The aim of this study was to determine whether high blood pressure (HBP) is associated with sedentary behavior in young people even after controlling for potential confounders (gender, age, socioeconomic level, tobacco, alcohol, obesity and physical activity).
In this epidemiological study, 1231 adolescents were evaluated. Blood pressure was measured with an oscillometric device and waist circumference with an inextensible tape. Sedentary behavior (watching television, computer use and playing video games) and physical activity were assessed by a questionnaire. We used mean and standard deviation to describe the statistical analysis, and the association between HBP and sedentary behavior was assessed by the chi-squared test. Binary logistic regression was used to observe the magnitude of association and cluster analyses (sedentary behavior and abdominal obesity; sedentary behavior and physical inactivity).
HBP was associated with sedentary behaviors [odds ratio (OR) = 2.21, 95% confidence interval (CI) = 1.41-3.96], even after controlling for various confounders (OR = 1.68, CI = 1.03-2.75). In cluster analysis the combination of sedentary behavior and elevated abdominal obesity contributed significantly to an increased likelihood of having HBP (OR = 13.51, CI 7.21-23.97).
Sedentary behavior was associated with HBP, and excess fat in the abdominal region contributed to the modulation of this association.
本研究旨在确定即使在控制了潜在混杂因素（性别、年龄、社会经济水平、烟草、酒精、肥胖和身体活动）之后，高血压（HBP）是否与年轻人的久坐行为相关。
在这项流行病学研究中，对1231名青少年进行了评估。使用示波装置测量血压，用不可拉伸的卷尺测量腰围。通过问卷调查评估久坐行为（看电视、使用电脑和玩电子游戏）和身体活动情况。我们用均值和标准差来描述统计分析结果，并用卡方检验评估HBP与久坐行为之间的关联。采用二元逻辑回归来观察关联程度，并进行聚类分析（久坐行为与腹部肥胖；久坐行为与身体不活动）。
即使在控制了各种混杂因素之后，HBP仍与久坐行为相关[比值比（OR）=2.21，95%置信区间（CI）=1.41 - 3.96]（OR = 1.68，CI = 1.03 - 2.75）。在聚类分析中，久坐行为与腹部肥胖增加的组合显著增加了患HBP的可能性（OR = 13.51，CI 7.21 - 23.97）。
久坐行为与HBP相关，腹部过多脂肪对这种关联起到了调节作用。
