    據European Heart Journal刊登的最新研究文章，童年期暴露在二手煙環(huán)境中可對兒童動脈結構造成不可逆影響。暴露于二手煙環(huán)境可導致兒童動脈壁增厚，增加其今后患心臟病及中風等風險。來自塔斯馬尼亞、澳大利亞及芬蘭的研究人員表示，童年期暴露于父母雙方均吸煙的二手煙環(huán)境中的人群，成年后其血管的老化程度比普通人群高3.3年左右。

    Abstract

    Aim Recent evidence suggests that the exposure of children to their parents' smoking adversely effects endothelial function in **hood. We investigated whether the association was also present with carotid intima-media thickness （IMT） up to 25 years later.

    Methods and results The study comprised participants from the Cardiovascular Risk in Young Finns Study （YFS, n = 2401） and the Childhood Determinants of Adult Health （CDAH, n = 1375） study. Exposure to parental smoking （none, one, or both） was assessed at baseline by questionnaire. B-mode ultrasound of the carotid artery determined IMT in **hood. Linear regression on a pooled dataset accounting for the hierarchical data and potential confounders including age, sex, parental education, participant smoking, education, and ** cardiovascular risk factors was conducted. Carotid IMT in **hood was greater in those exposed to both parents smoking than in those whose parents did not smoke [adjusted marginal means: 0.647 mm ± 0.022 （mean ± SE） vs. 0.632 mm ± 0.021, P = 0.004]. Having both parents smoke was associated with vascular age 3.3 years greater at follow-up than having neither parent smoke. The effect was independent of participant smoking at baseline and follow-up and other confounders and was uniform across categories of age, sex, ** smoking status, and cohort.

    Conclusions These results show the pervasive effect of exposure to parental smoking on children's vascular health up to 25 years later. There must be continued efforts to reduce smoking among **s to protect young people and to reduce the burden of cardiovascular disease across the population.
