Background Little is known about the association between self-weighing frequency and weight gain prevention, particularly in worksite populations. Purpose The degree to which self-weighing frequency predicted 2-year body weight change in working adults was examined. Method The association between self-weighing frequency (monthly or less, weekly, daily, or more) and 24-month weight change was analyzed in a prospective cohort analysis (n=1,222) as part of the larger HealthWorks trial. Results There was a significant interaction between followup self-weighing frequency and baseline body mass index. The difference in weight change ranged from ?4.4±0.8 kg weight loss among obese daily self-weighers to 2.1±0.4 kg weight gain for participants at a healthy weight who reported monthly self-weighing. Conclusion More frequent self-weighing seemed to be most beneficial for obese individuals. These findings may aid in the refinement of self-weighing frequency recommendations used in the context of weight management interventions.
