简要总结
This study evaluates the effect of different dietary conducts in the nocturnal period on the postprandial metabolism and food perceptions of night workers of the Hospital of Clinics of Uberlândia, Federal University of Uberlândia.
详细描述
Due to imbalances in the circadian rhythm, shift workers may present inadequate eating habits, which provoke metabolic and nutritional disorders. In this crossover study the participants consumed, at different times and separated by 6 days interval, two meals pre-established at the time of night work: a control and a higher-protein. On the day of each intervention, the participants were evaluated for response of blood and subjective markers after meal (glucose, insulin, triglycerides and subjective perceptions related to ingestion after each meal). It is expected that the standardization of a glycemic reduction diet will improve the metabolic response of the workers, demonstrated in the results of the biochemical parameters. If this scenario is confirmed, it is still expected that the data and results obtained in this study may serve as subsidies for the elaboration of nutritional interventions consistent with the work routine at night.

结局指标
主要结局
Change of food perceptions
时间窗: 7 months
To evaluate appetite, satiety and postprandial satisfaction, a visual analogue scale called "hunger and satiety scale" was applied before and after consumption of the proposed meal, with the questions, "How much hunger did you have before the meal?"; "After the meal, how did you feel?"; "How much did you like the meal?", signaling all responses on a 0 to 10 cm scale. There is no classification of the values obtained. The answers are subjective and used in a comparative way.
Change of metabolic parameters
时间窗: 7 months
Blood samples were collected before and after (30, 60, 90 and 120 minutes) the consumption of each of the meals at nighttime (work schedule). In the first meal of the following day (standard breakfast) were determined the serum concentrations of glucose (mg/dL).
