ABSTRACT BACKGROUND: Neck pain is a major public health problem. OBJECTIVE: The aim of the present study was to determine the prevalence of neck pain among high school students and to analyze associations with sociodemographic variables, use of electronic devices, habitual physical activity practices and mental health problems. DESIGN AND SETTING: Cross-sectional epidemiological study on a sample of high school students in the city of Bauru, São Paulo, Brazil. METHOD: Participants were selected through cluster sampling in two stages and data were collected via face-to-face interviews. Data collection comprised the following steps: 1. sociodemographic characteristics; 2. use of electronic devices; 3. habitual physical activity levels; 3. mental health; and 4. neck pain. RESULTS: A total of 1,628 participants were interviewed. The prevalence of neck pain was 49.1% (95% confidence interval, CI 46.7 to 51.5), with 40.4% (95% CI 37.0 to 43.7) in men and 57.5% (95% CI 54.2 to 60.9) in women. The variables associated with in neck pain were: female (prevalence ratio, PR = 2.04), use of cell phone in standing posture (PR = 1.47), use of tablet in sitting posture (PR = 1.72), length of computer use greater than 3 hours/day (PR = 1.54), length of cell phone use greater than 3 hours/day (PR = 1.54), length of tablet use greater than 3 hours/ day (PR = 1.34) and mental health problems (PR = 1.56). CONCLUSION: There is high prevalence of neck pain among students and striking associations with female sex, use of electronic devices and mental health problems.

Factors associated with intensity and frequency of low back pain in high school students / Fatores associados à intensidade e a frequência de dor lombar em estudantes do ensino médio

INTRODUCTION: Low back pain is frequent among schoolchildren and the variables related to high intensity and high back frequency are important predictors for the increase of such complaints in adulthood. OBJECTIVE: To determine the high intensity and high frequency of low back pain and its associated factors in high school students. METHODS: This cross-sectional study included 760 students (319 boys and 441 girls) who reported low back pain. Demographic, socioeconomic, electronic devices, habitual physical activity practice, mental health, and high frequency and high intensity low back pain data were collected. Descriptive analyzes and bivariate and multivariate logistic regressions were used. RESULTS: Of the total number of subjects with low back pain, 14.6% reported high frequency of pain, being 36.9% boys and 63.1% girls, while 42.6% reported high intensity, being 35.8% boys and 47.2% girls. The variables associated with the high frequency of low back pain were altered mental health, posture lying on the use of tablet, time of daily use of the cell phone and distance of the screen to the eyes of the computer user, while the female sex, mental health problem, posture lying on the use of cell phone and the distance of the screen to the eyes of the computer user with severe intensity of low back pain. CONCLUSION: The demographic factors and related to the use of electronic devices were associated with high intensity and high frequency of low back pain.

Primary headache and factors associated in university students: a cross sectional study / Cefaleia primária e fatores associados em estudantes universitários: um estudo transversal

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.

INTRODUÇÃO: As dores de cabeça primárias, definidas como perturbações em si mesmas, causadas por patomecanismos independentes e não por outras perturbações, são prevalentes em universitários e considerada um importante problema de saúde mundial. OBJETIVO: Investigar a prevalência de cefaleia primária e analisar associações com características sociodemográficas e uso de dispositivos eletrônicos em estudantes universitários. MÉTODOS: Foi realizado um estudo observacional transversal com uma amostra de 1143 estudantes de ambos os sexos, que responderam ao questionário sobre aspectos demográficos, socioeconômicos, uso de dispositivos eletrônicos e cefaleia primária. Foram realizadas análises descritivas, análises bivariadas e regressão de Poisson. RESULTADOS: A prevalência geral de cefaleia primária de 60,7%, sendo que, em relação ao tipo, 33,2% apresentavam cefaleia tensional, 54,3% enxaqueca e 12,3% outros tipos de cefaleia. A análise de regressão mostrou que o sexo feminino e a renda de até dois salários-mínimos estavam associados à cefaleia primária e a enxaqueca; a cefaleia primária está associada a indivíduos da raça branca; assistir televisão e jogar videogame por mais de 3 horas por dia foi associado ao tipo tensional, a enxaqueca e cefaleia primária; a postura sentada, semideitada e distância dos olhos ao telefone celular e tablet com mais de 20 cm com a cefaleia primária e aos três tipos específicos. CONCLUSÃO: Os resultados permitem concluir que existe alta prevalência de cefaleia primária em estudantes universitários e que fatores socioeconômicos e relacionados ao uso de dispositivos eletrônicos estão associados à presença de cefaleia primária.
