African American breast cancer survivors experience poor cancer outcomes that may, in part, be remedied by healthy lifestyle choices. Few studies have evaluated the health and lifestyle behaviors of this population. The purpose of this study was to characterize the health and lifestyle habits of African American breast cancer survivors and evaluate the socio-demographic and medical correlates of these behaviors.
A total of 470 African American breast cancer survivors (mean age = 54 years) participated in an online survey. All participants completed measures assessing medical and demographic characteristics, physical activity, and sedentary behavior. Chi-square tests for association, nonparametric tests, and logistic regression models were used to assess associations. All statistical tests were two sided.
Almost half (47%) of the women met the current guidelines for physical activity, almost half (47%) were obese, and many reported having high blood pressure (53%) or diabetes (21%). The prevalence of high blood pressure, diabetes, and high cholesterol increased by age (P<0.001), and obese women had a higher prevalence of high blood pressure (63% vs. 44%) and diabetes (21% vs. 12%) than did non-obese women (all P<0.05). Obese women participated in significantly fewer total minutes of physical activity per week (100 minutes/week) than did non-obese women (150 minutes/week; P<0.05). The number of comorbid conditions was associated with increased odds for physical inactivity (odds ratio = 1.40) and obesity (odds ratio = 2.22).
Many African American breast cancer survivors had chronic conditions that may be exacerbated by poor lifestyle choices. Our results also provide evidence that healthy lifestyle interventions among obese African American breast cancer survivors are urgently needed.
非裔美国乳腺癌幸存者的癌症预后较差，而健康的生活方式选择可能在一定程度上改善这一状况。但目前很少有研究评估这一人群的健康和生活方式行为。本研究的目的是描述非裔美国乳腺癌幸存者的健康和生活习惯，并评估这些行为的社会人口学和医学相关性。
共有 470 名非裔美国乳腺癌幸存者（平均年龄 54 岁）参与了一项在线调查。所有参与者均完成了评估医疗和人口统计学特征、身体活动和久坐行为的测量。使用卡方检验、非参数检验和逻辑回归模型来评估相关性。所有统计检验均为双侧检验。
近一半（47%）的女性符合当前身体活动指南，近一半（47%）为肥胖，许多人报告患有高血压（53%）或糖尿病（21%）。高血压、糖尿病和高胆固醇的患病率随年龄增加而增加（P<0.001），肥胖女性高血压（63%比 44%）和糖尿病（21%比 12%）的患病率高于非肥胖女性（均 P<0.05）。肥胖女性每周的总身体活动分钟数明显少于非肥胖女性（每周 100 分钟比每周 150 分钟；P<0.05）。合并疾病的数量与身体活动不足（比值比=1.40）和肥胖（比值比=2.22）的可能性增加相关。
许多非裔美国乳腺癌幸存者患有慢性疾病，这些疾病可能因不良的生活方式选择而恶化。我们的研究结果还表明，肥胖的非裔美国乳腺癌幸存者急需进行健康生活方式干预。
