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.
