This study investigated the associations between the variables of the theory of planned behavior (TPB), influence of significant others, and smoking intentions and behaviors among adolescents living in rural southern China.
A cross-sectional study was conducted among 2609 students in two junior high schools in rural Shantou, Guangdong province, using a self-administered questionnaire. Logistic regression models were fitted to estimate univariate and adjusted odds ratios and corresponding 95% confidence intervals.
Multivariate analyses showed that having favorable attitudes towards smoking on psychological and social aspects, perceived behavioral control, and having most friends who were current smokers were significantly associated with smoking intentions in the next six months and in the next five years. Having most family members who were current smokers was also significantly related to smoking intention in the next five years. Having favorable attitudes towards smoking on psychological aspect and negative attitudes on physical aspect, perceived support from friends on smoking, and having most friends and senior relatives being current smokers were significantly associated with increased likelihood of ever smoking. Perceived behavioral control and having most friends being current smokers were also significantly associated with regular smoking and smoking in the past 30days.
Our results suggest that the key constructs of the TPB model and friends' smoking behaviors play important roles in accounting for smoking intentions and behaviors among a sample of rural Chinese adolescents.
本研究调查了计划行为理论（TPB）的变量、重要他人的影响与中国南方农村青少年吸烟意图及行为之间的关联。
在广东省汕头市农村地区的两所初中，对2609名学生开展了一项横断面研究，采用自填式问卷。拟合逻辑回归模型以估计单因素和调整后的比值比及相应的95%置信区间。
多变量分析显示，在心理和社会层面上对吸烟持积极态度、感知行为控制，以及大多数朋友为当前吸烟者，与未来六个月及未来五年内的吸烟意图显著相关。大多数家庭成员为当前吸烟者也与未来五年内的吸烟意图显著相关。在心理层面上对吸烟持积极态度且在身体层面上持消极态度、感知到朋友对吸烟的支持，以及大多数朋友和年长亲属为当前吸烟者，与曾经吸烟可能性的增加显著相关。感知行为控制以及大多数朋友为当前吸烟者也与经常吸烟及过去30天内吸烟显著相关。
我们的结果表明，TPB模型的关键构成要素以及朋友的吸烟行为在解释中国农村青少年样本中的吸烟意图和行为方面发挥着重要作用。
