Symptoms of depression and anxiety were assessed with specific questionnaires (Patient Health Questionnaire\u20109, Center for Epidemiologic Studies Depression Scale, and Generalized Anxiety Disorder\u20107, respectively). Laboratory data (including leptin and sObR) were collected, and free leptin index (FLI), as an estimate of leptin resistance, was calculated. One hundred forty patients had laboratory data available on both occasions, and were evaluated longitudinally. Simple and multiple correlations between depression\/anxiety and parameters of interest were performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In both studies, serum leptin levels were higher, whereas resting energy expenditure\/leptin ratios were lower in T2D patients with depressive and moderate\u2013severe anxiety symptoms. In the second study, patients with depressive symptoms had higher FLI and lower sObR levels, while those with moderate\u2013severe anxiety only had higher FLI. Depression scores correlated with serum leptin (<jats:italic>r<\/jats:italic> =\u20090.29, [95%CI: 0.14\u20130.42]; <jats:italic>r<\/jats:italic> =\u20090.32, [95%CI: 0.18\u20130.45]) and FLI (<jats:italic>r<\/jats:italic> =\u20090.30, [95%CI: 0.15\u20130.43]; <jats:italic>r<\/jats:italic> =\u20090.32, [95%CI: 0.17\u20130.45]; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.0001 for all).
