Lilja (2012) [9]640Leptin in men and adiponectin in both sexes were independent predictors of T2DM. The association was modified by the degree of insulin sensitivity. The leptin/adiponectin ratio may add predictive information beyond the separate hormones.
McNeely (1999) [10]410Among Japanese Americans, increased baseline leptin levels are associated with increased risk of developing diabetes in men but not in women.
Sans S; Padró T (2013) [29]1011In a population with relatively high diabetes incidence, BMI and glucose were strong risk factors, while adiponectin protected against diabetes, especially in men with high glycemic level.
Schmidt (2006) [13]10275High leptin levels, probably reflecting leptin resistance, predict an increased risk of diabetes. Adjusting for factors purportedly related to leptin resistance unveils a protective association, independent of adiponectin and consistent with some of leptin’s described protective effects against diabetes.
Sun (2010) [16]32826These data suggest a strong inverse association between plasma sOB-R levels and risk of type 2 diabetes, independent of BMI, leptin, and adiponectin levels.
Thorand (2010) [17]7936Two adipokines leptin and adiponectin interact in modulating type 2 diabetes risk, but adiponectin is more strongly associated with type 2 diabetes risk than leptin.
Welsh (2009) [18]5672Leptin, similar to other markers of adiposity in general, is more strongly related to risk of diabetes than CVD in the elderly.
Söderberg (2007) [19]2330High leptin levels are associated with the future development of diabetes, and the association is independent of other factors in men, but not in women.
Kouvari (2021) [20]2020Report an inverse association between Mediterranean diet and NAFLD. Mediterranean diet protected against diabetes and CVD prospectively among subjects with NAFLD.
Peller (2020) [21]273In type 2 DM, patients with AF have higher resistin and adiponectin concentrations than patients with no AF. None of the studied adipokines proved a predictor of future AF development.
