RESUMO

UNLABELLED: The objective of this study is to evaluate the effectiveness of laser and LED therapies, associated with lateral decubitus position and flexion exercises of the lower limbs in patients with lumbar disk herniation (LDH). It is a randomized blinded clinical trial. Fifty-four subjects with LDH L4-L5 and L5-S1 were selected and randomly allocated into groups: laser 904 nm, placebo, and LED 945 nm. The numbers of subjects for each group that completed the treatment were 18, 13, and 18, respectively. Twelve points over the lumbar spine region (L2 to S1) and eight points on the injured thigh in the path of the lumbar roots L5 and S1 were irradiated. Irradiation parameters for each point were as follows: laser wavelength 904 ± 10 nm, average power 0.038 ± 20 % W, irradiated area 0.16 cm(2), energy per point 4 J, and treatment time per point 104 s; LED wavelength 945 ± 15 nm, power 0.1 W, irradiated area 1.0cm(2), energy per point 4 J, and treatment time per point 40 s. Lateral decubitus opposite to the side of the radicular was the standard position for all patients. After phototherapy and laser placebo sessions, the subjects performed sequences of flexion exercises of the lower limbs (ten per session) for 15 daily sessions. VARIABLES STUDIED: pain intensity assessed by visual analog scale (VAS), degree of flexion of the affected hip measured by the universal goniometer and functional capacity assessed by the Oswestry Disability Index. The three groups had statistically significant improvement in lumbar and radicular pain, in hip mobility, and in the functional disability index (p ≤ 0.001). There was a statistically significant difference (p = 0.024) in radicular pain between the groups, gait claudication and Oswestry Disability Index. We can conclude that in the treatment of L4-L5 and L5-S1 LDH with radiculopathy, LED, associated with lateral decubitus position and flexion exercises of the lower limbs, showed better therapeutic performance for radicular pain, gait claudication, and functional disability.

RESUMO

PURPOSE: Criterion-referenced cut-points for health-related fitness measures are lacking. This study aimed to determine the associations between aerobic fitness and high blood pressure levels (HBP) to determine the cut-points that best predict HBP among adolescents. METHOD: This cross-sectional school-based study with sample of 875 adolescents aged 14-19 years was conducted in southern Brazil. Aerobic fitness was assessed using the modified Canadian Aerobic Fitness Test (mCAFT). Systolic and diastolic blood pressure were measured by the oscillometric method with a digital sphygmomanometer. Analyses controlled for sociodemographic variables, physical activity, body mass and biological maturation. RESULTS: Receiver Operating Characteristic (ROC) curves demonstrated that mCAFT measures could discriminate HBP in both sexes (female: AUC = 0.70; male: AUC = 0.63). The cut-points with the best discriminatory power for HBP were 32 mL·kg-1·min-1 for females and 40 mL·kg-1·min-1 for males. Females (OR = 8.4; 95% CI: 2.1, 33.7) and males (OR: 2.5; CI 95%: 1.2, 5.2) with low aerobic fitness levels were more likely to have HBP. CONCLUSION: mCAFT measures are inversely associated with BP and cut-points from ROC analyses have good discriminatory power for HBP.

RESUMO

The aim of this study was to identify prevalence and factors associated with violent behavior among adolescents in Aracaju and Metropolitan region. The study included 2207 adolescents (16.03±1.08 years old) enrolled in high schools of the State Public Network. Violent behavior was identified from question 14 of the YRBS-2007 questionnaire with responses categorized as "never" and "one or more times." Higher prevalence in males in relation to risk factors for adoption of violent behavior was found: cigarette consumption (7.3%), alcohol consumption (39.1%), and marijuana use (3.4%). Data analysis used descriptive statistics and logistic regression with hierarchical model at two levels: (a) sociodemographic variables and (b) behavioral variables. For both sexes, association between violent behavior and cigarette smoking (OR=3.77, CI 95%=2.06-6.92 and OR=1.99, CI 95%=1.04 to 3.81, male and female, resp.) and alcohol consumption (OR=3.38, CI 95%=2.22 to 5.16 and OR=1.83, CI 95%=1.28 to 2.63, male and female, resp.) was verified. It was concluded that violent behavior is associated with the consumption of alcoholic beverages and cigarettes among adolescents.

RESUMO

INTRODUCTION: The Telephone Survey has several attractions, such as low operational costs and speed the process, when compared to the Household Survey. However, the exclusion of house holds without a landline phone canpose a serious question of the valid it yof the estimates. OBJECTIVE: Evaluating the use of post stratification adjustments to correct the potential biasdue to low coverage of landline phonein the results published in the Vigitel system. METHODS: We compared the prevalence obtained by the Household Survey and the Vigitel, in Aracaju, Sergipe, where 49% of households had a telephone, calculating the differences measured between the surveys thatused the square root mean square error as a measure of accuracy of the estimate. RESULTS: The Household Survey showed ten variables associated with landline phone. From this set of variables, post stratification weights corrected the potential bias of the consumption of beans in five or more days per week, vegetables intake regularly and recommended self-assessment of health as bad and morbidity of diabetes,while the weights partially eliminated the bias of the prevalence of asthma, possession of health insurance coverage and prevention of breast cancer in women aged 50 to 59 years. CONCLUSIONS: In order to reduce the potential bias in the results published by Vigitel system, in areas with low telephone coverage, it becomes necessary to use alternative weighting procedures and selection strategy of external variables for construction of post-stratification weights.

RESUMO

FUNDAMENTO: Uma das dificuldades para a manutenção da aderência de longo prazo a exercícios é a distância entre domicílio e local de exercício. OBJETIVO: Determinar, para um programa de exercício físico supervisionado (PES) privado, a influência da distância domicílio-PES sobre a aderência. MÉTODOS: Foram identificados 976 sujeitos e selecionados 796 que atendiam aos critérios de inclusão. A distância domicílio-PES foi obtida pelo Google Maps. A aderência foi determinada em quartis (meses): de 1 a 4, 5 a 12, 13 a 36 e mais de 36. As condições clínicas foram estratificadas como: saudáveis; obesos e/ou hipertensos e/ou dislipidêmicos e/ou diabéticos sem doença coronariana; coronariopatas e outros agravos como câncer, pânico e doenças respiratórias. A distância domicílio-PES foi dividida em (km): até 1, entre 1 e 3, entre 3 e 10, e mais de 10. Para a análise estatística, utilizaram-se a ANOVA Kruskal-Wallis e o quiquadrado. RESULTADOS: Dos participantes, 46% residiam até 3 km, 39% entre 3 e 10 km e cerca de 15% moravam a mais de 10 km do local de realização do PES. Não foram encontradas diferenças entre as medianas dos meses de permanência no PES em função da distância domicílio-PES (p = 0,11). CONCLUSÃO: Para um determinado PES privado da cidade do Rio de Janeiro e funcionando de segunda a sábado com livre escolha de horário, a distância domicílio-PES não influenciou na aderência dos participantes. Isso provavelmente se deveu à qualidade do serviço prestado e/ou a ausência de opções mais próximas do local de domicílio dos participantes. (Arq Bras Cardiol. 2012; [online].ahead print, PP.0-0).


BACKGROUND: One of the difficulties in maintaining long-term adherence to exercise is the distance from home to the place of exercise. OBJECTIVE: To determine, for a private supervised exercise program (PSEP), the influence of the home-PSEP distance on adherence. METHODS: We identified 976 individuals and selected 796 who met the inclusion criteria. The home-PSEP distance was obtained by the Google Maps. Adherence was determined by quartiles (months): 1-4, 5-12, 13-36 and more than 36. The clinical conditions were stratified as healthy, obese and/or hypertensive and/or dyslipidemic and/or diabetic patients without coronary disease; coronary artery disease patients and other health problems like cancer, respiratory disease and panic. The home-PSEP distance was divided into (km): up to 1, 1 to 3, 3 to 10 and more than 10. For the statistical analysis, we used the Kruskal-Wallis ANOVA and the chi-square test. RESULTS: Of respondents, 46% lived up to 3 km, 39% lived between 3 and 10 km and about 15% lived more than 10 kilometers from the place of the PSEP. No differences were found between the medians of the months of participation in the PSEP as a function of home-PSEP distance (p = 0.11). CONCLUSION: For a given PSEP in the city of Rio de Janeiro, open from Monday through Saturday with free choice of time, the home-PSEP distance did not influence the adherence of participants. This was probably due to the quality of the service and/or lack of places closer to the participants’ home. (Arq Bras Cardiol. 2012; [online].ahead print, PP.0-0).

RESUMO

OBJECTIVE: To determine the prevalence of overweight and obesity in children attending public and private schools in the urban area of Feira de Santana-BA; to evaluate both the perception of excessive weight gain by guardians and the prevalence of treatment of those children. METHOD: Cross-sectional study with 699 children, whose age ranged from 5 to 9 years old, attending public and private schools of Feira de Santana-BA in 2001. Overweight was defined as body mass index (BMI)> or =85th percentile and obesity as BMI > or =95th percentile both for age and gender. The level of perception of children's excessive weight gain by guardians was evaluated by means of individual interviews. RESULTS: Total prevalence rates were 9.3% for overweight and 4.4% for obesity, without statistically significant difference among age and gender. White ethnic group was related only to overweight. Prevalence for overweight and obesity was, respectively, 6.5% and 2.7% for public schools and 13.4% and 7.0% for private ones. Guardians suspected that 11.7% of the children presented excessive weight gain. Only 11.1% of them were submitted to treatment. A percentage of 22.2% of these treatments were performed by specialized professionals. CONCLUSIONS: The prevalence of overweight and obesity was high and similar to some studies in Brazil; even though excessive weight gain can be recognized by children's guardians, they are not aware of the necessity of treatment.
