Out-of-hospital cardiac arrest (OHCA) is an important public health challenge worldwide [1]. The survival rate of OHCA is less than 1% in China compared with 12% in the USA [2]. Previous studies have shown that immediate bystander-initiated cardiopulmonary resuscitation (CPR) and early defibrillation are essential to improve survival after OHCA [3]. However, the bystander CPR and CPR training rates remain insufficient, even in Western countries. This observational, national, cross-sectional survey aimed to investigate the prevalence of previous CPR training and willingness to be trained in CPR in the Chinese adults and to determine the associated factors.
A cross-sectional study was carried out in China from December 2018 to February 2019. A multistage stratified random sampling design was used in this study. First, a total of 31 Chinese provinces were classified as developed, developing, and less-developed regions according to per capita household income in 2018. Second, we selected 10 urban communities and 10 rural towns randomly from each province. Third, according to the number of residents and the scale of the community or town, from each sampled community or town, 30% of the residents who had lived in that county (or district) for at least 6 months were randomly selected to complete a self-administered questionnaire. Figure 1 shows the flowchart for recruitment and response rates. The questionnaire was shown in Supplement.

Among the 99,186 respondents, more than half were women, and 59.9% were from developed regions. A minority of participants (37.6%) (n = 37,278) had attended a previous CPR training, and 21.5% respondents (n = 21,299) were familiar with automated external defibrillator (AED).
Overall, 73.4% of participants reported that they were willing to attend CPR training, 9.0% were unwilling to attend CPR training, and 17.7% were unsure of their willingness.
Participants who were female (OR = 1.68), had a higher education level (senior high school: OR = 1.47; college degree: OR = 1.77; bachelor’s degree or above: OR = 2.05), and had lower income (middle: OR = 1.62; low: OR = 1.61) were more likely to be willing to learn CPR. In addition, Chinese adults who had prior CPR training (OR = 1.70) and who were familiar with utilizing an AED (OR = 1.15) had high odds of attending CPR training. (Table 1).

The percentage of adults with CPR training was higher than that reported for the general population in Japan (35%) [4], but lower than in most developed countries, such as Sweden (45%) [5] and Crimea (53%) [6]. The differences might be due, at least in part, to differences in sample size and the participants’ characteristics, including their socioeconomic status and the CPR training awareness in their national context.

Our study showed that 73.4% of the respondents were willing to learn CPR, which was higher than in previous studies conducted in other countries [6]. These findings indicate that CPR training is highly acceptable to the public. Previous research has shown that socioeconomic disparities exist with regard to attending CPR training and surviving an OHCA [6]. The findings suggest that willingness to attend CPR training may also correlate with socioeconomic factors, specifically with educational attainment. We identified an independent association between having a higher education level and an increased likelihood of attending CPR training.
No significant association between place of residence and willingness of attend CPR training was found in our study, which was consistent with a previous study [6]. However, a previous study conducted by Axelsson et al. [5] showed that urban residents were more willing to learn CPR. This finding may signal to institutions to provide equal CPR training opportunities and projects for rural and urban residents in China.
The Chinese government should make efforts to optimize and standardize a national model of CPR delivery training and enhance the public awareness and motivation to increase the willingness to attending CPR training.
We would like to thank the study participants and all staff members involved in this study for their efforts in the data collection.
