Abstract

Objective:

To describe the prevalence of cardiometabolic risk factors in Chinese children and adolescents.

Design and Method:

Stratified cluster sampling method was used, 12 590 (boys: 6370, 50.6%) children aged 6–18 years were recruited from seven urban cities in 2013–2014. Height, weight, waist circumference (WC) and blood pressure were measured. The levels of fasting plasma glucose, triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were examined. General obesity was diagnosed based on body mass index and abdominal obesity based on WC. Hypertension was diagnosed according to blood pressure reference standards for Chinese children. Hyperglycemia was defined as a fast glucose level ≥5.6mmol/L. Dyslipidemia was diagnosed by the recommends of dyslipidemia in Chinese children. Metabolic syndrome (MS) was diagnosed by International Diabetes Federation (IDF) and Chinese standard (CHN), respectively.

Results:

The standardized overall prevalence of general obesity and abdominal obesity were 11.5% and 21.3%, the prevalence of hypertension was 17.9%, hyperglycemia was 23.7%, elevated TG was 4.7%, elevated TC was 4.1%, elevated LDL-C was 3.1% and low HDL-C was 9.1%. The standardized prevalence of MS appeared 3.2% according to IDF and 5.4% according to CHN. The prevalence of general obesity was negatively correlated with age for both genders. The prevalence rates of general obesity, abdominal obesity, hypertension and hyperglycemia were all higher in boys than in girls. Both the results from IDF and CHN showed that the prevalence of MS as boys >girls, obesity >overweight >normal weight, Northern >Southern.

Conclusions:

The prevalence rates of multiple cardiometabolic risk factors were high in urban Chinese children. Attention should be paid to identifying and carrying out effective interventions on children, especially in boys.
