Brief Summary

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.

Conditions

Shift Work Type Circadian Rhythm Sleep Disorder

Keywords

Food intake; Sleep; Shift work; Postprandial metabolic response

Outcome Measures

Primary Outcomes (4)

• Change of metabolic parameters

  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).

  7 months

• Change of metabolic parameters

  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 insulin (mU/mL).

• Change of metabolic parameters

  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 triglycerides (mg/dL).

  7 months

• Change of food perceptions

  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.
