背景：体力活动（PA）与成人动态血压（ABP）之间的关系已被证实。这种关联和可能改变它的因素，如肥胖，尚未在青少年中报道。本研究的目的是确定11- 16岁青少年中PA与ABP的关系，并检查肥胖和其他因素的调节作用。方法采用腕动仪对374例青少年进行24 h ABP和PA测定。计算每次血压测量前每5分钟间隔的平均PA与清醒期间的ABP之间的相关性。混合效应模型采用ABP变量作为独立的因变量。除了每次血压前5分钟的PA分数外，体重指数（BMI） z分数和其他变量被添加到模型中作为协变量，并作为与活动的交互项。结果血压测量前5min PA与收缩压（SBP）和舒张压（DBP）的相关系数分别为0.22和0.25。在混合效应分析中，PA每增加1个单位，收缩压增加0.02 mm Hg，舒张压增加0.01 mm Hg，心率增加0.02次/分钟（P< 0.0001）。BMI z-评分较高的患者血压与PA的相关性显著降低（SBP，P< 0.001， DBP，P= 0.027）。青少年性成熟状态改变了PA与收缩压和HR的关系。结论本研究发现PA与ABP测量值相关。这些关联会受到肥胖状况和其他变量的影响。认识到这些关联可以改善对ABP测量结果的解释。Am J Hypertens 2007；20: 140-147©2007美国高血压杂志
BackgroundThe association between physical activity (PA) and ambulatory blood pressure (ABP) is documented in adults. This association and factors that may modify it, such as obesity, have not been reported in adolescents. The aims of this study were to determine the association of PA with ABP in 11- to 16-year-old adolescents, and to examine the modifying effects of obesity and other factors.MethodsData on 24-h ABP and PA were obtained from 374 adolescents using the wrist actigraph. Correlations between average PA for every 5-min interval preceding each BP measurement and ABP were calculated during the awake period. Mixed-effects models were used with ABP variables as separate, dependent variables. In addition to PA scores for 5 min preceding each BP, body mass index (BMI) z-score and other variables were added to the models as covariates and as interaction terms with activity.ResultsCorrelations of PA for 5 min preceding BP measurements were 0.22 and 0.25 for systolic blood pressure (SBP) and diastolic blood pressure (DBP) respectively. In mixed-effects analysis, each 1-unit increase in PA was associated with an increase in SBP of 0.02 mm Hg, in DBP of 0.01 mm Hg, and in HR of 0.02 beat/min (P< .0001). The association of BP with PA was significantly less for those with higher BMI z-scores (SBP,P< .001, DBP,P= .027). The associations of PA with SBP and HR were modified by sexual maturation status of the adolescents.ConclusionsThis study found that PA is associated with ABP measurements. These associations are modified by obesity status and other variables. Recognizing these associations may improve the interpretation of ABP measurements.
