RESUMO

Abstract Objective To assess FEES findings in defining oral feeding safety in children with suspected dysphagia, comparing them with clinical feeding evaluation results. Methods This study comprised a case series involving children with suspected dysphagia, referred for evaluation by otolaryngologists and speech-language pathologists (SLPs) at a Brazilian quaternary public university hospital. These children underwent both clinical evaluations and fiberoptic endoscopic evaluation of swallowing (FEES), with a comprehensive collection of demographic and clinical data. Subsequently, the authors performed a comparative analysis of findings from both assessments. Results Most patients successfully completed the FEES procedure (93.7%), resulting in a final number of 60 cases included in the study. The prevalence of dysphagia was confirmed in a significant 88% of these cases. Suspected aspiration on clinical SLP evaluation was present in 34 patients. Of these, FEES confirmed aspiration or penetration in 28 patients. Among the 35 patients with aspiration or penetration on FEES, 7 (20%) had no suspicion on SLP clinical assessment. All seven patients in whom clinical SLP evaluation failed to predict penetration/aspiration had neurological disorders. The median age of the children was 2.8 years, and 49 (81.6%) had neurological disorders, while 35 (58.3%) had chronic pulmonary disease. The most prevalent complaints were choking (41.6%) and sialorrhea (23.3%). Conclusion FEES can diagnose structural anomalies of the upper aerodigestive tract and significantly contribute to the detection of aspiration and penetration in this group of patients with suspected dysphagia, identifying moderate and severe dysphagia even in cases where clinical assessment had no suspicion.

RESUMO

Introduction: The gag reflex is a protection mechanism that prevents food and unwanted agents from entering the lower airways. It is usually part of the physical examination of swallowing to detect oropharyngeal dysphagia, but it is a potentially ambiguous sign. Objective: To evaluate the diagnostic value of the gag reflex in patients with neurogenic oropharyngeal dysphagia and adults without it. Materials and methods: We conducted an analytical observational study in patients with neurogenic oropharyngeal dysphagia (cases) and patients without dysphagia (controls). We evaluated the absence or presence of the reflex bilaterally, by direct visualization, and adjusted it according to sex, age, and other interaction variables. Results: We included 86 patients with neurogenic oropharyngeal dysphagia and 80 control subjects. The gag reflex on swallowing physical examination showed a positive relationship with the patients (right side: OR = 3.97; 95 % CI: 2.01-7.84; left side: OR = 4.84; 95 % CI: 2.41-9.72), but a negative association with the control group. In both groups, neither sex, nor age, nor other interaction variables modified the gag reflex. Conclusions: The gag reflex absence or presence does not confirm or exclude the existence of oropharyngeal dysphagia due to neurological and neuromuscular causes. Therefore, health professionals must not rely on this reflex. Clinicians must go beyond a simple reflex revision, even in neurological patients where it is supposed to be absent.

RESUMO

The factors related to oropharyngeal dysphagia after remote esophagectomy (greater than five months) remain unclear. This study aimed to assess patient perception of dysphagia, maximum anterior isometric pressure (MAIP), maximum posterior isometric pressure (MPIP), lingual swallowing pressure (LSP) and radiographic physiological components of the oral and pharyngeal phases of swallowing in patients who are post remote sub-total esophagectomy (SE). Patient perception of dysphagia was assessed using the Eating Assessment Tool (EAT-10). MAIP, MPIP, and LSP were measured using the Iowa Oral Performance Instrument. Videofluoroscopy was used to assess the physiologic components of swallowing with the Modified Barium Swallow Impairment Profile (MBSImP) and the Penetration-Aspiration Scale (PAS). Ten patients were included in the study (53.2% male; mean age 54.5 ± 18.0). The mean postoperative time was 30 months (range, 5.0-72 months). Seven patients had elevated EAT-10 scores (> 3). All patients demonstrated impaired oropharyngeal swallowing on at least three MBSImP components (range 3-12) and two patients aspirated (PAS 8). There was a significant difference in MAIP values when comparing patients with normal versus impaired laryngeal elevation and epiglottic movement (p < 0.001). MPIP values were significantly different in patients with normal versus impaired epiglottic movement as well as normal versus elevated PAS scores (p < 0.001). Decreased lingual pressure and physiological changes in swallowing coexist after SE. Our results indicate that the decrease in tongue strength may be one of the factors related to unsafe swallow. The assessment of lingual pressure provides diagnostic value and should be incorporated as part of a comprehensive assessment in this population.

RESUMO

OBJECTIVE: To describe the findings of children with Robin Sequence (RS) who received sensory-motor-oral stimulation combined with early sucking during mandibular distraction osteogenesis (MDO), compared with children who did not receive the intervention. DESIGN: A quasi-experimental study. Setting: A tertiary public hospital. Patients: Children with RS referred to MDO. A historical group from the same population but managed according to the institution's standard protocol (no sucking) served as a control group. Interventions: Sensory-motor-oral stimulation, including sucking, starting 24 h after MDO (intervention group). Main Outcome Measure: Our hypothesis is that sensory-motor-oral stimulation, including sucking during the DOM process, do not negatively affect surgical outcomes. RESULTS: Twenty-nine children were included. Eight (72.7%) of the 11 patients in the intervention group and 13 (72.2%) of the 18 controls had MDO complications, with no significant difference between the groups (p = 1.000). The most common surgical outcome was antibiotic therapy for surgical site infection (76.2%). Six months after MDO, 22 (75.9%) children attained full oral feeding or associated with alternative feeding methods. CONCLUSION: The intervention group did not have higher complication rates, from a surgical point of view, than control group. The protocol adopted by some centers that contraindicates sucking during MDO should be revised to consider the benefits of such stimulation. Keywords: Pierre Robin Syndrome, deglutition, therapeutics, child development.

RESUMO

OBJECTIVE: To report the process of translation and cross-cultural adaptation of theYale Pharyngeal Residue Severity Rating Scale into Brazilian Portuguese. METHODS: Methodological study approved by the Ethics Committee of the Institution (nº 5.166.256). The English original scale was translated into Brazilian Portuguese following suggested in the literature guidelines and recommendations after authorization from the authors of the original instrument, and involved the following reported steps of (1) Translation, (2) Synthesis of translations, (3) Determination of the applicability of the translated version 4) Back-translation, (5) Synthesis of the back-translated versions, and (6) Final synthesis. The translations and back-translations were performed by two bilingual translators. The research committee constituted three specialists who considered whether the linguistic, semantics, conceptual, idiomatic, and contextual equivalence of the translations and back-translations were. In Step 3, the raters consisted of three Speech-Language Pathologists and five ENT physicians divided into two subgroups (less than 5 years of professional expertise, and more than 5 years of professional expertise). RESULTS: Step 1 was carried out properly by the translators, in Step 2 the translated version was prepared after minor adjustments. In Step 3, the raters reported that they found no difficulties in applying the scale. The Cronbach's Alpha coefficient was 0.995, demonstrating high internal consistency of the instrument, and the analysis of the Intraclass Correlation Coefficient (ICC) among the eight raters was 0.994 with a confidence interval between 0.990 and 0.998, demonstrating excellent agreement, regardless of experience. The research committee judged the last to be adequate and not to require adjustments. CONCLUSION: The Brazilian Portuguese version of theYale Pharyngeal Residue Severity Rating Scale is presented in this study. This is a methodological study - No level of evidence.

RESUMO

Aspiration detected in the fiberoptic endoscopy evaluation of swallowing (FEES) has been inconsistently associated with pneumonia, with no evidence of the risk of pneumonia from other alterations in swallowing safety detected in FEES. We conducted a dynamic, ambidirectional cohort study involving 148 subjects at risk of dysphagia in a tertiary university hospital. Our aim was to determine the risk of pneumonia attributed to alterations in swallowing safety detected during FEES. We used multivariate negative binomial regression models to adjust for potential confounders. The incidence density rate (IR) of pneumonia in patients with tracheal aspiration of any consistency was 26.6/100 people-years (RR 7.25; 95% CI: 3.50-14.98; P < 0.001). The IR was 19.7/100 people-years (RR 7.85; 95% CI: 3.34-18.47; P < 0.001) in those with laryngeal penetration of any consistency and 18.1/100 people-years (RR 6.24; 95% CI: 2.58-15.09; P < 0.001) in those with pharyngeal residue of any consistency. When adjusted for aspiration, the association of residue and penetration with pneumonia disappeared, suggesting that their risk of pneumonia is dependent on the presence of aspiration and that only aspiration is independently associated with pneumonia. This increased risk of pneumonia was significant in uni- and multivariate negative binomial regression models. We found an independently increased risk of pneumonia among patients with dysphagia and aspiration detected during FEES. Alterations in the oral and pharyngeal phases of swallowing, without aspiration, did not increase the risk of pneumonia.

Introduction: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication, changes in sensitivity and eating difficulties. Objective: To carry out an integrative review of swallowing changes in individuals with ASD. Methods: The research was carried out through a search for national and international articles, using descriptors for the research, as well as inclusion and exclusion criteria for selecting the final sample. The PPOT strategy was used to define eligibility criteria, including population (children and adults), predictor (ASD diagnosis), outcome (report or diagnosis of dysphagia oral, pharyngeal or esophageal), and study type (observatory studies). The search was carried out from June to August 2023, in the databases: Pubmed, Scopus, Embase and Google Scholar. Results: Ten studies were selected with patients diagnosed with ASD who reported symptoms of oropharyngeal and esophageal dysphagia, in addition to complaints about food intake. Studies suggest that children with ASD may present problems with oral motor dysfunction, inadequate eating frequency, obsessive eating patterns, specific presentation of certain foods, food selectivity and sensory processing difficulties. Conclusion: It is concluded that there is no robust scientific evidence about the presence of dysphagia in patients with ASD. (AU)

RESUMO

BACKGROUND: Limited data exist on the mid- to long-term masticatory capacity of mandibular overdenture (IOD) wearers, particularly regarding the use of posterior implants to retention. OBJECTIVES: To periodically evaluate mastication of IOD wearers, comparing the effectiveness of two to four implants to retain the prosthesis. METHODS: In a randomised controlled clinical trial, 20 complete edentulous patients (14 women), aged 51-84 years (mean age 69.1 ± 9.6), received new bimaxillary complete dentures (CD). After adaptation, baseline measurements of masticatory performance (X50) and swallowing threshold were conducted using the sieving method. Patients were then randomly assigned to groups: control (two intra-foraminal regular implants) and experimental (two intra-foraminal regular implants and two extra-short posterior implants) (n = 10 each). After 4 months, implants were splinted, and a new mandibular IOD was fabricated with bar/clip retention. Mastication was reassessed after 6, 12, and 48 months, and data analysed with repeated measures ANOVA and Sidak's post hoc (α = 0.05). RESULTS: Despite a loss of two patients per group, masticatory performance significantly improved after mandibular IOD installation (p = .031) in both groups (p = .670). A second improvement was observed after 6 months (p = .027), with no subsequent changes (p > .05). Swallowing threshold improvements were noted with IOD, and no discernible differences between groups were observed (p > .05). CONCLUSION: Masticatory function significantly improved after mandibular IOD installation, with the number of implants demonstrating minimal influence. CLINICAL TRIAL REGISTRATION: The present study was not registered in a public database, as mandated. It is important to note that the recommendation for registration was initiated in 2017 by the Committee of Medical Journal Editors, while patient inclusion in the research took place in 2016. Given that the data presented in this manuscript cover a follow-up period of up to 4 years post-surgical intervention, delayed registration was not feasible.

RESUMO

This scoping review aimed to identify methodological procedures for acquiring and analyzing ultrasound images related to swallowing in adults and older adults. The inclusion criteria were based on the PCC strategy (participants, concept, and context), as follows: population (adults and older adults), concept (ultrasound assessment), and context (swallowing assessment). The review included observational, experimental, descriptive, and analytical studies and excluded those that were not available in full, animal studies, in vitro studies, letters to the editor, errata, study protocols, and those that used ultrasound for purposes other than swallowing. There were no language and time restrictions. Two independent blinded professionals selected 81 articles that met the inclusion criteria from different databases. The most evaluated parameters included tongue morphology and movements, hyoid bone displacement, swallowing muscle area, and pharyngeal residue detection, such as pharyngeal wall mobility. They used convex and linear transducers (3 MHz to 8 MHz) positioned in the submental, laryngeal, and lateral regions of the neck. The subjects were seated and instructed to eat different food volumes and consistencies. The literature mapping showed that ultrasound is a promising diagnostic tool, helping clinicians understand swallowing disorders, as it provides static and dynamic images in different modes and positions. Also, patients receive real-time biofeedback of changes related to dysphagia.

RESUMO

OBJECTIVE: To classifying the degree of swallowing impairment in the elderly, comparing clinical and instrumental assessment. METHODS: This is a cross-sectional study with quantitative and qualitative analysis of clinical and instrumental assessment of 37 elderly, aged 60-82 years, of both genders without neurological, oncological or systemic diseases, participated in this study. All participants were submitted to clinical evaluation and their results compared through fiberoptic endoscopic evaluation of swallowing considering liquid, pudding and solid food consistencies. Data were analyzed descriptively and statistically using the analysis of variance test (two-way ANOVA) and Tukey's post hoc test (p <  0.05). RESULTS: In the clinical evaluation there was a higher occurrence of moderate swallowing impairment, followed by functional swallowing, while in fiberoptic endoscopic evaluation of swallowing the severity of the impairment was greater for moderate and mild degrees. There was no statistical difference between the clinical and instrumental evaluation methods. However, there was a significant interaction between the variables, with a difference for liquid consistency in the instrumental evaluation method. CONCLUSION: Healthy elderly have different degree of swallowing impairment according to food consistency. The clinical assessment using a scale that considers the physiological changes of the elderly, presented results similar to those found in the instrumental examination.

RESUMO

SUMMARY: The thyrohyoid muscle is one of the four infrahyoid muscles. Its role in vocalization and deglutition could be often overlooked, despite its crucial participation in these processes. Unlike other infrahyoid muscles, the thyrohyoid muscle receives innervation from the first cervical spinal nerves which contributes to its unique function. Its primary action involves hyolaryngeal elevation during swallowing, contributing to the opening of the upper esophageal sphincter. In conjunction with other muscles, it also protects the airway and facilitates the passage of food into the esophagus. Variations in the muscle's thickness may exist, and its function can be influenced by chewing habits. Weakened muscles involved in swallowing are often associated with dysphagia, a common complication in stroke and brain-injured patients. Advanced imaging techniques and sleep studies have provided insights into the dynamics and frequency of swallowing. This review explores the anatomic structures, function in action, diagnosis and clinical implications of this muscle. Overall, understanding the significance of the thyrohyoid muscle enhances our comprehension of the intricate interplay of laryngeal muscles during vocalization and deglutition.

El músculo tirohioideo es uno de los cuatro músculos infrahioideos. A menudo podría pasarse por alto su papel en la vocalización y la deglución, a pesar de su participación crucial en estos procesos. A diferencia de otros músculos infrahioideos, el músculo tirohioideo recibe inervación de los primeros nervios espinales cervicales, lo que contribuye a su función única. Su acción principal implica la elevación hiolaríngea durante la deglución, contribuyendo a la apertura del esfínter esofágico superior. Junto con otros músculos, también protege las vías respiratorias y facilita el paso de los alimentos al esófago. Pueden existir variaciones en el grosor del músculo y su función puede verse influenciada por los hábitos de masticación. Los músculos debilitados involucrados en la deglución a menudo se asocian con disfagia, una complicación común en pacientes con accidente cerebrovascular y lesión cerebral. Las técnicas de imagen avanzadas y los estudios del sueño han proporcionado información sobre la dinámica y la frecuencia de la deglución. Esta revisión explora las estructuras anatómicas, la función en acción, el diagnóstico y las implicaciones clínicas de este músculo. En general, comprender la importancia del músculo tirohioideo mejora nuestra comprensión de la intrincada interacción de los músculos laríngeos durante la vocalización y la deglución.

RESUMO

Objective: We aimed to determine the prevalence of self-reported swallowing difficulty (dysphagia) among older Colombians and to explore the factors associated with this condition. Methods: This study presents a secondary analysis of the SABE-Colombia survey, a crosssectional study of community-dwelling older adults. The dependent variable was self reported swallowing difficulty, assessed through the question: "How often do you have difficulty or discomfort swallowing?" Descriptive and bivariate analyses of the sample were performed, followed by multivariate analysis, adjusting for confounding variables. Results: The final sample included 19 004 older Colombians, whose mean age was 69 years (56% women). The overall prevalence of swallowing difficulty was 12.2%. In the multivariate analysis, significant associations were observed between swallowing difficulty and several factors, including male sex (OR 1.14, 95%CI 1.03 ­ 1.26), age > 80 years (OR 1.26, 95%CI 1.08 ­ 1.47), dependence in activities of daily living (OR 1.62, 95%CI 1.23 ­ 2.13), cognitive impairment (OR 1.49, 95%CI 1.30 ­ 1.70), depressive symptoms (OR 1.38, 95%CI 1.15 ­ 1.65), sarcopenia (OR 1.32, 95%CI 1.02 ­ 1.69), malnutrition (OR 1.35, 95%CI 1.23 ­ 1.49), and osteoarticular disease (OR 1.18, 95%CI 1.07 ­ 1.38). Conclusion: There was a high prevalence of swallowing difficulty among older community-dwelling Colombians. Our results showed a strong correlation between swallowing difficulty and risk factors such as cognitive impairment, depressive symptoms, osteoarticular disease, and dependence in activities of daily living, but not with malnutrition or sarcopenia.

RESUMO

This case study presents a female patient with progressive dysphagia for solids, heartburn, and obesity that proved refractory to clinical management. Imagenological diagnosis revealed esophageal stenosis and achalasia. Furthermore, metabolic syndrome was established. We proposed intervention through esophagogastric reconstruction due to stenosis, revision of cardiomyotomy and robotic gastric bypass revealing scar tissue and fibrosis on the anterior aspect of the stomach resulting from prior fundoplication surgery. The patient underwent esophagogastric reconstruction due to adhesion bands which conditioned partial angulation of the gastroesophageal junction, cardiomyotomy revision, anterior and posterior hiatal plasty, and Roux Y Gastric Bypass assisted by a robot without complications. The intervention resulted in significant improvement in postoperative symptoms. This case highlights the importance of considering the probability of mechanical obstruction due to postsurgical adhesions in the initial evaluation of recurrent and persistent dysphagia, with surgical reintervention being the ideal option for resolution.

RESUMO

Open Partial Horizontal Laryngectomy (OPHL) Type IIa surgery is a conservative surgical technique used in the treatment of laryngeal carcinomas. In this pilot study, we aimed to characterize swallowing function and physiology in a series of patients after OPHL Type IIa surgery through comparison to healthy reference values for quantitative measures for videofluoroscopy. We performed retrospective quantitative analysis of videofluoroscopy recordings of thin liquid swallows for a preliminary sample of 10 male patients. Each videofluoroscopy clip was rated in triplicate by trained blinded raters according to the ASPEKT Method (Analysis of Swallowing Physiology: Events, Kinematics and Timing). This preliminary sample of patients with previous OPHL surgery showed functional airway protection, with only 2 patients showing incomplete laryngeal vestibule closure (LVC) and associated airway invasion. However, the majority of patients (90%) showed prolonged latencies to LVC and upper esophageal sphincter (UES) opening. Prolonged durations of LVC and UES opening were also noted, but these were in the direction of compensation rather than impairment. Reduced pharyngeal area at rest was seen in 70% of the sample, and all patients showed poor pharyngeal constriction. Post-swallow residue was a prominent finding in ≥ 75% of these patients. In particular, reduced or absent constriction of the hypopharynx in the region of the pyriform sinuses was noted as a characteristic of swallowing in this sample. The data from these patients suggest that despite functional airway protection, severe swallowing dysfunction involving poor pharyngeal constriction and bolus clearance may be likely after OPHL surgery.

RESUMO

The aim of this study was to investigate the measures of displacement, time and velocity of hyoid bone movement in female thyroidectomy patients. Fifty-eight ultrasound videos of 29 women during swallowing were analyzed. The sample was divided into experimental group (EG), composed of 12 women following total or partial thyroidectomy; and control group (CG) of 17 healthy women. The kinematic measures of displacement, time and velocity of hyoid bone displacement were tracked during swallowing of 10 ml of liquid (water) and 10 ml of thickened liquid (honey) in both groups for comparisons. Additional analysis included bolus consistency effect and relationship with clinical characteristics. Ultrasound videos were analyzed according to a standardized protocol using ImageJ software. Displacement, time and velocity of hyoid movement during swallowing of 10 ml of liquid or thickened liquid were not statistically different between female thyroidectomy patients and healthy women. There is no bolus consistency effect on kinematic measures in both groups, but among thyroidectomy patients, velocity of hyoid bone movement is significantly faster in those with swallowing complaints.

RESUMO

Introduction Laryngomalacia is the most common congenital laryngeal alteration, with spontaneous resolution in most cases. However, in the face of more severe presentations of the disease, it is necessary to perform supraglottoplasty surgery. Studies have been dedicated to researching changes in swallowing in children with laryngomalacia before and after surgical intervention. Objectives To identify the prevalence of oropharyngeal dysphagia in children with pre and postsupraglottoplasty laryngomalacia. Data Synthesis A search strategy was developed with terms and entreterms to designate a population pediatric with laryngomalacia , exposure supraglottoplasty , and outcome frequency of dysphagia , adapted to the requirements of the main databases in the health area. The analysis of the records found was performed by two independent examiners and, in the end, 6 articles were included in the study. The articles found enabled a sample of 330 children with laryngomalacia, 311 of whom underwent supraglottoplasty. Among the included studies, 5 were grouped and meta-analyzed. After supraglottoplasty surgery, a 59% reduction in the prevalence of oropharyngeal dysphagia was identified, with high heterogeneity I 2 = 93%. Conclusion Despite the heterogeneity of the sample, the supraglottoplasty procedure significantly reduces the prevalence of dysphagia in children with laryngomalacia.

RESUMO

AIM: To appraise and synthesize research investigating optimizing the administration of solid oral dosage forms (SODFs) to adults with swallowing difficulties. DESIGN: An integrative review. METHODS: An electronic search was conducted on Medical Literature Analysis and Retrieval System Online (Public Medline interface), Elsevier SciVerse Scopus and Scientific Electronic Library Online (updated February 2023). Restriction regarding the publication date was not considered for the inclusion of records. Studies addressing risks, general aspects, recommendations about patient postural adjustments, swallowing techniques, swallowing aids and aspects of concealment of SODFs were included. RESULTS: Fifty-three records published between 2002 and 2021 were included. The main administration risks were aspiration, asphyxia and solid oral dosage form-induced oral/oesophageal mucosal lesions. The most frequent general aspect reported was administering one oral dosage form at a time. The sitting position was the most patient postural adjustment mentioned. The most frequently reported solid oral dosage form swallowing technique was the lean-forward method for capsules. Solid oral dosage form swallowing aids cited: tongue and throat lubricant and solid oral dosage form coating device, swallowing cup and swallowing straw. CONCLUSION: The literature data on administering SODFs for adults with swallowing difficulties were appraised and synthesized. Some aspects, for example, not administering SODFs simultaneously, can make swallowing safer. Postural adjustments and solid oral dosage form swallowing aids are important to avoid administration risks. Swallowing SODFs can be easier if learned by techniques. Liquid and food are helpful as vehicles, and several of these have been listed. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: By optimizing the contributing factors of administering oral pharmacotherapy, the nurse can use appropriate practices to improve patient safety. Additionally, knowing and establishing the administration aspects are reasonable steps for standardizing care for patients with swallowing oral dosage form difficulties. IMPACT: This study addressed administering SODFs to adult patients with swallowing difficulties. The administration of SODFs to adult patients with swallowing difficulties can be optimized if only one oral dosage form at a time is administrated and if patient postural adjustments, swallowing techniques and swallowing aids are used. This investigation will impact the care of patients with swallowing difficulties. REPORTING METHOD: The authors declare they adhered to the relevant EQUATOR guidelines and report following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 Statement. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

RESUMO

To determine the global prevalence of oropharyngeal dysphagia (OD) in adults. Six electronic databases (Embase, LILACS, LIVIVO, PubMed/Medline, Scopus, and Web of Science) were searched, in addition to gray literature (ASHA, Google Scholar, ProQuest Dissertation, and Theses). A random-effects model for meta-analysis of proportions was conducted, and heterogeneity was evaluated according to the moderator variable through subgroup analysis and meta-regression. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist and the certainty of the evidence was assessed using the GRADE tool. Thirty papers were included for qualitative and quantitative synthesis. The combined prevalence estimate was 60% [CI 95% = 50%-70%; I2 = 95%], accounting for different baseline conditions. However, the wide variation that exists between the different baseline conditions (underlying disease or risk factor) tended to overestimate this prevalence when considering the general population. Only one study evaluated healthy individuals, which showed a prevalence of 31% [CI95% = 27%-36%]. The risk of bias was considered low for all studies. None of the variables were considered predictors for the observed variance between the effect sizes of the included studies. For the prevalence of OD, the GRADE rating was considered very low. Despite the high prevalence observed, with over half of the individuals affected, the evidence regarding this outcome remains uncertain due to an overestimation of the generated estimates caused by the baseline condition of the sample.
