Abstract: Background　Dyslipidemia is a major cause of atherosclerosis.The incidence of dyslipidemia in Chinese children is rising recently.As a basis for early detection，correct diagnosis and treatment of childhood dyslipidemia，and a key to developing children's appropriate dietary habit and healthy lifestyle，pediatric healthcare providers and parents' appropriate awareness levels of dyslipidemia play an important role in early detection，prevention and control of dyslipidemia in childhood and adolescence.Objective　To explore Beijing pediatric healthcare providers' awareness of dyslipidemia incidence in childhood and adolescence and their willingness to get their child（ren） screened for lipid level，providing a reference for early detection，prevention and control of dyslipidemia in children and adolescents.Methods　A questionnaire survey was conducted among pediatric healthcare providers with a child or children younger than 20 years who attended Beijing Projects for Comprehensive Early Childhood Development and Scientific Rearing from April to September 2019，mainly focusing on their awareness levels of dyslipidemia incidence in childhood and adolescence and willingness to get their child（ren） screened for lipid level，specifically including their child（ren）'s gender and age，awareness of dyslipidemia incidence in children and adolescents，residential area（rural or urban），workplace，occupation，family history of early-onset cardiovascular and cerebrovascular diseases in first-and second-degree relatives，awareness level of lipid in their child（ren） and willingness to get him（them） screened for lipid level，as well as education level of their own and their spouse.Those who chose “children have a dyslipidemia incidence greater than 5%”，and those who chose “children have a dyslipidemia incidence less than 5%” or “children have unstable lipid level” were assigned to correct and incorrect knowledge groups，respectively.Multivariate Logistic regression analysis was used to explore the influencing factors of pediatric healthcare providers' knowledge of dyslipidemia in children and adolescents.Results　There were 247 cases（46.2%） in correct knowledge group，and 288（53.8%） in incorrect knowledge group〔including 109（20.4%） and 179（33.5%） who chose “children have a dyslipidemia incidence less than 5%” or “children have unstable lipid level”〕．Two groups had significant differences in workplace and education level（P<0.05）.Multivariate Logistic regression analysis showed that education level was associated with awareness of dyslipidemia in children and adolescents （P=0.042）.Of the respondents，the rates of knowing their child（ren）'s blood lipid level，knowing the importance of screening for lipid level and willing to get their child（ren） screened for lipid level were 8.2%（n=45），90.4%，and 95.4%（n=523），respectively.Conclusion　More than half of these pediatric healthcare providers had insufficient knowledge of the incidence of dyslipidemia in children and adolescents.Education level may be associated with their awareness level.The overwhelming majority of them did not know their children's blood lipid levels，but thought that dyslipidemia in children was noteworthy and supported the screening for lipid level in children and adolescents.
