The most accurate way to determine GFR involves the measurement of the rate at which an external substance such as inulin is removed from the bloodstream, termed inulin clearance. The different stages are dependent on other factors in conjunction with GFR, as noted in the table. ![]() Below is a table of GFR ranges for the different stages of CKD. Note that the sooner that kidney disease is diagnosed and treated, the higher the probability that the need for dialysis can be prevented. 1 If, however, there has been a significant decline of GFR since a previous test, this could be an early indicator of kidney disease. ![]() Population Mean Estimated GFR AgeĪ GFR above 60 mL/min/1.73m 2 is usually adequate for most patients and alone is not necessarily indicative of a patient having chronic kidney disease (CKD). Refer to the table below for population mean estimated GFR for a number of age ranges. After age 40, GFR decreases progressively with age. The normal range of GFR adjusted for body surface area is 100 to 130 mL/min/1.73m 2 in men and 90 to 120mL/min/1.73m 2 in women below the age of 40. A significant decrease in GFR indicates that the kidney is not properly functioning, resulting in lower volumes of fluids being filtered over a given time. Generally, a higher value of GFR indicates better kidney function. Glomerular filtration rate describes the rate of flow of filtered fluids through the kidney and is used as a measure of kidney function. What is Glomerular filtration rate (GFR)? This calculator is for people aged 18 years or younger. This calculator is for people aged 18 years or older. For comparison purposes, the results for three prevalent formulas used for estimating GFR are provided. The GFR (glomerular filtration rate) Calculator estimates GFR values based on factors including serum creatinine value, age, race, and gender.

The results confirm structural racism as a latent construct and demonstrate that structural racism can be measured in U.S. County structural racism was associated with reduced BMI for white men and no change for white women. In a further interaction analysis, county structural racism was associated with larger increases in BMI among black men than black women. Structural racism and black race exhibited a qualitative interaction with BMI, such that racism was associated with lower BMI in whites and higher BMI in blacks. County structural racism was associated with lower BMI. A 7-indicator county structural racism model demonstrated acceptable fit. Using Behavioral Risk Factor Surveillance Survey data (2011-2012) and a mixed-effects model, individual BMI was regressed on county structural racism, controlling for county characteristics (mean age, percentage black, percentage female, percentage rural, median income, and region). and evaluates its association with BMI.Ĭounty structural racism was estimated with a confirmatory factor model including indicators reflecting education, housing, employment, criminal justice, and health care. This paper develops a multi-indicator scale measuring county structural racism in the U.S. Structural racism has been measured most often with single-indicator proxies (e.g., housing discrimination), which may leave important aspects of structural racism unaccounted for. Structural racism has attracted increasing interest as an explanation for racial disparities in health, including differences in adiposity.
