RESUMO
The objective of the study was to evaluate the effects of a 10-month lifestyle intervention on the components of the metabolic syndrome (MetSyn) in Koreans with MetSyn as well as on blood concentrations of adiponectin and vaspin. One hundred thirty-eight patients with MetSyn, recruited from a community health care center, were consecutively enrolled in the study; 12 patients dropped of the intervention, leaving 126 subjects (76 men and 50 women; age, 65.3 ± 9.0 years). All participants followed a 10-month lifestyle modification interventional program, including dietary counseling, advice on increasing physical activity, and recommendations to stop or limit smoking and alcohol drinking. Anthropometric and biochemical parameters related to the components of the MetSyn, including blood concentrations of adiponectin and vaspin, were assessed pre- and postintervention. At baseline, adiponectin concentrations were moderately negatively correlated to insulin concentrations and insulin resistance evaluated by the homeostasis model assessment. In response to lifestyle modification, statistically significant changes were found in systolic and diastolic blood pressure, total cholesterol, triglyceride, and insulin concentrations, as well as in homeostasis model assessment of insulin resistance. Adiponectin concentrations postintervention, compared with the preintervention levels, increased (7.2 ± 4.0 vs 6.8 ± 3.9 µg/mL, respectively; P < .05), whereas vaspin concentrations remained unchanged (0.25 ± 0.19 vs 0.26 ± 0.20 ng/mL, respectively; P = .64). A 10-month lifestyle modification program in Korean patients with MetSyn led to favorable changes in metabolic parameters and adiponectin but not vaspin concentrations.
