Prevalence of dyslipidemia in individuals physically active during childhood, adolescence and adult age.

BACKGROUND: The prevalence of dyslipidemia is increasing in many parts of Brazil, but it is yet unclear how much exercise is needed to attain beneficial effects on plasma lipoprotein levels. OBJECTIVE: The study analyzed eight cities of the state of São Paulo, the association between the continued practice of physical exercise throughout life and the occurrence of dyslipidemia in adulthood. METHODS: Cross-sectional study involving 2,720 adults, of both sexes, living in eight cities of the state of São Paulo. Through household interviews, the presence of dyslipidemia was self-reported and physical exercise practice was assessed in childhood (7-10 years), adolescence (11-17 years) and adulthood (leisure activities). In the statistical analysis, multivariate models were created using binary logistic regression. RESULTS: The prevalence of dyslipidemia was 12.2% (95%CI: 11.1% -13.5%) and there was no difference between cities (p = 0.443). Women (p = 0.001) and obese individuals (p = 0.001) had a higher rate of dyslipidemia. Current practice of physical exercise was not associated with the presence of dyslipidemia ([≥ 180 minutes per week] p = 0.165); however, physical exercise, both in childhood (p = 0.001) and adolescence (p = 0.001) was associated with a lower incidence of the disease. Physically active adults in all three stages of life were 65% less likely to report dyslipidemia (OR = 0.35 [0.15 to 0.78]). CONCLUSION: The continued practice of physical exercise throughout life was associated with a lower incidence of dyslipidemia in adults in the State of São Paulo.

Indicadores cardiovasculares em repouso e durante um teste incremental em jovens do sexo masculino / Cardiovascular indicators at rest, and during an incremental test in young males

O presente estudo comparou valores de glicemia, frequência cardíaca em repouso e durante exercício, além da composição corporal entre hipertensos e normotensos. A amostra foi composta por 32 jovens do sexo masculino, com média de idade de 22,6 anos. Inicialmente, aferiu-se a pressão arterial, para divisão em dois grupos: hipertensos e normotensos. Posteriormente foram mensurados, glicemia em jejum, impedância bioelétrica, antropometria, e a frequência cardíaca no repouso, durante o teste de esforço máximo e na fase de recuperação. A análise estatística foi composta pelo teste t- Student e análise de variância para medidas repetidas two-way, entre os grupos. O valor de significância adotado foi p = 0,05. Os dados analisados mostraram que indivíduos hipertensos apresentam maiores índices metabólicos e valores hemodinâmicos do que indivíduos normotensos, sendo estes indicadores de risco cardiovascular.

The present study compared blood glucose levels, heart rate (HR) at rest and during exercise, besides body composition between hypertensive and normotensive individuals. The sample consisted of 32 young males with an average age of 22.6 years. Initially, the blood pressure was measured to split the sample into two groups: hypertensive and normotensive. Subsequently, fasting blood glucose, bioelectrical impedance, anthropometry, and resting heart rate, heart rate during maximal effort test and recovery phase were measured. Statistical analysis was composed of a Student t test and two-way repeated measures analysis. The significance adopted was p = 0.05. The analyzed data showed that hypertensive patients have higher metabolic rates and hemodynamic values than normotensive individuals, which are indicators of cardiovascular risk.

Aptidão física, história familiar e ocorrência de hipertensão arterial, osteoporose, doenças metabólicas e cardíacas entre mulheres / Physical fitness, family history and occurrence of arterial hypertension, osteoporosis, metabolic and cardiac diseases among women

A interação entre a atividade física e o genótipo no desenvolvimento de doenças não é muito clara. Avaliar a aptidão física em mulheres e estabelecer a sua associação com a história pessoal/familiar de doenças crônicas. Foram avaliadas 133 mulheres, com idade entre 21 anos e 81 anos (58+ou-12 anos), todas participantes do programa intitulado "saúde preventiva" da cidade de presidente prudente (SP). Para a coleta de dados, utilizou-se um questionário de morbidades referidas (hipertensão arterial, osteoporose, doenças metabólicas e cardíacas)...
