Demenech LM, Oliveira AT, Neiva-Silva L, Dumith SC. Prevalence of anxiety, depression and suicidal behaviors among Brazilian undergraduate students: A systematic review and meta-analysis. J Affect Disord 2021; 282:147-159. [PMID: 33418361 DOI: 10.1016/j.jad.2020.12.108] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Revised: 11/16/2020] [Accepted: 12/24/2020] [Indexed: 01/07/2023]
Abstract
BACKGROUND The university context can be an overwhelming background, being especially harmful to undergraduates' mental health. Considering that several studies have reported on the prevalence of psychological distress among Brazilian undergraduate students, this study aimed to conduct a systematic review and meta-analysis of the prevalence and associated factors of anxiety, depression and suicidal behavior in this population. METHODS Studies reporting on the prevalence of anxiety, depression and suicidal behavior and its associated factors among Brazilian undergraduate students were systematically searched in scientific electronic databases. Pooled prevalence was calculated using a random-effects meta-analysis. Individual associated factors were summarized, and study characteristics associated with outcome prevalence were tested through meta-regression analysis. RESULTS Forty-seven articles were included, of which 44 were meta-analyzed (37,486 undergraduates). The pooled prevalence estimates of anxiety, depression and suicidal behavior were 37.75%, 28.51%, and 9.10%, respectively. Meta-regression analysis showed that investigations with probabilistic samples presented a higher prevalence of anxiety and that studies conducted within public institutions and with samples of exclusively medical students presented higher frequencies of depression. LIMITATIONS Cross-sectional data do not allow the establishment of temporality and causal inference. Furthermore, the high heterogeneity of the included studies may also constitute a weakness of this review. CONCLUSIONS The prevalence of anxiety, depression and suicidal behavior among Brazilian undergraduates was high. These results have scientific and practical implications, the former regarding the need for the standardization of the methodology of studies and the latter regarding the need for comprehensive mental health care for Brazilian undergraduates.

Abstract
AIMS To evaluate whether a biobehavioral intervention would be more effective than a self-care intervention or no intervention in reducing psychosocial distress, reducing pain, and improving functioning in patients with an acute myofascial temporomandibular disorder (m-TMD). METHODS Participants (n = 435) were from community dental clinics in the Dallas-Fort Worth Metroplex who were seeking treatment for their acute TMD symptoms and were recruited between 2008 and 2013. The participants were diagnosed using the Research Diagnostic Criteria for TMD (RDC/TMD) and assigned to a biobehavioral intervention, self-care intervention, or no intervention. Three outcomes were assessed: psychosocial distress, pain, and functioning; and treatment effectiveness was assessed according to TMD diagnosis. Outcome evaluations were conducted immediately postintervention as well as at 1 and 2 years postintervention. Analyses were conducted using two-level hierarchical multilevel linear models (MLMs). RESULTS Contrary to expectations, patients did not respond differently to the intervention based on their TMD diagnosis. Acute m-TMD patients, especially those with other comorbid TMD diagnoses, reported the highest levels of pain and pain-related symptoms and disability. They also exhibited poorer jaw functioning, especially if they were at high risk for chronic TMD. CONCLUSION This study indicates that acute m-TMD tends to result in more severe symptom presentations, particularly if diagnosed in combination with other TMD comorbidities. Additionally, patients do not appear to respond better to biobehavioral or self-care intervention on the basis of their TMD diagnosis.

[PMID: 27812883 PMCID: PMC5095086 DOI: 10.1186/s10194-016-0690-1] [Citation(s) in RCA: 60] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2016] [Accepted: 10/14/2016] [Indexed: 01/12/2023] Open
Abstract
Background The objective was to compare and correlate disability, pain intensity, the impact of headache on daily life and the fear of movement between subgroups of patients with chronic temporomandibular disorder (TMD). Methods A cross-sectional study was conducted in patients diagnosed with chronic painful TMD. Patients were divided into: 1) joint pain (JP); 2) muscle pain (MP); and 3) mixed pain. The following measures were included: Craniomandibular pain and disability (Craniofacial pain and disability inventory), neck disability (Neck Dsiability Index), pain intensity (Visual Analogue Scale), impact of headache (Headache Impact Test 6) and kinesiophobia (Tampa Scale of Kinesiophobia-11). Results A total of 154 patients were recruited. The mixed pain group showed significant differences compared with the JP group or MP group in neck disability (p < 0.001, d = 1.99; and p < 0.001, d = 1.17), craniomandibular pain and disability (p < 0.001, d = 1.34; and p < 0.001, d = 0.9, respectively), and impact of headache (p < 0.001, d = 1.91; and p < 0.001, d = 0.91, respectively). In addition, significant differences were observed between JP group and MP group for impact of headache (p < 0.001, d = 1.08). Neck disability was a significant covariate (37 % of variance) of craniomandibular pain and disability for the MP group (β = 0.62; p < 0.001). In the mixed chronic pain group, neck disability (β = 0.40; p < 0.001) and kinesiophobia (β = 0.30; p = 0.03) were significant covariate (33 % of variance) of craniomandibular pain and disability. Conclusion Mixed chronic pain patients show greater craniomandibular and neck disability than patients diagnosed with chronic JP or MP. Neck disability predicted the variance of craniofacial pain and disability for patients with MP. Neck disability and kinesiophobia predicted the variance of craniofacial pain and disability for those with chronic mixed pain.

Abstract
Joint Hypermobility Syndrome, also known as Ehlers-Danlos Syndrome Hypermobility Type (JHS/EDS-HT), is a heritable disorder of connective tissue, common but poorly known by the medical community. Although generalized joint hypermobility and fragility of tissues have been described as core features, recent research highlights the multisystemic nature of JHS/EDS-HT, which presents with a wide range of articular and extra-articular symptoms. Among these, gastrointestinal problems, temporomandibular disorders, and smell and taste abnormalities are common among those affected, having significant implications for eating. The present work reviews the literature linking JHS/EDS-HT and eating problems. Two illustrative case reports, in which JHS/EDS-HT manifestations contribute to developing and maintaining disturbed eating behaviors and significant weight loss, are presented.

Abstract
INTRODUCTION Temporomandibular disorders (TMD) and eating disorders (ED) affect function and parafunction of the oral cavity and have high rates of medical and psychological comorbidity. However, little is known about the possible associations between them, and few studies have investigated the existence of such associations. METHODS A search was conducted on the SciELO, LILACS, and PubMed/MEDLINE databases to find relevant articles written in English and Portuguese. Only studies involving human beings were included, and there was no limit for year of publication. RESULTS AND CONCLUSIONS There is evidence of the correlation between TMD and ED, but their comorbidity must be better understood. The presence of depressive symptoms is an aggravating factor that must also be taken into account during the diagnosis and treatment of those patients.

Abstract
Background Chronic temporomandibular disorder (TMD) is known to have strong correlations with psychological factors and to display gender disparity. However, while chronic TMD is known to affect quality of life, large-scale studies investigating the influence on quality of life by gender are scarce. Methods This cross-sectional study assessed the data of 17,198 participants aged ≥19 years who completed chronic TMD and EuroQol-5 Dimension sections in the 4th Korean National Health and Nutrition Examination Survey (2007–2009). We adjusted for covariates (health behavior, sociodemographic factors) in regression analysis for complex sampling design to calculate regression coefficients and 95% CIs for gender difference in the association between chronic TMD and quality of life. We also evaluated which covariates of somatic health, mental health, health behavior, and sociodemographic factors weakened the relationship between TMD and EQ-5D. Results Prevalence of chronic TMD was 1.6% (men 1.3%, women 1.8%), and chronic TMD persisted to negatively impact quality of life even after adjusting for confounding variables. Low sociodemographic factors and health behavior had a negative effect on quality of life. Somatic health and mental health were most affected by chronic TMD. As for quality of life, women were affected to a greater extent than men by TMD. Women were more affected by osteoarthritis and general mental health (stress, depressive symptoms, and thoughts of suicide), and men by employment. Conclusions These results imply that chronic diseases and psychological factors are important in chronic TMD, and that there may be physiological and pathological gender differences in TMD.

Abstract
PURPOSE The prevalence of temporomandibular disorders (TMD) in the general Polish population has not yet been thoroughly investigated. The aim of this study was to determine how frequently Polish young adults demonstrated the signs and symptoms of TMD, and how often they were aware of these. MATERIALS AND METHODS The study involved 260 volunteers of approximately 18 years of age (and with an F:M ratio of 2.8), who had completed the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire in its internationally accepted Polish version. The volunteers were students from three randomly selected high schools in Kraków, Poland. Following the clinical examinations, all participants received none or one or more of the RDC/TMD axis I diagnoses on one or both sides: muscle disorders (group I), disk displacements (group II), arthralgia, osteoarthritis, and osteoarthrosis (group III). Classification on RDC/TMD axis II involved pain-related impairment (Graded Chronic Pain Severity, from 0: no TMD pain in the prior 6 months, to IV: high disability-severely limiting), depression, and somatization levels (normal, moderate, severe). RESULTS On the RDC/TMD axis I, 69 (26.5%) of the participants received one or more of the possible diagnoses. Awareness of TMD was present in 20 (7.7%) people from that group, in the form of self-complaints. The difference between females and males was statistically significant (p = 0.0013). On the RDC/TMD axis II assessment, a diagnosis of pain, depression, or somatization was given in 38 (14.6%) cases from that group. CONCLUSION Muscle disorders were most frequently diagnosed in the group of Polish young adults, and the prevalence of the disease did not differ across similar groups of young people.

Abstract
The aim of the present study was to perform a systematic review of the literature on the
effects of low-level laser therapy in the treatment of TMD, and to analyze the use of
different assessment tools. [Subjects and Methods] Searches were carried out of the
BIREME, MEDLINE, PubMed and SciELO electronic databases by two independent researchers for
papers published in English and Portuguese using the terms: “temporomandibular joint laser
therapy” and “TMJ laser treatment”. [Results] Following the application of the eligibility
criteria, 11 papers were selected for in-depth analysis. The papers analyzed exhibited
considerable methodological differences, especially with regard to the number of sessions,
anatomic site and duration of low-level laser therapy irradiation, as well as irradiation
parameters, diagnostic criteria and assessment tools. [Conclusion] Further studies are
needed, especially randomized clinical trials, to establish the exact dose and ideal
parameters for low-level laser therapy and define the best assessment tools in this
promising field of research that may benefit individuals with signs and symptoms of
TMD.

Abstract
UNLABELLED [Purpose] The aim of the present study was to assess the behavior of the mean and median frequencies of the electromyography signal of the mastication muscles of adolescents with different degrees of TMD severity. [Subjects] Forty-two adolescents aged 14 to 18 years. [Methods] The adolescents were classified according to severity using the Helkimo Index. The control group consisted of 14 subjects with no signs or symptoms of TMD. Three readings were taken in during maximum intercuspation and mandibular rest, with each reading lasting 10 seconds. [Results] Significant differences (p=0.0001) were found in the mean frequency (Hz) between the control group (CG), mild TMD group (MG) and moderate/severe TMD group (MSG), especially during mandibular rest, for all muscles evaluated: right temporal: CG (137.5), MG (194.2), MSG (291.7); left temporal: CG (106.9), MG (200.6), MSG (294.2); right masseter: CG (155.7), MG (242.8), MSG (278.3); left masseter: CG (125.0), MG (214.6), MSG (316.7). Greater differences among groups were found under the condition of mandibular rest. CONCLUSIONS Adolescents with TMD especially those with more severe symptoms exhibit hyperactivity of the mastication muscles.

Abstract
AIM The aim of this study was to define the prevalence and severity of temporomandibular disorders (TMD) among Iranian dental and nondental students who attended Shiraz University of Medical Sciences. MATERIALS AND METHODS The samples consisted of 200 subjects, 100 dental and 100 nondental students (equal distribution between males and females). Subjects ages ranged from 18 to 30 years (24.07 ± 2.93). A functional evaluation was performed using the Helkimo dysfunction index (Di). Data were evaluated by the Chi-square test. RESULTS Among the total study population, 71% showed some degree of dysfunction. Prevalence ratio in dental students was 80%, while in nondental students was 62% (p > 0.05, odds ratio = 0.679). With respect to gender, women (80%) were more affected than men (62%). A significant relationship was found between gender and the occurrence of TMD (p > 0.05). CONCLUSION A high prevalence of signs of TMD in Iranian university students was seen which was greater in dental students and women. CLINICAL SIGNIFICANCE The results of this study showed that the prevalence of TMD among dental students and women was significantly higher than nondental students and men. These findings might be due to poor postural style or emotional stress during dental practice.
