To analyze the relation between smoking and passive smoking with heart rate variability parameters in male adolescents.
The sample consisted of 1,152 males, aged 14 and 19 years. Data related to smoking and passive smoking were collected using a questionnaire. RR intervals were obtained by a heart rate monitor, on supine position, for 10 minutes. After collecting the RR intervals, time (standard deviation of all RR intervals, root mean square of the squared differences between adjacent normal RR intervals and the percentage of adjacent intervals over 50ms) and frequency domains (low and high frequency and sympathovagal balance) parameters of heart rate variability were obtained.
No significant differences between smoker and nonsmoker adolescents were observed in heart rate variability parameters (p>0.05). Similarly, heart rate variability parameters did not show significant difference between exposed and not exposed to passive smoking (p>0.05).
Cigarette smoking and passive smoking are not related to heart rate variability in adolescence.
分析男性青少年吸烟及被动吸烟与心率变异性参数之间的关系。
样本包括1152名年龄在14至19岁的男性。使用问卷收集与吸烟和被动吸烟相关的数据。通过心率监测仪在仰卧位获取RR间期,持续10分钟。收集RR间期后,获得心率变异性的时域(所有RR间期的标准差、相邻正常RR间期平方差的均方根以及相邻间期超过50毫秒的百分比)和频域(低频和高频以及交感神经与迷走神经平衡)参数。
吸烟者与不吸烟者青少年在心率变异性参数方面未观察到显著差异(p>0.05)。同样,暴露于被动吸烟和未暴露于被动吸烟的青少年在心率变异性参数上也未显示出显著差异(p>0.05)。
吸烟和被动吸烟与青少年的心率变异性无关。
