Study Details

Study Description

Brief Summary

This study will compare eating behaviors and measures of hunger and fullness between day and night workers in order to better understand why night workers are at increased risk for obesity and related diseases.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Day worker

Men and women who work only day shift for at least 3 consecutive days of the week

Behavioral: Portion size
The amount of food served (g) at the first two meals of each day. These amounts will vary across 4 weeks.

Active Comparator: Night worker

Men and women who work only night shift for at least 3 consecutive days of the week

Behavioral: Portion size
The amount of food served (g) at the first two meals of each day. These amounts will vary across 4 weeks.

Outcome Measures

Primary Outcome Measures

  1. Food intake [24-hours intake period]

    Food by weight (g) in response to variations in portion served

  2. Energy intake [24-hours intake period]

    Food by energy (kcal) in response to variations in portion served

  3. Energy density consumed [24-hours intake period]

    Energy density consumed (kcal/g) in response to variations in portion served

Secondary Outcome Measures

  1. Appetite-regulating hormones [2-hours measurement period]

    Appetite-regulating hormones, including Glucagon-like-peptide 1 (GLP-1) and ghrelin will be analyzed from plasma from whole blood samples collected while fasted and at 30, 60, 90, and 120 min postprandial. Area under the curve of plasma concentrations will be calculated for each individual appetite-regulating hormone

  2. Hunger and fullness [24-hours measurement period]

    Subjective measures related to hunger, fullness, and prospective consumption will be measured before and after meals via visual analog scales. The range of scores are 0 mm to 100 mm, with higher scores indicating greater feelings of the corresponding measure (e.g. greater hunger). Post-meal measures, adjusted for the corresponding pre-meal measure, will be analyzed as individual outcomes. Area under the curve will also be calculated for each measure.
