Abstract Background Appropriate diet is an important determinant of kidney health. However, the association between vegetarian diets and renal function is unclear. Object We aimed to study the association between vegetarian diets and renal function in healthy adults. Design A total of 269 vegetarians (aged 34.5±8.7 years) and 269 sex- and age-matched nonvegetarian omnivores were enrolled in this cross-sectional study. Basic characteristics as well as daily dietary intakes were assessed by face-to-face interviews. Blood samples were collected, and renal function was assessed by measuring blood urea nitrogen (BUN), creatinine (Cr), uric acid (UA) and estimated glomerular filtration rate (eGFR). Blood pressure, fasting blood glucose and blood lipid profiles were also assessed. Results The average age of the vegetarians was 35.4±8.6 years, 82.2% of whom were female. We evaluated the association between vegetarian diets and renal function by using multivariate analysis. Compared with omnivores, vegetarians had lower BUN (β= -0.63, 95% CI: -0.88 to -0.38), SCr (β= -2.07, 95% CI: -4.21 to -0.061), UA (β= -15.17, 95% CI: -27.81 to -2.53) and higher eGFR levels (β= 4.09, 95% CI: 0.23 to 7.96) after adjusting for sex, age, BMI, physical activity, alcohol consumption, smoking status, LDL, HDL, systolic pressure and fasting blood glucose. Further analysis of food composition and renal function showed that dietary fiber intake was significantly negatively associated with BUN [β= -0.02, 95% CI:(-0.03, 0.00)], SCr [β= -0.14, 95% CI:(-0.25, 0.04)], and UA [β= -0.72, 95% CI:(-1.36, 0.07)] and positively associated with eGFR [β= 0.20, 95% CI:(0.00, 0.40)]. Conclusions Healthy adult vegetarians have better renal function than omnivores, and the higher dietary fiber intake associated with vegetarian diets may contribute to the protective effect on renal function.

Methods: A total of 269 vegetarians and 269 sex- and age-matched nonvegetarian omnivores were enrolled in this cross-sectional study. Basic characteristics and daily dietary intakes were assessed by face-to-face interviews. Blood samples were collected, and renal function was assessed by measuring blood urea nitrogen (BUN), serum creatinine (SCr), uric acid (UA) and the estimated glomerular filtration rate (eGFR). Blood pressure, fasting blood glucose and blood lipid profiles were also assessed.Results: The average age of the vegetarians was 35.4±8.6 years, 82.2% of whom were female. We evaluated the association between vegetarian diets and renal function using multivariate analysis. Compared with omnivores, vegetarians had lower BUN [β= -0.63, 95% confidence interval (CI): (-0.88 , -0.38)], SCr [β= -2.04, 95% CI:(-4.10, 0.02)], and UA levels [β= -15.15, 95% CI: (-27.81, -2.50)] and higher eGFRs [β= 4.04, 95% CI: (0.30, 7.78)] after adjusting for sex, age, body mass index (BMI), physical activity, alcohol consumption, smoking status, low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), systolic pressure and fasting blood glucose. Further analysis of food composition and renal function showed that dietary fiber intake was significantly negatively associated with BUN [β= -0.02, 95% CI: (-0.03, 0.00)], SCr [β= -0.14, 95% CI: (-0.25, 0.04)], and UA levels [β= -0.72, 95% CI: (-1.36, 0.07)] and positively associated with the eGFR [β= 0.20, 95% CI: (0.00, 0.40)].

Elevated serum Transforming growth factor-beta1 (TGF-beta1) levels have been linked to tissue fibrosis including chronic kidney disease. Objectives: (1) Investigate serum TGF-beta1 levels in healthy adult people and (2) Examined the relation between serum TGF-beta1 level and gender, age, body mass index (BMI). Method: A cross-sectional study. TGF-beta1 were quantified by ELISA. Results: Levels of serum TGF-beta1 in healthy people were 13,45 ± 7,17 ng/mL mL (0,59 - 33,10 ng/mL). There are no difference of serum TGF-beta1 levels between men and women, between the age groups (<40 years, 40 to < 60 years and ≥ 60 years), between BMI groups < 23 and BMI group ≥ 23. Key words: TGF-beta1, healthy people

Abstract Background and Aims Both constipation and chronic kidney disease (CKD) are common among seniors. However, the association between constipation and CKD remain unclear. This study investigates the correlation between the two to provide a new basis for clinical treatment. Method Data from Shanghai community elderly physical examination database (2010-2018) were used to conduct a cross-sectional study and a retrospective cohort to evaluate the relationship between constipation and the prevalence of CKD and rapid renal function decline in the elderly community. Results The cross-sectional study covered 16,177 participants, with an average age of 71.3. Comparing to no constipation group, seniors with constipation have a higher proportion of suffering from CKD stage 3. Constipation is an independent risk factor contributing to the high prevalence of CKD stage 3 (OR:1.238,95% CI,1.045-1.466). This finding was further tested through a retrospective cohort study that included 4,203 participants with a medium following time of 6.1 years. As a result, 9.5% (n=401) reported to have rapid progression of renal function. After adjustment of confounding factors, the logistic regression analysis indicates that, constipation is an independent predictive variable of rapid renal function decline among aged population. Conclusion Constipation is an independent risk factor for the prevalence of CKD and an independent predictor of rapid renal function decline among seniors in the community. Prevention and treatment for constipation should be taken at an early stage, which may reduce the incidence of CKD and delay the progression of CKD.
