(HealthDay News) — High/consistent self-weighing is associated with increased eating self-efficacy over time, according to a study presented at the American Heart Association’s Epidemiology and Prevention/Lifestyle and Cardiometabolic Health 2016 Scientific Sessions in Phoenix.

Yaguang Zheng, PhD, RN, from Boston College in Chestnut Hill, Massachusetts, and colleagues conducted an analysis of data from a 12-month behavioral weight-loss interventional study. Participants were given a Wi-Fi-enabled scale to transmit weight data, and were classified into 3 self-weighing patterns: high/consistent (more than 6 days/week), moderate/declined (declined from 4 to 5 to 2 days/week), and minimal/declined (5 to 6 to 0 days/week). 

Self-efficacy was assessed semiannually using the Weight Efficacy Lifestyle scale, yielding ratings of one’s confidence to avoid overeating under varied conditions.

The researchers identified a significant group effect for changes in the subscale score of negative emotions, a group-by-time effect for social pressure, and a time effect for positive activities. From baseline to 6 or 12 months, the high/consistent self-weighing group showed significant increases in each subscale score and total score, with the subscale score of social pressure having a marginally significant increase at 12 months. 

No changes over time were seen in the other 2 groups.

“Participants in the high/consistent self-weighing group reported increased self-efficacy over time for eating in different contexts,” the researchers wrote. “Future work needs to explore strategies to improve eating self-efficacy and self-weighing for those unable to establish this habit.”
