Methods The study is a cross-sectional survey of parents who took their 0 to 6-year-old children for seeking primary care services at the Children Preventive Health Care Clinic of a tertiary hospital in Shandong Province, China.

The result of logistic regression analysis show that parents with junior college (OR = 0.398, 95%CI: 0.185 ~ 0.857), possessing a high family economic status(OR = 0.225, 95%CI: 0.088 ~ 0.578), being trained on children’s unintentional injuries(OR = 0.435,95%CI: 0.272 ~ 0.695), and having high scores on CRS riding mode cognition(OR = 0.476, 95%CI: 0.368 ~ 0.616), CRS type cognition(OR = 0.519, 95%CI: 0.392 ~ 0.689), CRS use motivation(OR = 0.392, 95%CI: 0.295 ~ 0.520) and installation skills(OR = 0.559, 95%CI:0.411 ~ 0.761) were the main factors promoting the usage of CRS.
