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.

Objective: To determine the prevalence of low back pain in children and its relationship with gender, age, exercise practice and sedentary activities (time on TV and on computer and/or video game). Methods: We conducted a cross-sectional study with a sample of 1,461 students, being 754 males and 707 females enrolled in the 5th to 8th grades of all five local elementary schools of urban Ourinhos, SP, Brasil, aged 10-14 years old, from whom sociodemographic data, time spent on sedentary activities such as TV and computer and/or video game were collected. We conducted a descriptive, bivariate and multivariate binary logistic regression. Results: The results showed that the prevalence of low back pain in the sample was 18.5%, being 15.5% in boys and 21.6% in girls. Low back pain was associated to the female gender, age range between 12-14 years and the habit of watching TV more than three times a week and over 3 hours per day. Conclusion: The students analyzed showed high prevalence of low back pain related to gender, age and habit of watching TV. Appropriate interventions should be implemented to reduce the occurrences of back pain in schoolchildren. Level of Evidence III, Cross Sectioning.

92 más, residentes de la ciudad de Bauru, São Paulo, y su asociación con la cantidad de morbilidades referidas. Se realizó una encuesta poblacional mediante una muestra compleja en dos estadios, con un total de 600 participantes de la zona urbana de Bauru. Para la recolección de datos se utilizó los siguientes instrumentos: 1. caracterización de los participantes (aspectos demográficos, socioeconómicos, nivel de actividad física y hábito de fumar); 2. morbilidades (referida mediante la pregunta: "En el último año, usted ha recibido el diagnóstico médico de alguna enfermedad?"); 3. calidad de vida (utilizando el cuestionario Medical Outcomes Study 36 -Item Short-Form Health Survey -SF-36). Se realizó análisis descriptivos y bivariados, mediante la prueba T de Student y Anova. Se observó que 70,5% presentaron por lo menos una enfermedad, y las principales referidas fueron la hipertensión, la artrosis, la depresión y la diabetes. En relación a la asociación entre los números de enfermedades, las personas mayores y las que refirieron tres o más enfermedades presentaron peores scores de QVRS en todos los dominios físicos y en las limitaciones por aspectos sociales y emocionales.El mayor número de morbilidades se asoció a los menores scores de calidad de vida relacionada a la salud.Palabras clave | Morbilidad; Calidad de Vida; Cuestionarios.

ObjectiveTo verify the association among sociodemographic variables, physical activity level and health-related quality of life in adults aged 20 years and over.MethodsPopulation-based study, with household sample by clusters. The dependent variables were the PCS and MCS scores of the instrument 36-Item Short-Form Health Survey (SF-36), the independent variables were gathered in sociodemographic characteristics and the level of physical activity. Absolute and relative frequency distributions were used for categorical variables and bivariate analysis, using Student’s t-test and ANOVA and multivariate using non-conditional logistic regression.ResultsOf the 600 interviewees, the mean PCS score for men was 80.2 and for women 74.6, while for MCS, 83.8 (±16.9) and 76.5 (±23.3), for men and women, respectively. Women tend to report lower scores than men in all domains: men (OR=4.83) and women (OR=4.80) were older (OR=4.34) (OR=3.57) and sedentary women (OR=1.90) were associated with lower PCS scores, while older men (OR=3.96) and widowed and separated’ (OR=3.03) had lower MSC scores.ConclusionHRQoL was associated with advancing age and schooling, in both sexes, sedentary women and widowed and separated men.

Introduction: The aging process causes losses that lead to decreased balance, gait speed and functional capacity and, therefore, there is a need of specific protocols to work preventively these variables, which will contribute to the decrease in the frequency of falls in this population. Objective: Verify the effect of a program of multisensory and closed kinetic chain exercises on the functional capacity and balance in elderly women. Methods: Randomized clinical trial masked (blind). Subjects were 32 elderly women from the Centro de Convivência of the Bauru Department of Social Welfare (Secretaria de Bem-Estar Social de Bauru) distributed in two groups: control (CG = 15) and experimental (EG = 17). Interventions: The program of multisensory and closed kinetic chain exercises was applied during an hour, once a week, for 12 weeks. Main measures: Functional capacity was measured by Timed Up and Go (TUG) and the 10-meter walking test (TC10) and their balance by the Berg Balance Scale (BBS). Results: Regarding the comparison between the moments M1 and M2 of the EG after the intervention, there was a statistically significant increase in the functional capability (p = 0.00006), walking speed (p = 0.0008) and balance (p = 0.0006). Conclusion: The multisensory and closed kinetic chain-training program indicated a beneficial effect in the improvement of the elderly women balance and functional performance.

Introduction: Back pain has become a serious public health problem. Objective: To determine the prevalence of back pain in a population-based sample of subjects over 20 years old living in the city of Bauru (São Paulo, Brazil) and to analyze the associations to variables-sociodemographic, ergonomic and lifestylerelated -and to morbidity. Methods: a cross-sectional study which evaluated 600 adults over 20 years old, both gender and living in the city. We used a structured protocol and the Nordic questionnaire. Also, we developed a descriptive analysis, bivariate and multivariate by binary logistic regression. Results: The prevalence of back pain was of 50.3% (CI 46.3 to 54.3), since 42.3% (CI 36.9 to 48.0) in men and 57.6% (CI 51.9 to 63.0) in women, with statistical significant difference (p = 0.001). Different variables remained in final models when assessed by gender. For male to be widowed and divorced and smoking habits and, for women to be widowed and divorced, to work in seated position and to perform occupational activities that demand carrying and lifting weight. Conclusion: We verified high prevalence in back pain in the population

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.
