  1. N: sample size. Bold: statistically significant
  2. 1. Values are regression coefficients [95% confidence interval]. Coefficients should be interpreted for 1-hour increase for each time exposure, for eating occasions it should be interpreted as an increase in 1 eating occasion, for sleep dissatisfaction, it should be interpreted as a higher degree of dissatisfaction. Outcome: BMI. Multicollinearity test was performed, all GVIF < 10.
  3. 2. Model 0: Meal timing variables not mutually adjusted, i.e. three separate models. Adjustment variables: age, sex, adherence to Mediterranean diet, education, employment, mental health, smoking habit, physical activity, time of first meal, fasting hours, number of eating occasions, and energy intake
  4. 3. Model 1 same adjustment variables. Meal timing variables mutually adjusted in one sole model
  5. 4. Model 2 includes all the variables in Model 1 + sleep dissatisfaction and sleep time
