To assess public perceptions of coronary heart disease (CHD) risk factors.
Discrete choice experiment questionnaire.
Six provincial centres in Northern Ireland.
1000 adults of the general public in Northern Ireland.
The general public's perception of CHD risk factors. The effect of having risk factor(s) on that perception.
Two multinomial logit models were created. One was a basic model (no heterogeneity permitted), while the other permitted heterogeneity based on respondents' characteristics. In both models individuals with very high cholesterol were perceived to be at the highest risk of having a coronary event. Respondents who reported having high cholesterol perceived the risk contribution of very high cholesterol to be greater than those who reported having normal cholesterol. Similar findings were observed with blood pressure and smoking. Respondents who were male and older perceived the contribution of age and gender to be lower than respondents who were female and younger.
Respondents with different risk factors perceived such factors differently. These divergent perceptions of CHD risk factors could be a barrier to behavioural change. This brings into focus the need for more tailored health promotion campaigns to tackle CHD.
评估公众对冠心病（CHD）危险因素的认知。
离散选择实验问卷。
北爱尔兰六个省级中心。
1000 名北爱尔兰普通成年人。
公众对 CHD 危险因素的认知。有（有）危险因素对这种认知的影响。
创建了两个多项逻辑回归模型。一个是基本模型（不允许异质性），另一个允许根据受访者的特征进行异质性。在这两个模型中，胆固醇非常高的个体被认为处于发生冠心病事件的最高风险中。报告胆固醇高的受访者认为非常高的胆固醇对风险的贡献大于报告胆固醇正常的受访者。血压和吸烟也有类似的发现。男性和年龄较大的受访者认为年龄和性别对风险的贡献低于女性和年轻的受访者。
有不同危险因素的受访者对这些因素有不同的看法。对 CHD 危险因素的这种不同看法可能是行为改变的障碍。这凸显了需要更有针对性的健康促进活动来解决 CHD 问题。
