Effects of functional training on pain and functional capacity in elderly women / Efeito do treinamento funcional na dor e capacidade funcional de mulheres idosas

Abstract Introduction: The growing rate of elderly people in the world can became a public health problem when they exhibit insufficient levels of physical activity, which can increase chronic pain and lead to functional disability. Objective: To analyze the effects of functional training on pain and functional capacity in elderly women. Methods: A non-randomized controlled clinical trial was conducted with 32 elderly women, divided into two groups: functional training (FT: n = 17) and control group (CG: n = 15). Functional capacity was analyzed using the Physical Fitness Test for the Elderly. Pain was assessed by reports of musculoskeletal discomfort symptoms and their characteristics using the Nordic Musculoskeletal Pain Questionnaire and pain visual analog scale (VAS). The functional training program was applied for 12 weeks at a frequency of three times a week. Results: Significant effects after the intervention in the FT group were observed, with pain reduction, increased flexibility and resistance for lower limbs, and cardiorespiratory capacity (p < 0.05). Conclusion: The functional training program in elderly women was effective in improving the variables of lower limb flexibility, pain perception, lower limb strength resistance and cardiorespiratory capacity.

Incidence and factors associated with low back pain in adolescents: A prospective study.

BACKGROUND: Low back pain (LBP) is a common complaint among children and adolescents and can negatively impact their physical and mental health. Although previous studies investigating the incidence of low back pain (LBP) in children and adolescents have been performed in high income countries, it is unclear whether countries such as Brazil would show similar incidence rates. OBJECTIVE: To determine the incidence and to identify predictors of new episodes of LBP in high school students. METHODS: This is a 1-year longitudinal study of high school students from public schools in the city of Bauru, Sao Paulo. Collected clinical data were: demographic and socioeconomic factors, information on the use of electronic devices, mental health status (the Strengths and Difficulties Questionnaires), level of habitual physical activity (Baecke Physical Activity Questionnaire), and incidence of LBP (measured with question about LBP in the past 12 months and the Nordic Musculoskeletal Questionnaire). Descriptive analysis and bivariate and multivariate logistic regressions were performed. RESULTS: The cumulative incidence of new LBP episodes for the total cohort of 757 high school students was 18.9% (95% CI: 16.2, 21.8). The cumulative incidence was 14.8% (95% CI: 11.7, 18.5) for male students and 24.1% (95% CI: 19.8, 29.9) for female students. Being a female student (OR = 1.78; 95% CI: 1.23, 2.59), sitting posture while using tablet (OR = 4.34; 95% CI: 1.19, 16.60), daily time spent on tablet (OR = 3.21; 95% CI: 1.41, 7.30), daily time spent on mobile phone (OR =1.49; 95% CI: 1.11, 2.00), lying posture while using mobile phone (OR = 1.49; 95% CI: 1.05, 2.12), and mental health status (OR = 2.81; 95% CI: 1.76, 4.48) were identified as predictor variables. CONCLUSION: Our findings showed that one in five high school students reported having a LBP episode over the last year. The predictors found to be associated with low back pain include those related to sex, time and posture while using electronic devices, and mental health status.

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.

Low back pain and some associated factors: is there any difference between genders?

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=3.00 [1.31-6.88]) and over 60 (PR=4.52 [2.02-10.12]), smoking (PR=2.47 [1.20-5.11]), fewer years of formal education (0-4 years) (PR=6.37 [2.15-18.62]), and hypertension (PR=2.27 [1.15-4.50]). For women, the associated factors were occupational activities that involved heavy lifting (PR=1.80 [1.03-3.16]), standing posture leaning forward (PR=2.04 [1.20-3.44]), sitting posture leaning forward (PR=2.17 [1.24-3.82]), and sitting at the computer three or more days per week (PR=4.00 [1.44-11.11]). Widowed or divorced participants were more likely to report LBP, in both men (PR=3.06 [1.40-6.66]) and women (PR=2.11 [1.15-3.88]). CONCLUSION: This study reveals high prevalence of low back pain in a seven day period. Older age, low education, hypertension, and smoking were associated with LBP in men. Occupational and ergonomic factors were associated with LBP in women. Marital status was associated with LBP in both genders.

Results Prevalence of insufficient physical activity was 35.0% (95% CI: 31.2-38.9). Zero to four years of schooling [PR=2.35; 95% CI: 1.07-5.15], working in sitting position [PR=1.52; 95% CI: 1.02-2.48], and number of days at the computer [PR=4.60; 95% CI: 2.38-14.28] remained in the final model for females, whereas 0-4 years [PR=2.30; 95% CI: 1.21-4.06] or 5-8 years [PR=3.70; 95% CI: 0.79-4.00] of schooling, working in sitting position [PR=2.22 95% CI: 1.36-3.62], number of days at the computer [PR=2.04; 95% CI: 1.26-3.32], and number of days of TV viewing [PR=2.12; 95% CI: 1.03-4.36] remained in the final model for males. Conclusion High prevalence of insufficient practice of physical activity is associated with schooling, working in sitting position, and number of days at the computer and TV viewing.

Resumo Introdução A prática insuficiente de atividade física associada a alguns fatores relacionados aos hábitos de vida aumenta o risco de doenças crônicas não transmissíveis e reduz a qualidade de vida da população. Objetivo Identificar o padrão de atividade física e os fatores associados em adultos de 20 anos ou mais. Método Inquérito populacional, transversal, com 600 indivíduos entrevistados em seus domicílios. Foram coletados os seguintes dados: aspectos demográficos, socioeconômicos, comportamentais, do trabalho e nível de atividade física. Realizaram-se as análises descritiva e bivariada e a regressão de Poisson. Resultados A prevalência de prática insuficiente de atividade física foi de 35% (IC 95%: 31,2-38,9). O nível educacional de 0 a 4 anos [RP = 2,35; IC95%: 1,07-5,15], o trabalho sentado [RP = 1,52; IC95%: 1,02-2,48] e o número de dias no computador [RP = 4,60; IC95%: 2,38-14,28] permaneceram no modelo final para o sexo feminino. Para o sexo masculino, permaneceram: o nível educacional de 0 a 4 anos [RP = 2,30; IC95%: 1,21-4,06] ou o de 5 a 8 anos [RP = 3,70; IC95%: 0,79-4,00], o trabalho sentado [RP = 2,22; IC95%: 1,36-3,62], o número de dias no computador [RP = 2,04; IC95%: 1,26-3,32] e o número de dias na TV [RP = 2,12; IC95%: 1,03-4,36]. Conclusão Houve elevada prevalência de prática insuficiente de atividade física e associação com nível de escolaridade, trabalho sentado e número de dias no computador e na TV.

Prevalence and factors associated with neck pain: a population-based study.

BACKGROUND: Neck pain is a musculoskeletal condition with high prevalence that may affect the physical, social, and psychological aspects of the individual, contributing to the increase in costs in society and business. OBJECTIVE: To determine the prevalence of neck pain and associated factors in a population-based sample of adults aged 20 and more. METHODS: Cross-sectional study based on a population survey. A total number of 600 individuals were interviewed in their homes, and the following data were collected: (1) participant characteristics (demographic, socioeconomic, and work-related aspects) using a pre-coded questionnaire; (2) physical activity level using the IPAQ; and (3) musculoskeletal symptoms using the Nordic questionnaire. Descriptive, bivariate, and Poisson regression analyses were performed. RESULTS: The prevalence of neck pain was 20.3% (95% CI 17.3-23.7). The adjusted analyses showed that individuals who were widowers or separated (PR=2.26; 1.42-5.88), had a low income (PR=1.32; 1.22-6.27) or low educational level (PR=1.83; 1.02-5.26), worked while sitting and leaning (PR=1.55; 1.08-2.40), and who reported having two or more diseases (PR=1.71; 1.55-6.31) remained associated with neck pain. CONCLUSION: This study reveals the high prevalence of neck pain and remarkable association with widowed/separated people who have low income and low educational level, who perform their occupational activities in sitting and leaning positions, and who reported having two or more diseases. Knowledge of these risk factors will contribute to the development of forms of assistance in which neck pain can be prevented and better managed.
