Chronotype: Implications for Epidemiologic Studies on Chrono-Nutrition and Cardiometabolic Health

Limited research exists on the association between chronotype and dietary intake across different age groups.

• Chrono-nutrition involves the timing, frequency, and regularity of eating behaviors.
• Few studies have explored how an individual's chronotype affects the relationship between eating patterns and cardiometabolic health.
• Research on chronotype and dietary intake is particularly lacking in infants, children, and older adults.
• Most available evidence in adolescents and adults comes from cross-sectional surveys rather than longitudinal studies.
• There is a noted gap in understanding how chronotype relates to the three dimensions of chrono-nutrition.
• The potential role of chronotype in influencing the link between diet and cardiometabolic health outcomes is still unclear.
