Is the prevalence of asthma and related symptoms among Brazilian children related to socioeconomic status?

Objective. To evaluate the relationship between socioeconomic status (SES) and the prevalence of asthma and related symptoms among Brazilian children. Methods. The International Study of Asthma and Allergies in Childhood (ISAAC) written questionnaire was applied to 23,457 six- to seven- year-old schoolchildren (SC) and 58,144 thirteen- to fourteen-year-old adolescents (AD) from 20 Brazilian cities. SES was evaluated by infant mortality index, poverty index, and average nominal income for people older than 10 years of age. Results. Current asthma ranged from 16.5% to 31.2% among SC and from 11.8% to 30.5% among AD and severe asthma from 2.9% to 8.5% (SC) and 2.6% to 9.1% (AD). Higher values were observed in Brazilian-Northern, -Northeastern and -Southeastern centers. No significant association between SES and prevalence of asthma and related symptoms was observed. Conclusions. In Brazil, the prevalence of asthma and related symptoms is quite variable and independent of SES. Copyright © 2008 Informa Healthcare USA, Inc.

Reality and language in The Voyage Out, by Virginia Woolf

This article discusses one of Virginia Woolf's greatest literary concerns: the difficulty of expressing human experience through language. The focus is on The Voyage Out, her first novel, published in 1915, particularly the conflicts and contrasts present not only in the trajectory of Rachel Vinrace, the main character, but also in the structure of the novel itself, which establish a constant tension between reality and language.

Fractional order and dynamic simulation of a system involving an elastic wide plate

Numerous researchers have studied about nonlinear dynamics in several areas of science and engineering. However, in most cases, these concepts have been explored mainly from the standpoint of analytical and computational methods involving integer order calculus (IOC). In this paper we have examined the dynamic behavior of an elastic wide plate induced by two electromagnets of a point of view of the fractional order calculus (FOC). The primary focus of this study is on to help gain a better understanding of nonlinear dynamic in fractional order systems. © 2011 American Institute of Physics.

Physical inactivity and related barriers: A study in a community dwelling of older brazilians

This study sought to investigate the prevalence of physical inactivity and related barriers in older Brazilian adults. A cross-sectional, population-based study was conducted, and a stratified random sampling procedure was used. A total of 359 older adults were interviewed. The long version of the International Physical Activity Questionnaire (IPAQ) and the Questionnaire of Barriers to Physical Activity Practice were used to assess physical activity level and barriers, respectively. No statistically significant difference was observed on the prevalence of physical inactivity in either gender or age groups. Regarding barriers, the proportion of 9 out of 22 barriers was statistically significant between men and women. Self-reported physical inactivity/activity in older Brazilian adults continues to be a concern. Uncommonly, older males reported a higher prevalence of physical inactivity compared to their counterparts. Additionally, physical inactivity prevalence continued to increase with the aging process. Yet, personal barriers such as lack of time and poor health were strongly associated with physical inactivity. The results of this study may help health professionals and public policy makers to better address the issues related to a healthy lifestyle among older adults and promote physical activity among Brazilian older adults and in other countries with similar characteristics. © 2012 Sebastião Gobbi et al.

Effects of strength and balance training on the mobility, fear of falling and grip strength of elderly female fallers

The aim of this study was to evaluate the effects of virtual reality and strength training on the balance, fear of falling and handgrip strength of older women with a history of falls. The fear of falling, mobility and grip strength were evaluated in 11 elderly fallers (72.4 ± 5.2 years). The faller group was submitted to 12 weeks of virtual reality and muscle strength training. The results showed improvement in mobility (p = 0.0004) and in the fear of falling (p = 0.002). No significant difference was observed for hand grip strength. It can be concluded that virtual reality and muscle strength interventions are beneficial for mobility and fear of falling in older women with a history of falls.
