Adherence to self-monitoring and behavioral goals is associated with improved weight loss in an mHealth randomized-controlled trial.

ABSTRACT:

Objective

The SMARTER mobile health (mHealth) weight-loss trial compared adherence to self-monitoring (SM) of diet, physical activity (PA), and weight and adherence to study-prescribed diet and PA goals between SM + feedback (SM + FB) and SM-only arms over 12 months.

Methods

Participants used digital tools to monitor their dietary intake, PA, and weight. We applied generalized linear mixed modeling to compare patterns of monthly adherence to SM and behavioral goals between groups over time and examine the association of adherence to SM and behavioral goals with ≥5% weight loss.

Results

The sample (N = 502) was 80% female and 82% White, with a mean (SD) BMI of 33.7 (4.0) kg/m². Adherence to SM and fat, calorie, and PA goals declined nonlinearly over time, wi
