Dietary Patterns and Weight Status in Italian Preschoolers with Autism Spectrum Disorder and Typically Developing Children

Sensory sensitivity and intelligence are correlated with nutrient deficiency in children with autism spectrum disorder and intellectual disability

BACKGROUND/OBJECTIVES

Relationship between dietary intake and sensory sensitivity and intelligence in autism spectrum disorder (ASD) is not well described. This study aims to investigate nutrition status in children with ASD and ID and its association with sensory sensitivity and intelligence.

SUBJECTS/METHODS

84 students (34 ASD and 48 ID) in a special education school were recruited. Dietary intakes were evaluated with 3-day food dairy. Sensory sensitivity was measured using short sensory profile (SSP). Wechsler IQ test were performed.

RESULTS

Two out of twenty-four investigated nutrients had an adequate intake rate of over 50%. Four out of ten investigated vitamins had an inadequate intake rate of over 90% and another two over 80%. 75.6% of participants had inadequate energy intake. After adjusting for age, ASD participants had a higher intake of all surveyed nutrients but only the intake of vitamin E and folate were statistically different (p < 0.05) along with a smaller number of inadequate nutrients (p < 0.001). Taste/smell sensitivity, movement sensitivity, underresponsive/seeks sensation, and total sensory sensitivity symptoms severity were slightly higher in ASD group than in ID group (all p < 0.05). After adjusting for IQ and sensory sensitivity score, difference of number of inadequate nutrients between ASD and ID group were not statistically significant (p = 0.193).

CONCLUSIONS

Individuals with ASD had better dietary intake but worse sensory sensitivity compared to those with ID. Sensory sensitivity and intelligence are correlated with nutritional status in individuals with neurodevelopmental disorder.

Eating disorder in children: Impact on quality of life, with a spotlight on autism spectrum disorder

Eating behavior, which includes eating habits and preferences, frequency of eating, and other features related to diet, is a major characteristic not only of a person's nutritional status, but also of health in general. In recent years, the prevalence of eating disorders in children has tended to increase; they also require cross-system approaches in diagnosis by a variety of specialists and correction requires appropriate selection of optimal methods. Maladaptive eating attitudes formed at an early age can contribute to the formation of eating disorders, which can lead to or worsen various neuropsychiatric diseases, digestive diseases, and other related conditions. In children with autism spectrum disorder (ASD), eating disorders often appear earlier than other major symptoms of the condition. However, the clinical manifestations of eating disorders in children with ASD are varied and differ in severity and duration, whereas these disorders in neurotypical children might present as short-lived and may not lead to serious consequences. Nevertheless, cases of progressive eating disorders accompanied by a child presenting as under- or overweight and/or with macronutrient and micronutrient deficiencies cannot be excluded. Given the high prevalence of eating disorders in children, many researchers have highlighted the lack of a valid and universally accepted instruments to assess atypical eating behaviors in this population. Therefore, in this review, we wanted to highlight the problems and causes of eating disorders in children, and also to analyze the existing approaches to the validation of these problems, taking into account the existing behavioral features in children with ASD.

Programmes to manage food selectivity in individuals with autism spectrum disorder

Autism spectrum disorder (ASD) is a complex group of neurodevelopmental disorders characterised by impaired social communication and restricted interests/repetitive behaviours. In this regard, sensory processing difficulties and delayed oral motor skills often predispose individuals with ASD to food selectivity (FS). It is usually associated with repetitive eating patterns that can lead to multiple malnutrition conditions. The objective of this narrative review is to present an overview about the existing nutritional interventions aiming at promoting a healthy eating pattern and addressing food selectivity among individuals with ASD. Regarding the interventions targeting nutrition education, the majority of the analysed studies failed to demonstrate their effectiveness. On the other hand, many educational interventions involving taste or cooking sessions, as well as behavioural interventions for FS, demonstrated effective results. Moreover, multidisciplinary in tailoring such programmes, including psychology speech therapy and nutritional skills, is acknowledged as a key approach.

Brief Report: Plasma Leptin and Mealtime Feeding Behaviors Among Children with Autism Spectrum Disorder: A Pilot Study

We examined the relationship between weight status, appetite regulating hormones, and mealtime behaviors among children, (5-12 years old), diagnosed with Autism Spectrum Disorder (ASD) in a cross-sectional study. All (N = 21) completed anthropometry measurements and (n = 18) provided blood samples for hormone analysis. Mealtime behavior, dietary, physical activity, puberty stage, and social impairment data were collected. Under fasting conditions, overweight/obese (OWOB) participants, (n = 6), had higher leptin concentrations (p < 0.02) and more feeding challenges (p < 0.05) than normal weight (n = 15). Higher leptin levels and disruptions in mealtime behaviors may exist among OWOB children in this study. Future longitudinal studies that examine appetite regulating hormones and mealtime behaviors may inform our understanding of the role of these markers in the development of obesity in ASD.

The Role of Nutrition in Neurological Disorders

The interplay between nutrition and neurology has gained increasing recognition and various studies have emerged showing malnutrition and nutritional imbalances as a cause and result of certain neurological pathologies [...].

Dietary recommendations to customize canteen menus according to the nutritional and sensory needs of individuals with autism spectrum disorder

Individuals with autism spectrum disorders (ASD) are often characterized by food-selectivity, food-neophobia and a marked preference for mild flavor, semi-liquid foods with pale colors. Therefore, they adopt a monotonous dietary pattern, and they prefer ultra-processed food, leading to a high risk of developing malnutrition. In Italy, where 75,072 individuals are diagnosed with ASD, center-based services play a crucial role in their daily management. Despite the centrality of nutrition in maintaining a good state of health, even more for vulnerable subjects, no validated protocol at collective catering level has been developed yet. The manuscript presents customized dietary recommendations aimed at managing the meals for individuals with ASD at collective catering service, derived from a non-systematic literature review exploring food behaviors and nutritional needs in individuals with ASD. Simple practical tips for mealtimes, such as eating together, proper seating, lighting, smell control, presenting food in a simple manner and using the same type of tableware at each meal, to meet the needs of individuals with ASD, were described. The proposal could represent a starting point in developing official guidelines aimed at ASD individuals, in collective catering service.Level of Evidence: Level V.

Brief Autism Mealtime Behavior Inventory (BAMBI): Italian Translation and Validation

Food selectivity is among the most common problems for children with Autism Spectrum Disorder (ASD). The present study aims to validate the Brief Autism Mealtime Behavior Inventory (BAMBI) in an Italian population of children with ASD. BAMBI was translated and cross-culturally adapted following international guidelines, then we investigated internal consistency as measured by Cronbach's alpha and test-retest reliability, as measured by the Intraclass Correlation Coefficient (ICC) in a sample of both children with ASD and with typical development (TD). A total of 131 children were recruited in a clinical and community sample. Internal consistency revealed significant data for both TD and ASD children, with a Cronbach's Alpha of 0.86 and 0.71, respectively. Test-retest reliability showed excellent values for each item of the BAMBI (range 0.83-1.00). Furthermore, we investigated differences in gender and body max index; however, no significant differences were found among groups. In conclusion, the Italian version of the BAMBI showed good internal consistency and test-retest reliability and it can be used for clinical and research purposes.

Gastrointestinal Disorders and Food Selectivity: Relationship with Sleep and Challenging Behavior in Children with Autism Spectrum Disorder

The aim of this study was to evaluate the interaction between gastrointestinal (GI) disorders, sleep problems, and challenging behaviors in children with a diagnosis of Autism Spectrum Disorder (ASD) and their effect on parental stress. The secondary objective was to assess the frequency and type of GI and feeding disorders in a sample of children with ASD through a multidisciplinary assessment and, finally, to investigate families' perceptions and satisfaction with the proposed multidisciplinary approach. All children underwent a comprehensive gastroenterological and neuropsychiatric evaluation supported by standardized questionnaires. Pediatric gastroenterologists, specifically trained in Applied Behavior Analysis (ABA), provided advice for parent-delivered behavioral intervention for food selectivity. Thirty-six children with an autism diagnosis (29 males, age 4.5 +/-2.2 years, mean +/- SD) were enrolled. A positive correlation between sleep problems and aggressive behavior was found, and this association was stronger in children experiencing more problematic mealtime behaviors (b = 0.788, p = 0.014). Sleep difficulties were associated with stereotyped behaviors and parent-perceived stress. Parents interviewed about the gastroenterology visit perceived this multidisciplinary approach as helpful in addressing food selectivity. This study shows that sleep and mealtime issues can have a synergistic negative impact on ASD symptoms. A multidisciplinary approach and an integrated assessment of GI, feeding problems, and sleep disorders could be helpful in diagnosing comorbidities and to provide targeted advice to parents.

Assessment of Feeding Behaviors and Parents' Frustrations of Children with Autism Spectrum Disorder in Lebanon: A Case-Control Study

Children with autism spectrum disorder (ASD) exhibit restrictive and repetitive behaviors that affect their eating habits. The purpose of this study is to identify the behavioral feeding problems and eating habits among ASD children compared to typically developed (TD) children age/gender-matched controls, along with their parents'/caregivers' strategies for dealing with them. It included 43 ASD children and 43 TD children aged two to eleven years. The analysis was performed based on two valid questionnaires: the Behavior Pediatrics Feeding Assessment Scale (BPFA) and "My Child Eating Habits" (MCEH). The BPFA and MCEH scores conceded three manifestations that fall into food selectivity and problematic mealtime behavior in both groups of children. Compared to TD children, children with ASD exhibited higher BPFA scores, which indicated food-related behavioral and skill-based problems (p = 0.004). Children with ASD were less likely to consume fruits, vegetables, and milk than TD children, which may lead to nutritional deficiencies (p = 0.003, p = 0.003, and p = 0.010, respectively). Parents of ASD children were concerned about their behavioral problems and expressed their intention of an early intervention. These findings highlight the importance of nutritional clinical routines that incorporate the evaluation of the nutritional status and feeding behaviors of ASD children.

Insights on dental care management and prevention in children with autism spectrum disorder (ASD). What is new?

Autistic subjects represent a severe concern to dentistry due to the considerable difficulty in managing their oral health, maintaining routine toothbrushing, and preventing dental and periodontal problems. The social and economic burden of managing dental care in autism spectrum disorder (ASD) children is particularly cumbersome for families and public and private health expenditure, especially when children reach the dentist following a late diagnosis with evident oral health problems. An early diagnosis of ASD helps dentists better address these children's oral health. Unfortunately, insufficient attention is paid to the training and education of general pediatricians, dentists, and dental hygienists, allowing them to get to approach the different clinical aspects of ASD. Usually, children diagnosed with ASD are scheduled for dental appointments like their neurotypical peers, whereas their needs are typically complex and personalized. Scant attention is also devoted to these patients by commercial manufacturers of dental products and devices for oral hygiene and prevention of caries and periodontal diseases, leaving parents without the support and often failing when they address the oral health of autistic children. The difficulties of oral care do not derive simply from the behavior of ASD patients, as is commonly assumed, and therefore cannot be overcome solely by the patience and attention of parents and dentists. Genetics, dietary habits, sensory impairments, and cognition disorders are other causes contributing in various degrees to the impact on the mood and psychological reactions of autistic children towards dentists. How can we prevent teeth caries, periodontal disorders, and other oral health impairments by properly managing ASD children? This manuscript gives an up-to-date overview of these problems and helps to provide good remarks.

The association between sugar-sweetened beverages and milk intake with emotional and behavioral problems in children with autism spectrum disorder

Background

Emotional and behavioral problems are common in children with autism spectrum disorder (ASD). It's still unclear whether children with ASD have abnormal sugar-sweetened beverages (SSBs) and milk intake and whether this abnormality will affect their emotions and behavior remains unclear. The current study aims to investigate the association of SSBs and milk intake with emotional and behavioral problems in children with autism spectrum disorder (ASD).

Methods

107 children with ASD and 207 typical developing (TD) children aged 6-12 years old were recruited for the study. The frequency of SSBs and milk intake was assessed by a self-designed questionnaire. Emotional and behavioral problems were assessed by Strength and Difficulties Questionnaire (SDQ). Then, the linear regression model was produced to evaluate the association of SSBs and milk intake with emotional and behavioral problems.

Results

In the current study, there was no difference in frequency of SSBs intake between children with ASD and TD children (p > 0.05), and children with ASD consumed less milk compared to TD children (p < 0.05). After adjusting sex, age, maternal and paternal education, and monthly family income, we found a significant difference in each subscale score of SDQ in the two groups (p < 0.05). In children with ASD, higher frequent SSBs intake was positively associated with the scores of the emotional problem (p for trend <0.05), and lower frequent milk intake was inversely associated with the scores of prosocial behavior (p for trend <0.05). No interactive effects were found on SSBs and milk intake with emotional and behavioral problems (p for trend > 0.05).

Conclusion

In children with ASD, frequency of SSBs and milk intake was associated with the emotional problem and prosocial behavior, respectively. Children with ASD should increase the frequency of milk intake and decrease the frequency of SSBs intake.

Vitamin D Status in Children with Autism Spectrum Disorders: Determinants and Effects of the Response to Probiotic Supplementation

A relationship between the presence of clinical symptoms and gastrointestinal (GI) disturbances associated with nutritional deficiencies, including vitamin D (25(OH)D) deficiency, has been observed in autism spectrum disorder (ASD). The aim was to evaluate 25(OH)D levels according to the annual rhythm cycle, gender, the severity of autism, nutritional or clinical status, inflammatory and metabolic biomarkers, GI symptoms, and the clinical response to probiotic/placebo supplementation in preschooler children with ASD. Eighty-one ASD preschoolers (67 males) were assessed with standardized tools for ASD severity (ADOS score) and GI symptoms (by GI-Index at six-items and at nine-items, the latter defined as the Total GI-Index). The 25(OH)D levels were compared among different ASD subgroups according to metabolic and inflammatory biomarkers (leptin, insulin, resistin, PAI-1, MCP-1, TNF-alfa, and IL-6), gender, and the presence or absence of: (i) GI symptoms, (ii) the response to probiotic supplementation (the improvement of GI symptomatology), (iii) the response to probiotic supplementation (improvement of ASD severity). Only 25% of the ASD children presented an adequate 25(OH)D status (≥30 ng/mL according to the Endocrine Society guidelines). All the 25(OH)D levels falling in the severe deficiency range (<10 ng/mL) were observed in the male subgroup. A significant inverse correlation between 25(OH)D and leptin was observed (R = −0.24, p = 0.037). An inverse correlation was found between 25(OH)D levels and the GI Index 6-Items and Total GI-Index (R = −0.25, p = 0.026; −0.27, = 0.009) and a direct relationship with the probiotic response (R = 0.4, p = 0.05). The monitoring of 25(OH)D levels and the co-administration of 25(OH)D and probiotic supplementation could be considered in ASD from early ages.

Feeding and Swallowing Issues in Autism Spectrum Disorders

Children with autism spectrum disorder (ASD) often experience difficulties related to communication and behaviour. However, their feeding issues are most distressing to their families and healthcare professionals as they impact on the children's adaptive function and health. In comparison to typically developing children, those with ASD experience significantly more feeding difficulties. Children with ASD may display distinctive feeding difficulties and atypical feeding behaviours that include picky eating, limited independent feeding, need for increased feeding times, and a highly restrictive food repertoire. Many of these feeding difficulties continue into childhood, persist in adolescence, and even spill over into adulthood. This proves to be a formidable challenge, as feeding is an essential component for healthy nutrition, growth, and development. This article will highlight how particular food items that are eaten and preferred by affected children may be contributing to their exhibited feeding difficulties. Next, it will be shown how the children's restrictive diets supplant more healthy food options. When this is combined with the children's noted reduced physical activity, the consequences are especially serious, as they include not only malnutrition but also give rise to childhood obesity. In sum, it will be demonstrated that feeding difficulties in young children with ASD are not well understood nor managed. The dearth of knowledge about feeding issues in this population affects both assessment choices and, specifically, management practices - aspects that will be elaborated on in this article. Conclusions will include suggested future directions for enhancing and complementing knowledge of these issues for stakeholders.
