Abstract: Objective To examine the association between parental overweight or obesity and clustering of cardio-metabolic risk factors in children, so as to provide scientific evidence for prevention and control of cardiovascular risk factors. Methods A convenient cluster sampling method was used to conduct a cross-sectional study from a primary school in Huantai county, Zibo city, Shandong.A total of 1 280 children aged 6-11 years with complete data on physical examinations, information from a questionnaire and blood biochemical variables were enrolled in this study.The correlation between parental overweight or obesity and clustering of cardio-metabolic risk factors in children was analyzed. Results The prevalence rates of overweight or obesity among either and both parents were 55.6% and 19.8%, respectively.The prevalence rates of abnormal metabolic indices (abdominal obesity and elevated blood pressure) and the clustering of abnormal metabolic indices were significantly different among parents with different weight status (P<0.05 or <0.001).Compared with children whose parents both had normal weight, those whose either mother or father was overweight or obese had higher risk for developing abdominal obesity(OR＝2.00) and one abnormal metabolic indices(OR＝1.47)(P<0.05 or <0.001).However, children whose parents both had overweight or obesity had much higher risk of developing abdominal obesity(OR＝3.08), elevated blood pressure(OR＝1.74) and abnormal metabolic indices(OR＝1.64-4.60) (P<0.05 or <0.001). Conclusion Parental overweight or obesity is associated with abdominal obesity, elevated blood pressure and clustering of abnormal metabolic indices in children, suggesting high-risk children whose parents had history of overweight and obesity should be prioritized for giving intervention.
