Dor crônica em idosos residentes em São Paulo, Brasil: prevalência, características e associação com capacidade funcional e mobilidade (Estudo SABE)

Abstract: O objetivo foi identificar a prevalencia, as caracteristicas e a associacao da dor cronica com capacidade funcional. Estudo transversal com amostra populacional feito por entrevista domiciliar com idosos residentes na cidade de Sao Paulo, Brasil. Dor cronica foi aquela com duracao minima de seis meses. Nas analises estatisticas utilizou-se teste de associacao de RaoScott com significância de p < 0,05. Dor cronica ocorreu em 29,7% dos idosos (IC95%: 25,4-33,9); os locais mais frequentes foram a regiao lombar (25,4%) e os membros inferiores (21,9%) e foi moderada em 45,8% das vezes e intensa em 46% dos idosos. Dor cronica esteve associada a maior dependencia e pior mobilidade (p < 0,001).

The new Brazilian traffic code and some characteristics of victims in southern Brazil

Abstract: Objective—The aim was to study characteristics of traffic accident victims before and after the implementation of the new Brazilian traffic code, in January 1998. Subjects and methods—The study population was car and motorcycle occupants seen in a pre-hospital care service in Londrina, Parana State (Brazil) before the introduction of the new Brazilian traffic code, from 22 January to 21 July 1997, and after its implementation during the same period in 1998. Victims were analyzed over the time periods according to helmet and seat belt use, gender, underage driving, and alcohol on the breath. Results—Use of seat belts increased from 45% to 62.6% and of helmets from 31.2% to 66.2% after the introduction of the new Brazilian code. The proportion driving under age 18 and with perceptible alcoholic breath declined significantly only among motorcycle riders. There was a 20% decline in car occupant injuries along with a 9% reduction in motorcycle related injuries after the change of the law. Conclusion—Results favor the hypothesis that rigorous legislation increases safer practices in traffic, at least during the first months of its implementation.

Effect of resistance training on phase angle in older women: A randomized controlled trial

Abstract: Phase angle (PhA) is an angular-derived bioelectrical impedance parameter based on resistance and reactance that has been widely used in different populations as an objective indicator of cellular health. The purpose of this study was to analyze the effect of resistance training (RT) on PhA in older women. Forty-one older women (67.2 ± 4.5 years, 64.0 ± 12.3 kg, 154.7 ± 5.2 cm, and 26.6 ± 4.8 kg/m2) were randomly assigned to one of two groups: a training group (TG, n = 19) that underwent progressive RT for 12 weeks (eight exercises, three sets of 10–15 repetitions maximum, three times per week) or a control group (CG, n = 22) that did not perform any type of exercise during the intervention period. Resistance, reactance, PhA, total body water (TBW), intracellular (ICW) and extracellular (ECW) water were assessed by spectral bioelectrical impedance. There was a significant group by time interaction (P < 0.05) for PhA, TBW, and ICW in which only the TG increased their scores after the intervention period (PhA = +6.5%, TBW = +2.8%, and ICW = +5.1%). The results suggest that progressive RT promotes an increase in PhA in older women. Therefore, the PhA seems to be a good parameter to assess changes in cellular health during RT intervention.
