Association Between Breastfeeding Initiation and Duration and Autism Spectrum Disorder in Preschool Children Enrolled in the Study to Explore Early Development

Breastfeeding patterns in infants are associated with a later diagnosis of autism Spectrum disorder

Breastfeeding is associated with medical and developmental benefits. This study aimed to assess associations between nutritional patterns in the first year of life and the likelihood of autism spectrum disorder (ASD). 270 children diagnosed with ASD (cases) and 500 neurotypical children (controls) matched to cases by sex, ethnicity, and birth date (± 3 months) were included in this retrospective case-control study. Both groups were ascertained from children born between 2014 and 2017 whose development/nutrition were monitored at mother-child health clinics in southern Israel. Conditional logistic regression was used to determine the independent association of nutritional patterns with ASD while adjusting for socio-demographic and clinical characteristics. Both exclusive and partial breastfeeding modes were associated with decreased odds of ASD diagnosis (aOR = 0.221, 95%CI = 0.136-0.360; aOR = 0.494, 95%CI = 0.328-0.743, respectively). A breastfeeding duration of >12 months was associated with lower ASD odds (aOR = 0.418, 95%CI = 0.204-0.855), while the introduction of solids after 6 months of age was associated with higher ASD odds than the introduction of solids at 6 months (aOR = 2.455, 95%CI = 1.116-4.201). These findings suggest that a longer period of exclusive breastfeeding is associated with a subsequent reduced likelihood of ASD diagnosis, thus reiterating the importance of proper post-natal nutrition for infant neurodevelopment.

Gastrointestinal Symptoms in Autism Spectrum Disorder: A Case-Control Study

Background and objectives This study aimed to explore the frequency of gastrointestinal (GI) symptoms and associated risk factors among children with autism spectrum disorder (ASD). Methods This was a retrospective case-control study including children aged 2-14 years diagnosed with ASD by the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 criteria and the assessment card in the ASD center at King Salman Armed Forces Hospital. Data were obtained using a self-developed questionnaire that included demographic features, nutritional and behavioral characteristics, and GI symptoms in the previous six months. The control group consisted of typically developing (TD) children matched to the ASD group for age and gender. Syndromic autism with defined somatic abnormalities and recognized genetic causes (e.g., fragile X syndrome, tuberous sclerosis) were excluded Results A total of 146 ASD children and 114 normal children were included. No significant demographic differences were found between the groups. The ASD group had a higher frequency of low income and a significantly lower rate of exclusive breastfeeding in the first six months. GI symptoms, specifically constipation, abdominal gases and distension, diarrhea, undigested food particles in stool, and mouth ulcers, were significantly more frequent in the ASD group. Weight abnormalities (both increase and decrease) were also more common. Family history of ASD was significantly more in ASD children with GI symptoms while low maternal education was more in those without. Conclusion This study reveals a high prevalence of GI symptoms in ASD children. Family history of ASD and maternal education may influence the GI symptoms reported in ASD children.

Association of Breastfeeding Duration with Neurodevelopmental Outcomes in an Enriched Familial Likelihood Cohort for Autism Spectrum Disorder

This study aimed to compare the breastfeeding (BF) duration of the younger siblings of children with ASD in an enriched-likelihood cohort for autism spectrum disorder (ASD), and to determine whether longer BF duration was associated with differences in neurodevelopmental outcomes in this cohort. Information on BF practices was collected via surveys in the MARBLES (Markers of Autism Risk in Babies-Learning Early Signs) study. Developmental evaluations, including the Mullen Scales of Early Learning and the Autism Diagnostic Observation Schedule, were conducted by expert clinicians. Participants' neurodevelopmental outcome was classified by an algorithm into three groups: typical development, ASD, and non-typical development. The median duration of BF was 10.70 months (interquartile range of 12.07 months). There were no significant differences in the distribution of duration of BF among the three neurodevelopmental outcome categories. Children in this enriched-likelihood cohort who were breastfed for > 12 months had significantly higher scores on cognitive testing compared to those who were breastfed for 0-3 months. There was no significant difference in ASD symptomatology or ASD risk based on BF duration.

Socio-economic status and autism spectrum disorder: A case-control study in Bangladesh

There are unexpectedly a few statistics about the socio-economic status (SES) and related socio-demographic factors (SDFs) of parents having child with ASD in Bangladesh. The prevalence of ASD might correlate with SES and related SDFs. A case-control study was conducted in 24 locations across 21 districts, encompassing all divisions, to assess the association between SES and the risk of developing ASD in Bangladesh. The structured questionnaire was administered through face-to-face interviews with 620 parents of the subject (310 ASD and 310 healthy controls) from January 2020 to June 2021. For univariate, bivariate and multivariate analyses, IBM SPSS version 23 was employed. The significance level was set at P ≤ 0.05, and the Odds Ratio (OR) within a 95 % CI was used to determine whether the variable poses a higher odd or not. After adjusting all significant covariates of binary logistic regression (including some dummy variables) in forward logistic regression model analysis, the higher level of SES, advanced level of father's education (≥master), 22-35 years old age group of the father, and nuclear family were strongly associated with decreased odds of ASD compared to healthy controls. Only the male gender was strongly associated with an increased odds of ASD compared to the control. The results will aid policymakers in developing plans considering the SES and related SDFs that influence the risk of developing ASD in Bangladesh. Further research using population-based cohorts or nested case-control designs with matched control is necessary to observe and generalize the association.

Infant feeding practices and autism spectrum disorder in US children aged 2-5 years: the national survey of children's health (NSCH) 2016-2020

OBJECTIVE

To investigate the relationship between infant feeding practices and autism spectrum disorder (ASD) among children aged 2-5 years in the United States (US).

METHODS

Data from the 2016-2020 National Survey of Children's Health, a nationally representative cross-sectional survey, were utilized for this study. Questionnaires were administered to parents of children aged 2-5 years to gather information on ASD diagnosis, infant feeding practices, and demographic factors (e.g., child sex, ethnic group, and maternal age at birth). Logistic regression with sample weights was employed to assess the association between infant feeding practices and ASD, while controlling for demographic variables. Polynomial regression models were used to examine trends in exclusive breastfeeding and ever breastfeeding rates among children with and without ASD.

RESULTS

A total of 35,050 children aged 2-5 years were analyzed, including 616 diagnosed with ASD, after excluding participants with missing information on breastfeeding and ASD diagnosis. Of these children with ASD, 76.6% (n = 472) had a breastfeeding history, with 67.5% (n = 416) engaged in partial breastfeeding and 9.1% (n = 56) exclusively breastfed. Adjusted odds ratios for each additional month of breastfeeding compared to never being breastfed were 0.98 (95% CI, 0.96-1.01). The adjusted odds ratios for breastfeeding durations of > 0-6 months, > 6-12 months, > 12-24 months, and > 24 months were 0.81 (95% CI, 0.50-1.31), 0.65 (95% CI, 0.36-1.18), 0.81 (95% CI, 0.44-1.49), and 0.48 (95% CI, 0.23-1.01), respectively. Compared to children who were never breastfed, the adjusted odds ratio for children who were ever breastfed was 0.74 (95% CI, 0.47-1.18). Among children with ASD, the proportion of ever breastfeeding declined from 82.0% in 2017 to 64.3% in 2020, while exclusive breastfeeding decreased from 12.0% in 2016 to 4.2% in 2020.

CONCLUSIONS AND RELEVANCE

Although no significant association was found between infant feeding practices and ASD among US children aged 2-5 years, the rates of breastfeeding, particularly exclusive breastfeeding, were suboptimal among children with ASD. This highlights the need for specific policies and practices to promote and support breastfeeding among parents of children with ASD or those at high risk of having a child with ASD.

Breastfeeding is not a risk factor for clinical severity in Autism spectrum disorder in children from the ELENA cohort

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that results from a complex interaction between genes and environment. Breastfeeding (BF) is thought to promote healthy cognitive development, and a body of research has suggested that it may also protect against ASD. Our objectives were to identify the relationship between the initiation and duration of BF and the severity of clinical presentation in ASD. Data were collected from 243 children with a confirmed diagnosis of ASD followed in the ELENA cohort. Clinical severity was measured according to multiple dimensions using standardised tools. The frequency of the initiation of BF was comparable to that of the general population and the rate of children still being breastfed at six months of age was higher. Our results did not indicate a contribution of initiation or duration of BF to the prevention of clinical severity of ASD. We discuss our results in the light of possible methodological limitations of previous reports of an association between BF and ASD.Clinical Trial Registration: NCT02625116.

Not breastfeeding and risk of autism spectrum disorders among children: a meta-analysis

BACKGROUND

To our knowledge, this is the first meta-analysis of the association of not breastfeeding and the risk of autism spectrum disorder (ASD) based on observational studies.

PURPOSE

This meta-analysis aimed to evaluate of the association of not breastfeeding and the risk of ASD.

METHODS

Three databases (PubMed, Web of Science, and Scopus) were systematically searched until December 2021. Heterogeneity was determined using the chi-square test and its quantity was measured using the I2 statistic. The Begg line regression test was used to assess publication bias. A random-effects model was used to analyze the data. Seven studies were included in this meta-analysis.

RESULTS

The total study population included 3,270 individuals. According to the random-effects model, the estimated odds ratio of the risk of ASD associated with not breastfeeding was 1.81 (95% confidence interval, 1.35-2.27; I2=0%).

CONCLUSION

The results of the included studies were homogeneous. Our findings showed that not breastfeeding is a risk factor for ASD. These results suggest the importance of breastfeeding in decreasing the risk of ASD in children.

The function of gut microbiota in immune-related neurological disorders: a review

This review provides an overview of the importance of microbiota in the regulation of gut–brain communication in immune-related neurological disorders. The gastrointestinal (GI) tract hosts a diverse abundance of microbiota, referred to as gut microbiota. The gut microbiota plays a role in the maintenance of GI tract homeostasis and is likely to have multiple effects on brain development and function. The bidirectional communication between the gut microbiota and the brain is termed the microbiota–gut–brain axis. This communication between the intestine and the brain appears to affect human health and behavior, as certain animal studies have demonstrated the association between alterations in the gut microbiota and neurological disorders. Most insights about the microbiota–gut–brain axis come from germ-free animal models, which reveal the importance of gut microbiota in neural function. To date, many studies have observed the impact of the gut microbiota in patients with neurological disorders. Although many studies have investigated the microbiota–gut–brain axis, there are still limitations in translating this research to humans given the complexities of the relationship between the gut microbiota and the brain. In this review, we discuss emerging evidence of how the microbiota–gut–brain axis regulates brain development and function through biological networks, as well as the possible contribution of the microbiota–gut–brain axis in immune-related neurological disorders.

Association of Breastfeeding for the First Six Months of Life and Autism Spectrum Disorders: A National Multi-Center Study in China

Previous studies have shown that exclusive breastfeeding is associated with lower odds of having autism spectrum disorders (ASD) in children, but data are lacking in Asian countries, especially China. This cross-sectional study of seven cities in China collected data from August 2016 to March 2017 from 6049 toddlers aged 16-30 months and their parents who responded to questionnaires. The breastfeeding status was collected via questionnaires based on recommendations from the World Health Organization. The standard procedure for screening and diagnosis was applied to identify toddlers with ASD. Among the 6049 toddlers (3364 boys [55.6%]; mean [SD] age, 22.7 [4.1] months), 71 toddlers (1.2%) were identified as ASD. The prevalence of exclusive breastfeeding, partial breastfeeding, and not breastfeeding was 48.8%, 42.2%, and 9.1%, respectively. Compared to toddlers with exclusive breastfeeding, toddlers with partial breastfeeding or without breastfeeding had higher odds of having ASD (odd ratios [OR]: 1.55, 95% confidence interval [CI]: 0.90-2.74; OR: 2.34, 95% CI: 1.10-4.82). We did not find significant modification of demographic characteristics on the associations. The results remained robust in multiple sensitivity analyses. Toddlers without breastfeeding for the first six months of life had higher odds of having ASD, and our findings shed light on the necessity of strengthening public health efforts to increase exclusive breastfeeding in China.

Breastfeeding Experiences of Autistic Women

PURPOSE

The purpose of this study was to explore the experiences of autistic women who breastfed.

STUDY DESIGN AND METHODS

We used a qualitative phenomenology design and a thematic analysis method. Semistructured interviews were conducted using a purposive sample from social media support groups for autistic adults. The interview involved one overarching question about their breastfeeding experience.

RESULTS

Twenty-three autistic women who breastfed their infant(s) participated in our study. Three main themes were identified including intense sensory perception, focused determination, and one size doesn't fit all. Three subthemes helped to describe intense sensory perception: overstimulated, overtouched, and overwhelmed.

CLINICAL IMPLICATIONS

Autistic adults can have social interaction and expressive communication differences. Nurses can promote positive communication and provide appropriate care through supportive action. These findings offer a guide for nurses to better understand the experiences of autistic breastfeeding women.

Breastmilk Feeding during the First 4 to 6 Months of Age and Childhood Disease Burden until 10 Years of Age

BACKGROUND

Breastfeeding is recommended due to its beneficial effects on human health. However, the effect of breastfeeding on health differs, resulting in various childhood diseases.

OBJECTIVE

Our purpose was to investigate the association between breastfeeding at least in the first 4 months and the subsequent development of 15 certainly defined childhood diseases until 10 years of age, the all-cause hospitalization rate and growth at 6-7 years of age.

METHODS

Participants included propensity-score matched 188,052 children born between January 2008 and December 2009, who were followed up till 10 years of age. Data were taken from the National Investigation of birth Cohort in Korea study 2008 database. Risk ratios were obtained using a modified Poisson regression and weighted risk differences using binomial regression.

RESULTS

Compared to formula feeding, breastfeeding was associated with decreased risks of febrile convulsion, attention deficit hyperactivity disorder and autism spectrum disorder, pneumonia, acute bronchiolitis, hypertrophic pyloric stenosis, asthma, all-cause hospitalization, overweight/obesity and short stature. Exclusive breastfeeding at 4 to 6 months of age had similar results to exclusive breastfeeding over 6 months of age.

CONCLUSIONS

Breastfeeding in early infancy reduces the risk for various childhood diseases, all-cause hospitalization rate, obesity, and short stature during childhood.

Early Social Experience and Digital-Media Exposure in Children with Autism Spectrum Disorder

OBJECTIVE

To study the early social experience and digital media exposure in children with autism spectrum disorder (ASD) in comparison with typically developed children.

METHODS

Details of digital-media exposure and early social experience in 65 children with ASD were compared with those in a control group of equal number of typically developed children, matched for age and gender. Prenatal and perinatal factors were also studied. The diagnosis of ASD was based on the International Clinical Epidemiology Network (INCLEN) diagnostic tool and Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) diagnostic criteria. Variables which were biologically relevant and has a P value of < 0.05 in the univariate analysis were analyzed by logistic regression to obtain the adjusted effect measures.

RESULTS

Children with ASD were exposed to digital media at an earlier age and spent significantly more time with digital media and less time with their mothers, compared to typically developed children. Exposure to digital media before 21 mo was associated with risk of ASD and the risk increased when mothers spent less than 6.5 h per day with the baby. Family history of epilepsy and developmental delay, maternal stress during the antenatal period, and absence of exclusive breastfeeding during the first 6 mo were significantly more in children with ASD.

CONCLUSION

There are significant differences in the early life social experience and digital-media exposure in children with ASD compared to typically developed counterparts. Given the reported rise in prevalence of ASD, these findings stress the need for further prospective studies to explore these potentially modifiable risk factors.

Evaluation of Appetite-Regulating Hormones ın Young Children with Autism Spectrum Disorder

This study aimed to investigate the role of leptin, ghrelin, neuropeptide Y, and nesfatin-1 in young children with autism spectrum disorder (ASD). A total of 44 children with ASD and 44 healthy controls aged 18-60 months were included. Plasma levels of hormones were measured using commercial enzyme-linked immunosorbent assay kits. Plasma leptin and ghrelin levels were significantly higher in the ASD group than in the control group. However, no significant difference for plasma neuropeptide Y and nesfatin-1 levels was detected between the groups. No relation was found between the severity of ASD symptoms, severity of eating problems, and plasma levels of hormones. Leptin and ghrelin may play a potential role in the pathogenesis of ASD.

Associations between Prenatal Education, Breastfeeding and Autistic-Like Behaviors in Pre-Schoolers

This study aimed to investigate the association between prenatal education and autistic-like behaviors of preschoolers as well as the mediating role of breastfeeding in their associations. A cross-sectional study via a structured questionnaire was conducted with 67,578 preschool children and parents from Longhua District of Shenzhen, China. Hierarchical logistic regression models were performed to explore the associations between maternal participation in prenatal education and autistic-like behaviors in preschoolers, as well as the mediating effect of breastfeeding in the associations. After controlling for potential confounders, logistic regression analysis indicated that maternal participation in prenatal education could significantly increase the prevalence of breastfeeding, and the strength of the association was enhanced with the increase frequency of prenatal education visits (ORs ranging from 1.191 to 1.899). While both maternal participation in prenatal education (ORs ranging from 0.732 to 0.798) and breastfeeding (OR = 0.773) were significantly associated with the lower presence of autistic-like behaviors in preschoolers. The crossover analysis indicated that children with both maternal prenatal education and breastfeeding had the lower risk of presence of autistics-like behaviors (OR = 0.569). Furthermore, mediation analysis illustrated that breastfeeding mediated the association between maternal participation in prenatal education and the presence of autistic-like behaviors in preschoolers, with a mediating effect of approximately 14.3%. Our findings suggest that maternal participation in prenatal education is significantly associated with a decreased risk of autistic-like behaviors in preschool children through increased breastfeeding in the mothers who attended prenatal education.

Gut microbiota metabolites in autistic children: An epigenetic perspective

Gut microbiota has become an issue of great importance recently due to its major role in autism spectrum disorder (ASD). Over the past three decades, there has been a sustained research activity focused to explain the actual mechanism by which gut microbiota triggers/develops autism. Several genetic and epigenetic factors are involved in this disorder, with epigenetics being the most active area of research. Although the constant investigation and advancements, epigenetic implications in ASD still need a deeper functional/causal analysis. In this review, we describe the major gut microbiota metabolites and how they induce epigenetic changes in ASD along with interactions through the gut-brain axis.

Nursing personality and features in children with autism spectrum disorder aged 0-2: an exploratory case-control study

AIM

Although studies have investigated relationships between autism spectrum disorder (ASD) and breastfeeding duration, information concerning these children's nursing styles is limited. This study investigated nursing personality and features and ASD.

METHOD

One hundred forty-one children aged 24-72 months diagnosed with ASD and 128 healthy children were included. Information concerning the family's sociodemographic characteristics and the child's developmental stages was obtained through forms prepared by the authors and from hospital records. The Childhood Autism Rating Scale (CARS) was used to determine symptom severity in ASD. Development levels of children with ASD were determined using the Denver Developmental Screening Test 2nd Edition (DDST II).

RESULTS

Mothers of children with ASD reported higher rates of unintended pregnancies (p = 0.029) [2.380*(1.093-5.182)]. Children with ASD exhibited less nursing strike (NS) behavior (p = 0.042) [0.388(0.156-0.967)] and less eye contact during breastfeeding (ECDB) (p = 0.009) [2.300(1.236-4.282)]. NS reduced the risk of ASD 2.6-fold, while absence of ECDB increased the risk 2.3-fold, and unintended pregnancy increased the risk 2.4-fold. Higher CARS scores were determined in children with ASD with vaginal delivery histories (p = 0.041) and histories of incubation (p = 0.025). Lack of ECDB was associated with decreased social and gross motor scores at DDST-II (p = 0.005).

CONCLUSION

Babies with ASD began breastfeeding at least as early as typically developing peers and for similar lengths of time. However, babies with ASD exhibited less NS behavior and less eye contact during breastfeeding. Babies with ASD perceive no emotional cues even in the first months, and may therefore not exhibit NS behavior.

Do early-life eating habits predict later autistic traits? Results from a population-based study

Eating problems are common among children with Autism Spectrum Disorder (ASD), but it is unknown to what extent infant eating behavior is associated with later autistic traits. As eating behavior is currently not included in ASD screening instruments, it is important to evaluate whether infant eating behavior predicts later autistic traits and might therefore be used to enhance the early detection of ASD. We investigated the association of breastfeeding and eating behavior during infancy with later autistic traits in the population-based Generation R cohort. We included 3546 mother-child dyads with maternal reports on feeding and eating at age two months and autistic traits at six years. Eating behavior was assessed with seven items on specific eating habits and the Social Responsiveness Scale was used to evaluate autistic traits. Covariates included child sex, and maternal psychopathology and autistic traits. Linear regression analyses showed that being formula fed at two months was associated with a higher autistic trait score at six years (adjusted B = 0.07; 95% CI: 0.00-0.14). Children who were drinking only small quantities (adjusted B = 0.17, 95% CI: 0.04-0.30) and were hungry/not satisfied (adjusted B = 0.23, 95% CI: 0.08-0.39) at age two months also had a higher autistic traits score at age six years. We found no interactions with sex or breastfeeding. This study shows that eating behavior during infancy is related with autistic traits in childhood. Although the associations were fairly small, these findings suggest that early-life eating problems might be relevant for early detection of ASD and a potential addition to ASD-specific screening instruments.

Eating and Mealtime Behaviors in Patients with Autism Spectrum Disorder: Current Perspectives

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impaired social and communication skills and repetitive and restrictive behaviors. Children and adolescents with ASD are more likely to present feeding problems than their typically developing peers are. The present narrative review of literature aims to highlight the most recent evidence about epidemiology and presentations of eating and mealtime behavioral abnormalities in ASD from infancy to adolescence. Abnormalities in breastfeeding and acceptance of complementary foods have been described by most of the studies evaluating ASD early feeding history. Among the various eating and mealtime behaviors identified in ASD children and adolescents, the most common was food selectivity. The present review also provides brief overviews of the various aspects of food that may influence food acceptance by ASD patients and of the correlation between eating problems and ASD core symptoms, as well as with cognitive level, language skills, and family environment. However, studies evaluating eating problems in ASD children and adolescents are very heterogeneous and they show methodological differences. Moreover, the absence of unique definitions of eating and mealtime behaviors in ASD further limits the comparability of studies.

Modeled prenatal exposure to per- and polyfluoroalkyl substances in association with child autism spectrum disorder: A case-control study

BACKGROUND/OBJECTIVE

Per- and polyfluoroalkyl substances (PFAS) display neurobehavioral toxicity in laboratory animal studies. We examined associations of modeled prenatal maternal exposure to PFAS with child diagnosis of autism spectrum disorder (ASD).

METHODS

Participants were 453 mother-child pairs from CHARGE (CHildhood Autism Risk from Genetics and Environment), a population-based case-control study. Children underwent psychometric testing and were clinically confirmed for ASD (n = 239) or typical development (TD, n = 214). At the end of the clinic visit, maternal blood specimens were collected. We quantified nine PFAS in maternal serum samples collected when their child was 2-5 years old. As surrogate in utero exposure, we used a model built from external prospective data in pregnancy and 24 months post-partum and then reconstructed maternal PFAS serum concentrations during pregnancy in this case-control sample. We used logistic regression to evaluate associations of modeled prenatal maternal PFAS concentrations with child ASD.

RESULTS

Modeled prenatal maternal perfluorohexane sulfonate (PFHxS) and perfluorooctane sulfonate (PFOS) were borderline associated with increased odds of child diagnosis of ASD (per nanogram per milliliter increase: odds ratio [OR] = 1.46; 95% confidence interval [CI]: 0.98, 2.18 for PFHxS, OR = 1.03; 95% CI: 0.99, 1.08 for PFOS). When compared to the lowest quartile (reference category), the highest quartile of modeled prenatal maternal PFHxS was associated with increased odds of child diagnosis of ASD (OR = 1.95; 95% CI: 1.02, 3.72).

CONCLUSIONS

In analyses where modeled prenatal maternal PFAS serum concentrations served as in utero exposure, we observed that prenatal PFHxS and PFOS exposure, but not other PFAS, were borderline associated with increased odds of child diagnosis of ASD. Further studies in which PFAS concentrations are prospectively measured in mothers and children at a range of developmental stages are needed to confirm these findings.

The putative etiology and prevention of autism

Since the initial psychological report by Leo Kanner in 1943, relatively little formal biochemical/neurological research on the cause of autism, other than peripheral searches for genomic mutations, had been carried until the end of the 20th century. As a result of studies on twin sets and the conclusion that autism was largely a hereditary defect, numerous investigations have sought various genetic faults in particular. However, such studies were able to reveal a plausible etiology for this malady in only a small percentage of instances. Key bio-molecular characteristics of this syndrome have been uncovered when the potential roles of the glia were studied in depth. Findings related to biochemical deficiencies appearing early in the newborn, such as depressed IGF-1 (insulin-like growth factor #1) in neurogenesis/myelination, are becoming emphasized in many laboratories. Progress leading to timely diagnoses and subsequent prevention of central nervous system dysconnectivity now seems plausible. The tendency for an infant to develop autism may currently be determinable and preventable before irreversible psychosocial disturbances become established. These discussions about glial function will be inter-spersed with comments about their apparent relevance to autism. The concluding portion of this presentation will be a detailed review and summation of this diagnosis and prevention proposition.

The role of oligopeptides in preventing autism

Previous reports in this series point to insufficient insulin-like growth factor-1 (IGF1) in the newborn as the key to brain dysconnectivity characteristic of autism. Such a deficiency should be detectable in the baby's blood at or soon after birth. Breast-feeding exclusively for the first year of postpartum life or supplementation with oral agents to raise the serum IGF1 level, such a cyclo-glycylproline, could be helpful for this purpose.

The association between maternal features and nutritional problems in children with autism spectrum disorder

ABSTRACT Objective In the literature, there is almost no data on the relationship between autistic children’s nutritional problems and their mothers’ demographic and nutritional characteristics. Therefore, this study aimed to evaluate whether there was a relationship between maternal features and nutritional problems in autistic children. Methods This study was conducted with the participation of 58 autistic children (6-19 years) and their mothers. Descriptive data were obtained with a general questionnaire. For the evaluation of children’s nutritional status, anthropometric measurements and 24-hour dietary recall were used. Also, the Brief Autism Mealtime Behavior Inventory and ORTO-15 questionnaires were used to evaluate the meal behavior of children and orthorexia tendency of mothers, respectively. Results No significant correlation was found between the Brief Autism Mealtime Behavior Inventory scores in children of mothers with high and low orthorexia tendency. There were also no statistically significant differences between the children of mothers with high and low educational level in terms of Brief Autism Mealtime Behavior Inventory scores. Only the dietary vitamin B6 intake was significantly higher in the children of mothers with high educational level. Maternal age was associated with the dietary energy and protein intake, unlike, maternal orthorexia tendency was not associated with the nutritional status and meal behavior of children. The abdominal pain experience in the last one month was found to be significantly higher in the children of employed mothers than children of unemployed mothers. Conclusion It is thought that the maternal characteristics are not effective on meal behavior in children and also maternal age and educational status have a very limited effect on the nutritional status of children.
