Lower prognostic nutritional index is associated with a greater decline in long-term kidney function in general population.
Background: The prognostic nutritional index (PNI) is an integrated index of serum albumin and peripheral lymphocyte count, where low values may reflect poor nutritional status or inflammation. The long-term effect of PNI on renal function is not well known in the general population. Therefore, we investigated whether the PNI is related to renal function changes in the general population.
Methods: Data from participants who underwent a health check-up between 2002 and 2018 were retrospectively examined. PNI was computed by 10×serum albumin (g/dL) + 0.005×total lymphocyte count (per mm3). The primary exposure was PNI, divided into quintiles. The primary outcome was a 25% decline in eGFR from baseline over a 5-year follow-up period.
Results: This study included 15,437 participants (mean [standard deviation, SD] age, 43.7 [7.9] years; 46% male). The median (interquartile ranges) 5-year change of eGFR was - 5.2 (- 18.8, - 3.3) mL/min/1.73m2. A total of 2,272 participants (14.7%) experienced a 25% decline in eGFR at 5 years. Compared to the highest PNI group, lower PNI groups were at greater risk for a 25% decline in eGFR; odds ratios and 95% confidence intervals were 1.42 (1.20, 1.68), 1.23 (1.04, 1.45), 1.21 (1.03, 1.43), and 1.19 (1.01, 1.40) for the first to fourth quintiles of PNI, respectively. In linear regression analyses, lower PNI groups also showed a larger decline in eGFR over 5 years compared to the highest PNI group.
Conclusions: Lower PNI was associated with a larger decline in renal function in the general population.
期刊介绍：
Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered.
Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies.
In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
