Abstract In China, road traffic injury has been the 2nd leading cause of death for minors aging from 1 to 14 years old, has become an urgent public health problem in China. This paper introduces the current situation of children s road traffic accident injuries. Based on Haddon s model, the influencing factors of children s road traffic safety are summarized into two aspects:individual and environmental levels. Also it puts forward targeted strategies for children road safety, including improving the relevant laws and regulations system, releasing commercial insurance into children CRS evaluation criteria, improving the safety awareness level of parents, strengthening the campus traffic safety education and optimizing the road safety protection facilities, all of which could contribute to protect child safety, thus providing reference for China to improve the road traffic safety education for children.

Objective:To analyze the current situation of pregnant women′s health promotion behavior in early pregnancy, and to explore the multiple mediating effects of self-efficacy and sense of coherence in family function and health promotion behavior.Methods:The convenience sampling method selected 208 early pregnant women who visited the obstetric clinic of the Affiliated Hospital of Qingdao University from August to December 2020 as the research object was used. The electronic questionnaires including self-made general information questionnaire, Family APGAR Questionnaire, General Self-Efficacy Scale (GSES), Sense of Coherence Scale (SOC-13), and the Health-Promoting Lifestyle ProfileⅡ (HPLP-Ⅱ) were provided to women.Results:The total score of health promotion behaviors for early pregnancy was (139.58 ± 17.27) points with a good level. The influencing factors such as exercise habits and medical payment methods had statistical significance in the effects of health-promoting behaviors in the first trimester of pregnancy ( t=4.68, -3.55, both P<0.05). Structural equation model revealed that the total effect value of family function on health-promoting behaviors was 2.654, the direct effect value was 1.729 and the indirect effect value was 0.925. Meanwhile, the mediating effects of self-efficacy, the sense of coherence and self-efficacy upon the sense of coherence accounted for 15.9%, 15.2% and 3.8% of the indirect effect respectively. Conclusions:Family function of pregnant women in early pregnancy can not only affect health promotion behavior through self-efficacy and sense of coherence, but also indirectly affect sense of coherence through self-efficacy, so as to affect health promotion behavior. Maternal related health workers can construct targeted intervention measures from the perspective of self-efficacy and sense of coherence to maintain and improve the health promotion behavior of pregnant women in the early stage of pregnancy.
