Compared to Q1, Q3 participants had higher odds of meeting HbA1c (OR 1.650, 95% CI 1.280-2.126) and blood pressure targets (OR 1.770, 95% CI 1.358-2.308), and combined achievement of HbA1c, BP, and LDL-C targets (OR 2.745, 95% CI 1.356-5.561, p=0.005).

Population

1,465 adult diabetic patients from the Guangdong section of the Chinese Diabetes Complications Study

Comparison

Highest quartile of a 'healthy dietary pattern'… vs Lowest quartile of the 'healthy dietary pattern'

Design

Cross-sectional

Overview

A healthy dietary pattern is associated with significantly better achievement of blood glucose, blood pressure, and lipid targets in adult diabetic patients, independent of total caloric intake.

Key Points

  • This study aims to investigate the connection between dietary patterns and metabolic management in adults with diabetes in Guangdong.
  • Data from the Chinese Diabetes Complications Study involving 1,465 patients were analyzed.
  • Dietary habits were assessed using a semi-quantitative food frequency questionnaire.
  • Principal component analysis identified dietary patterns; logistic regression analyzed associations with metabolic metrics.
  • Q3 participants had an OR of 1.650 (CI 1.280 - 2.126, p<0.001) for meeting HbA1c targets compared to Q1.
  • The OR for blood pressure targets in Q3 versus Q1 was 1.770 (CI 1.358 - 2.308, p<0.001).
  • The combined odds of meeting HbA1c, BP, and LDL-C targets was 2.745 (CI 1.356 - 5.561, p=0.005).
