Abstract P132: Impact of Location and Social Context on the Probability of a Dietary Lapse Among Adults in Weight Loss Treatment
Background: Ecological momentary assessment (EMA) assesses individuals’ current experiences, location and social context in which behaviors occur. During a 12-mo behavioral weight loss intervention and using an EMA app, we asked participants to report any instances of temptations or a lapse from their weight management diet.
Objective: Estimate the rate of temptations per unit time and the probability that a lapse will follow based on the location (restaurant, home, work) and the social context (with others who are eating, completely alone).
Methods: Using a smartphone, participants initiated a report when they experienced a temptation and reported if this led to a lapse. Their location and the social context were recorded during the 5,211 self-reported temptations as well as during 106,960 random assessments over 12 mos.
Analyses: A frailty model was used to estimate the rate at which temptations occurred per unit of time and a logistic regression model was used to estimate the probability that a temptation led to a lapse both as a function of location and social context.
Results: The sample (N = 150) was predominantly female (90.7%) and White (80.7%), 56.4% were married with 16.4 (2.8) years of education and a mean BMI of 34.0 kg/m2 (4.6). Temptations occurred most often in a restaurant and the person was with others who were eating or in sight of others who were eating (Fig 1). While temptations occurred infrequently in another person’s home, there was nearly a 65% probability that a lapse would occur there. When with others who are eating, the temptation rate and probability of a lapse were high.
Conclusions: Temptations to eat in a manner that is inconsistent with a weight loss plan occur more frequently in certain locations, e.g., restaurants; however, the probability a temptation leads to a lapse is high in a variety of locations and social contexts, e.g., with others who are eating. Interventions need to focus on empowering individuals trying to manage their weight to resist temptations in these at risk locations and social contexts.
