ABSTRACT
Objective@#To describe characteristics of cardiometabolic risk factors of children and adolescents aged 6-17 years in 7 cities in China from 2013 to 2015.@*Methods@#Data was from the China Child and Adolescent Cardiovascular Health (CCACH) study. 12 590 children and adolescents were selected from 24 schools (3 kindergartens, 7 primary schools, 7 junior high schools and 7 senior high schools) in seven cities (Changchun, Yinchuan, Beijing, Jinan, Shanghai, Chongqing and Tianjin) during 2013-2015 by using a stratified cluster random sampling method. The demographic characteristics, e.g. birth date, feed status and history of disease, were collected by questionnaires. Anthropometric measurements, i.e. weight, height, waistline, blood pressure, total cholesterol, fasting plasma glucose, triglyceride and high-density lipoprotein, were also collected. The detection rate of metabolic syndrome was calculated respectively according to "international diabetes federation standard " and "definition and prevention of metabolic syndrome in Chinese children and adolescents " .@*Results@#The prevalence of cardiometabolic risk factors such as obesity, hypertension, hyperglycemia and dyslipidemia was 12.0%(1 497/12 491), 18.2%(2 193/12 035), 24.4%(3 028/12 422) and 15.8%(1 977/12 490), respectively. The prevalence of these four cardiometabolic risk factors in males was significantly higher than that in females (all P values<0.05). The prevalence of metabolic syndrome was 3.3%(272/8 328) with international diabetes federation 2007 definition and 5.4% (453/8 325) with Chinese definition among children above 10 years old. The prevalence of hypertension, hyperglycemia, hypertriglyceridemia, high total cholesterol, low high-density lipoproteincholesterol and dyslipidemia increased with the change of obesity type from non-obesity to complex obesity (all P values<0.001).@*Conclusion@#The prevalence of cardiometabolic risk factors was still high in children and adolescents, which has become an important factor threatening the healthy growth of children and adolescents.
ABSTRACT
Childhood obesity has become a critical issue in public health area. We searched Wanfang Data and PubMed databases for published studies on health hazards of childhood obesity in China during 2000-2015. From the evidence of the Chinese population studies, we know childhood obesity brings not only cardiovascular, endocrine and respiratory system health hazards, but also other health hazards to liver, moving skeleton, psychological behavior and cognition intelligence, et al. Only to understand the health hazards of childhood obesity, and put the key preventable period of chronic diseases forward to childhood, can pandemic of chronic diseases be controlled from the sources.

Objective To evaluate the prevalence of metabolic syndrome (MS) in Chinese children and adolescents to provide scientific basis for early prevention of MS in the related populations.Methods Studies on CNKI,Wanfangdata,VIP and PubMed databases on related prevalence of metabolic syndrome in Chinese children and adolescents between 2004-2014 were searched.Quality of literatures was evaluated according to the cross-sectional study standard in Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement.Stata 12.0 software was used to estimate the prevalence of MS,as well as on gender,weight and other factors to make subgroup analysis.According to funnel plot and Egger assess publication bias,sensitivity analysis performed by excluding the impact of any article was generated by the combined effect of the value of literature.Results This study included 19 papers from the literature (5 in English,14 in Chinese).According to International Diabetes Federation (IDF),National Cholesterol Education Program Ⅲ (NCEP Ⅲ) and The definition and prevention recommends of metabolic syndrome in Chinese children and adolescents (CHN2012),the prevalence rates of MS in Chinese children were seen as 1.8％,2.6％ and 2.0％.According to IDF,the prevalence rates of MS appeared 2.9％ in boys and 1.8％ in girls,0.2％ in children with normal weight,4.7％ in overweight and 17.3％ in obesity.Both the results from NCEP Ⅲ and CHN2012 showed that the prevalence rates of MS as boys＞girls,obesity＞overweight＞normal weight.Conclusion Prevalence of MS in Chinese children and adolescents showed a general trend.Data under different standards showed different prevalence rates.Obesity appeared an important risk factor of MS,suggesting that in order to control obesity in children,attention should be paid to identifying and carrying out effective interventions on children under overweight or obesity.
