To determine whether repeated infancy-onset lifestyle counselling alters parental smoking and children's exposure to tobacco smoke.
In 1990, 1062 healthy infants were recruited to a randomized, ongoing atherosclerosis prevention trial (STRIP). Intervention families received at least twice a year individualized nutrition and lifestyle counselling. By 1999, 652 8-y-old children continued participation. Exposure to tobacco smoke was evaluated using serum cotinine concentration. Parents' smoking was also assessed using questionnaires and interviews.
Parents' smoking decreased during the study similarly in the intervention and control groups. Of the 8-y-old children, 46% had detectable serum cotinine concentration, suggesting exposure to tobacco smoke during the past few days. All children were non-smokers. Serum cotinine concentrations did not differ between the intervention and control children. Children's cotinine values were highest in the families where either father or both parents were smokers.
Participation in the atherosclerosis prevention trial slightly decreased smoking among the intervention and control parents. However, counselling led to no differences in parental smoking between the two groups, or in exposure of the intervention and control children to tobacco smoke. This study suggests that more detailed and targeted intervention is required to achieve a significant effect on children's tobacco smoke exposure.
确定反复进行的婴幼儿期生活方式咨询是否会改变父母吸烟情况以及儿童接触烟草烟雾的情况。
1990年，1062名健康婴儿被招募到一项正在进行的随机化动脉粥样硬化预防试验（STRIP）中。干预组家庭每年至少接受两次个性化营养和生活方式咨询。到1999年，652名8岁儿童继续参与研究。使用血清可替宁浓度评估接触烟草烟雾的情况。还通过问卷调查和访谈评估父母的吸烟情况。
在研究期间，干预组和对照组父母的吸烟情况均有类似程度的下降。在8岁儿童中，46%的儿童血清可替宁浓度可检测到，这表明在过去几天内接触过烟草烟雾。所有儿童均不吸烟。干预组和对照组儿童的血清可替宁浓度没有差异。在父亲或父母双方吸烟的家庭中，儿童的可替宁值最高。
参与动脉粥样硬化预防试验使干预组和对照组父母的吸烟率略有下降。然而，咨询并未导致两组父母吸烟情况出现差异，也未使干预组和对照组儿童接触烟草烟雾的情况有所不同。这项研究表明，需要更详细、有针对性的干预措施才能对儿童接触烟草烟雾产生显著影响。
