ObjectiveTo assess the relationship between the degree of severity of eating disorders (ED) and energy and nutrient intakes and nutritional risk in a mixed-sex adolescent population without clinical symptoms.DesignCross-sectional study.SettingData were collected in schools.SubjectsAdolescents (n 495) aged 14·2 (sd 1·0) years. The Eating Attitudes Test was used to detect adolescents at risk of ED (rED) and a structured interview based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, was used to diagnose eating disorder not otherwise specified (EDNOS). Dietary intake was quantified using the 24 h recall method over three days and the probability of inadequate intake was determined.ResultsFemales presented lower intakes of energy, macronutrients and micronutrients (Ca, Fe, Mg, K, P, Na, thiamin, vitamins E, C, B6, B12, pantothenic acid, folic acid) because the severity of their ED was greater. These lower dietary intakes led to nutritional risk (for Ca, Fe, Mg, P, vitamins A, D, B6) in more than 80 % and 60 % of females with EDNOS and rED, respectively. The multiple linear regression models showed that the rED and EDNOS groups presented a lower energy intake of 1597·4 kJ/d (381·8 kcal/d) and 3153·0 kJ/d (753·6 kcal/d), respectively. In contrast, little difference was observed in the nutritional intakes of males.ConclusionsThe female adolescents showed lower energy and nutrient intakes as the ED became more severe, which led to energy, vitamin and mineral deficiencies in a high percentage of females with ED. These nutritional risks could hinder adequate physical and psychological development and lead to chronic ED. [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.

Introduction: Background: eating disorders are a group of conditions in which negative beliefs about food, body shape, and body weight together with behaviors such as restricted food intake, binge eating, excessive exercise, self-induced vomiting, and use of laxatives. They can become serious, affect quality of life, and lead to multiple physical and even psychiatric complications with a fatal outcome. The purpose of this chapter is to describe the characteristics, epidemiology, and trends of eating disorders with updated information based on the most recent publications. Methods: we conducted a systematic literature search in Medline, EMBASE, Cochrane, and Web of Science. The search terms were "anorexia nervosa", "bulimia nervosa", "binge eating disorders" and "epidemiology" both in titles and in abstracts. Results and conclusions: EDs generally occur in adolescents and young adults. The best characterized TCAs are anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (TA). Prevalence studies indicate wide differences by age group and sex, much higher in young women (NA, 0.1-2 %; BN, 0.37-2.98 %; BED, 0.62-4.45 %). The prevalence of EDs is 2.2 % (0.2-13.1 %) in Europe, 3.5 % (0.6-7.8 %) in Asia, and 4.6 % (2.0-13.5 %) in America. Comorbidity is high with psychiatric problems such as depression, anxiety, attention deficit/hyperactivity disorder, obsessive-compulsive disorder, and personality disorders. [ABSTRACT FROM AUTHOR]

Background: Adolescence is a period of vulnerability regarding the emergence of internalizing disorders such as anxiety. Anxiety symptoms can persist into adulthood and involve negative outcomes. The aim of the study was to examine the developmental trajectory of several anxiety subtypes by gender, in a non-clinical sample of early adolescents over three phases. Method: Using a prospective design, 1514 children (mean-age = 10.23, SD = 1.23) underwent anxiety and depression screening in the first phase. Then, 562 children (mean-age = 11.25, SD = 1.04) participated in the second phase, and 242 (mean-age = 13.52; SD = .94) were followed up in the third phase. The Screen for Child Anxiety Related Emotional Disorders was administered in all phases. Developmental trajectories of anxiety scores were examined using latent growth modelling. Results: Manifestations of social phobia and generalized anxiety disorders remained stable. Gender differences were found: boys showed a significant decrease in the developmental trajectories of somatic/panic symptoms, separation anxiety disorder and total anxiety in comparison to girls. Conclusions: The data indicate that anxiety symptomatology is a significant clinical phenomenon in school-age children but that it does not increase throughout early adolescence. It is important to identify developmental patterns for anxiety subtypes and in relation to gender. [ABSTRACT FROM AUTHOR]

Lay Abstract: Autistic individuals face a higher risk of various forms of victimization throughout their lives, with bullying being especially prevalent during their school years. Previous studies indicate that autistic children are 2.4 times more likely to be bullied than their typically developing peers and twice as vulnerable as those with other disabilities. However, the extent of this issue among Spanish schoolchildren with autism remains unexplored. In addition, there is no information regarding the presence of bullying victimization in children with marked but undiagnosed autistic traits (i.e. subthreshold autistic traits). This study examines the self-reported prevalence of bullying victimization in autistic pre-adolescents and those with subthreshold autistic traits, comparing them with peers without neurodevelopmental conditions. The study involved 323 participants (11 and 12 years old; 45 with autism or subthreshold autistic traits) from Spanish general education schools. The results revealed a higher rate of bullying victimization among autistic participants (58%; 3.1 times higher risk) and those with subthreshold autistic traits (27%; 1.5 times higher risk) compared with their peers without neurodevelopmental conditions (18.3%). Victimization was linked to more intense restrictive behaviours and increased behavioural and emotional problems. No significant associations were found with other individual or family factors. Our findings underscore the heightened risk of bullying faced by autistic pre-adolescents and those with subthreshold autistic traits at school, emphasizing the need to identify and implement preventive measures to mitigate bullying and its detrimental impact on their mental well-being and overall quality of life., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article.

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.)

Autism and attention deficit hyperactivity disorder (ADHD) comorbidity in the school population have been understudied. This study estimates its prevalence considering both parents' and teachers' reports and clinical diagnosis. Sociodemographic, clinical, and cognitive data were compared by diagnostic groups: autism, ADHD, autism and ADHD, subthreshold autism spectrum disorder (ASD), subthreshold ADHD, and children without neurodevelopmental conditions. Following a two-phase design, 3727 parents and teachers (1802 preschoolers, 1925 school-age children) participated in the first phase. Subsequently, 781 participants underwent individual assessment for DSM-5 diagnoses. The estimated prevalence of the comorbid diagnosis was 0.51% (0.28%-0.74%), with significant sex differences (0.16% girls, 0.89% boys). The cooccurrence of symptoms of autism and ADHD reported by parents or teachers was 3.2% and 2.6%, respectively. ADHD comorbidity was observed in 32.8% of autistic children and 31.4% of those with subthreshold ASD. ASD comorbidity was observed in 9.8% of children with ADHD and 5.7% of those with subthreshold ADHD. Comorbidity was reported by at least one informant in 95% of children. Only 15.8% of children with autism and ADHD had been previously diagnosed with both conditions. Early detection and accurate comorbidity diagnosis are crucial to address the clinical and socio-educational needs of these children., (© 2024 The Authors.

Background and Objective: Tobacco during pregnancy affects the health of the newborn. The aim was to assess the effect of maternal exposure to active and passive tobacco and of smoking cessation on the risk of preterm deliveries and birth weight, taking into account other risk factors., Patients and Method: Longitudinal study conducted in 282 healthy pregnant women. General, obstetrical and hematological data were collected as it was the smoking habit during pregnancy. Pregnant women were classified as "exposed to smoke" (active smoker and passive smoker) and "unexposed to smoke" (non-smokers and women who quitted smoking during pregnancy)., Results: A percentage of 59.2 were non-smokers, 18.4% active smokers, 8.5% second-hand smokers and 13.8% had stopped smoking. Unexposed pregnant women who stopped smoking had the same risk of premature deliveries and children with similar birth weight as non-smoker women. Active and second-hand smokers were at higher risk of preterm deliveries than non-smokers (odds ratio [OR] 6.5, 95% confidence interval [95% CI] 1.4-30.8 and OR 6.2, 95% CI 1.0-38.9, respectively); however, higher levels of hemoglobin in the 1st and 3rd trimester exerted a protective effect (OR 0.9, 95% CI 0.8-0.9). Active and second-hand smokers had babies weighing less than non-smokers (around 129 and 178g less, respectively)., Conclusions: Active or passive exposure to smoke during pregnancy and lower hemoglobin levels are associated with an increased risk of premature deliveries and lower birth weight. Stopping smoking during pregnancy prevents these detrimental effects., (Copyright © 2013 Elsevier España, S.L. All rights reserved.)
