged including child-centered provision of snacks (i.e., responding to a child's hunger cues when making decisions about snacks), parent unilateral decision making (i.e., making decisions about a child's snacks without any input from the child), and excessive monitoring of snacks (i.e., monitoring all snacks provided to and consumed by the child). The resulting conceptual model includes four higher order feeding dimensions including autonomy support, coercive control, structure and permissiveness and 20 sub-dimensions. CONCLUSIONS: This study formulates a language around food parenting practices specific to child snacking, identifies dominant constructs, and proposes a conceptual framework to guide future research.

RESUMO

Assessing parent affect is important because studies examining the parent-child dyad have shown that parent affect has a profound impact on parent-child interactions and related outcomes. Although some measures that assess general affect during daily lives exist, to date there are only few tools that assess parent affect in the context of feeding. The aim of this study was to develop an instrument to measure parent affect specific to the feeding context and determine its validity and reliability. A brief instrument consisting of 20 items was developed that specifically asks how parents feel during the feeding process. This brief instrument draws on the structure of a well-validated general affect measure. A total of 296 Hispanic and Black Head Start parents of preschoolers completed the Feeding Emotions Scale along with other parent-report measures as part of a larger study designed to better understand feeding interactions during the dinner meal. Confirmatory factor analysis supported a two-factor model with independent subscales of positive affect and negative affect (Cronbach's alphas of 0.85 and 0.84, respectively). Concurrent and convergent construct validity was evaluated by correlating the subscales of the Feeding Emotions Scale with positive emotionality and negative emotionality from the Differential Emotions Scale - a measure of general adult emotions. Concurrent and convergent criterion validity was evaluated by testing mean differences in affect across parent feeding styles using ANOVA. A significant difference was found across maternal weight status for positive feeding affect. The resulting validated measure can be used to assess parent affect in studies of feeding to better understand how interactions during feeding may impact the development of child eating behaviors and possibly weight status.

RESUMO

Until now, the literatures on the effects of food parenting practices and parents' own dietary behavior on children's dietary behavior have largely been independent from one another. Integrating findings across these areas could provide insight on simultaneous and interacting influences on children's food intake. In this narrative review, we provide a conceptual model that bridges the gap between both literatures and consists of three main hypotheses. First, parental dietary behavior and food parenting practices are important interactive sources of influence on children's dietary behavior and Body Mass Index (BMI). Second, parental influences are importantly mediated by changes in the child's home food environment. Third, parenting context (i.e., parenting styles and differential parental treatment) moderates effects of food parenting practices, whereas child characteristics (i.e., temperament and appetitive traits) mainly moderate effects of the home food environment. Future studies testing (parts of) this conceptual model are needed to inform effective parent-child overweight preventive interventions.

RESUMO

BACKGROUND: Increasing school breakfast participation has been advocated as a method to prevent childhood obesity. However, little is known about children's breakfast patterns outside of school (e.g., home, corner store). Policies that increase school breakfast participation without an understanding of children's breakfast habits outside of school may result in children consuming multiple breakfasts and may undermine efforts to prevent obesity. The aim of the current study was to describe morning food and drink consumption patterns among low-income, urban children and their associations with relative weight. METHODS: A cross-sectional analysis was conducted of data obtained from 651 4th-6th graders (51.7% female, 61.2% African American, 10.7 years) in 2012. Students completed surveys at school that included all foods eaten and their locations that morning. Height and weight were measured by trained research staff. RESULTS: On the day surveyed, 12.4% of youth reported not eating breakfast, 49.8% reported eating one breakfast, 25.5% reported eating two breakfasts, and 12.3% reported eating three or more breakfasts. The number of breakfasts consumed and BMI percentile showed a significant curvilinear relationship, with higher mean BMI percentiles observed among children who did not consume any breakfast and those who consumed ≥ 3 breakfasts. Sixth graders were significantly less likely to have consumed breakfast compared to younger children. A greater proportion of obese youth had no breakfast (18.0%) compared to healthy weight (10.1%) and overweight youth (10.7%, p = .01). CONCLUSIONS: When promoting school breakfast, policies will need to be mindful of both over- and under-consumption to effectively address childhood obesity and food insecurity.

RESUMO

Policies represent a key opportunity to improve the health outcomes of populations, and if implemented well, can reduce disparities affecting marginalized populations. Many policies are only evaluated on whether they elicit their intended health outcome. However, a lack of understanding regarding if and how they are implemented may hinder the intended impact overall and on addressing health disparities. Implementation science offers an array of frameworks and methodological approaches for assessing policy delivery, yet few examples exist that meaningfully include health equity as a core focus. This commentary describes the importance of equity-informed implementation measurement by providing case examples and implications for assessment. In addition, we highlight examples of emerging work in policy implementation grounded in health equity with suggested steps for moving the field forward. The ultimate goal is to move toward open-access measurement approaches that can be adapted to study implementation of a variety of policies at different stages of implementation, driven by input from marginalized populations and implementation practitioners, to move the needle on addressing health disparities.


This article talks about the need to include health equity as a major focus when understanding if and how policies are being implemented. We talk about gaps in the implementation science field and how equity-informed measurement tools can help to bridge this gap. Finally, we give some examples of efforts in place and where others can add to the growing resources to improve policy delivery.
