Chronotype, temporal patterns of eating and diet composition on work and work-free days.

Temporal patterns of eating and diet composition are influenced by factors including circadian preference (chronotype) and work schedule, yet their combined influence is unknown. We investigated relationships between chronotype, temporal eating patterns (duration of eating window (DEW), time of first (FEO) and last (LEO) eating occasions), and diet composition on workdays (WD) and work-free days (FD). Non-shift workers ( = 39) completed the Chrononutrition Questionnaire (CNQ) (age: 38.

Time of day and glycaemic response in pregnant women: A gap in current guidelines?

Background & Aims: Advice to monitor and distribute carbohydrate intake is a key recommendation for treatment of gestational diabetes, but fails to consider circadian regulation of glucose homeostasis. In the non-pregnant state, glucose responses to a meal at night-time are significantly higher than during the day and are associated with an increased risk of developing type 2 diabetes. However, the impact of night time eating on postprandial glucose in pregnancy is uncertain.

Construct validity and test-retest reliability of a chrononutrition questionnaire for shift work and non-shift work populations.

The irregular eating patterns of both shift workers and evening chronotypes adversely affect cardiometabolic health. A tool that conveniently captures temporal patterns of eating alongside an indicator of circadian rhythm such as chronotype will enable researchers to explore relationships with diverse health outcome measures. We aimed to investigate the test-retest reliability and convergent validity of a Chrononutrition Questionnaire (CNQ) that captures temporal patterns of eating and chronotype in the general population (non-shift workers, university students, retirees, unemployed individuals) and shift work population.

Effects of (Poly)phenols on Circadian Clock Gene-Mediated Metabolic Homeostasis in Cultured Mammalian Cells: A Scoping Review.

Circadian clocks regulate metabolic homeostasis. Disruption to our circadian clocks, by lifestyle behaviors such as timing of eating and sleeping, has been linked to increased rates of metabolic disorders. There is now considerable evidence that selected dietary (poly)phenols, including flavonoids, phenolic acids and tannins, may modulate metabolic and circadian processes.

Effective interventions in preventing gestational diabetes mellitus: A systematic review and meta-analysis.

Background: Lifestyle choices, metformin, and dietary supplements may prevent GDM, but the effect of intervention characteristics has not been identified. This review evaluated intervention characteristics to inform the implementation of GDM prevention interventions.

Methods: Ovid, MEDLINE/PubMed, and EMBASE databases were searched.
