Current evidence on the health effects of passive smoking on childhood blood pressure is limited and inconsistent. We investigated the associations between exposure to parental smoking and blood pressure in children and adolescents.
A cross-sectional analysis was performed in a national sample of 42,745 children and adolescents (50.2% boys) aged 7-18 years from seven provinces in China. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured. Information on parental smoking was collected through questionnaire. Multivariable linear regression and logistic regression was used to investigate the associations of parental smoking with blood pressure and prevalent hypertension, respectively.
The reported parental smoking rates were 49.7 and 50.2% in boys and girls, respectively. After adjustment for a range of potential confounders, exposure to parental smoking was associated with 0.44 [95% confidence interval (CI): 0.16, 0.72] mmHg and 0.26 (95% CI: 0.04, 0.47) mmHg higher SBP and DBP in girls. Girls exposed to parental smoking were also more likely to have hypertension compared with those without exposure (odds ratio = 1.11, 95% CI: 1.02, 1.20). No significant associations were found in boys.
Exposure to parental smoking was associated with increased blood pressure and higher prevalence of hypertension in girls, but not in boys. Urgent strategies are needed for the promotion of smoking-free environment, especially for children and adolescents.
目前有关被动吸烟对儿童血压影响的健康证据有限且不一致。我们研究了父母吸烟与儿童和青少年血压之间的关系。
在中国七个省份进行了一项全国性的 42745 名 7-18 岁儿童和青少年（50.2%为男孩）的横断面分析。测量了收缩压（SBP）和舒张压（DBP）。通过问卷收集了父母吸烟的信息。多变量线性回归和逻辑回归分别用于研究父母吸烟与血压和高血压患病率之间的关系。
男孩和女孩的父母吸烟报告率分别为 49.7%和 50.2%。在校正了一系列潜在的混杂因素后，暴露于父母吸烟与女孩的 SBP 和 DBP 分别升高 0.44 [95%置信区间（CI）：0.16，0.72] mmHg 和 0.26（95% CI：0.04，0.47）mmHg 相关。与没有暴露的女孩相比，暴露于父母吸烟的女孩也更容易患高血压（比值比=1.11，95%CI：1.02，1.20）。在男孩中未发现显著相关性。
暴露于父母吸烟与女孩的血压升高和高血压患病率升高有关，但在男孩中则没有。需要采取紧急策略来促进无烟环境，特别是针对儿童和青少年。
