Distribution of depression, somatization and pain-related impairment in patients with chronic temporomandibular disorders

Abstract Objective the aim of this study was to describe the frequency of psychosocial diagnoses in a large sample of patients attending a tertiary clinic for treatment of temporomandibular disorders (TMD). Material and Methods six hundred and ninety-one patients who sought treatment for pain-related TMD were selected. Chronic pain-related disability (Graded Chronic Pain Scale, GCPS), depression [Symptoms Checklist-90 (SCL-90) scale for depression, DEP] and somatization levels (SCL-90 scale for non-specific physical symptoms, SOM) were evaluated through the Research Diagnostic Criteria for TMD (RDC/TMD) Axis II psychosocial assessment; TMD diagnoses were based on the Axis I criteria. Results the majority of patients presented a low disability or no disability at all, with only a small portion of individuals showing a severely limiting, high disability pain-related impairment (4.3%). On the other hand, abnormal scores of depression and somatization were high, with almost half of the individuals having moderate-to-severe levels of depression and three-fourths presenting moderate-to-severe levels of somatization. The prevalence of high pain-related disability (GCPS grades III or IV), severe/moderate depression and somatization was 14.3%, 44% and 74.1% respectively. Gender differences in scores of SCL-DEP (p=0.031) and SCL-SOM (p=0.001) scales were signficant, with females presenting the highest percentage of abnormal values. Conclusion patients with TMD frequently present an emotional profile with low disability, high intensity pain-related impairment, and high to moderate levels of somatization and depression. Therefore, given the importance of psychosocial issues at the prognostic level, it is recommended that clinical trials on TMD treatment include an evaluation of patients' psychosocial profiles.

Prevalence and environmental impact factors of somatization tendencies in eastern Chinese adolescents: a multicenter observational study / Prevalência e fatores ambientais de tendências de somatização em adolescentes do leste chinês: um estudo observacional multicêntrico / Prevalencia y factores de impacto ambientales en las tendencias somatización con adolescentes de la China oriental: un estudio observacional multicéntrico

The aim of this study is at examining the prevalence and impact factors of adolescent somatization tendencies (ST) across three eastern Chinese provinces. A multicenter school-based cross-sectional study was conducted in these provinces from 2015 to 2016. The sample included 11,153 middle-school students aged 13-18 years, who were randomly selected using a multi-phase stratified cluster sampling technique. We also designed a multicenter school-based case-control study to evaluate the potential environmental impact of ST factors on this population. The overall positive rate of ST among the eastern Chinese adolescents was 12.1%. Somatic symptoms score (SSS) and positive ST rate were higher in females than males. Additionally, the SSS and positive ST rate for the 18-year-old group were significantly higher than in other age groups. In comparison to those in urban areas, adolescents in rural areas had significantly higher SSS and positive ST rate. Multiple conditional regression analyses revealed that family medical history, anxiety and depression scores; superstitious beliefs; left-behind adolescents; teacher-student support; family conflict; and family independence and achievement orientation were significantly linked to ST in adolescents. The models also indicated family medical history was the strongest impact factor to adolescent ST, even though ST were prevalent in the three studied eastern Chinese provinces. Gender, age, and dwelling differences were very significant in the SSS and positive ST rate in adolescents. This study concludes that adolescent ST are influenced by multiple environments.

O objetivo deste estudo é examinar a prevalência e fatores de impacto de tendências de somatização (TS) em adolescentes em três províncias do leste da China. Um estudo transversal multicêntrico baseado em escolas foi realizado nessas províncias de 2015 a 2016. A amostra incluiu 11.153 estudantes entre 13 e 18 anos que foram selecionados aleatoriamente usando uma técnica de amostragem estratificada por clusters multi-fase. Também elaboramos um estudo caso-controle multicêntrico baseado em escolas para avaliar o impacto ambiental potencial de fatores de TS nessa população. A taxa positiva geral de TS entre adolescentes do leste chinês foi de 12,1%. O escore de sintomas somáticos (SSS) e taxa positiva de TS foram mais altos entre mulheres do que homens. Adicionalmente, o SSS e taxa positiva de TS para o grupo de 18 anos foram significativamente mais altos do que em outros grupos etários. Em comparação com os habitantes de áreas urbanas, adolescentes de áreas rurais tiveram SSS e taxa positiva de ST significativamente mais altos. Análises de regressão múltipla condicional revelaram que o histórico de saúde da família; scores de ansiedade e depressão; crenças supersticiosas; adolescentes deixados para trás; apoio de professores a estudantes; conflito familiar; e independência familiar e orientação para sucesso estavam significativamente relacionadas a TS em adolescentes. O modelo também indicou que o histórico de saúde da família era o fator de impacto mais forte para TS em adolescentes, ainda que TS sejam prevalentes nas três províncias do leste da China estudadas. Gênero, idade e diferenças residenciais foram muito significativos para o SSS e taxa positiva de TS entre adolescentes. Este estudo conclui que TS entre adolescentes são influenciadas por múltiplos ambientes.

El objetivo de este estudio fue examinar la prevalencia y factores de impacto de las tendencias de somatización adolescentes (TS) en tres provincias orientales chinas. Se realizó un estudio trasversal multicéntrico, basado en escolares de estas provincias de 2015 a 2016. La muestra incluyó a 11.153 estudiantes de secundaria, con edades comprendidas entre los 13-18 años, que fueron seleccionados aleatoriamente, usando a técnicas de muestreo multifase estratificado por conglomerados. También se diseñó un estudio multicéntrico escolar de caso-control para evaluar el potencial impacto ambiental de factores TS en esta población. La tasa positiva general de TS entre adolescentes chinos orientales fue un 12,1%. El marcador de síntomas somáticos (SSS, por sus siglas en inglés) y tasa positiva de TS fueron más altos en mujeres que en hombres. Asimismo, las tasas SSS y TS positiva para el grupo de 18 años de edad fueron significativamente más altas que en otros grupos de edad. En comparación con quienes vivían en áreas urbanas, los adolescentes en áreas rurales contaban con tasas significativamente más altas de SSS y TS positivas. Los análisis de regresión múltiple condicional revelaron que el historial médico familiar, los marcadores de ansiedad y depresión; creencias supersticiosas; adolescentes a la zaga respecto al resto del grupo; el apoyo profesor-estudiante; conflictos familiares; e independencia familiar, así como la orientación de logros estuvieron vinculados a las TS en adolescentes. Los modelos también indicaron que el historial médico familiar fue el impacto más fuerte para las TS en adolescentes, a pesar de que las TS fueron prevalentes en las tres provincias chinas estudiadas. El género, edad, y las diferencias de vivienda fueron muy significativas en la tasas de SSS y TS positivas en adolescentes. Este estudio llega a la conclusión de que las TS adolescentes estaban influenciadas por múltiples entornos.

Dolor perdurable I. Nosología y epidemiología / [Enduring pain I. Nosology and epidemiology].

Pain disorders are extraordinarily prevalent throughout clinical medicine, and are highly co-morbid with various psychiatric disorders, particularly those including depression or anxiety. Assessment of such patients tends to be based on diagnostic criteria that may not reflect the complexity of the clinical problem and can result in prioritizing somatic aspects of painful syndromes at the expense of psychiatric aspects or, conversely, over-emphasize psychiatric aspects. In the first part of this overview we consider current nosological perspectives and their potential clinical consequences, epidemiological data that underscore the association of comorbid painful and affective or anxious syndromes, and consider the importance of psychiatric assessment and treatment of such patients. The major overlap between pain disorders and psychiatric disorders, as well as the unsatisfactory state of treatments available for chronic pain syndromes, encourage a comprehensive approach to assessing and clinically managing patients with chronic pain. Many programs for pain disorder patients offer narrowly specialized treatment options. To be preferred are multi-disciplinary teams with expertise in internal medicine, neurology, pain management, and rehabilitation, as well as psychology and psychiatry. In the second part of this overview, we propose that psychiatrists can serve a key role in leading comprehensive assessment and management of complex and challenging pain-psychiatric patients who are typically only partially responsive to available treatments.

Clustering of psychiatric and somatic illnesses in the general population: multimorbidity and socioeconomic correlates

The distribution of psychiatric disorders and of chronic medical illnesses was studied in a population-based sample to determine whether these conditions co-occur in the same individual. A representative sample (N = 1464) of adults living in households was assessed by the Composite International Diagnostic Interview, version 1.1, as part of the São Paulo Epidemiological Catchment Area Study. The association of sociodemographic variables and psychological symptoms regarding medical illness multimorbidity (8 lifetime somatic conditions) and psychiatric multimorbidity (15 lifetime psychiatric disorders) was determined by negative binomial regression. A total of 1785 chronic medical conditions and 1163 psychiatric conditions were detected in the population concentrated in 34.1 and 20 percent of respondents, respectively. Subjects reporting more psychiatric disorders had more medical illnesses. Characteristics such as age range (35-59 years, risk ratio (RR) = 1.3, and more than 60 years, RR = 1.7), being separated (RR = 1.2), being a student (protective effect, RR = 0.7), being of low educational level (RR = 1.2) and being psychologically distressed (RR = 1.1) were determinants of medical conditions. Age (35-59 years, RR = 1.2, and more than 60 years, RR = 0.5), being retired (RR = 2.5), and being psychologically distressed (females, RR = 1.5, and males, RR = 1.4) were determinants of psychiatric disorders. In conclusion, psychological distress and some sociodemographic features such as age, marital status, occupational status, educational level, and gender are associated with psychiatric and medical multimorbidity. The distribution of both types of morbidity suggests the need of integrating mental health into general clinical settings.

Factores asociados a síntomas depresivos y síntomas somáticos en mujeres climatéricas de la ciudad de Temuco / Associated factors to depressive symptoms and somatic symptoms in climacteric women in the city of Temuco

BACKGROUND: Depression is an important mental health problem. The Chilean Ministry of Health has considered depression in women as one of the health priorities for the country. AIM: To assess the prevalence of depressive and somatic symptoms and their risk factors in climacteric women. MATERIAL AND METHODS: A special questionnaire was applied to 171 women (45 to 55 years of age), coming from a community organization (PRODEMU) and a private health institution (ISAPRE Banmedica). Risk factors for depression were determined using multiple logistic regression. RESULTS: The prevalence of depressive symptoms was 43 per cent. Women with primary education had an odds ratio for depression of 2.49, compared with women with high school or university education. Other risk factor for depression was the lack of a renumerated job (Odds ratio 1.9). The risk factors for somatic symptoms were the presence of depressive symptoms (OR 3.2), lack of secondary or university education (OR 2.4), low income (OR 1.9) and having a current partner (OR 3.6). CONCLUSIONS: There is a high prevalence of depressive symptoms in the studied population of climacteric women. Lack of education and of a renumerated job are important risk factors for the presence of such symptoms. Women with a low level of education and with depressive symptoms have also a high risk of presenting somatic symptoms.

Comorbilidad de enfermedades médicas crónicas y transtornos psiquiátricos en una población de consultantes en el nivel primario de atención / Association of chronic diseases and psychiatric disorders among patients attending public primary care clinics

Background: As a part of the World Health Organization multicentric study of emotional disorders in general medical care, we studied patients who had a chronic medical ailment and a psychiatric disorder, according to ICD-10. Aim: To report the prevalence of patients with coexisting medical and psychiatric disorders. Patients and methods: All patients, aged 15 to 65 years old, consulting in primary care outpatient clinics, were interviewed using a general health questionnaire. In a second phase, patients with chronic medical disorders were subjected to the World Health Organization Composite International Diagnostic Instrument. Results: Sixty nine percent of interviewed Chilean patients had a medical condition, compared to 60,3 percent of the global study group. Of these, 66 percent had a coexisting psychiatric diagnosis, compared to 31 percent of the global study group. The most frequent diagnoses in the Chilean sample were somatization disorders in 25 percent, harmful alcohol use in 14 percent, depression in 35 percent and hypocondriasis in 6 percent. There was a higher prevalence and odds ratio for psychiatric diagnoses among Chilean women. Conclusions: Patients with chronic medical disorders should be considered a high risk group for the coexistence of psychiatric disturbances
