BackgroundStudies have shown sodium restriction to have a beneficial effect on blood pressure (BP) of hypertensive patients.ObjectiveTo evaluate the impact of light salt substitution for regular salt on BP of hypertensive patients.MethodsUncontrolled hypertensive patients of both sexes, 20 to 65 years-old, on stable doses of antihypertensive drugs were randomized into Intervention Group (IG - receiving light salt) and Control Group (CG - receiving regular salt). Systolic BP (SBP) and diastolic BP (DBP) were analyzed by using casual BP measurements and Home Blood Pressure Monitoring (HBPM), and sodium and potassium excretion was assessed on 24-hour urine samples. The patients received 3 g of salt for daily consumption for 4 weeks.ResultsThe study evaluated 35 patients (65.7% women), 19 allocated to the IG and 16 to the CG. The mean age was 55.5 ± 7.4 years. Most participants had completed the Brazilian middle school (up to the 8th grade; n = 28; 80.0%), had a family income of up to US$ 600 (n = 17; 48.6%) and practiced regular physical activity (n = 19; 54.3%). Two patients (5.7%) were smokers and 40.0% consumed alcohol regularly (n = 14). The IG showed a significant reduction in both SBP and DBP on the casual measurements and HBPM (p < 0.05) and in sodium excretion (p = 0.016). The CG showed a significant reduction only in casual SBP (p = 0.032).ConclusionsThe light salt substitution for regular salt significantly reduced BP of hypertensive patients.
ObjetivoAvaliar o consumo alimentar e o perfil antropométrico, comparar a composição corporal entre os sexos e analisar a adequação da ingestão alimentar às necessidades de bailarinos profissionais e semiprofissionais.MétodosForam analisados 16 bailarinos de ambos os sexos, com idade entre 20 e 35 anos, de uma companhia de dança contemporânea, de nível internacional, de Goiânia (GO). Foram coletados peso; altura; dobras cutâneas tricipital, peitoral,subescapular, axilar média, suprailíaca, abdominal e da coxa; e dois recordatórios de 24 horas. Para ingestão energética, as recomendações utilizadas foram a do Institute of Medicine, e, para macronutrientes, Institute of Medicine e AmericanCollege of Sports Medicine. Os dados foram digitados no Epi Info 6.04 de analisados no Statistical Package for Social Sciences 18.0. Foram aplicados os testes Shapiro-Wilk, Mann Whitney e Wilcoxon, com nível de significância de 0,05.ResultadosA única medida corporal que diferiu entre os grupos foi, no caso das mulheres, a dobra tricipital, com menor valor no grupo profissional (p=0,03). As dobras cutâneas tricipital e da coxa (p<0,001), peitoral (p=0,007) e suprailíaca (p=0,009)diferiram entre os sexos, sendo maiores entre as mulheres. A ingestão energética foi inferior às necessidades tanto para as mulheres (p=0,01), quanto para os homens (p=0,02).ConclusãoNão houve diferença significativa na composição corporal entre indivíduos do mesmo sexo. A porcentagem de gordura e as dobras cutâneas tricipital, peitoral, suprailíaca e da coxa foram maiores entre as mulheres. Os consumos de energia,carboidratos e proteínas foram inferiores às recomendações.Termos de indexação: Antropometria. Composição corporal. Dança. Ingestão de alimentos. Ingestão de energia.
