Background:
Identifying when and where people overeat is important for intervention design, yet little is known about how unhealthy behaviours unfold in real life.

Aim:
To track the activities, social contexts and locations that co-occur with unhealthy snacking.

Methods:
Sixty-four adults (49F, mean age = 38.6 years) used electronic diaries to record snacking, location, social context and current activity every waking hour over 7 days. The proportion of snacking episodes that co-occurred with each location/activity/context was calculated by group and individual.

Results:
Over the group, snacking was most frequent whilst socialising (19.9% of hours spent socialising) or using the TV/computer (19.7%), when with friends (16.7%) and when at home (15.3%). All intra-class correlation statistics for cued behaviour were low, indicating the importance of within-person variability. There were marked individual differences between people in what constituted a ‘typical’ context for snacking.

Conclusions:
People show substantial differences in the contexts in which they snack. Tailoring interventions to these individual patterns of behaviour may improve intervention efficacy.
