The present study aimed to verify the prevalence and association of sedentary behavior and its breaks with obesity and cardiovascular risk factors in teaching professionals. The sample was composed by 245 public school teachers (186 women and 59 men), with a mean age of 45 yr. Sedentary behavior was evaluated by self-reported screen time in different devices (television, computer, cellphone/tablet), and sedentary breaks at work and leisure were assessed by a Likert scale (never, rarely, sometimes, often, always). Cardiovascular risk factors (overweight/obesity, abdominal obesity, blood pressure, and heart rate) were objectively collected by trained individuals in the work environment of the teachers. Logistic Binary Regression models were adjusted for confounding factors (age, sex, and socioeconomic status). The prevalence of sedentary behavior was 55.3% in the sample. High sedentary behavior was associated to abdominal obesity (OR=2.21 [CI=1.23–3.97]). No association was observed between sedentary breaks at work and independent variables, however teachers with high sedentary breaks at leisure time were less likely to present high blood pressure (OR=0.58 [CI=0.32–0.98]). In conclusion, high sedentary behavior was associated with abdominal obesity, and high sedentary breaks in leisure time were associated to lower chances of high blood pressure among public school teachers.

本研究旨在验证专业人士久坐行为及其与肥胖和心血管危险因素的关系及其发生率。样本由245名公立学校教师（186名女性和59名男性）组成，平均年龄为45岁。久坐行为通过自我报告的屏幕时间在不同设备（电视，计算机，手机/平板电脑）上进行评估，而工作和休闲时的久坐休息时间则用李克特量表进行评估（从不，很少，有时，经常，总是）。心血管危险因素（超重/肥胖，腹部肥胖，血压和心率）是由受过训练的人员在老师的工作环境中客观地收集的。Logistic二元回归模型针对混杂因素（年龄，性别和社会经济地位）进行了调整。样本中久坐行为的患病率为55.3％。久坐的行为与腹部肥胖有关（OR = 2.21 [CI = 1.23–3.97]）。在工作中的久坐时间和自变量之间没有相关性，但是，在闲暇时间久坐的教师出现高血压的可能性较小（OR = 0.58 [CI = 0.32–0.98]）。总之，久坐的行为与腹部肥胖有关，久坐的休息时间多与公立学校教师患高血压的机会降低有关。但是，闲暇时间久坐的教师出现高血压的可能性较小（OR = 0.58 [CI = 0.32–0.98]）。总之，久坐的行为与腹部肥胖有关，久坐的休息时间多与公立学校教师患高血压的机会降低有关。然而，闲暇时间久坐的教师出现高血压的可能性较小（OR = 0.58 [CI = 0.32–0.98]）。总之，久坐的行为与腹部肥胖有关，久坐的休息时间多与公立学校教师患高血压的机会降低有关。
