In recent years, behaviourally driven policies such as nudges have been increasingly implemented to steer desired outcomes in public health. This study examines the different nudges and the socio-demographic characteristics and lifestyle behaviours that are associated with public acceptance of lifestyle nudges.
The study used data from the nationwide Knowledge, Attitudes and Practices study (KAP) on diabetes in Singapore. Three types of nudges arranged in increasing order of intrusiveness were examined: (1) information government campaigns, (2) government mandated information and (3) default rules and choice architecture. Acceptance was assessed based upon how much respondents 'agreed' with related statements describing heathy lifestyle nudges. Multivariable linear regressions were performed with socio-demographics and lifestyle behaviours using scores calculated for each nudge.
The percentage of respondents who agreed to all statements related to each nudge were: 75.9% (information government campaigns), 73.0% (government mandated information), and 33.4% (default rules and choice architecture). Respondents of Malay/Others ethnicity (vs. Chinese) were more likely to accept information government campaigns. Respondents who were 18 - 34 years old (vs 65 years and above), female, of Malay/Indian ethnicity (vs Chinese), were sufficiently physically active, and with a healthier diet based on the DASH (Dietary Approach to Stop Hypertension) score were more likely to accept nudges related to government mandated information. Respondents of Malay/Indian ethnicity (vs Chinese), and who had a healthier diet were more likely to accept default rules and choice architecture.
Individuals prefer less intrusive approaches for promoting healthy lifestyle. Ethnicity and lifestyle behaviours are associated with acceptance of nudges and should be taken into consideration during the formulation and implementation of behaviourally informed health policies.
近年来，行为驱动的政策，如“助推”，已被越来越多地用于引导公共卫生领域的预期结果。本研究考察了不同的助推措施，以及与公众接受生活方式助推相关的社会人口特征和生活方式行为。
本研究使用了来自新加坡全国性糖尿病知识、态度和实践研究（KAP）的数据。考察了三种类型的助推措施，按侵入性递增排序：（1）政府宣传信息，（2）政府强制信息，（3）默认规则和选择架构。接受程度是根据受访者对描述健康生活方式助推的相关陈述的“同意”程度来评估的。使用对每种助推措施计算的得分，对社会人口统计学和生活方式行为进行多变量线性回归。
受访者对与每种助推措施相关的所有陈述表示同意的百分比分别为：75.9%（政府宣传信息）、73.0%（政府强制信息）和 33.4%（默认规则和选择架构）。马来/其他族裔（相比华人）的受访者更有可能接受政府宣传信息。18-34 岁（相比 65 岁及以上）、女性、马来/印度族裔（相比华人）、身体活动量充足、饮食更健康（基于 DASH 评分）的受访者更有可能接受与政府强制信息相关的助推措施。马来/印度族裔（相比华人）、饮食更健康的受访者更有可能接受默认规则和选择架构。
个人更喜欢促进健康生活方式的非强制性方法。族裔和生活方式行为与接受助推措施有关，在制定和实施行为导向的健康政策时应予以考虑。
