Objective: This study evaluated whether desiring to lose weight is associated with subsequent changes in social contact with individuals perceived to be thinner or heavier.
Methods: Longitudinal data were used to examine associations between desiring to lose weight at baseline and social contact with thinner and heavier individuals across a 1-year follow-up period (N = 9,335, 2013-2014 Gallup National Panel). How baseline social contact is linked to body mass outcomes among those desiring to lose weight (N = 7,134) was also examined.
Results: Over time, individuals desiring to lose weight interacted more frequently (+69 interactions/year, on average) and were more likely to possess social ties (tie probability +0.12) with heavier individuals while lessening their interactions (-51 interactions/year) and decreasing their likelihood of ties (tie probability -0.048) with thinner individuals. On the other hand, increasing contacts and interactions with thinner individuals, and declining contacts and interactions with heavier individuals, were linked to actual weight loss.
Conclusions: Using national longitudinal data, an important mismatch was demonstrated between the social contacts created by individuals desiring weight loss and the contextual factors possibly useful for weight loss. This may help to explain why weight loss is often unsuccessful.
