Feeding and swallowing difficulties in children with Down syndrome

Trisomy 21 and Congenital Heart Disease: Impact on Health and Functional Outcomes From Birth Through Adolescence: A Scientific Statement From the American Heart Association

Due to improvements in recognition and management of their multisystem disease, the long-term survival of infants, children, and adolescents with trisomy 21 and congenital heart disease now matches children with congenital heart disease and no genetic condition in many scenarios. Although this improved survival is a triumph, individuals with trisomy 21 and congenital heart disease have unique and complex care needs in the domains of physical, developmental, and psychosocial health, which affect functional status and quality of life. Pulmonary hypertension and single ventricle heart disease are 2 known cardiovascular conditions that reduce life expectancy in individuals with trisomy 21. Multisystem involvement with respiratory, endocrine, gastrointestinal, hematological, neurological, and sensory systems can interact with cardiovascular health concerns to amplify adverse effects. Neurodevelopmental, psychological, and functional challenges can also affect quality of life. A highly coordinated interdisciplinary care team model, or medical home, can help address these complex and interactive conditions from infancy through the transition to adult care settings. The purpose of this Scientific Statement is to identify ongoing cardiovascular and multisystem, developmental, and psychosocial health concerns for children with trisomy 21 and congenital heart disease from birth through adolescence and to provide a framework for monitoring and management to optimize quality of life and functional status.

Feeding practices and dietary intake in Brazilian children with Down syndrome: A cross-sectional study

BACKGROUND

Studies investigating the quality of the diet and dietary intake of children with Down syndrome (DS) are required because the features attributed to the syndrome can affect growth, development and quality of life.

METHODS

This cross-sectional study was conducted with 77 Brazilian children with DS between 5 and 36 months of age receiving care at the multidisciplinary outpatient clinic of the University Hospital. Participants' sociodemographic, dietary and anthropometric data were collected from the care protocols. Dietary data were collected from 24-h recalls and dietary practices were assessed according to the WHO dietary guidelines. Associations between inadequate feeding practices and demographic variables were assessed using logistic regression models.

RESULTS

Fruits, milk or infant formula, vegetables, beans and meat were among the five most consumed foods by the children investigated. Overall, we observed a high number of cases of early weaning (50.6%), low minimum dietary diversity (MDD; 40.3%), inadequate consistency for age (64.9%), early presence of ultra-processed foods (76.6%), sugars and sweets (33.8%) in the diet of the children with DS. In the associations of inadequate feeding practices by age group, low MDD [odds ratio (OR): 18.6; 95% confidence interval (CI): 3.4; 57.1] and inadequate consistency (OR: 6.65; 95% CI: 1.8; 24.7) were more frequent among children aged below 12 months while this relationship was inverse for early introduction of sugar and sweets (OR: 0.04; 95% CI: 0.01; 0.29).

CONCLUSION

Our findings showed a high number of cases of inadequate dietary practices in children with DS investigated, which could adversely affect the long-term health of this population.

Assessment and Rehabilitation Intervention of Feeding and Swallowing Skills in Children with Down Syndrome Using the Global Intensive Feeding Therapy (GIFT)

BACKGROUND

Children with Down syndrome (DS) experience more difficulties with oral motor skills, including chewing, drinking, and swallowing. The present study attempts to measure the preliminary effectiveness of Global Intensive Feeding Therapy (GIFT) in DS. GIFT is a new rehabilitation program addressing the specific difficulties and needs of each child, focusing on sensory and motor oral abilities. It follows an intensive schedule comprising 15 sessions over 5 consecutive days, with 3 sessions per day. The principles of GIFT are applied with specific objectives for DS.

METHODS

GIFT was preliminarily implemented among 20 children diagnosed with DS. To measure the efficacy of GIFT, the Karaduman Chewing Performance Scale (KCPS), the International Dysphagia Diet Standardization Initiative (IDDSI), and the Pediatric Screening-Priority Evaluation Dysphagia (PS-PED) were used. Data were analyzed using the Wilcoxon signed-rank test before (T0) and after intervention (T1) and at one-month follow-up (T2). The effect size was also measured for specific outcomes, using Kendall's W.

RESULTS

Our findings revealed that children with DS showed no risk of dysphagia according to the PS-PED (mean score 2.80). Furthermore, statistically significant improvements in chewing performance were observed, as measured by the KCPS (p < 0.01), as well as in texture acceptance and modification, as measured by the IDDSI post-intervention (p < 0.01). For both the KCPS and IDDSI, a large effect size was found (Kendall's W value > 0.8). Parents/caregivers continued using GIFT at home, and this allowed for a positive outcome at the one-month follow-up.

CONCLUSIONS

GIFT proved to be effective in the rehabilitation of feeding and swallowing disorders in children with DS, as well as for food acceptance.

Factors influencing gastrostomy tube feeding duration and nutrition outcomes in pediatric patients with Down syndrome: A descriptive cohort study

BACKGROUND

Feeding difficulty is widely recognized in patients with Down syndrome, and many patients require gastrostomy tube (G-tube) placement for nutrition. No reliable factors have been identified to predict the expected duration of G-tube feeds in patients with Down syndrome. This descriptive cohort study aimed to determine the factors affecting the duration of G-tube feeds. We also investigated change in body mass index (BMI) from G-tube placement to discontinuation.

METHODS

Medical records of patients with Down syndrome seen by a pediatric gastroenterologist at a tertiary care center between September 1986 and December 2021 were reviewed. Data collection included demographics, anthropometrics, comorbidities, and feeding route. Comparison was performed between patients who discontinued G-tube feeds and those who did not.

RESULTS

Two hundred twenty patients (45% female) were included. The median age at G-tube placement was 5 months (interquartile range [IQR]: 0.2-1.3 years). There were 113 (51%) patients who discontinued G-tube feeds, after a median duration of 31.6 months (IQR: 15.6-55.7 months). Tracheostomy was the only covariant associated with a longer duration of G-tube feeds (158 months vs 53 months; P = 0.002). Neither age at G-tube placement nor any comorbidities were associated with BMI status at discontinuation of G-tube.

CONCLUSION

In our cohort of patients with Down syndrome, age at placement of G-tube did not impact the duration of G-tube feeds. Most patients who had a G-tube placed were likely to require enteral feeds for at least 1 year. Those who had a tracheostomy needed their G-tube for a longer time.

Feeding therapy in a neurotypical child with feeding difficulties: A case report

A feeding therapy developed in Brazil integrates aspects from diverse approaches and has increasingly been acknowledged as an adjunctive approach for addressing childhood feeding difficulties. In children, problems with eating are a common issue that affects their nutritional well-being, health, and overall quality of life, and can greatly hinder their social, emotional, and physical growth. In the realm of pediatrics, feeding therapy uses food and nutritional education, interactive games, and activities tailored to age groups and individualized treatment plans. The primary objective is to transform mealtime experiences and gradually foster children's acceptance of previously rejected foods. However, this treatment approach is new and recent in Brazil and lacks studies that explore and elucidate the topic. Therefore, this report aims to describe the follow-up and effects of feeding therapy in a 3-y and 8-mo-old neurotypical male patient with feeding difficulties who underwent feeding therapy conducted by a dietitian over a period of 19 wk. The feeding therapy consisted of 45-min sessions once a week in which food and nutrition education activities, games, and interactive activities, personalized according to the treatment plan, were carried out. The effects of feeding therapy were evaluated according to the patient's feeding progression throughout the sessions and their stepwise progress in the eating hierarchy. Based on our observations, the findings of this study suggest that feeding therapy practiced in Brazil can be a viable treatment approach for addressing feeding difficulties within this population. The feeding therapy originated in Brazil stands out from traditional nutritional care with its nurturing and compassionate approach that prioritizes respect for the child.

Recurrent Respiratory Infections in Children with Down Syndrome: A Review

Down Syndrome (DS) is the most common chromosomal abnormality compatible with life. The life of patients suffering from DS can be strongly impacted by Recurrent Respiratory tract Infections (RRIs), leading to an increased rate of hospitalisation, a higher need for intensive care and fatality. With a literature review, we summarise here the main etiological factors for RRI in this category of patients, particularly focusing on airway malformations such as tracheomalacia, tracheal bronchus and bronchomalacia, comorbidities associated with the syndrome, like congenital heart diseases, dysphagia, gastroesophageal reflux, musculoskeletal involvement and obesity, and immunologic impairments, involving both innate and adaptive immunity. For these patients, a multidisciplinary approach is imperative as well as some preventive strategies, in particular vaccinations in accordance with their national schedule for immunization.

The influence of food sensory properties on eating behaviours in children with Down syndrome

Developing new food products for children is challenging, particularly in vulnerable groups including children with Down syndrome (DS). Focusing on children with DS, the aim of this study was to study the influence of parent liking on acceptance of food products by children with DS and demonstrate the influence of food sensory properties on indicators of food acceptance, food rejection, and challenging eating behaviours. Children (ages 1158 months) with DS (n = 111) participated in a home use test evaluating snack products with varying sensory properties as profiled by a trained sensory panel. Parents recorded their children's reactions to each food product; trained coders coded videos for eating behaviours. To understand the influence of each sensory modality on eating behaviour, ordered probit regression models were run. Results found a significant correlation between the parent liking and overall child disposition to the food (p < 0.05). From the regression analysis, the inclusion of all food sensory properties, including texture, flavour, taste, product shape and size, improved the percentage of variance explained in child mealtime behaviours and overall disposition over the base model (containing no sensory modalities), with texture having the largest influence. Overstuffing the mouth, a challenging eating behaviour, was most influenced by product texture (children ≥ 30 months), and product texture and size (children < 30 months). In both age groups, coughing/choking/gagging was most influenced by food texture and was associated with a product that was grainy and angular (sharp corners). In both age groups, product acceptance was associated with a product that was dissolvable, crispy, and savoury while rejection was associated with a dense, gummy and fruity product. These results suggest that a dissolvable, crispy texture, with a cheesy or buttery flavour are the sensory properties important in a desirable flavoured commercial snack product for children with DS; however, overall disposition must be balanced against mouth overstuffing.

Feeding Stressors and Resources Used by Caregivers of Children With Down Syndrome: A Qualitative Analysis

BACKGROUND

Challenging eating behaviors or feeding difficulties, commonly displayed in children with Down syndrome (DS), may amplify perceived stress in caregivers. If caregivers lack resources on how to accommodate the needs of the child with DS, they may find feeding the child stressful and resort to negative coping strategies.

OBJECTIVE

The aim of this study was to understand the feeding stressors, resources, and coping strategies used by caregivers of children with DS.

DESIGN

A qualitative analysis of interview transcripts was undertaken, framed around the Transactional Model of Stress and Coping.

PARTICIPANTS/SETTING

Between September to November 2021, 15 caregivers of children (aged 2 through 6 years) with DS, were recruited from 5 states located in the Southeast, Southwest, and West regions of the United States.

ANALYSIS

Interviews were audio-recorded, transcribed verbatim, and analyzed using deductive thematic analysis and content analysis approaches.

RESULTS

Thirteen caregivers reported increased stress around feeding the child with DS. Stressors identified included concern about adequacy of intake and challenges associated with feeding difficulties. Stress related to feeding was higher among caregivers whose child was learning a new feeding skill or in a transitional phase of feeding. Caregivers used both professional and interpersonal resources in addition to problem- and emotion-based coping strategies.

CONCLUSIONS

Caregivers identified feeding as a stressful event with higher stress reported during transitional phases of feeding. Caregivers reported that speech, occupational, and physical therapists were beneficial resources to provide support for optimizing nutrition and skill development. These findings suggest that caregiver access to therapists and registered dietitian nutritionists is warranted.

Co-occurring conditions in Down syndrome: Findings from a clinical database

Individuals with Down syndrome (DS) experience a range of medical and neurodevelopmental conditions, necessitating systematic study of their occurrence and impact on neurodevelopmental outcomes. We describe the prevalence and relationships of medical, neurodevelopmental (ND), and mental health (MH) conditions in children with DS. We created a prospective clinical database of individuals with DS, integrated into the workflow of a specialty Down Syndrome Program at a specialty pediatric referral hospital. Conditions were collected through caregiver- and clinician report at clinical visits (N = 599). We calculated frequencies of medical, ND, and MH conditions and then assessed the relationship between medical, ND, and MH conditions using frequencies and comparative statistics. The most frequent co-occurring conditions were vision (72.5%), ear/hearing (71.0%), gastrointestinal (61.3%), respiratory (45.6%), and feeding (33.6%) problems, with variation in frequency by age. ND and MH conditions were reported in one quarter, most commonly autism spectrum disorder and attention-deficit/hyperactivity disorder. Those with ND and MH conditions had greater frequency of medical conditions, with highest rates of vision, ear/hearing, and gastrointestinal issues, and CHD. Systematically collected clinical data in a large cohort of children with DS reveals high prevalence of several co-occurring medical, ND, and MH conditions. Clinical care requires an understanding of the complex relationship between medical conditions and neurodevelopment.

A Scoping Review of the Complementary Feeding Practices and Early Eating Experiences of Children With Down Syndrome

OBJECTIVE

Children with Down syndrome may experience more challenges in their early feeding and may be introduced to complementary foods comparatively later than typically developing (TD) children. This scoping review aimed to identify and synthesize the existing literature that describes feeding problems and early eating experiences relating to the period of complementary feeding for children with Down syndrome.

METHODS

Scopus, PubMed, Medline, Web of Science, and PsycInfo were searched. Journal articles published between January 1991 and June 2022 that reported on the complementary feeding period with children with Down syndrome were included.

RESULTS

Eighteen journal articles met the inclusion criteria. Children with Down syndrome were introduced to complementary foods later than TD children and progressed to more challenging food textures at a slower rate. Gross and fine motor skill delays and sensory difficulties contributed to secondary feeding problems such as difficulties chewing, biting, and reduced awareness of food on lips and tongue. Parents of children with Down syndrome reported exercising more caution and employing more controlling feeding practices compared to TD and had higher levels of concern regarding their child's weight.

CONCLUSIONS

Guidelines and early feeding support specific to children with Down syndrome should be available before the first complementary foods are introduced and throughout this period. Feeding support should aim to address parental concerns and provide assistance when feeding problems occur, to minimize delays and encourage the optimum development of eating abilities. Future research should address the development of feeding problems during this period and explore possible interventions.

Clinical Validation of Feeding Handicap Index for Children (FHI-C)

Children with developmental disabilities (DD) exhibit feeding and swallowing difficulties, which can have an impact on nutritional, developmental, and psychological aspects. The existing tools assess the nature of feeding problems and behaviors only. The present study aimed to assess the physical, functional, and emotional domains in children with DD with feeding issues using Feeding handicap index for children (FHI-C). For clinical validation, FHI-C was administered on the parents/caregivers of 60 children with cerebral palsy, 61 with autism spectrum disorder, 59 with intellectual disability and 60 typically developing children in the age range of 2 to 10 years. The results revealed that the mean scores (Total FHI-C and FHI-C domain scores) were significantly higher for all three clinical groups than for the control group, which revealed good clinical validity. Also, FHI-C was found to have significantly high test-retest reliability. The study presents a valid and reliable tool for assessing the psychosocial handicapping effects of feeding problems in children with DD. FHI-C provides a holistic picture about the psychosocial impact of feeding problems in children with DD and will assist the clinicians in prioritizing the goals for feeding therapy. The scores obtained can be used as reference for pre and post therapy comparison purposes.

Comparison of the malocclusion and orthodontic treatment needs of Down syndrome and non-syndromic subjects by using the dental aesthetics index

OBJECTIVE

To evaluate the prevalence and significance of the malocclusion traits and orthodontic treatment needs of Down syndrome (DS) subjects with matched non-syndromic (NS) controls.

METHODOLOGY

This cross-sectional study involved 222 subjects (50% DS, 50% NS) who were matched by gender and age. The casts were digitized into three-dimensional images. These images were used alongside the ten occlusal characteristics of the Dental Aesthetic Index (DAI) to determine malocclusion severity and the need for orthodontic treatment.

RESULTS

There were 58 (52.3%) females and 53 (47.7%) males with a mean age of 18.4 ± 8.4 years in both groups. The most common and significant (p < .05) malocclusion traits among the DS subjects were missing teeth (56.2%), incisal spacing segments (73.0%), anterior maxillary irregularity (95.5%), mandibular overjet (36.0%), and full cusp deviation of the molar relationship (61.3%). On the other hand, increased maxillary overjet (69.3%) is a more significant (p < .05) trait amongst NS subjects. There were 85 (76.6%) DS subjects who presented severe malocclusion, which implies a highly orthodontic treatment need (DAI > 30). The DS showed some impact of malocclusion traits components of the DAI.

CONCLUSION

The occurrence of malocclusion was higher in DS, implying a higher need for orthodontic treatments than for NS subjects.

Navigating a Complex Presentation: Management of Hypernatremic Dehydration, Acute Kidney Injury, Hyperkalemia, and Metabolic Acidosis in a Patient With Down Syndrome: A Case Report

Worldwide, gastroenteritis is a well-known cause of dehydration in pediatric patients and can be life-threatening due to subsequent electrolyte disturbance or dehydration itself. In this case, we present an infant with Down syndrome (karyotype: 21 trisomy) who presented to us with moderate hypernatremic dehydration associated with severe hyperkalemia, moderate metabolic acidosis (pH: 7.1, random blood glucose: 80-110 mg/dL), and elevated kidney function tests secondary to the gastroenteritis caused by Entamoeba histolytica infection. The patient is being followed up by the pediatrics genetics clinic for growth and development, with regular screening for thyroid and celiac diseases, and he has no major heart, gastrointestinal, or renal anomalies. This unique and complex presentation of electrolyte disturbance and dehydration associated with a susceptible condition of Down syndrome deserves special attention with precise management which can be challenging. We managed the patient as a case of hypernatremic dehydration with gradual correction of serum sodium and dehydration, while concurrently managing hyperkalemia by routine methods (beta agonist inhalers, insulin, dextrose 10%) with close laboratory and clinical monitoring at the pediatric intensive care unit. The pediatric nephrology team was also consulted while delineating the management plan. As the patient's condition eventually resolved with normal kidney function and electrolytes, metabolic acidosis also resolved, with good oral intake and urine output, stable vitals, and was discharged after 72 hours. In conclusion, this case showed that pediatric patients with susceptible conditions such as Down syndrome with gastroenteritis can present with a lethal combination of dehydration and/or electrolyte disturbance, making close monitoring and prompt management paramount in such cases.

Parental perception of facilitators and barriers to health among young children with down syndrome: a qualitative study

Background

Despite high rates of obesity and weight-related conditions observed in children with Down syndrome, little is known about how to prevent these conditions.

Purpose

The purpose of this study was to identify parent-perceived facilitators and barriers to health for toddlers (12-36 months old) with Down syndrome.

Materials and methods

We conducted in-depth, semi-structured interviews with the mothers of 25 toddlers with Down syndrome. All interviews were conducted using Zoom Video Technology, audio recorded and transcribed before being coded in NVivo software using a structured protocol. Thematic analysis was used to identify themes in perceived facilitators and barriers to health at the level of the child, family, and community. Data were triangulated using reflective journaling, video review of child meals, and member-checking techniques.

Results

We identified unique themes for facilitators (on the move and sound sleep) and barriers (co-occurring conditions and eating behaviors) at the level of the child. At the level of the family and community, overarching themes that were viewed as either a facilitator or barrier, depending on the context, were identified (role models matter, time is critical, the importance of place, and social support).

Conclusion

These themes can help clinicians and researchers tailor their health promotion interventions to meet the unique needs of children with Down syndrome by using strength-based approaches and providing families with the tools to overcome barriers.

A biophysiological framework exploring factors affecting speech and swallowing in clinical populations: focus on individuals with Down syndrome

Speech and swallowing are complex sensorimotor behaviors accomplished using shared vocal tract anatomy. Efficient swallowing and accurate speech require a coordinated interplay between multiple streams of sensory feedback and skilled motor behaviors. Due to the shared anatomy, speech and swallowing are often both impacted in individuals with various neurogenic and developmental diseases, disorders, or injuries. In this review paper, we present an integrated biophysiological framework for modeling how sensory and motor changes alter functional oropharyngeal behaviors of speech and swallowing, as well as the potential downstream effects to the related areas of language and literacy. We discuss this framework with specific reference to individuals with Down syndrome (DS). Individuals with DS experience known craniofacial anomalies that impact their oropharyngeal somatosensation and skilled motor output for functional oral-pharyngeal activities such as speech and swallowing. Given the increased risk of dysphagia and "silent" aspiration in individuals with DS, it is likely somatosensory deficits are present as well. The purpose of this paper is to review the functional impact of structural and sensory alterations on skilled orofacial behaviors in DS as well as related skills in language and literacy development. We briefly discuss how the basis of this framework can be used to direct future research studies in swallowing, speech, and language and be applied to other clinical populations.

Dysphagia severity is associated with worse sleep-disordered breathing in infants with Down syndrome

STUDY OBJECTIVES

Hypotonia, commonly seen in infants with Down syndrome (I-DS), can contribute to masticatory and oropharyngeal muscle weakness, increasing the risk for dysphagia and sleep-disordered breathing. Data describing the occurrence of dysphagia and sleep-disordered breathing in I-DS are limited. This study aims to determine the frequency and severity of dysphagia and its relationship to polysomnogram parameters in I-DS.

METHODS

We included I-DS who underwent polysomnography at a single academic center over a 6-year period. Data collected included sex, age, presence of dysphagia (low suspicion of dysphagia vs dysphagia vs feeding tube), and polysomnographic data. Dysphagia was determined by a video fluoroscopic swallow study in the presence of clinical suspicion.

RESULTS

A total of 40 I-DS were identified (mean age 6.6 months ± 3; male 65%). There were 11, 13, and 16 I-DS with low suspicion of dysphagia, dysphagia, and feeding tube, respectively. Obstructive sleep apnea was more severe in I-DS in the feeding tube group when compared with the group with a low suspicion of dysphagia and (apnea-hypopnea index mean [standard error] = 49.3 [7.6] vs 19.2 [9.2] events/h; P = .016). Dysphagia severity was positively correlated with a higher obstructive apnea-hypopnea index (r = .43, P = .006).

CONCLUSIONS

There is a high incidence of dysphagia and sleep-disordered breathing in I-DS. Dysphagia severity correlated with obstructive apnea-hypopnea index severity. Our results suggest that I-DS need early evaluation of both sleep-disordered breathing and dysphagia.

The experiences of new mothers accessing feeding support for infants with down syndrome during the COVID-19 pandemic

Infants with Down syndrome are more likely to experience feeding problems and mothers are likely to require more feeding support than mothers of typically developing infants. During the COVID-19 pandemic, many feeding support services changed from face-to-face to online, which impacted some maternal feeding experiences negatively, but no studies to date have explored the impact for mothers of infants with Down syndrome. Thematic analysis was conducted on semi-structured interviews from thirteen new mothers of infants (aged 8-17 months) with Down syndrome in the UK. Three superordinate themes were generated: (1) Every baby with Down syndrome has a unique journey, (2) There's no point asking, they won't know, (3) Lack of in-person support. Many mothers expressed frustrations over health professionals' lack of Down syndrome specific knowledge resulting in unmet needs, further magnified due to the nature of the virtual support being offered. Moreover, mothers struggled with reduced social support from other mothers when encountering feeding problems. These results hold real-world implications for health professionals who could provide more specialised face-to-face feeding support to mothers of infants with Down syndrome. This should be prioritised for children's overall development and mothers' wellbeing.

Eating behaviors in children with down syndrome: Results of a home-use test

Children with Down syndrome (DS) display a disproportionate number of health challenges, including feeding and swallowing difficulties and food texture sensitivities. To start addressing food texture challenges early in life, the aim of this research was to understand mealtime behaviors and identify preferred food textures of children with DS. Children (aged 11 to 58 months) with DS (n = 111) and without (typically developing, TD; n = 107) participated in a home use test evaluating snack products of varying textures. Parents recorded their children's reactions to each food product; a panel of trained coders coded videos for mealtime behaviors. Children were also identified as food texture sensitive (TS) or non-texture sensitive (NTS). Results showed that age, TS, the presence of a DS diagnosis and the TS*DS interaction influenced the child's behaviors to the food products. Children with DS were more likely to increase distance from the food, mouth/suck on the food, and less likely to chew/much on the food compared to children TD. Children with DS also ate significantly less than typically developing children. Similar mealtime behaviors were observed between the children with TD/<30 months of age and children with DS regardless of age (p < .05). While children with DS/TS had a higher disposition for the dissolvable texture, along with products that were salty and cheesy, children with DS/NTS had a greater tolerance for more textures in general, including crunchy and grainy. Overall, this research identified mealtime behaviors in children with DS, determined overall disposition of children with DS to foods of differences sensory properties, and demonstrated the influence of TS on a child's disposition to a food. This research will be extended to develop acceptable and innovative food products for children with DS/TS.

Pediatrics for Disability: A Comprehensive Approach to Children with Syndromic Psychomotor Delay

Intellectual disability is the impairment of cognitive, linguistic, motor and social skills that occurs in the pediatric age and is also described by the term "mental retardation". Intellectual disability occurs in 3-28 % of the general population due to a genetic cause, including chromosome aberrations. Among people with intellectual disabilities, the cause of the disability was identified as a single gene disorder in up to 12 %, multifactorial disorders in up to 4 %, and genetic disorders in up to 8.5 %. Children affected by a malformation syndrome associated with mental retardation or intellectual disability represent a care challenge for the pediatrician. A multidisciplinary team is essential to manage the patient, thereby controlling the complications of the syndrome and promoting the correct psychophysical development. This requires continuous follow-up of these children by the pediatrician, which is essential for both the clinical management of the syndrome and facilitating the social integration of these children.

Relationships between feeding problems, eating behaviours and parental feeding practices in children with Down syndrome: A cross-sectional study

BACKGROUND

Research investigating feeding problems in children with Down syndrome is scarce. This study investigated feeding problems, eating behaviours and parental feeding practices in children with Down syndrome (n = 40), and typically developing (TD) children of the same age and sex (n = 40).

METHOD

Parents of children aged 6-months to 5-years in the UK completed questionnaires assessing their child's feeding problems and eating behaviours and parental feeding practices.

RESULTS

For children with Down syndrome, feeding problems were: significantly greater than for TD children; negatively associated with breast milk duration and appetite during exclusive milk feeding; and positively associated with drinking more slowly. For both groups, feeding problems were significantly correlated with more food avoidant eating behaviours.

CONCLUSIONS

This study provides new information about the relationships between feeding problems and eating behaviours in early development. Longitudinal research is needed to further investigate these relationships, so that effective support can be developed for families.

Development and application of specific questions to classify a child as food texture sensitive

Understanding food texture sensitivity in children is important in guiding food selection. The objective of this work was to develop a short questionnaire that could be completed by parents in nonclinical settings to provide a categorization for food texture sensitivity in children. This study evaluated the distribution of children as texture sensitive (TS) or non-texture sensitive (NTS) and the predictive validity of these questions to explain rejection of specific food textures. Three sets of survey data were examined, including data from a home-use test (HUT) in children with and without Down syndrome (DS), and lingual tactile sensitivity measured by grating orientation task (GOT). From three parent-completed surveys, the use of the questionnaire yielded a similar distribution of children in the TS category (16-22%) as previously reported. TS children (4-36 months) were more likely to reject specific food textures, including chewy, hard, lumpy, and "tough meat" (p < .05). A higher percentage of children with a diagnosis of DS were TS (36.9%). Children who were TS showed increased negative behaviors to foods and ate less than NTS children. In older children (5-12 years), TS children were fussier than NTS children (p < .001). Lingual tactile sensitivity was not significantly different by TS/NTS categorization (p = .458). This study demonstrated that the use of these five questions specific to food texture provides a useful tool in categorizing a child as TS/NTS, with this information being useful in selecting preferred food textures. Future studies involving these TS questions should perform psychometric assessments and measures of criterion validity using other questionnaires.

Comparing the Tongue and Lip Strength and Endurance of Children with Down Syndrome with Their Typical Peers Using IOPI

Muscular hypotonia is a feature of Down syndrome (DS), and it affects the tongue and lips. A study on oral dysfunction in children with DS concluded that most of them did not have the tongue strength for completing the oral phase of swallowing. Recognizing the weakness of the oral muscles and improving its motor function positively affects mastication and swallowing, and prevents complications. This cross-sectional study aimed to measure the lip and tongue strength and endurance of children with DS and their typical peers, and compare these two groups with each other using Iowa Oral Performance Instrument (IOPI). Eight children with DS and 33 typical children aged 8-13 years were enrolled in this study. To examine the effect of age on the tongue strength and endurance, we divided the children into three groups of 8-9, 10-11, and 12-13 years old. The results showed that both anterior and posterior tongue strength were significantly lower in children with DS (p = 0.004 and 0.003). But, it was not the case with tongue endurance. Also, in 10-11 years old age group, the mean posterior tongue strength and in 12-13 years old age group the lip endurance was significantly lower in children with DS (p = 0.05 for both). Lips strength and endurance were both remarkably lower in children with DS (p = 0.004 and 0.02). In this study, tongue, and lip strength and endurance in both children with DS and typical ones were measured with IOPI for the first time. Moreover, it provided quantitative data on the strength and endurance of the muscles of the tongue and lips, which can contribute to future studies.
