NUS Health Study: Improving Sleep, Sedentariness and Physical Activity in NUS Staff

'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.

Inclusion Criteria: * Full time NUS staff * Willing to undergo blood draw procedure Exclusion Criteria: * Staff who tender their resignation from NUS during the 16-month study period will be discontinued from the study.
