[Study on the prevalence of metabolic syndrome among 35-74 year-olds in Jiangsu province].
OBJECTIVE
To describe the prevalence of metabolic syndrome (MS) in Jiangsu province, using IDF 2005 and ATP III 2005 definition.


METHODS
Multistage cluster sampling method was used and the participants were interviewed by trained health workers under a structured questionnaire. The number of research subjects was 5888. Fasting plasma glucose (FPG), blood lipids, body mass index, blood pressure (BP) of all sample population (5888 subjects) were measured.


RESULTS
The prevalence of MS was 17.48% by IDF 2005 definition and 21.95% by ATP lII 2005 definition. Women had higher prevalence than men (P < 0.01). The prevalence of MS increased with age. Abrupt increase of the prevalence started at age of 50 in women. The prevalence varied by education, marital status, occupation and income. People from the urban and the south had a higher prevalence than from the rural and from the northern part of the country. The most common combination of MS individual components were 1) central obesity, dislipidemia and high BP; 2) central obesity, dislipidemia, high BP and high FPG.


CONCLUSIONS
The prevalence of MS was high in Jiangsu province. Clustering of MS components was common. It is necessary to discuss the cut-off points of central obesity for the waist circumference diagnostic criteria of MS in Chinese population. The importance of prevention of MS should be strengthened both by health professionals and the government.
