BACKGROUNDTo study the association between psychosocial factors and the development of lung cancer.
METHODSCase-control matched study was employed in the study. A standardized life event, social support and defense mechanisms interview was administered respectively. Total 118 lung cancer patients who were diagnosed pathologically were chosen as case group, and 118 matched healthy people were as control group. The pair had the same gender, the same race, and the same occupation, and lived in the same area, and the age difference between the two groups was ±3 years.
RESULTSUnivariate analysis showed that smoking, defect of sleeping, alcohol consuming, smoking and drinking during meal, preserved food consuming, irregularity of life increased the risk of lung cancer development (P < 0.05). The scores of life events, social support had no significant difference between two groups (P > 0.05), but the scores of stress life events was higher in cancer group than that in control group. The immature factors of defense mechanisms in cancer group were higher than those in control group (P < 0.05). Multiple qualified logistic regression showed that smoking and defect of sleeping were the main risk factors of lung cancer genesis.
CONCLUSIONSThere is certain association between psychosocial factors and lung cancer development. The immature defensive factor is the psychosocial factor of lung cancer genesis, and smoking, defect of sleeping, alcohol consuming, smoking and drinking during meal, preserved food consuming, irregularity of life are the risk factors of lung cancer.
