To assess perceptions about potentially modifiable causes of cancer.
An anonymous telephone questionnaire administered to a sample, 20 years and older, randomly selected from telephone directory listings.
Nearly 90% of 438 respondents (68% participation) considered that there were things which people could do to reduce cancer risk. Unprompted, almost two-thirds mentioned nutrition, and more than half suggested "not smoking." Other suggestions included being physically active, and protection from excessive sun exposure. Two-thirds believed they could reduce their own risk, and by interview end this increased significantly to 72%. Half named items which people could consume to reduce risk: more vegetables, fruit or water; less alcohol, fatty foods, and meat. Greatest awareness was of risks from sunburn, secondhand tobacco smoke, sunlamps, eating animal fat, and being overweight, and of the protective effects of eating grains, fruit, and vegetables. Many considered stress, cellular phones, and genetically modified foods as risks, and vitamin and mineral supplements as protective. Few indicated awareness of risks from hepatitis B or alcohol.
Greater public awareness about avoiding tobacco smoking and excessive sun exposure suggests gains from past efforts. To achieve similar awareness for other cancer prevention strategies, and to correct misconceptions, comparable resources and efforts are likely to be required.
评估对癌症潜在可改变病因的认知。
对从电话簿列表中随机抽取的20岁及以上的样本进行匿名电话问卷调查。
438名受访者中近90%(参与率68%)认为人们可以采取一些措施来降低患癌风险。在未被提示的情况下,近三分之二的人提到了营养,超过一半的人建议“不吸烟”。其他建议包括进行体育锻炼以及避免过度暴露在阳光下。三分之二的人认为他们可以降低自身风险,到访谈结束时,这一比例显著上升至72%。一半的人列举了人们可以食用以降低风险的食物:更多的蔬菜、水果或水;更少的酒精、高脂肪食物和肉类。对晒伤、二手烟、太阳灯、食用动物脂肪和超重的风险以及食用谷物、水果和蔬菜的保护作用的认知度最高。许多人认为压力、手机和转基因食品有风险,而维生素和矿物质补充剂有保护作用。很少有人表示意识到乙肝或酒精的风险。
公众对避免吸烟和过度暴露在阳光下的认知度提高,表明过去的努力取得了成效。要使公众对其他癌症预防策略有类似的认知,并纠正误解,可能需要投入相当的资源和努力。
