Association of Evening Eating with Sleep Quality and Insomnia among Adults in a Brazilian National Survey

“…It is worth mentioning that the self-reported largest meal may have questionable accuracy, as demonstrated in previous studies, 34,35 attributed to individuals' challenges in accurately estimating their caloric intake and their tendency to confuse the perception of plate size with the actual calories consumed. Nevertheless, overeating and consuming a substantial amount of food, regardless of its energy density, close to bedtime, can negatively impact sleep quality.…”

“…Although there are no previous studies that have used TEM to analyze the effects of circadian eating timing on sleep, the study that first proposed it 31 was justified by the consequences of evening eating on circadian misalignment, previously highlighted by numerous experimental and observational studies. 25,26,[34][35][36][37][38][39] Both evening eating and evening latency, defined as the duration of time between the last eating event and sleep onset, are part of chrononutritional behaviors that can misalign the phase of an individual's circadian rhythm and negatively influence health. 34,35 Findings suggested that eating late and close to bedtime may contribute to poor sleep and misalignment of the melatonin phase, 22,23 besides affecting weight, weight-related health outcomes such as insulin resistance, metabolic disease, and inflammation.…”

“…According to the Chrononutrition Profile Questionnaire, 34 35 evening eating refers to the clock time of the last eating event, and it was assessed by asking participants: ‘Considering your habits during the last month, on a typical weekday/workday (or weekend/free/day): What time do you usually have your last eating event?’, and responses were in 30-minute increments. The instrument clarified that it included any food and/or drink that contained calories.…”

“…The weekly average clock time of the last eating event was calculated as follows: ([5 Â evening eating timing on weekdays] þ ]2 Â evening eating timing on weekends])/7. 34,35 Participants were also asked: 'What is your largest meal of the day? ',-which refers to the meal in which participants consume the greatest amount of calories, and possible responses were: Breakfast, lunch, dinner, none, or other.…”
