'Overweight and obesity' is the second biggest preventable cause of cancer after smoking. In 2018, Cancer Research UK launched an awareness raising campaign about the link between overweight and obesity and cancer risk. This study aimed to evaluate the reach and impact of the campaign.
This study was a repeated cross-sectional online survey.
The campaign consisted of six elements including the main message that 'Obesity is a cause of cancer'. UK adults and Members of Parliament (MPs) were surveyed before the campaign (W1; n = 2124 and n = 151), 1 month (W2; n = 2050 and n = 151) and 3 months after the campaign (W3; n = 2059 and MPs not surveyed). Outcome measures were campaign reach, awareness of overweight and obesity as risk factors for cancer, attitudes towards individuals who are overweight or obese, support for policies to reduce obesity and reactions to the campaign.
Overall, 76.2% of MPs and just under half of the public (47.5% in W2 and 36.8% in W3) reported having seen the campaign. Unprompted awareness of obesity as a risk factor increased among the public from 17.1% at W1 to 43.3% in W2 (odds ratio 3.71, 95% confidence interval 3.18-4.33) and 30.3% in W3 (odds ratio 2.11, 95% confidence interval 1.80-2.47). A similar pattern was seen for prompted awareness and among MPs. There were no consistent changes in attitudes towards overweight individuals or support for policies to reduce obesity.
This evaluation suggests that the campaign achieved the primary objective of increasing awareness of the link between obesity and cancer without increasing negative attitudes towards individuals who are overweight or obese.
超重和肥胖是仅次于吸烟的第二大癌症可预防病因。2018 年，英国癌症研究中心发起了一项提高超重和肥胖与癌症风险之间关联认识的宣传活动。本研究旨在评估该活动的覆盖范围和影响。
这是一项重复的横断面在线调查研究。
该活动由六个部分组成，包括主要信息，即“肥胖是癌症的一个病因”。在活动前（W1；n=2124 和 n=151）、活动后 1 个月（W2；n=2050 和 n=151）和 3 个月（W3；n=2059 和未对议员进行调查），对英国成年人和议员进行了调查。结果衡量标准为活动覆盖范围、超重和肥胖作为癌症风险因素的认知度、对超重或肥胖个体的态度、对减少肥胖政策的支持度以及对活动的反应。
总体而言，76.2%的议员和近一半的公众（W2 时为 47.5%，W3 时为 36.8%）报告称曾看到过该活动。公众对肥胖是一种风险因素的认知度在未提示的情况下从 W1 时的 17.1%增加到 W2 时的 43.3%（优势比 3.71，95%置信区间 3.18-4.33）和 W3 时的 30.3%（优势比 2.11，95%置信区间 1.80-2.47）。议员中也出现了类似的提示后认知度变化。对超重个体的态度或对减少肥胖政策的支持度没有一致的变化。
这项评估表明，该活动实现了提高公众对肥胖与癌症之间关联的认识的主要目标，而没有增加对超重或肥胖个体的负面态度。
