A new study entitled “Dose–Response Relationships of Moderate to Vigorous Physical Activity and Sedentary Time With Renal Function Indices in Adolescents With Reduced Renal Function: A Cross-Sectional Study” was recently published in Journal of Physical Activity and Health. A summary and citation are included below.
ABSTRACT
Background: This study aimed to explore the associations between moderate to vigorous physical activity (MVPA) and sedentary time with renal function indices in adolescents with kidney disease.
Methods: A cross-sectional study was conducted on 719 adolescents (median age 15 y, 40.6% female) with kidney disease from the National Health and Nutrition Examination Survey 2007–2016. The exposures were MVPA time and sedentary time. Renal metabolic parameters included serum uric acid (SUA), creatinine, blood urea nitrogen, the estimated glomerular filtration rate (eGFR), and the albumin creatinine ratio. Weighted multivariate regression analysis was used to estimate associations between exposures and outcomes.
Results: After stratifying MVPA time, the regression effect values β (95% CI) for MVPA on SUA (Q2: −0.22 [−0.41 to −0.03]; Q3: −0.32 [−0.53 to −0.11]) and creatinine (Q2: −0.08 [−0.15 to −0.01]; Q3: −0.04 [−0.11 to 0.03]) gradually decreased with increasing MVPA time. In males (−0.76 [−1.19 to −0.32]), MVPA time was significantly associated with lower SUA levels compared with females (−0.14 [−0.38 to 0.10]). Notably, female adolescents who had an MVPA time exceeding 420 minutes exhibited lower albumin creatinine ratio (−75.37 [−146.63 to −4.11]). In addition, both recreational MVPA time (−0.26 [−0.45 to −0.06]) and sedentary time (−3.15 [−5.83 to −0.46]) were negatively associated with eGFR.
Conclusions: Our study found an association between MVPA and lower levels of SUA in male adolescents with kidney disease and albuminuria in female adolescents with kidney disease. In addition, MVPA was also negatively associated with creatinine and eGFR, whereas sedentary time was only associated with eGFR. Further studies are needed to confirm these findings.
