Objective: To explore the relevant factors of work-related musculoskeletal disorders (WMSDs) among dentists through Meta analysis, providing a basis for the prevention and control of WMSDs among dentists. Methods: In April 2022, cross-sectional research literatures on the prevalence correlation of WMSDs among Chinese dentists were searched in databases such as China National Knowledge Infrastructure, Wanfang, VIP, PubMed, Web of Science, and Em Base database. The search was conducted from the establishment of the database until April 2022, literatures were selected using keywords such as musculoskeletal disorders and dentists. To extract gender, age, length of service, disease classification and other related influencing factors as indicator, and prevalence was selected as the outcome indicator. After evaluating the quality of the literatures, RevMan 5.3 software was used to calculate the combined RD (95%CI) values of the included literatures. Results: A total of 15 articles were included, with a total sample size of 3646 people. Meta analysis results showed that the prevalence of WMSDs among dentists in China was 80%, and the top three parts of the incidence rates were 65% of the waist, 58% of the neck, and 50% of the back. Gender, age, length of service, region and disease classification all increased the risk of WMSDs, and the combined effect size were 75%, 78%, 71%, 77% and 82% respectively (P<0.05) . Conclusion: The occurrence of WMSDs among dentists in China is related to multiple factors such as gender, age, length of service and disease classification. The above risk factors should be taken into account in the workplace and preventive measures should be actively implemented to prolong the working life of dentists.

Factors associated with musculoskeletal symptoms in professionals working in sitting position / Fatores associados a sintomas osteomusculares em profissionais que trabalham sentados

ABSTRACT OBJECTIVE To estimate the prevalence of musculoskeletal symptoms and analyze their associated factors in professionals from administrative sectors working predominantly in sitting position. METHODS This is a cross-sectional study with data obtained from 451 workers from a federal public institution in Southern Brazil. The dependent variable was the number of musculoskeletal symptoms in the prior 12 months, measured using the Nordic Musculoskeletal Questionnaire. In the analyses, 19 independent variables were investigated, divided into four categories: sociodemographic, behavioral, occupational and health characteristics. Univariate analysis and multiple Poisson regression with robust variance were performed. The independent variables were inserted into blocks with stepwise backward criterion, considering the value for Wald statistics equal to 0.20. The effect measures were expressed in a relative increase (RI) in the mean value, and the data were analyzed for a 5% significance level. RESULTS The estimated prevalence of musculoskeletal symptoms in the prior 12 months was 90% (confidence interval - 95%CI 87-93). In the final model of regression analysis, the variables female gender (RI = 14.75%), low (RI = 100.02%) and moderate (RI = 64.06%) work ability index, use of medications (RI = 48.06%) and waist circumference at risk (RI = 15.59%) had a significant association with the increase in the mean number of symptoms; schooling with technical education acted as a protective factor, reducing the mean by 36.46%. CONCLUSIONS The high prevalence of musculoskeletal symptoms found and the associated factors indicate the need to propose specific actions and care for this population, such as immediate treatment of symptoms and changes in the organization and work environment, to achieve balance and harmony in the demands of prolonged sitting work and avoid its impact effect of this condition on public health.

MÉTODOS Trata-se de estudo transversal com dados obtidos de 451 trabalhadores de instituição pública federal na região Sul do país. A variável dependente foi o número de sintomas osteomusculares nos últimos 12 meses, aferido utilizando-se o Questionário Nórdico de Sintomas Osteomusculares. Foram investigadas 19 variáveis independentes, divididas em quatro categorias: características sociodemográficas, comportamentais, ocupacionais e de saúde. Foi realizada análise univariada e, na sequência, regressão múltipla de Poisson com variância robusta. As variáveis independentes foram inseridas em blocos com critério backward stepwise, considerando o valor para estatística de Wald igual a 0,20. As medidas de efeito foram expressas em aumento relativo (AR) no valor médio, sendo os dados analisados para um nível de significância de 5%. RESULTADOS A prevalência estimada de sintomas osteomusculares nos últimos 12 meses foi de 90% (intervalo de confiança - IC95% 87-93). No modelo final da análise de regressão, as variáveis sexo feminino (AR = 14,75%), índice de capacidade para o trabalho baixo (AR = 100,02%) e moderado (AR = 64,06%), uso de medicamentos (AR = 48,06%) e circunferência da cintura em risco (AR = 15,59%) tiveram associação significativa com o aumento da média de sintomas; já a escolaridade com ensino técnico atuou como fator de proteção, reduzindo a média em 36,46%. CONCLUSÕES A alta prevalência de sintomas osteomusculares encontrada e os fatores associados indicam a necessidade de propor ações e cuidados específicos para essa população, como tratamento imediato dos sintomas e mudanças na organização e no ambiente laboral, a fim de alcançar equilíbrio e harmonia nas exigências do trabalho sentado prolongado e evitar o impacto dessa condição na saúde pública.

Musculoskeletal disorders, stress perception and physical activity in police officers / Desordens musculoesqueléticas, percepção de estresse e atividade física em policiais / Trastornos musculoesqueléticos, percepción del estrés y actividad física en agentes de policía

ABSTRACT The purpose of this study is to analyze association between stress perception and physical activity with the prevalence of symptoms of musculoskeletal disorders (SMSD) in police officers. The police officers (n=142) answered the Perceived Stress Scale-10 (PSS-10) and the Nordic Musculoskeletal Questionnaire. Pearson's linear correlation coefficient was used to measure strength and direction of relationship between PSS-10 and prevalence of SMSD and showed a positive correlation between variables in the last 7 days (r=0.34, p=0.00001) and in the last 12 months (r=0.40, p=0.00001). The mean prevalence of SMSD in the last 12 months was lower among police officers practicing physical activity (W=1888.5, p=0.04). Multiple logistic regression analysis showed that the practice of physical activities as well as efforts to reduce stress perception both decrease the odds of musculoskeletal disorders. This study indicated that stress level and physical activity practice influenced in prevalence of SMSD. Multidisciplinary interventions with actions to reduce stress level and encourage physical activity practice are needed to control SMSD prevalence.

RESUMO O objetivo deste estudo foi analisar a associação entre percepção de estresse e atividade física com a prevalência de sintomas de distúrbios musculoesqueléticos (SDM) em policiais. Os policiais (n=142) responderam à escala de estresse percebido-10 (EEP-10) e ao questionário nórdico-musculoesquelético. O coeficiente de correlação linear de Pearson foi utilizado para mensurar a força e o sentido da relação existente entre EEP-10 e a prevalência de SDM e mostrou que existe uma correlação positiva entre as variáveis nos últimos 7 dias (r=0,34, p=0,00001) e nos últimos 12 meses (r=0,40, p=0,00001). A prevalência média de SDM nos últimos 12 meses é menor entre os policiais que praticam atividade física (W=1888,5, p=0,04). A análise de regressão logística múltipla mostrou que a prática de atividades físicas e a diminuição na percepção do estresse reduzem a prevalência de SDM. Este estudo indicou que o nível de estresse e a prática de atividade física influenciaram a prevalência de SDM. Intervenções multidisciplinares com ações para reduzir o nível de estresse e encorajar a prática de atividade física são necessárias para controlar a prevalência de SDM.

RESUMEN El objetivo de este estudio fue analizar la asociación entre estrés percibido y actividad física con prevalencia de síntomas del trastorno musculoesquelético (STM) en los agentes de policía. Los oficiales de policía (n=142) respondieron la escala de estrés percibido-10 (EEP-10) y el Cuestionario nórdico-musculoesquelético. Coeficiente de correlación lineal de Pearson se utilizó para medir fuerza y dirección entre EEP-10 y prevalencia de STM y mostró que hubo una correlación positiva entre las variables últimos 7 días (r=0,34, p=0,00001) y últimos 12 meses (r=0,40, p=0,00001). La prevalencia promedio de STM en últimos 12 meses es menor entre los oficiales que realizan actividad física (W=1888,5, p=0,04). El análisis de regresión logística múltiple mostró que actividad física y disminución de percepción del estrés reducen prevalencia de STM. El presente estudio indicó que nivel de estrés y actividad física influyó en prevalencia de STM. Las intervenciones multidisciplinarias con acciones para reducir los niveles de estrés y fomentar la actividad física son necesarias para controlar la prevalencia de STM.

A painful symphony: the presence of overuse syndrome in professional classical musicians / Una sinfonía dolorosa: la presencia del síndrome de uso excesivo en músicos clásicos profesionales

Musculoskeletal problems are common in instrumental musicians. Little is known about the factors that place musicians at risk, and the ways in which musicians can prevent these problems. Overuse syndrome is the most reported diagnosis among instrumental musicians suffering from playing related musculoskeletal injuries. The study group comprised 50 musicians employed in Symphony Orchestra of the Serbian National Theatre of Novi Sad. Out of the 50 musicians, 30 (60 %) are male and 20 (40 %) female. Higher frequencies of the presence of musculoskeletal symptoms were neck, region of trapezius, back, shoulder, wrist, hand and arm. A larger number of musicians (81.8 %) had perception of high demand of the profession. This investigation with professional classical musicians should show the music-medical interest.

Los problemas musculo-esqueléticos son comunes en los músicos instrumentales. Poco se sabe sobre los factores que ponen en riesgo a los músicos y las formas en que los ellos pueden prevenir estos problemas. El síndrome de uso excesivo es el diagnóstico más informado entre los músicos instrumentales que sufren lesiones musculo-esqueléticas relacionadas al uso de instrumentos musicales. El grupo de estudio estuvo compuesto por 50 músicos de la Orquesta Sinfónica del Teatro Nacional Serbio de Novi Sad. De los 50 músicos, 30 (60 %) eran hombres y 20 (40 %) mujeres. La frecuencia más alta de presencia de síntomas musculoesqueléticos se produjo en el cuello, músculo trapecio, espalda, hombro, muñeca, mano y brazo. Un mayor número de músicos (81,8 %) tuvo una percepción de alta demanda de la profesión. Esta investigación con músicos clásicos profesionales debería ser de interés médico-musical.

Abstract This article aims to identify the factors associated with musculoskeletal disorders (MSDs) in the neck/shoulder and distal upper limb in artisanal fisher/shellfish gatherers in Saubara, Bahia, Brazil. This cross-sectional epidemiological study was conducted with shellfish gatherers. The Brazilian version of the Job Content Questionnaire (JCQ), the Nordic Musculoskeletal Questionnaire (NMQ), and a questionnaire containing physical demands adapted to the labour of shellfish gatherers were used in this study. Factor analysis was performed to aggregate the physical demands. Multivariate analyses were performed according to the risk factors for MSDs in the neck or shoulder and MSDs in the distal upper limb. For MSDs in the neck or shoulders, a prevalence ratio (PR) of 1.28 (95% confidence interval [95% CI]: 1.09-1.49) was found, according to the aggregate physical demands. For MSDs in the distal upper limb, the PRs were as follows: 1.26 (95% CI: 1.07-1.47) according to the daily hours devoted to work as shellfish gatherers, 0.74 (95% CI: 0.57-0.96) according to the development of other current work and 1.38 (95% CI: 1.05-1.83) according to the aggregate physical demands. The activities performed by shellfish gatherers contribute to the occurrence of MSDs.

Prevalence of musculoskeletal pain in dental students and associated factors

Aim: The objective of this research was to evaluate the prevalence of painful symptoms among dental academics, as well as their associated factors. Methods: A cross-sectional study was carried out at a public higher education institution, and the study population (n = 303) included undergraduate students who studied at least one subject that included clinical activities. For data collection, two self-administered questionnaires were delivered to the participants, the first of which consisted of sociodemographic variables, academic life, harmful habits, physical activity practice, and general health. The validated Nordic Musculoskeletal Questionnaire was used to identify musculoskeletal symptoms, the need to seek health resources, and to assess whether the disorders interfered with the work activities of academics. Results: The presence of pain in the past 12 months was observed in 199 participants (82.6%). Several variables, including gender, number of courses performed, physical activity, and general health status, had an association with painful symptoms in at least one area of the body (GA) over the past 12 months. In addition, variable general health was associated with pain symptoms in any area of the body (DG) over the past seven days. Conclusion: There was a high prevalence of musculoskeletal symptoms, especially in the upper limbs, and there were associations between muscular pain and the number of disciplines studied and between muscular pains and the general health of the students

Seven musculoskeletal pain syndromes were also evaluated: juvenile fibromyalgia, benign joint hypermobility syndrome, myofascial syndrome, tendinitis, bursitis, epicondylitis, and complex regional pain syndrome. Results: Inter-rater agreement between pretest and retest was 0.83. Musculoskeletal pain and musculoskeletal pain syndrome were found in 183/299 (61%) and 60/183 (33%), respectively. The median age (15 [10-18] vs. 14 [10-18] years, p = 0.032) and years of education (10 [5-12] vs. 9 [5-12] years, p = 0.011) were significantly higher in adolescents with musculoskeletal pain when compared with those without this condition. The frequencies of female gender (59% vs. 47%, p = 0.019), cell phone use (93% vs. 81%, p = 0.003), and simultaneous use of at least two electronic devices (80% vs. 67%, p = 0.011) were significantly higher in the former group. Further comparisons between adolescents with and without musculoskeletal pain syndromes revealed that the frequency of female gender was significantly higher in the former group (75% vs. 25%, p = 0.002), and with a significantly reduced median of weekends/holidays electronic games use (1.5 [0-10] vs. 3 [0-17] h/day, p = 0.006). Conclusions: A high prevalence of musculoskeletal pain/syndromes was observed in female adolescents. Musculoskeletal pain was mostly reported at a median age of 15 years, and students used at least two electronic devices. Reduced use of electronic games was associated with musculoskeletal pain syndromes.

Resumo Objetivo: Avaliar o uso de televisão e dispositivos eletrônicos em adolescentes com dor e síndromes musculoesqueléticas. Métodos: Foi feito um estudo transversal com 299 adolescentes saudáveis de uma escola particular. Todos os alunos responderam a um questionário autoaplicável, que incluiu perguntas sobre: dados demográficos, prática de atividade física, sintomas de dor musculoesquelética e o uso de televisão/dispositivos eletrônicos (computador, internet, jogos eletrônicos e celular). Sete síndromes musculoesqueléticas foram avaliadas: fibromialgia juvenil, síndrome de hipermobilidade articular benigna, síndrome miofascial, tendinite, bursite, epicondilite e síndrome de dor regional complexa. Resultados: A concordância entre o pré-teste e reteste foi de 0,83. Dor musculoesquelética e síndromes musculoesqueléticas foram encontradas em 183/299 (61%) e 60/183 (33%), respectivamente. As medianas de idade [15 (10-18) versus 14 (10-18) anos, p = 0,032] e de anos de escolaridade [10 (5-12) vs. 9 (5-12) anos, p = 0,010] foram significantemente maiores em adolescentes com dor musculoesquelética em comparação com aqueles sem essa condição. As frequências do sexo feminino (59% versus 47% p = 0,019), uso do telefone celular (93% contra 81%, p = 0,003) e do uso simultâneo de pelo menos dois dispositivos eletrônicos (80% vs. 67%, p = 0,011) foram significantemente maiores no grupo de adolescentes com dor musculoesquelética. Comparações adicionais entre os adolescentes com e sem síndromes musculoesqueléticas revelaram que a frequência do sexo feminino foi significantemente maior no primeiro grupo (75% versus 25%, p = 0,002) e com mediana significantemente reduzida de horas de jogos eletrônicos nos fins de semana e feriados [1,5 (0-10) vs. 3 (0-17) horas/dia, p = 0,006]. Conclusões: Uma alta prevalência de dor/síndromes musculoesqueléticas foi observada em adolescentes do sexo feminino. A dor musculoesquelética foi predominantemente relatada entre alunos com mediana de idade de 15 anos e que usavam pelo menos dois dispositivos eletrônicos simultaneamente. O uso reduzido de jogos eletrônicos foi associado à presença de síndromes musculoesqueléticas.

Prevalencia de síntomas músculo-esqueléticos de la mano en estudiantes de odontología / Prevalence of Musculoskeletal Symptoms of the Hand Among Dental Students

Resumen Introducción: Los síntomas músculo-esqueléticos de las extremidades superiores son comunes entre los trabajadores dentales debido a la exposición a factores de riesgo, como movimientos repetitivos, esfuerzos intensos de manos, y malas posturas de muñecas. A medida que los estudiantes de odontología aprenden nuevas habilidades y procedimientos durante la escuela, experimentan un aumento gradual a estos factores de riesgo. El propósito de este estudio fue determinar la prevalencia de los síntomas musculo-esqueléticos (SME) de mano y muñeca entre los estudiantes de odontología de la Universidad de Iowa. Métodos: A 35 estudiantes de primer año y 39 estudiantes de cuarto año (N = 74) se les pidió que llenaran dos cuestionarios. Resultados: La prevalencia de los SME moderados/severos de la mano dominante como entumecimiento, hormigueo y dolor entre los estudiantes de primer año fue de 0, 6 y 20%, respectivamente, comparado con el 18,15 y 36% de los estudiantes de cuarto año. Conclusiones: Los SME de la mano dominante fueron más comunes entre los estudiantes de odontología de cuarto año, en comparación con los de primer año.

Abstract Introduction: Musculoskeletal symptoms of the upper extremities are common among dental workers due to exposure to risk factors including repetition, forceful exertions of the hand, and awkward wrist postures. As dental students learn new skills and procedures during dental school, they experience a gradually increasing exposure to these risk factors. The purpose of this study was to determine the prevalence of hand and wrist musculoskeletal symptoms (MSS) among dental students of the University of Iowa. Methods: Thirty-five first year students and thirty-nine fourth year students (N=74) were asked to complete two questionnaires. Results: The prevalence of moderate/severe MSS of the dominant hand such as numbness, tingling and soreness among first year students was 0, 6 and 20% respectively compared to 18, 15 and 36% of the fourth year students. Conclusions: In this relatively small sample, MSS of the dominant hand were more common among fourth year dental students when compared to first year students.

Abstract Objective To assess the occurrence of an aggregate risk to cardiometabolic and musculoskeletal health of Brazilian adolescents in the period 2008/09 and 2013/14 and to identify whether there are differences in risk between the genders and in these periods. Methods This was a trend epidemiological study with a quantitative approach, consisting of a voluntary sample of adolescents from 16 Brazilian states. Data were extracted from the database of Brazil Sports Project (Projeto Esporte Brasil). Health-related physical fitness was evaluated based on body mass index, cardiorespiratory fitness, flexibility, and abdominal strength/resistance. Descriptive analysis, chi-squared test, and Poisson log regression were used for the statistical treatment. Results In the years 2008/09, 14.6% of Brazilian youngsters showed an aggregate risk to cardiometabolic health and 17.1% an aggregate risk for musculoskeletal indicators, whereas in 2013/14, the values of the risk indicators were, respectively 40.0% and 22.4%. It was observed that, in the years 2013/14, the risk to the cardiometabolic health of boys was 2.51 times greater than in 2008/09, while for girls, a three-fold increase in risk was observed. Concerning musculoskeletal health, girls showed a 2.21 risk of being in the risk zone in 2013/14 when compared with 2008/09. Conclusion The occurrence of an aggregate risk to the cardiometabolic and musculoskeletal health of Brazilian adolescents increased in the 2008/09 and 2013/14 periods. Regarding gender, an increase in the cardiometabolic and musculoskeletal risk between these periods was observed in girls. As for boys, an increase was observed only in cardiometabolic risk.

Public social security burden of musculoskeletal diseases in Brasil-Descriptive study

SUMMARY BACKGROUND: To present data on the social security burden of diseases of the musculoskeletal system and connective tissue (DSOTC) in Brasil in 2014, and evolution of these social security expenditures between 2009 and 2014. METHOD: Compilation and analysis of data on the granting of disability pensions and sickness benefits in the year 2014, available on the official website of Social Security, classified according to ICD 10. It was evaluated the evolution between 2009 and 2014, using the F test to compare the curves with the growth of the active age population (PIA). RESULTS: Among the 22 disease groups classified according to ICD-10, the DSOTC group led benefits grants in 2014, with 19% of the sickness benefits and 13.5% of the disability pensions. The main causes of sickness benefit and disability retirement were, respectively: dorsopathies (43.3% and 41.2%), soft tissue diseases (27.3% and 19.7%), osteoarthritis (7.6% % And 27.8%) and chronic inflammatory arthropathies (2.8% and 7.9%). In the evolution of the number of sickness benefits granted between 2009 and 2014, both INSS and DSOTC totals showed an increasing tendency (35.9 and 35.3%, respectively, with p = 0.000 for both). As for disability retirement, there was a 5.9% increase in the INSS total (p = 0.039), while for the DSOTC there was a decrease of 7.6% (p = 0.005). CONCLUSIONS: These data point to a progressive increase in the granting of sickness pensions and disability benefits in the country, superior to the growth of the PIA, as well as a high participation of DSOTC in these benefits.

RESUMO OBJETIVOS: Apresentar dados sobre o ônus previdenciário das doenças do sistema osteomuscular e tecido conjuntivo (DSOTC) no Brasil no ano de 2014, e sua evolução entre 2009 e 2014. MÉTODO: Compilação e análise de dados sobre a concessão de aposentadorias por invalidez e auxílios-doença no ano de 2014 disponíveis no portal oficial da Previdência Social, classificados segundo o CID 10. Avaliação da evolução entre 2009 e 2014, utilizando-se o teste F para comparar as curvas com o crescimento da população em idade ativa (PIA).

Absenteísmo por distúrbios musculoesqueléticos em trabalhadores do Brasil: milhares de dias de trabalho perdidos / Absenteeism due to musculoskeletal disorders in Brazilian workers: thousands days missed at work

RESUMO: Objetivo: Descrever e analisar o absenteísmo dos trabalhadores do Brasil notificados com distúrbios musculoesqueléticos, do período de 2007 a 2012. Métodos: Estudo quantitativo, transversal e descritivo, com dados retrospectivos e secundários. Os registros foram do Sistema de Informação de Agravos de Notificação, que notifica trabalhadores em regime de previdência, bem como os informais. O período do estudo foi de seis anos. As variáveis foram: sociodemográficas, organizacionais do trabalho e específicas do agravo. Resultados: Foram aproximadamente 5 milhões de dias perdidos de trabalho, de 18.611 trabalhadores afastados e notificados com o agravo. Os grupos que mais se destacaram na análise foram os analfabetos, na faixa etária dos 50 aos 59 anos, com carga horária diária de trabalho acima de 6 horas, do grande grupo ocupacional 4, os CID-10 M50 e M51 e os trabalhadores com transtornos mentais. Conclusões: Elevado absenteísmo entre os trabalhadores com distúrbios musculoesqueléticos, analfabetos, idade dos 50 aos 59 anos, trabalhadores de serviços administrativos, CID-10 M51 e trabalhadores com transtornos mentais. Há necessidade de traçar políticas públicas que contemplem o absenteísmo causado pelo agravo, a fim de reduzir a morbidade, bem como os prejuízos socioeconômicos.

ABSTRACT: Objective: To describe and analyze the absenteeism of Brazilian workers notified with musculoskeletal disorders, from 2007 to 2012. Methods: This is a quantitative, cross-sectional and descriptive study, including retrospective and secondary data. The records came from the Information System of Notifiable Diseases, which notifies workers on a social security system, as well as informal workers. The study lasted for six years. We analyzed sociodemographic, work organization and injury variables. Results: There were approximately 5 million working days lost for 18,611 workers who were notified and removed from the position. The groups that stood out in the analysis were the illiterate people, in the age group of 50 to 59 years, with daily working hours higher than 6 hours, from the great occupational group 4, the ICD-10 M50 and M51, and workers with mental disorders. Conclusions: High absenteeism among workers with musculoskeletal disorders, illiterate, aged from 50 to 59 years, administrative service workers, ICD-10 M51 and workers with mental disorders. It is necessary to outline public policies that contemplate the absenteeism caused by the disease, in order to reduce morbidity, as well as the socioeconomic losses.

Systemic diseases and other painful conditions in patients with temporomandibular disorders and migraine

Abstract Temporomandibular disorders (TMD) are a highly prevalent, painful musculoskeletal condition affecting the masticatory system, and are frequently associated with migraines (M) and other diseases. This study aimed to investigate the association between painful TMD and M with other painful conditions and systemic diseases, such as cervicalgia, body pain (BP), ear-nose-throat disorders, musculoskeletal disorders, diabetes, cardiopulmonary diseases and gastritis/peptic ulcer. Methods: This was a cross-sectional study conducted in a sample of 352 individuals. Participants were stratified into three groups according to the presence of painful TMD and M: controls [individuals free of TMD and any headache (HA)]; TMD only (presence of painful TMD, but free of any HA); and TMD+M (presence of painful TMD and M). TMD was classified according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) - Axis I. Nonspecific physical symptoms (NSPS) were assessed by RDC/TMD - Axis II. The International Classification of Headache Disorders - II criteria, second edition, were applied to identify and classify primary HA. Other painful conditions and systemic diseases were assessed by volunteers' self-report. The prevalence of all assessed conditions was higher in the TMD+M group. Multiple regression models showed that cervicalgia was associated with the TMD only group (p<0.05), whereas gender (p<0.05), cervicalgia (p<0.05), BP (p<0.05) and NSPS (p<0.05) were significantly associated with the TMD+M group. Our results suggest that individuals with a comorbidity (TMD associated with M) have a more severe condition than those presenting only painful TMD.

Musculoskeletal pain among school teachers are we underestimating its impact?

Background: Musculoskeletal disorders (MSDs) are a common occupational health condition which may significantly impact both work attendance and performance. School teachers represent an occupational group among which there appears to be a high prevalence of neck and/or shoulder pain (NSP) and low back pain (LBP). Epidemiological data on NSP and LBP in South African teachers are limited.Objectives: To determine the prevalence of NSP and LBP among primary school teachers in the Central Durban area of KwaZulu-Natal, South Africa; to identify predominant occupational factors associated with NSP and LBP pain; and to highlight key actions associated with such factors so as to direct future preventive measures/interventions.Methods: A cross-sectional, questionnaire-based study was conducted on teachers from 12 randomly selected primary schools.Results: Among the 97 completed questionnaires, the prevalence of NSP and LBP was 80.4% and 68.0%, respectively. There was no association between age and NSP (p < 0.250) or LBP (p < 0.595). However, there were higher prevalence rates of NSP and LBP among the 45-54 years age group (39.2% and 33.0%, respectively). Factors associated with NSP included marking of assessments (56.7%; n = 55), and writing on a blackboard (39.2%; n = 38); prolonged standing was associated with LBP (83.5%; n = 81). These findings highlighted specific actions, such as forward-bending of the head for prolonged periods (61.9%; n = 60), backward-bending of the head for prolonged periods (20.6%; n = 20), and reaching/stretching with arms above chest height (41.2%; n = 40). Conclusion: Key occupational factors associated with MSP, and associated actions identified in this study can be used as a basis to direct strategies that can be applied to reduce the prevalence of MSP and the onset of MSD in teachers

Artisanal fisherwomen/shellfish gatherers: analyzing the impact of upper limb functioning and disability on health-related quality of life / Pescadoras artesanais/marisqueiras: análise do impacto da funcionalidade e incapacidade de membros superiores sobre a qualidade de vida relacionada com a saúde

Abstract The aim is to analyze upper limb functioning and disability, and its association with health-related quality of life among artisanal fisherwomen from Bahia, Brazil. Cross-sectional epidemiological study was conducted with a sample of 209 fisherwomen. Structured questionnaires were used for socio-demographic and comorbidity information, as well as the instruments Disabilities of the Arm, Shoulder and Hand (DASH) and Short-Form Healthy Survey (SF-36) respectively, to evaluate the upper limbs and health-related quality of life. The results demonstrated that the presence of musculoskeletal disorders in the upper limbs directly affects the values of the DASH instrument and the SF-36v01 questionnaire scores, while also generating a negative correlation between the DASH and SF-36v01. The varying functioning abilities, pain and social aspects negatively affect upper limb function, and the daily activities and work of fisherwomen. The presence of chronic disease and the absence of intervention and rehabilitation for these professionals, that could produces, in a long-term, cases of disability.

Resumo O objetivo foi analisar a incapacidade e a funcionalidade de membros superiores e verificar sua associação com a qualidade de vida relacionada com a saúde de pescadoras artesanais da Bahia, Brasil. Estudo epidemiológico, de corte transversal, envolvendo uma amostra de 209 pescadoras artesanais. Foram utilizados questionários estruturados para informações sociodemográficas e comorbidades e os instrumentos Disabilities of the Arm, Shoulder and Hand (DASH) e Medical Outcomes Study 36-Item Short-Form Healthy Survey (SF-36), para, respectivamente, avaliação dos membros superiores e qualidade de vida relacionada com a saúde. Os resultados encontrados demonstram que a presença de distúrbios musculoesqueléticos (DME) em membros superiores afeta diretamente os valores do instrumento DASH e os escores do SF-36v01, bem como a correlação negativa encontrada entre o DASH e os domínios do SF-36v01. As variáveis capacidade funcional, dor e aspectos sociais afetam negativamente a funcionalidade de membros superiores e as atividades do cotidiano e do trabalho de pescadoras artesanais. A presença de doença crônica e a ausência de intervenção e reabilitação desses profissionais geram, a longo prazo, casos de incapacidade.
