RESUMO

Background/Objectives: Very low birth weight (VLBW) infants may require enhanced nutrition, even during complementary feeding. However, there are limited data on macronutrient intake during this period, particularly concerning the individual timing of the introduction of solid foods in a representative VLBW infant population. Methods: This prospective observational study analyzed macronutrient intake in VLBW infants with a gestational age < 32 weeks based on whether solid foods were introduced early (<17 weeks corrected age (CA)) or late (≥17 weeks corrected age) Nutritional intake was analyzed using a 24 h recall at 6 weeks CA and 3-day dietary records at 12 weeks, 6, 9, and 12 months CA. Results: In total, 115 infants were assigned to the early and 82 to the late group. The timing of solid food introduction did not affect macronutrient intake, except for a lower fat and higher carbohydrate intake (% of energy) in the early group at 12 weeks and 6 months CA: early vs. late, fat-12 weeks: 47.0% vs. 49.0%, 6 months: 39.2% vs. 43.3%; carbohydrates-12 weeks: 44.9% vs. 43.2%, 6 months: 51.3% vs. 48.0%. Apart from docosahexaenoic acid (DHA) and arachidonic acid (AA), dietary intake recommendations were met in both groups. While nutrient intakes varied significantly between breastfed and formula-fed infants, those with comorbidities exhibited similar nutrient intake levels compared to those without. Conclusions: Our findings suggest adequate macronutrient intakes in VLBW infants irrespective of the timing of solid introduction. However, there is a notable need to enhance dietary intakes of DHA and AA. Future research is crucial to assess whether current nutrient intakes are sufficient for VLBW infants with comorbidities.

RESUMO

This study aimed to analyze the association between sociodemographic factors, maternal and neonatal characteristics and the time taken to introduce complementary feeding in low birthweight and preterm newborns. This is a prospective cohort study of 79 preterm newborns weighing less than or equal to 1,800g. Data were collected at the time of hospital discharge and at the 6th, 9th ,and 12th months of corrected gestational age (CGA), using a structured questionnaire to analyze the time taken to introduce complementary feeding and the texture of the foods introduced. Furthermore, the Survey of Well-being of Young Children (SWYC-BR) was used to assess the risk of developmental delay. Cox proportional hazards regression was used to analyze the variables. The introduction of complementary feeding was assessed in preterm newborns based on the median age of introduction of liquid foods (3.50; IQR: 2.50-5.00), followed by solid (4.70; IQR: 3.20-5.20) and soft foods (5.00; IQR: 4.50-5.50). There was also an association with gestational age (RR = 1.25; 95%CI: 1.02-1.52) throughout the process of food introduction. For solid and soft foods, those with the longest length of stay (RR = 1.03; 95%CI: 1.10-1.05) and on mixed breastfeeding (RR = 2.97; 95%CI: 1.24-7.09) delayed the introduction of complementary feeding the longest. For liquid foods, less severe preterm newborns (Score for Neonatal Acute Physiology and Perinatal Extension - SNAPPE II [RR = 0.96; 95%CI: 0.94-0.98]) and mothers who were breastfeeding at hospital discharge (RR = 11.49; 95%CI: 1.57-84.10) delayed the introduction of complementary feeding. Guidelines are needed to better advise professionals and parents and/or guardians on the ideal time to introduce feeding.


O objetivo deste artigo foi analisar a associação entre os fatores sociodemográficos, as características maternas e neonatais e o tempo de introdução da alimentação complementar em recém-nascidos pré-termo e com baixo peso. Trata-se de um estudo de coorte prospectivo feito com 79 recém-nascidos pré-termo com peso menor ou igual a 1.800g. Os dados foram coletados no momento da alta hospitalar e ao 6º, 9º e 12º mês de idade gestacional corrigida (IGC), com auxílio de um questionário estruturado para analisar o tempo de introdução da alimentação complementar e texturas dos alimentos introduzidos. Além disso, para avaliar o risco de atraso de desenvolvimento, utilizou-se o Survey of Well-being of Young Children (SWYC-BR). Para análise das variáveis, aplicou-se regressão de riscos proporcionais de Cox. A introdução da alimentação complementar foi observada nos recém-nascidos pré-termo, com a mediana de idade de introdução de alimentos líquidos (3,50; IQ: 2,50-5,00), seguido por sólidos (4,70; IQ: 3,20-5,20) e pastosos (5,00; IQ: 4,50-5.50). Ainda, verificou-se associação da idade gestacional (RR = 1.25; IC95%: 1,02-1,52) em todo o processo da introdução alimentar. Para os alimentos sólidos e pastosos, aqueles com o maior tempo de internação (RR = 1,03; IC95%: 1,10- 1,05) e em amamentação mista (RR = 2,97; IC95%: 1,24-7,09) adiaram mais o tempo para introduzir a alimentação complementar. Para alimentos líquidos, recém-nascidos pré-termo menos graves (Score for Neonatal Acute Physiology and Perinatal Extension - SNAPPE II [RR = 0,96; IC95%: 0,94-0,98]) e mães que estavam amamentando na alta hospitalar (RR = 11,49; IC95%: 1,57-84,10) postergaram a introdução alimentar. Diretrizes para melhor orientação de profissionais e pais e/ou responsáveis sobre o momento ideal de introdução alimentar se faz necessário.

Además, para evaluar el riesgo de retraso en el desarrollo, se utilizó la Survey of Well-being of Young Children (SWYC-BR). Para analizar las variables, se aplicó la regresión de riesgos proporcionales de Cox. La introducción de la alimentación complementaria se observó en los recém-nascidos pré-termo, con la mediana de edad de introducción de alimentos líquidos (3,50; IIC: 2,50-5,00), seguido de los sólidos (4,70; IIC: 3,20-5,20) y pastosos (5,00; IIC: 4,50-5,50). Además, se constató la asociación de la edad gestacional (RR = 1,25; IC95%: 1,02-1,52) durante todo el proceso de introducción alimentaria. En el caso de alimentos sólidos y pastosos, aquellos con mayor tiempo de hospitalización (RR = 1,03; IC95%: 1,10-1,05) y en lactancia mixta (RR = 2,97; IC95%: 1,24-7,09) retrasaron más la introducción de alimentación complementaria. En el caso de alimentos líquidos, los recém-nascidos pré-termo menos graves (Score for Neonatal Acute Physiology and Perinatal Extension - SNAPPE II [RR = 0,96; IC95%: 0,94-0,98]) y las madres que estaban amamantando al alta hospitalaria (RR = 11,49; IC95%: 1,57-84,10) pospusieron la introducción de alimentos. Se hacen necesarias pautas para una mejor orientación a profesionales y padres o tutores sobre el momento ideal para la introducción alimentaria.

RESUMO

Food safety is an important issue to protect humane health and improve the life quality. Hence, analysis of the possible contaminants in food samples is essential. A rapid and efficient vortexed-assisted dispersive µ-solid-phase extraction coupled with gas chromatography-mass spectrometry was proposed for simultaneous separation/preconcentration and determination of five commonly used organophosphorus pesticides. Reduced graphene oxide decorated NiCo2(OH)6 nanoflowers as a novel nanostructure was synthetized and introduced for separation of the target pesticides from the wheat flour, rice flour, and baby food cereal samples. The characterization of the nanoflowers was accomplished by SEM-EDX, XRD, and FT-IR techniques. The main factors including pH, the amount of nanoflower, the volume of sample solution, salt concentration (ionic strength), desorption conditions (i.e. desorption solvent type and volume, and desorption time) on the pesticides extraction efficiencies were inquired using matrixed match method. Applying the optimum conditions, the linearity of 0.100-500.000 µg kg-1, LODs and LOQs in the range of 0.03-0.04 µg kg-1 and 0.1 µg kg-1 for the studied food samples were obtained. The repeatability (intra-day precision (n = 5)) of ≤ 2.0 % and reproducibility (inter-day precision, days = 5, n = 3) of ≤3.1 % and were appraise at three concentration levels (10, 50 and 100 µg kg-1 of each analyte). High relative recoveries of 90.0-99.3 % ascertained high potential of the presented method for complex matrix analysis.

RESUMO

The aim of the present study was to assess the performance and complementarity of methods capable of both quantifying furan, 2-Methylfuran (2-MF) and 3-Methylfuran (3-MF) in infant foods, but also to comprehensively explore other furan derivatives. It is more particularly a question of validating and comparing the couplings of the two headspace extraction methods most used for the analysis of furan compounds - Headspace Solid Phase Microextraction (HS-SPME) and Static HeadSpace (SHS) - with gas chromatography hyphenated to a high-resolution mass detector (Q Exactive-Orbitrap MS) which allows both targeted quantification and suspect screening. Firstly, the accuracy profile approach was implemented to assess, validate and compare HS-SPME- and SHS-GC-Q Exactive-Orbitrap MS for the quantification of furan in two model infant foods, apple puree and first infant formula. SHS-GC-Q Exactive-Orbitrap MS, showed better accuracy (uncertainty < 17.2 % vs 22.5 % for HS-SPME GC-Q Exactive-Orbitrap MS) and better sensitivity (LOQ < 2.8 vs LOQ < 4.0 µg/kg) over a broader validation range (2-100 µg/kg vs 5-100 µg/kg in apple puree). Secondly, SHS-GC-Q Exactive-Orbitrap MS was assessed and validated by accuracy profile for the quantification of 2-MF and 3-MF, with performance close to those for furan except for 3-MF in apple puree. Thirdly, SHS-GC-Q Exactive-Orbitrap MS was used to quantify the levels of these compounds in 20 commercial samples (n = 3) belonging to the four main categories of infant food (infant formulae, fruit purees, infant cereals, vegetable/fish baby meals). Furan was quantified in 75 % of the samples, with maximum levels in the vegetable/fish-based infant foods (up to 127 µg/kg) while 2-MF and 3-MF were quantified in 45 % and 15 % of products respectively, with maximum levels of 14.1 µg/kg in follow-on formula 3rd age and 9.2 µg/kg in apple puree. Finally, SHS- and HS-SPME-GC-Q Exactive-Orbitrap MS data of the 20 infant products were processed in suspect screening mode using Compound DiscovererTM software. Coupling with HS-SPME, it made it possible to identify 13 additional furan derivatives, i.e. 5 more than with SHS. The relevance and safety status of the compounds identified are discussed.

RESUMO

This study reviews global levels of ochratoxin A (OTA) in infant formula and cereal-based foods, using Monte Carlo simulation to assess risks. The review found 24 studies on global OTA levels in infant food and cereal-based products, using databases including PubMed, Scopus, Web of Science and Embase until March 2024. We estimated OTA exposure in infant food based on concentration, intake and body weight. The exposure and hazard quotient margin were calculated using BMDL10 and TDI values. Monte Carlo simulation evaluated human health risks from OTA in infant formula and cereal-based foods. A global study from 14 countries shows varying levels, surpassing EU limits in Tunisia, Ecuador, the USA, and generally in Africa, notably in infant cereals, which had higher levels than formula. Globally, OTA was present in 29.3% of the 3348 samples analyzed, with Lebanon at 95.2% and Brazil at 0%. Analysis indicates only non-carcinogenic risk for infants. While health risks for infants are mostly low, ongoing research and monitoring are vital to minimize OTA exposure in infant food.

RESUMO

The aim of this study was to investigate whether age at introduction of solid foods in preterm infants influences growth in the first year of life. This was a prospective observational study in very low birth weight infants stratified to an early (<17 weeks corrected age) or a late (≥17 weeks corrected age) feeding group according to the individual timing of weaning. In total, 115 infants were assigned to the early group, and 82 were assigned to the late group. Mean birth weight and gestational age were comparable between groups (early: 926 g, 26 + 6 weeks; late: 881 g, 26 + 5 weeks). Mean age at weaning was 13.2 weeks corrected age in the early group and 20.4 weeks corrected age in the late group. At 12 months corrected age, anthropometric parameters showed no significant differences between groups (early vs. late, mean length 75.0 vs. 74.1 cm, weight 9.2 vs. 8.9 kg, head circumference 45.5 vs. 45.0 cm). A machine learning model showed no effect of age at weaning on length and length z-scores at 12 months corrected age. Infants with comorbidities had significantly lower anthropometric z-scores compared to infants without comorbidities. Therefore, regardless of growth considerations, we recommend weaning preterm infants according to their neurological abilities.

RESUMO

Iron and zinc are important nutrients during infancy, particularly for infants exclusively fed human milk at the beginning of complementary feeding (CF) from 6-12 months. The 1st Foods Study examined the ingredients and nutrient contents of commercially-available infant and toddler foods (ITFs) that were sold in the US and contained meat. Company websites (n = 22) were used to create a database of commercial ITFs (n = 165) available for purchase in the US and contained at least one meat (e.g., beef, chicken, pork). Single ingredient and ready-to-serve meals (for ages ≤ 9 months) and ready-to-serve meals (for ages 10+ months) were categorized as infant and toddler products, respectively. For each product, the ingredient list, intended age/stage, serving size (g), energy (kcal), protein (g), iron (mg), and zinc (mg) per serving were recorded from product labels. Nutrient amount/100 g was calculated for each product and medians and inter-quartile ranges were calculated and compared (1) by intended age/stage of the product and (2) according to meat type. In general, toddler products contained more iron than infant products. Within infant products (n = 65), more iron was found in products containing beef relative to products with other meats, which were similar in iron content. Within toddler products (n = 38), more iron was found in products containing seafood, followed by beef, turkey, and pork. Slightly less iron was found in products with chicken. Zinc content was infrequently reported (n = 17 total products). Because many of the products assessed contained low amounts of iron and zinc, meeting the current infant and toddler requirements for iron and zinc during the CF period may be challenging if commercial ITFs containing meat are the primary source of these nutrients.

RESUMO

Iron deficiency in infants can impact development, and there are concerns that the use of baby food pouches and baby-led weaning may impair iron status. First Foods New Zealand (FFNZ) was an observational study of 625 New Zealand infants aged 6.9 to 10.1 months. Feeding methods were defined based on parental reports of infant feeding at "around 6 months of age": "frequent" baby food pouch use (five+ times per week) and "full baby-led weaning" (the infant primarily self-feeds). Iron status was assessed using a venepuncture blood sample. The estimated prevalence of suboptimal iron status was 23%, but neither feeding method significantly predicted body iron concentrations nor the odds of iron sufficiency after controlling for potential confounding factors including infant formula intake. Adjusted ORs for iron sufficiency were 1.50 (95% CI: 0.67-3.39) for frequent pouch users compared to non-pouch users and 0.91 (95% CI: 0.45-1.87) for baby-led weaning compared to traditional spoon-feeding. Contrary to concerns, there was no evidence that baby food pouch use or baby-led weaning, as currently practiced in New Zealand, were associated with poorer iron status in this age group. However, notable levels of suboptimal iron status, regardless of the feeding method, emphasise the ongoing need for paying attention to infant iron nutrition.

RESUMO

Ochratoxin A (OTA), zearalenone (ZEN), and deoxynivalenol (DON) are mycotoxins whose exposure is associated with various adverse health effects, including cancer and renal disorders, estrogenic effects, and immunosuppressive and gastrointestinal disorders, respectively. Infants (<2 years) are the most vulnerable group to mycotoxins, representing a unique combination of restricted food consumption types, low body weight, lower ability to eliminate toxins, and more future years to accumulate toxins. This study aimed to estimate the infant́s exposure to OTA, DON, and ZEN due to the consumption of milk formula and baby cereals in Chile. Milk formula samples (n = 41) and baby cereals (n = 30) were collected and analyzed using commercial ELISA kits for OTA, DON, and ZEA determination. Exposure was assessed by the Estimated Daily Intake (EDI) approach (mean and worst-case scenario, WCS) with the levels found in a modified Lower Bound (mLB) and Upper Bound (UB); ideal consumption (<6m, 7-12 m, and 13-24 m); adjusted by the weight of each group. The risk was estimated by comparing the EDI with a reference tolerable daily intake or by the margin of exposure (MOE) in the case of OTA. DON and OTA occurrence in infant formula were 34 % and 41 %, respectively. The co-occurrence between these mycotoxins was 22 %. Mycotoxin contents were below LOQ values except for OTA determined in one sample (0.29 ng/ml). No milk formulae were contaminated with ZEN. In the case of baby cereals, the occurrences were 17 % for OTA, 30 % for DON, and 7 % for ZEN, all below LOQ. Co-occurrence was seen in two samples between ZEN and OTA. According to exposure calculations, the MOE for OTA was less than 10,000 in all models for milk formula between 0 to 12 months of age and in the UB and WCS for cereal consumption. Health concerns were observed for DON in the WCS and UB for milk consumption in all ages and only in the UB WCS for cereal consumption. Considering the high consumption of milk formula in these age groups, regulation of OTA and other co-occurring mycotoxins in infant milk and food is strongly suggested.

RESUMO

Consumption of rice-based foods provides essential nutrients required for infants and toddlers' growth. However, they could contain toxic and excess essential elements that may affect human health. The study aims to determine the composition of rice-based baby foods in the USA and outside and conduct a multiple-life stages probabilistic exposure and risk assessment of toxic and essential elements in children. Elemental concentrations were measured using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) in thirty-three rice-based baby foods. This includes 2 infant formulas, 11 rice baby cereals, and 20 rice snacks produced primarily in the United States, China, and other countries. A probabilistic risk assessment was conducted to assess risks of adverse health effects. Results showed that infant formula had higher median concentrations of selenium (Se), copper (Cu), zinc (Zn), sodium (Na), magnesium (Mg), calcium (Ca), and potassium (K) compared to rice baby cereal and rice snacks. On the contrary, rice snacks had the highest median concentration of Arsenic (As) (127 µg/kg) while rice baby cereals showed the highest median concentration of Cd (7 µg/kg). A higher lifetime estimated daily intake was observed for samples manufactured in the USA compared to those from China and other countries. Hazard quotient (HQ < 1) values were suggestive of minimal adverse health effects. However, lifetime carcinogenic risk analysis based on total As indicated an unacceptable cancer risk (>1E-04). These findings show a need for ongoing monitoring of rice-based foods consumed by infants and toddlers as supplementary and substitutes for breast milk or weaning food options. This can be useful in risk reduction and mitigation of early life exposure to improve health outcomes.

RESUMO

Infant cereals, one of the first solid foods introduced to infants, have been reported to pose risks to human health because they contain toxic elements and an excess of essential elements. The objective of this study was to assess the cancer and non-cancer risk of exposure to essential and toxic elements in infant cereal in Brazil. In our analyses, we included data from 18 samples of infant cereals made from different raw materials and estimated the incremental lifetime cancer risks and non-cancer hazard quotients (HQs) for their consumption. Rice cereal is particularly concerning because it is immensely popular and usually contains high levels of inorganic arsenic. In addition to arsenic, we assessed aluminum, boron, barium, cadmium, chromium, copper, lead, manganese, nickel, selenium, silver, strontium, and zinc. The cancer risk was highest for rice cereal, which was also found to have an HQ > 1 for most of the tested elements. Inorganic As was the element associated with the highest cancer risk in infant cereal. All of the infant cereals included in this research contained at least one element with an HQ > 1. The essential and non-essential elements that presented HQ > 1 more frequently were zinc and cadmium, respectively. The cancer and non-cancer risks could potentially be decreased by reducing the amount of toxic and essential elements (when in excess), and public policies could have a positive influence on risk management in this complex scenario.

RESUMO

This manuscript describes the development of a novel liquid phase microextraction (LPME) method for the extraction and determination of Zn (II), Fe (II), Pb (II), and Cd (II) in various infant/baby food and supplements products. The method is based on vortex-assisted extraction combined with a switchable-hydrophilicity solvent (SHS) sample preparation. The SHS, which undergoes reversible phase changes triggered by pH change, enables selective extraction and easy phase separation. A flame atomic absorption spectroscopy was used in the final determination step. Optimization studies revealed, that the optimal pH of the sample solution (after digestion) during analytes extraction is 5.5. A l-proline is added to the sample (375 mM) to ensure the complexation of the target metal cations. After the complexation step, 750 µL of SHS - a N, N-Dimethylcyclohexylamine along with 0.9 mL of 2 M of acetic acid solution is added (hydrophilicity switch-on stage) and mixed manually to obtain a homogeneous solution. In the last stage, 0.45 mL of 10 M NaOH solution (hydrophilicity switch-off stage) is added to the sample solution and a vortex for 100 s is applied to ensure the effective extraction and separation of the complex containing the analytes. At this stage, a cloudy solution is immediately obtained. Finally, the effective phase separation is obtained at the centrifugation step (4000 rpm for 2 mins). The method limit of detection was as 0.03, 0.009, 0.6, and 0.2 ng/L for Zn (II), Fe (II), Cd (II), and Pb (II) respectively with RSD% below 2.0 %. The analysis of certified reference materials and real samples proved the full applicability of the method for routine analysis, contributing to the field of heavy metal analysis and ensuring the safety of baby products. According to the AGREE methodology, this method can be named as green analytical chemistry method with a score of 0.77.

RESUMO

Background: Appropriate infant and young child feeding (IYCF) plays a crucial role in promoting the healthy growth of children. Currently, many Chinese urban parents are seeking care of children from the early childhood education (ECE) institutions, however, little is known about the feeding practices of infants and young children in ECE institutions. This study aims to investigate the complementary feeding practices for Chinese urban children aged 6-23 months in ECE institutions and explore potential factors influencing their feeding practices. Methods: This cross-sectional study was conducted among primary caregivers of children aged 6-23 months in ECE institutions across 31 provinces in China from 1 March to 30 April 2023. Convenience sampling was used to recruit caregivers from centres of Gymboree Play & Music (an ECE institution). Self-administered questionnaires were designed using the online survey tool Sojump and distributed through WeChat platform, which collected information on 1) children's complementary feeding practices; 2) food frequency of seven food groups; 3) caregivers' feeding knowledge and practices; 4) frequency of children attended ECE classes and the primary caregivers' daily nurturing care time; 5) source of information on complementary feeding. Results: A total of 2731 children and their caregivers were surveyed, with 416 children aged 6-11 months and 2315 children aged 12-23 months. The prevalence of minimum dietary diversity (MDD), minimum meal frequency (MMF), and minimum acceptable diet (MAD) was 59.4, 60.6, and 39.2%, respectively. Only 17.3% caregivers believed that continued breastfeeding should be at two years or above, and 29.5% children were continuously breastfed at 12-23 months (CBF). The proportion of non-responsive feeding practices among caregivers ranged from 28 to 64%. Except for CBF, the prevalence of other key complementary feeding practices was higher among children who attending ECE classes than those not attending ECE classes (all P < 0.05). Moreover, children aged 12-23 months who received long-nursing care time (≥4h/d) had significantly higher MMF and MAD prevalence than those in short-nursing care time group (MMF = 66.2 vs. 58.8%, P = 0.0003; MAD = 44.2 vs. 38.3%, P = 0.0047). Conclusions: The complementary feeding practices of children aged 6-23 months in ECE institutions in urban China remained suboptimal, and non-responsive feeding practices among caregivers were common. The attendance of ECE classes and the caregivers' daily nurturing care time could be beneficial in ensuring children to comply with complementary feeding recommendations.

RESUMO

Different types of infant foods categorized as formulas, cereals, and purees imported from seven different countries and available on the Kuwaiti retail market were collected to determine the elemental content, including essential trace elements namely chromium (Cr), manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), selenium (Se), and molybdenum (Mo); potentially toxic trace elements such as aluminum (Al), nickel (Ni), tin (Sn), antimony (Sb), and uranium (U); and toxic trace elements including arsenic (As), lead (Pb), cadmium (Cd), and mercury (Hg). The samples were analyzed using ICP-MS. An extensive literature search illustrated the uniqueness of this study since seven different essential elements, five different potentially toxic elements, and four different toxic trace elements were measured in a variety of infant foods; in addition, the different trace etlemental levels measured in the investigated infant foods were compared to the ones associated with the different infant foods types reported in the literature. The essential trace element concentrations detected in this study were implemented to calculate their total daily intake, where the calculated daily intake values were compared to their recommended dietary allowance (RDA) to assess the percentage total daily intake for the essential trace elements. Further, the calculated potentially toxic and toxic trace elements daily intake values were used to assess the potential health risks to infants incurred by consuming different infant foods by calculating the hazard quotient (HQ), while the margin of exposure (MOE) was calculated for the toxic ones only. It was concluded that infant formulas and foods should be added to the infant diet in addition to breast milk to meet specific nutritional needs. This study confirms that infants are exposed to toxic trace elements via diet, warranting careful attention to diet choices both to limit this exposure and to avert potentially hazardous adverse health effects to the infants. However, based on the calculated hazard quotients (HQs) and margin of exposures (MOEs), consuming breast milk in addition to almost all different types of infant foods is considered safe and unlikely to contribute to infants' non-cancerous health hazards.

RESUMO

Introdução: A influência do consumo de composto lácteo na nutrição de crianças em primeira infância ainda é desconhecida, apesar de o produto movimentar um mercado multimilionário. Objetivo: Avaliar a composição nutricional do composto lácteo e a influência de seu consumo sobre as necessidades diárias de macronutrientes e energia de crianças pequenas. Métodos: A pesquisa foi dividida em três partes, sendo: a) avaliação da composição nutricional e ingredientes; b) comparação do composto lácteo brasileiro com uma proposta de padronização; c) cálculo de inadequação nutricional e influência do consumo de composto lácteo em crianças pequenas. Resultados: Foi possível categorizar o produto em três subgrupos, de acordo com os ingredientes, sendo: grupo 1 (soro de leite, açúcar e gordura vegetal), grupo 2 (adição de vitaminas e minerais) e grupo 3 (ampla lista de ingredientes, sem adição de açúcares e adição de bioativos). De forma geral, o composto lácteo tem como características: excesso de proteínas e açúcares de adição, predominância de gorduras saturadas, além de aditivos químicos. Em comparação com a proposta de composição ideal, o composto lácteo brasileiro excede todos os nutrientes analisados e, por fim, o consumo de dois copos de 200mL de composto lácteo por dia corresponde a 100% das necessidades diárias de proteína, sendo as crianças de 0 a 11 meses as mais prejudicadas. Conclusão: Independentemente do subgrupo e do ingrediente, o produto tem impacto negativo na saúde infantil, e quanto menor a idade de introdução, maior o impacto na saúde, podendo levar ao desenvolvimento de sobrepeso e obesidade.


Introduction: The influence of consuming growing-up milk on the nutrition of infants is still unknown, despite the product driving a multimillion-dollar market. Objective: To evaluate the nutritional composition of the growing-up milk and the influence of its consumption on the daily macronutrient and energy needs of young children. Methods: The research was divided into three parts, namely: a) evaluation of nutritional composition and ingredients; b) comparison of the Brazilian growing-up milk with a proposed standardization; c) calculation of nutritional inadequacy and the influence of growing-up milk consumption in young children. Results: It was possible to categorize the product into three subgroups based on ingredients, namely: group 1 (whey, sugar, and vegetable fat), group 2 (added vitamins and minerals), and group 3 (a wide range of ingredients, no added sugars, and addition of bioactives). Overall, the growing-up milk is characterized by excess protein and added sugars, a predominance of saturated fats, and the presence of chemical additives. Compared to the proposed ideal composition, the Brazilian growing-up milk exceeds all analyzed nutrients. Finally, consuming two 200mL glasses of growing-up milk per day corresponds to 100% of daily protein needs, with children aged 0 to 11 months being the most affected. Conclusion: Regardless of the subgroup and ingredient, the product has a negative impact on children's health, and the younger the age of introduction, the greater the impact on health, potentially leading to the development of overweight and obesity.

RESUMO

BACKGROUND: With the widespread consumption by children of cereal-based baby food, acrylamide contamination is a prevalent risk that may have carcinogenic consequences. OBJECTIVE: This study aims to develop and validate a modified QuEChERS protocol (quick, easy, cheap, effective, rugged, and safe) without solvent exchange, followed by rapid separation and accurate determination of acrylamide in cereal-based baby foods using reversed-phase (RP)-LC-MS/MS. METHODS: Samples were extracted using a modified QuEChERS protocol of the AOAC version and cleaned up with basic alumina. Separation was performed on a Phenomenex® Kinetex C18 column (100 Å × 3.5 µm × 4.6 mm × 150 mm) using a gradient elution program with a mobile phase of 10 mM ammonium formate-methanol. Determinations were conducted using electrospray ionization (ESI)-MS/MS in positive-ion mode. RESULTS: Basic alumina yielded clean extracts, resulting in acceptable recovery percentages and a tolerable matrix effect (ME) <5%. This allowed extraction without a solvent exchange step. Efficient separation was achieved at a retention time (tR) of 3.39 ± 0.05 min employing an RP-C18 column with core-shell properties in a relatively short analysis run time of only 5 min. Trueness, precision, LOD, LOQ, linearity range, and R2 results were 92.5-104.6%, RSD ≤12.2%, 5 µg/kg, 20 µg/kg, 4.0-1000.0 µg/kg, and > 0.9999, respectively. The test method applicability was demonstrated by proficiency testing (PT) and 50 real samples of cereal-based baby foods. Most of the tested samples were in violation of acrylamide's established European Union benchmark (40 µg/kg). CONCLUSION: Acetate-buffered QuEChERS protocol in conjunction with optimized amounts of basic alumina was confirmed as an efficient extraction protocol for acrylamide from cereal-based baby foods resulting in optimal method performance. Successful selection of the RP-C18 column is key for selective separation for acrylamide in a relatively short analysis run time. HIGHLIGHTS: The modified AOAC QuEChERS protocol with a dispersive solid phase extraction (d-SPE) of basic alumina assisted in reducing the ME to tolerable levels while maintaining acceptable method performance. The use of an RP-C18 column with core-shell properties enabled a rapid and accurate acrylamide determination.

RESUMO

Synthetic phenolic antioxidants (SPAs) are a group of ubiquitous contaminants with multiple toxicities. However, current knowledge on the occurrence of SPAs in baby food and associated infant exposure is lacking. Herein, we analyzed three categories of baby food from China: infant formula, cereal, and puree, for a broad suite of 11 traditional and 19 novel SPAs. In addition to 11 traditional SPAs, up to 13 novel SPAs were detected in the baby food samples. The median concentrations of novel SPAs for infant formula, cereal, and puree were 604, 218, and 24.1 ng/g, respectively, surpassing those of traditional SPAs (53.4, 62.1, and 10.0 ng/g). The prevalent SPAs in the samples were butylated hydroxytoluene, 2,4-di-tert-butylphenol, pentaerythritol tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate] (AO 1010), and octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate (AO 1076). Source analysis indicated that the prevalence of these four SPAs in baby food was associated with contamination of packaging materials, mechanical processing, or raw ingredients. Migration experiments demonstrated that contamination of plastic packaging constituted an important source. Exposure assessment suggested that there may be no appreciable health risk posed by the SPAs in baby food. Even so, baby food consumption was still a dominant pathway for infant exposure to SPAs, with a higher contribution than breast milk consumption, dust ingestion, dermal dust absorption, and air inhalation, which requires special attention.

RESUMO

Baby Foods (BFs) and Infant formulas (IFs) are the main sources of nutrition for an infant throughout the 1st year of life. Various enriched products are commercially available for parents seeking to fulfill their baby's nutritional needs. Consequently, different bioactive lipids are present in BFs and IFs, including dietary oxysterols (DOxS), whose known toxicity has been associated with mutagenicity, cancer, and other chronic diseases. In this work, we performed an exposure assessment of 25 bioactive lipids on IFs (n = 30) and BFs (n = 13) commercially available in the US. To determine dietary exposure, we used EPA's SHEDS-HT probabilistic model. Even though ß-Sitosterol was the most exposed bioactive lipid with 75,410 µg/day, cholesterol was the most absorbed compound during the entire first year (19.3 mg/day). Additionally, we found 7α-hydroxycholesterol (7α-OH) as a potential DOxS biomarker of the BFs manufacturing process. This is the first time an infant's exposure assessment (including DOxS) after BFs and IFs consumption is performed, enabling much-needed information regarding these hazardous compounds and their potential effects on infants' health.

RESUMO

OBJECTIVE: To assess infant and young child feeding (IYCF) practices in Lebanon and investigate their associations with socio-demographic and lifestyle factors. DESIGN: A cross-sectional national survey was conducted in 2012-2013. In addition to a socio-demographic and lifestyle questionnaire, a 24-h dietary recall for the children was collected, with mothers as proxies. IYCF practices were assessed based on the 2021 indicators of the WHO. SETTING: Lebanon. PARTICIPANTS: Children aged 0-23 months and their mothers (n 469). RESULTS: While the majority of infants were ever breastfed (87·6 %), the prevalence of exclusive breast-feeding (BF) in those under 6 months of age was 11·0 %. Early initiation of BF was 28 %. A greater child's birth order, partner's support for BF, higher parental education, maternal BF knowledge and non-smoking were associated with higher odds of meeting BF recommendations. As for complementary feeding, 92·8 % of children (6-23 months) met the minimum meal frequency indicator, 37·5 % met the minimum dietary diversity (MDD) and 34·4 % met the minimum adequate diet (MAD). The consumption of unhealthy food was observed amongst 48·9 % of children, with nearly 37 % consuming sweet beverages. Older maternal age and maternal overweight/obesity were associated with lower odds of meeting MDD and MAD, while child's age and partner's support for BF were associated with higher odds. CONCLUSIONS: The results documented suboptimal IYCF practices amongst Lebanese children and identified a number of factors associated with these practices. Findings from this study will help guide the development of culture-specific programmes aimed at improving IYCF practices in Lebanon.

RESUMO

-A construção dos hábitos alimentares infantis pode ser influenciada pela disponibilidade dos alimentos presentes nos domicílios. Não se sabe o quanto os pais modificam seu padrão de compra de alimentos para mais saudáveis quando há crianças em casa. Esta informação é importante para avaliar a percepção dos pais sobre a influência do ambiente domiciliar na formação de hábitos alimentares saudáveis em seus filhos. A renda familiar é uma variável que pode ter efeito na modificação dos hábitos alimentares dos pais, uma vez que reflete os recursos financeiros disponíveis para compra de alimentos. Investigar a aquisição de alimentos no Brasil em dois períodos com dez anos de diferença possibilita avaliar o efeito macroeconômico do engajamento dos pais na alimentação de seus filhos, uma vez que o país experimentou momentos econômicos distintos na última década. A fim de comparar a aquisição de alimentos saudáveis e não saudáveis em domicílios com e sem crianças no Brasil este estudo utilizou os dados da Pesquisa de Orçamentos Familiares (POF) conduzidos pelo IBGE, no Brasil, em seus inquéritos de 2008-2009 e 2017-2018. Os domicílios foram classificados em: i) presença ou não de crianças de um a cinco anos de idade e ii) maiores de cinco anos até dez anos de idade. Foram considerados todos os domicílios que compunham as amostras: 55.970 (POF 2007-2008) e 69.660 (POF 2017-2018), sem distinção por macrorregião ou zona urbana e rural, assim representando todo o território brasileiro. Os grupos de alimentos utilizados foram constituídos a partir das adaptações de agregados estipulados pela POF nas duas edições do inquérito. Foram estimadas as médias per capita em quilogramas da aquisição (Kg) de frutas, vegetais, refrigerantes e biscoitos num período de 7 dias consecutivos (uma semana). As diferenças das médias per capita da aquisição (Kg) dos alimentos entre domicílios com e sem criança foram estimadas por modelos de regressão de duas partes, combinando um modelo de regressão logística e um modelo linear generalizado de distribuição gama para valores positivos de aquisição, em função da distribuição assimétrica e inflada de zeros para compra de alguns itens alimentares. As análises foram estratificadas por quartos de renda domiciliar per capita, com ajustes pelo sexo e idade do morador de referência do domicílio, número de bebês, adolescentes, adultos e idosos vivendo no domicílio, e gasto mensal com alimentação. A comparação entre as médias de aquisição de alimentos entre os domicílios com e sem crianças foi dada pela intersecção dos intervalos de confiança de 95% e levou-se em consideração o peso amostral e o desenho complexo das POF. A média de aquisição de frutas em 2008-2009 foi maior nos domicílios com crianças das duas faixas etárias nos domicílios mais pobres. Em 2017-2018, a média de aquisição de frutas foi maior entre os domicílios com crianças de cinco a dez anos de idade pertencentes aos estratos socioeconômicos mais ricos. A compra de vegetais diferiu para menos em domicílios com crianças de 5-10 anos nos dois períodos. Houve uma maior média de aquisição per capita de biscoitos nos domicílios com crianças de todas as classes de rendimentos, em ambos os períodos avaliados.


The construction of children's eating habits can be influenced by the availability of food at the home. It's not known how much parents change their pattern of food purchase when there are children at household. That information is important in order to assess parents' perception of the home environment influence in the construction of healthy eating habits at their children. It's possible that family income have an effect on parents' eating habits, once reflects the financial resources available to food purchase. Investigating the food purchase in Brazil in two periods with ten years of diference leads to assess the macroeconomic effect of parental engagement in children's eating habits, since the country has experienced different moments in the last decade. In order to compare the food disponibility in households with and without children, this study utilized data from the Household Budget Surveys (POF) conducted by the Brazilian Institute of Geography and Statistics (IBGE), in Brazil, surveys 2008-2009 and 2017- 2018. The households were categorized into: i) presence or not of children aged between one and five years old and ii) children aged five and ten years old. The sample considered was 55,970 (POF 2007-2008) and 69,660 (POF 2017-2018). The food groups used were constituted from the recommendations of aggregates previously stipulated by the POF in the two editions of the survey. The means per capita were calculated in kilograms of purchase (Kg) of fruits, vegetables, soft drinks and cookies, over a period of 7 consecutive days (one week). Diferences in of food means per capita purchase (Kg) between households with and without children were estimated by using two-part regression models, that combines a logistic regression model and a generalized linear model with gamma distribution for positive values ​​of purchase, in function of the asymmetric and zero-inflated distribution for purchase of some food items. The analyzes were stratified by income quartiles per capita. With adjustments for sex and age of the household's main resident, number of babies, adolescents, adults and elderlys living in the household, and monthly expenditure on food purchase. The comparison between the means of food purchase between households with and without children was given by the intersection of the 95% confidence intervals, considering the weight sample. The means per capita purchase (Kg) of fruit in 2008-2009 was higher in households with children of both age groups in the poorest households. In 2017-2018, the average purchase of fruit was higher among households with children between five and ten years of age belonging to the elevates socioeconomic stratas. The purchase of vegetables were less in households with children aged 5-10 years in both periods. There was a higher purchase of cookies in households with children of all income classes, in both periods.
