[Prevalence of metabolic syndrome among 7-17 year-old overweight and obese children and adolescents].
OBJECTIVE
o describe the prevalence of metabolic syndrome (MS) in 7-17 year-old children and adolescents.


METHODS
A stratified multistage cluster random sampling method was adopted, and 2752 children and adolescents were analyzed. MS was diagnosed according to the definition of Cook.


RESULTS
The prevalence of MS among normal weight, overweight, and obese groups was 0.7%, 8.0% and 23.9% respectively. Excluding other influencing factors, the prevalence of MS among the overweight and obese groups was multiplied when compared to the normal weight group. In overweight and obese groups, the present of abdominal obesity (41.6% and 77.9%), hyperglyceridemia (36.4% and 50.7%), and hypertension (19.6% and 39.0%) were more common. The individuals suffered from at least one metabolic abnormality were 40.3%, 65.6% and 90.6% in these three groups. About 62.9% of obese individuals suffered from at least two metabolic abnormalities and 23.9% suffered from at least three metabolic abnormalities. The individuals suffered from at least four metabolic abnormalities were all overweight or obesity.


CONCLUSIONS
There are obvious metabolic disorders in overweight and obese children and adolescents.
