The purpose of this study was to investigate the effects of exercise on BP in university professors during teaching and sleeping hours. Methods: Twelve normotensive professors (42.2 ± 10.8 years, 74.2 ± 11.2 kg, 172.8 ± 10.4 cm, 20.1% ± 6.7% body fat) randomly underwent control (CONT) and exercise (EX30) sessions before initiating their daily activities. EX30 consisted of 30 minutes of cycling at 80%–85% of heart rate reserve. Ambulatory BP was monitored for 24 hours following both sessions. Results: BP increased in comparison with pre-session resting values during teaching after CONT (P < 0.05) but not after EX30. Systolic, diastolic, and mean arterial BP showed a more pronounced nocturnal dip following EX30 (approximately -14.7, -12.7, and -9.6 mmHg, respectively) when compared with CONT (approximately -6, -5 and -3 mmHg). Conclusion: Exercise induced a BP reduction in university professors, with the main effects being observed during subsequent teaching and sleeping hours. Keywords: post-exercise blood pressure, aerobic exercise, activities of daily livin

A gravidez na adolescência é um problema de saúde pública, podendo trazer consequências negativas para a adolescente, sua família e para o concepto/recém-nascido. Objetivos: Identificar diferenças entre as características sociodemográficas e reprodutivas das mães adolescentes com parto a termo e com parto pré-termo, no Espírito Santo em 2007. Metodologia: Estudo retrospectivo quantitativo. Os dados foram coletados no Sistema de Informação de Nascidos Vivos, sendo realizada análise descritiva de 9.841 Declarações de Nascidos Vivos. A relação entre a variável dependente (termo) e fatores foi testada pelo teste exato de Fisher, com á=0,05. Os resultados evidenciaram que as diferenças nas características das mães adolescentes com parto a termo e pré-termo ocorreram nas seguintes variáveis: idade entre 10 a 14 anos (p=0,016), estado civil casada (p=0,014), número de consultas pré-natais quando insuficientes (p=0,000) e gestação dupla (p=0,000). Houve maior incidência de partos prematuros no Sistema Único de Saúde (p=0,000).<br>El embarazo en la adolescência es un problema de salud pública, que puede traer consecuencias negativas para la adolescente, su familia y para el concepto/recién-nacido.
