Does a 3-month intensive lifestyle management-focused weight-loss program improve adipokines, body composition, and metabolic biomarkers in overweight and obese women?
A 3-month intensive lifestyle weight-loss program in overweight and obese women significantly improves metabolic and cardiovascular risk biomarkers, including favorable changes in adipokines.
Obesity among aging women is associated with increased risk for metabolic and cardiovascular diseases. Weight-loss has been shown to reduce disease risk; however, it remains unclear how changes in adipokines following weight-loss are associated with markers of metabolic and cardiovascular health in women. The aim of this study was to determine the effects of a 3-month intensive lifestyle management-focused weight-loss program on the interactions between adipokines, total and regional body composition, and biomarkers of cardiovascular and metabolic health. Women who were overweight or obese (n = 43, age = 49.2 ± 1.5 years, body mass index (BMI) = 34.5 ± 0.9 kg/m2; waist circumference (WC) = 99.8 ± 2.2 cm) completed a 3-month weight-loss program consisting of a reduced energy intake to 1200–1500 kcals/day combined with a progressive walking program targeting 300 min/wk. At 3-months, average body mass was reduced 8.3 % (ΔBMI −8.0 %; ΔWC −6.6 %). Weight-loss lowered fasting glucose (−12.1 %), insulin (−23.2 %), total cholesterol (−11.0 %), and LDL-C (−12.2 %) concentrations, and HOMA-IR (−32.4 %). Leptin was decreased 32.6 %, high molecular weight (HMW) adiponectin increased 25.0 %, and adiponectin:leptin ratio increased 1.27-fold. The change in fat mass was positively correlated with Δleptin (r = 0.527) and inversely correlated with Δadiponectin:leptin ratio (r = −0.547). The ΔHMW adiponectin inversely correlated with Δinsulin (r = −0.360) and ΔHOMA-IR (r = −0.304), and ΔLDL-C (r = −0.305), whereas Δleptin correlated with Δtriglyceride (r = 0.366) and Δtotal cholesterol (r = 0.402). Weight-loss in women who were overweight and obese was associated with a reduction in leptin and increase in HMW adiponectin and adiponectin:leptin ratio. Correlations revealed that changes in these adipokines were uniquely associated with improvements in select markers of metabolic and cardiovascular disease risk.
Wooten et al. (Wed,) conducted a observational in Overweight and obesity (n=43). Intensive lifestyle management-focused weight-loss program was evaluated on Changes in adipokines, total and regional body composition, and biomarkers of cardiovascular and metabolic health. A 3-month weight-loss program in overweight and obese women reduced body mass by 8.3%, decreased leptin by 32.6%, and increased high molecular weight adiponectin by 25.0%.
