Two Dietary Patterns From China Might Benefit Kidney Function, as Indicated by Latent Profile Analysis

Area of Science:

• Nutrition Science
• Nephrology
• Public Health

Background:

• Diet significantly influences chronic kidney disease (CKD) progression.
• A specific dietary pattern to promote kidney health is lacking.
• Identifying beneficial dietary patterns is crucial for preventing renal function decline.

Purpose of the Study:

• To identify latent dietary patterns beneficial for kidney health in China.
• To assess dietary patterns associated with lower incidence of chronic kidney disease.

Main Methods:

• Cross-sectional survey of 4,267 adults in the China Health and Nutrition Survey (2009).
• Kidney function assessed using uric acid, urea, and creatinine levels.
• Latent profile analysis used to identify dietary patterns from 24-hour recalls.

Main Results:

• Two dietary patterns showed potential kidney benefits: low animal/high plant diet and high cereal/vegetable diet.
• These patterns were characterized by higher intake of plant-derived foods like cereals, legumes, fruits, and vegetables.
• Specific median intakes for key food groups within each pattern were detailed.

Conclusions:

• Two distinct dietary patterns in China may benefit kidney function.
• Further research is needed to confirm these findings.
• These patterns can inform the design of targeted dietary interventions for kidney health.
