Shift work that involves circadian disruption has been highlighted as a likely carcinogenic factor for breast cancer in humans. Also, unhealthy lifestyle habits observed in night work nurses could be causally related to an increase in the incidence of estrogen-positive breast tumours in this population. Assessing baseline risk of breast cancer in nurses is essential. The objective of this study was to analyze the risk of breast cancer that nurses had in relation to their lifestyle and labour factors related to shift work. A cross-sectional descriptive study through a questionnaire about sociodemographic variables, self-perception of health, and working life was designed. The sample consisted of 966 nurses. The relationship between variables was tested. A binary logistic regression and a classification and regression tree were performed. The most significant labour variables in relation to the risk of breast cancer were the number of years worked (more than 16 years; < 0.01; OR = 8.733, 95% CI = 2.811, 27.134) and the total years performing more than 3 nights per month (10 or more years; < 0.05; OR = 2.294, 95% CI = 1.008, 5.220). Also, the nights worked throughout life (over 500; OR = 4.190, 95% CI = 2.118, 8.287) were significant in the analysis. Nurses who had or ever had breast cancer valued their self-perceived health more negatively ( < 0.001) and referred a lower quality of sleep ( < 0.001) than the non-cases nurses. The occupational factors derived from night work could have several impacts on nurses' health and their family-work balance. Promoting healthy lifestyles, informing about shift work risks, and adjusting shift work schedules are critical methods to decrease the possible effects of circadian disruption in nurses.
涉及昼夜节律紊乱的轮班工作已被视为人类患乳腺癌的一个可能致癌因素。此外，夜班护士中观察到的不健康生活习惯可能与该人群中雌激素阳性乳腺肿瘤发病率的增加存在因果关系。评估护士患乳腺癌的基线风险至关重要。本研究的目的是分析护士患乳腺癌的风险与其与轮班工作相关的生活方式和劳动因素之间的关系。通过一份关于社会人口统计学变量、自我健康认知和工作生活的问卷设计了一项横断面描述性研究。样本包括966名护士。对变量之间的关系进行了测试。进行了二元逻辑回归和分类回归树分析。与患乳腺癌风险最显著相关的劳动变量是工作年限（超过16年；<0.01；OR = 8.733，95%CI = 2.811，27.134）以及每月值夜班超过3个晚上的总年数（10年或更长时间；<0.05；OR = 2.294，95%CI = 1.008，5.220）。此外，一生中值夜班的次数（超过500次；OR = 4.190，95%CI = 2.118，8.287）在分析中也具有显著性。患有或曾经患过乳腺癌的护士对其自我感知健康的评价更负面（<0.001），且报告的睡眠质量比未患乳腺癌的护士更低（<0.001）。夜班工作产生的职业因素可能对护士的健康及其家庭 - 工作平衡产生多种影响。促进健康的生活方式、告知轮班工作风险以及调整轮班工作计划是降低昼夜节律紊乱对护士可能产生的影响的关键方法。
