Abstract

Background Identifying potentially modifiable risk factors is critically important for reducing the burden of chronic kidney disease. We sought to examine the association of body mass index (BMI) with kidney function decline in a cohort of young adults with preserved glomerular filtration at baseline.Study design Longitudinal cohort.Setting & participants 2,839 black and white young adults with cystatin C-based estimated glomerular filtration rate (eGFRcys)>90mL/min/1.73m(2) taking part in the year-10 examination (in 1995-1996) of the Coronary Artery Risk Development in Young Adults (CARDIA) Study.Predictor BMI, categorized as 18.5-24.9 (reference), 25.0-29.9, 30.0-39.9, and ≥40.0kg/m(2).Outcomes Trajectory of kidney function decline, rapid decline (>3% per year), and incident eGFRcys <60mL/min/1.73m(2) over 10 years of follow-up.Measurements GFRcys estimated from the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation for calibrated cystatin C at CARDIA years 10, 15, and 20.Results At year 10, participants had a mean age of 35.1 years, median eGFRcys of 114mL/min/1.73m(2), and 24.5% had BMI≥30.0kg/m(2). After age 30 years, average eGFRcys was progressively lower with each increment in BMI after adjustment for baseline age, race, sex, hyperlipidemia, smoking status, and physical activity. Higher BMI category was associated with successively higher odds of rapid decline (for 25.0-29.9, 30.0-39.9, and ≥40.0kg/m(2), adjusted ORs were 1.50 [95% CI, 1.21-1.87], 2.01 [95% CI, 1.57-2.87], and 2.57 [95% CI, 1.67-3.94], respectively). 18 participants (0.6%) had incident eGFRcys<60mL/min/1.73m(2). In unadjusted analysis, higher BMI category was associated with incident eGFRcys<60mL/min/1.73m(2) (for 25.0-29.9, 30.0-39.9, and ≥40.0kg/m(2), ORs were 5.17 [95% CI, 1.10-25.38], 7.44 [95% CI, 1.54-35.95], and 5.55 [95% CI, 0.50-61.81], respectively); adjusted associations were no longer significant.Limitations Inability to describe kidney function before differences by BMI category were already evident. Absence of data for measured GFR or GFR estimated from serum creatinine level.Conclusions Higher BMI categories are associated with greater declines in kidney function in a cohort of young adults with preserved GFR at baseline. Clinicians should vigilantly monitor overweight and obese patients for evidence of early kidney function decline.

  • Alterations in renal excretory function occur prior to the onset of obesity hypertension in animal models and humans.

    “Longitudinal studies have shown that alterations in renal excretory function occur prior to the onset of obesity hypertension in animal models and humans (61;62) indicating that renal dysfunction may drive arterial pressure elevation in obesity.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
