Prevalence and Factors Associated With Depression among School Going Adolescents in Bengaluru: A Cross-Sectional Study

Introduction: The period of adolescence involves a lot of emotional changes as it is a period of transition to adulthood demanding independence.Adolescents with depression are more likely to have anxiety, disruptive behavior disorder and substance abuse when compared to those who are not depressed. Objective: To estimate the prevalence of depression among school going adolescents and to assess the factors associated with depression among them. Method: A cross-sectional study was conducted among school going adolescents aged 13-16 years in the urban field practice area of a Medical College. Depression was assessed using Beck's depression inventory (BDI). Total 896 adolescents were included in this study. Single stage cluster sampling method was done in which schools were considered as clusters and students constituted the sampling units. Schools were selected by simple random sampling technique using lottery method. Results: In this study about 45.2% of the adolescents had depressive disorder, out of which mild depression was reported among 22.2% students, 12.4% moderately depressed and 10.6% severe depression. Factors like mother's education, lack of communication by father and mother with their children, lack of needs satisfied by the fathers of the adolescents (61.9%), father's role in adolescents' life (62%) and domestic violence in family (69.7%) were some of the important reasons for developing depression among adolescents. Adolescent whose parents were having conflict (69.2%) were found be depressed when compared to those adolescents whose parents had no conflicts this difference was statistically significant (p<0.05). Conclusion: The prevalence of depression was found to be 45.2%. Finding of the study emphasizes the need for creating awareness about the early identification of behavioral changes leading to depression among adolescents by the parents and teachers. It is also important to emphasize to the parents on how their relationship and behavior towards the family affects the mental wellbeing of the adolescents.

Depression Among PLHIV On ART, Attending Drop-In Centre Run by Positive People Network: A Cross Sectional Study in Surat, India

Background: PLHIV often suffer from depression and anxiety during their quest to adjust to the diagno-sis and face the difficulties of living with a chronic illness, of which permanent cure is yet to be discov-ered. Positive people network linkages should be established by each ART centre for its respective locali-ty. The objective of the study is to assess depression among HIV positive beneficiaries registered with Network of Surat People Living with HIV (NSP+) in Surat. Methods: A cross sectional study was conducted among 30 PLHIV on ART from Network of Surat People Living with HIV (NSP+). Beck Depression Inventory was applied to assess depression. Results: The mean BDI score among male and female participants was 25.6 (± 11.39) and 23 (± 12) re-spectively, 9 male participants were having moderate depression, 3 as severe, and 2 as extreme depres-sion. Among females 4 participants were found to having mild mood disturbance while 4 were classified as having moderate depression, whereas only 1 participant was classified as having extreme depression (score of 53). Pearson’s correlation between CD4 count and BDI score was found to be -0.35. Conclusion: Though majority of the participants are in WHO clinical stage 1, yet all the participants had borderline to extreme depression. Males had lower CD4 count, higher proportion of OI and higher mean score of BDI. Lower the CD4 count higher the severity of depression.

Prevalence of depression and associated factors among undergraduate medical students

Background: Depression has become one of the commonest mental ailments in current era. Its impact is far more in medical personnel than general population. Most of the medical students leave their houses for the first time and enter into the new environment of knowledge and responsibility. Though various studies have reported high prevalence of depression among undergraduate students, it was desirable to know its status in south Rajasthan. Methodology: A cross sectional study was conducted on 302 undergraduate medical students to know prevalence and risk factors for depression. Along with the pre-designed questionnaire, Beck Depression Inventory (BDI) Scale was used as study tools. Cut off value of 17 and above was considered to define the depression on BDI scale. Results: Prevalence of depression was 10% among undergraduate medical students. Statistically, female gender and students studying in fifth semester were significant risk factors. Residence, socio-economic class and family history of depression were not significant associated factors. Conclusion: Prevalence of depression is higher among medical undergraduates as compared to general population with female gender and fifth semester students being important risk factors

Functional somatic symptoms in patients with major depressive disorder in a tertiary care hospital

Background: Functional somatic symtpoms are common in patients with major depressive disorder. The aim of the research was to study the prevalence and typology of Functional Somatic Symptoms (FSS) in patients with depression. Methodology: A total of 50 patients participated in the study. They were assessed on Bradford Somatic Symptom inventory for Functional Somatic Symptoms (FSS), Beck Depression Inventory (BDI) for severity of depression, and Comprehensive Psychopathological Rating Scale? anxiety index (CPRS?AI) for anxiety symptoms. Results: The mean age of the study sample was 41.36 years (SD?12.79). Gender distribution was gender distribution (male ? 60% vs. females 40%). Majority of the symptoms were found in married (84%), Hindus (92%), and from nuclear family (58%). A more than half of the patients were from urban background (76%). The mean duration of illness at the time of assessment was 36 months. As per BDI severity score 36% have mild, 38% have moderate and 26% have severe depression. Total mean CPRS-AI is (8.78±4.46).The more common FSS as assessed on Bradford Somatic Inventory were severe headache (88%), feeling tired when not working (86%), lack of energy (weakness) much of the time (84%), pain in legs (82%), aches and pains all over the body (72%), mouth or throat getting dry (72%), head feeling heavy (70%), head feeling hot or burning (68%), pain or tension in neck and shoulder (66%), low back trouble (66%) and sweating a lot (64%). The prevalence and typology of FSS was to a certain extent influenced by the sociodemographic variables and severity of depression. Conclusion: Functional somatic symptoms are highly prevalent in depressed patients and hence deserve more attention while diagnosing depression

Reliability and validity of self-rated Family Burden Scale in families of the patients with anorexia nervosa / 上海交通大学学报（医学版）

Objective • To explore the reliability and validity of self-rated Family Burden Scale (FBS) evaluating caregiver burden in families of the patients with anorexia nervosa (AN). Methods • The study included female AN patients (n=103) treated in the Eating Disorder Center of Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine from Jul. 2017 to Jul. 2019 and their caregivers (parents, n=148). General demographic information of the patients and their caregivers, the course of illness and body mass index (BMI) of patients, and the time each caregiver spent in caring for the patient per day were recorded. FBS, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and the MOS item short form health survey (SF-36) were self-rated by the caregivers. One-third of the caregivers were selected by random number method for FBS rating by specialists. The reliability of the scale was evaluated by calculating Cronbach's α coefficient, self-rating and other-rating consistency and the consistency between husband and wife (41 couples). The validity of the scale was evaluated by calculating the correlation of FBS score with the course of disease, patients' BMI, the time spent in caring per day, scores of BAI and BDI, and vitality, social function, role-emotion and mental health domain of SF-36. Results • The Cronbach's α coefficient of FBS was 0.921, the correlation coefficient between self-rating and other-rating by specialists was 0.705 (P=0.000), and the correlation coefficient of consistency score between couples was 0.547 (P=0.000). FBS score showed no correlation with the course of disease, %BMI and the time spent in caring per day. Scores of BAI and BDI, and vitality, social function, role-emotion and mental health domain of SF-36 showed low correlation with FBS score (all P<0.05). Conclusion • Self-rated FBS shows good reliability when used in families of AN patients. The validity is not as ideal, which suggests further revision of the scale.

Sensitivity & Specificity Of Screening Tools For Postpartum Depression: A Systematic Review

@#Postpartum depression is a depressive episode that can start at any point during the first year after childbirth. There are several tools that can be used for PPD screening. The need to define a predictive tool that is clinically useful and has acceptable sensitivity and sensitivity is important especially to be used in the primary care setting. This systematic review investigates the evidence of the sensitivity and specificity of screening tools used for PPD screening. The Standard for Reporting of Diagnostic Accuracies (STARD) guidelines were used to conduct the review as a basis for our methodology. PubMed, ScienceDirect and Springerlink databases between 2007 until 2017 were comprehensively searched EPDS and BDI instrument has sensitivity of more than 80% but findings for specificity was inconclusive. The heterogeneity across studies could be the result of methodological differences in validation of the instruments. In addition, these studies were conducted across continents and settings with different cultures, languages and resources. We have identified 5 different instruments used to screen for postpartum depression. The EPDS was the most validated instrument in the review and we found that EPDS and BDI have higher accuracy to screen postpartum depression because the sensitivity reported were more than 80%.

The Effect of Knee Joint Traction Therapy on Pain, Physical Function, and Depression in Patients with Degenerative Arthritis

PURPOSE: To identify the effect of knee joint traction therapy on pain, physical function, and depression in patients with degenerative arthritis.METHODS: In total, 30 patients with degenerative arthritis were randomly assigned to one of two groups: the experimental group, who underwent knee joint traction therapy, and the control group, who underwent general physical therapy (15 patients per group). Pain was measured using the visual analogue scale (VAS), physical function was measured using the Western ontario and McMaster universities osteoarthritis (WOMAC) index, and depression was measured using the Beck depression inventory (BDI). The VAS, WOMAC score, and BDI score were recorded before and after the 4-week treatment.RESULTS: As a result of comparison within groups, the experimental and control group showed significant difference for VAS, WOMAC and BDI after the experiment (p<0.05). In comparison between the two groups, the experimental group in which knee joint traction was applied showed more significant change in VAS, WOMAC and BDI than the control group (p<0.05).CONCLUSION: This study showed that knee joint traction therapy was effective in improving pain, physical function, and depression in patients with degenerative arthritis.

Assessment of health-related quality of life (HRQoL) in patients with spasmodic dysphonia

Background: There is paucity of literature regarding health related quality of life in Spasmodic Dysphonia (SD) especially from India. This study assessed HRQoL in it’s global and disease specific aspect by previously validated instruments in patients with SD.Methods: The study was performed in AIIMS, New Delhi. Subjects with SD as well as age and gender matched healthy controls were enrolled from Movement Disorder and botulinum toxin clinic, Department of Neurology, AIIMS, New Delhi. Uneducated patient, those could not read questionnaires & cases who had received botulinum toxin within 6 months were excluded from the study. Each patient filled SF-36, BDI, VoiSS-30 and VPQ questionnaire.Results: 14 pts of Spasmodic Dysphonia (SD) were enrolled. Compared with controls SD patients suffered from statistically significant impaired global health related quality of life (SF36) in areas of role physical (p = 0.007), general health (p = 0.004), social functioning (p = 0.024), role emotion (p = 0.008) and mental health (p=0.039). Patients with SD scored much worse in BDI scale than their control group (12.57±8.0 vs. 4.71±5.0, p=0.005). 65% pt of SD had depression out of whom 14% had moderate depression. SD patient group showed statistically significant impaired scores in disease-specific QOL (VoISS) in 2 out of 3 subscales, impairment (p= <0.001) and emotional (p=<.001) but not in physical (p=0.44). Voice quality of patients with SD was severely affected compared to controls (mean 37± 8.0 vs. 12.9± 1.5).Conclusions: This study clearly demonstrated that patients with SD suffered from significant impairment in HRQoL as compared to controls. Higher proportion of patients with SD suffered from mild to moderate depression compared to their control.

Inventário de Depressão de Beck II: análises pela teoria do traço latente / Beck Depression Inventory II: analyses by latent trace theory / Inventario de Depresión de Beck II: análisis por la teoría del trazo latente

Este estudo tem o objetivo de avaliar as propriedades psicométricas do Inventário de Depressão de Beck ­ Segunda Versão (BDI-II), que visa avaliar a gravidade dos sintomas depressivos. A amostra contou com 2.385 participantes (13 a 85 anos) da região metropolitana de Porto Alegre, Rio Grande do Sul. Os seguintes métodos da Teoria do Traço Latente foram utilizados: Modelagem de Equação Estrutural Exploratória, Análise de Classe Latente e Análise Fatorial Confirmatória Multigrupo. Observou-se a possibilidade de que o BDI-II possa ser um instrumento unidimensional com subfatores mais restritos (modelo bifator). Encontrou-se evidências de que o instrumento apresente precisão de medida para a mensuração da gravidade dos sintomas depressivos. Também, pontos de corte foram sugeridos, verificando a possibilidade de três classes em termos de gravidade dos sintomas depressivos: mínimos, leves e moderados/graves. Dentre as limitações deste estudo, destaca-se que não foi efetuada a comparação com outras amostras com características diferenciadas. (AU)

This study aims to evaluate psychometric properties of the Beck Depression Inventory - Second Version (BDI-II), which aims to evaluate the severity of depressive symptoms. The following methods of the Latent Trace Theory were used: Exploratory Structural Equation Modeling, Latent Class Analysis and Multi-group Confirmatory Factor Analysis. The possibility that BDI-II could be a one-dimensional instrument with more restricted subfactors (bi-factor model) was observed. There was evidence that the instrument presented precision in measuring the severity of depressive symptoms. Cutoff points were also suggested, verifying the possibility of three classes in terms of depressive symptoms severity: minimal, mild, and moderate/severe. Among the limitations of this study, it should be noted that the comparison with other samples with different characteristics was not performed. (AU)

Propiedades psicométricas del modelo bifactorial del BDI-II (versión española) en muestras mexicanas de población general y estudiantes universitarios / Psychometric Properties of the BDI-II Bifactorial Model on Mexican General Population and University Students

En este trabajo, se analizan las propiedades psicométricas de la versión española (Sanz, Navarro, & Vázquez, 2003) del Inventario para la Depresión de Beck ([BDI-II]; Beck, Steer, & Brown, 1996) en muestras mexicanas no clínicas: 474 estudiantes universitarios y 478 personas de población general. La consistencia interna resultó satisfactoria en ambas muestras siendo alfa de Cronbach 0.901 para la muestra total. Los resultados coinciden con los reportados en estudios previos españoles (Sanz, Navarro & Vázquez, 2003; Sanz, Perdigón & Vazquez, 2003) acerca de las propiedades psicométricas del instrumento, así como otros estudios internacionales revisados. El análisis factorial confirmatorio muestra buenos índices de ajuste al modelo bifactorial de la escala. Se encontraron diferencias significativas en las puntuaciones en función del sexo, pero no se observan efectos significativos de la edad. Se concluye que la versión española del BDI-II puede ser un instrumento válido y fiable para evaluar la sintomatología depresiva en la población general adulta mexicana y en estudiantes universitarios.

The purpose of this study was to test the Spanish version (Sanz, Navarro, & Vazquez, 2003) of the Beck Depression Inventory-II ([BDI-II]; Beck, Steer, & Brown, 1996) in the Mexican general population and undergraduate university students on non clinical samples. The reliability and construct validity obtained in a sample of 474 university students and 478 people from the general population, confirmed good psychometric properties: Cronbach alpha of 0.901 and Confirmatory factor analysis, showed good adjustment indices to two-factor model scale. These results agree with those reported in previous studies both international and Spanish studies on the psychometric properties of the instrument (Sanz, Navarro, & Vázquez, 2003; Sanz, Perdigón & Vázquez, 2003). Confirmatory factor analysis showed a good fit of the Mexican population data, the two-factor model reported in the Spanish population. Finally, the distributions of scores were similar to those found in Spanish studies. There were significant differences in scores by gender, but there are no significant effects of age. It is concluded that the Spanish version of the BDI-II may be a valid and reliable instrument to assess depressive symptoms in college students and the general population of Mexican adults.

Impacts of Danhong Injection on Physiological and Biochemical Indicators in Mice / 医药导报

Objective To explore the impacts of Danhong injection on physiological and biochemical indicators in malnourished mice at physiological low doses, evaluate its safety, and test the practical value of safety re-evaluation of Traditional Chinese Medicinal ( TCM) injections. Methods A total of 32 ICR mice during growth period were selected to set up corn deficient nutrition mice model. Mice were assigned into the normal control group (given 0. 9% saline), Danhong injection at low, medium and high dosages (0. 2, 0. 4 and 0. 6 mL) groups (n=8 in each group);Mice were administered with respective medications intraperitoneally for 7 consecutive days. Blood samples were taken and mice were executed on the 8th day. All 9 kinds of organ or tissue were obtained completely, to measure related physiological and serum biochemical parameters. The safety of Danhong injection was evaluated by using Benefit and Damage Index - General Score ( BDI-GS ) system. Results The Danhong injection showed only slight damages on major organs or tissues, the BDI values were all above 0. 85, and the GS values were all above 9. 0;BDI values for Danhong injection at different dosages were all above 1. 0 for spleen and pancreas, showing better replenishing and healthy effects, and the differences were of statistical significance compared with the normal control group (P<0. 05 or P<0. 01). Meanwhile, it exerted obviously hypoglycemic effect. Conclusion Danhong injection is of rather low risk under physiological dosages, and therefore is safe to use. The mal-nutrition model combined with the BDI-GS system may be developed as a novel approach for safety re-evaluation of TCM injection in clinic.

Exploring the Non-Linear Relationship between Alcohol Consumption and Depression in an Elderly Population in Gangneung: The Gangneung Health Study

PURPOSE: The purpose of this study was to examine a J-shaped relationship between alcohol consumption and depression among the elderly in South Korea. MATERIALS AND METHODS: Cross-section data were drawn from a community-based sample of individuals 60 years of age and older (n=1819). Respondents completed the Alcohol Use Disorders Intensification Test (AUDIT) and the Korean Beck Depression Inventory. Using a regression approach, the effect of alcohol consumption as a non-linear effect was assessed in relation to gender, marital status, exercise, smoking, age, education, and physical and mental health. RESULTS: AUDIT total score were found to exert linear and quadratic effects that were significantly associated with higher depression scores among sample respondents. The results lend support to a J-shaped relationship between alcohol use and depression, wherein abstainers and problem drinkers were at a higher risk of depression. CONCLUSION: This study confirms a J-shaped (i.e., curvilinear) relationship between alcohol consumption and depression among elderly South Koreans, similar to that frequently found in studies of Western-based samples. The findings of this study, therefore, imply the applicability of the J-shaped relationship hypothesis for non-Western society samples and within different cultural contexts.

Sintomas depressivos em familiares de dependentes químicos / Depressive symptoms in family members of drug-addicts / Síntomas depresivos en familiares de dependientes químicos

O objetivo deste estudo foi avaliar a sintomatologia depressiva em familiares de dependentes químicos e sua relação com variáveis sociodemográficas dos participantes. A amostra foi composta por 100 familiares de dependentes químicos, a maioria do sexo feminino. O estudo foi realizado em instituições de tratamento para dependentes químicos em João Pessoa/PB. Utilizaram-se um questionário sociodemográfico e o Beck Depression Inventory (BDI), e os dados foram analisados por meio de estatística descritiva e inferencial. Constatou-se um índice de 66% de sintomatologia depressiva, dos quais 35% possuíam sintomas leves, 27%, moderados, e 4%, graves. A escolaridade mostrou-se significativamente relacionada com a sintomatologia depressiva, e identificaram-se maiores médias nos participantes com baixa escolaridade. Esses resultados são importantes porque os familiares são pouco estudados e assistidos pelas políticas públicas de saúde, embora sejam considerados relevantes no tratamento e na inclusão social dos dependentes químicos.

The main goal of this research was to investigate the depressive symptomatology in family members of drug-addicts and its relationship with socio-demographic variables of participants. The sample was composed by family members of 100 drug addicts, most female. The study was held up in drug-addiction rehab centers in the city of João Pessoa/PB. A socio-demographic questionnaire and the Beck Depression Inventory (BDI) were used and the data were analyzed by means of inferential and descriptive statistics. A depressive symptomatology index of 66% was observed, 35% with mild symptoms, 27% moderate, and 4% severe. The level of education was significantly related to depressive symptoms, identifying higher averages in participants with low education. These results are important because the family is not well studied and assisted by public health policies, although they are considered relevant in the treatment and inclusion of drug addicts.

Are Diatom-based Indices from Europe Suitable for River Health assessment in China? A Case Study from Taizi River, Northeastern China.

Aims: Diatom-based indices are widely used for river health assessment. Many such indices were originally developed in European countries based on a specific taxa list of benthic diatoms. Thus, the transferability of these indices to other rivers and geographic locations has been questioned. Design, Place and Duration of Study: In this study, we sampled benthic diatoms in the Taizi River, a temperate river in northeastern China during May 2009 to evaluate the applicability of eight commonly used diatom-based indices for assessing the principal water quality gradient and relationship with different water chemical parameters. Methodology: Sensitivities of the eight indices were evaluated by applying the principle component analysis (PCA), the box-plot map and multiple comparisons of the Kruskal– Wallis nonparametric test (K-W test). Results: The results showed that all eight of the tested indices showed significant correlations with the principal contamination gradient of both nutrient enrichment and organic pollution. The contamination gradient was extracted through principal component analysis and the first three axes explained 40.19%, 18.72%, and 9.77% of the total variation, respectively. Conclusion: Our results confirmed that the diatom-based indices did not properly reflect the current Chinese surface water quality classes. However, these indices showed consistent trends with chemical parameters that reflected general water quality condition, such as electric conductivity (EC); organic pollution, as reflected by dissolved oxygen (DO) and chemical oxygen demand (COD) and nutrient enrichment, as reflected by total nitrogen (TN) and total phosphorus (TP). The results indicated that both BDI and SHE were the most suitable diatom-based indices among the eight tested indices, although SPI, DES and ROTT were also suitable for river health assessment in the Taizi River.

Estudio comparativo de dos escalas de depresión en relación al intento de suicidio en adolescentes no consultantes / Comparative study of two scales of depression in relating to suicide attempt in no consultant adolecents

Introduction: 80 percent of young people who attempt suicide and 90 percent of those who consume it have a history of psychiatric disorders. The more involved psychopathologies are the mood disorders, especially depression. Objective: Characterize the behavior of 2 depression scales applied to adolescents in relation to suicidal attempts. Method: Cross-sectional analytical study. 195 adolescents were surveyed in the "Liceo Nueva Zelandia' of Santa Juana (Sampling error = 0.0445) media random sampling provided by sex and grade, including the application of Beck's Depression Inventory (BDI), Child Depression Inventory (CDI) and a history of attempted suicide. X², T-Student, Mann-Whitney U, Spearman linear correlation and binary logistic regression were used. Results: When analyzing the mean scores obtained by both groups, both scales show significant differences statistically (p < 0.001). The scales present a strong to moderate linear correlation (p < 0.001). Only BDI is significant in the logistic regression model (p = 0.001). Discussion: Although these scales evaluated the depression construct similarly, the CDI would be redundant to associate it with the suicide attempt. It would be necessary to implement the factorial studies of the composition of the BDI to identify components associated with attempted suicide...

Introducción: El 80 por ciento de los jóvenes que intentan suicidarse y el 90 por ciento de quienes lo consuman tienen historia de desordenes psiquiátricos. Las psicopatologías más involucradas son los trastornos del ánimo, especialmente la Depresión. Objetivo: Caracterizar el comportamiento de 2 escalas para Depresión aplicada en adolescentes relacionado al intento de suicidio. Método: Estudio analítico de corte transversal. Se encuestó a 195 adolescentes del Liceo Nueva Zelandia de Santa Juana (Error de muestreo = 0,0445) mediante muestreo aleatorio proporcionado por sexo y curso, incluyendo Escala de Depresión de Beck (BDI), Cuestionario de Depresión Infantil (CDI) y antecedentes de intento de suicidio. Se utilizaron estadísticos descriptivos, X², T-student, U Mann-Whitney, correlación lineal de Spearman y Regresión logística binaria. Resultados: Al analizar los promedios de los puntajes obtenidos por los grupos intentadores y no intentadores en ambas escalas presentan diferencias estadísticamente significativas (p < 0,001). Las escalas presentan una correlación lineal moderada a fuerte (p < 0,001). Sólo la BDI es significativa en el modelo de regresión logística (p = 0,001). Discusión: Si bien ambas escalas evalúan el constructo de depresión de manera similar, la CDI sería redundante al asociarla al intento de suicidio. Sería necesario poner en práctica los estudios factoriales de la composición de la BDI para identificar los componentes asociados al intento de suicidio...

Reliability and Validity of the Korean Version of Beck Depression Inventory-II via the Internet : Results from a University Student Sample / 신경정신의학

OBJECTIVES: The purpose of this study was to evaluate the properties of the Beck Depression Inventory-II (BDI-2) via the internet. METHODS: Participants included 1967 students of a university. A confirmatory factor analysis was performed to test whether the factor structure of the BDI-2. Convergent validity was assessed by correlating the scores on the BDI-2 with those on other scales. RESULTS: Two-week test-retest reliability was high (r=0.84) and internal consistency was good (Cronbach's alpha=0.882). The BDI-2 showed a good criterion validity with strong correlation with Patient health questionnaire 9 (PHQ-9). Factor structure of the BDI-2 was established using the three-factor structure, which explained 43% of the total variance. CONCLUSION: The results of the current study indicate that the BDI-2 is an effective and valid scale for evaluation of depression among Korean university students. The findings suggest that the BDI-2 is a promising assessment tool for use in depression and study of depression via the internet.

The Prevalence and Characteristics of Depression in Work-related Musculoskeletal Disease

OBJECTIVE: To reveal the relationship between depression and WMSD. METHOD: Five physiatrists participated in the workplace musculoskeletal survey and diagnosed 724 office workers with WMSD by performing detailed history taking and physical examination. All subjects were asked to answer the Korean version of the Beck depressive inventory (K-BDI), and to express their pain according to the visual analogue scale (VAS) score. We categorized the subjects into 4 groups, myofascial pain syndrome (MPS), herniated intervertebral disk (HIVD), tenosynovitis, and others, and investigated the prevalence of depression in desk workers and relationship between WMSD and depression, and we compared pain intensity between the depression and non-depression groups. Correlation analysis was carried out between K-BDI and VAS scores in each group. RESULTS: The mean K-BDI score were 8.7+/-6.68. The prevalence of depression was higher in females than in male, and there was no relationship between age and depression. There was a significant connection between HIVD and depression (p<0.05). However, the other groups did not have significant connection to depression. The VAS score (5.02) of the depression group was significantly higher than that (4.10) of the non-depression group. In addition, there was a significant difference of VAS scores between the depression group and non-depression group in each disease group. CONCLUSION: The mean VAS score of the depression group in WMSD was significantly higher than in the non-depression group. The correlation between BDI and VAS scores in the subjects was present, and the highest was in the HIVD group.

Patterns of depressive symptoms among patients with HIV infection / Patrones de síntomas depresivos entre pacientes con infección por VIH

OBJECTIVE: To identify the level of depressive symptoms among patients with HIV infection and to examine the reported patterns of depressive symptoms not confounded by the physical manifestations of HIV-infection. METHOD: A total of 191 patients with HIV infection (75 males (39%) and 116 females (61%), mean age 40.48 ± 10 years), from three HIV clinics were administered the Beck Depression Inventory - II as well as a demographic questionnaire as part of a larger study. RESULTS: Moderate to severe depressive symptoms were reported by 17.3% of the HIV-infected patients with females reporting significantly higher levels of depressive symptoms than males. A principal components analysis identified three clusters of depressive symptoms: cognitive-affective, negative cognitions and somatic symptoms. The HIV-infected patients were found to display mainly cognitive-affective symptoms of depression. CONCLUSION: HIV-infected patients, especially female patients, may be at an increased risk of experiencing high levels of depressive symptoms. It is recommended that HIV-infected patients be routinely screened for depression, particularly cognitive-affective symptoms of depression.
