Article Abstract

Background: Dietary patterns, as a comprehensive dietary indicator, may influence the risk of developing overactive bladder (OAB). However, it remains unclear whether dietary patterns independently affect the development of OAB.

Objective: This study aimed to identify specific dietary patterns using principal component analysis (PCA) and evaluate their associations with the risk of OAB, thereby providing new insights for OAB prevention and management.

Methods: Dietary patterns were identified by applying PCA, and their associations with OAB risk were analyzed. After adjusting for three known confounders (age, sex, and BMI), four key dietary patterns were determined: (1) PC5: Antioxidant-balanced pattern, OR = 0.96, 95% CI (0.94-0.97),  < 0.05; (2) PC16: Diversified low-alcohol pattern, OR = 0.92, 95% CI (0.89-0.94),  < 0.05; (3) PC18: Whole-grain high-alcohol pattern, OR = 1.04, 95% CI (1.01-1.07),  < 0.05; (4) PC22: High-fiber low-sugar pattern, OR = 0.93, 95% CI (0.90-0.96),  < 0.05.

Results: The findings indicated that the antioxidant-balanced (PC5), diversified low-alcohol (PC16), and high-fiber low-sugar (PC22) dietary patterns were associated with a decreased risk of OAB, while the whole-grain high-alcohol pattern (PC18) exhibited a dual effect. Specifically, when considered independently, the high-fiber low-sugar pattern showed a protective effect; however, when combined with the whole-grain high-alcohol pattern, it increased the risk of OAB.

Conclusion: Dietary patterns are independent factors influencing the development of OAB. In particular, the antioxidant-balanced, diversified low-alcohol, and high-fiber low-sugar patterns help reduce OAB risk, whereas the whole-grain high-alcohol pattern exerts a dual effect.

Towards more balanced dietary guidelines: connecting climate, culture, and nutrition.

Proc Nutr Soc

September 2025

Department of Agricultural Economics and Rural Development, University of Göttingen, Göttingen, Germany.

Objective: The transformation of food systems has emerged as a critical component of global climate action, with food-based dietary guidelines (FBDGs) increasingly recognised as a key policy tool to promote both public health and environmental sustainability. However, despite their importance, many national FBDGs fail to integrate sustainability considerations or adequately support diverse plant-based dietary patterns.

Design: This review proposes a socioecological framework for enhancing the inclusivity and adaptability of FBDGs, enabling them to better reflect evolving food systems and consumer behaviours while strengthening their role in promoting sustainable and health-conscious diets.

Background: Shift work is associated with irregular dietary habits and poor nutritional intake, increasing the risk of chronic diseases. This study aimed to assess dietary quality and nutritional intake according to shift work status among Korean adult workers.

Methods: Data from 15,121 adult workers aged ≥20 years from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 2013 and 2021 were analyzed.

Background: Type 2 Diabetes Mellitus (T2DM) is a chronic metabolic disease characterized by insulin resistance and progressive decline in pancreatic beta cell function. It is a public health problem of great magnitude that has been increasing globally over the last 4 decades. The latest research has found that sugar-sweetened beverages (SSBs), as an important dietary risk factor, are closely related to the occurrence and development of T2DM.
