尽管肥胖与癌症发展之间存在密切联系，但个人不太可能将肥胖视为癌症的风险因素，而不是家族史。癌症家族史已被证明会影响患癌症的风险，但目前尚不清楚超重是否会影响癌症风险的认知。这项研究的目的是检查绝对和相对的风险认知癌症的体重状况。横断面数据来自美国国家癌症研究所的2011年健康信息全国趋势调查（n= 2585）。评估了人口统计学、人体测量学数据、癌症家族史、健康行为以及绝对和相对癌症风险感知。体重和家族史对绝对和相对癌症风险认知的影响通过加权描述性和logistic回归分析进行分析。22.8和28.6%的受试者报告说，他们非常不可能/不太可能在他们的一生中患癌症（绝对风险），并与其他人相比，他们的年龄（相对风险），分别。研究结果表明，有和没有癌症家族史的人之间的风险认知存在差异（p< 0.0001）。尽管按家族史分层，但BMI类别之间的绝对癌症风险感知没有显着差异。与健康体重受试者相比，肥胖受试者更可能具有增加的癌症相对风险感知（p= 0.0066）;当按家族史分层时，这种关联仍然显著（p= 0.0161）。教育个人，特别是那些超重/肥胖的人，关于超重对癌症风险的影响，可以提高风险的准确性，并通过体重管理促进癌症风险的降低。
Despite the strong link between obesity and cancer development, individuals are less likely to identify obesity as a risk factor for cancer than family history. Family history of cancer has been documented to influence perceived risk of developing cancer, yet it is unclear if excess weight impacts cancer risk perceptions. The purpose of this study was to examine absolute and relative risk perceptions for cancer by weight status. Cross-sectional data were obtained from the National Cancer Institute’s 2011 Health Information National Trends Survey (n= 2585). Demographics, anthropometric data, family history of cancer, health behaviors, and absolute and relative cancer risk perceptions were evaluated. The effect of weight and family history on absolute and relative cancer risk perceptions was analyzed through weighted descriptive and logistic regression analyses. 22.8 and 28.6 % of subjects reported that they were very unlikely/unlikely to develop cancer in their lifetime (absolute risk) and when compared to others their age (relative risk), respectively. Findings indicated differences in risk perceptions between those with and without a family history of cancer (p< 0.0001). No significant differences were found between BMI categories for absolute cancer risk perceptions despite stratification by family history. Obese subjects were more likely to have an increased relative risk perception of cancer compared to healthy weight subjects (p= 0.0066); this association remained significant when stratified by family history (p= 0.0161). Educating individuals, especially those who are overweight/obese, about the impact of excess weight on cancer risk may improve risk accuracy and promote cancer risk reduction through weight management.
