Abstract
ObjectiveTo analyze the age-related changes in estimate glomerular filtration rate (eGFR) and its association with nutrition, inflammation and sex hormones for the purpose of providing clues for in-depth research on and clinical prevention and treatment of age-related eGFR decline.
MethodsA multi-center, cross-sectional large sample epidemiological survey was performed. A total of 520 healthy individuals (224 males and 296 females) were enrolled and divided into adult group (age < 65 years) and elderly group (age ≥65 years). The calorie and nutrient intake were calculated through retrospective dietary investigation. The eGFR was calculated with the chronic kidney disease epidemiology collaboration (CKD-EPI) formula, and the changes of inflammatory cytokines, sex hormones, and biochemical indexes were also detected. The multivariate linear regression analysis was used to analyze the correlation between eGFR and those indexes of the overall population, adult group, and elderly group.
Results(1) In both the males and females, eGFR decreased with age (P<0.01), and no significant difference was found between the males and females (P>0.05). (2) A significant positive correlation was found between eGFR and testosterone, estradiol, or progesterone in the adult women (P<0.01). (3) The independent influencing factors of eGFR were body mass index (BMI), mean arterial pressure, serum albumin, serum transferrin, interleukin-6 (IL-6), estradiol, progesterone, fiber intake, thiamine, and niacin intake in the overall population. The independent influencing factors of eGFR were mean arterial pressure, serum albumin, high sensitivity C reactive protein (hsCRP), estradiol, and magnesium intake in the adult group, and were only IL-6 in the elderly group.
ConclusionWith the progressive decrease of eGFR with age, the inflammatory status was an important influencing factor in the healthy population, especially in the elderly group. And there was a significant correlation between eGFR and sex hormones in the adult women.
