Infant embodied requests and teacher-practitioner offers during early childhood education mealtimes.

The importance of building healthy relationships with food in children's early years is of paramount importance. Building on prior work exploring the social and linguistic practices in infant eating interaction experiences, this research uses a multimodal conversation analysis approach to explore how mealtime interactions are managed as a co-constructed activity between infants (0-2 years) and early childhood teacher-practitioners. Here we will explore video data recorded during mealtimes in an early childhood setting in Mid-Wales, where infants orient to recruitments for assistance and teachers provide offers of help with food items throughout the data. Analysis demonstrates 1) infant recruitment of help through embodied 'showing' an item causing a problem in multimodal ways, initiating joint attention that mobilises an offer from an adult in the shape of 'do you want me to X' and 2) adult initiation of an offer of help in the shape of 'would you like me to X' that are not prompted by infants 'showing' an item. Such practices demonstrate infant social competence in recruiting assistance through multimodal resources, and adult's noticings that help is required and their initiation of provision of assistance. The detailed exploration into the ways in which mealtimes are a collaboratively achieved experience reveals how infants effectively contribute in resourceful ways, and how teacher-practitioner responses frame mealtimes as co-produced activities.

A theoretical explanation for how a nutrition counseling and medically tailored meal delivery program benefitted participants living with lung cancer.

PURPOSE: The purpose of this study was to assess participants' perceptions and experiences while participating in a Food is Medicine medically tailored meal plus intensive nutrition counseling intervention to create a theoretical explanation about how the intervention worked. METHODS: This interpretive qualitative study included the use of semi-structured interviews with active participants in a randomized controlled trial aimed at understanding how a medically tailored meal plus nutrition counseling intervention worked for vulnerable individuals with lung cancer treated at four cancer centers across the USA. During the 8-month long study, participants in the intervention arm were asked to be interviewed, which were recorded, transcribed verbatim, and analyzed using conventional content analysis with principles of grounded theory. RESULTS: Twenty individuals participated. Data analysis resulted in a theoretical explanation of the intervention's mechanism of action. The explanatory process includes three linked and propositional categories leading to patient resilience: engaging in treatment, adjusting to diagnosis, and active coping. The medically tailored meals plus nutrition counseling engaged participants throughout treatment, which helped participants adjust to their diagnosis, leading to active coping through intentional self-care, behavior change, and improved quality of life. CONCLUSIONS: These findings provide evidence that a Food is Medicine intervention may buffer some of the adversity related to the diagnosis of lung cancer and create a pathway for participants to experience post-traumatic growth, develop resilience, and change behaviors to actively cope with lung cancer. Medically tailored meals plus intensive nutrition counseling informed by motivational interviewing supported individuals' adjustment to their diagnosis and resulted in perceived positive behavior change.

"Just sit and eat." Adult and Child Mealtime Responsibilities in Early Care and Education Centers During COVID-19 in Florida.

Most young children in the United States attend early care and education (ECE) programs, in which they eat 3-4 times daily. 'Division of responsibility' between adult and child means the adults are responsible for what, when and where, and the child is responsible for whether, what and how much to eat. A balanced division of responsibility can support children's development of healthy eating competency. This paper aims to describe division of responsibility during mealtimes during COVID-19 in Florida using a cross-sectional, mixed methods design. Questions were developed based on Trust Model and Social Cognitive Theory. A survey was completed by 759 ECE directors and 431 teachers, and 29 teachers completed in-depth interviews. COVID-19 increased teacher mealtime responsibilities. Most (95%+) ECE teachers provided meals at the same time and place daily (when and where). Children determined what and how much they ate, but did not serve or handle food. Implications include modifying mealtime routines to minimize the risk of COVID-19 and support healthy eating with a balanced division of responsibility.

Mealtime best practices and infection control in early care and education centres during COVID-19.

BACKGROUND: Most young children in the United States attend early care and education (ECE) programmes, where they consume the majority of daily calories. Best practices to support children's healthy eating include teachers sitting together with children, eating the same food, and appropriately supporting children in serving and feeding themselves. To understand how the COVID-19 pandemic changed mealtime practices in ECE, this study (1) describes what adaptations ECE directors and teachers made to mealtimes to include best practices, and (2) identifies common adaptations made to comply with COVID-19 infection control guidelines. METHODS: This cross-sectional, mixed-methods study utilized survey and interview questions based on the trust model and social cognitive theory. More than 7000 surveys were distributed to ECE directors and teachers in Florida. Surveys were completed by 759 directors and 431 teachers. Also, 29 follow-up interviews with teachers were completed. Participants were asked to describe their mealtimes before and during COVID-19. Descriptive statistics and frequencies were used to analyse survey data, and thematic analysis was applied to interview data. RESULTS: Less than 5% of survey respondents reported children serving themselves, a pre-COVID best practice. Interviews identified three common adaptations: (1) modification-best practices were incorporated into new routines, such as eating together but sitting farther away, (2) elimination-routines changed so that best practices were no longer possible, such as teachers wearing masks and standing during meals, and (3) minimal change-minimal changes due to COVID-19 occurred and consequently mealtime practices did not change. CONCLUSIONS: Current recommendations do not allow children to self-serve, which previously was a key best practice. ECE centres that have successfully integrated COVID-19 modifications and maintained mealtime best practices-perhaps in a new form-can serve as examples for others. These findings are generalizable to ECE centres in Florida and could be compared with other states.

Meal Patterns and Food Choices of Female Rats Fed a Cafeteria-Style Diet Are Altered by Gastric Bypass Surgery.

After Roux-en-Y gastric bypass surgery (RYGB), rats tend to reduce consumption of high-sugar and/or high-fat foods over time. Here, we sought to investigate the behavioral mechanisms underlying these intake outcomes. Adult female rats were provided a cafeteria diet comprised of five palatable foodstuffs varying in sugar and fat content and intake was monitored continuously. Rats were then assigned to either RYGB, or one of two control (CTL) groups: sham surgery or a nonsurgical control group receiving the same prophylactic iron treatments as RYGB rats. Post-sur-gically, all rats consumed a large first meal of the cafeteria diet. After the first meal, RYGB rats reduced intake primarily by decreasing the meal sizes relative to CTL rats, ate meals more slowly, and displayed altered nycthemeral timing of intake yielding more daytime meals and fewer nighttime meals. Collectively, these meal patterns indicate that despite being motivated to consume a cafeteria diet after RYGB, rats rapidly learn to modify eating behaviors to consume foods more slowly across the entire day. RYGB rats also altered food preferences, but more slowly than the changes in meal patterns, and ate proportionally more energy from complex carbohydrates and protein and proportionally less fat. Overall, the pattern of results suggests that after RYGB rats quickly learn to adjust their size, eating rate, and distribution of meals without altering meal number and to shift their macronutrient intake away from fat; these changes appear to be more related to postingestive events than to a fundamental decline in the palatability of food choices.

A Comparison of Total Food Intake at a Personalised Buffet in People with Obesity, before and 24 Months after Roux-en-Y-Gastric Bypass Surgery.

Long-term reductions in the quantity of food consumed, and a shift in intake away from energy dense foods have both been implicated in the potent bariatric effects of Roux-en-Y gastric bypass (RYGB) surgery. We hypothesised that relative to pre-operative assessment, a stereotypical shift to lower intake would be observed at a personalised ad libitum buffet meal 24 months after RYGB, driven in part by decreased selection of high energy density items. At pre-operative baseline, participants (n = 14) rated their preference for 72 individual food items, each of these mapping to one of six categories encompassing high and low-fat choices in combination with sugar, complex carbohydrate or and protein. An 18-item buffet meal was created for each participant based on expressed preferences. Overall energy intake was reduced on average by 60% at the 24-month buffet meal. Reductions in intake were seen across all six food categories. Decreases in the overall intake of all individual macronutrient groups were marked and were generally proportional to reductions in total caloric intake. Patterns of preference and intake, both at baseline and at follow-up appear more idiosyncratic than has been previously suggested by verbal reporting. The data emphasise the consistency with which reductions in ad libitum food intake occur as a sequel of RYGB, this being maintained in the setting of a self-selected ad libitum buffet meal. Exploratory analysis of the data also supports prior reports of a possible relative increase in the proportional intake of protein after RYGB.

Sleep and circadian rhythms: pillars of health-a Keystone Symposia report.

The human circadian system consists of the master clock in the suprachiasmatic nuclei of the hypothalamus as well as in peripheral molecular clocks located in organs throughout the body. This system plays a major role in the temporal organization of biological and physiological processes, such as body temperature, blood pressure, hormone secretion, gene expression, and immune functions, which all manifest consistent diurnal patterns. Many facets of modern life, such as work schedules, travel, and social activities, can lead to sleep/wake and eating schedules that are misaligned relative to the biological clock. This misalignment can disrupt and impair physiological and psychological parameters that may ultimately put people at higher risk for chronic diseases like cancer, cardiovascular disease, and other metabolic disorders. Understanding the mechanisms that regulate sleep circadian rhythms may ultimately lead to insights on behavioral interventions that can lower the risk of these diseases. On February 25, 2021, experts in sleep, circadian rhythms, and chronobiology met virtually for the Keystone eSymposium "Sleep & Circadian Rhythms: Pillars of Health" to discuss the latest research for understanding the bidirectional relationships between sleep, circadian rhythms, and health and disease.

Afternoon distraction: a high-saturated-fat meal and endotoxemia impact postmeal attention in a randomized crossover trial.

BACKGROUND: Saturated-fat intake and endotoxemia can impair cognition. However, their acute impact on cognitive performance is unknown. OBJECTIVE: This study assessed the impact of 2 high-fat meals and endotoxemia on attention. METHODS: In this double-blind, randomized crossover trial, 51 women (n = 32 breast cancer survivors, n = 19 noncancer controls; mean ± SD age: 53 ± 8 y) completed the Continuous Performance Test (CPT) and had their blood drawn to assess endotoxemia markers LPS binding protein (LBP), soluble CD14 (sCD14), and the LBP to sCD14 ratio 1 h prior to eating either a high-saturated-fat meal or a high-oleic-sunflower-oil meal. Women again completed the CPT 5 h postmeal. At 1 to 4 wk later, women completed the same protocol but consumed the other meal. RESULTS: In adjusted models, women had more difficulty distinguishing target stimuli from distractors after consuming the high-saturated-fat meal than they did after the oleic-sunflower-oil meal (B = 4.44, SE = 1.88, P = 0.02). Women with higher baseline LBP had less consistent response times (B = 0.002, SE = 0.0008, P = 0.04). Those with higher LBP and LBP:sCD14 were less able to sustain their attention throughout the entire CPT, as reflected by their progressively slower (B = 0.002, SE = 0.0006, P = 0.003; and B = 2.43, SE = 0.090, P = 0.008, respectively) and more erratic (B = 0.003, SE = 0.0008, P < 0.0001; and B = 3.29, SE = 1.17, P = 0.006, respectively) response times. Additionally, women with higher baseline LBP or sCD14 were less able to maintain or increase response speeds at higher interstimulus intervals (B = 0.002, SE = 0.0006, P = 0.02; and B = 0.006, SE = 0.003, P = 0.03, respectively), indicating greater difficulty adapting to changing task demands. Significant meal type by LBP and LBP:sCD14 interactions emerged (P < 0.05), such that high LBP and LBP:sCD14 erased between-meal cognitive differences, uniformly impairing performance. CONCLUSIONS: These results suggest that higher LBP, sCD14, and LBP:sCD14 and saturated-fat intake individually and jointly influence attention. Endotoxemia may override the relative cognitive benefit of healthier oil choices.This trial is registered at clinicaltrials.gov as NCT04247763.

Meal-related difficulties and weight loss in older people: Longitudinal data from MAPT study.

BACKGROUND: Difficulties with meal-related activities (preparing meals and food shopping) may influence food intake, and contribute to nutritional risk among elderly people. All known studies on this topic had a cross-sectional design, thereby no causal relationships could be derived. We aim to investigate if difficulties with meal-related activities can contribute to subsequent weight loss in community-dwelling older people. METHODS: We used data of older subjects from the MAPT Study (n = 1531, median age = 74 years, 64% women), who provided prospective data on weight every 6 months and cognitive, physical condition, and functional capacities every year during a 3-year period. Difficulties preparing meals and shopping were evaluated each year with the Alzheimer's Disease Cooperative Study-Activities of Daily Living Prevention Instrument (ADCS ADL-PI) Scale. The risk of losing weight (≥5% or ≥ 3 kg in the following year) was estimated using a time-dependent Cox regression model. RESULTS: During the 3-year follow-up, a total of 851 subjects experienced at least a 5% or 3 kg weight loss. Two hundred thirty-seven subjects declared having difficulties with meal preparation at least once, and 133 declared having difficulties shopping. Subjects reporting any meal-related difficulties were older (p < 0.001), had more depressive symptoms (p < 0.001), and a lower physical function (p < 0.001) compared to those without difficulties. They also had a lower cognitive score (preparing meals: p < 0.001; shopping: p = 0.005) and a lower body mass index (preparing meals: p = 0.005; shopping: p = 0.023) at the end of the study. Meal-related activities were not associated with weight loss in unadjusted analysis and after adjustment for sex, age, depression, physical and cognitive status. CONCLUSION: Difficulties preparing meals and shopping had no effect on weight loss in community-dwelling older people, despite their association with advanced age, functional decline, and depressive symptoms.

Sharing is Caring: A Study of Food-Sharing Practices in Australian Early Childhood Education and Care Services.

Food connects people, and can significantly impact the physical, social and emotional development of young children. Food sharing and family-style mealtimes can support healthy eating practices and psychological well-being among young children, and carersother than family members, such as Early Childhood Education and Care staff, play an important role in the provision of these practices. Despite increasing numbers of Australian children attending Early Childhood Education and Care services, there is often reluctance among staff to promote such mealtime practices, to the detriment of children's social and emotional development. The aim of this paper was to focus on the potential role of Early Childhood Education and Care services in facilitating food sharing and family-style mealtime practices in the earliest stages of the lifespan. A qualitative, netnographic approach was used, and data was collected as part of the broader 'Supporting Nutrition for Australian Childcare' (SNAC) study, via online conversation threads, observations and qualitative interviews. Findings demonstrated that whilst many Early Childhood Education and Care services are committed to supporting food sharing and family-style mealtime practices, a number of barriers were reported. These included the perception that babies and toddlers could not participate in these practices, concerns about food hygiene and cross contamination of allergens, and negative parental influences on food sharing. In conclusion, this paper supports the practice of food sharing in Early Childhood Education and Care settings and calls for them to become embedded in everyday operations to support the physical, social and emotional development of Australia's future generations.

Meal planning by high and low health conscious individuals during a simulated shop in the supermarket: A mixed methods study.

Planning is an essential component of home meal preparation. While level of health consciousness permeates both activities, this relationship is underexplored in the scientific literature. Using a mixed-methods convergent parallel design this study identified the reasoning behind meal planning and compared the characteristics of meals planned by high and low health-conscious adults during a simulated shopping task in a supermarket store. Participants were assigned a task where they were asked to choose ingredients to prepare a hot evening meal for a last-minute guest. High Health Conscious (HHC) participants planned healthier meals with more whole grains/breads/pasta, fruits, and vegetables than Low Health Conscious (LHC) participants. HHC participants mentioned not only health-related motives, but also ingredients' characteristics and cooking habits as influencers of their choices. LHC individuals focused on their own preferences, acknowledged that they struggled with the skills needed to prepare a meal and considered the presence of a guest as the only reason why they would prepare a meal. The mixed methods approach enabled us to link the participants' reasoning with the quantitative differences between meals planned by them - HHC individuals planned healthier meals and manifested closeness to the act of cooking. This suggests that the link between health interest and learning how to cook deserves to be further explored.

Meal planning values impacted by the cancer experience in families with school-aged survivors-a qualitative exploration and recommendations for intervention development.

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.

Time spent looking at food during a delay of gratification task is positively associated with children's consumption at ad libitum laboratory meals.

Greater ability to delay gratification for an immediate food reward may protect against the development of obesity. However, it is not known if the behaviors children exhibit during a delay of gratification task are related to overeating in other contexts. The purpose of this analysis was to assess the relationship between observed child coping strategies during a delay of gratification task and laboratory intake from ad libitum test-meals. The sample consisted of 40, 7-9 year old children (40% (N = 16 with overweight/obesity). Across 5 laboratory visits, children consumed 3 identical test-meals presented after varying exposure conditions (i.e., no exposure, exposure to food commercials, exposure to toy commercials). On the first visit, children were recorded during a delay of gratification task which was coded for three behavioral themes: looking at vs. away from food, talking vs. staying silent, and fidgeting vs. sitting still. Pearson correlations and multiple regressions were run to look at the relationships between coping strategies and test-meal intake. Time spent looking away from food was negatively associated with ad libitum food consumption at the meals. Conversely, greater time spent looking at food was positively associated with ad libitum food consumption. These relationships were independent of covariates likely to influence intake (e.g., sex, age, weight status, parent income) and were more robust following food rather than toy commercial exposure. Children who spent more time looking at food and less time looking away during a delay of gratification task may be vulnerable to overeating in other contexts. Upon replication in larger samples, these behaviors could serve as modifiable targets in the development of childhood obesity prevention programs.

Everyday life situations in which mothers experience difficulty stimulating healthy energy balance-related behavior in their school-age children: a focus group study.

BACKGROUND: Parental support is an important element in overweight prevention programs for children. The purpose of this study was to examine everyday life situations in which mothers encounter difficulties encouraging healthy energy balance-related behavior in their school-age children. METHODS: We formed four focus groups containing 6-9 participants each. The participants were mothers of Dutch, Turkish, or Moroccan descent with a child 8-13 years of age. All focus group sessions were recorded, transcribed, and coded. Content was analyzed conventionally using ATLAS.ti 6. RESULTS: Twenty-seven difficult everyday life situations were identified in 14 settings. The five most frequently reported situations were a daily struggle regarding eating vegetables, eating breakfast on time before going to school, eating candy and snacks between meals, and spending excessive time watching television and using the computer. A perceived loss of parental control, the inability to establish rules and the failure to consistently enforce those rules were the most commonly cited reasons for why the mothers experience these situations as being difficult. CONCLUSIONS: We identified five difficult everyday life situations related to healthy energy balance-related behavior. These five difficult situations were used as the input for developing a web-based parenting program designed to prevent children from becoming overweight. We reasoned that if we use these situations and the underlying reasons, many parents would recognize these situations and are willing to learn how to deal with them and complete the e-learning.

Applying the disgust conditioning model of food avoidance: A case study of acceptance-based interoceptive exposure.

OBJECTIVE: The current case report details the treatment of a 16-year-old adolescent with anorexia nervosa utilizing a novel adjunct, acceptance-based interoceptive exposure, prior to family-based treatment (FBT) for eating disorders. METHOD: The exposure-based module focused particularly on the tolerance of disgust. For six sessions, the clinician taught the client skills that could be used to tolerate distress to visceral sensations associated with disgust. These skills were to be used during in- and between-session exposures. Each session included exposure to physical sensations that occurred while drinking a milkshake. RESULTS: Across six sessions, the client reported improvement in symptoms in addition to gaining weight. Additionally, she consumed more calories of a test meal following the intervention. Within broader FBT, the client reached an established weight goal, was able to return to physical activity, and reported an increased ability to manage distress. DISCUSSION: Given the client's improvement on the Eating Disorders Examination-Questionnaire (EDE-Q) within six sessions, we believe IE may be a useful adjunct to FBT. Interoceptive exposure may augment the efficacy of FBT for anorexia nervosa as it provides clients with skills to utilize during the refeeding phase of treatment.

Impact of Head and Neck Cancer Treatment on Survivors' Mealtime Experience.

OBJECTIVES/HYPOTHESIS: The objectives of the study were to develop a mealtime experience self-assessment questionnaire that was head and neck cancer (HNC) survivors-driven and based on the International Classification of Functioning, Disability and Health (ICF) framework, and to identify common mealtime issues reported by HNC survivors. STUDY DESIGN: Outcomes research. METHODS: Mealtime issues reported by HNC survivors in prior research was synthesized and classified using the ICF framework to develop the content and structure of the Head and Neck Cancer Survivors' Assessment of Mealtimes (HNSAM). A total of 122 HNC survivors completed both HNSAM and M.D. Anderson Dysphagia Inventory (MDADI) to assess for concurrent validity, whereas 51% of participants completed a second HNSAM for test-retest reliability. RESULTS: The HNSAM scores were significantly correlated with the MDADI scores. Dysphagic participants (n = 45) had significantly higher HNSAM scores than the nondysphagic participants (n = 77). Principal component analysis revealed three factors that matched with the HNSAM subscales. Good internal consistency (Cronbach's α = 0.72-0.96) and test-retest reliability (intraclass correlation = 0.76-0.91) were found. Both dysphagic and nondysphagic participants reported difficulties with saliva-related issues and were not able to enjoy food/drinks that they previously enjoyed. CONCLUSIONS: HNC survivors experience mealtime changes after cancer treatment. These initial validity data support the potential for the HNSAM to help HNC survivors' identify changes to the mealtime experience. Validation of the English version of the tool is now required. LEVEL OF EVIDENCE: 2c Laryngoscope, 129:1572-1578, 2019.

Perception of Hunger/Satiety and Nutrient Intake in Women Who Regain Weight in the Postoperative Period After Bariatric Surgery.

OBJECTIVE: To investigate the perception of hunger and satiety and its association with nutrient intake in women who regain weight in the postoperative period after bariatric surgery. METHODS: Cross-sectional study of adult women divided into three groups: weight regain (n = 20), stable weight (n = 20) (both at least 24 months after Roux-en-Y gastric bypass surgery), and non-operated obesity (n = 20). A visual analogue scale measured hunger/satiety perception while fasting, immediately after finishing a test meal, and 180 min after finishing the test meal. The incremental area above or under the curve was calculated. Food intake was analyzed by 3 days of food recall and adjusted for intraindividual variation. To make between-group comparisons, Mann-Whitney, ANOVA, Kruskal-Wallis, and independent-samples T tests and Pearson's correlation were used. RESULTS: There were no between-group differences in incremental areas of hunger/satiety, but protein intake was significantly lower among patients who regained weight compared with those who had stable body weight (0.99 ± 0.23 g/kg body weight vs. 1.17 ± 0.21 g/kg body weight, p = 0.047). In the group that regained weight, satiety was correlated positively with usual dietary protein density (r = 0.541; p = 0.017) and negatively with usual carbohydrate intake (r = - 0.663; p = 0.002). CONCLUSION: Women who regained weight presented similar perceptions of hunger/satiety to those of patients without weight regain and with non-operated obesity. In patients who regained weight postoperatively, satiety perception was correlated positively with usual dietary protein density and inversely with usual carbohydrate intake.

Fazer refeições com os pais está associado à maior qualidade da alimentação de adolescentes brasileiros / Comer con los padres está asociado a una mayor calidad en la alimentación de los adolescentes brasileños / Eating meals with parents is associated with better quality of diet for Brazilian adolescents

Resumo: O objetivo foi investigar a frequência com que os adolescentes brasileiros realizam as refeições com os pais e verificar a associação deste hábito com a qualidade da dieta. Foram utilizados dados da Pesquisa Nacional de Saúde do Escolar - 2015 (PeNSE). A amostra foi composta por adolescentes matriculados no nono ano do ensino fundamental de escolas públicas e privadas, com idades entre 11 e 19 anos. A exposição de interesse foi realizar refeições com os pais (0-4 e ≥ 5 dias/semana) e os desfechos estudados foram consumo frequente (≥ 5 dias/semana) de alimentos marcadores de alimentação saudável e não saudável. Escores de alimentação saudável (variação 0-21) e não saudável (variação 0-35) foram elaborados com base no somatório dos dias que o adolescente relatou consumir cada um dos marcadores de alimentação. Foram usados modelos de regressão de Poisson e linear, ajustados por variáveis sociodemográficas. A realização frequente de refeições com os pais (≥ 5 dias/semana) foi observada em 74% (IC95%: 73,4-74,7) dos adolescentes. Aqueles que afirmaram ter esse hábito apresentaram maior probabilidade do consumo frequente de feijão (RP = 1,22; IC95%: 1,19-1,26), frutas (RP = 1,34; IC95%: 1,28-1,39) e hortaliças (RP = 1,39; IC95%: 1,34-1,44); e menor probabilidade de consumo frequente de guloseimas (RP = 0,91; IC95%: 0,88-0,94), ultraprocessados salgados (RP = 0,91; IC95%: 0,87-0,94) e salgados fritos (RP = 0,85; IC95%: 0,80-0,90). Realizar as refeições com os pais foi positivamente associado ao escores de alimentação saudável e inversamente associado ao escores de alimentação não saudável. O hábito de realizar refeições com os pais é frequente entre adolescentes brasileiros e está associado à melhor qualidade da alimentação.

Resumen: El objetivo fue investigar la frecuencia con la que los adolescentes brasileños comen con los padres y verificar la asociación de este hábito con la calidad de la dieta. Se utilizaron datos de la Encuesta Nacional de Salud del Escolar - 2015 (PeNSE). La muestra estaba compuesta por adolescentes matriculados en el noveno año de enseñanza fundamental de escuelas públicas y privadas, con edades entre 11 y 19 años. La exposición de interés fue realizar comidas con los padres (0-4 y ≥ 5 días/semana) y los resultados estudiados fueron consumo frecuente (≥ 5 días/semana) de alimentos marcadores de alimentación saludable y no saludable. Los marcadores de alimentación saludable (variación 0-21) y no saludable (variación 0-35) se elaboraron basándose en el sumatorio de los días en los que el adolescente informó consumir cada uno de los marcadores de alimentación. Se usaron modelos de regresión de Poisson y lineales, ajustados por variables sociodemográficas. La realización frecuente de comidas con los padres (≥ 5 días/semana) se observó en un 74% (IC95%: 73,4-74,7) de los adolescentes. Aquellos que afirmaron tener ese hábito presentaron una mayor probabilidad de consumo frecuente de frijoles (RP = 1,22; IC95%: 1,19-1,26), frutas (RP = 1,34; IC95%: 1,28-1,39) y hortalizas (RP = 1,39; IC95%: 1,34-1,44); y menor probabilidad de consumo frecuente de golosinas (RP = 0,91; IC95%: 0,88-0,94), aperitivos ultraprocesados (RP = 0,91; IC95%: 0,87-0,94) y aperitivos fritos (RP = 0,85; IC95%: 0,80-0,90). Realizar las comidas con los padres estuvo positivamente asociado al marcadores de alimentación saludable e inversamente asociado al marcadores de alimentación no saludable. El hábito de realizar comidas con los padres es frecuente entre adolescentes brasileños y está asociado a una mejor calidad de la alimentación.

Abstract: The objective was to investigate how often Brazilian adolescents eat meals with their parents and verify the association between this habit and quality of the diet. Data were from the Brazilian National Survey of School Health (PeNSE-2015). The sample consisted of adolescents enrolled in the ninth grade in public and private schools, ranging in age from 11 to 19 years. The target exposure was eating meals with parents (0-4 and ≥ 5 days/week) and the outcomes were frequent consumption (≥ 5 days/week) of healthy and unhealthy dietary markers. Healthy diet scores (range 0-21) and unhealthy diet scores (range 0-35) were based on total days that the adolescent reported consuming each of the dietary markers. Poisson and linear regression models were used, adjusted by sociodemographic variables. Frequent sharing of meals with parents (≥ 5 days/week) was seen in 74% (95%CI: 73.4-74.7) of the adolescents. Those reporting this habit showed higher likelihood of frequent consumption of beans (PR = 1.22; 95%CI: 1.19-1.26), fruits (PR = 1.34; 95%CI: 1.28-1.39), and vegetables (PR = 1.39; 95%CI: 1.34-1.44), and lower likelihood of frequent consumption of sweets (PR = 0.91; 95%CI: 0.88-0.94), ultra-processed salty foods (PR = 0.91; 95%CI: 0.87-0.94), and fried salty snacks (PR = 0.85; 95%CI: 0.80-0.90). Eating meals with parents was positively associated with healthy diet scores and inversely associated with unhealthy diet scores . Eating meals with parents is a common habit in Brazilian adolescents and is associated with better quality of diet.

Frequência de refeições e associação com estado nutricional e marcadores cardiometabólicos em adolescentes de escolas públicas de João Pessoa, Paraíba / Meals frequency and association with nutritional status and cardiometabolic markers in adolescents of public schools in João Pessoa, Paraíba

Introdução: O aumento da prevalência de obesidade entre populações cada vez mais jovens tem sido observado em várias partes do mundo e representa uma condição associada à presença de fatores de risco centrais para o desenvolvimento de doenças cardiovasculares. Estudos epidemiológicos em adolescentes têm demonstrado uma relação inversa entre a frequência de refeições e o peso corporal e adiposidade abdominal. Recentemente, esse efeito também tem sido observado em relação às concentrações de lipídios séricos, porém os dados ainda são inconsistentes. Objetivo: analisar a associação da frequência de refeições com o estado nutricional e marcadores cardiometabólicos de adolescentes de escolas públicas do município de João Pessoa, Paraíba. Metodologia: Trata-se de um estudo transversal, desenvolvido a partir dos dados da linha de base do Estudo LONCAAFS, com amostra representativa de adolescentes de ambos os sexos, estudantes do sexto ano de escolas públicas do município de João Pessoa, PB, totalizando 1.438 indivíduos. O consumo alimentar foi avaliado por meio do Recordatório de 24h. Medidas antropométricas (peso, altura, circunferência da cintura) foram realizadas para classificação do estado nutricional através do IMC, da razão cintura/estatura e do índice de conicidade. Para avaliar o perfil lipídico, foi realizada coleta de sangue em uma subamostra (n=808) e dosado a concentração sérica de colesterol total, lipoproteína de alta densidade, lipoproteína de baixa densidade e triglicerídeos plasmáticos. Os adolescentes foram estratificados em dois grupos, de acordo com a mediana de consumo energético (2040,5kcal). Para avaliar a associação da frequência de refeições com o estado nutricional e perfil lipídico, foram utilizados modelos de regressão logística. O nível de significância foi estabelecido em p <0,05. Resultados: A porcentagem de excesso de peso na população de estudo foi de 32%. Dentre os adolescentes que realizaram a coleta de sangue, cerca de 77% apresentaram dislipidemia. Na análise estratificada, o maior número de refeições associou-se inversamente com a obesidade abdominal no grupo com consumo energético abaixo da mediana. Nos indivíduos com consumo energético acima da mediana, houve tendência à quanto maior o número de refeições, menor a chance de HDL-c baixo (p=0,03). Não houve associação significativa entre número de refeições e as demais variáveis de risco cardiometabólico. Conclusão: A frequência de refeições mostrou-se significativamente associada à obesidade abdominal em indivíduos com consumo energético abaixo da mediana de ingestão da população e ao HDL-c nos indivíduos com consumo energético acima da mediana.

Introduction: The increasing prevalence of obesity among younger and younger populations has been observed in several parts of the world and is a condition associated with the presence of central risk factors for the development of cardiovascular diseases. Epidemiological studies in adolescents have shown an inverse relationship between meal frequency and body weight and abdominal adiposity. Recently, this effect has also been observed in relation to serum lipid concentrations, but the data are still inconsistent. Objective: to analyze the association of meal frequency with nutritional status and cardiometabolic markers of adolescents from public schools in the city of João Pessoa, Paraíba. Methodology: This is a cross-sectional study, based on data from the LONCAAFS study, with a representative sample of adolescents of both sexes, sixth-year students from public schools in the city of João Pessoa, PB, totaling 1,438 individuals. Food consumption was assessed through the 24-hour Reminder. Anthropometric measurements (weight, height, waist circumference) were performed to classify the nutritional status through BMI, waist / height ratio and conicity index. To evaluate the lipid profile, blood was collected in a subsample (n = 808) and serum levels of total cholesterol, high density lipoprotein, low density lipoprotein and plasma triglycerides were measured. Adolescents were stratified into two groups, according to the median energy consumption (2040.5kcal). To evaluate the association of meal frequency with nutritional status and lipid profile, logistic regression models were used. The level of significance was set at p <0.05. Results: The percentage of overweight in the study population was 32%. Among adolescents who performed blood collection, approximately 77% had dyslipidemia. In the stratified analysis, the highest number of meals was inversely associated with abdominal obesity in the group with energy consumption below the median. In individuals with energy consumption above the median, there was a tendency to the higher the number of meals, the lower the chance of low HDL-c (p = 0.03). There was no significant association between number of meals and the other variables of cardiometabolic risk. Conclusion: Meal frequency was significantly associated with abdominal obesity in subjects with energy consumption below the median ingestion of the population and with HDL-c in subjects with energy consumption above the median.

Is brain response to food rewards related to overeating? A test of the reward surfeit model of overeating in children.

The reward surfeit model of overeating suggests that heightened brain response to rewards contributes to overeating and subsequent weight gain. However, previous studies have not tested whether brain response to reward is associated with food intake, particularly during childhood, a period of dynamic development in reward and inhibitory control neurocircuitry. We conducted functional magnetic resonance imaging (fMRI) with 7-11-year-old children (n = 59; healthy weight, n = 31; overweight, n = 28; 54% female) while they played a modified card-guessing paradigm to examine blood-oxygen-level-dependent (BOLD) response to anticipating and winning rewards (food, money, neutral). Food intake was assessed at three separate meals that measured different facets of eating behavior: 1) typical consumption (baseline), 2) overindulgence (palatable buffet), and 3) eating in the absence of hunger (EAH). A priori regions of interest included regions implicated in both reward processing and inhibitory control. Multiple stepwise regressions were conducted to examine the relationship between intake and BOLD response to rewards. Corrected results showed that a greater BOLD response in the medial prefrontal cortex for anticipating food compared to money positively correlated with how much children ate at the baseline and palatable buffet meals. BOLD response in the dorsolateral prefrontal cortex for winning food compared to money was positively correlated with intake at the palatable buffet meal and EAH. All aforementioned relationships were independent of child weight status. Findings support the reward surfeit model by showing that increased brain response to food compared to money rewards positively correlates with laboratory measures of food intake in children.
