The aim of this study was to verify the relation between body mass index (BMI) and sitting time in a sample of 4,091 Azorean men. BMI was calculated from self-reported weight and height. Total physical activity (PA) time and total sitting time were assessed with the IPAQ (short version). Linear Regression analysis showed that total sitting time (hours/day) was positively associated with BMI (B = 0.078; p < 0.001) after adjustments for age, meal frequency, alcohol and tobacco consumptions, island of residence, education level and total PA time. Although the cross sectional design precludes us from establishing causality, our findings emphasize the importance of reducing sedentary behavior to decrease the risk of obesity.
本研究旨在验证 4091 名亚速尔男性样本中体重指数 (BMI) 与坐姿时间之间的关系。BMI 通过自我报告的体重和身高计算得出。总体力活动 (PA) 时间和总坐姿时间使用 IPAQ(短版)进行评估。线性回归分析显示,在校正年龄、进餐频率、酒精和烟草消费、居住岛屿、教育水平和总 PA 时间后,总坐姿时间(小时/天)与 BMI 呈正相关(B = 0.078;p < 0.001)。尽管横断面设计使我们无法确定因果关系,但我们的研究结果强调了减少久坐行为以降低肥胖风险的重要性。
