Adherence
Wrist-worn actigraphy is a valid and recommended objective method for assessing sleep duration and timing, as well as physical activity and sedentary behavior, in obesity research.
For accurate tracking of sleep and activity, use a wrist-worn actigraphy device. It objectively measures your sleep duration and timing, which are linked to energy balance and weight regulation, offering more precise data than self-reports.
GoodSupportsHIGH confidence
Wrist-worn actigraphy is a wearable technology recommended as an objective surrogate measure of sleep duration and timing... wrist-worn actigraphy can also assess sleep behaviors... Obesity researchers can take advantage of these types of multiuse tools, creating efficiency and reducing the costs of their measurement activities.
Why this rating
Recommended by expert subgroup based on its ability to objectively measure key behaviors, though cost and expertise are barriers.

- Interviewer-assisted multiple-pass 24-hour dietary recalls are the most accurate and recommended method for assessing usual dietary intake in obesity treatment research, superior to self-administered web-based tools and food frequency questionnaires.Good
- Physical activity contributes to modest weight loss and improved weight-loss maintenance, with effects potentially occurring in a dose-response manner based on the magnitude of activity performed.Good
