RESUMEN

BACKGROUND: The exploitative marketing of commercial milk formula (CMF) reduces breastfeeding, and harms child and maternal health globally. Yet forty years after the International Code of Marketing of Breast-Milk Substitutes (The Code) was adopted by WHO member states, many countries are still to fully implement its provisions into national law. Furthermore, despite The Code, worldwide CMF markets have markedly expanded. In this paper, we adopt Brazil as a case study to understand the power of the baby food industry's marketing and corporate political activity, and how this influences the country's 'first-food system' in ways that promote and sustain CMF consumption. METHODS: We used a case study design, drawing data from from documents and key informant interviews (N = 10). RESULTS: Breastfeeding rates plummeted in Brazil to a historic low in the 1970s. A resurgence in breastfeeding from the mid-1980s onwards reflected strengthening political commitment for a national policy framework and breastfeeding protection law, resulting in-turn, from collective actions by breastfeeding coalitions, advocates, and mothers. Yet more recently, improvements in breastfeeding have plateaued in Brazil, while the industry grew CMF sales in Brazil by 750% between 2006 and 20. As regulations tightened, the industry has more aggressively promoted CMF for older infants and young children, as well as specialised formulas. The baby food industry is empowered through association with powerful industry groups, and employs lobbyists with good access to policymakers. The industry has captured the pediatric profession in Brazil through its long-standing association with the Brazilian Society of Pediatrics. CONCLUSION: Brazil illustrates how the baby food industry uses marketing and political activity to promote and sustain CMF markets, to the detriment of breastfeeding. Our results demonstrate that this industry requires much greater scrutiny by regulators.

RESUMEN

OBJECTIVE: This paper describes the first web-based self-completed 24-h recall designed to categorise food intake according to Nova groups - Nova24h - and its agreement with a reference tool in estimating the dietary relative contribution of the four Nova food groups (% of total energy intake). DESIGN: Comparisons of estimates of dietary relative contributions of Nova groups obtained by Nova24h and one standard interviewer-led 24-h recall. SETTING: Nationwide adult cohort study in Brazil. PARTICIPANTS: The subjects were 186 participants of the NutriNet Brasil Cohort Study (n 186). RESULTS: No statistically significant differences were observed between the Nova24h and the reference tool mean contributions of unprocessed or minimally processed foods (52·3 % v. 52·6 %), processed culinary ingredients (11·6 % v. 11·9 %), processed foods (17·1 % v. 14·7 %) and ultra-processed foods (19·0 % v. 20·9 %). Intraclass correlation coefficients between individual estimates obtained for each Nova group showed moderate to good agreement (0·54-0·78). Substantial or almost perfect agreement between the tools was seen regarding the ability to rank participants according to quintiles of contribution of each Nova group (PABAK 0·69-0·81). CONCLUSIONS: Nova24h is a suitable tool for estimating the dietary relative energy contribution of Nova food groups in the NutriNet Brasil cohort. New studies are necessary to verify its adequacy in other populations.

RESUMEN

The current study aims to describe the consumption of ultra-processed foods, from 2 to 4 years old, and evaluate its association with growth outcomes during the same period. It is a prospective cohort study using data from the 2015 Pelotas-Brazil Birth Cohort. Outcomes assessed at the 2- and 4-year-old follow-ups were BMI-for-age Z-score and length/height-for-age Z-score. The exposure was a score of ultra-processed food consumption calculated at each follow-up by summing up the positive answers for the consumption of nine specific items/subgroups of ultra-processed foods: (i) instant noodles; (ii) soft drink; (iii) chocolate powder in milk; (iv) nuggets, hamburger or sausages; (v) packaged salty snacks; (vi) candies, lollipops, chewing gum, chocolate or jelly; (vii) sandwich cookie or sweet biscuit; (viii) juice in can or box or prepared from a powdered mix and (ix) yogurt. Crude and adjusted analyses between the score of ultra-processed foods and the outcomes were run using generalised estimating equations. Prevalence of consumption of ultra-processed foods increased from 2 to 4 years old, for all evaluated items/subgroups, except yogurt. In prospective analyses, higher scores of ultra-processed food consumption were associated with higher BMI-for-age Z-score and lower length/height-for-age Z-score, after adjustment for confounders. Ultra-processed food consumption, measured using a short questionnaire with low research burden, increased from 2 to 4 years old and was related to deleterious growth outcomes in early childhood. These results reinforce the importance of avoiding the consumption of these products in childhood to prevent the double burden of malnutrition and non-communicable chronic diseases throughout the life.

RESUMEN

This study sought to examine the relationship between dietary share of ultra-processed foods and metabolic syndrome among US adults. We studied 6, 385 participants from the cross-sectional National Health and Nutrition Examination Survey 2009-2014, aged 20+ years, with blood tests under fasting conditions and at least one 24-hour dietary recall. Food items were classified according to the extent and purpose of industrial food processing. Ultra-processed foods (UPF) are formulations of many ingredients, mostly of exclusive industrial use, that result from a sequence of industrial processes (hence ultra-processed). Metabolic Syndrome (MetS) was defined according to the 2009 Joint Scientific Statement as meeting three or more of the following criteria: (1) elevated waist circumference (2) elevated fasting plasma glucose (3) elevated blood pressure (4) elevated triglycerides (5) reduced high-density lipoprotein (HDL-C). Poisson regression models with robust variance adjusted for age, sex, race/ethnicity, family income, education, physical activity and smoking showed significant linear association between the dietary contribution of UPF and the prevalence of MetS (a 10% increase in contribution was associated with a 4% prevalence increase) (prevalence ratio -PR- = 1.04; 95% CI 1.02, 1.07). A dietary UPF contribution of >71% (5th population quintile) was associated with 28% higher prevalence of MetS compared to a contribution below 40% (1st population quintile) (PR = 1.28; 95% CI 1.09, 1.50). The association was stronger in young adults (PR between upper and lower quintiles = 1.94; 95% CI 1.39, 2.72) and decreased with age. These findings add to the growing evidence that UPF consumption is associated with diet-related non-communicable diseases.

RESUMEN

The present commentary contains a clear and simple guide designed to identify ultra-processed foods. It responds to the growing interest in ultra-processed foods among policy makers, academic researchers, health professionals, journalists and consumers concerned to devise policies, investigate dietary patterns, advise people, prepare media coverage, and when buying food and checking labels in shops or at home. Ultra-processed foods are defined within the NOVA classification system, which groups foods according to the extent and purpose of industrial processing. Processes enabling the manufacture of ultra-processed foods include the fractioning of whole foods into substances, chemical modifications of these substances, assembly of unmodified and modified food substances, frequent use of cosmetic additives and sophisticated packaging. Processes and ingredients used to manufacture ultra-processed foods are designed to create highly profitable (low-cost ingredients, long shelf-life, emphatic branding), convenient (ready-to-consume), hyper-palatable products liable to displace all other NOVA food groups, notably unprocessed or minimally processed foods. A practical way to identify an ultra-processed product is to check to see if its list of ingredients contains at least one item characteristic of the NOVA ultra-processed food group, which is to say, either food substances never or rarely used in kitchens (such as high-fructose corn syrup, hydrogenated or interesterified oils, and hydrolysed proteins), or classes of additives designed to make the final product palatable or more appealing (such as flavours, flavour enhancers, colours, emulsifiers, emulsifying salts, sweeteners, thickeners, and anti-foaming, bulking, carbonating, foaming, gelling and glazing agents).

RESUMEN

OBJECTIVES: Gender continues to be largely neglected in the global response to the noncommunicable disease epidemic. The objectives of this study were to examine current practice and barriers faced by Latin American and Caribbean (LAC) researchers in addressing gender in research on healthy food environments, and to identify future topics for gender-sensitive and gender-transformative research. METHODS: This study involved: 1) a descriptive, three-part survey to investigate to what extent LAC researchers are integrating gender considerations in research for healthier food environments and 2) a participatory workshop to coproduce ideas for future gender-sensitive and gender-transformative research. RESULTS: Fifty-four participants, from 19 countries, attended the workshop. Of those 54, 41 of them responded to at least one section of the three-part survey, including with 26 of the 41 responding to the section on gender. Of these 26, 17 (65.4%) had collected sex-disaggregated data and 14 (53.8%) had conducted gender analysis in recent research on food environments. Few participants had integrated gender-related findings in their recommendations and solutions. Challenges included data and methodological limitations (e.g., lack of preexisting evidence, working with secondary data), knowledge and capacity gaps, subject sensitivity, and biases. Participants identified research topics for enhancing gender equity that included food preparation norms and domestic responsibilities; differential participation of women and men in food production, distribution, and retail; and employment and school policies. CONCLUSIONS: The findings from this study suggest that gender inequity is not being well addressed in food environment research from the LAC region. The analytical framework presented here can serve as an important starting point and resource for catalyzing future gender-transformative research. Complementary efforts are needed to overcome other challenges raised by the participating researchers, including capacity gaps, resource and data limitations, and publishing barriers.

RESUMEN

This study aimed to assess the association between watching TV whilst eating and consumption of ultraprocessed foods amongst children aged 4-10 years old in the United Kingdom. Cross-sectional data from the UK National Diet and Nutrition Survey (NDNS 2008-2012) were analysed. Dietary data were derived from 4-day food diaries of 1,277 children, and the dietary contribution of ultraprocessed foods was assessed. Meals were classified based on time of day in which foods were consumed (lunch: 11 pm-3 pm and dinner: 6 pm-9 pm). Crude and adjusted linear regression models were employed to verify the effect of watching TV during meals on dietary contribution of ultraprocessed foods (% of total energy intake). More than 70% of the children watched TV during meals, and 31.4% presented the behaviour on both "lunch and dinner." Children's mean total energy intake was 1,532.3 kcal/day, of which 65.8% came from ultraprocessed foods. Findings indicated that children who watched TV whilst having both meals (lunch and dinner) consumed on average 85.5 kcal/day and 6.1% more energy from ultraprocessed foods than those who did not. Children who watched TV only during dinner consumed on average 37.1 kcal/day and 3.4% more energy from ultraprocessed foods than those who did not. The behaviour of watching TV whilst eating meals was associated with higher total daily consumption of ultraprocessed foods by children in the United Kingdom. Therefore, interventions designed to promote healthy eating habits should include aspects related to the context of meals.

RESUMEN

INTRODUCTION: HIV-exposed, uninfected (HEU) infants are potentially at risk for cardiovascular disease due to in utero exposures. Feeding practices of the infant could compound this risk. Few studies have, however, evaluated dietary intake of HEU infants. We determined dietary factors associated with rapid weight gain (RWG) among HEU infants from birth to 6 months followed at the University of Miami HIV Screening Program. METHODS: In this cross-sectional analysis, logistic regression was used to determine dietary factors associated with RWG defined as a >0.67 SD change in weight-for-age z score from birth to assessment (0.3-6 months). Other covariates included demographics, birth, maternal and gestational characteristics, and antiretroviral exposures. RESULTS: A total of 86 full-term HEU infants with a mean age of 3.4 months (SD 1.8 months) were included in this analysis. Fifty-five percent of mothers were obese. Overall, 39.5% of infants exhibited RWG. A significant association between consumption of infant cereal and RWG (odds ratio, 3.52; 95% confidence interval, 1.02-12.10) was found after adjusting for birth weight, current age, and energy intake. Those infants who consumed the highest tertile of protein were less likely to gain weight rapidly after adjusting for the same covariates (odds ratio, 0.15; 95% confidence interval, 0.02-0.94). CONCLUSIONS: Overall differences in weight gain during early infancy are at least partly explained by means of infant feeding in young HEU infants in the United States. Dietary counseling for families of HEU should reinforce current feeding practice recommendations of the American Academy of Pediatrics.

RESUMEN

We determined factors associated with diet quality and assessed the relationship between diet quality, birth weight, and gestational age in a prospective national multicenter cohort study. We evaluated diet quality with the Healthy Eating Index (HEI, scale 0-100) in the third trimester of pregnancy with three 24-hr multiple-pass dietary recalls in 266 HIV+ women enrolled in the Pediatric HIV/AIDS Cohort Study. Covariates included demographics, food security, pre-pregnancy body mass index, HIV disease severity, substance use, and antiretroviral exposures. A two-stage multivariate process using classification and regression trees (CART) followed by multiple regression described HEI tendencies, controlled possible confounding effects, and examined the association of HEI with birth weight and gestational age. To assess the stability of the CART solution, both the HEI 2005 and 2010 were evaluated. The mean HEI scores were 56.1 and 47.5 for the 2005 and 2010 HEI, respectively. The first-stage CART analysis examined the relationship between HEI and covariates. Non-US born versus US-born mothers had higher HEI scores (15-point difference, R2  = 0.28). There was a secondary partition due to alcohol/cigarette/illicit drug usage (3.5-point difference, R2  = 0.03) among US-born women. For the second-stage CART adjusted multiple regression, birth weight z-score was positively related to HEI 2005 and 2010 (partial r's > 0.13, P's ≤ 0.0398), but not gestational age (r = 0.00). We conclude that diet quality among HIV+ women is associated with higher birth weight. Despite the influence of a large cultural effect and poor prenatal behaviors, interventions to improve diet in HIV+ women may help to increase birth weight.

RESUMEN

OBJECTIVES: Human immunodeficiency virus (HIV)-infected youth are healthier because of effective antiretroviral therapies. We compared anthropometric measurements and prevalence of overweight and obesity between perinatally HIV-infected youth, a local HIV-uninfected comparison group, and 2007 to 2010 National Health and Nutrition Examination Survey (NHANES) data. In addition, we compared only African American HIV-infected youth with NHANES African Americans. METHODS: Height, weight, body mass index (BMI), and waist circumference (WC) of HIV-infected youth, aged 10 to 19 years, were compared among groups. BMI percentiles were categorized as underweight (<5%), normal (5% to <85%), overweight (85% to <95%), and obese (≥ 95%). Clinical correlates were modeled as predictors of BMI and WC. RESULTS: A total of 134 HIV-infected (including 103 African Americans) (mean age 16.5 years), 75 HIV-uninfected (mean age 14.2 years), and 3216 NHANES (including 771 NHANES African Americans) (mean age 15.0 years) youth were included in the analysis. Height and weight z scores of HIV-infected youth were lower than those of HIV-uninfected and NHANES (P ≤ 0.056) youth. BMI, WC, and BMI category were not statistically different between groups. In the HIV-infected African American group, BMI z score was lower (0.49 vs 0.76, P = 0.04) compared with NHANES African Americans. There were no significant predictors of BMI or WC for the HIV-infected group. CONCLUSIONS: HIV-infected children have similar BMIs and WCs as uninfected children both locally and nationally and show similar high rates of obesity and overweight. When compared with a more racially similar African American national sample, HIV-infected children have a lower BMI, suggesting that there may be persistent anthropometric differences in HIV.

RESUMEN

BACKGROUND: Global trends toward childhood obesity have been associated with several factors, including suboptimal infant feeding practices, the increasing availability of ultraprocessed foods in the world's food supply, and the corresponding changes in children's dietary patterns. OBJECTIVE: To describe infants' dietary patterns and assess their associations with weight status outcomes in a nationally representative sample of US infants. DESIGN: Cross-sectional analyses were performed on data collected from infants participating in the 2009-2018 National Health and Nutrition Examination Survey. PARTICIPANTS/SETTING: Participants included 744 infants aged 6 to 12 months who had data from at least 1 day of valid 24-hour dietary recall data. MAIN OUTCOME MEASURES: Rapid weight gain and overweight/obesity risk. STATISTICAL ANALYSES PERFORMED: Principal component analysis was used to identify dietary patterns considering the energy intake of 39 Nova food subgroups (expressed in calories per day), including breast milk. Associations were evaluated using logistic regression adjusted for potential confounders. RESULTS: A total of 42% infants experienced rapid weight gain, and 33% were at risk of overweight/obesity. Most infants (65.5%) were started on solid foods early. Three main dietary patterns were derived. The first pattern, labeled Natural or Minimally Processed Foods, had positive loadings for a variety of natural or minimally processed foods, some processed culinary ingredients, and a few processed and ultraprocessed foods. The second pattern, labeled Infant Formula, had high negative loading for breast milk, and high positive loading for infant formula and breakfast cereal. The third pattern, labeled Ultraprocessed Foods, had negative loadings for natural or minimally processed foods and processed culinary ingredients, positive loadings for other processed foods and for a variety of ultraprocessed foods, and negative loading for infant formula. Infants who adhere to the Ultraprocessed Foods dietary pattern were more likely to present rapid weight gain (adjusted odds ratio 1.3, 95% CI 1.1 to 1.5) and overweight/obesity risk (adjusted odds ratio 1.2, 95% CI 1.0 to 1.4). CONCLUSIONS: Higher adherence to a dietary pattern characterized by ultraprocessed foods was associated with a greater likelihood of both rapid weight gain and overweight/obesity risk early in life. Promoting breastfeeding and increasing consumption of unprocessed/minimally processed foods during early infancy while restricting ultraprocessed foods are key components to reducing the growing burden of childhood obesity.

RESUMEN

OBJECTIVE: To compare growth and body composition of uninfected children exposed to HIV with a contemporary HIV-unexposed group and to US references. STUDY DESIGN: Uninfected children exposed to HIV under 2 years were enrolled into a longitudinal observational study and unexposed children under 2 years of age in a cross-sectional evaluation. Weights, lengths, head circumferences, skinfold thicknesses, and arm and thigh circumferences were measured and adjusted for age using Centers for Disease Control and National Health and Nutrition Examination Survey standards. Uninfected children exposed to HIV were compared with an unexposed nearest-neighbor matched comparison group. Uninfected children exposed to HIV were compared by age to Centers for Disease Control standards for growth measures and National Health and Nutrition Examination Survey standards for body composition. RESULTS: One hundred eleven uninfected children exposed to HIV and 82 children not exposed to HIV were evaluated. For the matched comparison for both groups, the mean age was 10 months, 59% were male, and 73% were African American. No statistical differences were found in anthropometric measurements between uninfected children who were or were not exposed to HIV. Uninfected children exposed to HIV were smaller than US standards at birth with mean (SD) weight-for-age and weight-for-length z-scores of -0.39 (1.06); P = .002 and -0.35 (1.04); P = .005, respectively. Over the first 2 years of life, there was a trend toward increasing weight-for-age z-score, length-for-age z-score, and weight-for-length z-score in uninfected children exposed to HIV. Subscapular and triceps skinfolds among uninfected children exposed to HIV were lower than national standards and there was a trend that mid-upper arm circumference decreased over time. CONCLUSIONS: Growth and body composition of uninfected children who were or were not exposed to HIV were similar. Uninfected children exposed to HIV weigh less at birth and show a pattern of slightly accelerated growth in the first 2 years of life. Uninfected children exposed to HIV had less subcutaneous fat and decreasing mid-upper arm circumference over time when compared with US standards.

RESUMEN

Food insecurity, micronutrient deficits, dyslipidemia, insulin resistance, obesity, cardiovascular disease, and bone disorders complicate the treatment of HIV infection. Nutrition and exercise interventions can be effective in ameliorating these symptoms that are associated with HIV and antiretroviral therapy (ART). In this literature review, we examine the most recent nutrition and exercise interventions for HIV-infected patients. Macronutrient supplementation can be useful in treating malnutrition and wasting. Multivitamin (vitamin B complex, vitamin C, and vitamin E) supplements and vitamin D may improve quality of life and decrease morbidity and mortality. Nutritional counseling and exercise interventions are effective for treating obesity, fat redistribution, and metabolic abnormalities. Physical activity interventions improve body composition, strength, and fitness in HIV-infected individuals. Taken collectively, the evidence suggests that a proactive approach to nutrition and physical activity guidance and interventions can improve outcomes and help abrogate the adverse metabolic, cardiovascular, and psychological consequences of HIV and its treatments.

RESUMEN

BACKGROUND: Ultra-processed foods represent a considerable part of the diet of US children and adolescents, yet their association with total, abdominal, and visceral overweight/obesity remains understudied. OBJECTIVE: To examine associations between dietary contribution of ultra-processed foods and total, abdominal, and visceral overweight/obesity in a nationally representative sample of US adolescents. DESIGN: Cross-sectional analyses were performed on data collected from adolescents participating in the 2011-2016 National Health and Nutrition Examination Survey. PARTICIPANTS/SETTING: Participants included 3587 adolescents aged 12 to 19 years, who had data from at least 1 day of valid 24-hour dietary recall data. MAIN OUTCOME MEASURES: Total overweight/obesity, abdominal overweight/obesity, and visceral overweight/obesity data were collected. STATISTICAL ANALYSES PERFORMED: All food items (grams per day) recorded in the 24-hour recalls were classified according to Nova. Multiple logistic regressions were used to evaluate associations between the dietary contribution of ultra-processed foods (expressed in percentage of total grams per day) and outcomes. Multivariable models were adjusted for sociodemographic covariates, physical activity, total energy intake, whether the individual was following a special diet for weight loss, and indicators of the nutritional quality of the diet. RESULTS: In multivariable analyses, the highest consumption of ultra-processed food was associated with 45%, 52%, and 63% higher odds of total, abdominal, and visceral overweight/obesity, respectively (odds ratio [OR] 1.45, 95% CI 1.03-2.06, P for linear trend = .040; OR 1.52, 95% CI 1.06-2.18, P for linear trend = .026; OR 1.63, 95% CI 1.19-2.24, P for linear trend = .005, respectively), compared with the lowest consumption. A 10% increment in the proportion of ultra-processed foods in the diet was associated with an increased risk of both abdominal overweight/obesity (OR 1.07; 95% CI 1.01-1.13) and visceral overweight/obesity (OR 1.07; 95% CI 1.02-1.13). CONCLUSIONS: Study findings support the growing evidence of cross-sectional and prospective associations between ultra-processed foods and increased adiposity and also with metabolically unhealthy phenotypes of obesity in adolescence. Timely action to reduce the consumption of ultra-processed foods among adolescents is needed.

RESUMEN

Objectives: This study aimed to examine and compare the extent to which different nutrient profile models (NPMs) from Latin America (LA) identify packaged foods and beverages with child-directed marketing sold in Brazil as being high in nutrients associated to the risk of non-communicable diseases (NCDs). Materials and methods: In this cross-sectional study, we evaluated 3,464 foods found in the five largest Brazilian supermarkets. Child-directed marketing was coded using the International Network for Food and Obesity/NCDs Research, Monitoring and Action Support (INFORMAS) protocol. Differences in medians of sugar, saturated fats, and sodium per 100 kcal in foods, with the presence and absence of child-directed marketing, were tested using the Mann-Whitney test. We compared six NPMs in LA and examined to what extent they targeted these products using prevalence ratios. Analyses were performed overall and by the degree of food processing according to the Nova food classification. Results: We found 1,054 packages with child-directed marketing. Among these, candies, cakes and pies, sauces and creams, and sugar-sweetened beverages were significantly higher in sugar, saturated fat, and sodium per 100 kcal than products that are not targeted at children (p < 0.05). Compared with PAHO and the Mexico models, the Brazilian NPMs would allow three times more ultra-processed foods to omit warnings for sodium (p < 0.05). The Uruguayan NPM also flagged fewer ultra-processed foods high in sodium (p < 0.05). The Brazilian model also allows four times more sugar-sweetened beverages and six times more dairy drinks to omit warnings for sugar than the Mexico and PAHO models. In comparison to all other NPMs, the Brazilian model showed the worst performance in identifying baked goods as high in sodium. Chile, Uruguay, and Peru models would also target significantly less sugar-sweetened beverages and high in at least one critical nutrient than PAHO and Mexico models. Conclusion: Compared with other NPMs in LA, the NPM criteria adopted in Brazil are more permissive and less likely to inform consumers of the poor nutritional quality of ultra-processed foods and beverages with child-directed marketing.

RESUMEN

OBJECTIVES: This study aimed to examine associations between consumption of ultraprocessed food (UPF) and C-reactive protein (CRP) levels in a sample of term and preterm infants. METHODS: In this cross-sectional study, 43 preterm infants (<34 wk), chronological age between 9 and 24 mo, were compared with a group of 47 healthy term infants of the same age. Data were collected on dietary intake, anthropometric measures, and serum CRP level (mg/L). The main exposure of interest was the consumption of UPF (excluding all types of milk), measured as the percentage of total energy intake. RESULTS: The mean birth weight, gestational age, and corrected age were 1,245 ± 381.7 g, 29.9 ± 2.3 wk, and 14.3 ± 6.4 mo, respectively, in the preterm group. Infants in the preterm group consumed UPF less frequently (27-67.5% versus 40-87.0%; P = 0.038) but in a greater amount relative to total energy intake (39.8% [19.1-59.1%]) versus 29.0% (14.5- 41.9%; P = 0.040) when compared with the term group. There was no statistically significant difference between the preterm and term groups regarding CRP levels. The consumption of UPF (percentage of energy intake) was independently associated with CRP levels (ß = 0.007; 95% CI, 0.001-0.014; P = 0.034). A significant interaction between being born preterm and UPF consumption was found for CRP levels (P = 0.049). Breast-feeding was not associated with lower consumption of UPF in both groups (24-75.0% versus 43-79.6%; P = 0.404). CONCLUSIONS: There is a positive relationship between UPF and CRP levels among infants, irrespective of excess weight. At the clinical practice level, a better comprehension of the associations between food processing and chronic inflammation may aid in individual dietary guidance.

RESUMEN

This study assessed associations between ultraprocessed food consumption and dietary nutrient profile linked to obesity in children and adolescents in Argentina, Australia, Brazil, Chile, Colombia, Mexico, the United Kingdom, and the United States using nationally representative data collected between 2004 and 2014. Linear regression models were used to evaluate associations between dietary share of ultraprocessed foods (country and age group-specific quintiles and a 10% share increase) and the energy density of diets and their content of free sugars and fiber. Ultraprocessed foods, defined by the NOVA system, ranged from 18% of total energy intake among preschool children in Colombia to 68% among adolescents in the United Kingdom. In almost all countries and age groups, increases in the dietary share of ultraprocessed foods were associated with increases in energy density and free sugars and decreases in fiber, suggesting that ultraprocessed food consumption is a potential determinant of obesity in children and adolescents. Effective global policy action to address growing ultraprocessed food consumption and childhood obesity is urgently needed.

RESUMEN

During COVID-19 pandemic, Italian pediatric oncology departments were obliged to adopt restrictive measures to minimize the risk of in-hospital infections in frail patients and staff members. Access to the wards was significantly reduced and music therapy (MT) activities were suspended. The aim of this study was to compare the level of anxiety and sedation in pediatric patients undergoing invasive procedure before (T1), during(T2) and after(T3) the pandemic, with and without the presence of MT. From January to September 2020, all children aged 2-15 with oncological and hematological diseases undergoing to invasive procedure were enrolled. During T1 and T3 children received preoperative preparation with MT by a certified music-therapist. In T2 they received music or video by clinical staff. Preoperative anxiety scores were measured with the m- YPAS scale. Interviews with mothers were performed. The average consumption of drugs used was analyzed. Significant differences in preoperative anxiety levels between scores in T1, T2 (p.value = 0,0000014) and in T2, T3 (p.value = 0,0000031) were observed. No difference between T1-T3 (p.value = 0,96). Higher dosage of midazolam in T2 (1,14 mg 0,189) compared to T1 (0, 71 mg 0,399) and T2 (1,14 mg 0,189) were observed. Mothers also recorded higher scores on anxiety and stress without music therapy.

RESUMEN

Importance: Reports of associations between higher consumption of ultraprocessed foods (UPF) and elevated risks of obesity, noncommunicable diseases, and mortality in adults are increasing. However, associations of UPF consumption with long-term adiposity trajectories have never been investigated in children. Objective: To assess longitudinal associations between UPF consumption and adiposity trajectories from childhood to early adulthood. Design, Setting, and Participants: This prospective birth cohort study included children who participated in the Avon Longitudinal Study of Parents and Children (ALSPAC) in Avon County, southwest England. Children were followed up from 7 to 24 years of age during the study period from September 1, 1998, to October 31, 2017. Data were analyzed from March 1, 2020, to January 31, 2021. Exposures: Baseline dietary intake data were collected using 3-day food diaries. Consumption of UPF (applying the NOVA food classification system) was computed as a percentage of weight contribution in the total daily food intake for each participant and categorized into quintiles. Main Outcomes and Measures: Repeated recordings of objectively assessed anthropometrics (body mass index [BMI; calculated as weight in kilograms divided by height in meters squared], weight, and waist circumference) and dual-energy x-ray absorptiometry measurements (fat and lean mass indexes [calculated as fat and lean mass, respectively, divided by height in meters squared] and body fat percentage). Associations were evaluated using linear growth curve models and were adjusted for study covariates. Results: A total of 9025 children (4481 [49.7%] female and 4544 [50.3%] male) were followed up for a median of 10.2 (interquartile range, 5.2-16.4) years. The mean (SD) UPF consumption at baseline was 23.2% (5.0%) in quintile 1, 34.7% (2.5%) in quintile 2, 43.4% (2.5%) in quintile 3, 52.7% (2.8%) in quintile 4, and 67.8% (8.1%) in quintile 5. Among those in the highest quintile of UPF consumption compared with their lowest quintile counterpart, trajectories of BMI increased by an additional 0.06 (95% CI, 0.04-0.08) per year; fat mass index, by an additional 0.03 (95% CI, 0.01-0.05) per year; weight, by an additional 0.20 (95% CI, 0.11-0.28) kg per year; and waist circumference, by an additional 0.17 (95% CI, 0.11-0.22) cm per year. Conclusions and Relevance: These findings suggest that higher UPF consumption is associated with greater increases in adiposity from childhood to early adulthood. Robust public health measures that promote minimally processed foods and discourage UPF consumption among children are urgently needed to reduce obesity in England and globally.
