Study Explores Link Between Diet and Recurring Urinary Tract Infections

by Ella

A recent study published in JAMA Network Open delved into the potential impact of behavioral factors, including diet, body weight, and lifestyle, on the prevalence of urinary tract infections (UTIs). UTIs, a common health concern affecting millions worldwide, can significantly diminish quality of life and pose serious health risks if left untreated.


Urinary tract infections, driven primarily by bacterial pathogens such as Escherichia coli, are influenced by various risk factors including age, sexual behavior, anatomical differences between genders, immune function, and contraceptive methods. The misuse of antibiotics further complicates treatment by fostering pathogen resistance.


Untreated UTIs can lead to severe complications such as pyelonephritis, renal failure, and pose risks during pregnancy. Recurrences are common and influenced by a myriad of lifestyle and health-related factors.


Diet and lifestyle are recognized as pivotal in preventing UTIs, with proper nutrition, adequate hydration, and healthy habits essential for reducing recurrence risks and bolstering immune resilience.


About the Study:

The study adopted a cross-sectional observational approach, utilizing a comprehensive 39-item questionnaire to explore the frequency of urinary infections in relation to behavioral risk factors. The questionnaire’s development was informed by existing literature, expert opinions, and the characteristics of the target population.


Conducted between July and August 2023, the survey targeted employees and students across three university centers in Romania. Emphasis was placed on maintaining participant anonymity and data protection to ensure confidentiality and accurate responses. The study received ethical approval from the University of Medicine and Pharmacy in Craiova.

Key Findings:

Analysis of the data, gathered from 1,033 valid responses predominantly from women, revealed notable insights into the relationship between dietary habits and UTI frequency. Notably, urinary infections were more prevalent among women, consistent with existing gender distribution patterns.

Anthropometric data analysis highlighted a significant proportion of respondents, particularly males, classified as overweight or obese. Younger individuals, particularly those aged 26-35, were identified as the most susceptible to urinary infections.

The study underscored the influence of dietary choices on UTI frequency, with healthier diets correlating with lower infection rates, particularly among women over 45. Factors such as age, education level, weight, and infection frequency significantly impacted dietary habits, with younger individuals, rural residents, and those with lower education levels more likely to adhere to unhealthy diets.

In addition to diet, lifestyle factors such as physical activity levels were found to influence UTI frequency, with sedentary behaviors associated with higher infection rates.


The findings of this study shed light on the complex interplay between dietary habits, lifestyle factors, and UTI recurrence rates. Understanding these dynamics is crucial for developing effective preventive strategies and improving UTI management outcomes. Further research is warranted to explore these relationships comprehensively and guide targeted interventions aimed at reducing UTI burden and enhancing overall health and well-being.
