Adjusted relative risk of metabolic syndrome by weight change groups in both genders. From the total study population (1431 men and 2036 women), only 1037 men and 1180 women who were free of metabolic syndrome at baseline included in this logistic regression model. The model was adjusted for age, baseline weight, smoking, physical activity, education level and medication use. The gender-stratified percentage of weight change (PWC) was shown in the X axis, grouped as follow: weight loss group [<-1.3% men (n = 191), <-2.5% women (n = 193)]; weight stable group [-1.3 to 1.3% men (n = 185), -2.5 to 1.2% women (n = 204)]; mild weight gain group [1.4 to 3.9% men (n = 209), 1.3 to 3.9% women (n = 228)]; moderate weight gain group [4 to 6.9% men (n = 204), 4 to 7.6% women (n = 233)]; large weight gain group [= 7% men (n = 248), = 7.7% women (n = 322)]. The stable group was considered as reference. Relative risk (95% CI) for ATPIII defined metabolic syndrome according to PWC groups was shown in the Y axis.
