In this one, an evening chronotype was associated with emotional eating in three diverse international cohorts.

- "Chronotype" describes the individual preference in sleep and wake timing.

An evening chronotype is usually described as a natural inclination toward later timing of eating patterns, sleep, and activity/work periods.

- This is the first study to evaluate the association between individual chronotype and emotional eating using the dim-light melatonin onset, the gold standard measure to assess the timing of the central clock, used to objectively characterize chronotype.

- This cross-sectional analysis includes data from four populations (ONTIME, ONTIME-MT, SHIFT, and DICACEM).

- Data suggested that emotional eating is more prevalent in individuals with an evening chronotype compared with those with a morning chronotype in populations with different cultural, environmental, and genetic backgrounds.

This happened when chronotype was determined subjectively (through a questionnaire), as well as when assessed objectively, by dim-light melatonin onset, in a large subsample of participants.

- This association was observed in a Spanish population (ONTIME) and was replicated findings in three international cohorts in the other Spanish study (ONTIME-MT), and in the Mexican cohort (DICACEM).

However, this relationship was not replicated in the smaller US cohort (SHIFT).

Evening types as determined by subjective and objective measures are more emotional eaters (open access)
