Brief Summary

'NUS Health' is a workplace-embedded health program for National University of Singapore (NUS) staff that concurrently targets sleep, sedentary behaviour, and physical activity. The intervention adopts a multilevel socioecological approach, integrating individual, social, environmental, and organisational strategies to support sustainable behaviour change. The study team will evaluate the feasibility, acceptability, and effectiveness of this program in improving sleep and movement behaviours, with anticipated downstream benefits for cardiometabolic health, psychological well-being, and workplace productivity. Findings from this study will inform the development of future institution-wide health initiatives and contribute to the evidence base for integrated workplace interventions targeting multiple lifestyle risk factors simultaneously.

Outcome Measures

Primary Outcomes (13)

  • Sendentariness, via OURA ring

    Amount of sedentary time daily, as measured by the OURA ring's sedentariness metric (energy expenditure of 1.5 metabolic equivalents (METs) or less ).

    Through study completion, daily, an average of 2 years

  • Moderate-to-vigorous activity (MVPA), via OURA ring

    Amount of daily moderate-to-vigorous activity (MVPA), as measured by the OURA ring.

    Through study completion, daily, an average of 2 years

  • Light-intensity physical activity (LPA), via OURA ring

    Amount of daily light-intensity physical activity (LPA), as measured by the OURA ring.

    Through study completion, daily, an average of 2 years

  • Sleep duration, via OURA ring

    Sleep duration as measured by the OURA ring.

    Through study completion, daily, an average of 2 years

  • Sleep duration variability

    The dispersion of daily sleep duration values around a participant's personal average.

    Through study completion, an average of 2 years

  • Sleep onset time, via OURA ring

    Sleep onset time as measured by the OURA ring.

    Through study completion, daily, an average of 2 years

Intervention

EXPERIMENTAL

The intervention involves the concurrent implementation of strategies to optimize sleep, reduce sedentary behaviour, and enhance incidental physical activity through an workplace embedded health promotion program. Participants will receive personalised goals and feedback based on their wearable-derived biometric data. An incentive system will be used to encourage engagement with the intervention and study procedures.

Behavioral: NUS Health Prog

Interventions

NUS Health ProgBEHAVIORAL

For the sleep component, personalised goals will focus on reducing or maintaining a low frequency of short sleep nights and, where appropriate, advancing sleep timing among individuals with delayed sleep schedules. Goals will be tailored to each participant using their biometric data. For the sedentariness component, personalised goals will focus on reducing daily sedentary time, with an overall target of approximately 8 hours per day or less. For the physical activity component, personalised goals will focus on increasing or maintaining moderate-to-vigorous physical activity (MVPA) levels.
