Ellison MD, McBride MA, Taranto SE, Delmonico FL, Kauffman HM (2002) Living kidney donors in need of kidney transplants: A report from the organ procurement and transplant network. In 2018, African American women were 50 percent more likely to be obese than non-Hispanic white women. Muzaale AD, Massie AB, Wang MC, Montgomery RA, McBride MA, et al. Blacks have a greater need for kidney transplants than other American ethnic groups. "I have much more emphasis on the actual lifestyle, exercising and eating healthy," she says. Thirty-eight males fell above the cut-off of 130 for eGFR at the initial step of the CART while 60 males fell below this cut-off. Is BMI an appropriate measure of health for everyone? The strongest predictor of eGFR for males was WC. All Rights Reserved. Cherikh WS, Young CY, Kramer BF, Taranto SE, Randall HB, et al. View Table 2, Table 3: Unadjusted associations between BMI, WC, eGFR, and explanatory variables. Fat that builds up on the hips and thighs, or the "pear" shape, isn't as potentially harmful. In 2018, non-Hispanic blacks were 1.3 times more likely to be obese as compared to non-Hispanic whites. Sex differences in WC cut-offs were utilized to stratify participants as non-obese or obese. Explanations for these live donation data are few. View Table 1. Within this model, younger men were nearly five times as likely to have eGFR > 130 than older men (OR = 4.855). WebMD does not provide medical advice, diagnosis or treatment. Compared to whites with the same weight and BMI, African-Americans tend to have less visceral fat (fat around their organs) and more muscle mass, Atkinson says. In the CART analysis, the upper value in each node corresponds to the number of subjects with an eGFR greater than 130 while the lower value corresponds to the number of subjects with an eGFR less than or equal to 130.

Pearson correlations and multiple regressions were utilized to assess initial relations between BMI, waist circumference, eGFR, and other explanatory variables. There has been a sustained effort to encourage live kidney donation among Blacks in the past three decades, and organ donation has consistently risen within this community [1-3].

After Tendai suffered a miscarriage, she decided she didn't want to have any more children and set her mind on getting her fallopian tubes tied - a permanent form of contraception. "People who are older probably should have a little more fat on them, [but] they shouldn't have a BMI of 30," Atkinson says. The goal is for your waist circumference to be less than half of your height. Figure 2: Classification and regression tree analysis: Males. Ejerblad E, Fared CM, Lindblad P, Fryzek J, McLaughlin JK, et al. The final node was defined by BMI with a cut-off of 34.

The CART does not suggest that WC is an important predictor as the logistic regression did; however, it does suggest that SBP is predictive of eGFR, but this finding is not strong given its late appearance in the CART. Clive O Callender, Department of Surgery, Howard University School of Medicine, USA. In contrast, many African-Americans may have a high BMI, but without the health risks that usually go along with it. "They're heavy. It may be even more helpful than waist circumference alone, Kahan says. Research has found an association between obesity in Black live kidney before-donation and poorer renal function several years after donation [19]. Covariates included age, systolic blood pressure, self-reported hypertension, and self-reported diabetes.

Among women, WC-categorized obese women were almost six times as likely to have an eGFR > 130 (OR = 5.872). Recursive partitioning was employed to force the data into homogeneous groups according to an entropy criterion [18]. Remaining ones must diversify, says Teddy Edwardes, The young women on a mission to reclaim the word 'pussy', Black people are more likely to be overweight than white people. Analyses were stratified by gender. Previous findings have identified eGFR greater than 130 as a marker for hyper filtration [16,17]. (2019) BMI, Waist Size, GFR: In African American Blacks. After accounting for key health indicators, BMI overweight status did not increase the chances of an e\GFR >130 but BMI-obesity in men did. Black people are more likely to be overweight than white peopleandblack and Asian groups have a higher risk of diabetes and heart disease, according to research from the Institute for Fiscal Studies. Other research identified older age at the time of donation as a potential risk factor for poorer renal function atrer donation in both Blacks and Caucasians [4]. Our initial findings suggested that both BMI and WC were positively associated with glomerular hyper filtration, as indicated by GFR > 130. This research is part of a larger study entitled "Stress and Psychoneuroimmunological Factors in Renal Health and Disease" that is funded by The National Center on Minority Health and Health Disparities under grant #1P20MD000512-04, "A Research Center to Reduce Ethnic Disparities in ESRD".

But the National Institute for Health and Care Excellence, which provides guidance for healthcare in England, has reported that the BMI cut-off points that determine if someone is overweight or obese are from previous studies of European-derived populations and may not be appropriate for other ethnic groups. [Accessed 03/03/2020], Source: CDC 2020.

The reasons for that aren't totally clear, but it may have to do with having reserves to draw on when fighting off an illness. Among women, BMI, WC, and eGFR were significantly and positively associated. Diabetes See Diabetes and African Americans "An individual's BMI will factor into whether they are allowed to undergo certain surgical procedures and can even affect the life or health insurance premium they can be offered.". Informed consent was obtained from all subjects. BMI was calculated by dividing weight (kilograms) by height (square meters). But judging whether a person is obese based only on their size is old-fashioned and not terribly useful, he says. Ellie and Natasia: What is the history behind sketch comedy? Black donors with obesity risk factors, when combined with GFR > 130 may be the factors placing overweight or obese AAs at increased risk for CKD after kidney donation. The Howard University Institutional Review Board approved the study protocol. Am J Kidney Dis 56: 303-312. People who are overweight are more likely to suffer from high blood pressure, high levels of blood fats, diabetes and LDL cholesterol.

We have identified potential risk factors which may lead to a better understanding of the role that overweight and obesity may play in the potential black kidney donor with the growing epidemic of obesity in the U.S., Black population. ", Tendai looks back on her experience with her doctors and feels like there was some "injustice.". "I ended up looking at fad diets, thinking maybe if I stopped eating I would lose weight. Data Query: Table 7_2_1_6_1.2b [Accessed 03/03/2020] While this may not be a factor in other ethnic groups, in Black donors this may be a manifestation of hyper filtration, particularly when combined with the additional hyper filtration that occurs when one is left with one functional kidney. For statistics on these related diseases, see: Your body type: Are you an apple shape or a pear shape? Your activity level: Someone who is very inactive may have a BMI in the normal range and have lots of body fat, though they may not look out of shape. Figure 1 illustrates the CART for females. Zhang H, Booney G (2000) Use of classification tees for association studies.

Psychoneuroimmunological Risk Factors in Renal Health and Disease was a cross-sectional study conducted by the National Minority Organ Tissue and Transplant Education Program (MOTTEP), a division of Howard University Hospital. "They have very low levels of muscle and bone -- often elderly people, those in poor shape, sometimes those who are sick. An age cut-off of 37 defined the next partition. But as it turns out, BMI alone may not be the best way to size up your shape.

-- Scott Kahan, MD. Results indicate that increased BMI (> 30 kg/m2), increased waist circumference (> 40 inches) and increased GFR (> 130 ml/min) were strongly correlated in Black volunteers. As a result, GFR and renal plasma flow rate increase. Table 1: Demographic and clinical data characteristics. https://nhqrnet.ahrq.gov/inhqrdr/data/query, Source: CDC 2020.

Of particular interest were patterns of association by gender. GFR was stratified into two categories: GFR less than or equal to 130 and GFR greater than 130. National Heart, Lung, and Blood Institute: "How Are Overweight and Obesity Diagnosed? In the beginning, Scola says, "I used BMI very strictly to measure my progress and see how well I was doing and I remember getting so excited when I was getting a lower number on the BMI scale. Health United States, 2018. Exclusion criteria for the community-based sample included current domestic and substance abuse, as well as, a previous diagnosis of a psychiatric disorder.

Gibney EM, Parikh CR, Garg AX (2008) Age, gender, race and association with kidney failure following living kidney donations. Not only is weight associated with reduced kidney functioning, but extensive evidence implicates increased body mass index (BMI) as a risk factor for hyper filtration [11-13]. Wuerzner G, Pruiim M, Maillard M, Bovet P, Renaud C, et al. Similarly, obese live kidney donors were also more likely to have a decrease in GFR [20]. Semin Nephrol 33: 14-22. To our knowledge, there has not been another study that has examined this association in a population that can be potential live-kidney donors.

Springer, New York. Characteristics of the sample are found in Table 1. "It's always about how you feel in yourself. "The standard definition of overweight is a BMI of 25 or above. https://nhqrnet.ahrq.gov/inhqrdr/data/query, Obesity is a risk factor for several diseases. Therefore, an African-American with a BMI of 28, which the standard chart calls overweight, might be as healthy as a white person with a BMI of 25. Hall JE (2003) The kidney, hypertension, and obesity. N Engl J Med 363: 724-732. "When I would go to the doctor they used BMI to tell me if I was overweight or if I was at a healthy weight.". A move from BMI to waist-to-height ratio may give an individual a more accurate indication of where they are health-wise. Scola now makes a conscious effort to not discuss her weight or height too much, to discourage her viewers from comparing themselves. mean serum creatinine levels were 0.87 0.19 mg/dl and mean eGFR was 129.67 48.39 mL/min/1.73 m2. Likewise, males with WC at or below 102 cm/40 inches were categorized as non-obese. But now she no longer feels like it's necessary. An illustration of the male CART is found in Figure 2. Factors that they identified as different in these Black donors have been increased creatinine clearances, increase blood pressures, and younger donor ages. BMI-categorized obese women were nearly 40 times more likely to have an eGFR > 130 than their normal BMI counterparts (OR = 39.493). This recent research [26-30] has identified the disproportionate need for kidney transplant on the part of Black donors who make up 12% of the donor pool but 44% of the donors subsequently placed on kidney transplant waiting lists. Classification and Regression trees (CARTs) [18] were analyzed to confirm logistic regression findings without imposed cut-offs. When one looks at the rapidly accumulating data [26-28] that identifies how the organs received and donated by Black's are associated with statistically significant poorer survival rates; one has to answer "maybe so." Waist size: For an accurate measurement, the tape measure should go around your waist at the top of your hip bones in your lower back and go around to the belly button. (2009) Impact of race and gender on live kidney donations. Frozen serum samples were sent to Quest Laboratories where they were thawed and assayed to measure serum creatinine using standardized ELISA techniques. JAMA 311: 579-586. The purpose of this study was to determine if being overweight and obese were associated with glomerular hyper filtration (as defined by an eGFR > 130) in a non-patient sample of African Americans. Their BMI puts them in the obesity range. For example, Asian-Americans tend to develop health risks, including the risk of diabetes, at lower BMIs than whites. WC-categorized obese men were nearly 16 times more likely to have an eGFR > 130 than their normal waist counterparts (OR = 15.989). "I even ended up drinking herbal detox teas. Transplantation 74: 1349-1351. Their blood sugar is excellent. Informed consent was obtained from all patients being included in the study. This is present among donors who are overweight and severely obese, [10]. "Ultimately, they have similar risks as people who carry lots of body fat and have a high BMI.". This manuscript poses a question that the Kidney Transplant Black/White disparity has recently raised concerns for the ethicists and transplant surgeons for some time. Fat stored in the stomach area is thought to be more dangerous than fat stored on the lower part of your body, such as your hips or thighs. The risk for complications among morbidly obese individuals has been emphasized in the literature and may have substantial relevance for AA.

", Joslin Diabetes Center: "Diabetes in Asians and Asian Americans. The final partitioning of this subset indicated that a systolic blood pressure of 157 was the cut-off where 26 females with SBP less than or equal to 157 had an eGFR > 130 and one female with SBP > 157 had an eGFR > 130. Unadjusted associations among study variables are found in Table 3 (Appendix 1, Appendix 2 and Appendix 3). "In order for me to move mentally forward, I felt like I needed to have this operation," she says. "I got to a point where it was starting to affect my life at home because I was doing everything I could for me to get to that BMI where I could desperately have this operation.

Self-reported data on hypertension and diabetes were provided by subjects based on a physician's previous diagnosis. Your age: The notion of an ideal BMI may shift with age. They don't seem to have any health effects associated with their excess weight.". Asian men should keep their waists no more than 35.5 inches and Asian women to no more than 31.5 inches, according to the Joslin Diabetes Center.
