Nutritional Epidemiology of Cardiometabolic and Urological Health: Diet Quality, Biomarkers, and Circadian Factors

Recent advances in nutritional epidemiology increasingly highlight the complex interplay between dietary patterns, metabolic biomarkers, and circadian factors in shaping the risk for cardiometabolic and urological conditions. Cardiometabolic diseases, including obesity, diabetes, and cardiovascular pathologies, along with urological disorders, are dominant contributors to global morbidity and diminished quality of life. While numerous studies substantiate the pivotal role of diet quality and nutrient intake, mounting evidence now emphasizes the influence of circadian rhythms, such as meal timing and sleep patterns, as well as the mechanistic insights afforded by metabolic, inflammatory, and hydration-related biomarkers. Despite these advances, many gaps persist, including limited integration of circadian behaviours with dietary exposures, incomplete characterization of precision biomarkers, and under-explored nutritional links to urological health within diverse and at-risk populations.This Research Topic aims to advance the scientific understanding of how diet quality, nutritional biomarkers, and circadian timing jointly impact cardiometabolic and urological health across the life course. The primary goal is to foster research examining associations and mechanistic pathways between nutrient intake, dietary patterns, and clinical endpoints in these domains, while also evaluating the predictive value of both traditional and novel biomarkers. Additionally, this topic seeks to encourage exploration of how circadian and behavioural factors, such as meal frequency, timing, and sleep, modulate disease risk and progression, and whether integrative approaches combining dietary, biomarker, and chronobiological data offer improved models for disease prevention or risk stratification.Focusing on human populations, the research topic encompasses epidemiological, clinical, and translational investigations into the relationships among diet, biomarkers, and circadian influences. To gather further insights in the scope of these relationships, we welcome articles addressing, but not limited to, the following themes:o Diet quality indices, dietary patterns, and cardiometabolic risko Nutritional determinants of urological health, including kidney, bladder, and prostate outcomeso Application and validation of nutritional and metabolic biomarkerso Chrononutrition, circadian disruption, and behavioural timing (e.g., meal timing, sleep, shift work)o Integrative approaches linking diet, biomarkers, and circadian patternso Population disparities, sex- and age-specific effects, and life-course perspectiveso Methodological advances in dietary assessment, biomarker use, and epidemiological modelling Topic editors: Shan Yin, Sharifa Alblooshi Source: https://www.frontiersin.org/research-topics/84414/nutritional-epidemiology-of-cardiometabolic-and-urological-health-diet-quality-biomarkers-and-circadian-factors
