The relationship between personality, emotional control and the incidence of female breast cancer

Abstract

Objective: To explore the correlation of personality, emotional control and the risk of female breast cancer. Methods: A convenient sampling of 106 preoperative female patients diagnosed with breast tumor and the subjects were allocated to breast cancer(BC)group(n=49)and breast benign disease(BBD)group(n=57)based on the result of pathological examination after surgery. A no cancer control group(NC)of 49 females were chosen according to the criterion: Age±5years and 1:1 matching with the BC group. All the subjects were measured by Eysenck Personality Questionnaire-Revised short scale for Chinese(EPQ-RSC), Chinese version of the Courtauld Emotional Control Scale(CECS). Results: There was no statistically significance between BC, BBD and NC group in personality traits such as extraversion(P>0. 05), neuroticism(P>0. 05), psychoticism(P>0. 05), and lie(P>0. 05). The emotional control score of angry, anxiety, depression and total score(F=4. 053, 3. 915, 3. 769, 5. 383; P<0. 05)were significantly different among the three groups, BC group was significantly higher than that of BBD and NC group, however there was not statistically different between BBD and NC group. The results of single factor binary logistic regression analysis showed that emotion control(total emotion control and each dimension scores)was risk factors of breast cancer(OR>1, P<0. 05). Conclusion: There is no evidence of an association between the incidence of breast cancer and personality traits such as extroversion and neuroticism; but emotional control may be a risk factor of breast cancer. 目的：探讨女性人格特征、情绪控制与乳腺癌发生危险的关系。方法：使用艾森克人格问卷简式量表中国版(EPQ-RSC)、考陶尔德情绪控制量表中国版(CECS)对诊断为乳腺肿块、拟行手术治疗的106例病人进行调查，手术后根据病理检查结果将病人分为乳腺癌组(BC)49例、乳腺良性疾病组(BBD)57例，并选择同期住院非癌症病人，按照年龄±5岁与BC组进行1：1匹配，得到非癌症对照组(NC)49例进行问卷调查和病例对照分析。结果：BC、BBD和NC 3组间人格特征得分内外向、神经质、精神质和掩饰度比较无统计学差异(P>0.05)；BC、BBD和NC组在情绪控制得分中愤怒抑制、焦虑抑制、抑郁抑制及总分有统计学差异(F=4.053,3.915,3.769,5.383;P<0.05)，BC组明显高于BBD和NC组,而BBD与NC组无统计学差异；二元Logistic回归分析发现，愤怒、焦虑、抑郁抑制及CECS总分与乳腺癌发生的OR值分别为1.109、1.098、1.111、1.050(P<0.05)。结论：内外向等人格特征与乳腺癌的发病不存在相关性，但负性情绪控制可能是乳腺癌发病的危险因素。
