The present report analyzes the relationship between physical activity and blood pressure in 1341 school children aged 7-14 years (girls = 598, boys = 743) participating in a screening for cardiovascular risk factors that took place in the suburban area of Naples. During the baseline examination, systolic (SBP) and diastolic (DBP) blood pressure, height, weight, and resting pulse rate (PR) were measured. The Harvard-Modified Step Test was also performed in order to score both a crude recovery index (RI) and an index corrected for the initial resting pulse rate (RI-PR) used as measures of the level of habitual physical activity. Significant differences have been found between the quartiles of distribution of both the crude recovery index and the corrected index in girls and boys with regard to systolic blood pressure but not diastolic. In both sexes, better responders to the Harvard-Modified Step Test showed on the average lower systolic blood pressure than poorer responders. In boys, the inverse association between systolic blood pressure and the recovery index was independent of the effect of age, body mass index, height, and resting pulse rate, while in girls the same association did not reach statistical significance. Our results support the hypothesis that systolic blood pressure is independently related to the level of habitual physical activity in children.
本报告分析了1341名7至14岁学童（女孩598名，男孩743名）的身体活动与血压之间的关系，这些学童参与了在那不勒斯郊区进行的心血管危险因素筛查。在基线检查期间，测量了收缩压（SBP）、舒张压（DBP）、身高、体重和静息脉搏率（PR）。还进行了哈佛改良台阶试验，以便得出粗略恢复指数（RI）和针对初始静息脉搏率校正的指数（RI-PR），作为习惯性身体活动水平的衡量指标。在女孩和男孩中，就收缩压而言，粗略恢复指数和校正指数的分布四分位数之间存在显著差异，但舒张压方面没有。在两性中，对哈佛改良台阶试验反应较好者的平均收缩压低于反应较差者。在男孩中，收缩压与恢复指数之间的负相关独立于年龄、体重指数、身高和静息脉搏率的影响，而在女孩中，相同的关联未达到统计学显著性。我们的结果支持这样的假设，即收缩压与儿童习惯性身体活动水平独立相关。
