This article assesses nutritional intake and adequacy in children with autism spectrum disorder (ASD), subdiagnostic autistic symptoms and children with typical development (TD). In total, 77 children diagnosed with ASD, 40 with subdiagnostic autistic symptoms and 333 children with TD were assessed. A validated food frequency questionnaire was used. Very few nutritional differences were found between ASD and TD groups. Preschool children with ASD and subdiagnostic autistic symptoms had slightly lower intake of monounsaturated fatty acids (MUFA), vitamin D and vitamin B12, and primary school children with ASD and subdiagnostic autistic symptoms had slightly higher intake of protein, cholesterol, thiamine and niacin, and a higher percentage of obesity than children with TD. All samples had an unbalanced energy intake (high in added sugars, fats and saturated fatty acids (SFAs); extremely inadequate intake (80%--100%) of vitamins D and E; high intake (50%-80%) of fibre, b-carotene (except preschool children with TD), calcium (except preschool children) and magnesium). The fact that differences between diagnoses are scarce may be related to the low level of ASD severity in this school sample.

Background: The balance of omega-6/omega-3 (n-6/n-3) is crucial for proper brain function as they have opposite physiological roles. Objectives: To analyze the association between maternal serum ratios of n-6/n-3 in the first and third trimesters of pregnancy and the neurodevelopment of their children in the early days after birth in the population of Northern Spain's Mediterranean region. Methods: Longitudinal study in which 336 mother–child pairs participated. Mother serum concentrations of long-chain polyunsaturated fatty acids (LCPUFAs), docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), and arachidonic acid (ARA) were determined. Sociodemographic, clinical, lifestyle habits, and obstetrical variables were collected. The Bayley Scales of Infant and Toddler Development (BSID-III) was used to assess infant neurodevelopment. Multiple linear regression models adjusting for confounding factors were performed. Results: In the third trimester, a higher maternal n-6/n-3 ratio was negatively associated with infant motor development (β = −0.124, p = 0.023). Similarly, higher ARA/DHA ratios were negatively associated with total motor (β = −2.005, p = 0.002) and fine motor development (β = −0.389, p = 0.001). No significant associations were observed in the first trimester nor for the ARA/EPA ratio in the third trimester. Conclusions: Our findings indicate that an elevated n-6/n-3 ratio and ARA/DHA ratio in the third trimester of pregnancy are associated with poorer motor development outcomes in infants. These results highlight the importance of optimizing maternal fatty acid balance during pregnancy to support fetal neurodevelopment, suggesting a need for further research to verify these associations and elucidate underlying mechanisms.

Mental health problems are highly prevalent in childhood and adolescence and may be associated with nutritional intake. It has recently been shown that a high percentage of infants and children consume large amounts of free sugars. In this paper, we analyse the relationship between free sugar consumption at 12 and 30 months and the risk of developing psychological problems at 30 months in a community sample of 86 children evaluated longitudinally. Socio-family and anthropometric data, and the amount of free sugars consumed were collected at both ages. At 30 months, the Child Behavior Checklist 1.5–5 was administered to parents and an interview was conducted to identify psychological disorders in accordance with DC: 0–3's classification. We report a relationship between high free sugar consumption at 30 months and the concurrent presence of sleeping problems, ADHD and anxiety symptoms. However, no significant association was observed between free sugar consumption at 12 months and the subsequent development of psychological problems. Early detection of emotional and behavioural manifestations and high sugar consumption in children may help to prevent the persistence of psychological problems. [ABSTRACT FROM AUTHOR]

There is an increasing prevalence of psychological issues in childhood. Lifestyle factors during pregnancy, including maternal nutrition, have been linked to children's behavioural development. This study aims to assess the impact of adherence to the Mediterranean diet during pregnancy on the behavioural problems of children at the age of 4. A total of 231 mother‐child pairs were assessed. Maternal adherence to the Mediterranean diet during pregnancy was estimated using a relative Mediterranean Diet Score (rMED). Behavioural outcomes were evaluated through the Child Behaviour Checklist 1½−−5, Teacher's Report Form 1½−5, and Behaviour Rating Inventory of Executive Function—Preschool Version questionnaires. The results indicated that a higher rMED score during pregnancy was associated with a reduced probability of obtaining a clinical score for total problems (OR = 0.42; 95% IC from 0.21 to 0.85), including externalising (OR = 0.29; 95% IC from 0.14 to 0.62), attention problems (OR = 0.32; 95%IC from 0.15 to 0.70), attention‐deficit/hyperactivity problems (OR = 0.36; 95% IC from 0.15 to 0.87), oppositional defiant problems (OR = 0.06; 95% IC from 0.06 to 0.75), and depressive problems (OR = 0.38; 95% IC from 0.15 to 0.96). This study highlights the importance of maternal diet, especially Mediterranean diet, during gestation for proper child development. Key messages: Maternal nutrition during pregnancy has a significant impact on children's development.Previous studies showed that prenatal adherence to the Mediterranean diet is associated with beneficial outcomes for both mother and foetus and in children's development outcomes.Adhering to a Mediterranean diet during pregnancy is related to lower behavioural problems, especially externalising and attention‐deficit hyperactivity disorder, and psychological problems such as depression, in children at 4 years of age.Attention should be directed towards maternal nutrition during the prenatal period to ensure proper child neurodevelopment, encouraging mothers to follow healthy nutritional habits.

Prenatal exposure to dietary toxicants is linked to neurocognitive issues, but its effect on early emotional and behavioral development in children is less clear. To explore the relationship between prenatal intake of As, iAs, Cd, MeHg, Pb, PCDD/Fs, DL-PCBs, and NDL-PCBs and emotional and behavioral issues in four-year-old children. This study included 192 mother–child pairs from the ECLIPSES study, assessing prenatal dietary toxicant exposure through a food-frequency questionnaire and Catalan Food Safety Agency data. Children's emotional and behavioral scores were evaluated using the Child Behavior Checklist for ages 1.5–5 years. Multivariable regression and logistic models were used, focusing on iAs after finding significant preliminary associations. Increased prenatal dietary intake of iAs was associated with internalizing, externalizing, and attention-deficit/hyperactivity problems. Higher iAs levels (>4.16 μg/day) significantly increased the risk of total problems (OR = 2.94) and specific issues like anxious/depressed (OR = 4.88), anxiety (OR = 3.27), and oppositional defiant problems (OR = 4.30). High iAs consumption correlated with the intake of meat, eggs, cereals, tubers, fruits, and pulses Prenatal dietary iAs exposure is associated with various emotional and behavioral problems in children. Monitoring and reducing iAs levels in food are crucial for public health. [ABSTRACT FROM AUTHOR]

Introduction: Introduction: validated food frequency questionnaires in children are scarce, mostly long, and only provide data about food consumption. Objectives: the aim of this study was to evaluate the reproducibility and validity of a short food frequency questionnaire that estimates energy, nutritional intake, and the frequency of food consumption in children aged between 3 and 6 years. Material and methods: in 49 children (57% boys), the reproducibility and validity of a frequency questionnaire with 41 items was assessed using Spearman's and intraclass correlations, both adjusted and not adjusted for energy. A 6-day record was used as a reference method. Results: reproducibility was high in food groups with correlations > 0.70 for most of them and between 0.5 and 0.7 for meat, fish, potatoes, sweets/soft drinks, and oil. For energy and nutrients correlations were > 0.9 and > 0.7, respectively. Validity was strong to moderate for foods with correlations > 0.7 (dairy and milk) and between 0.4 and 0.7 (sausages, eggs, yogur/cheese, vegetables and oil), and for nutrients with correlations > 0.5 (lipids, AGS, AGP, phosphorus, calcium, vitamin E and vitamin C) and between 0.3 and 0.5 (energy, starches, fiber, MUFA, cholesterol, sodium, magnesium, potassium, retinol, riboflavin, niacin, pantothenic acid, vitamin B6 and folates). All correlations were significant and increased after they had been adjusted for energy. Conclusions: the short food frequency questionnaire for children between 3 and 6 years old has high reproducibility and good validity with results that are as good as those of long food frequency questionnaires.

Pregnancy and post-partum are critical periods in which nutritional intake is essential to maternal and child health. Our aim was to describe dietary intake during pregnancy and post-partum and assess its adequacy. A longitudinal study was conducted on 793 pregnant women. Data about maternal characteristics, health, diet and lifestyle were assessed. Energy and nutritional intake were compared to the Recommended Dietary Allowances (RDA). The results showed that the intake of energy (82.6%), protein (80.6%) and carbohydrate (99.5%) was adequate (above 80% of RDA) during pregnancy, as were vitamins C, B2 and B12; but vitamin D, iron and folate intake were a long way from RDA (below 35%). Similar results were observed for the post-partum period although fiber, and vitamins E and C decreased compared to intake during pregnancy. In conclusion, although nutritional requirements increase during gestation, pregnant women did not increase their energy and nutritional intake during pregnancy and postpartum and they had a high risk of deficient intake of vitamin D, iron and folates during pregnancy, and therefore, of developing an unfavorable nutritional status, contrary to health recommendations. These findings underscore the necessity of intensive nutrition programs during and after pregnancy. [ABSTRACT FROM AUTHOR]

Inadequate maternal diet can adversely affect mother and child. Our aim was to assess adherence to the Spanish dietary guidelines and to the Mediterranean diet, to analyze changes in diet during pregnancy and post-partum, and to identify maternal factors associated with food consumption. A total of 793 healthy pregnant women were recruited during the first prenatal visit and followed until the post-partum period. Data from the clinical history, anthropometric measurements, and lifestyle habits were collected. Food consumption was evaluated using a food frequency questionnaire. The results show that in pregnant women the consumption of healthy foods did not meet recommendations, whereas consumption of red and processed meat and sweet food exceeded recommendations. The results also show a medium adherence to the Mediterranean diet that remained unchanged throughout pregnancy. A significant decrease was observed in the consumption of fruits, followed by vegetables and then salted and sweet cereals from pregnancy to post-partum. A better adherence to the Mediterranean diet has been reported by pregnant women that are older, of higher social class, and higher education level, and who do not smoke nor drink (p < 0.005). In conclusion, the diet of pregnant women from Spain departs from recommendations, medium adherence to the Mediterranean diet was maintained throughout the pregnancy and post-partum, and a decreasing consumption of healthy food from the first trimester to the post-partum period was observed. Maternal factors such as age, social class, education, and smoking influence diet quality. [ABSTRACT FROM AUTHOR]

Background: Mental health problems often begin in early childhood and could predict psychiatric and behavioral outcomes. Prenatal factors such as maternal nutrition have an impact on neurodevelopment. This study aims to investigate the association between maternal dietary patterns and emotional and behavioral problems in 4-year-old children., Methods: Within a cohort of 205 mother-child pairs, three maternal dietary patterns were identified: 'Sweet and Superfluous', 'Fish and Vegetables' and 'Meat and Cereals'. Child behavior was evaluated by means of the Child Behavior Checklist 1.5-5 (CBCL 1.5-5), the Teacher's Report Form 1.5-5 (TRF 1.5-5), and the Behavior Rating Inventory of Executive Function - Preschool Version (BRIEF-P). Multivariable analysis determined associations between maternal dietary patterns and their children's behavior., Results: Maternal adherence to the 'Sweet and Superfluous' pattern was positively associated with externalizing and depressive problems in children. The 'Meat and Cereals' pattern was linked to a higher risk for attention, hyperactivity and depressive problems as somatic complaints. Conversely, the 'Fish and Vegetables' pattern was associated with a reduced risk of hyperactivity problems. All these associations were more pronounced in girls than in boys., Conclusions: Maternal diet during pregnancy is associated with the emotional and behavioral development of children at 4 years of age., Impact: Previous research on prenatal dietary patterns and children's behavior is inconclusive. In our study, children of mothers who had higher intakes of sugar and processed foods during pregnancy were more likely to have emotional and behavioral problems at age 4, especially girls. A high-quality diet characterized by fish and vegetable consumption during pregnancy was associated with reduced anxiety and hyperactivity problems in girls. Our findings highlight the importance of prenatal nutrition for child neurodevelopment., (© 2024. The Author(s), under exclusive licence to the International Pediatric Research Foundation, Inc.)
