HighlightsThe study population shows high prevalence of neck pain.The factors were widowed, income, educational level, sitting posture and diseases.Prevention should emphasize sociodemographic, behavioral, and ergonomic factors.

Objective: To compare men and women with low back pain and identify the prevalence and some of its associated factors in a population-based sample of adults aged 20 and over a seven day period. Methods: Cross-sectional study based on a population survey. 600 individuals were interviewed on the following: (1) characteristics of the participants (i.e. demographic, socioeconomic, and labor aspects); (2) physical activity level (IPAQ); (3) musculoskeletal symptoms (Nordic Questionnaire). Descriptive, bivariate, and Poisson regression analyses were performed. Results: Overall prevalence of LBP was 28.8%, being 39.0% in men and 60.9% in women. The measured associated factors in men were age between 36 and 59 years (PR = 3.

Musculoskeletal pain in the shoulder is considered one of the most prevalent causes of pain and disability in adults. To verify the prevalence of shoulder pain and correlated factors in adults aged 20 years or older in cross-sectional study with 600 individuals interviewed through questionnaires: (1) participants characterization; (2) level of physical activity; (3) reported morbidities; and (4) musculoskeletal symptoms. Descriptive, bivariate, and Poisson regression analyses were performed. The prevalence of pain in the shoulder was 24% (CI 20.3%-27.5%). Being 60 years or older (PR=2.14; 1.33-2.45), female (PR=1.92; 1.29-285), using the computer more than three times a week (PR=1.55; 1.01-2.32), working in a sitting position (PR=1.64; 1.03-2.59), standing up leaning the body forward (PR=1.54; 1.00-2.37), and reporting two or more morbidities (PR=3.31; 1.97-5.57) were all indicators of shoulder pain. This study discloses a high prevalence of shoulder pain and a strong relation with women, age, those who use the computer more than three times a week, those who execute occupational activities sitting and standing up leaning the body forward, and those who report two or more diseases.

INTRODUÇÃO: A dor cervical é uma condição musculoesquelética com alta prevalência que pode afetar os aspectos físicos, sociais e psicológicos dos indivíduos, contribuindo para o aumento de custos na sociedade e nos negócios. OBJETIVOS: Determinar a prevalência de dor cervical e analisar a associação com variáveis sociodemográficas e dispositivos eletrônicos. MÉTODOS: Foi realizado um estudo observacional transversal com uma amostra de 1143 universitários, que responderam ao questionário sobre aspectos sociodemográficos, uso de dispositivos eletrônicos e o questionário nórdico. Foram realizadas análises descritivas, bivariadas e de regressão de Poisson. RESULTADOS: A prevalência de dor cervical foi de 66,7% (IC 63,8 a 69,3), sendo que, 57,6% (IC 52,9 a 62,1) em homens e 72,3% (IC 68,8 a 79,4) em mulheres. Na análise ajustada, o sexo feminino (RP = 1,92, 1,49-2,47), tempo de uso da TV acima de 3 horas por dia (RP = 1,35; 1,05 - 1,79), tempo de uso do computador acima de 3 horas por dia (RP = 1,41; 1,08 - 1,85), tempo de uso de videogame acima de 3 horas por dia (RP = 1,42; 1,02 - 1,97), uso do tablet à distância do olho na tela acima de 20 cm (RP = 1,08, 1,01 - 1,17), postura deitada no uso do celular (RP = 1,67, 1,04 - 1,72), postura semi-deitada no uso do celular (RP = 1,28; 1,02 - 1,65), postura sentada no uso do tablet (RP = 1,54; 1,03 - 2,38), postura deitada no uso do tablet (RP = 1,83; 05 - 3,18) e usar o tablet por duas ou mais horas por dia (RP = 2,28, 1,15 - 4,49) permaneceu associado à dor cervical. CONCLUSÃO: Existe alta prevalência de dor cervical em estudantes universitários e associação marcante com o sexo feminino e com o uso de dispositivos eletrônicos.

Introduction: Primary headaches, defined as disorders in themselves caused by independent pathomechanisms and not by other disorders, are prevalent in university students and considered one important health problems in the world. Objective: To investigate the prevalence of primary headaches and analyze associations with sociodemographic characteristics and the use of electronic devices by university students. Methods: A cross-sectional observational study analysis was carried out with a sample of 1,143 students of both genders who responded to the questionnaire on demographic, socioeconomic aspects, use of electronic devices, and on the primary headaches. Descriptive analysis, bivariate analysis, and Poisson regression were performed. Results: The overall prevalence of primary headache of 60.7%, being that, in relation to the type, 33.2% presented tension-type headache, 54.3% migraine, and 12.3% other types of headache. Regression analysis showed that female gender and income of up to two minimum wages were associated with primary headache and migraine type. The primary headache was associated with subjects of the white race; watching television and playing video games for more than 3 hours per day, for example. The sitting posture, semi-lying down, and distance from the eyes to the mobile phone and tablet longer than 20 cm were associated with primary headache and the three types of headaches. Conclusion: The results allow us to conclude that there is a high prevalence of primary headaches in college students and that socioeconomic factors related to the use of electronic devices are associated with the presence of primary headaches.
