We examined whether personality traits and parental education are associated with smoking initiation in a sample of Spanish secondary school students. Participants, taken from the ITACA study (842 adolescents aged 14-15 years), completed a questionnaire assessing personality traits of the Five Factor Model, smoking behaviours and parental education. Multinomial logistic regression models controlling for age and sex were used to determine the independent associations and interactions of personality traits and parental education with risk of ever trying smoking, as well as with being a regular smoker in adolescence. Higher conscientiousness was related to a lower chance of trying smoking at least once (OR = 0.57, 95% CIs = 0.46, 0.71) as well as being a regular smoker (OR = 0.39, 95% CIs = 0.27, 0.55). Higher emotional instability (neuroticism) was associated with higher risk of being in either smoking category (OR = 1.33, 95% CIs = 1.10, 1.60 and OR = 1.76, 95% CIs = 1.31, 2.35, respectively). Higher extraversion was also associated with a higher risk of both types of smoking behaviour (OR = 1.38, 95% CIs = 1.12, 1.70 and OR = 2.43 (1.67, 3.55, respectively). Higher parental education was significantly related to lower risk of being a regular smoker (OR = 0.70, 95% CIs = 0.54, 0.89), but not with trying smoking in the past. Finally, we found no evidence of the interactions between adolescents' personality and parental education in predicting adolescent smoking behaviours. We conclude that personality factors and parental education are important and independent factors associated with smoking behaviour in adolescents.
我们在一个西班牙中学生样本中研究了人格特质和父母教育程度是否与开始吸烟有关。参与者来自ITACA研究（842名14 - 15岁的青少年），他们完成了一份问卷，评估五因素模型的人格特质、吸烟行为和父母教育程度。使用控制年龄和性别的多项逻辑回归模型来确定人格特质和父母教育程度与曾经尝试吸烟的风险以及在青少年时期成为经常吸烟者之间的独立关联和相互作用。较高的尽责性与至少尝试吸烟一次的较低可能性（比值比[OR]=0.57，95%置信区间[CIs]=0.46，0.71）以及成为经常吸烟者（OR = 0.39，95% CIs = 0.27，0.55）相关。较高的情绪不稳定性（神经质）与处于任何一种吸烟类别中的较高风险相关（分别为OR = 1.33，95% CIs = 1.10，1.60和OR = 1.76，95% CIs = 1.31，2.35）。较高的外向性也与两种吸烟行为类型的较高风险相关（分别为OR = 1.38，95% CIs = 1.12，1.70和OR = 2.43，95% CIs = 1.67，3.55）。较高的父母教育程度与成为经常吸烟者的较低风险显著相关（OR = 0.70，95% CIs = 0.54，0.89），但与过去尝试吸烟无关。最后，我们没有发现青少年人格和父母教育程度之间在预测青少年吸烟行为方面存在相互作用的证据。我们得出结论，人格因素和父母教育程度是与青少年吸烟行为相关的重要且独立的因素。
