*Age-standardized prevalence rates.
†Age-standardized and sex-standardized prevalence rates. Standardization was conducted with the 2010 Chinese National Census Population by the direct method.
^‡P < 0.001, significantly higher than for the other sex.
^¶P < 0.001, the standardized proportions were significantly different among the MMRR, JCDCG and IDF criteria.
^§P < 0.001 comparing the JCDCG with the MMRR criteria. ^ÿP < 0.001 comparing the IDF with the MMRR criteria.
MetS, metabolic syndrome; MMRR, multivariate medical reference range; JCDCG, Chinese Joint Committee for Developing Chinese Guidelines; IDF, International Diabetes Federation; WC, waist circumference; TG, triglycerides; HDL-C, high-density lipoprotein cholesterol; SBP/DBP, systolic/diastolic blood pressure; FPG, fasting plasma glucose.
