Abstract:
Objective To investigate the prevalence of chronic kidney disease (CKD) and the association of obesity with CKD among hypertension patients registered at community health service centers in suburb of Shanghai.
Methods The participants of the study were 3 600 hypertensive patients randomly recruited from chronic disease patients registered at two community health service centers in a suburban district of Shanghai city. Face-to-face interview with a self-designed questionnaire and the International Physical Activity Questionnaire, physical examination, laboratory tests were conducted among the participants during October – December 2021. Unconditional multivariate logistics regression model was adopted to analyze the association between body mass index BMI and CKD.
Results Of the 2 991 participants finally included in the analysis, 1 037 (34.67%) were identified as having CKD and the number (proportion) of the participants with decreased estimated glomerular filtration (eGFR), proteinuria, and hematuria were 464 (15.51%), 677 (22.63%), and 99 (3.31%), respectively. After adjusting for age, sex, education, smoking, alcohol drinking, physical activity, diabetes, blood lipids and blood pressure control, unconditional multivariate logistic regression analysis revealed that the participants with obesity (BMI ≥ 28.0) were at a significantly increased risk of having CKD (odds ratio OR = 1.498, 95% confidence interval 95%CI: 1.203 – 1.866), decreased estimated glomerular filtration (OR = 1.340, 95%CI: 1.001 – 1.793), and proteinuria (OR = 1.388, 95%CI: 1.088 – 1.771) compared to those with normal or low body weight (≤ 23.9).
Conclusion The prevalence of CKD was high and positively correlated with obesity among hypertension patients registered at community health service centers in suburb of Shanghai.
