Abdominal obesity and reduction of glomerular filtration

Effectiveness of a dietary re-education and physical activity program on obesity

OBJECTIVE

To evaluate the effects on obesity of a weight loss method that associates dietary re-education and physical activity.

METHOD

A retrospective, cross-sectional, and quantitative study using secondary data from individual follow-up forms of a weight loss clinic located in a municipality in northwestern Paraná, Brazil. Data collection took place in August 2018 through a checklist of anthropometric parameters, being stored in Excel spreadsheets and analyzed by descriptive statistics using the SPSS program.

RESULTS

The mean weight loss was 15.22 kg, and the weight loss method was associated with beneficial results in relation to the following variables: weight, body mass index, body and visceral fat, muscle mass, basal metabolism rate, waist circumference, and hip circumference.

CONCLUSION

The association of dietary re-education with regular physical exercise has a positive impact on obesity.

The fat mass, estimated glomerular filtration rate, and chronic inflammation in type 2 diabetic patients

BACKGROUND

The aim of the study was to analyze the degree of obesity and its associations with age, gender, inflammation, an estimated glomerular filtration rate (eGFR), and liver function in type 2 diabetes mellitus (T2DM) patients.

METHODS

A total of 874 consecutive adult Caucasian T2DM patients from outpatient diabetic clinic were included in the study. The relative fat mass (RFM) and body mass index (BMI) were used as obesity markers. Serum creatinine and cystatin C were used for the GFR estimation. Serum high-sensitive C-reactive protein (hsCRP) was used as the indicator of inflammation.

RESULTS

The median, interquartile range (IQR) of RFM in females was higher than that in males (44.8 (42.3-47.2) % vs 31.3 (28.8-34.1) %, respectively; P < .0001). The median (IQR) of BMI in females was no higher than that in males (30 (27-34) kg/m2 vs 30 (27-34), respectively; P = .5152). The obesity prevalence was 99% in males and 98% in females according to RFM. BMI recognized obesity in 51% males and 53% females. RFM was positively associated with hsCRP in both males (rs  = .296, P < .0001) and females (rs  = .445, P < .0001). ALT was positively correlated with eGFRcys in both males (rs  = .379, P < .0001) and females (rs  = .308, P < .0001).

CONCLUSION

The RFM equation leads to higher obesity prevalence compared to BMI. Women have higher RFM compared to men. The kidney function was positively correlated with ALT serum concentrations.
