ABSTRACT
Objective: To explore the relationship between the changes of plasma levels of resistin with the contemporary body weigh changes in the same population. Methods: The community based epidemiological surveys were carried out in the same population in Shijingshan district of Beijing at the year of 2005 and year of 2010. A total of 943 subjects with the entire information of cardiovascular related risk factors were enrolled including 316 male with the mean age of (58.2 ± 8.5) years and 627 female with the mean age of (59.3 ± 7.5) years. Plasma levels of resistin in both year of 2005 and year of 2010 in all subjects were recorded, and the subjects were divided into 4 groups based on the quartile levels of resistin. Group①, the subjects with plasma level of resistin ≤ (-0.66) mmol/L,n=239, Group②, resistin level (from -0.67 to 0.25) mmol/L,n=233, Group③, resistin level (0.26-1.24) mmol/L, n=235 and Group④, resistin level ≥1.25 mmol/L,n=236. Pearson correlation study with uni- and multi- regression analysis were conducted to investigate the relationship between the changes of plasma levels of resistin with the contemporary body weight changes in the same population.Results: The uni-variate analysis showed that in female subjects, plasma levels of resistin were obviously related to the percentage (%) of body weight changes (correlation coefifcient: 0.1173), body weight index (kg/m2) changes (0.1521), the% of body weight index changes (0.1412), the waist circumference (cm) changes (0.1228) and the % of waist circumference changes (0.1057) respectively, allP0.05. Multi-regression analysis indicated that with adjusted baseline variables, in female subjects, the plasma levels of resistin were obviously related to body weight (kg) changes and the % of body weight changes (regression coefifcient: 0.0261 and 0.2916), body weight index (kg/m2) changes and % of body weight index changes (0.2157 and 0.3072), the waist circumference (cm) changes and the% of waist circumference changes (0.0532 and 0.2738) respectively, allP0.05. Conclusion: The changes of plasma levels of resistin are signiifcantly related to contemporary body weight changes in female subjects, but not in male subjects.
