Background: Depression is prevalent in patients with all stages of CKD and is associated with adverse outcome. Abnormally elevated GFR, or hyperfiltration, may play a crucial role in the initiation and progression of CKD. However, the association between depression and hyperfiltration is not known. The aim of this study is to investigate the relationship between depression and hyperfiltration. Methods: This was an observational cross-sectional study. A total of 3,716 volunteers (1,303 males and 2,413 females) aged 40–75 years without CKD from a community in China were included for the study. Depressive symptoms and the presence of a minor or major depressive episode were assessed with the 9-item Patient Health Questionnaire (PHQ-9) and Diagnostic and Statistical Manual of Mental Disorders (4th edition)-based structured interview, respectively. Results: The mean age of the participants in the present study was 53.8 ± 9.0 years. 115 participants had clinically relevant depression, and 122 participants had a minor or major depressive episode. In a multivariable logistic regression analysis adjusted for potential confounders, the association between clinically relevant depression and renal hyperfiltration remained significant in men but not in women. As compared with men without depression (PHQ <5) or depressive episodes, those with clinically relevant depression (PHQ ≥10) had a significantly higher risk of renal hyperfiltration. The fully adjusted OR (95% CI) was 4.81 (1.62–14.30, p = 0.005), those with a major depressive episode had a higher risk of renal hyperfiltration (OR 7.45; 95% CI 2.04–27.21, p = 0.002). Conclusion: Depressive symptoms and major depressive episodes are associated with renal hyperfiltration in middle-aged and elderly Chinese men without CKD. Future studies are needed to verify and clarify the role of depression in the development of abnormally high eGFR and CKD. [ABSTRACT FROM AUTHOR]

Background: Little is known about the prevalence and cardiovascular risk factors for prehypertension and hypertension in the She ethnic minority population of Fujian province in China. Methods and Results: Between April 2009 and September 2009, 5,523 participants of She nationality aged between 20 and 80 years participated in this survey and 5,357 were eventually enrolled in analyses. The survey was carried out to assess blood pressure and cardiovascular risk factors. The prevalence of prehypertension and hypertension was 35.87 and 38.42%, respectively, in all participants. Only 26.63% of the subjects with hypertension were aware of their diagnosis. Multivariate logistic regression showed that age, gender, overweight/obesity, dyslipidemia and alcohol use were risk factors for prehypertension, and age, overweight/obesity, dyslipidemia, alcohol use, family history of hypertension and hyperuricemia were risk factors for hypertension. The clustering of 2 and ≥3 risk factors was in higher proportion for subjects with hypertension and prehypertension when compared with those with prehypertension and normotension, respectively. After adjusting for other confounding factors, multivariable logistic regression showed that the greater the number of clustering cardiovascular risk factors, the greater the odds ratios for prehypertension and hypertension are. Conclusion: Hypertension and prehypertension were common in the She population of Fujian province. Cardiovascular risk factors cluster during prehypertension and awareness of hypertension was minimal. Early lifestyle modifications could be advocated to prevent the transition from prehypertension to hypertension and cardiovascular disease. Copyright © 2012 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]
