An observational study in Health Behavior, Diet, Healthy and Physical Activity, sponsored by National University of Singapore. Completed at 1 site in Singapore. Open to participants aged 21 Years to 69 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-09-19.

The aim of this study is to advance understanding of behavioural risk factors for cardiovascular disease and type 2 diabetes in Singapore.
BACKGROUND: Modifiable risk factors for non-communicable diseases, including unhealthy diets and movement behaviours, are influenced by complex and dynamic interactions between people and their social and physical environment. Therefore, understanding patterns and determinants of these risk factors as they occur in real-life is essential to enable the design of precision public health interventions.
AIMS: The aims of this study are to (1) examine patterns of dietary and movement behaviours in real-time as people go about their daily lives, (2) examine how interactions with the social and physical environment influence dietary and movement behaviours, and (3) examine how these patterns differ by ethnicity and other socio-demographic characteristics.
METHOD: This is an observational study in free-living participants over 10 consecutive days, with a 9-day follow-up 6 months later. 1500 participants will be recruited from a large prospective cohort study. Real-time data capture strategies will be used: an ecological momentary assessment (EMA) app with global positioning system (GPS) enabled to collect location data, accelerometers to measure movement, and wearable sensors to monitor blood glucose levels. Participants receive six EMA prompts per day to capture information on diet and movement behaviours (physical activity, sedentary behaviour, sleep), and related contextual factors. A second wave of EMA prompts and GPS monitoring will occur 6 months later. Data will be integrated and analysed using generalised linear models to examine associations between behavioural risk factors and contextual determinants.
National University of Singapore is the lead sponsor of 206 studies on the registry; 52 are open to participants now.

Exclusion criteria:
Movement behaviours
Movement behaviours (i.e., physical activity, sedentary behaviour, sleep) are measured using a wrist-worn accelerometer.
Time frame: continuously for 9 days.
Glucose concentrations
Glucose concentrations are measured using a continuous glucose monitor sensor.
Time frame: in 15-minute intervals over 9 days.
Self-reported food intake
Self-reported food intake measurement through entering of food items and the social and physical environment of eating via an Ecological Momentary Assessment (EMA) smartphone app.
Time frame: Change in self-reported food intake over time. Data will be collected at 2.5-hour intervals between 8am and 9.30pm over a period of 9 days, and repeated at the 6-month follow-up
Self-reported movement behaviours
Self-reported movement behaviours (i.e., physical activity, sedentary behaviour, sleep) through entering of the type and social and physical environment context of activity via an Ecological Momentary Assessment (EMA) smartphone app.
Time frame: Change in self-reported movement behaviours over time. Data will be collected at 2.5-hour intervals between 8am and 9.30pm over a period of 9 days, and repeated at the 6-month follow-up
Self-reported screen time
Self-reported screen time through entering of the type of screen used and the purpose and the duration of screen time via an Ecological Momentary Assessment (EMA) smartphone app.

Self-reported stress levels
Self-reported stress level will be assessed via an Ecological Momentary Assessment (EMA) smartphone app.
Time frame: Data will be collected 6 times per day for 9 days, and repeated at the 6-month follow-up.
Self-reported fatigue
Self-reported fatigue will be assessed via an Ecological Momentary Assessment (EMA) smartphone app.
Time frame: Data will be collected 6 times per day for 9 days, and repeated at the 6-month follow-up.
