Abstract

Background: Working during the night interferes with the timing of normal daily activities and is associated with an increased risk of chronic diseases. Under controlled experimental conditions, interventions focusing on sleep and nutrition can mitigate the short-term adverse effects of shift work. However, it is unclear how these results translate to real-life, how they can be targeted to individual conditions, and how they relate to long-term health. Therefore, the current study aims to implement a personalized sleep and nutritional intervention among night shift workers in the field.

Methods: A non-blinded controlled intervention study is used, consisting of a run-in period, an intervention of 3 months, post-intervention measurements, and a follow-up after 12 months. Three study arms are included: sleep intervention, nutritional intervention, and control group (n = 25 each). Participants are healthy 18-60-year male night shift workers, with at least one year of experience in night shift work. Information from the run-in period will be used to personalize the interventions. The main outcomes are sleep measurements and continuous interstitial glucose levels. Furthermore, general health biomarkers and parameters will be determined to further evaluate effects on long-term health.

Discussion: This study aims to mitigate negative health consequences associated with night shift work by introducing two personalized preventive interventions. If proven effective, the personalized interventions may serve as practical solutions that can have a meaningful impact on the sustainable health and employability of night shift workers. This study will thereby contribute to the current need for high-quality data on preventative strategies for night shift work in a real-life context.

Trial registration: This trial has been registered under ClinicalTrials.gov Identifier NCT06147089. Registered 27 November 2023.

Schematic overview of the study. White represents measurements that will be gathered during a study visit. Green indicates measurements that will be taken during the 14-day period (covering night shifts, rest days, and non-night shifts) and monitored remotely. Grey indicates online measurements taken outside of a study visit. The follow-up occurs 12 months after the baseline visit. NU = nutritional intervention

Baseline measurements are used to personalize the intervention. (1) Measurements collected during baseline, including sleep (via actigraphy watch, sleep diary, and sleep questionnaires), dietary behaviors (via food logging), and glucose metabolism (via continuous glucose monitoring and the Phenflex test with different blood based biomarkers measured pre- and postprandially). (2) These data and their interactions are visualized and analyzed to (3) personalize the sleep or nutritional advice
