Efeito da participação e do desligamento de programa de mudança no estilo de vida sobre o nível de atividade e aptidão física, percepção de saúde e presença de síndrome metabólica em adultos da comunidade de Botucatu - SP

A busca pela estratégia mais eficaz capaz de prevenir, modificar e controlar fatores de risco e doenças crônicas por meio de mudança no estilo de vida (MEV) tornou-se um grande desafio, além de conseguir a adesão, em longo prazo, e principalmente sem supervisão, aos bons hábitos adquiridos durante a intervenção com MEV. Diante disso, o objetivo do presente estudo foi avaliar o efeito da participação e do desligamento do programa de mudança do estilo de vida sobre nível de atividade e aptidão física, percepção de saúde e presença de Síndrome Metabólica em adultos da comunidade de Botucatu-SP. Estudo do tipo transversal com base na comunidade contou com 153 indivíduos previamente participantes de programa de MEV e alocados em grupos Controle, Adesão e Não-Adesão. As avaliações incluíram medidas antropométricas (peso corporal e estatura para cálculo do índice de massa corporal (IMC), circunferência abdominal, percentual de gordura, massa muscular e índice de massa muscular (IMM)), aptidão física (flexibilidade de tronco (sentar e alcançar) e força de preensão manual (dinamometria)) e nível de atividade física e estado de saúde (IPAQ longo, versão 8). Amostra sanguínea de jejum foi utilizada para análise bioquímica (glicemia, HDL-C e triglicerídios), aferição da pressão arterial (técnica auscultatória) e o diagnóstico da Síndrome Metabólica (SM) seguiu as recomendações do NCEP-ATPIII (2001) com adaptação da glicemia (≥ 100 mg/dL) em três momentos (pré-participação (M0), após intervenção de seis meses (M1) e após desligamento (M2) do programa de MEV). Análise de variância e modelo linear generalizado em medidas repetidas para comparação entre momentos e grupos, qui-quadrado, teste de proporção e modelo de regressão logística com nível de significância de 5%. O programa de MEV...The search for more effective strategy able to prevent, control and modify risk factors and chronic diseases through lifestyle change (LSC) has become a major challenge, beyond to achieving the adherence in long term, especially without supervision, the good habits acquired during the LSC intervention. Thus, the purpose of this study was to evaluate the participation and disconnexion effects of lifestyle change program on physical activity level and fitness, on self-perceived health and metabolic syndrome presence in adults from Botucatu-SP’s community. Cross-sectional study of community-based had 153 subjects previously LSC program participants and allocated in Control, Adherence and Non-Adherence. The assessments included anthropometric measurements (weight and height to calculate body mass index (BMI), waist circumference, fat percentage, muscle mass and muscular mass index (MMI)), fitness (trunk flexibility (sit and reach) and handgrip strength (dynamometry)) and physical activity level and health status (IPAQ long version 8). Fasting blood sample was used for biochemical analysis (glucose, HDL-C and triglycerides), blood pressure measurement (auscultatory technique) and metabolic syndrome (MetS) diagnosis followed the NCEP-ATPIII (2001) recommendations with glucose adaptation (≥ 100 mg / dL) in three moments (pre-participation (M0), six months after intervention (M1) and after LSC program disconnexion (M2)). Variance analysis and generalized linear model for repeated measures to compare moments and groups, chi-square and proportions test and logistic regression model with 5% significance level. The LSC program significantly reduced work and housework physical activity, poor health perception and low physical activity level and increased leisure physical activity and flexibility, beyond to attenuate...

Diagnóstico do nível de atividade física de adultos cadastrados na estratégia de saúde da família de Rubião Junior, Botucatu, SP

Epidemiologicamente, os níveis de atividade física relacionam-se inversamente com morbidade e mortalidade por doenças crônicas não transmissíveis. Fatores ambientais e comportamentais modulam a prevalência do sedentarismo, estado em que se enquadra grande parte da população brasileira. O objetivo do presente estudo foi diagnosticar os determinantes do nível de atividade física de amostra populacional em Estratégia de Saúde da Família (Rubião Jr., Botucatu-SP). Foram avaliados 394 adultos (21,8%) que procuraram a unidade no período de março/2006 a setembro/2007. Após triagem médica e formalização ética, participaram de entrevista com profissionais e forneceram dados demográficos, socioeconômicos e respostas aos questionários de atividade física cotidiana (IPAQ, versão 8, forma longa) e habitual (Baecke) e submeteram-se às avaliações de peso, estatura, cálculo índice de massa corporal (IMC- kg/m2) e circunferência abdominal (CA), de flexibilidade de tronco (FLEX - banco de Wells) e de força de preensão manual (FPM - dinamometria). Numa subamostra de 31 indivíduos avaliaram-se o número de passos em atividade física de lazer (AFL - pedômetros), capacidades funcional (TC6 - teste caminhada de seis minutos) e cardiorrespiratória (VO2máx.- protocolo de Balke). Para análise estatística usou-se análise de variância, de componentes principais e fatorial, teste de Tukey, “t” (Student), correlação (Spearman) e regressão logística no programa SAS for Windows (9.1) com p< 0,05. A amostra foi predominantemente feminina (70,8%), de indivíduos com menos de 60 anos (69,3%), casados (67,7%), com primeiro grau incompleto (77,1%), renda familiar até dois salários mínimos (59,4%) e percepção de saúde regular/ruim (66%). Sobrepeso, obesidade e hiperadiposidade abdominal atingiram respectivamente, 38,8%, 38,5% e 65,9% da amostra. A inaptidão física foi maior na FLEX (77,2%) do que na FPM (48,4%).Physical inactivity is related to morbidity and mortality and predominates at most of this country adult population. Environmental and behavioral components are major leading factors to physical inactivity. This study aimed to discriminate the importance of demographic, socioeconomic, anthropometric and physical capacity factors on physical activity levels in a population assisted in a Health-Family Public Strategy (HFS). The sample included 394 adults (≥ 35 years-old – 21.8% of universe) that looked for the HFS (Rubião Jr., Botucatu, SP) during the March/2006-September/2007 period and were in accordance with the ethical requirements as well as physically capable for physical exercises. They were interviewed face to face by a physical educator and answered questions regarding demographic, socioeconomic and physical activity recent (IPAQ 8, long form) and habitual (Baecke score) activities subjects. Additionally, they were all assessed anthropometrically for body weight (BW) and height (H), body mass index (BMI) calculation (kg/m2) and waist circumference (WC). The physical capacity evaluation included trunk flexibility (FLEX – Wells bench), handgrip strength (HGS– dynamometry) and, in a sub-sample of 31 subjects, the 60-minute walking steps (AFL – pedometers), six-minute walking test (6MWT – GPS accelerometers) and cardiorrespiratory index in an electrical treadmill (VO2max. – Balke protocol). The statistical analysis (p<0.05) included ANOVA, main components and factorial, Tukey or “t” (Student) tests, correlation (Spearman) and logistic regression between variables using SAS for Windows (9.1) program. The studied sample was predominantly female subjects (70.8%), aging less than 60 yrs-old (69.3%), married (67.7%), with unaccomplished first educational grade (77.1%), family income lower than two-minimal salaries (2MS - 59.4%) and self-reported health status as poor/regular (66%). Overweight (38.8%) and obesity (38.5%).Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

Efeito de um mês de destreinamento sobre a aptidão física relacionada à saúde em programa de mudança de estilo de vida

Physical exercise induces hemodynamic/ventilatory and neuromuscular adaptations that can be reverted with interruption of the training program. The aim of the present study was to evaluate the effect of detraining on physical fitness related to health. Forty-four healthy subjects, both male and female, aged 57.6±8.9 years performed the 'Mexa-se Pró-Saúde' protocol with nutritional orientation and supervised physical exercises for nine months. The program consisted of aerobic, localized muscular endurance and flexibility exercises, with duration 80 minutes/session, five days/week. Only subjects who participated in the program for more than three days/week have been selected. The detraining period was one month. Weight (kg) and height (m) were measured and the body mass index (BMI) calculated. Additionally, motors tests to evaluate the flexibility (FLEX), strength of lower limbs (SLL) and upper limbs (SUL), and maximal oxygen uptake (VO2máx) were conducted in the beginning of the study (MI), after nine months of practicing (MT) and after detraining period (MD). ANOVA (p<0.05) and Tukey test to show the difference between groups when it evidence were used for statistical treatment. The results showed that the gains of 22% and 7% on SLL and VO2máx respectively, obtained with the training, have not changed during the detraining period; however, the flexibility gain of 8% returned back to baseline after the detraining period. BMI and SUL did not change during the study. Although the lower limbs strength gains and maximal oxygen uptake obtained have been kept, one month of detraining was enough for losing the flexibility acquired

Physical fitness and associations with anthropometric measurements in 7 to 15-year-old school children

Objective: To analyze associations between health-related physical fitness and the anthropometric and demographic indicators of children from three elementary schools in Botucatu, SP, Brazil.Methods: The sample for this cross-sectional study was composed of 988 students, recruited from the second to ninth grades (an age range of 7 to 15 years). The children underwent anthropometric assessment (weight, height, waist circumference and tricipital and subscapular skin folds) and were tested for health-related physical fitness (flexibility: sit and reach test; abdominal strength/resistance: 1-minute abdominal test; and aerobic resistance: 9-minute running/walking test). Data were analyzed using descriptive statistics plus Student's t test, the chi-square test or Fisher's exact test and logistic regression with a significance level of 5%.Results: The physical fitness levels observed were significantly influenced by age (all levels), sex (abdominal strength/resistance), obesity (all levels), body adiposity (flexibility, abdominal strength/resistance) and abdominal adiposity (abdominal strength/resistance and aerobic resistance). Females were more prone to be unfit in abdominal strength/resistance. Both obesity and excessive abdominal adiposity predisposed children to be unfit in abdominal strength/resistance and aerobic resistance. Excess body adiposity increased the likelihood of poor trunk flexibility.Conclusions: Unhealthy physical fitness levels were related to female sex, obesity and excessive abdominal adiposity. Implementing programs designed to effect lifestyle changes to achieve physical fitness and healthy nutrition in these schools would meet the objectives of promoting healthy body weight and increased physical fitness among these schoolchildren.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Treating Blood Hypertension in a Brazilian Community: Moving from Reactive Homeostatic Model to Proactive Allostatic Healthcare

The responsiveness of hypertensive subjects to different types of physical exercises and length of intervention, has been investigated in samples of our dynamic cohort study (&ldquo;Move for Health&rdquo; program) based on spontaneous demand for healthy lifestyle with supervised exercises and dietary counseling. After clinical selection and baseline assessments they were spontaneously assigned to exercise protocols of strength (PAc) isolated or combined with endurance (walking) exercises (PMi) daily or in alternated days(PMiA), hydrogymnastics(PHy) and tread mill high- intensity exercises(PHit), applied during 10(experiment 1) and 20(experiment 2) weeks of intervention. Baseline demographic, socioeconomic, anthropometric and physical activity and fitness characteristics were similar among protocols. Ten-week training improved VO2max. Similarly in all protocols while hand grip increased only in PAc. In average, there was a 16% reduction rate of hypertension rate from baseline with both, SBP and DBP, reduced by PHy and only SBP by the PMi. After adjustments hypertension was more reduced by PAc, PMi and PHy. In the 20-week experiment, higher SBP was similarly reduced by PAc or PMiA and DBP by PMiA, after adjustments. Hence, so far, our generated data suggest physical exercises as an effective tool for hypertension reduction, from 10 weeks to 3 year-long supervised protocols composed by surface or aquatic activities with strength or endurance exercises. PAc takes longer and short-period responsiveness can be achieved by either combined (strength-endurance) or hydrogymnastic exercises. Thus, exercise training is a time-and type-dependent tool, feasible, costless and scientific-based rheostatic-allostatic alternative for the current &ldquo;sick-care&rdquo; drug-dependent homeostatic approach to hypertension med care
